On-Table vs Off-Table Techniques for Hip Replacement
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial compares two methods for hip replacement surgery to determine which one is more effective. The "On Table Group" uses a special table to assist during surgery, while the "Off Table Group" relies on the surgeon to position the leg. The trial aims to identify the more efficient and effective approach. Individuals undergoing a first-time hip replacement on one hip and eligible for spinal anesthesia may be suitable candidates for this study. As an unphased trial, it offers participants the chance to contribute to advancements in surgical techniques for hip replacement.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that these techniques are safe for hip replacement?
Research has shown that both the "on-table" and "off-table" methods for hip replacement surgery are safe. One study found that the direct anterior approach (DAA) for hip replacement can be performed safely using either a special traction table or a regular table. This indicates that patients generally handle the surgery well, regardless of the table used.
Additional research confirms that the DAA, with either method, is a safe and effective choice for hip replacement. This technique is used worldwide, and many patients have undergone these surgeries without major problems.
Prospective participants in a study for these techniques can feel confident that both methods are well-established and have been proven safe for patients.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it compares two different techniques for hip replacement surgeries: the "on-table" and "off-table" methods. The "on-table" technique uses a specialized traction table to position the patient's leg, which is standard in many hospitals. In contrast, the "off-table" technique relies on a regular operating table, with the surgeon manually positioning the leg. This could potentially reduce costs by eliminating the need for specialized equipment and extra staff. By comparing these methods, researchers hope to determine which approach is more efficient and effective for patients undergoing hip replacement surgery.
What evidence suggests that this trial's techniques could be effective for hip replacement?
This trial will compare the "on-table" and "off-table" techniques for hip replacement surgery. Research has shown that both methods are effective and safe. Studies have found that the "off-table" technique may reduce setup and operation time, allowing for a quicker surgery process without compromising safety. Meanwhile, the "on-table" group will undergo surgery using a special traction table, which is also efficient and safe. Both methods are widely used globally and have proven to lead to good patient outcomes.24678

Are You a Good Fit for This Trial?
This trial is for adults over 18 who need a primary unilateral total hip arthroplasty (hip replacement) due to osteoarthritis. They must be able to consent and pass medical clearance. It's not for those with a BMI over 40, HbA1c levels above 8.0, pregnant women, active smokers, or anyone needing bilateral procedures or unable to have spinal anesthesia.Inclusion Criteria

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.

Experimental Treatment
Active Control
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. 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.

The control group will be using the first method, which 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.
