Arthroscopic Arthrolysis and Quadricep VY Plastiy for Post Traumatic / Post Surgical Stiff Knee

Abstract

Objective: We sought to evaluate the effectiveness after combined arthroscopic arthrolysis and quadriceps V-Y plasty in post-traumatic, post infection or post-surgical stiff knee.

Study Design: A descriptive case series study.

Place and Duration of Study: This study was conducted at the Department of Orthopaedic, Traumatology and Sports medicine, MTI, LRH Peshawar from January -2022 to January-2024.

Methods: A total of 30 patients, 18 male and 12 female were operated from January 2021 to January 2024. Active and passive knee flexion and extension were assessed for patients both before and after surgery and the KSS was also used to evaluate function. Data analysis was done on paired t- tests with the statistician setting the level of significance at 0.05.

Results: The mean pre-operative ROM was 50°±8Sd, which was increased to mean 110°±10°Sd at the latest follow up, thus a mean improvement of 80 % (p<0.001). Knee Society Score (KSS) increased from mean 45 ± 10 to 85 ± 8 indicating 88% improvement in the mean score (p < 0.001). Low complication rate was identified whereby 90% of the patients were highly satisfied with the procedure.

Conclusion: The current study shows that arthroscopic arthrolysis together with quadriceps V-Y plasty has a profound beneficial effect on the extension deficit and functional status of the knee in patients with Post-Traumatic Or Post-Surgical Knee Stiffness.
