Total Hip Arthroplasty (THA) Surgical Techniques Comparing the Direct Anterior Approach to the Posterior Approach
Prospective Randomized Single Center Clinical Evaluation of THA Surgical Techniques Comparing the Direct Anterior Approach to the Posterior Approach
Study Overview
Status
Conditions
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.

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.
