PURPOSE OF THE STUDY: The aim of the study is to present a comparison of short-term results of double- versus single-bundle anatomical reconstruction of the anterior cruciate ligament (ACL) using hamstring endons and their fixation with absorbable interference screws. MATERIAL AND METHODS: A total of 110 patients with an isolated ACL lesion and the healthy contralateral knee who met the indication criteria for ACL double bundle reconstruction (TISL, 14 mm; ICNW, 12 mm) were intra-operatively allocated at random to either double-bundle group (DB, n=55) or single-bundle group (SB, n=55). At 12 months after surgery, 97 patients (DB group, n=49; SB group, n=48), comprising 68 men and 29 women, were evaluated; the average age was 29.1 years and the injury-to-surgery interval was 15.9 weeks. Pre- and post-operative subjective criteria involved the IKDC and Lysholm score. Objectively, the occurrence of graft failure, range of motion deficit, return to pre-injury sports activity, side-to-side difference in anterior laxity of both knees in 20° flexion on a GNRB laximeter at an applied pressure of 124 N and 250 N, and pivot shift phenomenon were assessed. RESULTS: No statistically significant difference was found in pre-operative values between the two groups. Post-operatively, there were no significant differences in the occurrence of complete graft failure (p=0.0755; DB group, n=0; SB group, n=3), range-of-motion deficit (p=0.2277-0.9788) or return to pre-operative sports activity (p=0.2322). In the DB group, side-to-side anterior tibial shifts at a pressure of 124 N (medians=1.3 mm and 2.1 mm for DB and SB groups, respectively; p=0.0007) and at a pressure of 250 N (DB group =2.1 mm; SB group = 3.1 mm; p<0.0001) were significantly different from the corresponding values in the SB group. Positive results for the pivot shift test (PST) were significantly less frequent in the DB than the SB group (Chi-square test =0.0112). The SB group patients had a 2.9-times (odds ratio, 2.8704) higher risk of positive postoperative PST results than the DB group patients. In both groups, a comparison of pre- and post-operative criteria showed significant improvement in both the subjective and the objective results. DISCUSSION: The results of this study, in accordance with other authors' conclusions, suggest that the double-bundle technique provides better control over rotational and anterior knee laxity and therefore restores knee biomechanics better. However, other literature data do not confirm any significantly better outcomes of this method. Since only short-term results have been obtained so far, the study will continue because only the long-term results can provide conclusive evidence of an advantage of one technique over the other. CONCLUSIONS: Our study showed significantly better restoration of knee rotational and anterior laxity in the patients undergoing anatomical reconstruction of the ACL by the double-bundle technique. The other evaluated criteria did not differ in relation to the technique used.

PURPOSE OF THE STUDY Calcaneal fractures are frequent injuries which may interfere with the patient's daily activities for a long time. They usually occur as the result of an axial load causing impaction of the talus into the calcaneus. They can also be bilateral. Falls and jumps from height are the most frequent causes. MATERIAL AND METHODS Between August 2005 and December 2011, the method of open reduction and internal fixation (ORIF) with a calcaneal locking compression plate (LCP) was used to treat 98 patients with 114 calcaneal fractures. Of these, 16 were bilateral fractures found in two women and 14 men. In each patient, plain lateral and axial X-ray films of the calcaneus were taken on the day of injury. Computer tomography (CT) scans in the sagittal, transverse and coronary planes were obtained. Based on these, the fractures were classified as type I to type IV according to the Sanders system, the patients with type II and type III calcaneal fractures were indicated for ORIF treatment. The results were evaluated using the Rowe score. RESULTS The most frequent cause of fracture was a fall or a jump from height, which was recorded in 81 patients. Bilateral fractures were found in 16 patients. Of the 98 patients, excellent results were in 31, good in 39, satisfactory in 20 and poor in eight patients, as assessed with the Rowe score. Unilateral fractures achieved excellent results in 28, good in 35, satisfactory in 15 and poor in four patients. The results in bilateral fractures were excellent in three, good in four, satisfactory in five and poor in four patients. Early post-operative complications were recorded in a total of 24 patients, of whom 13 had unilateral and 11 had bilateral fractures. DISCUSSION The Sanders classification based on CT examination is used as an indication scheme in our department. Type II and type III fractures are indicated for ORIF treatment. A calcaneal LCP and an extended lateral approach are preferred. This allows for an almost perfect view of the fracture, an accurate reduction of the subtalar and calcaneocuboid joints and a stable internal fixation. In the patients with bilateral fractures, the occurrence of complications, multiple trauma and associated injuries was significantly higher. Also, they had less satisfactory results than the patients with unilateral fractures. CONCLUSIONS The surgical treatment of intra-articular fractures using open reduction from the extended lateral approach and internal fixation with a calcaneal LCP has achieved good results. CT scans are necessary for the diagnosis, fracture classification and indication for a surgical procedure. The timing of surgery plays a decisive role. Open fractures and fractures associated with severe soft tissue injury are treated urgently, other fractures at an appropriate time. Our results showed a significantly higher rate of complications in the patients with bilateral calcaneal fractures, as compared with the patients with unilateral fractures, as well as less satisfactory outcomes. High-energy trauma resulting in bilateral fractures predisposes to comminuted fractures with dislocation, which leads to more serious damage to subtalar joint function.

PURPOSE OF THE STUDY The study presents a retrospective evaluation of clinical data and arthroscopic findings in a group of our patients with symptomatic knee instability due to a partial tear of the anterior cruciate ligament (ACL). MATERIAL AND METHODS The group included 31 patients diagnosed with symptomatic partial ACL tears, i.e. an isolated tear of the posterolateral (PL) or the anteromedial (AM) bundle. The patients' average age was 26.5 years. A side-to-side difference in ventral knee laxity was assessed using the anterior drawer test and the Lachman test under general anaesthesia before arthroscopy was commenced; rotational knee laxity was evaluated by the pivot shift test. An objective evaluation of side-to-side ventral laxity differences in both knees was performed on the GNRB® arthrometer with an applied pressure of 134 N and 250 N in the conscious patient. During arthroscopic examination, findings on the two ACL bundles were recorded. RESULTS All 31 patients were diagnosed with symptomatic partial ACL tears, of them 22 had a PL bundle lesion and nine had an AM bundle tear. All patients with PL bundle lesions only reported problems in association with pivot sports, and all patients with AM bundle tears had problems regardless of any sports activities. In all patients with isolated AM bundle tears, the lesion was located close to its femoral attachment. In the patients with PL bundle tears, femoral location was found in 68% and tibial location in 32% of the patients. In the patients with partial PL bundle lesions, + and ++ results in the pivot shift test were recorded in 32% and 68% of the treated patients, respectively. The Lachman test showed + and ++ results in 71% and 9% of the patients, respectively. The anterior drawer test had negative results in 87% and positive + results in 13% of the patients. The side-to-side difference on the GNRB arthrometer ranged from 0.4 to 2.3 mm at a pressure of 134 N and from 1.2 to 4.2 mm at 250 N in the patients with isolated PL bundle lesions. In the patients with AM bundle lesions, the results were as follows: pivot shift test, 89% negative. 11% positive +; Lachman test, 56% negative, 44% positive +; anterior drawer test, 89% +, 11% ++; GNRB test, 2.2 to 4.4 mm at 134 N, and 4.3 to 7.1 at 250 N. DISCUSSION The diagnosis of partial ACL lesions, i.e., isolated tears of the AM or the PL bundle, requires accurate knowledge of knee anatomy and its biomechanics. In accordance with other authors our results showed that an arthroscopic examination of both bundles of the ligament as well as knee laxity evaluation under general anaesthesia are most essential for making the definite diagnosis in partial ACL tears. They also confirmed that, in isolated AM bundle lesions, ventral laxity is present more often particularly at a higher degree of knee flexion while, in PL bundle lesions, rotational laxity is more frequent and ranges from 0 to 30 degrees of knee flexion. CONCLUSIONS To make the definite diagnosis of partial ACL tears, patient medical history, clinical knee examination including instability type and degree assessment under general anaesthesia and, most importantly, arthroscopic findings on both ACL bundles are necessary.
PURPOSE OF THE STUDY: In this prospective randomised study, the short-term results of arthroscopic transcapsular iliopsoas tenotomy approached from the peripheral versus the central compartment for internal snapping hip syndrome are presented. MATERIAL AND METHODS: A group of 19 patients (15 women and four men; mean age, 24.3 years) who underwent arthroscopic transcapsular iliopsoas tenotomy for internal snapping hip syndrome in the period between September 2010 and December 2011 were prospectively evaluated. No injury, hip surgery or feeling of hip instability was recorded in their personal histories. Radiographs did not show any dysplasia, retroversion of the acetabulum or cam lesions. The patients were allocated to two groups using sealed envelope randomisation: Group 1 patients (n=10) were treated by tenotomy from the peripheral compartment and group 2 patients (n=9) underwent tenotomy from the central compartment during traction of the lower extremity. The evaluation included pre-operative 3T MRI findings, arthroscopically detected intra-articular lesions, duration of traction and post-operative complications. The pre-operative WOMAC scores were compared with those at one-year follow-up. In comparison of the two groups, the Mann-Whitney exact test was used for WOMAC scores and Fisher's exact test for post-operative complications. Statistical significance was set at a 0.05 level. RESULTS: In comparing post-operative complications, a significant difference (p=0.0468) between the groups was found only for genital paresthesia, which did not occur in group 1. The other differences were not statistically significant. The pre-operative WOMAC scores did not differ significantly between the groups (p=0.79). The post-operative WOMAC scores were significantly higher in group 1 (p=0.02). In each group the change in WOMAC scores was different and was statistically significant in group 1 (p=0.0014). Associated intra-articular hip pathologies, most frequently synovitis of the peripheral compartment, acetabular chondropathy, or labral lesions, were diagnosed in 90% of group 1 patients and in 66.7% of group 2 patients. DISCUSSION: Most of the authors comparing the results of two different ilioproas tenotomy techniques at one-year follow-up did not report any statistically significant differences in WOMAC scores between them. In accordance with the data reported, an increase in the post-operative WOMAC score, i.e., improvement of clinical outcome, was achieved in all our patients and, in group 1, it was significantly higher (p=0.0015), as compared with a similar study by Ilizaliturri. However, further follow-up of the patients and evaluation of long-term results will be necessary. CONCLUSIONS: The technique of arthroscopic ilioproas tenotomy approached from the peripheral compartment resulted in significantly fewer cases of genital paresthesia and provided significantly better clinical outcomes in comparison with tenotomy from the central compartment.

PURPOSE OF THE STUDY Since 2000 arthroscopically-assisted surgery on hip joints has become more widely used. The technique is relatively demanding and should be used only after arthroscopic procedures on other large joints are mastered to perfection. A thorough study on cadaverous specimens should be a prerequisite for adopting it as a routine method. The aim of this study was to evaluate indications for hip arthroscopy as, from the year 2006, this was gradually introduced and more widely used at our department. MATERIAL AND METHODS Forty-two hip joints were assessed out of the 83 hips which had been treated by arthroscopic surgery before the date of evaluation and which had been followed up for at least 2 years. The patient group evaluated consisted of 25 men and 17 women, with an average age of 40.3 years and a range of 21 to 65 years. Patients with a follow-up shorter than 2 years and those subsequently undergoing total hip arthroplasty were not evaluated. Indications for arthroscopic surgery included the presence of intra-articular bodies, labro-cartilaginous lesions and impingement syndromes. Neurovascular disorder affecting the limb and a higher degree of osteoporosis were considered contraindications. The outcome of surgery and its indications were evaluated on the basis of the questionnaire which recorded the patient's objective findings and subjective feelings at 3 and 6 months and then at 1 and 2 years after surgery. RESULTS The average VAS score was 7.83 points before surgery, and 3.87 points at 3 months and 2.01 points at 2 years after surgery. Nearly all patients (98%) reported their willingness to undergo the surgery again. The complications included transient hyperesthesia in the perineal region completely resolved within 4 weeks of surgery in three cases and subcutaneous extravasation after extensive capsulotomy in one patient. It subsided within 48 hours without compartment syndrome development. DISCUSSION A good view allowing for comprehensive exploration of the central as well as peripheral compartments enables us to treat all pathologies, which are manageable by arthroscopic intervention, in one procedure. Patient recovery is faster and the risk of intra- and post-operative complications is lower that in open surgery. The avoidance of extensive capsulotomy and the possibility of leaving the femoral head in place with only minimum distractions and without injury to the ligamen-tum capitis are the most important advantages of this method. Complications were found in 8.4% of the cases, which is in agreement with the literature data. The method can be applied in both the diagnosis and therapy of chronic conditions such as femoroacetabular impingement, as well as in the treatment of post-traumatic conditions ranging from traumatic labral lesions to the correction of incongruence of articular surfaces in acetabular fractures. CONCLUSIONS Arthroscopically-assisted surgery enables us to achieve very good results, but requires appropriate, high-standard facilities and a well-mastered operative technique. It should be adopted as the method of choice for young adults still free of arthritic changes including hip impingement syndrome. Similarly to arthroscopic procedures on shoulders and knees, it is associated with low risk factors, and rapid recovery allows the patient to return soon to normal daily activities.
PURPOSE OF THE STUDY Motion-preservation technologies for spinal disorders have evolved and come into use in the last decade. Three principal systems are currently available: total disc replacement, posterior neutralisation transpedicular system and interspinous implants. The aim of this retrospective study was to evaluate our group of lumbar total disc replacements at a follow-up of 2 years. MATERIAL AND METHODS A total of 42 disc prostheses were implanted in 37 patients. Of these, 31 with 35 artificial discs were followed up for 2 years. There were 11 men and 20 women with an average age of 42.9 years (range, 21 to 61 years). The indication for surgery was lumbar disc pain without radicular syndrome and contraindications included advanced degenerative facet joint disease and obesity with a body mass index over 30. Surgery was carried out through the pararectal retroperitoneal approach. Early and late complications were recorded. The group evaluation was based on radiological outcomes, and VAS and ODI scores reported by the patients at 6 weeks, and 3, 6, 12 and 24 months after surgery. RESULTS The average operative time was 68 minutes (range, 36 to 120 min) for single-level lumbar total disc replacement and 92 minutes (range, 72 to 130 min) for two-level procedures. The average hospital stay was 5.2 days (range, 3 to 12). Both keels of the prosthesis were in the exact center in 25 cases, they were shifted laterally in nine cases up to 2 mm and in one case more than 2 mm. Horizontal rotation of the prosthesis was seen in two patients, but not more than 5 degrees to the left. There was no disc loosening or subsidence, and no acceleration of adjacent segment degeneration. Two patients showed heterotopic ossification. Subjective evaluation was recorded as marked improvement in 15, partial improvement in 11 and no change in five patients. None of the patients reported deterioration. Low back pain assessed by the VAS score had an average value of 66.3 before surgery and 14.1 at 2 years after surgery. The average pre-operative ODI value was 48.9 and that at 2 years post-operatively was 24.5. DISCUSSION Pain relief evaluated by the VAS score in our study is comparable with or slightly better than is reported by the other authors. Some recorded average values for lumbago were 74 before surgery and 35 at 2 years of follow-up, or 62.3 before and 25.4 at 2 years after surgery, while our patients had the average VAS score of 66.3 before surgery and that of 18.4 at 2 years after surgery. The ODI values in our group were similar to those of other authors. When we compare this group with the group of our patients who were treated by spinal fusion surgery, the outcomes at 1 year are better in the total disc replacement group, as shown by the VAS for lumbago of 17.8 and ODI of 24.5 in the former versus the respective values of 18.1 and 29.0 in the latter group. CONCLUSION Based on the results it can be concluded that total disc replacement is an efficient method of treating degenerative inter-vertebral disc disease of the lumbar spine in young, active and motivated patients with no posterior spinal structure degeneration.

PURPOSE OF THE STUDY The aim of the study was to compare two options of how to get the correct anatomical position of both femoral tunnels, using the transtibial or the anteromedial portal technique, during anatomical double-bundle anterior cruciate ligament (ACL) reconstruction. MATERIAL AND METHODS A total of 36 patients, 29 men and seven women, underwent double-bundle ACL reconstruction between October 2009 and December 2010. Their average age was 26.5 years. The average interval between ACL injury and reconstruction was 7.4 months. A diagnostic arthroscopy for the treatment of cartilage and meniscal lesions was performed in 21 patients and one-stage ACL reconstruction with diagnostic arthroscopy was carried out in the remaining 15 patients. In all 36 patients, the position of the tip of the guide wire in relation to the anatomical insertion sites of both the anteromedial (AM) and posterolateral (PL) bundles was assessed intra-operatively. Three guide wire positions were found: the tip was in the centre of the native insertion site, the tip was within the insertion site but not in its centre, and the tip was outside the insertion site. RESULTS Using the transtibial technique through the AM tunnels, the tip of the guide wire was centred within the femoral AM insertion site only in one patient (2.8%), out of the centre but within the AM insertion site in four patients (11.1%) and outside the insertion site in the remaining 31 patients (86.1%). With this technique, the position of the femoral PL tunnels was outside the native PL insertion site in all 36 patients. With the transtibial technique using the PL tunnels, the tip of the guide wire was centred within the femoral AM native insertion in 11 patients (30.5%), out of the centre but still within the AM insertion site in 16 (44.5%) and outside the AM insertion site in nine patients (25%). Aiming for the femoral PL tunnel resulted in the tip of the guide wire being outside the native femoral PL insertion site in all cases. Using the technique of guide wire insertion through an accessory AM portal it was possible to achieve the centres of both the AM and PL native anatomical insertion sites in all 36 patients (100%). DISCUSSION We agree with the many authors who recommend the reaming of PL femoral tunnels through an accessory AM portal because the transtibial technique does not allow for the placement of their precise native anatomical positions. Our intra-operative findings showed that the transtibial technique was effective to get the correct anatomical position of AM femoral tunnels just in 30.5% of the patients. In view of the fact that the same results can be achieved with the AM transportal technique in 100% of the patients, we prefer this technique in accordance with the majority of other authors. CONCLUSIONS In anatomical double-bundle ACL reconstruction, the native anatomical position of PL tunnels was achieved in all patients and the native AM tunnels in most of them using the accessory AM portal technique. The transtibial technique proved to be unsatisfactory.
