Total knee replacement (Also Known as Total Knee Arthroplasty) is surgery with severe knee damage. A knee replacement can relieve pain and allow you to be more active. Your doctor may recommend this procedure if you have knee pain, but medicine and other treatment are no longer helping.
Advancements in the joint replacement surgery have resulted in performing total joint procedures in the outpatient surgery center for patients who meet specific criteria. Our surgery center began performing total joint surgeries on select patients in 2010. We provide a high quality and safe alternative to having the procedure performed as an inpatient. This option provides significant cost savings to the patient as well as the insurance company while promoting high quality and safe care. Please contact the Ambulatory Surgical Center if you are interested in this option.
THE PROCEDURE: Total or partial knee replacement is performed in an operating room after you are given general anesthesia. Damaged cartilage and bone are removed from the knee joint. Man-made pieces are then placed in the knee. The surgery takes approximately two hours.
After you receive anesthesia, your surgeon will make an 8 to 10 inch cut over your knee. Next, your surgeon will:
• Move your kneecap out of the way, and then cut the ends of your thighbone and shin bone to fit the replacement part.
• Prepare your kneecap for the new pieces that will be attached.
• Fasten the two parts of the prosthesis to your bones. One part will be attached to the end of your thighbone, and the other part will be attached to your shinbone.
• Attach both parts of the underside of your kneecap. A special bone cement is used to attach these parts.
• Repair your muscles and tendons around the new joint and close the surgical cut.
AFTER THE PROCEDURE: After surgery, you will be given pain medication through IV or by mouth as well as an antibiotic to prevent infection. Most people are also given a medication to help prevent blood clots in the legs. Compression sleeves (devices that are worn on the legs and inflate periodically) are often worn to prevent blood clots. A majority of people can stand and walk within a few hours after the surgery.
The results of a total knee replacement are usually excellent. The operation relieves pain for most people, and many do not need help walking after they recover.
The majority of the artificial knee joints last 10 to 15 years while others can last as long as 20 years.
