Use of Hyaluronic Acid Injection in Lateral Patellar Compression With Femoral Condylar Degenerative Changes After Arthroscopic Release

Ninety patients are involved in this study, who underwent arthroscopic lateral patellar release for lateral patellar compression syndrome and they had patellofemoral degenerative lesion, which diagnoses by MRI preoperatively and proved by arthroscopic examination to be early stages of degenerative changes with no loss of articular surface. The patients were divided in to two groups (A and B). Group A (45 patients) were treated by local injection of Hyaluronic acid intraarticularly, and Group B (45 patients) were no injection intraarticular.
