Comparison of Functional Outcome in Patients After Hip Arthroplasty Depending on Surgical Approach

October 5, 2021 updated by: Artur Stolarczyk, Medical University of Warsaw

Comparison of Early Objective and Subjective Outcome in Patients After Hip Arthroplasty, Operated From Direct Anterior, Posterolateraland Anterolateral Approach: Prospective Randomized Clinical Trial

The aim of the study will be to compare functional outcomes of the two surgical hip approaches in total hip arthroplasty: anterior, posterolateral and anterolateral. Surgical approach may have influence on patients functional outcome.

Study Overview

Detailed Description

Patients with primary hip osteoarthritis will be included in a randomized controlled trial and assigned to total hip arthroplasty using one the of hip approaches: anterior or anterolateral. Subjects will be assessed preoperative and 3 and 12 moths postoperative.

Biomechanical gait parameters will be collected using tree-dimensional motion analysis system "BTS SMART".

Evaluation of the function of the middle gluteal muscle with superficial EMG (sEMG) percutaneous surface electromyography. Fatigue assessment (mean frequency and amplitude) of the gluteus medius muscle during isometric muscle contraction.

Balance and coordination as well as fall risk will be assessed with use of dynamometric Biodex Balance platform. The study will determine the values of individual indicators: general stability index (OWS), anterior-posterior stability index (APW), the median lateral stability index (MLW) and the fall risk index (RU).

Subjective assessment will be conducted with use of Visual Analogue Scale, WOMAC Index, Oxford Hip Score, The Short Form-36 (SF-36) and Harris Hip Score

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in biomechanical gait parameters
Time Frame: from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
Done by a biomechanics lab for patients to test their hip movements
from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
Gluteus medius muscle fatigue
Time Frame: from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
Surface Electromyographic analysis performed for testing gluteus medius activity
from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
Change from baseline in Hip disability and Osteoarthritis Outcome Score (HOOS) activities of daily living (ADL)
Time Frame: from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively

This asks the patient how their hip functions during their daily life. It has 5 subscales measuring Pain, Symptoms, ADL, Sports/Recreation and Quality of Life (which is calculated using all the subscores). Each subscale is calculated using the mean score, with each score range being from 0 to 4. The subscore is normalized such that the lower the number the more extreme the problem is. To calculate Quality of Life, the mean of the other 4 subscores are taken to calculate the score.

from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
Time Frame: from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
This measures health status as it relates to the hip. There are 3 subscales, pain which score ranges from 0-20, stiffness range from 0-8, physical function ranging from 0-68. The total score is just added up from the subscales.
from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
Change in Oxford scale
Time Frame: from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
The Oxford scale is a physiotherapist objective-rated scale to asses muscle strength against the resistance. It is graded from 0 (flicker of movement) to 5 (Through full range actively against strong resistance)
from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
Change in SF-36 scale
Time Frame: from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
The SF-36 is a participant self-rated questionnaire that is a general measure of perceived health status comprising 36 questions, which yields an 8-scale health profile. The vitality sub-score assesses energy and fatigue, and ranges from 0 (worst) - 100 (best).
from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
Change in Visual Analog Scale (VAS) scale
Time Frame: from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
To measure pain. This is a line with left most end representing no pain with the rightmost representing extreme pain. The participant puts a line where they feel that day and it is measured with a ruler to determine score out of 100. The line is 100mm long.
from baseline (can be measured anytime to a maximum of one month before surgery) to 3 and 12 months post-operatively
