Introduction Anterior cruciate ligament (ACL) tears are a common knee injury, with a reported estimate of 200,000 ACL injuries annually in the United States. Annual ACL reconstruction rates have been reported to be increasing in the United States, with recent…
Introduction Most rehabilitation programs for patients who have undergone anterior cruciate ligament (ACL) reconstruction include exercises and drills that are directed toward improving neuromuscular function and coordination. They are often loosely referred to as proprioceptive training exercises. This chapter explores…
Introduction The primary goal of anterior cruciate ligament reconstruction (ACLR) is to restore stability without sacrificing mobility or strength. The primary purpose of ACLR rehabilitation is to restore mobility and strength without sacrificing stability. It is the central hypothesis of…
Introduction Rehabilitation with anterior cruciate ligament (ACL) reconstruction has evolved considerably since the 1970s, when intra-articular ACL reconstructions were first being performed. We have evolved from using casts on the leg for 6 weeks after surgery to no immobilization at…
This chapter describes the devices, methods, and approaches used to measure anterior cruciate ligament (ACL) strain in vivo, and provides insight into the strain behavior of the normal ACL during various rehabilitation activities. The effectiveness of functional knee bracing on the…
Introduction and Pathophysiology Anterior cruciate ligament (ACL) rupture is commonly associated with osteoarthritis (OA) of the knee. There are two pathologies to ACL rupture in knee OA. ACL rupture can be secondary to primary OA, or it can be the…
Introduction Knee joint intra-articular ganglion cysts may originate from the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), menisci or meniscal tears, popliteus tendon, alar folds, or areas of chondral fracture in descending order of frequency. Although the term ganglion…
Introduction Bone contusions of the knee refer to bone injuries seen on magnetic resonance imaging (MRI) and are also referred to as bone bruising and bone marrow edema. These lesions likely depict hemorrhage, edema, or infarction resulting from trabecular microfractures.…
Introduction Posterolateral knee injuries have been noted to be some of the most difficult knee injuries to diagnose and treat due to the multiple different structures, the intricate anatomical relationships, and the fact that there is no one specific clinical…
