What are the benefits of a bilateral knee replacement?
The benefit of simultaneous knee replacement is that the deformity of both the knees is corrected at once. The overall rehabilitation time is a shorter, and there is only one hospitalisation. Patients also require only one anesthesia and pain relief in both knees is at the same time.

Disadvantage / complication of bilateral knee replacements
While modern anesthesia and pain techniques have revolutionised knee replacement surgery and made it safe and reproducible, bilateral knee replacement is offered only to patients who are medically fit and have good heart and lung reserves.

Bilateral (both knees surgeries together) surgery should be performed only at specialised centres by experienced hands as it ought to be completed efficiently, in time and without compromising patients safety.
