D Diagnose: Linke Schulter mit symptomatischer bifokaler Knorpel- läsion und freien Gelenkkörpern

Abstract Common causes of shoulder pain in young-er patients are glenohumeral instability, in-stability of the long biceps anchor (SLAP) or rotator cuff lesions. In the present case of an amateur throwing athlete a bifocal, gleno-humeral osteochondral lesion produced pro-gressive shoulder pain. Multiple arthroliths found during arthroscopy may be signs of a traumatic origin. The osteochondral defects were addressed by a two-stage intervention including microfracture of the glenoid and matrix-associated autologous chondrocyte transplantation of the humeral head.
