          joint replacement surgery
                                 joint replacement surgery involves removal of the worn cartilage from both sides of the joint, followed by resurfacing of the joint with a metal and plastic replacement implant that looks and functions much like your normal joint. Although nearly every joint in the body can be replaced, most replacement surgeries involve the hip or knee. Over the last 30 years, improved surgical techniques and new implant materials have been developed, making total joint replacement one of the most reliable and durable procedures in any area of medicine. computer assisted joint-replacement surgery has substantially increased accuracy of the surgery. joint replacement surgeries for knee, hip, shoulder, ankle and elbow.



                                 Knee replacement, or knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability.
Knee replacement surgery can be performed as a partial or a total knee replacement. In general, the surgery consists of replacing the diseased or damaged joint surfaces of the knee with metal and plastic components shaped to allow continued motion of the knee.
It is most commonly performed for osteoarthritis, and also for other knee diseases such as rheumatoid arthritis and psoriatic arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long-standing osteoarthritis, the surgery may be more complicated and carry higher risk. Osteoporosis does not typically cause knee pain, deformity, or inflammation and is not a reason to perform knee replacement.



                                Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant. Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures. A total hip replacement (total hip arthroplasty) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is currently the most common orthopaedic operation, though patient satisfaction short- and long-term varies widely.



                                 Elbow replacement is surgery to replace the elbow joint with artificial joint parts (prosthetics).
The elbow joint connects two bones:
      The humerus in the upper arm
      The ulna in the lower arm
The artificial elbow joint has two stems made of high-quality metal. A metal and plastic hinge joins the stems together and allows the artificial joint to bend. Artificial joints come in different sizes to fit different size people. You will receive general anesthesia before surgery. This means you will be asleep and pain-free during surgery. Some patient may also receive regional anesthesia. You will also be given medicine to help you relax.
Your surgeon will make an cut on the back of your arm to show your elbow joint. The damaged tissue and parts of the arm bones that make up the elbow joint are removed. A drill is used to make a hole in the center of the two arm bones. The end of the artificial artificial elbow joint are placed into each bone. They are connected with a hinge. The tissue around the elbow is repaired. The wound is closed with stitches, and a bandaged is applied. Your arm may be placed in a splint to keep it stable.



                                 Shoulder replacement surgery, the damaged parts of the shoulder are removed and replaced with artificial components, called a prosthesis. The treatment options are either replacement of just the head of the humerus bone (ball), or replacement of both the ball and the socket (glenoid). Shoulder replacement is a surgical procedure in which all or part of the glenohumeral joint is replaced by a prosthetic implant. Such joint replacement surgery generally is conducted to relieve arthritis pain or fix severe physical joint damage.
Shoulder replacement surgery is an option for treatment of severe arthritis of the shoulder joint. Arthritis is a condition that affects the cartilage of the joints. As the cartilage lining wears away, the protective lining between the bones is lost. When this happens, painful bone-on-bone arthritis develops. Severe shoulder arthritis is quite painful, and can cause restriction of motion. While this may be tolerated with some medications and lifestyle adjustments, there may come a time when surgical treatment is necessary.



                                 Ankle replacement, or ankle arthroplasty, is a surgical procedure to replace the damaged articular surfaces of the human ankle joint with prosthetic components. This procedure is becoming the treatment of choice for patients, replacing the conventional use of arthrodesis, i.e. fusion of the bones. The restoration of range of motion is the key feature in favor of ankle replacement with respect to arthrodesis. However, clinical evidence of the superiority of the former has only been demonstrated for particular isolated implant designs.
