Injury to the posterior cruciate ligament: biomechanics, diagnosis, treatment and prevention of secondary osteoarthritis

Abstract

The literature was reviewed for reports on the pathogenesis, diagnosis and treatment of injuries to the posterior cruciate ligament (PCL). PCL is the largest intra-articular ligament in the knee joint and has good tensile mechanical properties. Optimal diagnosis and appropriate treatment strategies for PCL injury are discussed. Nonoperative treatment of isolated PCL injuries is associated with a significant risk of degeneration of the knee structures and impaired function. A comprehensive line of PCL reconstruction options are offered for the surgical approach to PCL reconstruction to restore functional joint stability in the knee. Literature data on protective effect of glucosamine, chondroitin sulfate in the prevention of secondary knee osteoarthritis caused by PCL ruptures were reviewed.
