The primary goal of total knee replacement surgery is to relieve pain and restore knee joint function as much as possible. Surgical techniques require a high level of precision. Inappropriate surgical techniques and related complications adversely affect the long-term survival of the prosthesis. For a successful intervention, the surgeon should know enough about the anatomy and biomechanical features of the knee joint; and apply surgical techniques appropriately by adhering to this information. Knee replacement surgery consists of interrelated sequential steps. The previous step must be performed completely so that there is no problem in the next step.
