About this study

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.

Inclusion criteria

  • From September 2004 to January 2019, patients with lateral patella overcrowding syndrome treated by deputy chief physician Yang Yuping of the Department of Sports Medicine, Peking University Third Hospital

Exclusion criteria

  • From September 2004 to January 2019, patients with lateral patella overcrowding syndrome treated by deputy chief physician Yang Yuping of the Department of Sports Medicine, Peking University Third Hospital

Treatment and study plan

"L" type release surgery

Procedure

Lateral release of the lateral support belt

Primary outcomes

  1. 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

  2. (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
