Complications of total knee arthroplasty

SummaryTotal knee arthroplasty (TKA) is a safe, cost-effective treatment for alleviating pain and restoring function in patients with knee arthritis who do not respond to conservative treatment. It is a commonly performed procedure worldwide with a high rate of patient satisfaction. Despite this, complications may occur and can cause significant morbidity. This paper describes complications occurring in the early and late postoperative period following primary total knee arthroplasty. We highlight potential complications from newer technologies that may become commonplace in the future, such as computer navigation and minimally invasive surgery.
