If you’re one of the millions of Americans suffering from knee pain or stiffness caused by degenerative joint disease (including osteoarthritis, traumatic arthritis, or avascular necrosis), rheumatoid arthritis or post-traumatic arthritis and have not had adequate relief with conservative treatment options, like bracing, medication or joint fluid supplements, then ask your doctor if this is right for you.
The first step is patient-specific surgical planning. Before surgery, a CT scan of your knee is taken to develop a 3D virtual model of your unique joint. Your doctor uses this model to evaluate your bone structure, disease severity, joint alignment and even the surrounding bone and tissue, so they can determine the optimal size, placement and alignment of your implant.
During the procedure, the surgeon uses the robotic arm to precisely shape the surrounding bone before placing the implant. Real-time video images provide visual reinforcement, which helps surgeons navigate hard-to-see areas.
At the same time, the system uses the CT image data to create a predefined, three-dimensional “envelope” of space in which the surgeon works. The robotic arm will only operate in that predefined space, so there is no chance of an instrument slipping and injuring adjacent tissues.
Throughout your procedure, the robot provides real-time data to your surgeon. This allows them to continuously assess the movement and tension of your new joint, and adjust your surgical plan if desired.
With the diseased bone gone, your implant is placed into the knee joint.
Most patients will spend one night in the hospital after a total knee replacement. Healthy and motivated patients could go home on the same day as surgery. This rapid recovery is one of the biggest advancements in knee replacement. Having a good team at home to help your recovery is important.
Most patients will use a walker for a week or two as they get more comfortable walking on their new knee. You will transition to a cane or crutch for a week or two. By the time you come to your first appointment you may be using your cane for longer walks but you may not be using it much at all. Physical therapy is arranged although most patients don’t need much therapy. Walking is the best exercise after knee replacement and your range of motion will improve quickly.
Recovery after joint replacement takes a full year, however, 80% of your recovery will happen in the first 3-4 months. When you are fully recovered from your knee replacement there will be no restrictions on your activity and you can resume any and all activities that you wish.
