Most patients can be treated with conservative management, while approximately 10% require surgery. The purpose of this systematic review and meta\u2010regression was to evaluate surgical outcomes and determine whether surgical and patient\u2010related factors influence post\u2010operative return\u2010to\u2010sport (RTS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The review was conducted according to PRISMA guidelines. PubMed, Embase and Cochrane Library were searched for studies published between January 2008 and December 2025. Risk of bias assessment was undertaken using the Downs and Black checklist. Data on surgical technique, specific surgical procedures, patient demographics, rehabilitation and outcomes, including Victorian Institute of Sport Assessment\u2013Patellar tendinopathy (VISA\u2010P) and Lysholm knee scores, were extracted. Random\u2010effects meta\u2010analyses and meta\u2010regression were conducted to identify factors influencing time to RTS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 2074 records were screened, and 13 studies met the inclusion criteria. Surgical intervention significantly improved VISA\u2010P scores (weighted mean difference [WMD] of 40.3 [95% confidence interval [CI]: 36.8\u201343.8]) and Lysholm scores (WMD of 41.3 [95% CI: 38.7\u201344.0]). A meta\u2010analysis comparing surgical techniques found significantly longer RTS times following arthroscopic procedures compared to open surgery (WMD, 5.4 weeks;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.049).
