Unicondylar Knee Replacement
In this operation only half of the knee is replaced with an artificial joint. This is suitable to only those selective groups of patients where only one half of the knee is involved. Instead of replacing the whole knee as in total knee replacements, only worn out compartment of the knee is replaced. This operation can’t be done in severely deformed knees, unstable knees and if whole knee is involved. Advantages include.
Lesser duration for the operation
- Smaller cut in the skin
- Lesser bone is removed and the other half of the joint will be functioning normally. This leaves normal sensation, structures etc intact.
- Shorter hospital stay
- Shorter recovery period
- Blood transfusion rarely required
- Better movement in the knee
- Feels more like a normal knee
- Less need for physiotherapy
- Able to be more active than after a total knee replacement.
The big advantage is that if it is not successful due to any reason, it can be revised to a total knee replacement without much difficulty.
