Detailed Description

To analyze the surgical conditions of 64 patients with lateral patella excessive compression syndrome who were surgically treated by Deputy Chief Physician Yang Yuping of the Department of Sports Medicine, Peking University Third Hospital from September 2004 to January 2019. Among them, 24 early cases used the traditional proximal release of the lateral retinaculum (traditional surgical group), and recently 40 cases, after learning from the surgical experience of the early cases, switched to the lateral release of the lateral retinaculum, that is, "L" type Release (new surgery group). The visual analog scale (VAS), Lysholm score, and IKDC knee function subjective evaluation scale (IKDC) score were performed before and after the operation. By analyzing the knee movement scores of patients before and after surgery, the efficacy of the above two operations was judged, and the two groups of postoperative scores were evaluated.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual analogue scale (VAS)
Time Frame: Six months after surgery
VAS is used to evaluate knee function. The higher the score of VAS, the better the recovery of knee function
Six months after surgery
(International Knee Documentation Committee) IKDC knee function subjective evaluation form score
Time Frame: Six months after surgery
IKDC score is used to evaluate knee function. The higher the score of IKDC score, the better the recovery of knee function
Six months after surgery
