Unicondylar Knee Replacement (partial knee replacement)
A unicondylar knee replacement or a partial knee replacement may be an option for some patients. Approximately 10-15% of patients may have isolated arthritis to only one area of the joint, typically the inner-side of the knee. If deemed appropriate, these patients may benefit from a partial knee replacement rather than replacing the whole knee. Advantages of this type of surgery may be a shorter hospital stay, less post-operative pain, quicker return of strength, range of motion and activity, and less risk of blood clots. Because this surgery is a minor surgery as compared to a total knee replacement, many patients say that their knee feels more “normal” than after a total knee replacement. A potential disadvantage of a partial knee replacement may be the need to convert to a total knee replacement in the future, if the other side of the joint wears down.
