Bilateral knee synovial chondromatosis with osteoarthritis - A case report

Abstract

Synovial chondromatosis is a rare, benign metaplastic condition that typically affects the synovial membrane of large joints, such as the knee, hip, shoulder, and elbow. This case report presents a 67-year-old male with bilateral knee osteoarthritis complicated by synovial chondromatosis, who underwent total Knee Replacement (TKR). The patient presented with progressive pain, swelling, and limited range of motion in both knees over two years. X-ray imaging revealed multiple radiodense loose bodies in both knees, and histopathological examination confirmed the diagnosis of synovial chondromatosis. Treatment involved removal of the loose bodies and synovectomy during TKR. Postoperative follow-up showed no recurrence of loose bodies after one year. This case highlights the challenges of diagnosing and treating synovial chondromatosis, particularly when it coexists with advanced osteoarthritis, and underscores the importance of comprehensive treatment for improving patient outcomes.
