An increasing incidence of knee OA and greater utilization of TKA stresses the need for a better understanding of how postoperative care can influence the disability associated with knee OA.
The overall goal of this investigation is to describe the time course of recovery of impairments and function, as well as to provide direction to rehabilitation efforts designed to improve function for individuals with TKA.
We hypothesized that quadriceps strength would be more strongly correlated with functional performance than knee flexion ROM or pain at all time periods studied before and after TKA, and patients with stronger quadriceps muscles would have
superior functional outcomes to those with weaker quadriceps.
