The role of early weight bearing in the aftertreatment of unilateral displaced intraarticular calcaneal fractures: a systematic review and pooled analysis

Abstract Background Displaced intraarticular calcaneal fractures (DIACFs) remain a complex challenge in orthopedic practice due to their complexity and the intricate nature of surgical interventions. While surgical techniques have evolved, postoperative rehabilitation is equally crucial for achieving optimal outcomes. This systematic review evaluates the effects of early weight bearing (EWB) in surgically treated patients with unilateral DIACFs on patient-reported outcomes, health-related quality of life, postoperative pain, differences in Böhler’s angle, and complication rates. Methods A systematic literature search was performed across PubMed, Embase, and Cochrane Library up to January 2025. Eligible studied included adults (≥ 18 years) who underwent surgery for unilateral DIACFs (Sanders type II–IV), implemented an EWB protocol, reported at least one patient-reported outcome, and were published from 2000 onward. Data extraction and quality assessment were conducted using the Newcastle–Ottawa Scale. Results From 1007 identified records, 20 studies (n = 1051 DIACFs) met the inclusion criteria. Pooled results showed a mean American Orthopedic Foot and Ankle Society (AOFAS) Score of 85.7, Maryland Foot Score of 91.1, and visual analog score of 1.9. The analysis revealed a decline of 0.4 degrees in Böhler’s angle from postoperative to last follow-up. The overall complication rate was 13.9%. Conclusions EWB protocols appear to be safe and beneficial in the postoperative management of DIACFs, yielding favorable outcomes without increased complication rates. These findings support the reconsideration of current conservative weight-bearing guidelines. Future research should focus on the development of standardized, evidence-based after-treatment guidelines. Level of evidence Level I. Trial registration PROSPERO CRD42022280985
