Fanelli GC, Larson RV. (OBQ10.139) A 37-year-old male presents with continued knee pain and instability 6 months status-post combined ACL and PCL reconstruction after a traumatic knee injury. Although rare, posterolateral corner (PLC) injuries can result in sustained instability … 1991(264):235-8. On physical exam his ACL and PCL are intact, however he is noted clinically to have Grade 3 posterolateral corner laxity and varus malalignment of his knee. Isolated posterolateral rotatory instability of the knee is an uncommon injury pattern that may result in significant degrees of functional disability. The treatment for posterolateral rotatory instability is surgical. Loomer RL. Tests: See Knee … Acute posterolateral rotatory instability of the knee. The anatomy, biomechanics, imaging appearances, and injury patterns of the posterolateral corner of the knee are described in this review article. An attempt to reattach or … J Bone Joint Surg Am 1983;65(5):614–618. Abstract: The anterolateral complex (ALC) of the knee plays an important role in rotatory knee stability, especially in anterior cruciate ligament (ACL)-deficient patients. associated with knee dislocation (see below) Posterolateral injury components.

Posterolateral rotatory instability of the knee, a poste rior rotational subluxation of the lateral tibial plateau in relation to the lateral femoral condyle, is an unusual condition. POSTEROLATERAL INSTABILITY = when stress testing the lateral tibial plateau rotates posteriorly in relation to the femur with lateral opening of joint . The goal of surgery is to restore stability to the elbow and eliminate pain, without limiting motion.
