How knee alignment changes after total hip replacement

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this prospective cohort study, researchers will measure knee alignment before and after total hip arthroplasty using full-length radiographs to see how knee biomechanics change after the hip procedure. Coronal plane alignment parameters will be quantified to characterize any shifts in knee phenotype following surgery. The findings may help understand the biomechanical impact of THA on the knee and inform future care.
