However, with the increasing incidence of sports-related injuries and growing demand for rehabilitation services, conventional rehabilitation models\u2014largely reliant on therapists\u2019 experience and subjective assessment\u2014are increasingly insufficient to meet the clinical need for precise and individualised rehabilitation programmes. This study aimed to evaluate the effectiveness of a rehabilitation protocol incorporating an artificial intelligence (AI)-based assessment and correction system on functional recovery following ACL reconstruction. Methods: Using convenience sampling, 80 patients undergoing ACL reconstruction between June to December 2024 were recruited for this randomised controlled trial. Participants were randomly assigned to either a control group (n = 40), which received conventional functional exercise training, or a trial group (n = 40), which received rehabilitation intervention guided by an AI-based assessment and correction system. Knee function scores (Lysholm score, IKDC score), Berg Balance Scale (BBS) scores, joint range of motion (ROM), and rehabilitation exercise compliance scores were collected and analysed 1, 2, 3, and 4 months postoperatively. Results: Compared with the control group, the trial group demonstrated significantly greater improvements in Lysholm score, IKDC score, BBS score, and active knee joint ROM (p &lt; 0.05) at postoperative assessment points. Additionally, rehabilitation exercise adherence was significantly higher in the trial group compared to the control group (p &lt; 0.05). Conclusions: Rehabilitation protocols integrating AI-based assessment and correction systems effectively enhance knee function recovery, joint mobility and balance ability following ACL reconstruction. Moreover, these protocols significantly improve rehabilitation exercise adherence, demonstrating superior efficacy compared to conventional rehabilitation approaches. This digital rehabilitation model represents an efficient and promising intervention for postoperative ACL rehabilitation.<\/jats:p>","DOI":"10.3390\/jcm15020575","type":"journal-article","created":{"date-parts":[[2026,1,12]],"date-time":"2026-01-12T08:20:37Z","timestamp":1768206037000},"page":"575","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Evaluation of the Efficacy of an Artificial Intelligence-Based Assessment and Correction System in the Rehabilitation of Patients Following Anterior Cruciate Ligament Reconstruction Surgery"],"prefix":"10.3390","volume":"15","author":[{"given":"Tingting","family":"Zhu","sequence":"first","affiliation":[{"name":"Department of Orthopedics, Jinling Clinical Medical College, Nanjing Medical University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingjing","family":"Pu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-8220-1567","authenticated-orcid":false,"given":"Chaolong","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Ruan","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ping","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojiang","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nirong","family":"Bao","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yueying","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-8510-1242","authenticated-orcid":false,"given":"Aiqin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Medical Information Data Room, Jinling Clinical Medical College, Nanjing Medical University, Nanjing 210002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"131","DOI":"10.1007\/s00167-021-06476-0","article-title":"Anterior cruciate ligament reconstruction with lateral extraarticular tenodesis better restores native knee kinematics in combined ACL and meniscal injury","volume":"30","author":"Gibbs","year":"2022","journal-title":"Knee Surg.
