Brief summary
Despite the widespread use of total hip and knee arthroplasty, there is a notable lack of consensus regarding postoperative treatment, mostly because of the lack of well-designed studies testing the efficacy and effectiveness of such practices. In particular, there are no evidence-based recommendations on the amount of weight that the patient should be advised to bear on the operated leg after the operation.
Interventions
BEHAVIORALRecommend full weight-bearing
The full weight-bearing group is trained in 4-point gait with crutches and is recommended to put as much weight as tolerated on the leg on which surgery has been performed, immediately after surgery
BEHAVIORALRecommend parital weight-bearing
The partial weight-bearing group is trained in 3-point gait with crutches and is instructed to limit weight-bearing of the affected leg to 20kg for a period of six-weeks. Scales are used to train these participants not to exceed 20kg
