A 27-year-old man presented with painful progressive loss of mobility in the left hip joint. Radiography revealed multiple roundish, lentil-sized periarticular densities with homogeneous calcification. The Figure shows the typical findings of synovial chondromatosis, a disease that is diagnosed more frequently in men (2:1) in the age group of 20 to 40 years. The knee is the joint most commonly affected, followed by elbow, hip, shoulder, and ankle. Biarticular manifestations are extremely rare and usually symmetrical. The pathogenesis is uncertain; maldifferentiation of the joint-forming mesenchyma with transformation of fibroblasts to chondroblasts has been postulated. Open and/or arthroscopic resection of the chondromas is indicated. Synovectomy is recommended to minimize the recurrence rate, however, studies have failed to prove a superiority of surgery over radiotherapy (radiosynoviorthesis/percutaneous irradiation). We performed open removal of the loose joint bodies with partial synovectomy, followed 6 weeks later by radiosynoviorthesis. The patient currently has no symptoms.
