Trial Summary

What is the purpose of this trial?

The Direct Anterior Approach (DAA) is a common way to perform total hip arthroplasty. There are two main techniques to perform total hip replacement through the anterior approach. The first method is the "on-table" method, which uses a specialized surgical table, called a traction table. This table involves placing both feet in specialized boots that are then hooked up to the table, and allows for positioning of the operative leg with aid of the table. The major limitations associated with the traction table are the need for two additional staff members and the purchase of said table. The second method is the "off-table" method. In this method the patient is placed on a standard operating room table and the operative leg is manually positioned by the surgeon during the procedure . This obviates the need for the additional staff members or purchase of a specialized table. Both the "on-table" and "off-table" techniques are routinely used both worldwide and by our joint replacement specialists at Carilion Clinic. This study will aim to compare the efficiency and efficacy of performing the DAA for total hip arthroplasty utilizing either the "on-table" or "off- table" technique. Patients will be randomized to receive their total hip arthroplasty with either the "on- table" or "off-table" method.

Treatment Details

Interventions

  • Off Table Group
  • On Table Group
Trial Overview The study compares two techniques of total hip replacement using the Direct Anterior Approach: 'on-table' using a traction table that positions the leg versus 'off-table' where the surgeon manually positions the leg without special equipment. Patients will be randomly assigned one of these methods.

The Direct Anterior Approach (DAA) is a common way to perform total hip arthroplasty. There are two main techniques to perform total hip replacement through the anterior approach. The experimental group will be using the second method, which is the "off-table" method. In this method the patient is placed on a standard operating room table and the operative leg is manually positioned by the surgeon during the procedure . This obviates the need for the additional staff members or purchase of a specialized table.
