What is Knee Replacement Surgery?

● Knee replacement surgery is a surgery in which the impaired knee joint is replaced by an artificial joint.

● The most common condition leading to knee replacement is arthritis.

● The surgery usually lasts 2 hours and is performed under general or spinal anesthesia.

● Different types of implants used for knee replacement are metal on metal, ceramic on ceramic, and ceramic on polyethylene.

● Earlier, the incision made for performing knee replacement surgery used to be 20-25 cm long, but now with minimally invasive surgery, the cut size has been reduced to 10-15 cm.
