Total knee arthroplasty (TKA), also known as total knee replacement, is one of the most commonly performed orthopedic procedures. TKA consists of resection of the diseased articular surfaces of the knee, followed by resurfacing with metal and polyethylene prosthetic components. For the properly selected patient, the procedure results in significant pain relief, as well as improved function and quality of life. In spite of the potential benefits of TKA, TKA is usually performed on an elective basis and should only be considered after exhaustion of appropriate nonsurgical therapies and extensive discussion of the risks, benefits, and alternatives.

Instructions

What happens in a total knee arthroplasty?

The surgeon removes damaged cartilage and bone from the knee. Then the doctor attaches metal implants to the ends of the thigh and calf bones. A plastic spacer goes between the metal pieces and helps the new joint move smoothly.

FAQ

What is the most commonly reported problem after knee replacement surgery?

Pain and Other Physical Complications. Knee replacement surgery can result in physical complications ranging from pain and swelling to implant rejection, infection and bone fractures. Pain may be the most common complication following knee replacement surgery.

What should I not do before knee replacement surgery?

Seven days before surgery: Stop taking all NSAIDs (nonsteroidal anti-inflammatory drugs), such as naproxen (Aleve), ibuprofen (Advil, Motrin) and aspirin. They interfere with blood clotting, which can increase blood loss during surgery.

Is arthroplasty an open surgery?

Arthroscopy and arthroplasty are two minimally invasive surgical types. A traditional or open surgical procedure is one that opens up an area fully. Minimally-invasive procedures encompass both small incision surgeries and those with minimally invasive techniques that do not open up an area fully.
