Mucoid Degeneration of the Posterior Cruciate Ligament: A Case Report of a Rare Condition.
Main Article Content
Abstract
Mucoid degeneration of the cruciate ligament can occasionally result in knee pain and restriction in range of motion. A 45-year-old female presented to the outpatient department complaining of pain in her right knee joint when she extended it to its fullest extent. The range of motion (ROM) was 10 degrees of flexion contracture, with forced extension exacerbating the pain. Posterior cruciate ligament (PCL) mucoid degeneration was detected in the knee on magnetic resonance imaging. The procedure of arthroscopic treatment involves PCL reduction, which lowers the volume of the hypertrophied PCL by debridement of yellowish material in the PCL fibres. After surgery, the patient regains full range of motion without experiencing any impingement symptoms. Enlarged PCL can lead to an impingement in the femoral notch with the anterior cruciate ligament (ACL). According to previously published literature on PCL mucoid
