Robot-Assisted vs. Manual Knee Replacement for Osteoarthritis
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial compares two methods of knee replacement surgery for individuals with knee osteoarthritis. One method involves robotic assistance (Total Knee Robotically-Assisted), while the other relies on the surgeon performing the procedure manually. The trial aims to determine any differences in knee function following each type of surgery. It may suit those with osteoarthritis in one knee who are considering knee replacement surgery. As an unphased trial, it provides a unique opportunity to explore innovative surgical techniques that could improve recovery and knee function.
Will I have to stop taking my current medications?
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 robot-assisted knee replacement is safe for osteoarthritis patients?
Research shows that robot-assisted knee replacements are generally safe and may offer benefits over traditional methods. Studies have found that this robotic technique causes less damage to the soft tissues around the knee, which is important because less tissue damage often leads to a smoother recovery.
In one study, patients who underwent robotic knee surgery lost about 23.7% less blood compared to those who had manual surgery. Losing less blood can reduce the need for a blood transfusion. However, some areas of the knee experienced more cases of soft tissue injuries.
Overall, patients handle robot-assisted knee replacement well. These findings suggest that while some risks exist, the benefits could make recovery easier for many people. Discussing all options with a medical professional before deciding on surgery is always advisable.12345Why are researchers excited about this trial?
Researchers are excited about robotically-assisted knee replacement because it offers a new level of precision and customization compared to traditional manual surgeries. Unlike standard procedures where the surgeon directly handles the instruments, this technique uses a dedicated surgical robot to assist in making precise bone cuts. The robot ensures that the surgery aligns perfectly with the planned surgical strategy, potentially leading to better outcomes, faster recovery, and improved joint function for patients with osteoarthritis.
What evidence suggests that robot-assisted knee replacement is effective for osteoarthritis?
This trial will compare robot-assisted knee replacements with manual knee replacements for osteoarthritis. Studies have shown that robots in total knee replacements can yield better results than traditional methods. Research indicates that this approach allows for more precise placement of knee implants, improving joint function and alignment. Patients have reported positive outcomes from robotic surgeries, with improvements observed over time. Although researchers continue to study the long-term benefits, early results suggest this method could enhance recovery and satisfaction. Overall, robot-assisted knee replacements offer promise for those with osteoarthritis requiring surgery.14678

Trial Overview
The study compares robot-assisted total knee arthroplasty (replacement) to the traditional manual method to see if there's a difference in how well patients do after surgery.

Experimental Treatment
Active Control
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.
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.
