Depending on the type of knee problem, different surgical methods and treatments may be performed.
In the case of an arthroscopy ('key hole surgery'), your physician makes a small incision in the skin around the knee. Through this tiny cut, a camera (the arthroscope) is inserted giving the surgeon the possibility to look inside the knee on a screen. An arthroscopy can be used by the surgeon to make a diagnosis but also to perform surgery in connection with the diagnosis. Many sports injuries can be treated arthroscopically.
In some cases the injury requires a more extensive procedure and a larger incision is needed. In this case your surgeon may talk about MIS (minimally invasive surgery) or an open knee surgery. Partial knee arthroplasty, also known as unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) are examples of open knee surgeries.
