Comparative Study of Hamstrings Autograft vs Double Loop Suture Repair for Reconstruction of Acromioclavicular Joint Dislocation

Background: The aim of the current study is to comparative and evaluate the technique of reconstruction of Acromioclavicular (AC) joint dislocation using tendon autograft (semitendinosus)vs loop suture repair technique and to assess clinical, radiographic results and complications associated with this procedures.

Methods: This is a prospective study was conducted on 30 patients with 30 dislocations from May 2019 till January 2021 including patients with Acromioclavicular joint dislocation (AC joint) presenting to Dr DY PATIL Medical College and Hospital half of which were treated using reconstruction with Semitendinosus autograft and other half with double loop suture repair. The patients were followed-up with mean age being 32.4+-9.3 years and mean follow-up duration was 6.8 month, 6 patients lost in follow-up.

Results: 30 patients with 30 AC joint dislocations were included in this study,24 patients were followed-up and 6 patients were lost in follow-up. We followed the patients for postoperative pain, activity level, arm positioning, and strength of abduction in pounds, range of motion. Constant score was poor for the 16 patients preoperative and excellent for 11, good for 3, fair for 1 and poor for 1 patient postoperative.

By X-ray 14 patients had complete reduction, 2 patients had subluxation <25% immediate postoperative while 10 patients had complete reduction at last follow-up and 6 patients had >25% subluxation.

Conclusion: The results of coracoclavicular re construction using semitendinosus graft have been very promising, safe and feasible surgical technique to treat acute and chronic acromioclavicular joint dislocation than the double loop suture repair. However, the patient should be compliant to the rehabilitation protocol to ensure an optimal outcome of the reconstructive procedure.
