Percutaneous Assisted Approach for Total Hip Replacement and it's Effect on Functional Rehabilitation.

Universiteit Antwerpen

Status: Unknown

Conditions: Total Hip Arthroplasty

Treatments: Procedure: Ceramic on ceramic couple; Other: Usual care; Procedure: Anterolateral approach; Procedure: Percutaneous assisted approach

Study type: Interventional

Funder types: Other

Details and patient eligibility

About

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.

Enrollment: 30 estimated patients

Sex: All

Ages: 50 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• unilateral hip arthritis or avascular necrosis (AVN) in need for total hip replacement

Exclusion criteria

• Comorbidities affecting functional outcome
• Symptomatic lumbar pathology
• Need of surgery or intervention on the ipsilateral knee and/or ankle/foot
• Neurological disorders such as Parkinsonism and previous cardiovascular accidents (CVA)

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

30 participants in 2 patient groups

Percutaneous assisted approach

Experimental group

Description:

In this technique, a second small incision (1 cm) at the anterior border of the femur is made. A canulla is placed underneath the muscle and used to pass the reamers in the direction of the acetabulum. There's no need to enlarge the skin incision or to release more muscle insertion to achieve good working access to the acetabulum. Two advantages can be defined: sparing of the gluteus medius muscle and safe access to the acetabulum to obtain perfect positioning of the implants.

Treatment:

Other: Usual care

Procedure: Ceramic on ceramic couple

Procedure: Percutaneous assisted approach

Anterolateral approach

Active Comparator group

Description:

A standard transgluteal approach is used. This means a large part of the gluteus medius muscle is released to obtain good access to the acetabulum.

Treatment:

Other: Usual care

Procedure: Ceramic on ceramic couple

Procedure: Anterolateral approach
