PURPOSE: Treatment outcomes of conservative and surgical treatment of Legg-Calvé-Perthes disease (LCPD) have been shown to be conditioned by a number of factors that may vary across different populations. This retrospective study aimed to evaluate factors affecting radiographically assessed treatment outcomes in patients treated surgically or conservatively for LCPD at Faculty Hospital Motol, Prague, Czech Republic, between the years 2006 and 2019. METHODS: Data of forty-seven children comprising 52 hips were analysed. Treatment outcomes were evaluated according to Stulberg classification. Predictors included the initial stage of fragmentation of the hip joint according to Herring classification, type of treatment (conservative or surgical), age at the time of diagnosis and sex. RESULTS: Older age and severity of LCPD according to Herring classification but not the type of treatment were the strongest factors determining treatment outcomes. Treatment outcomes were comparable in patients treated conservatively or surgically both across the whole cohort of patients and a group of young children < six years of age. CONCLUSIONS: Results strengthen the roles of severity of the LCPD at onset of treatment and age of the patient in predicting treatment outcomes in patients with LCPD. Conservative and surgical treatments appear to yield similar treatment outcomes irrespective of age of patients.

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: To establish recommendations for diagnosis, classification, treatment, and rehabilitation of posteromedial corner (PMC) knee injuries using a modified Delphi technique. METHODS: A list of statements concerning the diagnosis, classification, treatment and rehabilitation of PMC injuries was created by a working group of four individuals. Using a modified Delphi technique, a group of 35 surgeons with expertise in PMC injuries was surveyed, on three occasions, to establish consensus on the inclusion or exclusion of each statement. Experts were encouraged to propose further suggestions or modifications following each round. Pre-defined criteria were used to refine item lists after each survey. The final document included statements reaching consensus in round three. RESULTS: Thirty-five experts had a 100% response rate for all three rounds. A total of 53 items achieved over 75% consensus. The overall rate of consensus was 82.8%. Statements pertaining to PMC reconstruction and those regarding the treatment of combined cruciate and PMC injuries reached 100% consensus. Consensus was reached for 85.7% of the statements on anatomy of the PMC, 90% for those relating to diagnosis, 70% relating to classification, 64.3% relating to the treatment of isolated PMC injuries, and 83.3% relating to rehabilitation after PMC reconstruction. CONCLUSION: A modified Delphi technique was applied to generate an expert consensus statement concerning the diagnosis, classification, treatment, and rehabilitation practices for PMC injuries of the knee with high levels of expert agreement. Though the majority of statements pertaining to anatomy, diagnosis, and rehabilitation reached consensus, there remains inconsistency as to the optimal approach to treating isolated PMC injuries. Additionally, there is a need for improved PMC injury classification. LEVEL OF EVIDENCE: Level V.

PURPOSE: Arthroscopy of the hip joint is considered a demanding procedure with long learning curve. There are only a few studies that concentrate on this topic. This prospective clinical study evaluates the learning curve of the hip arthroscopy based on clinical outcomes, surgical time, and complication rate. MATERIALS: In this study, we first evaluated 150 hip arthroscopy procedures performed by a single surgeon. The patient group consisted of 86 females and 64 males with mean age 37 years (range 16-69). Study cohorts were divided into groups of 50 patients. Surgical time, complication rate and clinical results based on NAHS score were recorded for each group. Statistical analysis of differences between groups was performed using the ANOVA method and paired t-test. RESULTS: We found a statistically significant decrease of complication rate with more procedures performed. There were significantly better clinical outcomes after at least 100 procedures. No difference in surgical time was found, but towards the end of the learning curve, more complex procedures were performed. The only statistical difference was the portal setup time. The learning curves were constructed based on these results. CONCLUSIONS: Hip arthroscopy provides very good clinical outcomes if precisely indicated and performed. It is, however, a demanding procedure with many possible pitfalls and complications. According to our study, at least 100 procedures are needed to gain basic technical and indication skills. The presence of a more skilled surgeon in the beginning of the learning curve is advised to reduce the complication rate.

Femoroacetabular impingement syndrome is a very common hip pathology that is responsible for hip pain in patients under 40 years of age. Anatomic changes in hip joint cause labral tears and cartilage dysfunction, both of these conditions cause severe hip pain and often lead to hip arthritis. This syndrome is very common in the population, but very often misdiagnosed and undertreated.The main treatment option is surgical treatment; conservative treatment alone is not successful. There are many surgical procedures that may be chosen according to the degree of hip pathology. In this article we present treatment options for femoroacetabular impingement syndrome and our results. Recently one of the main treatment options is hip arthroscopy we have very good experience and results with this method.

PURPOSE: The incidence of an anterior cruciate ligament (ACL) tear is highest in female patients; however, it is not apparent whether graft choice affects clinical results. The aim of this prospective randomised study was to evaluate clinical results of an ACL reconstruction using patellar tendon [bone-patellar tendon-bone (BTB)] or hamstring graft (HS) in female patients. METHODS: Inclusion criteria were traumatic instability, no signs of osteoarthritis, no previous instability and no contralateral knee instability. Inclusion criteria were met in 150 patients, mean age 26 (17-47) years. Patients were randomised into two groups of 75 patients according to graft type; all had the same rehabilitation protocol. Tegner Lysholm knee score and stability were evaluated pre-operatively and one and two years postoperatively. The difference between groups was statistically evaluated using unpaired t test. RESULTS: Of the 150 patients, all completed one year follow-up; three were lost to follow-up at two years. There was no significant difference in functional scores and knee stability between groups. The HS group had significantly less anterior knee pain in the first six months postoperatively. CONCLUSION: ACL reconstruction significantly improves clinical results and stability of the knee. Difference in Lysholm score and stability between groups was not significant. Neither group showed higher tendency to graft failure within two years. Graft choice for reconstruction in female patients should be surgeon specific and individualised, as both grafts studied achieved comparable results.

PURPOSE: Avulsion fracture of the anterior-superior iliac spine is an uncommon injury. It is mostly seen in adolescent sprinters, distance runners and soccer players. Most cases are unilateral. We present a cohort of patients and the strategy for their treatment. METHODS: During the period 2005-2012, we treated 23 (19 male, four female) patients with an average age of 15.1 years (4-17). Ten patients with minimally displaced fractures were treated conservatively, and 13 patients with greater fragment dislocation were treated surgically. All patients underwent the standardised rehabilitation protocol. We evaluated range of motion (ROM), X-ray six weeks and one year postoperatively, length of bed rest, return to activity and complication rates (infection, heterotopic ossification). RESULTS: All patients returned to sports at the preinjury level. Surgically treated patients showed faster recovery and better compliance with rehabilitation protocols. The time interval for X-ray union was comparable between groups, as was full recovery. There was no deep infection; however, there were five minor heterotopic ossifications, none of which required further treatment. CONCLUSION: We emphasise that the indication for surgical treatment is mainly determined by the grade of fragment displacement and the patient's sporting activity. Although long-term results were comparable between treatment methods, surgery carries the risk of higher complication rates and the need for osteosynthetic material extraction.

PURPOSE: The aim of the present study was to introduce a novel oblong revision cup type TC for use in revision total hip arthroplasty (THA), and to evaluate mid-term results in terms of bone tissue remodelling in the immediate area of the implant. METHODS: The results of 31 patients that underwent revision THA between 2004 and 2008 are presented. The mean follow-up interval was 7.1 years (range 5.3-9.3 years, minimum of five years following revision). Osteointegration of the implant and bone tissue remodelling around the implant and ribs were assessed by X-ray and computed tomography (CT). RESULTS: The average Harris hip score increased from 39.8 to 85.3. Excellent results were achieved in nine patients, good in 16, fair in three and poor in three. According to X-ray results, 25 hips had a well-fixed, bone-ingrown cup and five had a stable fibrous union in the middle and the distal third of the implant. Proximal migration of the cup was noted in one case. Pelvic CT was additionally performed in ten patients. In all cases, we detected bone remodelling in the space between the implant ribs. Kaplan-Maier survivorship of the acetabular components was 94.2 % at 7.1 years. CONCLUSIONS: Our results show that the novel oblong revision cup type TC is relatively simple to implant, and is associated with reliable primary fixation and documented osteointegration and bone remodelling in the immediate area.

OBJECTIVE: Improved staging of cartilage degeneration is required, particularly during the early stages. We correlated mechanical properties with histological and macroscopic findings. METHODS: One hundred and twenty cartilage samples were obtained during total knee arthroplasty. Two adjacent plugs were harvested--one for histological classification and one for macroscopic and biomechanical purposes. Dynamic impact testing was performed; normal stress, dissipated energy (∆E), tangent modulus and stiffness were evaluated. RESULTS: Samples were classified according to six categories of the ICRS histological scale. Mechanical characteristics revealing significant differences between the groups (p < 0.01) were specific damping and related absolute ∆E. A significant correlation was found between the macroscopic score and specific damping, as well as absolute and relative ∆E (p < 0.01). A strong relation was revealed between relative ∆E and cartilage thickness (p < 0.001; R (2) = 0.69). CONCLUSIONS: Only ∆E correlated with the condition of the cartilage--the value increased with decreasing quality-and is the most suitable characteristic. This change appears substantial in initial stages of cartilage deterioration.

BACKGROUND: Rotator cuff tear--diagnosis; comparison of MRI, ultrasonographic and arthroscopic findings. MATERIALS AND METHODS: Retrospective study--20 patients treated for shoulder pain due to rotator cuff tear, initially conservatively and after more than 6 months by arthroscopic shoulder surgery. Comparison of intraoperative findings with preoperative US and MRI images. RESULTS: Sensitivity of USG--1.0, specificity 0.9. Sensitivity of MRI--0.92, specificity 1.0. DISCUSSION: Clinical examination and physical tests are not fully reliable diagnostic tools in patients with shoulder pain, because symptoms of different conditions overlap. Using ultrasound to visualize the shoulder area has some advantages to other imaging techniques such as CT scan or MRI, and has a very good sensitivity and good specificity. Many authors agree that MRI is one of the most effective methods for the diagnosis of rotator cuff tear. CONCLUSIONS: Ultrasound and magnetic resonance imaging are both very sensitive techniques for diagnosis of rotator cuff abnormalities. Ultrasonography can be used as a primary method owing to its fast procedure and affordable cost.
