Surgical treatment of posttraumatic arthritis of patellofemoral joint

Introduction: Posttraumatic arthritis of the patellofemoral joint is a serious medical problem, especially among young and middle-aged people and active athletes. According to various studies, the incidence of posttraumatic changes in the patellofemoral joint ranges from 10% to 40%, which confirms the relevance of surgical treatment. Objective: to improve the results of surgical treatment of post-traumatic osteoarthritis of the patellofemoral joint with lateral patellar hyperpression using arthroscopic lateral patellar release. Materials and Methods: Fifty-four patients aged 20 to 70 years (M±σ 50.7±13.3 years) with lateral patellar hyperpressure syndrome participated in the study. Patients were divided into 2 groups: 39 patients who underwent surgical treatment and 15 patients who were treated conservatively. All patients were questioned using the VAS and KOOS scales. Results: The VAS scale score in group 1 patients had a faster decrease in pain score in dynamics (from 6,5 to 1,56; 74%) compared to that in group 2 patients. Total KOOS scale score in patients of group 1 in dynamics increased in earlier terms (from 36,12 to 80,09; 121,73%) in comparison with the index of patients of group 2. By the end of follow-up in both groups, statistically reliable improvement of VAS and KOOS scores was noted. Surgical intervention, including dissection of the lateral supporting ligament of the patella, provided faster pain relief (VAS score) and improved functional status with increased activity levels (in daily life and sports) and quality of life (KOOS score) compared with conservative treatment. Conclusion: The analysis of the results of surgical treatment of post-traumatic patellofemoral joint arthritis showed positive outcomes and a significant improvement in the clinical indicators of the knee joint, as well as a reduction in pain levels at earlier stages compared to conservative treatment.
