What is a knee joint?
Knee is a complex joint that connects thigh bone (femur) to the leg bone (tibia). In addition to that, knee cap (patella) articulates with femur.
Normally, joint surfaces are lined with very fine articular cartilage, which ensure movement with minimum friction. There are also other specialised structures inside the knee like the meniscus, which help in knee motion and act as shock absorbers.
What causes knee pain?
If for any reason the cartilage gets worn out, the surface of the joints become rough and movement may become painful.
Joint cartilage usually wears out because of the ageing process, leading to osteoarthritis. Wearing out can also be caused by different forms of arthritis, such as rheumatoid arthritis, post injury arthritis, etc.
How is knee pain treated?
In early stage of knee arthritis, pain can usually be controlled with weight reduction, physiotherapy and mild medication.
During end stage of arthritis, when degeneration or arthritis advances too much, there is severe decrease in joint space and consequently significant amount of pain while walking, getting up from chair, and sometimes even while resting. In such a scenario, surgery may be required to replace the knee.
What is knee replacement?
Knee replacement is a misnomer. It is better to describe it as knee resurfacing or knee arthroplasty. The procedure involves removal of worn out cartilage along with a bit of bone. Then with special tools (jigs), a shape is created to properly fit in an implant. Special bone cement is used to fix the implant to the bone.
Implants help the joint move with very low friction, almost like the original joint. They are metallic on one side and special plastic on the other. At Nanavati orthopaedics joint centre , implants from various international companies are available and only the best are used for such procedures.
