Mako can be used for partial knee replacement (PKR), which is a procedure designed to relieve the pain caused by joint degeneration due to osteoarthritis (OA) in one or two compartments of the knee. BID-Plymouth Orthopedic Surgeons have been performing Partial Knee Replacements since 2013 and have seen great results. By selectively targeting the part of your knee damaged by OA, orthopedic surgeons can replace the diseased part of your knee while helping to spare the healthy bone and ligaments surrounding it. The Mako technology provides surgeons with a patient-specific 3-D model to pre-plan your partial knee replacement. During surgery, they guide the Mako robotic-arm based on your patient-specific plan. This allows them to remove only the diseased bone, preserving healthy bone and soft tissue, and assists them in positioning the implant based on your anatomy.
