Overview

Brief Summary

The purpose of this study is to investigate whether revalidation following total hip replacement through the percutaneous approach is faster or better than following the anterolateral approach. We assume this would be the case since it is possible to spare a large part of the gluteus medius muscle with the percutaneous approach.

Outcomes

Primary Outcomes

change in time needed for the timed get up and go test

Time Frame: baseline, 4 weeks, 12 weeks

The subject is asked to stand up from a chair, walk 3m to a cone, return to the chair and sit down again. The time needed to perform this test is recorded in seconds.

Secondary Outcomes

surface electromyography (sEMG) of gluteus medius(12 weeks)
Change in hip abductor muscle strength measured by MicroFET 2(baseline, 4 weeks, 12 weeks)
Change in time needed to complete the 5 times sit-to-stand test(baseline, 4 weeks, 12 weeks)
Change in distance walked during the 6 minute walking test(baseline, 4 weeks, 12 weeks)
Score on the trendelenburg test(4 weeks)
Change in knee extensor muscle strength measured by MicroFET 2(baseline, 4 weeks, 12 weeks)
Score on the Trendelenburg test(12 weeks)
Change in score on the Oxford Hip Score(baseline, 4 weeks, 12 weeks)
Change in score on the SF-36 and it's subscales(baseline, 4 weeks, 6 weeks)
