What is a Knee Joint Replacement?

A knee joint replacement is a surgical treatment where an injured or damaged knee is replaced with an artificial joint or a prosthesis. It is also known as knee arthroplasty.

The artificial joint or prosthesis is usually made of metal, metal alloys, plastics, and polymers. Depending upon a patient’s personal information, like, age, weight, activity level, and overall medical history, the doctor will suggest the kind of prosthetic that the concerned patient might need.

  3. A urinary catheter may be inserted. 
  4. You will be under anaesthesia with your heart rate, blood pressure, blood oxygen level during the procedure being continuously monitored. 
  5. The procedure can last between 1-2 hours where the surgeon will make a cut in your knee, and while pulling the skin and muscle back, remove the damaged cartilage or bone.
