Surgical Treatment of Chronic Posteromedial Instability Using Capsular Procedures.

The article reports on the surgical treatment of chronic posteromedial instability using capsular procedures. Anteromedial rotatory instability symptoms are often overlooked due to concurrent anterior cruciate ligament and posterior cruciate ligament injuries. Unrecognition and nontreatment of the damage results in residual functional laxity and may lead to chronic and progressive instability of the knee. Two surgical techniques addressing posteromedial instability that requires an understanding of posteromedial corner knee anatomy, careful preoperative planning, and extensive postoperative rehabilitation are discussed.
