What is Joint and knee replacement surgery?
Joint Replacement Surgery is one of the most important procedures of orthopedic surgery in which the arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment only for people with severe dysfunction that cannot be alleviated by less-invasive therapies like exercise, weight control and medications.
This surgery is conducted to accomplish the following purposes:
- To relieve pain
- To restore range of joint motion
- To correct deformity
- To improve walking ability, leading to subsequent improvement of muscle strength
The appropriate procedural measures and surgeries are decided individually by surgeons, and can vary from person to person. These decisions are based on various factors like age, bone strength, joint shape and condition, general health, weight, activities, eating habits etc.
The most common surgeries are Hip and Knee replacement surgeries.
Knee Replacement Surgery is the procedure to replace weight-bearing surfaces of the damaged knee joint with metal and plastic surfaces shaped to relieve pain and disability. This allows continued motion of the knee and improves functionality and mobility.
The new artificial knee is called Prosthesis or an implant- and is routinely made of stainless steel, cobalt, chrome alloys or titanium. Bone cement is used to anchor the prosthesis into the bone, while durable wear-resistant polyethylene (plastic) is used for weight bearing surfaces.
The surgeries are most commonly performed for knee diseases like Osteoarthritis (OA) and Rheumatoid Arthritis (RA). Knee replacements are now being introduced to younger people due to their long lasting traits.
