During a knee replacement procedure, the damaged bone and cartilage is replaced with prosthetic components made from materials such as metals and plastics
When a patient feels severe knee pain and suffers some kind of disability as a result, a knee replacement may be required. Severe knee pain can be caused by a number of factors such as osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis, which is often due to previous knee injuries.
One of the most common reasons your orthopaedic surgeon may recommend a total knee replacement is if you suffer from severe osteoarthritis. Osteoarthritis is a degenerative disease resulting from the degeneration of the bone, cartilage, and tissue lining the joint. This in turn reduces the effective joint space and lubrication between the bones. This can often cause significant pain, as well as knee stiffness and swelling. In extreme cases, this may result in knee deformities, like the varus knee and valgus knee. Osteoarthritis is relatively common in patients over the age of fifty.
Rheumatoid arthritis, a chronic inflammatory joint disease, affects various joints in the body. The disease causes pain, and stiffness, and in some cases, deformity, due to the joint destruction which results from inflammation within the joint lining and inflammatory cells which are produced. This disease can affect the shoulders, hands, wrists, and knees.
Post-traumatic arthritis can also cause severe knee pain. This typically occurs after an injury like a dislocation or fracture. Additionally, preceding removal of damaged cartilage like the meniscis, may lead to arthritis some years later.READ MORE ABOUT THE SURGERY >>
