A New Treatment Option for Knee and Hip Replacement

Your joints are involved in almost every daily activity. For those with osteoarthritis, the condition over time may wear away at your cartilage and cause pain, as bone rubs against bone. Knees and hips are most frequently affected by this condition. When pain medication and other treatments no longer work, you may face the option of joint replacement surgery.

Orlando Health has a new tool with a proven track record of improving patient outcomes for these surgeries. With minimally invasive robotic-assisted technology, surgeons can restore diseased joints with implants designed to accurately replace your lost cartilage. During the procedure, implants are custom-designed by the surgeon to fit a patient’s unique anatomy and to minimize the wear and loosening that can occur with implants used in manual surgery, says Jeffrey Petrie, MD, an orthopedic surgeon with Orlando Health Jewett Orthopedic Institute who uses the robotic technology.

Patient Benefits

More than 50,000 hip and knee procedures have been performed using minimally invasive robotic surgery since 2006. The patient benefits are documented in extensive clinical research that includes 50 peer-reviewed clinical publications and 300 scientific abstracts.

When compared to traditional joint replacement surgery, research shows that patients who undergo minimally invasive robotic surgery experience more accurate implant placement. This can result in less pain for patients after surgery.

Minimally Invasive Partial Knee Replacement

Minimally invasive robotic partial knee replacement is a surgical procedure that helps relieve pain caused by arthritis in any of the three compartments of the knee. With a 3D model of your knee, the surgeon resurfaces its diseased portion, saving as much healthy bone and surrounding tissue as possible. The surgeon guides the robotic arm while preparing the knee socket and positioning the implant to precisely fit your anatomy.

Minimally Invasive Full Hip Replacement

When replacing a diseased hip, minimally invasive robotic-arm assisted surgery uses a similar process with the surgeon positioning a custom-designed implant based on a CT scan and 3D virtual model of the patient’s unique hip anatomy.

The procedure provides surgeons with a clear picture of the hip joint and pelvis tilt to perform accurate implant surgery. The surgeon is able to guide the robotic arm during the procedure based on an individualized patient plan. This helps the surgeon focus on removing diseased bone, preserving healthy bone and positioning the hip implant for the patient’s specific anatomy.
