Arthroscopic posteromedial capsular release for knee flexion contractures

Area of Science:

• Orthopedic Surgery
• Knee Biomechanics
• Minimally Invasive Procedures

Background:

• Knee extension deficits limit function post-surgery or injury.
• Current treatments include manipulation, debridement, and open capsular release.
• Arthroscopic posteromedial capsular release for flexion deficits lacks comprehensive study.

Purpose of the Study:

• To evaluate the efficacy of arthroscopic posteromedial capsular release for knee extension deficits.
• To assess improvements in knee motion following the procedure.

Main Methods:

• A review of 15 patients undergoing arthroscopic posteromedial capsular release.
• Measurement of passive knee extension and flexion using a goniometer.
• Data collected preoperatively, immediately post-release, and at final follow-up (average 24.1 months).

Main Results:

• Preoperative knee extension averaged 14.7 degrees, improving to -0.9 degrees immediately post-op and 0.7 degrees at final follow-up.
• Average range of motion improved from 101.6 to 129.4 degrees.
• The procedure demonstrated significant gains in knee extension and overall motion.

Conclusions:

• Arthroscopic posteromedial capsular release is effective for treating knee extension deficits.
• The procedure offers comparable results to open posterior capsular release studies.
• This technique provides a viable option for symptomatic knee extension deficits.
