Descriptive statistics are presented. The Methodological Index for Non\u2010Randomized Studies (MINORS) scale was used to assess quality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Twenty\u2010five studies were included, examining 1,085 patients (n\u00a0= 140 BC; n\u00a0= 945 LD), of mean age 25.0\u00a0years, 27.1% female, and mean 3.1\u00a0years of follow\u2010up. MINORS scores for BC and LD were 11.2 and 9.8, respectively. Regardless of positioning, patients did not differ across numerous outcomes and various surgical factors (e.g., number of portals, anchors, anchor types, concomitant pathology, or postoperative rehabilitation protocol). Postoperative patient satisfaction ranged from 85% to 87.5% and 93% to 100% for patients treated in BC and LD positions, respectively. Although not reported for BC, overall and preinjury return\u2010to\u2010play (RTP) rates in LD patients ranged from 72% to 100% and 55% to 100%, respectively, returning from 3 to 7.6\u00a0months postoperatively. Failure rates in the BC and LD positions ranged from 0% to 9.4% and 0% to 29%, respectively. There were no differences in reported incidences of neuropraxia, stroke, nonfatal pulmonary embolus, vision loss, cardiac arrest, or other positioning\u2010related complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Arthroscopic management of posterior\u2010inferior shoulder instability has a successful track record and minimal complication profile. Although patient positioning appears to influence results, with those treated in\u00a0the LD position experiencing marginally higher patient satisfaction and failure rates, the current data prevent any conclusions being made regarding the superiority of one approach over another. As the clinical relevance of patient positioning remains to be determined, larger, higher\u2010level study designs with long\u2010term follow\u2010up are required.<\/jats:p>\n
