Knee replacement. Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. It is most commonly performed for osteoarthritis,[1] and also for other knee diseases such as rheumatoid arthritis and psoriatic arthritis.
Partial knee replacement surgery is where they replace one side of the knee joint, usually due to damage caused by arthritis. Most commonly, it is the inner side of the knee that needs replacing. It is also known as a unilateral knee replacement or uni knee.artial knee replacement surgery is carried out either under a general anaesthetic or a spinal anaesthetic. General anaesthetic: you are put to sleep for the duration of the operation. Spinal anaesthetic (epidural): numbs the body below the waist and you are also given medicine to make you sleepy.
