Allograft vs. autograft for chronic acromioclavicular joint instability: a systematic review and meta-analysis of outcomes and complications.

ABSTRACT:

Background

Chronic acromioclavicular joint (ACJ) instability is commonly treated with surgical reconstruction of the coracoclavicular ligament using tendon grafts. Both autografts and allografts are widely utilized, with no clear consensus on the superior option. Autografts, such as hamstring tendons, provide favorable outcomes but are associated with donor-site morbidity, whereas allografts offer an alternative without harvesting morbidity but may introduce complications such as osteolysis and immune-mediated tissue rejection. The choice between these grafts remains a topic of debate. This systematic review and meta-analysis aim to compare the clinical and radiological outcomes, complication rates, and donor-site morbidity of autograft vs. allograft tendon augmentation in chronic
