Total knee replacement is often the last option when conservative options fail to relieve the pain and retard the progression of joint damage in patients with severe arthritis. Knee replacement surgery involves replacing the damaged cartilage and bone from the surface of the knee joint with a synthetic implant.
A custom knee replacement is a novel technology in total knee replacement that uses an MRI scan of the knee to model your knee and then make custom designed cutting guides. The procedure begins before your surgery with a MRI scan and X-rays to make exact measurements of your knee. Computer software transforms that MRI image into a 3-D model of your arthritic knee and then virtually rectifies any deformity so as to restore the knee to its pre-arthritic condition. Specially designed cutting guides are then made, which allows the surgeon to preserve more of the bone and ligaments to accept the knee replacement implant.
Benefits of a custom knee replacement include:
- Minimally invasive technique
- Minimal blood loss
- Quicker recovery
- Precision fit and knee alignment
- Shorter operative time
- Less chance of infection
- Less postoperative pain
- Greater range of motion
- Quicker return to normal activities
You are not a candidate for custom knee replacement if you have had previous corrective knee surgery or injured ligaments. Patients with knee implants, pacemakers or vascular clips who are not eligible for an MRI scan are not eligible for a custom knee replacement.
