Surgical approaches in total knee arthroplasty

Total knee replacement surgery begins with correct planning of both the incision and the exposure of the joint. Indeed, these are factors that are just as crucial to an optimal outcome as choosing the right implant, positioning the components, and balancing the ligaments. While it is true that the standard incision and arthrotomy (with which we are most familiar) will, in most primary implant cases, provide adequate joint exposure, it is also true that cases characterized by certain conditions, such as previous cutaneous incisions, a stiff knee or patella baja, present specific skin and exposure problems that need to be recognized, planned for and overcome.
