Risks of total knee replacement include blood clots in the legs that can travel to the lungs (pulmonaryembolism). Pulmonary embolism can cause shortness of breath , chest pain , and even shock .
Complications and Risks of Knee Replacement Surgery. Typical patients find relief of pain, and an ability to increase their activities. However, there are possible complications of surgery, and why knee replacement patients may not be happy. Here are 5 problems that can frustrate patients who have knee replacement.
The best way to avoid any of the possible risks after a total knee replacement is to: Follow all the doctors instructions; Move around and get on your feet as soon as you can; Use the knee but avoid doing too much too fast; Stay active and perform exercises per the doctor; Maintain or reduce your weight
Risks associated with total knee replacement depend in part on the age and overall health of the patient. People with serious heart or lung problems usually are not good candidates for knee replacement surgery. Chronic health conditions (e.g., diabetes) can increase the risk for complications. Complications from knee replacement surgery, such as infection or blood clots, can interfere with recovery.

Unicompartmental knee arthroplasty (UKA) is a surgical procedure used to relieve arthritis in one of the knee compartments in which the damaged parts of the knee are replaced. UKA surgery may reduce post-operative pain and have a shorter recovery period than a total knee replacement procedure, particularly in people over 75 years of age. Moreover, UKAs may require a smaller incision, less tissue damage, and faster recovery times. In the United States, the procedure constitutes approximately 8% of knee arthroplasties. In comparisons with a more extensive surgical procedure called high tibial osteotomy, UKA has equal or better outcomes.
Oxinium is the brand name of a material used for replacement joints manufactured by the reconstructive orthopedic surgery division of medical devices company Smith & Nephew. It consists of a zirconium alloy metal substrate that transitions into a ceramic zirconium oxide outer surface. The ceramic surface is extremely abrasion resistant compared to traditional metal implant materials such as cobalt chromium. It also has a lower coefficient of friction against ultra-high molecular weight polyethylene (UHMWPE), the typical counterface material used in total joint replacements. These two factors likely contribute to the significantly lower UHMWPE wear rates observed in simulator testing. Reducing UHMWPE wear is thought to decrease the risk of implant failure due to osteolysis. All-ceramic materials can have a similar effect on reducing wear, but are brittle and difficult to manufacture. The metal substrate of Oxinium implants makes components easier to manufacture and gives them greater toughness (a combination of strength and ductility). In essence, this technology combines the abrasion resistance and low friction of a ceramic with the workability and toughness of a metal.
Knee replacement, also known as knee arthroplasty, is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve pain and disability. 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 Other major causes of debilitating pain include meniscus tears, cartilage defects, and ligament tears. Debilitating pain from osteoarthritis is much more common in the elderly. 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. The operation typically involves substantial postoperative pain, and includes vigorous physical rehabilitation.
