PURPOSE OF THE STUDY: Intraarticular fractures of the distal femur rank among the most severe musculoskeletal injuries. Various treatment options, such as plate osteosynthesis or retrograde nailing, can be employed. This study aims to evaluate the clinical outcomes and complications of intraarticular distal femoral fractures treated with retrograde femoral nail, with particular emphasis on C3 fractures. MATERIAL AND METHODS: Between January 2016 and January 2023, 18 AO/33.C3 fractures were treated with a retrograde femoral nail. Of these, two were classified as 33.C1, eight as 33.C2 and eight as 33.C3. Twelve of the fractures were open. After the initial treatment and stabilizing the patient's overall condition, we proceeded with the definitive osteosynthesis. The first phase involved open reduction and fixation using individual screws to reconstruct the articular surface. The second phase consisted in retrograde nailing with correction of the length, axis and rotation of the femur. The evaluation criteria included: complication rate, number of revisions, knee range of motion, mechanical axis and length of the lower extremity, progression of gonarthrosis, pain level, need of walking support, Lysholm and Tegner Activity Score for functional outcome. RESULTS: Overall, we evaluated the complications and the outcomes of 12 patients (13 fractures). Of these, 8 patients experienced some kind of postoperative complications, primarily insufficient healing or nonunion, which were managed through revision surgery. Plate reosteosynthesis was used in 2 patients who were then excluded from the final clinical evaluation. No cases of deep infection or deep vein thrombosis were reported and no patient required total knee replacement. Seven AO/33.C3 fractures were individually evaluated. The average knee range of motion was nearly 0-93°, maximum flexion was 120°. On average, the lower extremity was 1.6 cm shorter and 7.3° varus to the mechanical axis. Only little progression of gonarthrosis was observed along with low levels of pain. The Lysholm Score ranged between 52 and 84 points (averaging 73.1). The mean Tegner Activity Score was 3.4. All results showed adequate improvement in 33.C2 and 33.C1 groups. DISCUSSION: The retrograde femoral nail demonstrates several advantages over the locking compression plate, particularly in biomechanical aspects. Various clinical studies have reported superior outcomes in terms of healing, complication rate, blood loss and functional outcome. Our study findings align with some of those international studies, particularly in the rate of infectious complications (0%), mean Lysholm Score (79.3 p.) and Tegner Activity Score (4.1). On the other hand, we observed a higher rate of revision surgery (53.8 %), mainly due to evaluating 33.C fractures only. The main advantage of this method lies in complete visualization, leading to better reconstruction of the articular surface coupled with excellent biomechanical properties of the intramedullary nail. CONCLUSIONS: Intraarticular distal femoral fractures pose significant challenges to treatment and frequently lead to permanent damage. The primary treatment goals involve achieving anatomical reposition of the articular surface, stable osteosynthesis, correction of the femoral length and axis and early rehabilitation. Our study demonstrates good clinical outcomes with a relatively low rate of complications. Patients are capable of walking without pain, achieving a good range of motion, returning to their occupations and becoming self-sufficient. Moreover, there were no infectious complications and no significant progression of gonarthrosis. KEY WORDS: retrograde femoral nail, intraarticular distal femoral fracture, functional outcome, complication rate.

PURPOSE OF THE STUDY Carpometacarpal (CMC) instabilities of the thumb joint occur after injuries or due to joint overload in patients with congenital joint hypermobility. They are often undiagnosed and, if left untreated, are the basis for the development of rhizarthrosis in young individuals. The authors present the results of the Eaton-Littler technique. MATERIAL AND METHODS The authors present a set of 53 CMC joints of patients with an average age of 26.8 years (15-43 years) operated on in the years 2005-2017. Post-traumatic conditions were found in 10 patients and in 43 cases instability was caused by hyperlaxity, also demonstrated in other joints. The operation was performed from the Wagner's modified anteroradial approach. After the operation, a plaster splint was applied for 6 weeks, after which rehabilitation (magnetotherapy, warm-up) began. Patients were evaluated using the VAS (pain at rest and during exercise), DASH score in the work module, and subjective evaluation (no difficulties, difficulties not limiting normal activities, and difficulties limiting normal activities) before surgery and 36 months after surgery. RESULTS During the preoperative assessment, the average VAS value was 5.6 at rest and 8.3 during exercise. During the VAS assessment at rest, the values at 6, 12, 24 and 36 months after surgery were 5.6, 2.9, 0.9, 1, 2 and 1.1. When evaluated in the given intervals under load, the detected values were 4.1, 2, 2.2 and 2.4. The DASH score in the work module was 81.2 before surgery, 46.3 at 6 months, 15.2 at 12 months, 17.3 at 24 months, and 18.4 at 36 months after surgery. In the subjective self-assessment made at 36 months after surgery, 39 patients (74%) assessed their condition as having no difficulties, ten patients (19%) reported difficulties that did not limit normal activities, and four patients (7%) reported difficulties limiting normal activities. DISCUSSION Most authors present the results of their surgeries in patients with post-traumatic joint instability, and they report excellent results at two to six years after surgery. There is a negligible number of studies addressing instabilities in patients with instability caused by hypermobility. When using the conventional method described by the authors in 1973, our results of the evaluation performed at 36 months after surgery are comparable to those reported by other authors. We are well aware of the fact that this is a short-term follow-up and that this method does not prevent developing degenerative changes in the case of long-term follow-up, but reduces clinical difficulties and may delay the development of severe rhizarthrosis in young individuals. CONCLUSIONS CMC instability of the thumb joint is a relatively common disorder, although not all individuals experience clinical difficulties. In the case of difficulties, the instability needs to be diagnosed and treated as this is how the development of early rhizarthrosis in the predisposed individuals can be prevented. Our conclusions suggest a possibility of a surgical solution with good results. Key words: carpometacarpal thumb joint, thumb CMC joint, carpometacarpal thumb instability, joint laxity, rhizarthrosis.

PURPOSE OF THE STUDY It was a prospective, randomised, unblinded study. Effects of the application of platelet-rich fibrin (PRF) on the anatomic anterior ligament reconstruction were examined. MATERIAL AND METHODS A total of 40 patients who underwent a surgery between 2012 and 2014 were enrolled in the study. The patients were randomised into two groups: the group with PRF application (n=20) and the group without PRF application (n=20, control group). The study included 11 women and 29 men, with the mean age at the time of inclusion into the study 29.1 years. Vivostat ® PRF was obtained perioperatively from the patient s blood and applied intraoperatively to the hamstring tendon graft. The ACL graft healing was assessed through magnetic resonance (MRI) at 6 and 12 months postoperatively. The clinical outcomes (the Lysholm score and the IKDC Subjective score, return to pre-injury sport levels, Pivot-shift test, graft failure) as well as standardised laxity measurements using GenouRob arthrometer were performed preoperatively and 12 months after surgery. RESULTS The study was completed by thirty-three (33) patients (17 in the PRF group and 16 in the control group). In two cases, postoperative graft failure was reported (both cases in the control group). No significant differences were found in the process of graft ligamentization evaluated through MRI (p=0.07). No significant difference between the groups was identified with respect to return to pre-injury sport levels (p=0.232), or the Lysholm score and IKDC Subjective score (p=0.259, and p=0.364 respectively). The postoperative knee laxity measurement using Genourob arthrometer did not reveal any significant differences between the PRF group and the control group. DISCUSSION Results similar to those arrived at by our study have recently been published also by other authors worldwide. We can therefore assume that the application of PRF can be of benefit, especially at the early stage of healing. The results still need to be verified on a larger study group, the study design should focus on the development in the early postoperative period. CONCLUSIONS In our study group, no significant difference was observed in the evaluated subjective and objective clinical parameters. Only the parameter regarding the ACL graft failure fell just short of statistical significance, namely to the disadvantage of the group without the PRF application. Key words: anterior cruciate ligament, arthroscopy, anatomic ACL reconstruction, magnetic resonance imaging of the graft, platelet-rich fibrin, graft healing, MRI signal intensity of the graft.

Osteoid osteoma is a primary benign bone tumor with rare intra-articular occurrence. Our case report describes a rare case of a 21-year-old man with long-term severe pain in the right hip region caused by osteoid osteoma managed by arthroscopic excision. The clinical finding of pains and a limited range of motion did not correlate with the normal plain X-ray finding. The osteoid osteoma was suspected based on the CT scan. In literature, several methods of resection of intraarticular osteoid osteoma of the hip are described. Since our department has long specialised in arthroscopic hip surgery and based on the available examinations the tumor appeared to be located within the arthroscopic reach, we decided for arthroscopic resection of the tumor. Our study comprises a detailed description of the entire surgical procedure, the used arthroscopic approaches and the arthroscopic technique of tumor excision. The histological examination of samples taken from the mass confirmed the suspected osteoid osteoma. The success of arthroscopic excision of the tumor was later confirmed also by very positive postoperative recovery when the patient very soon experienced a considerable reduction of pain observed during our five-year follow-up of the patient (Day 13, Week 2 and 6, Year 1, 2 and 5). During the follow-up period, an increase of the Harris Hip Score (13.5 preoperatively vs 76.6/91/94/96/96 postoperatively) and a decrease in VAS (9 preoperatively vs. 3/1/1/1/1) were reported. The follow-up CT and MRI performed at 2 or 5 years after surgery did not show tumor recurrence. The case report includes also illustrations consisting of X-rays, CT and MRI scans before and after surgery as well as multiple scans taken intraoperatively. It has to be emphasized that this is a rare case and an evaluation of a larger group of patients would be necessary to verify the successful outcomes of arthroscopic technique in treatment of the hip joint osteoid osteoma.

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.
INTRODUCTION: Hip arthroscopy is a common procedure in hip preservation surgery. Its complication rate is relatively low. This prospective multicentric study evaluates complication rate in patients undergoing primary hip arthroscopy. MATERIALS AND METHODS: The study cohort consisted of 908 patients mean age of 37 years (14-67 years). Patients were prospectively included in the study in the years 2009-2017. All complications were recorded and evaluated. The minimum follow-up was 36 months. Results were statistically evaluated and risk factors for complications were identified. RESULTS: The overall complication rate was 7.3% (67/908 cases), the minor complication rate of 4.9% (45/908 cases) and the major complication rate 2.4% (22/908 cases). The most common severe complications were iatrogenic cartilage damage and instrument breakage, while the most common minor complications were perineal hypoaesthesia and heterotopic ossifications. The conversion rate to total hip replacement was 4.2% (39/908 patients). CONCLUSION: Hip arthroscopy is a safe procedure with low complication rates. Surgeon training and experience greatly influence the complication rates.

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.
