About this trial
Residual limping after total hip arthroplasty is a serious complication that lacks effective treatment. The purpose of this study is to evaluate a surgical treatment for residual limping and compare its results with non-surgical treatment. Our hypothesis is that surgical treatment followed by physiotherapy increases hip function and reduces limping compared with non-surgical treatment with physiotherapy alone.
