摘      要：Purpose:The purpose of this study was to compare knee biomechanics of the replaced limb to the non-replaced limb of total knee replacement(TKR)patients and healthy controls during walking on level ground and on decline surfaces of 5°,10°,and 15°.Methods:Twenty-five TKR patients and 10 healthy controls performed 5 walking trials on different decline slopes on a force platform and an instrumented ramp *** analyses of variance,2×2(limb×group)and 2×4(limb×decline slope),were used to examine selected biomechanics ***:The replaced limb of TKR patients had lower peak loading-response and push-off knee extension moment than the non-replaced and the matched limb of healthy *** differences were found in loading-response and push-off knee internal abduction moments among replaced,non-replaced,and matched limb of healthy *** knee flexion range of motion,peak loading-response vertical ground reaction force,and peak knee extension moment increased across all slope comparisons between 0°and 15°in both the replaced and non-replaced limb of TKR ***:Downhill walking may not be appropriate to include in early stage rehabilitation exercise protocols for TKR patients.
