Knee Preservation Surgeries
Osteoarthritis can develop when the bones of your knee and leg do not line up properly.
This can put extra stress on either the inner (medial) or outer (lateral) side of your knee. Over time, this extra pressure can wear away the smooth articular cartilage that protects the bones, causing pain and stiffness in your knee.
Advantages and Disadvantages
Knee Osteotomy has three goals:
- To transfer weight from the arthritic part of the knee to a healthier area
- To correct poor knee alignment
- To prolong the life span of the knee joint
One advantage of the procedure is that, by preserving your own knee anatomy, a successful osteotomy may delay the need for a joint replacement for several years.
Another advantage is that there are no restrictions on physical activities after an osteotomy—you will be able to participate in your favorite activities, even high-impact exercise.
Osteotomy does have disadvantages.
For example, pain relief is not as predictable after osteotomy compared with a partial or total knee replacement and recovery from osteotomy is typically longer and more difficult because you may not be able to bear weight on your operated knee right away.
In some cases, having had an osteotomy can make later knee replacement surgery more challenging. Because results from a total knee replacement and partial knee replacement have been so successful, knee osteotomy has become less common. Nevertheless, it remains an option for many patients.
