Study Details

Study Description

Brief Summary

This study will explore if there are any difference in functional outcomes between two different surgical procedures for total knee replacement: robot-assisted versus manually-executed total knee arthroplasty.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Total Knee Robotically-Assisted
N/A

Detailed Description

Although total knee arthroplasty (TKA) is an effective treatment for end-stage knee arthritis, improvements in surgical technique remain a necessity. Contemporary designs have bolstered durability, but longer life expectancies have placed an even greater emphasis on survivorship. Additionally, patient satisfaction remains an issue.

A prospective randomized clinical trial (RCT) is proposed to compare robotically-assisted versus manually executed primary (TKAs). This study is designed to address the major short-term clinically important issues between the two types of procedures with special emphasis on functional outcome. Patients will be randomized to receive either a robotically-assisted or a manually-executed primary TKA.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Total Knee Robotically-Assisted

The intervention is then performed with a new device and surgical procedure. At first the femur and the tibia are fixed to the operating table with a special clamp and the knee bones are exposed with the standard technique; then the surgeon digitizes the shape of the joint and the computer transfers the planned surgical strategy to a dedicated surgical robot. Resections are performed by the surgeon on a constrained guide held by the robot.

Procedure: Total Knee Robotically-Assisted
The surgeon digitizes the shape of the joint and the computer transfers the planned surgical strategy to a dedicated surgical robot. Resections are performed by the surgeon on a constrained guide held by the robot.

No Intervention: Total Knee Manual-Executed by Surgeon

Your orthopaedic surgeon will remove the damaged cartilage and bone, and then position the new metal and plastic implants to restore the alignment and function of your knee.
