A Stepwise Approach to Arthroscopic Management of Recalcitrant Knee Arthrofibrosis Including Arthroscopic Posterior Capsular Release

Arthrofibrosis of the knee is a difficult-to-manage complication after meniscoligamentous knee injuries, traumatic injuries with articular extension, and surgeries to treat these conditions. Treatment protocols for the management of postoperative arthrofibrosis exhaust nonoperative therapies before proceeding to the operating room for lysis of adhesions (LOA). Although LOA restores range of motion in most cases, a recurrence of arthrofibrosis is possible when postoperative therapy protocols are not strictly followed. Limited treatment options exist in the setting of recalcitrant arthrofibrosis. Revision arthroscopic LOA may be performed in this scenario. This revision procedure places neurovascular anatomy in the posterior compartment at risk. Performing a posterior capsule release in the arthroscopic management of recalcitrant arthrofibrosis is challenging but important to optimize recovery of range of motion. This Technical Note and accompanying video present a stepwise approach to LOA that demonstrates a safe method for performing an arthroscopic posterior capsule release in these challenging cases.
