Cementless total knee arthroplasty (TKA), also known as uncemented or press-fit TKA, is a surgical procedure in which the knee joint is replaced with implants that do not require bone cement for fixation. Instead, these implants are designed to encourage natural bone growth, allowing the bone to grow into the implant and secure it in place. This method aims to achieve a more natural and durable bond between the bone and the implant over time.
