Short Term Outcomes in Patients Undergoing Aseptic Total Knee Arthroplasty Revision

Total knee arthroplasty (TKA) has been known to be effective for patients with knee osteoarthritis, a condition that impairs the quality of life of patients by causing pain, limits in the range of motion, and deformity in the knee (1). According to the latest worldwide joint registries, revision for total knee arthroplasty is on average 12% over a period of 10 years and dropped due to the use of advanced implant technology, surgical techniques, and measures to prevent infection (2,3). However, the absolute number of TKA revisions have shown a steady increase due to the greater need for primary TKA (4). To perform a successful revision total knee arthroplasty, certain steps must be followed. Each step should be reviewed in detail and along with a pre-operative planning, techniques for the surgical approach and component removal, and the selection of appropriate prosthetic components should be discussed. Possible technical difficulties such as bone loss, ligamentous instability, and management of the extensor mechanism are also important points to be achieved for a successful revision total knee arthroplasty (5).
