The Clinical Effect of Different Lateral Retinaculum Relaxation Methods in the Treatment of LPCS

Completed

• Conditions: Lateral Patellar Compression Syndrome
• Interventions: Procedure: "L" type release surgery

• Registration Number: NCT04958603
• Lead Sponsor: Peking University Third Hospital

Brief Summary

To observe the comparison of the clinical effects of two different ways of loosening the lateral support band under arthroscopy to treat lateral patella excessive compression syndrome.

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.

Group	Intervention	Description
New surgery group	"L" type release surgery	Laterally loosen the outer support belt, that is, "L"-shaped loosen

Primary Outcome Measures

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