Introduction Knee dislocations are uncommon but serious injuries. These injuries not only pose a potential threat to the limb involved, but often result in long-term pain and functional disability. What was thought to be an injury pattern caused by high-energy…
Introduction The concept of a dislocated knee has changed markedly over the past few decades. In 1971, Meyers and Harvey predicted that most orthopedists would not see more than one knee dislocation in their entire career. However, evidence indicates that…
Clinical Concepts Medial ligament injuries are among the most frequently treated problems of the knee joint. Whereas isolated superficial medial collateral ligament (SMCL) ruptures are common, concomitant damage to the anterior cruciate ligament (ACL) occurs in many cases, especially in…
Indications Medial ligament injuries are among the most frequently treated problems of the knee joint, with the majority not requiring operative intervention. Whereas isolated superficial medial collateral ligament (SMCL) ruptures are common, concomitant damage to the anterior cruciate ligament (ACL)…
Clinical Concepts Critical Points Clinical Concepts Protocol for posterior cruciate ligament reconstruction for procedures with high-strength two-strand graft (quadriceps tendon-bone, bone-patellar tendon-bone). Progress patient on athletic and occupational goals, condition of the articular surfaces and menisci, return muscle function, postoperative…
Indications Critical Points Indications 6- to 10-mm increased lateral tibiofemoral joint opening 20 degrees of flexion. ≥15 degrees increased external tibial rotation 30 degrees, 90 degrees of flexion. ± Varus recurvatum, standing and supine. ± Hyperextension gait abnormality. Double or…
Indications Critical Points Indications Mechanism of injury, low versus high velocity. Complete PCL rupture usually associated with other ligament injuries. Isolated PCL rupture represents serious injury, chance of functional deterioration, arthritis over time. Indications for chronic isolated complete PCL rupture:…
Introduction This chapter provides a summary of the important biomechanic principles gained from our publications and other investigations regarding the posterior cruciate ligament (PCL) and posterolateral structures (PLSs). The primary PLSs of the knee joint are the fibular collateral ligament…
Scientific Rationale and Supporting Investigations for Sportsmetrics Neuromuscular Retraining Program This chapter presents the scientific rationale, supporting data, and specific strategies for the implementation of Sportsmetrics, a neuromuscular knee ligament injury prevention training program. Since Sportsmetrics was first introduced to…
Video Content Video 11-4 Sportsmetrics Neuromuscular Conditioning Programs to Prevent ACL Injuries in Female Athletes Introduction It is well recognized that female athletes and military recruits have a higher incidence of noncontact anterior cruciate ligament (ACL) injuries than males participating…
