Joint Replacement Surgery
Hip joint and knee joint replacements are helping people of all ages live pain- free, active lives.
Joints are formed by the ends of two or more bones connected by tissue called cartilage. Healthy cartilage serves as a protective cushion, allowing smooth and low-friction movement of the joint. If the cartilage becomes damaged by disease or injury, the tissues around the joint become inflamed, causing pain. With time, the cartilage wears away, allowing the rough edges of bone to rub against each other, causing more pain.
When only some of the joint is damaged, a surgeon may be able to repair or replace just the damaged parts. When the entire joint is damaged, a total joint replacement is done. To replace a total hip or knee joint, a surgeon removes the diseased or damaged parts and inserts artificial parts, called prostheses or implants.
Computer Assisted Hip and Knee Joint Replacement
Computer Assisted Surgery (CAS) technology allows the surgeon to simultaneously visualize two- or three-dimensional views of the patient's anatomy on a monitor, and provides real-time, intra-operative views of surgical instruments and the relative digital positioning of implantable devices.
Total Hip Replacement (THR)
Total hip replacement is a surgical procedure in which the damaged cartilage and bone is removed from the hip joint and replaced with artificial components. The hip joint is one of the body's largest weight-bearing joints, located between the thigh bone (femur) and the pelvis (acetabulum). It is a ball and socket joint in which the head of the femur is the ball and the pelvic acetabulum forms the socket. The joint surface is covered by a smooth articular cartilage which acts as a cushion and enables smooth movements of the joint.
Total Knee Replacement (TKR)
Total knee replacement, also called total knee arthroplasty, is a surgical procedure in which the worn out or damaged surfaces of the knee joint are removed and replaced with artificial parts. The knee is made up of the femur (thigh bone), the tibia (shin bone), and patella (kneecap). The meniscus, the soft cartilage between the femur and tibia, serves as a cushion and helps absorb shock during motion. Arthritis (inflammation of the joints), injury, or other diseases of the joint can damage this protective layer of cartilage, causing extreme pain and difficulty in performing daily activities. Your doctor may recommend surgery if non-surgical treatment options have failed to relieve the symptoms.
Uni Condylar Knee Replacement
Unicompartmental knee replacement is a minimally invasive surgery in which only the damaged compartment of the knee is replaced with an implant. It is also called a partial knee replacement. The knee can be divided into three compartments: patellofemoral, the compartment in front of the knee between the knee cap and thigh bone, medial compartment, on the inside portion of the knee, and lateral compartment which is the area on the outside portion of the knee joint.
Revision Knee Replacement (RKR)
Revision knee replacement surgery involves replacing part or all of your previous knee prosthesis with a new prosthesis. Although total knee replacement surgery is successful, sometimes the procedure can fail due to various reasons and require a second revision surgery.
Revision Hip Replacement (RHR)
Revision hip replacement surgery is performed under general anesthesia. During the procedure, your surgeon will make an incision over the hip to expose the hip joint. Then the femur is dislocated from the acetabulum so that the old plastic liner and the metal socket can be removed from the acetabulum.
Shoulder Joint Replacement
The shoulder is a highly movable body joint that allows various movements of the arm. It is a ball and socket joint, where the head of the humerus (upper arm bone) articulates with the socket of the scapula (shoulder blade) called the glenoid. The two articulating surfaces of the bones are covered with cartilage, which prevents friction between the moving bones. The cartilage is lubricated by synovial fluid. Tendons and ligaments around the shoulder joint provide strength and stability to the joint.
Minimally Invasive Joint Replacement
Total Hip Replacement THR and Total Knee Replacement TKR are very successful surgical treatment for arthritis of the hip and knee respectively.
Over the last several years hip and knee replacement surgery has evolved to a Minimally Invasive technique.
Advantages of Minimally Invasive Joint Replacement are
- Less tissue trauma – muscles and tendons are avoided or separated, not cut
- Faster and less painful rehabilitation
- Smaller incisions and less scarring – two incisions of 1½ to 2 inches each, rather than one 10- to 12-inch incision
- Shorter hospital stay – 1-2 days (vs. 3-5 days); some patients go home in less than 24 hours
- Reduced blood loss and less need for pre-surgery blood donation
- Faster return to work and daily activities
