Brief Summary

The functional outcome and quality of life after treatment for an infected hip arthroplasty have been found to be significantly worse compared to an uncomplicated arthroplasty. However, the type of revision surgery chosen to treat the infection plays a role for the functional outcome. The concept of DAIR (debridement, antibiotics and implant retention) has been shown to yield god results with respect to infection control in cases of early infection with a stable implant and better functional results than a to-stage revision. In patients where infection control was achieved after just one DAIR procedure the functional outcome was comparable to an uncomplicated primary arthroplasty. However, it is not known if the operative approach used for the primary and revision surgery plays a role for the functional result after treatment of an infected total hip arthroplasty with DAIR. The project's aim is to investigate if the choice of the operative approach (transgluteal or posterior) for the primary hip replacement and the revision surgery has an influence on the functional result after debridement and implant retention for an infected total hip replacement.

Study Arms (2)

Transgluteal approach to the hip joint

Patients who have been revised once for an infected total hip replacement with debridement and implant retention and in whom both the primary hip arthroplasty and the revision procedure were performed through a transgluteal approach.

Procedure: Transgluteal approach to the hip joint

Posterior approach to the hip joint

Patients who have been revised once for an infected total hip replacement with debridement and implant retention and in whom both the primary hip arthroplasty and the revision procedure were performed through a posterior approach.

Procedure: Posterior approach to the hip joint

Interventions

Operative approach to the hip joint where the abductors are partly detached from the greater trochanter and the hip joint is approached through the anterior part of the capsule.

Also known as: Direct lateral approach to the hip joint
Transgluteal approach to the hip joint

Operative approach to the hip joint where the short external rotators are detached from the greater trochanter and the hip joint is approached through the posterior part of the capsule.

Also known as: Posterolateral approach to the hip joint
Posterior approach to the hip joint

Study Population

The potential study participant will be identified in the Norwegian Arthroplasty Register.

You may qualify if:

  • The infected total hip arthroplasty has only been revised once.
  • The revision procedure was a debridement and implant retention.
  • Both, the primary and the revision procedure were performed through the same surgical approach; either the transgluteal or the posterior approach.

You may not qualify if:

  • No written informed consent.
