Objective: To investigate the method and effect of arthroscopic lateral patella retinaculum releasing (LPRR) either through or outside synovial membrane for the treatment of lateral patellar compression syndrome (LPCS).
Methods: From September 2014 to December 2017, 125 patients with LPCS underwent arthroscopic LPRR either through or outside synovial membrane combined with joint debridement. In the outside synovial membrane (OSM) group, synovial membrane was retained. In the through synovial membrane (TSM) group,The synovial membrane was cut open. Active rehabilitation training was conducted after surgery. Before and after surgery, Lysholm score, patella medial shift, Kujala score, VAS score and surgical complications were evaluated and compared.
Results: All patients in this study were followed up for 1.5-5 years. All patients had significant reduction in knee pain and improved function after 1 month and 1 year. The Lysholm score, the distance of patella medial shift, the Kujala score, and the VAS score in the OSM group and the TSM group were significantly improved in the final follow-up compared with before surgery ( P <0.001), but these observed targets before surgery and at the last follow-up between the two groups were compared with no statistical differences. However, the number of occurrences of joint hematoma and adhesion was significantly higher in the TSM group than the OSM group ( P =0.024).
Conclusion: Arthroscopic closing LPRR for the treatment of LPCS can effectively improve the function and symptoms of the patellofemoral joint with the advantages of small trauma, rapid recovery and less complications. But, the number of occurrences of hemarthrosis and joint adhesion in the TSM group were significantly higher than those in the OSM group.
