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.
Ten nonpaired cadaveric knees were tested in the intact, superficial medial collateral ligament and posterior oblique ligament–sectioned, and anatomically reconstructed states.
Although acromioclavicular joint separations are fairly common, the occurrence of high-grade acromioclavicular separations that require surgery is low. Various modifications of the Weaver-Dunn procedure have been popular and fairly successful methods to treat severe acromioclavicular separations, despite the fact that reconstructions have been done a number of ways. We […]
Femoroacetabular impingement (FAI) is becoming a prevalent overuse injury diagnosis among hockey players. In the adult ice hockey stride, the ‘‘at-risk’’ hip position, defined by internal rotation during flexion and external rotation during abduction, reportedly increases hip vulnerability to labral injury as a result of FAI.
Stress radiography provides an objective tool to measure posterior knee instability. Intraobserver and interobserver reliability has been reported for the Telos device, but it has not been studied using the kneeling technique.
Bilateral knee dislocations seldom occur, and fewer than a dozen cases of bilateral luxatio erecta humeri (erect dislocation of the shoulder) have been reported.
All-inside meniscal repairs using bioabsorbable repair devices have been a new tool for orthopaedic surgeons in the treatment of meniscal tears.
Common peroneal nerve injury caused by suture entrapment is a complication of arthroscopic inside-out lateral meniscus repair. In the literature, the treatment of this complication has been described as immediate reexploration. We present a case of recovery after late neurolysis performed 7 months postoperatively for a common peroneal nerve neuropraxia. In addition to describing return of function after […]
To determine whether untreated grade 3 posterolateral knee injuries contribute to a significant increase in force on a posterior cruciate ligament reconstruction graft, we measured the force on the graft during joint loading of a posterior cruciate ligament-reconstructed knee with otherwise intact structures and then selectively cut the popliteofibular ligament, popliteus tendon, and the fibular collateral ligament. A posterior cruciate ligament reconstruction […]
Surgical approaches to repair or reconstruct the medial knee structures note caution to avoid the sartorial branch of saphenous nerve.
