Partial Knee Replacement can be considered at any age
Partial Knee Replacement Frequently Asked Questions
There are 2 main types of surgery:
• total knee replacement – both sides of your knee joint are replaced
• partial (half) knee replacement – only 1 side of your joint is replaced in a smaller operation with a usually shorter hospital stay and recovery period
Multiple studies show that a majority of patients who are appropriate candidates for the procedure have good results with unicompartmental knee replacement.
The potential advantages of partial knee replacement over total knee replacement include:
• Quicker recovery
• Less pain after surgery
• Less blood loss
Also, because the bone, cartilage, and ligaments in the healthy parts of the knee are kept, many patients report that a unicompartmental knee replacement feels more natural than a total knee replacement. A unicompartmental knee may also bend better.
The disadvantages of partial knee replacement compared with total knee replacement include:
• Slightly less predictable pain relief
• Potential need for more surgery. For example, a total knee replacement may be necessary in the future if arthritis develops in the parts of the knee that have not been replaced.
• Higher revision rate – studies have shown that partial knee replacements have a higher redo, or revision rate compared to total knee replacements
If you have arthritis mainly in one compartment (area) of the knee then you may be a candidate for partial knee replacement. It is important to discuss your own personal circumstances with your surgeon so that you can make the right informed choice.
