Early Weightbearing vs. Nonweightbearing in Operative Ankle Fractures .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Early Weightbearing Versus Nonweightbearing After Operative Treatment of an Ankle Fracture: A Multicenter, Noninferiority, Randomized Controlled Trial.
Am J Sports Med. 2021 Aug;49(10): 2689-2696.One hundred and ninety four patients with operative ankle fractures were randomized to undergo early weightbearing (EWB) at 2 weeks postoperatively (n=95) or nonweightbearing (NWB) (n=99) until 6 weeks postoperatively. This was a noninferiority trial design. The primary outcome of interest was the mean difference in the Olerud-Molander ankle score (OMAS) between the two groups at 12 month follow-up. Additional outcomes of interest included time to full weightbearing, time to return to preinjury activities and patient satisfaction. The EWB group demonstrated a noninferior mean difference in the OMAS score when compared to the NWB group. There was no difference in the proportion of patients who were satisfied at 12 month follow-up. The EWB demonstrated shorter time to full weightbearing and return to preinjury activities than the NWB group (p<0.001). No differences in adverse events were noted.
