The purpose of this investigation was to systematically review and compare outcomes of patients undergoing glenoid augmentation using free bone block autografts versus allografts.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A systematic review using PubMed, MEDLINE, Embase, and the Cochrane Library databases was performed in line with the PRISMA statement. Studies reporting outcomes of patients treated with free bone block procedures for anterior shoulder instability with minimum 2\u2010year follow\u2010up were included. Random effects modelling was used to compare patient\u2010reported outcomes, return to sports, recurrent instability, non\u2010instability related complications, and development of arthritis between free bone block autografts and allografts.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Eighteen studies comprising of 623 patients met the inclusion criteria for this investigation. There were six studies reporting on the use of allografts (of these, two used distal tibial, three iliac crest, and one femoral head allograft) in 173 patients and twelve studies utilizing autografts (of these, ten used iliac crest and two used free coracoid autograft) in 450 patients. Mean age was 28.7\u2009\u00b1\u20094.1 years for the allograft group and 27.8\u2009\u00b1\u20093.8 years for the autograft group (n.s). Mean follow\u2010up was 98\u00a0months in autograft studies and 50.8\u00a0months for allograft studies (range 24\u2013444\u00a0months, n.s). Overall mean increase in Rowe score was 56.2 with comparable increases between autografts and allografts (n.s). Pooled recurrent instability rates were 3% (95% CI, 1\u20137%; <jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u200977%) and did not differ between the groups (n.s). Arthritic progression was evident in 11% of autografts (95% CI, 2\u201327%; <jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u200990%) and 1% (95% CI, 0\u20138%; <jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u200963%) of allografts (n.s). The overall incidence of non\u2010instability related complications was 5% (95% CI, 2\u201310%; <jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u2009=\u200981%) and was similar between the groups (n.s).

Outcomes and complication incidence using autografts and allografts were comparable. Due to the high degree of heterogeneity in the data and outcomes reported in available studies, which consist primarily of retrospective case series, future prospective trials investigating long\u2010term outcomes using free bone block autograft versus allograft for anterior shoulder instability with glenoid bone loss are warranted.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
