Total Hip Arthroplasty (THA) Surgical Techniques Comparing the Direct Anterior Approach to the Posterior Approach

July 25, 2019 updated by: William Barrett, M.D., Barrett, William, M.D.

Prospective Randomized Single Center Clinical Evaluation of THA Surgical Techniques Comparing the Direct Anterior Approach to the Posterior Approach

The purpose of this study is to compare the short term effectiveness and return to function of subjects undergoing primary Total Hip Arthroplasty using an Anterior Approach (incision on the front part of the hip joint) versus Posterior Approach (incision over back part of the hip joint).

Study Overview

Detailed Description

The anterior approach may provide better early post-operative outcomes because there are fewer muscles at the front of the hip so the surgeon works between them rather than cutting through muscle fibers. However, the anterior approach is more difficult to access so usually requires a specialized table.

The posterior approach is easier to access, but the incision cuts through muscle fiber. This may lengthen recovery time. However, a specialized table, which can be quite expensive, is often not required.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Anterior Approach Total Hip
Total hip arthroplasty performed through an anterior surgical approach. Compare results of total hip arthroplasty performed through either an Anterior or Posterior Surgical Approach
compare results of total hip arthroplasty performed through either an anterior or posterior surgical approach
Active Comparator: Posterior Approach Total Hip
The additional arm is the posterior approach total hip, which the Anterior Approach is being compared too. Compare results of total hip arthroplasty performed through either an Anterior or Posterior Surgical Approach.
Compare results of total hip arthroplasty performed through either an anterior or posterior surgical approach

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Returning to Quality of Life by Using Either Anterior Approach Versus Posterior Approach
Time Frame: 5 years
Harris Hip 5-Year Total Score Change from Baseline. The Harris Hip score gives a maximum of 100 points. Pain receives 44 points, function 47 points, range of motion 5 points, and deformity 4 points. Function is subdivided into activities of daily living (14 points) and gait (33 points). The higher the Harris Hip score, the less dysfunction.This outcome measure has been validated for joint replacement surgery for peer reviewed orthopedic literature.
