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

Area of Science:

• Orthopedic surgery
• Sports medicine
• Biomaterials in orthopedics

Background:

• Acromioclavicular joint (ACJ) disruptions are common shoulder injuries.
• Surgical stabilization aims to restore joint integrity and function.
• Prosthetic ligaments offer an alternative for ACJ stabilization.

Purpose of the Study:

• To evaluate the outcomes of ACJ stabilization using a braided polyester prosthetic ligament.
• To assess functional recovery and patient satisfaction after prosthetic ligament use for ACJ injuries.

Main Methods:

• A cohort of 21 male patients with Rockwood type 3, 4, and 5 ACJ disruptions were treated.
• Stabilization was performed using a braided polyester prosthetic ligament.
• Patient outcomes were assessed using the Constant Score, individualized Constant Score, Oxford Shoulder Score, and abduction power.

Main Results:

• The mean Constant Score was 86.8 and the mean Oxford Shoulder Score was 43.1.
• Operated shoulders achieved 82% of the abduction power compared to the normal side.
• Twenty out of 21 patients reported satisfaction with the procedure, with one case of dissatisfaction due to scapulothoracic bursitis.

Conclusions:

• Braided polyester prosthetic ligaments provide a good outcome for stabilizing disrupted acromioclavicular joints.
• The prosthetic ligament is a viable option for ACJ stabilization, demonstrating high patient satisfaction and functional improvement.
