Total Knee / Hip Replacement

Arthroplasty is a surgical procedure to restore the function of severely diseased joints. Restoration of joints can be done by resurfacing or replacing the damaged bone joints. Expert and experienced Orthopedic Surgeons at Department of Orthopaedics at SRV Group of Hospitals carry out both hip and knee arthroplasty on regular basis.  
Knee replacement surgery, also known as knee arthroplasty, involves cutting away damaged bone and cartilage from your thighbone, shinbone and kneecap and replacing it with an artificial joint (prosthesis) made of metal alloys, high-grade plastics and polymers. Metal parts are usually made of cobalt chrome or titanium. Ceramic implants are also available. Selection of the implant depends on patient’s size, weight, gender and age.
Osteoarthritis is one of the main reason people undergo knee replacement surgery. Before knee arthroplasty, an orthopedic surgeon assesses the patient’s knee's range of motion, stability and strength. X-rays help determine the extent of damage. Depending whether damage is there in one or both the knees, the surgeon will perform a unilateral (replacement of one knee) and bilateral (replacement of both the knees) knee arthroplasty. Accordingly, depending on the extent of damage in the knees, any of the four types of arthroplasty can be planned: Total, partial, only knee-cap replacement or revision. 
Arthroplasty is usually done under either general anesthesia, or while you are awake under localized anesthesia. During the surgery, surgical site is shaved and cleaned with antiseptic solution. Patient’s heart rate, blood pressure, breathing, and blood oxygen level are continuously monitored during the surgery. An incision is made in the area of the joint and damaged part of the joints is removed and replaced. During hip replacement, a cut is made along the side of the hip and the muscles connected to the top of the thighbone are moved to expose the hip joint. Next, the ball portion of the joint is removed by cutting the thighbone with a saw. Then an artificial joint is attached to the thighbone using either cement or a special material that allows the remaining bone to attach to the new joint. The surface of the hipbone is then prepared to attach the replace the socket part. The new ball part of the thighbone is then inserted into the hip socket. Incision is closed with stitches or surgical staples and covered with sterile dressing.
About 85% of the hip joint implants last for about 20 years and knee implants up to 30 years. SRV Group of Hospitals has outstanding orthopedic surgeons, anesthesiologists, nurses and rehabilitation therapists who collaborate to achieve the best possible outcomes of care.
