Stabilisation for the disrupted acromioclavicular joint using a braided polyester prosthetic ligament

Abstract

Purpose. To report outcomes of 21 men who underwent stabilisation for the disrupted acromioclavicular joint (ACJ) using a braided polyester prosthetic ligament. Methods. 21 men aged 23 to 76 (mean, 43) years underwent stabilisation for the disrupted ACJ of Rockwood type 3 (n=12), type 4 (n=1), and type 5 (n=8) using a braided polyester prosthetic ligament. Results. The mean time from injury to surgery was 6.8 (range, 0–19) months. The mean follow-up duration was 30 (range, 7–67) months. The mean Constant Score was 86.8 (range, 62–100), and the mean individualised Constant Score was 88.5 (range, 68–100). The mean Oxford Shoulder Score was 43.1 (range, 28–48). The mean abduction power of the operated side was 82% (range, 31%–97%) that of the normal side. 20 patients were satisfied with the procedure. One patient was dissatisfied who developed scapulothoracic bursitis. One patient required arthroscopic subacromial decompression for impingement. One patient sustained a redislocation following a fall at 6 weeks and declined further surgery. Conclusion. The braided polyester prosthetic ligament achieved good outcome for patients undergoing stabilisation for the disrupted ACJ.
