Bilateral simultaneous two-incision minimally invasive total hip arthroplasty.
BACKGROUND
This study aimed to assess the feasibility of bilateral simultaneous minimally invasive two-incision total hip arthroplasty in terms of clinical and radiological outcomes, complications, and patient satisfaction.


METHODS
A total of 62 patients, ages 24-69 years, were operated on with bilateral simultaneous minimally invasive total hip arthroplasty using a modified two-incision technique, after which they were followed for an average 41 months. The acetabular component was inserted through part of the Watson-Jones approach, and a femoral component was inserted through a space between the gluteus medius and piriformis tendon.


RESULTS
The mean duration of surgery was 180.4 min, and the mean perioperative blood loss was 1513.2 ml. There were no intraoperative complications. Postoperative periprosthetic fracture occurred in two patients and delayed infection in one patient. The average Harris Hip Score improved from 41.8 to 95.3. The WOMAC score improved from an average of 66.2 to 5.0. The average lateral opening angle of the acetabulum was 40 degrees , and the angle of anteversion was 12 degrees . All the femoral components were implanted in neutral to 5 degrees valgus position.


CONCLUSIONS
Bilateral simultaneous minimally invasive total hip arthroplasty using a modified two-incision technique gave satisfactory clinical, radiological, and functional results. Efforts should be made to prevent perioperative periprosthetic fractures.
