What is Minimally Invasive Knee Replacement Surgery?

In this procedure, the damaged or worn out surfaces of the knee joint are removed and replaced with a prosthesis, to reduce pain and regain mobility in the joint.
Why is Minimally Invasive Knee Replacement Surgery Done?
Minimally invasive knee replacement surgery may be required if there’s damage to the knee joint. It may occur due to various medical conditions, including –
- Osteoarthritis – The most common type of arthritis is called osteoarthritis. It is mostly associated with the wear and tear of cartilage due to age. As we grow old, the cartilage starts to wear away leading to bones rubbing against each other. This causes pain and stiffness in the knee joint.
- Osteonecrosis – In this condition, the blood supply to the thighbone or shinbone gets disrupted. This can lead to severe arthritis, and ultimately, destruction of the knee joint.
- Bone tumor in the knee joint – Sometimes, bone tumors such as osteosarcoma can develop in the thighbone or shinbone.
- Rheumatoid arthritis – This is an autoimmune condition wherein the synovial membrane becomes thick and inflamed, causing cartilage damage and ultimately, pain and stiffness in the knee joint.
- Fracture or injury of knee joint – Knee replacement surgery may be required in case of a severe fracture or injury to the knee joint.
