Is total knee arthroplasty and replacement the same?

No, total knee arthroplasty (TKA) and knee replacement are not the same. TKA is a surgical procedure in which the damaged or worn-out knee joint is replaced with artificial components. Knee replacement, on the other hand, is a broader term that can refer to various procedures aimed at improving knee function, including TKA, partial knee replacement, knee realignment, and other surgical or non-surgical interventions. TKA is a specific type of knee replacement surgery that involves replacing the entire knee joint, while other knee replacement procedures may only target specific parts of the knee.
