So you have been diagnosed with arthritis and your doctor will probably suggest surgery to fix the problem. Taking the decision to undergo a surgery is not a small matter. Here, we look at the different options for surgery and the procedures involved.


Total knee replacement surgery is undertaken to help relieve knee pain and increase knee function by resurfacing the bones that meet at the knee joint. The damaged portions of bone at the end of the femur (thigh-bone) and top of the tibia (shin-bone) is removed and replaced with prosthetic components. Some surgeries also resurface the back of the patella or kneecap.


A partial knee replacement surgery is carried out to replace only one part of a damaged knee. It can replace either part of the knee- the inside (medial) part, the outside (lateral) part or the kneecap part. Partial knee replacement surgery involves removing damaged tissue and bone in the knee joint. The damaged area is replaced by implanting a prosthetic.


Osteotomy means "cutting of the bone" to fix the knee’s alignment and reduce chronic arthritis pain. In a knee osteotomy, either the tibia (shinbone) or femur (thighbone) is cut and then reshaped to relieve pressure on the knee joint. Knee osteotomy is used when a patient has unilateral knee arthritis or early-stage osteoarthritis that has damaged just one side or compartment of the knee joint. The two most common types of knee osteotomies are high tibial osteotomy (reshaping of the shin bone) and femoral osteotomy (reshaping of the thigh bone).


Knee arthroscopy is a surgical procedure where the surgeon makes a small incision and inserts a tiny camera (arthoscope) to view the knee joint rather than making larger incisions. This results in reduced pain for patients, less joint stiffness and often shortens the time to recover and get back to regular physical activities. Arthroscopy is used to diagnose and treat a wide range of knee problems and guide miniature surgical instruments.

Joint replacements are generally successful and help relieve pain. The extent to which movement may improve will depend on how severe your arthritis is and how strong the muscles surrounding your joints are. Opt for a surgery option after a thorough research and consultation to reap the maximum benefits
