Arthroscopic removal of giant loose bodies in the glenohumeral joint

Loose bodies within the joint because of any cause have the potential for continued growth.

A 41-year-old man had suffered multiple recurrent dislocations of his left shoulder, accompanied with pain. His anterior apprehension and relocation tests were positive, but no other sign was noted on physical examination. On magnetic resonance imaging and at arthroscopy, two giant loose bodies were seen. They were in the axillary recess and were removed arthroscopically.

Most authors recommend surgical removal of the cartilaginous loose bodies to ameliorate the symptoms. Furthermore, the majority of authors recommend a synovectomy to decrease the risk of recurrence. Depending on the size of the chondral loose bodies, removal can be performed via an arthrotomy, arthroscopy with mini-open arthrotomy, or arthroscopy.

The source of the loose body should be determined carefully. Other lesions may be associated with the loose body. Arthroscopic treatment is a good option for removing the loose body.
