Abstrakt:	Background: Postoperative care protocols for ankle fracture surgery remain controversial with variability among care providers. This prospective controlled trial compared 12-week postoperative outcomes for immediate unprotected weightbearing (IMWB) vs nonweightbearing (NWB) for 2 weeks in a splint followed by weightbearing as tolerated (WBAT) in a boot after surgical fixation of selected low-energy ankle fractures without superior articular involvement. Methods: Eighty-seven patients undergoing surgical fixation of ankle fractures at a single level 1 trauma center were recruited according to specific criteria and enrolled by presentation date. The first 43 eligible patients were allocated to the control group, with NWB in a splint for 2 weeks followed by WBAT in a walker boot. The next 44 patients recruited were allocated to the IMWB group. The primary outcome was the Olerud-Molander score (OMAS). Secondary outcome measures included the Euroquol-5D (EQ5D) score and Work Productivity and Activity Impairment: Specific Health Problem (WPAI:SHP) scores, ankle range of motion (ROM), wound complications, time to return to work, radiograph measurements, and fracture reduction loss. In this perioperative-focused study, we collected data on patients until 12 weeks postoperation. Results: The IMWB group had 5 superficial wound complications vs 1 in the control group. At 12 weeks, we found no difference in OMAS, EQ5D, WPAI:SHP scores, ROM, time to return to work, or radiographic measurements. Conclusion: In this short-term and relatively small prospective trial, we found more wound complications among patients treated with immediate unprotected weightbearing compared with patients treated with 2 weeks of NWB followed by protected weightbearing. Given the low incidence and small sample size, we do not know if these observed findings are generalizable. However, we also found no difference in functional outcomes at 12 weeks postoperation between these 2 groups. In light of that, we do not recommend IMWB after open reduction internal fixation of low-energy ankle fractures with plate and/or screw fixation. Level of Evidence: Level II, prospective controlled trial.
