Clinical Trial Summary

Recent increased interest in tissue-sparing and minimally invasive arthroplasty has given rise to a sharp increase in the utilization of direct anterior total hip arthroplasty.

Description:

• Purpose: The direct anterior approach to the hip has been suggested to have several advantages compared to previously classical approaches. However, no studies focused on the effects of these different surgeries on patients' perception recovery and walking efficiency according the initial physical fitness. Therefore, the purpose of this study is to compare the effects of surgical procedures on perceptual walking skills and efficiency according to the patients' physical fitness.

• Abstract : Some earlier studies report differences between surgery types in self- reported mobility, functional recovery and residual hip pain. The direct anterior approach to the hip has been suggested to have several advantages compared to previously popular approaches through its use of an intra-muscular and intra-nervous interval between the tensor fasciae latae and sartorius muscles. However, patients' physical fitness, postural response and perceptual walking skill relation was not taking account. 80 patients will be tested, one before and at various times after hip surgery. In randomized conditions, our patients will be divided in two groups, according the surgery approaches and their physical fitness. All patients performed a Performance-Oriented Mobility Assessment Walking test with and without step and the PMA, Harris, Oxford 12 and Womac scores will be evaluated before, 3 weeks, 6 weeks, 3 months and 1 year after the surgery. During the Performance-Oriented Mobility Assessment Walking test, self-reported walking capacity, rating of exertion perception and walking parameters will be measured.

• Exclusion Criteria:

• No health coverage

• Hip Arthropathy
• Joint Diseases

Intervention

Other:
• The posterolateral approach
The posterolateral approach was used for implantation among patients in lateral position. This approach goes through the gluteus maximus, the piriformis and superior gemeli muscles are detached and later reattached to bone
• Direct anterior technique
patients were fixed in a supine position, a small entry incision was made in the vessel free interval between the tensor fasciae latae and the sartorius muscles and the prosthesis socket were put in place. Via a second dorsal incision, after releasing the external rotators, the prosthesis stem and ball were implanted and the two parts of the prosthesis were attached
