Background: Synovial chondromatosis often occurs in the knee, followed by the hip, elbow, and shoulder. Synovial chondromatosis is an uncommon, benign condition of the synovial tissue. Early treatment is necessary to help relieve painful symptoms. At a later stage, it can lead to joint arthritis. Materials and Methods: Arthroplasty with simultaneous synovectomy was performed in patients with synovial chondromatosis with an arthritic hip. The posterior approach was taken in all the cases, and patients followed up at 1 month, 2 months, 6 months, and annually thereafter till now.

Results: Large wedged clumps of loose bodies demonstrated, histologically confirmed. At the latest follow-up, the entire patient remains symptom-free with no radiographic evidence of recurrence.

Conclusions: Arthroplasty with simultaneous synovectomy in the arthritic hip of synovial chondromatosis provides reliable pain relief and excellent disease-specific survival at long-term follow-up.
