All studies reporting on clinical and radiological outcome as well as complications after ACJ reconstruction using allo\u2010 and\/or autografts were included.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 29 articles, including 2 prospective and 27 retrospective studies, involving 622 patients, reconstructed with either allo\u2010 (<jats:italic>n<\/jats:italic>\u2009=\u2009360) or auto\u2010grafts (<jats:italic>n<\/jats:italic>\u2009=\u2009262), for acromio\u2010clavicular joint instability were identified and included in this review. The majority of studies had low sample sizes (66.7% below <jats:italic>n<\/jats:italic>\u2009=\u200920), were retrospective (93.3%), with short\u2010term follow\u2010ups (average 26.2\u2009\u00b1\u200912.6\u00a0months; range 6\u2013186). The study with the largest sample size (<jats:italic>n<\/jats:italic>\u2009=\u2009128) did not report clinical outcome. A comparison between allo\u2010 and auto\u2010graft showed no significant differences regarding age, gender, and follow\u2010up times. Clinical outcome was comparable in both groups, loss of reduction (LOR) and complication rates were higher in the allograft group. Overall a reduction of LOR was shown if additional horizontal stabilization was performed. Also a higher LOR and revision rate was documented in allografts without suture or suture\u2010tape augmentation. The use of more clavicular drill\u2010holes correlated with a higher frequency of fracture.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A systematic review of the available peer\u2010reviewed literature addressing allograft and autograft reconstruction of unstable coracoclavicular ligaments shows that the published studies are generally of low quality with low levels of evidence. The published literature shows no significant difference in clinical outcomes between the use of autografts or allografts in ACJ reconstruction surgery. Surgical techniques utilizing additional horizontal stabilization may contribute to lower rates of LOR. In cases where allograft tissue is used for ACJ reconstruction the use of suture\/tape augmentation may reduce LOR rates as well as revision rates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
