What is Partial Knee
Partial knee replacement (PKR) is a surgical procedure that helps relieve arthritis in one or two of the three compartments of the knee.
With PKR, only the damaged area of the knee joint is replaced, which may help to minimize trauma to healthy bone and tissue. Stryker has worked with surgeons to develop innovative products to be utilized in Partial Knee Replacement surgery. Stryker’s Robotic-Arm Assisted partial knee replacement procedure is designed to relieve the pain caused by joint degeneration due to osteoarthritis (OA).
There are three types of Partial Knee Replacement.
- Unicondylar Knee Replacement is a procedure that replaces only the single affected compartment of the knee, either the medial or lateral compartment.
- Patellofemoral Knee Replacement is a procedure that replaces the worn patella (the kneecap) and the trochlea (the groove at the end of the thighbone).
- Bicompartmental Knee Replacement is a procedure that replaces two compartments of the knee, the medial and patellofemoral compartments.
