Comprehensive post-arthroscopic management of a middle-aged adult with glenohumeral osteoarthritis: a case report.

UNLABELLED: Comprehensive Arthroscopic Management (CAM) is a new glenohumeral debridement procedure developed as a joint preserving alternative to total shoulder arthroplasty (TSA). The procedure consists of several arthroscopic components including: A. scar tissue and chondral debridement, B. synovectomy, C. inferior humeral osteoplasty, D. capsular release, E. axillary nerve decompression, and F. tenodesis of the long head of the biceps. In this case, an active, middle age patient who failed physical therapy treatment and corticosteroid injections was evaluated and diagnosed with glenohumeral osteoarthritis. Anterior- posterior (AP) and axillary radiographs showed grade IV changes of the articular cartilage, confirming the diagnosis. The patient was not an ideal candidate for TSA because of her age, activity level, and concern for implant survival; therefore surgical intervention was performed using the CAM procedure. After the surgery, the patient demonstrated increased joint space as shown using radiographic imaging. The patient underwent intensive postoperative rehabilitation with a heavy emphasis on joint range of motion (ROM) and capsular mobility. By eight weeks she achieved 85% active ROM compared to her uninvolved shoulder, and a 55% improvement on the Pennsylvania Shoulder Score. Radiographic imaging provided an understanding of the severity of the arthritic changes present in this patient, identified the limited potential of continued conservative management, and showed structural changes that may be correlated with improved function following the surgical intervention. For patients less than 55 years of age diagnosed with severe glenohumeral osteoarthritis, the CAM procedure and intensive, motion focused therapy presents a promising treatment combination.
