Partial Knee Replacement
One cause of discomfort and stiffness in knees is wear and tear on the cartilage that cushions your knee bones. If this wear is confined to just a portion of your knee, then you might be a good candidate for a partial knee replacement.
If the osteoarthritis in your knee is limited to a single area, you may only need a partial knee replacement.
Your knee is divided into three compartments: the medial compartment (the inside part of the knee), the lateral compartment (the outside part), and the patellofemoral compartment (the front of the knee between the kneecap and thighbone).
With a partial knee replacement, only the damaged compartment is replaced with metal and plastic. The healthy cartilage and bone in the rest of the knee is left untouched.
The advantages of partial knee replacement over total knee replacement include:
- Quicker recovery, smaller incisions
- Less pain and faster recovery
- Less trauma to the bone and surrounding tissue
- May allow the knee to bend better
Because the healthy bone, cartilage, and ligaments are kept, most patients also report that a partial knee replacement feels more" natural" than a total knee replacement.
