About this study

Official title: 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).

Read the 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.

Being tested

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Anterior Approach / Posterior ApproachProcedure or surgery

    compare results of total hip arthroplasty performed through either an anterior or posterior surgical approach

  • Anterior versus Posterior Approach for total hip replacementProcedure or surgery

    Compare results of total hip arthroplasty performed through either an anterior or posterior surgical approach

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Returning to Quality of Life by Using Either Anterior Approach Versus Posterior Approach

    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.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

A study testing Anterior Approach / Posterior Approach and Anterior versus Posterior Approach for total hip replacement in people with Osteoarthritis of the Hip, run by Barrett, William, M.D. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Aug 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Returning to Quality of Life by Using Either Anterior Approach Versus Posterior Approach (time frame: 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Aug 2019.
