Osteochondral masses encircling the patellar tendon are very rare. A 70-year-old man presented with a complaint of a slow-growing painful mass of 11-year history in the anterior region of the left knee. Computed tomography showed a lesion encircling the patellar tendon. The mass was excised totally. A diagnosis of extraarticular type of synovial osteochondromatosis was made upon synchronous evaluation of clinical, radiological, and histopathological findings. The patient had no complaint other than minimal pain at his last follow-up 40 months after surgery.
