Isokinetic Performance and Function After Total Hip Arthroplasty

Not Applicable

Completed

• Conditions: Hip Osteoarthritis
• Interventions: Procedure: hip arthroplasty

• Registration Number: NCT04640740
• Lead Sponsor: Gulhane Training and Research Hospital

Brief Summary

There are ongoing debates on the effects of the surgical approach on outcome after total hip arthroplasty. It was hypothesized that with the anterolateral approach, trauma to the abductor arm can be occured and related detrimental effects can diminish the post-operative outcomes. In this first randomized controlled trial in the literature on this subject, isokinetic performance and patient-reported functional outcomes were evaluated in patients undergoing total hip arthroplasty. with a posterior approach (PA) and a anterolateral approach (ALA), at 6 and 12 months postoperatively.

Detailed Description

Patients undergoing total hip arthroplasty are randomized to posterior approach (PA) and anterolateral approach (ALA) groups. The patients are evaluated preoperatively and at 6 and 12 months postoperatively, with flexion, extension and abduction strength measurements and the Harris Hip Score (HHS). The physiatrist performing isokinetic tests and the patients are blinded to the study groups.All data are calculated as mean and standard deviation values. The Student's t-test is used for statistical analysis of the patient data. Statistical calculations are performed using SPSS vn.22.0 software (IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY, USA).
