Abstract
Background:
The optimal timing of weightbearing following surgical fixation of ankle fractures remains a topic of clinical debate. Although early weightbearing (EWB) may promote faster functional recovery, concerns about complication risks have limited its widespread adoption. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of EWB compared with LWB in adults undergoing ankle fracture fixation, using evidence from high-quality randomized controlled trials (RCTs) published since 2000.
Methods:
A comprehensive literature search was conducted across 6 electronic databases (MEDLINE, Embase, CENTRAL, Scopus, CINAHL, and Web of Science) from January 2000 to May 2025. Only RCTs comparing EWB (initiated within 3 weeks postoperatively) to LWB (≥4 weeks) following surgical fixation of ankle fractures were included. Primary outcomes were functional recovery, primarily assessed by the Olerud-Molander Ankle Score (OMAS), and EuroQol 5-dimension visual analogue scale (EQ 5D VAS). Secondary outcomes included time to return to work and complication rates. Meta-analyses were conducted using fixed or random effects models based on heterogeneity.
Results:
Five RCTs involving 1030 patients were included. OMAS at 6 weeks (5 studies) and 3 months (4 studies) favored EWB (6 weeks: MD 6.51, P < .00001; 3 months: MD 3.24, P = .005) and time to return to work (3 studies) was shorter with EWB. Complication rates were similar. Because several trials excluded patients with BMI >30, trimalleolar or syndesmotic injuries, and many enrolled patients were <65 years, these findings apply primarily to lower-risk patients treated with contemporary fixation.
Conclusion:
EWB after ankle fracture fixation leads to improved early functional outcomes and quicker return to work, with no clear increase in complications, in primarily lower-risk patients.
