Surgical repair of the posterolateral meniscal root (PLMR) aims to restore normal biomechanics; however, postoperative rehabilitation strategies remain heterogeneous. The objective of this systematic review was to describe and analyze postoperative weight-bearing (WB) and range-of-motion (ROM) protocols following concomitant PLMR repair and anterior cruciate ligament reconstruction (ACLR), integrating both clinical and biomechanical perspectives. Methods: This systematic review followed PRISMA guidelines and analyzed biomechanical and clinical studies assessing postoperative WB and ROM management following PLMR repair combined with ACLR. Results: Eleven studies were included, describing heterogeneous postoperative rehabilitation protocols for WB and ROM following posterolateral meniscal root repair with ACLR. Biomechanical data consistently showed that root section increased tibial internal rotation and contact pressure on the lateral tibial plateau, whereas repair restored near-native load sharing. Clinically, most authors recommended non-weight-bearing or toe-touch loading for 4\u20136 weeks and flexion limited to 0\u201390\u00b0 during early rehabilitation. Gradual progression to full loading and motion between 8 and 12 weeks was the most consistent strategy. Conclusions: Although the current evidence is limited and mainly based on low-level studies, available data suggest that a cautious and progressive rehabilitation protocol after PLMR repair with ACLR early controlled motion and delayed full loading may optimize repair healing while protecting graft integrity.<\/jats:p>","DOI":"10.3390\/jcm15020542","type":"journal-article","created":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T10:35:52Z","timestamp":1767954952000},"page":"542","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Postoperative Weight-Bearing, Range-of-Motion Protocols and Knee Biomechanics After Concomitant Posterolateral Meniscal Root Repair with ACL Reconstruction: A Systematic Review"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3412-2463","authenticated-orcid":false,"given":"Thibaut","family":"Noailles","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Polyclinique de Bordeaux Nord, 33 rue du Docteur Finlay, 33000 Bordeaux, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7605-3522","authenticated-orcid":false,"given":"Julien","family":"Behr","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, University Hospital of Nantes, 1 Place Alexandre Ricordeau, 44000 Nantes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8300-5653","authenticated-orcid":false,"given":"Nicolas","family":"Bouguennec","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Clinique du Sport, 4 rue Georges-N\u00e8grevergne, 33700 M\u00e9rignac, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lo\u00efc","family":"Geffroy","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Polyclinique de l\u2019Atlantique, Avenue Claude-Bernard, 44819 Saint-Herblain Cedex, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4843-3302","authenticated-orcid":false,"given":"C\u00e9sar","family":"Tourtoulou","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Clinique Aguil\u00e9ra, 21 rue de l\u2019Estagnas, 64200 Biarritz, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alain","family":"Meyer","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Clinique du Sport, 36 Boulevard Saint Marcel, 75005 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1025","DOI":"10.1016\/j.arthro.2009.03.015","article-title":"Meniscal root tears: Diagnosis and treatment","volume":"25","author":"Koenig","year":"2009","journal-title":"Arthroscopy"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"e4","DOI":"10.2106\/JBJS.RVW.15.00082","article-title":"Evaluation, treatment, and outcomes of meniscal root tears: A critical analysis review","volume":"4","author":"Strauss","year":"2016","journal-title":"JBJS Rev."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"452","DOI":"10.1080\/17453674.2016.1202945","article-title":"Posterior meniscal root injuries","volume":"87","author":"Moatshe","year":"2016","journal-title":"Acta Orthop."},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"905","DOI":"10.1177\/0363546514563910","article-title":"Effect of lateral meniscal root tear on the stability of the ACL-deficient knee","volume":"43","author":"Shybut","year":"2015","journal-title":"Am.
