The purpose of this study was to determine the anatomy of the posterolateral aspect of the rabbit knee to serve as a basis for future in vitro and in vivo posterolateral knee biomechanical and injury studies. Twelve nonpaired fresh-frozen New Zealand white rabbit knees were dissected to determine the anatomy of the posterolateral corner. The following main structures were consistently identifie...

Posterolateral knee injuries can be very debilitating. It is important to understand the complex anatomy and pertinent diagnostic tests to properly treat posterolateral knee injuries. The fibular collateral ligament, popliteus tendon, and the popliteofibular ligament are the main static stabilizers against abnormal varus and posterolateral translational moments. Important radiographic imaging s...

We used the MacIntosh over-the-top repair combined with a popliteal tendon plasty in 273 athletically active patients with chronic incapacitating functional instability due to anterior cruciate ligament rupture; 244 were reviewed at three to nine years after operation. We describe the technique and its results, with functional evaluation by the Tegner and Lysholm system. Excellent or good resul...

Chronic Lateral Collateral Injuries Lateral collateral ligament (LCL), popliteus tendon and popliteo-fibular ligament (PFL) are the main static stabilizers on the lateral side of the knee and resist abnormal varus and external rotation. Isolated injuries of the lateral stabilizing structures are rare and most of the injuries are associated with damage to the ACL or PCL. Unrecognized posterolate...

We have quantitatively documented the insertion geometry of the main stabilising structures of the posterolateral corner of the knee in 34 human cadavers. The lateral collateral ligament inserted posterior (4.6 mm, sd 2) and proximal (1.3 mm, sd 3.6) to the lateral epicondyle of the femur and posterior (8.1 mm, sd 3.2) to the anterior point of the head of the fibula. On the femur, the popliteus...

OBJECTIVE The aim of this study was to evaluate the treatment of patients with chronic lesions in the posterolateral corner of the knee with reconstruction of the fibular collateral ligament, popliteus tendon and popliteofibular ligament and with autografts of the biceps femoris and fascia lata. METHOD A total of 129 patients with injuries of the posterolateral corner of the knee that lasted ...

Cyamella, an accessory sesamoid ossicle of the popliteus in the region of the proximal myotendinous junction, is an extremely unusual finding, with a paucity of current published literature describing its MR appearance. In this case study, we describe MRI findings in a 44-year-old female presenting with pain after a stretching workout. Bone edema in the cyamella, edema in the myotendinous porti...

The structures in the posterolateral corner of the knee, which stabilize the joint, are often involved in injuries to the posterior cruciate ligament. Familiar structures include the anterior cruciate ligament, posterior cruciate ligament, tibial collateral ligament, and menisci. Less familiar are the structures of the posterolateral corner, the most important of which are the fibular collatera...
