Brief Summary in Lay Language

This study is investigating potential side-to-side differences between the operated side and the non-operated side of total hip arthoplasty patientsat least 1year after operation. The hip strength, the range of motion, the balance as well as the spatio-temporal gait parameters are analyzed between the operated and the non-operated side. Participants are included in the study if their age ranges between 50 and 70 and if they received the total hip replacement at least 1 year ago or longer. Based on some studies that show persisting deficits in strength and balance on the operated side 1 year after the operation, we hypothesize that we will detect side-to-side differences even further years after total hip arthroplasty.

Primary Outcome

The primary outcome parameters are maximum isometric hip strength, hip range of motion, spatio-temporal gait parameters and length of center of pressure as a measure of balance. These parameters are compared between the operated and the non-operated side.

Maximum isometric strength is tested in hip extension, flexion, abduction and adduction. Range of motion of the hip joint is measured in an active movement in hip extension, hip flexion and hip abduction. For the gait analysis spatio-temporal gait parameters as step length, step time, single-leg stance etc are analyzed. Balance is measured in the single-leg stance on a force plate.

Secondary Outcome

Another criterium is the comparison of the parameters of the total hip replacement patients with a healthy, age-matched control group
