Discussion
This study describes a protocol for a RCT that will investigate
whether the addition of hip abductor muscle
strengthening to the usual care rehabilitation program
following TKA leads to superior performance based and
patient reported outcomes. This is the first reported
study to specifically assess the effect of hip strengthening
exercises in this population. The trial will provide information
to clinicians to potentially improve outcomes for
patients with TKA. This is particularly relevant as the
number of patients undergoing TKA is rapidly increasing
worldwide [79–81
