PURPOSE OF THE STUDY Increased tibial slope facilitates anterior translation of tibia relative to the femur, thereby increasing the load on both the native and replaced anterior cruciate ligament. This study aims to retrospectively review the posterior tibial slope in a cohort of our patients after the ACL reconstruction and revision ACL reconstruction. Based on the results obtained by measurements, we aimed to confirm or disprove the claim that the increased posterior tibial slope is one of the risk factors of the ACL reconstruction failure. Another aim of the study was to assess whether there are any correlations between the posterior tibial slope and basic somatic parameters (height, weight, BMI) or the patient s age. MATERIAL AND METHODS The posterior tibial slope was measured retrospectively on lateral X-rays of 375 patients. There were 83 revision reconstructions and 292 primary reconstructions performed. The patient s age at the time of injury, height and weight were recorded and the BMI was calculated. The findings were then statistically analysed. RESULTS The mean posterior tibial slope in 292 primary reconstructions was 8.6 degrees, whereas the mean posterior tibial slope in 83 revision reconstructions was 12.3 degrees. The difference between the studied groups was statistically (p<0.0001) and substantively significant (d=1.35). In the breakdown into men and women, the mean tibial slope was 8.6 degrees in the group of men with primary reconstruction and 12.4 degrees in the group of men with revision reconstruction (p < 0.0001, d = 1.38). A similar result was achieved in women where in the group with primary reconstruction the mean tibial slope was 8.4 degrees, while in the group with revision reconstruction it was 12.3 degrees (p < 0.0001, d = 1.41). Furthermore, a higher age in men at the time of revision surgery (p = 0.009; d = 0.46) and a lower BMI in women at the time of revision surgery (p = 0.0342; d = 0.12) were observed. Conversely, neither height nor weight were different, both when comparing the whole groups and the groups in a breakdown by sex. DISCUSSION As regards the main aim, our results are in line with the results reported by majority of other authors, and they are substantively significant. The posterior tibial slope is a significant risk factor in anterior cruciate ligament replacements, with tibial slope above 12 degrees increasing the risk of ligament failure, namely both in men and women. On the other hand, this is obviously not the sole cause of the ACL reconstruction failure since there are also other risk parameters. It is not yet clear whether it makes sense to indicate correction osteotomy before the ACL replacement in all patients with an increased posterior tibial slope. CONCLUSIONS Our study confirmed a greater posterior tibial slope in the revision reconstruction group compared to the primary reconstruction group. Thus, we confirmed that greater posterior tibial slope may be a factor leading to the ACL reconstruction failure. Since the posterior tibial slope is easily measured on the baseline X-rays, we recommend to perform this measurement routinely before each ACL reconstruction. In the case of a high posterior tibial slope, slope correction should be considered to prevent potential ACL reconstruction failure. Key words: anterior cruciate ligament reconstruction, ACL graft failure, morphological risk factors, posterior tibial slope.

PURPOSE OF THE STUDY: Superior Capsule Reconstruction (SCR) of the shoulder joint has recently been included in the portfolio of interventions as a solution to irreparable rotator cuff tears. One of the options is to use a long head of the biceps tendon (LHBT) autograft. This paper presents the fi rst clinical outcomes of the SCR of the shoulder joint using the LHBT autograft. MATERIAL AND METHODS It is a prospective non-randomised study in which 14 patients were included, namely 7 men and 7 women. The patients were evaluated using the pain VAS, UCLA (The University of California at Los Angeles) Shoulder Rating Scale and ASES (The American Shoulder and Elbow Surgeons) Shoulder Score. The minimum follow-up was 12 months after surgery. The measured values were analysed using the standard statistical methods. RESULTS From August 2020 to January 2022, a total of 14 SCR with biceps tendon autograph were performed at our department. The mean age of the patients was 62 years (40-72). The mean value of the UCLA Shoulder Score was 12.36 ± 2.92 points preoperatively, while after surgery the obtained values increased to the mean value of 28.86 ± 3.08 points. The ASES score was 25.48 ± 3.89 points preoperatively and 82.41 ± 7.95 points at one year after surgery. The preoperative mean VAS score was 6.14 ± 1.10 points and 1.36 ± 0.93 points at one year after surgery. The mean active shoulder fl exion measured preoperatively was 140 degrees, whereas at one year after surgery it was 171 degrees. The mean active abduction reached 123 degrees before surgery and 169 degrees after surgery. The mean active external rotation of the shoulder joint was 59 degrees preoperatively and 52 degrees postoperatively. The mean active external rotation at 90 degrees of abduction was 52 degrees preoperatively and 60 degrees postoperatively. Whereas the improvement as against the preoperative status measured by the UCLA, ASES and pain VAS was signifi cant, the differences in the range of motion were signifi cant in the case of active fl exion and abduction only. DISCUSSION Painful irreparable rotator cuff tear constitutes an indication for SCR. The reconstruction is performed using autografts, allografts and xenografts. In literature, several SCR surgical techniques using a long head of the biceps tendon have been presented. In most of these techniques the supraglenoid insertion of the LHBT was left intact. Our study showed a signifi - cant relief from problems and good functional outcomes at 1 year after surgery when the biceps tendon had been used. Similar results are reported also by other studies using the biceps tendon for SCR. When comparing this study and the other study we published earlier on SCR with xenografts, there is no signifi cant difference in the clinical outcomes between these two techniques. On the very contrary, they are slightly better in some parameters. CONCLUSIONS Arthroscopic SCR of the shoulder joint with the biceps tendon reports good clinical outcomes at one year after surgery both with regard to the relief from problems and range of motion. Due to low morbidity of graft harvesting, low cost, and easy surgical technique, it appears to be the fi rst-choice method for superior capsule reconstruction of an irreparable tear of supraspinatus or infraspinatus if the long head of the biceps tendon is preserved. A longer follow-up period and evaluation of a larger study population would be necessary to defi nitely confi rm the success rate of the described procedure. KEY WORDS: massive rotator cuff tears, irreparable rotator cuff tears, superior capsular reconstruction, autograft, long head of the biceps tendon.

PURPOSE OF THE STUDY This study aimed to evaluate the clinical outcomes and the rate of recurrence in patients who had undergone arthroscopic Bankart repair with remplissage for anterior instability of the glenohumeral joint. MATERIAL AND METHODS The study included 96 arthroscopic Bankart procedures with remplissage performed between 2013 and 2019 at our department in 93 patients (81 men and 12 women; with the mean age of 33 years). We gathered and analysed preoperative data, including a 3D-CT scan of the affected shoulder. Apart from stability, the functional results were assessed postoperatively using the WOSI, SSV, Rowe score, and by measuring the strength of shoulder girdle muscles. The non-parametric MannWhitney U-test was used to identify the predisposing factors for recurrence of glenohumeral instability. RESULTS The arthroscopic Bankart repair with remplissage was indicated in 74 shoulders for primary TUBS and in 22 shoulders as a revision procedure. The recurrent instability was observed in 13 of 96 operated shoulders (13.5%). Subjective instability (positive apprehension test in the extreme positions of the shoulder joint, in abduction and external rotation in particular) was reported by 10 patients (10/13; 77%), three patients experienced a redislocation of the glenohumeral joint in the postoperative follow-up (3/13 patients; 23%). The risk of recurrence of the glenohumeral instability was not correlated with either the number of previous stabilisation procedures, or any other preoperative or intraoperative parameters. Conversely, a new postoperative injury was a factor of key importance. The patients with recurrent instability (subjective instability or glenohumeral dislocation) achieved a significantly lower Rowe score, SSV, postoperative VAS, and worse overall satisfaction with the procedure compared to the group with no recurrent instability. The remplissage induced minor limitations of external rotation at 0° abduction and internal rotation at 90° abduction. After rehabilitation, the muscle strength of the operated shoulder in both groups was comparable to that of the untreated shoulder in all planes of the shoulder range of motion. DISCUSSION Our study confirms the clinical relevance of the addition of remplissage to the arthroscopic Bankart procedure for reducing the rate of recurrent glenohumeral instability in TUBS with a clinically significant Hill-Sachs lesion. Satisfaction with the surgical outcome is high; the functional outcomes are very good, including muscle strength. Surprisingly, though, the risk of recurrent instability does not correlate with the number of implants used in the stabilisation procedure. CONCLUSIONS Addition of remplissage to the arthroscopic Bankart stabilisation in patients with a clinically significant Hill-Sachs lesion shows a low risk of recurrence of glenohumeral instability after surgery compared to the conventional arthroscopic Bankart repair alone. The remplissage does cause minor restrictions in the glenohumeral joint external rotation, but it was not reflected in the satisfaction of patients or a lower clinical score of the shoulder joint. The preoperative assessment of the HillSachs lesion using the "glenoid track" on a 3D-CT scan helps improve the preoperative planning and prediction of outcomes of the stabilisation procedure. Key words: glenohumeral instability, Bankart defect, Hill-Sachs lesion, Bankart repair, remplissage, arthroscopy.

PURPOSE OF THE STUDY Shoulder instability is often times accompanied by associated injuries caused by the humeral head displacement. These are primarily bone lesions on the head and socket of the glenohumeral joint. The purpose of this study was to evaluate the frequency, morphology and clinical significance of bone lesions in shoulder instabilities in a group of patients operated in our department for glenohumeral instability between 2012 and 2019. MATERIAL AND METHODS The ongoing evaluation included 373 patients with trauma and habitual instability who had undergone surgery in our department in the period from 2012 to 2019. All patients underwent a preoperative 3D CT scan of the shoulder joint. Subsequently, the morphology and clinical significance of individual bone lesions were evaluated based on the older Burkhart s concept of engaging/nonengaging lesions and the newer concept of glenoid track by Yamamoto and Di Giacomo of 2007, 2014 or 2020. RESULTS The frequency of Hill-Sachs lesion was 83.4% (311) in our group of patients. In nearly two thirds (211 cases) also a bone defect on glenoid was detected (59.3%). When comparing the basic types of instabilities, in the TUBS group the Hill-Sachs lesions were present up to twice as often as in the group with AMBRI instability. Clinically significant Hill-Sachs lesions according to the older concept of engaging/ nonengaging lesions of Burkhart were reported in 104 cases (34%). Clinically significant lesions according to the newer concept of Yamamoto and DiGiacomo (the so-called off-track lesions) were observed in 173 cases (55.6%). Classified as critical were the clinically insignificant lesions (the so-called on-track lesions), which by their location were near the glenoid track. These lesions were found in 80 patients. After adding up the significant (off-track) and critical on-track lesions, we arrived at 253 (81.4%) clinically significant lesions based on the updated Yamamoto concept. DISCUSSION The frequency of Hill-Sachs lesions and glenoid defects identified by us is close to the upper limit of the range described in literature (8 to 100%). Based on the recent study by Yamamoto, added to these defects were the so-called peripheral ontrack defects, the clinical significance of which is currently indisputable. The oldest classification into engaging/nonengaging lesions revealed only 34% of the significant lesions, but this concept does not evaluate the glenoid defect. The newer concept by Yamamoto/DiGiacomo resulted in detecting 55.6% of significant Hill-Sachs lesions. The latest modification of the glenoid track of 2020, which includes also the on-track lesions in the critical zone among the significant lesions, in our group of patients classified 81% of lesions as clinically significant. CONCLUSIONS Our study confirmed the very frequent occurrence of clinically significant Hill-Sachs lesions in shoulder instabilities. Therefore, for the sake of successful shoulder stabilisation surgery detailed preoperative planning with 3D CT of the shoulder joint and evaluation of the associated bone lesions are necessary. The highest detection of clinically significant lesions was achieved by the latest modification of the glenoid track concept. Future studies will have to prove the effect of this classification on the result of surgical treatment. Key words: shoulder instability, glenoid track; bone defects, Hill-Sachs lesion; bipolar lesions; 3D CT evaluation.

PURPOSE OF THE STUDY We present the results of the retrospective study comparing the clinical outcomes of outside-in versus all-inside suture techniques of unstable RAMP lesions (RL) of the medial meniscus in patients with simultaneous ACL lesion with a minimum two-year follow-up. MATERIAL AND METHODS The retrospective evaluation covered two groups of patients who underwent the arthroscopic repair of unstable RL in combination with anterior cruciate ligament reconstruction (ACLR). Group 1 included 42 patients (28 men/24 women). Group 2 consisted of 36 patients (21 men/15 women). In Group 1, RL suture repair using the outside-in technique by posteromedial approach with absorbable PDS suture was performed, while in Group 2 the all-inside technique of RL suture via the standard anteromedial portal was applied using the Fast-Fix system (Smith Nephew, USA). The evaluation was done preoperatively and postoperatively with the mean follow-up of 27.9 months in Group 1 and 30.1 months in Group 2. The patients were assessed using the subjective IKDC score and the side-to-side difference (SSD) in ventral laxity was measured by Genourob (GNRB) laximeter at the applied pressure of 134 N and 250 N. Moreover, the failure rate of RAMP lesion repair, ACL graft, necessity of secondary partial meniscectomy and return to pre-injury level of sport were analysed. RESULTS The median IKDC score increased in Group 1 from 56 points preoperatively to 92 points postoperatively and in Group 2 from 58 points preoperatively to 90 points postoperatively (p>0.05). The median value of SSD in ventral laxity of the knee measured by the GNRB laximeter at the applied pressure of 134 N in Group 1 was 5.6 mm preoperatively and 1.9 mm postoperatively and in Group 2 it was 5.9 mm preoperatively and 2.3 mm postoperatively. At the pressure of 250 N, the median value in Group 1 was 7.9 mm preoperatively and 2.7 mm postoperatively and in Group 2 it was 8.1 mm preoperatively and 3.2 mm postoperatively. When comparing the SSD of the groups postoperatively, no statistically significant difference was found (p>0.05). Revision arthroscopy was performed in 8 patients. In 1 patient (2.4 %) in Group 1 and in 4 patients (11.1%) in Group 2 a rerupture of the RL of the meniscus occurred and partial meniscectomy was performed. In Group 2, statistically significant higher occurrence of the RL suture failure (p<0.05) was reported and there was a need to perform partial medial meniscectomy (p<0.05). The ACL graft failure was observed in 2 patients (4.7%) in Group 1 and in 3 patients (8.3%) in Group 2 (p>0.05). 31 evaluated patients (73.8%) from Group 1 and 24 patients (66.7%) from Group 2 (p>0.05) returned to the pre-injury level of sports activities. DISCUSSION When comparing the outcomes of individual techniques of the RL repair published in recent literature with our conclusions, we may state that the results of subjective as well as objective criteria achieved were similar to those reported by other authors worldwide. No study has so far been published which would compare the outcomes of the by us presented two surgical techniques of the RL suture in an ACL-deficient knee with a minimum follow-up of 24 months. CONCLUSIONS Both the surgical techniques of unstable RL repair in combination with the ACLR using a tendon graft result in a statistically significant improvement of clinical outcomes postoperatively. In Group 2, with the all-inside RL repair, a statistically significant higher failure rate of RL repair was confirmed as well as the need to perform secondary partial meniscectomy compared to Group 1. Key words: RAMP lesion, ACL-deficient knee, unstable medial meniscus lesion, repair of meniscus, all-inside technique, posteromedial technique, ACL reconstruction.
PURPOSE OF THE STUDY Anterior cruciate ligament reconstruction is one of the most common reconstruction surgeries. The unintended consequences of the surgery are hemarthrosis, blood loss, knee swelling and postoperative pain. The purpose of the study was to evaluate the effect of a single dose of intravenous tranexamic acid (TXA) on the postoperative parameters and functional status of the knee joint 3 months after surgery. MATERIAL AND METHODS It is a prospective randomised clinical study. An intravenous injection of TXA equivalent to 15 mg/kg in 100 ml of saline solution was administered to the test group during the surgery (20 minutes before the end of the surgery). The control group was administered 100 ml of saline solution without TXA. In both groups, the following parameters were evaluated preoperatively and postoperatively (on Day 1 and Day 10 and at 1 month and 3 months): thigh circumference at 1 cm above the patella, Coupens and Yates (CY) score for swelling, and pain score (VAS). At 24 hours after the surgery, the blood loss (secretion into the drain) and decrease in hemoglobin (Hb) and hematocrit (HCT) levels compared to the preoperative levels were assessed. The functional status of the knee joint was assessed based on the Lysholm knee scoring scale and the IKDC subjective knee evaluation form preoperatively, or at 1 and 3 months postoperatively. RESULTS In the test group, a significantly lower blood loss was detected 24 hours after the surgery. The mean difference of 128 ml compared to the control group was both statistically and practically significant (p < 0.001, d =1.42). The test group showed a lower decrease in Hb and HCT levels postoperatively compared to the control group, although with no statistical significance. On the first postoperative day, slightly better results of the thigh circumference at 1 cm above the patella and of the CY score were observed in the test group. However, during the follow-up check performed postoperatively on Day 10, the differences in the thigh circumference at 1 cm above the patella, CY score and pain VAS score were negligible. The differences in the functional status of the knee joint between the two groups ascertained during the check performed 1 month and 3 months after the surgery were insignificant. DISCUSSION Our study, just like other studies, confirms a significant effect of a single dose of intravenous TXA on the volume of blood loss and early postoperative swelling, which are the parameters affecting the early postoperative course. Even though the intervention does not affect the subsequent result of surgery, it can undoubtedly be of benefit perioperatively. There is a fairly limited number of randomised clinical studies on this topic in literature, with most of them published in the last 7 years. Further research should, among other things, optimise the protocol and identify a suitable candidate for TXA administration in patients undergoing an ACL reconstruction. CONCLUSIONS Our study confirmed the positive effect of a single dose of intravenous TXA during the reconstruction of anterior cruciate ligament using hamstrings on early postoperative blood loss and early postoperative swelling, which can have a positive effect on wound healing and prevent postoperative complications. Therefore, in agreement with available literature, we recom mend administering a single dose of intravenous TXA in ACL reconstruction, unless there is a contraindication to this therapy. Key words: anterior cruciate ligament reconstruction, hamstrings tranexamic acid, single intravenous administration, clinical evaluation.

PURPOSE OF THE STUDY Two-year clinical results of a multicenter prospective randomized study in patients with arthroscopically treated Femoro - acetabular Impingement syndrome and concurrently performed microfracture for grade IV chondral lesions of the acetabulum. MATERIAL AND METHODS The study evaluated a group of 55 patients of the originally enrolled 92 patients with the underlying diagnosis of FAI syndrome with intraoperatively confirmed grade IV acetabular chondropathy of up to 4 cm2 in size, who had undergone a comprehensive hip arthroscopy (correction of structural cam-type and/or pincer-type deformity, labral refixation or partial labral resection etc.) performed by two experienced surgeons. The patients were randomized intraoperatively using a closed envelope method into two groups. In Group 1 (31 patients), microfractures for chondral defects was performed, while in Group 2 the patients underwent a defect debridement procedure only. The studied group included a total of 7 professional and 48 recreational athletes (33 men and 22 women), with the mean age of 34.4 in Group 1 and 31.1 in Group 2. Preoperatively and 6, 12 and 24 months postoperatively the modified Harris Hip Score (mHHS) parameters and VAS score were evaluated and also revision surgeries, conversion to endoprosthesis, and occurrence of complications were recorded. RESULTS Preoperatively, no statistical difference between the two groups was found in the studied parameters (mHHS and VAS). Postoperatively (after 6, 12 and 24 months), in both groups a statistically significant increase in mHHS and VAS score was reported. When comparing the mHHS parameter at individual evaluated times in Group 1 and Group 2, a statistically significant difference was confirmed at 12 and 24 months after surgery (P < 0.001), namely in favour of Group 1. At 6 months postoperatively, no statistically significant difference in this parameter between the two groups was confirmed (P = 0.068). When comparing the VAS score parameter in these two groups at individual times, no statistically significant difference was confirmed at 6 and 12 months after surgery (P= 0.83 / P= 0.39). A statistically significant difference in the VAS score parameter was observed only at 24 months after surgery, namely in favour of Group 1 (P< 0.037). In the course of the follow-up period, altogether 3 patients (2 patients from Group 1) were indicated for revision hip arthroscopy and in 1 female patient an endoprosthesis was implanted. No severe intraoperative or postoperative complications were observed. DISCUSSION In agreement with other authors worldwide, the arthroscopic treatment of FAI syndrome, if indicated and performed correctly, was confirmed to improve the clinical condition of patients postoperatively, regardless of the technique used in treating the chondral defect. Based on our results as well as conclusions of other world authors, in treating the grade IV defects of smaller size it is appropriate, in treating the cartilage, to prefer the microfracture surgery, which is less demanding both technically and financially and contrary to mere debridement allows to fill the original defect by fibrocartilage tissue. CONCLUSIONS The benefits of the acetabular microfracture in patients with the FAI syndrome treated arthroscopically were confirmed. A statistically significant difference between the two studied groups was reported in the mHHS parameter at 12 and 24 months after surgery and also in the VAS parameter at 24 months in favour of the group with performed microfracture. In both the studied groups, the arthroscopy resulted in a statistically significant improvement of the assessed quality of life parameters. Key words: hip arthroscopy, femoroacetabular impingement syndrome, chondral defect, microfracture, abrasive chondroplasty.

INTRODUCTION The anterior cruciate ligament (ACL) reconstruction is a tried and tested method in treating knee joint instability which brings valuable results in an acceptable time frame. In the long-term follow-up, however, a higher risk of knee osteoarthritis development is described. One of the possible reasons is considered to be the abnormal kinematics of the operated knee. The purpose of our study was to determine the degree to which the ACL reconstruction helps restore the correct gait cycle compared to the healthy limb. MATERIAL AND METHODS The study included patients after the ACL reconstruction performed in the period from 1 January 2016 to 31 March 2018. With the use of strict criteria, 11 patients were selected for kinematic analysis, who underwent examinations in a gait laboratory and were also evaluated using the Tegner and Lysholm rating systems and the IKDC (International Knee Documentation Committee) knee score, namely preoperatively and at 6 and 12 months postoperatively. The kinematic assessment of gait was carried out using the Vicon MX system with the placement of reflexive markers in line with the Plug-In Gait model. RESULTS The clinical outcomes (namely the score according to Tegner, Lysholm as well as the IKDC) during the first year postoperatively showed a major improvement in knee function and the achievement of the pre-injury activity level. The kinematic analysis revealed lower knee extension at the stance phase and lower overall range of motion of the limb with the injured ACL compared to the healthy limb. The follow-up evaluation at 6 and 12 months postoperatively showed a persisting between-limbs difference in knee extension, whereas the range of motion gradually improved during the year. CONCLUSIONS Although our study confirmed that the ACL reconstruction is an efficient method to treat knee joint instability, it also indicated that even at one year after the ACL reconstruction, the kinematics of the operated knee was not fully restored to the level of the heathy knee. The persisting limb-difference in gait kinematics could contribute to the gradual development of degenerative changes in the operated knee joint. Key words: anterior cruciate ligament deficiency, anterior cruciate ligament reconstruction, knee kinematics during gait, knee osteoarthritis.
PURPOSE OF THE STUDY Irreparable rotator cuff tear continues to be a point of discussion. Several surgical techniques have been proposed so far. None of them, however, can be considered the method of choice. This study presents the first clinical results of superior capsule reconstruction (SCR) using the DX Reinforcement Matrix. MATERIAL AND METHODS The evaluation included patients with the minimum follow-up of 6 months. The follow-up period in these patients was 1 year (6-18 months) on average. The active (AROM) and passive (PROM) ranges of motion were assessed-anterior flexion, abduction, external rotation and external rotation at 90° abduction. The patients were assessed using clinical scores before and after the surgery-pain assessment scale (VAS), UCLA (University of California at Los Angeles) Shoulder Rating Scale and ASES (American Shoulder and Elbow Surgeons) Shoulder Score. RESULTS In the period from October 2016 to October 2018, a total of 20 SCRs were performed. The mean age of patients was 61 years. Nine patients were clinically assessed, with the mean follow-up of 1 year. The mean UCLA Shoulder Score was 10 points preoperatively. Postoperatively, the values went up to 29 points on average. The reported ASES score was 23.8 points preoperatively. Postoperatively, the mean score was 73.2 points. The VAS subjective pain score ranged around 7 points before the surgery. After the surgery, the mean VAS score was 2 points. The mean active shoulder flexion was 74° preoperatively and 161° postoperatively. The mean active abduction was 74° preoperatively and 161° postoperatively. The mean active external rotation of the shoulder joint was 20° preoperatively and 56° postoperatively. The mean active external rotation at 90° abduction was 21° preoperatively and 82° postoperatively. The changes in all the followed-up mean parameters of UCLA, ASES, VAS, AROM and PROM reported by our group show a relatively high level of substantive significance. DISCUSSION Results of arthroscopic superior capsule reconstruction using the DX Reinforcement Matrix have not been published in literature so far. Compared to the results for fascia lata published in literature, our results are slightly worse. By contrast, our results are similar to those achieved by human dermal allograft. CONCLUSIONS Arthroscopic superior capsule reconstruction currently appears to be the method of choice in unreconstructed supraspinatus and infraspinatus tear. Our group of patients shows that early clinical outcomes of SCR using xenograft are very promising. A significant pain relief and a considerable improvement in the range of motion of the operated shoulder joint were observed. No complication specifically associated with the use of xenograft has been reported as yet. A longer follow-up period and assessment of a larger group of patients will be necessary to confirm the success of this surgical procedure. Key words: massive rotator cuff tears; irreparable rotator cuff tears; superior capsular reconstruction; xenograft; DX Reinforcement Matrix.

PURPOSE OF THE STUDY The prospective study evaluates the short-term outcomes of endoscopic treatment of calcar calcanei in patients who underwent unsuccessfully more than 6 months of conservative therapy. MATERIAL AND METHODS Our study included 34 patients with refractory plantar fasciitis, in whom endoscopic treatment of inferior calcar calcanei with partial plantar fasciotomy was performed in the period from 01. 01. 2009 to 31. 07. 2015. The assessed parameters were the following: level of function, pain relief and patient satisfaction on the FAAM (Foot and Ankle Ability Measure) score and VAS (Visual Analog Scale) score with the minimum follow-up of 1 year. RESULTS A marked increase in the FAAM score from 39.2 preoperatively to 94.0 one year after the surgery and also a major pain relief on the VAS score from the initial 8 to the median 0 were observed. In total, 79.4% of patients were symptom-free one year after the surgery. The recurrence of calcar calcanei or ossification was seen on the radiograph taken one year after the surgery in 8 patients (23.5 %). DISCUSSION In our opinion, the most important outcome of our study is the considerable reduction in pain postoperatively (the median VAS score declined from 8 to 0 one year after the surgery) and concurrently a notable increase in the FAAM score (from 39.2 preoperatively to 94.0 one year after the surgery). Similar results of endoscopic partial fasciotomy were achieved also by some other authors. Therefore, this method can be considered validated. It has also been proven that the correlation between the calcar calcanei recurrence, or a higher BMI and recurrence of symptoms postoperatively is insignificant. CONCLUSIONS The endoscopic treatment of inferior calcar calcanei and plantar fasciotomy with denervation of fascial attachment is a fast, minimally invasive and safe method which brings very satisfactory results in the treatment of refractory plantar fasciitis. It is evidenced by subjective patient satisfaction, great function improvement, considerable pain relief after the surgery together with a minimum incidence of complications.
