Immediate weight bearing without immobilization for operatively treated ankle fractures is safe – A systematic review.

This systematic literature review compared weight bearing (WB) vs. partial- / non-weight bearing (NWB) and mobilization (MB) vs. immobilization (IMB) for surgically treated ankle fractures. Five databases were searched. Eligible were (quasi-)randomized controlled trials comparing at least two different postoperative treatment protocols. The risk of bias was assessed using the RoB-2 toolkit. The primary outcome was complication rate, secondary outcome Olerud and Molander Ankle Score (OMAS), range of motion (ROM), and return to work (RTW). Out of 10,345 studies, 24 papers were eligible. Thirteen studies (n = 853) compared WB/NWB, 13 studies (n = 706) MB/IMB with a moderate study quality. WB did not increase the risk for complications but resulted in superior short-term outcomes for OMAS, ROM, RTW. 12 studies found no inferior results for MB compared to IMB. Early and immediate WB and MB do not increase the complication rates but result in superior short term outcome scores. Level I Systematic Review [ABSTRACT FROM AUTHOR]
