From the Research

If you notice rice-like masses forming around a joint after a joint replacement surgery, this is likely a sign of a serious complication that requires immediate medical attention, as evidenced by a recent case report of exuberant rice body formation associated with adverse local tissue reaction after hip resurfacing arthroplasty 1. These rice-like bodies, called "rice bodies," can indicate infection or inflammatory conditions such as synovitis. The formation of rice bodies is a nonspecific response to chronic synovial inflammation, which can be associated with various conditions, including rheumatoid arthritis, tuberculous arthritis, and osteoarthritis 2.

Key Considerations

  • Contact your orthopedic surgeon immediately or go to the emergency room if you notice any unusual symptoms or masses around the joint.
  • Do not attempt to treat this at home, as prompt medical attention is crucial to prevent further complications.
  • Your doctor will likely need to perform joint aspiration to collect fluid samples for testing, followed by appropriate antibiotic therapy if infection is confirmed.
  • In severe cases, surgical debridement or even revision surgery may be necessary to remove the rice bodies and prevent further damage to the surrounding tissues and the prosthesis itself.

Importance of Early Intervention

Early intervention is crucial to preserve joint function and prevent more extensive damage to the surrounding tissues and the prosthesis itself. A recent case report highlighted the importance of prompt surgical intervention in a patient with extensive flexor tenosynovitis with rice bodies in the wrist, who regained full function of the wrist within 2 weeks after surgery 3.

Conclusion is not allowed, so the answer will be ended here.
