- W2000251421 abstract "Immediate weight bearing (WB) has been advocated following ACL reconstruction and is thought to facilitate return of quadriceps activity, and knee extension range of motion (KE ROM), without jeopardizing graft integrity. The purpose of this study was to examine the effect of WB following ACL reconstruction on quadriceps function, KE ROM, knee stability, and anterior knee pain (AKP). Fifty-two patients (27 men and 25 women) undergoing ACL reconstruction were prospectively randomized into two groups: 1) Immediate WB as tolerated 2) Non weight bearing (NWB) for two weeks. Preoperatively, six months and one year post-op, patients were assessed for quadriceps function (VMO EMG), KE ROM (goniometrically), and AKP (subjective score). Results: Forty-four patients returned at 6 months and 37 at 1 year for followup. Normal VMO function was restored at 6 months (WB=93±10%, v NWB=97±9% N.S.) and one year follow up (WB=90±9%, v NWB=100±5%,N.S.). There was no effect of weight bearing on knee stability at 6 months or one year follow-up. Thirty-three precent of eighteen NWB patients and 7% of twenty-six WB patients had reported AKP at six months follow up (P=.03), and 11% of 18 NWB and 5% of 19 WB had AKP at 1 year (N.S.). VMO EMG activity was not different at 6 months or one year follow up. Only one of nine patients with a knee flexion contracture of >5° had AKP at 6 months. These results indicate that WB does not compromise knee stability nor play a role in KE ROM at 6 months. Early weight bearing resulted in a lower incidence of anterior knee pain at 6 months but not at 1 year." @default.
