Contralateral Limb Function Before THA: An Indicator of Postop Gait Speed 

In a prospective case-control study reported in JBJS, Ohmori et al. evaluated factors related to postoperative gait speed in patients with osteoarthritis undergoing total hip arthroplasty. They found that the preoperative, contralateral-side OLST (one-leg standing time) was a significant factor (p < 0.001) for postoperative comfortable gait speed. They also found that preoperative, contralateral-side knee extensor strength was a significant factor (p = 0.018) for postoperative maximum gait speed. 

Reflecting on their findings, the authors note: 

THA is a procedure that typically has a good a postoperative prognosis. However, some patients do not have sufficient satisfaction. Investigating reasons for this, we found that the functional status of the nonoperative lower limb is an important factor. 

Surgical intervention before lower-limb function on the contralateral side declines, or a preoperative rehabilitation intervention on the contralateral side, may improve the THA outcome.”
