Knee "resurfacing" is a procedure in which the surface of the bones is actually replaced.
The damaged cartilage surfaces at the ends of the femur and tibia are removed along with a small amount of underlying bone. The removed cartilage and bone is replaced with man-made components that recreate the surface of the joint.
These parts may be cemented or "press-fit" into the bone. The under-surface of the patella (kneecap) is cut and resurfaced with a plastic button. Some surgeons do not resurface the patella, depending upon the case. A medical-grade plastic spacer is inserted between the metal components to create a smooth gliding surface.
MAKOplasty is a robotic-assisted partial knee resurfacing procedure designed to relieve pain and improve range of motion in knee joints that have a breakdown or loss of cartilage due to early to mid-stage osteoarthritis. Cartilage is a protein substance that acts as a cushion between the bones of a joint and when worn away, the bones rub together. The procedure precisely targets the damaged area and resurfaces your knee while sparing healthy bone and ligaments surrounding it. The procedure helps the surgeon position the knee implant for a natural-feeling result and less downtime for you. Small incisions are made in your thigh bone and shin bone. The procedure is for people who have damage in one or two compartments of the three knee compartments. If your surgeon discovers more damage in your knee than seen in pre-operative X-rays and CT scan, a total knee replacement surgery may be required.
