Abstract

Calcification in the tendon is a common disease especially in the rotator cuff. The condition can be treated conservatively in the chronic stage, but surgically in the acute stage. On the other hand there are few reports of calcification in the cruciate ligament of the knee joint, especially calcification of the posterior cruciate ligament. A 51-year-old patient with symptomatic calcification in the mid-substance of the posterior cruciate ligament was treated conservatively. The symptoms did not improve after eight months of conservative treatment, so arthroscopic surgery was performed. During arthroscopic removal of the calcification, the ligament was damaged beyond preservation. Eventually a posterior cruciate ligament reconstruction was performed. At two years after surgery, radiography confirmed no recurrence of the calcification, and the patient was free. We report this case study with a review of the relevant literature.
