With arthritis of the knee, a partial knee replacement is typically recommended when non-surgical options have been unsuccessful. Partial knee replacement has the potential to be an outpatient surgery because it is less invasive, meaning you may be able to return home the same day as the procedure.
The surgeon will make a small Incision in the knee to access the impacted area. The arthritic segments of the femur (thighbone) and meniscus (cartilage between the thighbone and shinbone) will be removed along with some of the tibia (shinbone). Metal hardware is installed based on the side of the segment removed. Finally, plastic piece is inserted between the metal hardware to allow for a smooth range of motion and reduce wear on the hardware.
Partial knee replacement can prevent the spread of arthritis and has the potential to decrease the need for a total knee replacement in the future. In a majority of cases, the pain and pressure associated with arthritis decreases and mobility improves.
