Surgical management, including isolated open reduction and internal fixation (ORIF) and ORIF combined with acute total hip arthroplasty (THA) (combined hip procedure\u2014CHP), have advanced considerably. Nevertheless, optimal postoperative rehabilitation and particularly weight-bearing (WB) recommendations remain controversial and inconsistent. This review aims to assess rehabilitation protocols, focusing on WB strategies following the surgical treatment of acetabular fractures in older adults. It also examines differences in WB restrictions by surgical technique (ORIF vs. CHP) and their impact on recovery, complications, reoperations, and mortality. Methods: A systematic review of PubMed, Embase, and the Cochrane Library (2006\u20132024) included studies involving patients aged \u226565 years treated surgically for displaced acetabular fractures. Data included WB protocols (full, partial, toe-touch), length of stay (LOS), healing, functional outcomes (mobility, Harris and Oxford Hip Scores), complications, reoperations, delayed THA, compliance, readmission, and mortality. Due to heterogeneity, findings were narratively synthesized. Risk of bias was assessed using ROBINS-I and RoB2. Results: Twenty studies involving 929 patients (530 isolated ORIF, 399 CHP) were analyzed. The overall mean follow-up was 3.5 years (range: 1\u20135.25 years). Postoperative WB protocols were reported in 19 studies (95%). Immediate full WB was permitted in 0% of isolated ORIF studies (0\/13), with partial WB recommended by 62% (8\/13) for durations typically between 6 and 12 weeks. On the other hand, immediate full WB was allowed in 53% (9\/17) of CHP studies. Functional outcomes were moderate following isolated ORIF (mean HHS: 63\u201382 points), with delayed THA conversion rates ranging from 16.5% to 45%. CHP demonstrated superior functional outcomes (mean HHS: 70\u201392 points), earlier independent ambulation, and higher patient satisfaction (74\u201390%), yet increased orthopedic complications, including dislocations (8\u201311%) and implant loosening (up to 18%). LOS varied from 12 to 21 days (mean 16 days) for isolated ORIF and from 8 to 25 days (mean 17 days) for CHP. Readmission within 30 days was not explicitly reported in any study. Mortality at 1 year varied significantly (ORIF: 0\u201325%; CHP: 0\u201314%), increasing markedly at long-term follow-up (up to 42% ORIF, up to 70% CHP at five years). Compliance with WB restrictions was monitored in only two studies (11%). Conclusions: Postoperative rehabilitation after acetabular fracture surgery in older adults remains inconsistent and lacks standardization. Combining ORIF with acute THA may enable earlier weight-bearing and improved short-term function but carries risks such as dislocation and implant loosening. In contrast, isolated ORIF avoids these implant-related complications but often requires prolonged weight-bearing restrictions. Robust evidence is still missing. Future trials are essential to establish standardized protocols that balance mechanical protection and functional recovery.<\/jats:p>","DOI":"10.3390\/jcm14144912","type":"journal-article","created":{"date-parts":[[2025,7,11]],"date-time":"2025-07-11T11:26:37Z","timestamp":1752233197000},"page":"4912","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Rehabilitation Protocols for Surgically Treated Acetabular Fractures in Older Adults: Current Practices and Outcomes"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-3959-0026","authenticated-orcid":false,"given":"Silviya","family":"Ivanova","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery and Traumatology, Inselspital, Bern University Hospital, 3010 Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ondrej","family":"Prochazka","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Traumatology, Inselspital, Bern University Hospital, 3010 Bern, Switzerland"},{"name":"Department of Plastic and Hand Surgery, Inselspital, Bern University Hospital, 3010 Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5205-7696","authenticated-orcid":false,"given":"Peter V.","family":"Giannoudis","sequence":"additional","affiliation":[{"name":"Academic Department of Trauma & Orthopedics, School of Medicine, University of Leeds, Leeds LS2 9JT, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theodoros","family":"Tosounidis","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Medical School, University of Crete, 71110 Heraklion, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2761-565X","authenticated-orcid":false,"given":"Moritz","family":"Tannast","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Traumatology, Inselspital, Bern University Hospital, 3010 Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0708-4097","authenticated-orcid":false,"given":"Johannes D.","family":"Bastian","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery and Traumatology, Inselspital, Bern University Hospital, 3010 Bern, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1061","DOI":"10.1016\/j.jcot.2020.10.029","article-title":"Management of acetabular fractures in elderly patients","volume":"11","author":"Shah","year":"2020","journal-title":"J.
