Abstract
Treatment of OA of the shoulder in young and active patients remains a problem. Present treatment options are debridement, microfracturing, arthrodesis or shoulder replacement. We report the preliminary results of soft-tissue interposition arthroplasty with an acellular allograft skin-derived collagen matrix (Graft Jacket®, Wright Medical).
Between July and December 2003 five men and one woman with severe glenohumeral OA had a soft-tissue interposition arthroplasty of the shoulder. The mean age of the patients was 47 years (34 to 58). In four patients the procedure was done arthroscopically. The Graft Jacket® was sutured to the labrum with a minimum of five sutures. The mean postoperative follow-up was 6.2 months.
Four patients experienced notable pain relief after the operation. Preoperatively the mean visual analogue pain score was 7.2 and postoperatively it was 2.6. One patient had no improvement and elected to wait before having further treatment. One patient needed a hemi-arthroplasty. The range of motion improved in only one patient. The mean Constant score improved 14 points, from 45 to 59. There were no complications peroperatively or postoperatively.
While the long-term results are still unknown, soft-tissue interposition arthroplasty with the Graft Jacket® shows promising results.
