Brief Summary

Total hip arthroplasty is a method of choice for treating advanced osteoarthritis of the hip and one of the most frequent orthopedic procedures. Of all hip surgical approaches described, the tendency for minimally invasive techniques has been dominated over the last few years due to faster patient mobilization, reduced postoperative pain and need for blood transfusion. Two of the most common approaches used for minimally invasive total hip arthroplasty are: AMIS anterior approach and mini-posterior approach, which is a modification of the standard posterior approach. The purpose of this study is the biochemical, imaging and clinical evaluation of the tissue damage caused by the above-mentioned techniques of minimally invasive total hip arthroplasty.

Outcome Measures

Primary Outcomes (1)

  • Tissue damage change

    Investigate and quantify at the biochemical level with all available biomarkers the extent of tissue damage caused during a hip arthroplasty between different hip surgical approaches.

    Change from 6 to 24 and then 48 hours post-surgery

Secondary Outcomes (2)

  • Imaging

    Day 30 after surgery

  • Clinical Tests change

    Change to clinical test from Day 2 to day 15 and then day 30 post-surgery

Study Arms (3)

total hip arthroplasty via the mini posterior approach

ACTIVE COMPARATOR

total hip arthroplasty via the mini posterior approach. This approach was first described by Kocher and Langenbeck and later modified by Gibson in 1950. There is a convex incision centered on the posterior rim of the major trochanter. The incision follows the curve of the buttock and at the height of the posterior lip of the major trochanter, it is peripherally oriented along the posterior outer surface of the femur. The major gluteus is divided along the muscle fibers. Guiding sutures are inserted into the tendon mass of the hip rotor muscles just prior to their origin on the major trochanter and dissected to expose and subsequently retract the posterior hip capsule.

Procedure: Mini posterior approach Total Hip Replacement

THR via the anterior approach without traction table

ACTIVE COMPARATOR

The anterior approach is a modification of the classic Smith- Peterson anterior hip approach as described by Berend et al in 2009 \[7\]. This approach utilizes the intermuscular plane between the tendon fascia lata and the sartorius muscle, and laterally repairs the fibers of the rectus femur to expose and enclose the anterior pubic joint. A surgical traction table may be used during surgery.
