Knee arthroplasty, more commonly known as knee replacement, is a surgical procedure in which the weight-bearing surfaces of the knee joint are replaced in an effort to relieve pain and disability. A knee replacement procedure can be partial or total and typically entails replacing the damaged or diseased knee joint surfaces with metal or plastic components.There are a number of reasons for which a knee replacement may be performed, most commonly for osteoarthritis. However, knee replacement surgery is also common to relieve the debilitating pain caused by cartilage defects, meniscus tears and ligament tears.
According to the American Academy of Orthopedic Surgeons, the majority of knee replacement surgeries have a positive outcome. Most people return to their daily activities are able to stay active.
However, in situations where the knee replacement system used is defective, the patient may be required to undergo additional surgeries. Often times these revision surgeries are more painful and require a longer recovery period than the original procedure. One such situation may be the DePuy Synthes Attune® Kneed Replacement System, which was the focus of a June 2017 study published in The Journal of Knee Surgery.
