Total knee arthroplasty (TKA) is a successful surgical procedure that provides excellent and durable relief of pain and improvement in functional status for patients with knee osteoarthritis. TKA is a very successful procedure, with survivorship exceeding 90% at 10 years, 80% at 15 years, and 75% at 20 years.

Patients' demographic factors, the grade of deformity and the bone quality, and the brand and design of the prosthesis could influence results. Otherwise, the most important factor which leads to a successful TKA is the proper surgical technique. The aim of this video is to show the surgical technique in posterior stabilized TKA, to help young surgeons to understand the principles of this surgery. In this video we show the steps to perform TKA, including: preoperative imaging study and planning, surgical approach, and finally a comprehensive surgical technique to prepare femur, tibia, and patella to achieve good implant alignment and stability. Moreover we show some intraoperative tricks which help the surgeon to simplify the process of surgery and avoid malposition of the components. Different types of deformities are inserted in this video to show how surgical technique should change consensually both on bone resections and soft tissues release and balance. Graphic illustrations are inserted to better explain the rationale of each step of the surgical technique. We believe TKA can be a successful and easy to perform procedure when the surgeon respects the principles of knee joint biomechanics and understands the mechanism of knee implant.
