Current literature reports a high rate of return to play, but there are limited data on performance after ACL reconstruction (ACLR).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose\/Hypothesis:<\/jats:title>\n                    <jats:p>To determine return to play and player performance in the first and second seasons after ACLR in NBA players. We hypothesized that players would return at a high rate. However, we also hypothesized that performance in the first season after ACLR would be worse as compared with the preinjury performance, with a return to baseline by postoperative year 2.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design:<\/jats:title>\n                    <jats:p>Case series; Level of evidence, 4.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>An online database of NBA athlete injuries between 2010 and 2019 was queried using the term ACL reconstruction. For the included players, the following data were recorded: name; age at injury; position; height, weight, and body mass index; handedness; NBA experience; dates of injury, surgery, and return; knee affected; and postoperative seasons played. Regular season statistics for 1 preinjury season and 2 postoperative seasons were compiled and included games started and played, minutes played, and player efficiency rating. Kaplan-Meier survivorship plots were computed for athlete return-to-play and retirement endpoints.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 26 athletes underwent ACLR; of these, 84% (95% CI, 63.9%-95.5%) returned to play at a mean 372.5 days (95% CI, 323.5-421.5 days) after surgery. Career length after injury was a mean of 3.36 seasons (95% CI, 2.27-4.45 seasons). Factors that contributed to an increased probability of return to play included younger age at injury (odds ratio, 0.71 [95% CI, 0.47-0.92]; P = .0337) and fewer years of experience in the NBA before injury (odds ratio, 0.70 [95% CI, 0.45-0.93]; P = .0335). Postoperatively, athletes played a significantly lower percentage of total games in the first season (48.4%; P = .0004) and second season (62.1%; P = .0067) as compared with the preinjury season (78.5%). Player efficiency rating in the first season was 19.3% less than that in the preinjury season ( P = .0056). Performance in the second postoperative season was not significantly different versus preinjury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>NBA players have a high rate of RTP after ACLR. However, it may take longer than a single season for elite NBA athletes to return to their full preinjury performance. Younger players and those with less NBA experience returned at higher rates.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/2325967120981649","type":"journal-article","created":{"date-parts":[[2021,2,26]],"date-time":"2021-02-26T10:47:59Z","timestamp":1614336479000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":30,"title":["Performance After Anterior Cruciate Ligament Reconstruction in National Basketball Association Players"],"prefix":"10.1177","volume":"9","author":[{"given":"Steven F.","family":"DeFroda","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Warren Alpert School of Medicine, Brown University, Providence, Rhode Island, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Devan D.","family":"Patel","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Warren Alpert School of Medicine, Brown University, Providence, Rhode Island, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Milner","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Warren Alpert School of Medicine, Brown University, Providence, Rhode Island, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel S.","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Warren Alpert School of Medicine, Brown University, Providence, Rhode Island, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brett D.","family":"Owens","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Warren Alpert School of Medicine, Brown University, Providence, Rhode Island, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,2,26]]},"reference":[{"key":"bibr1-2325967120981649","unstructured":"Basketball-Reference.com.
