Symptomatic Mid-Substance Posterior Cruciate Ligament Calcification of the Knee Joint

Isolated posterior cruciate ligament calcification.

The authors present a case of calcified posterior cruciate ligament (PCL). A 61-year-old female presented in our department reporting 12 months history of knee pain that was getting worse during the night. The patient was under medication for epileptic seizure, osteoporosis and hyperthyroidism. X-rays demonstrated calcification of the PCL. CT and MRI excluded any other intra-articular and extra...

Posterior cruciate ligament injuries of the knee joint.

Posterior cruciate ligament (PCL) injuries have a reported incidence of between 3 and 37%, depending on the clinical setting. The most common mechanism of injury in motor vehicle accidents is a dashboard injury or direct force to the proximal anterior tibia. Sports related injuries result from hyperflexion of the knee with the foot typically plantarflexed. The latter mechanism is the most commo...

Rupture of the posterior cruciate ligament of the knee.

Injury to the posterior cruciate ligament of the knee joint is believed to be uncommon except in association with severe general ligament rupture and dislocation of the knee joint. The isolated injury has been described in the literature, however, in particular by Abbott, Saunders, Bost and Anderson (1944), though no large series has been reported. This paper is based on seventeen cases seen fr...

The posterior cruciate ligament during flexion of the normal knee.

The posterior cruciate ligament (PCL) was imaged by MRI throughout flexion in neutral tibial rotation in six cadaver knees, which were also dissected, and in 20 unloaded and 13 loaded living (squatting) knees. The appearance of the ligament was the same in all three groups. In extension the ligament is curved concave-forwards. It is straight, fully out-to-length and approaching vertical from 60...
