Shoulder rheumatoid arthritis associated with chondromatosis, treated by arthroscopy

We present a case of rheumatoid arthritis that affected the right shoulder and was associated with chondromatosis and multiple loose body formation. The arthritis was treated arthroscopically with satisfactory results after a follow-up period of 15 months. In our case, arthroscopic debridement and partial synovectomy not only relieved the pain but also improved the range of motion the night after surgery. The multiple loose bodies irritating the synovium and causing effusion, crepitus, and locking were also removed. One may need to change portals of the scope and suction cannula to remove loose bodies in different joint spaces. The subacromial space must be searched for loose bodies. Thorough cleaning, lavage, and synovectomy are important parts of this surgery. The continuous passive motion (CPM) machine in the immediate postoperative period was helpful.
