About the trial
What the trial wants to find out
Residual limping after total hip arthroplasty is empirically associated with the use of lateral approach but has been reported in litterature even with the use of posterior approach. The purpose of this clinical trial is to compare the risk of residual limping one year after total hip arthropasty between lateral and posterior approach.
The 2 groups in the trial
- Lateral approachExisting treatment, for comparison
290 participants receive their hip prosthesis through a lateral approach. The anterior third of m. gluteus medius along with the corresponding part of m. vastus lateralis are detached from the greater trochanter and the anterior capsule is excised for the exposure of the hip joint. After implant insertion, the gluteus medius is reinserted into the greater trochanter with non-absorbable sutures. Participants are followed at three and 12 months by a physiotherapist.
- Posterior approachExisting treatment, for comparison
290 participants receive their hip prosthesis through a posterior approach. The m. piriformis gemelli and obturator internus are detached from the greater trochanter and the posterior capsule is incised for the exposure of the hip joint. After implant insertion, the posterior capsule as well as m piriformis and the external rotators are reinserted into the greater trochanter with non-absorbable sutures. Participants are followed at three and 12 months by a physiotherapist.
