Summary

The purpose of this study is to look at two different referencing systems for total knee replacement surgery. In anterior referencing system, referencing cuts are made from the front surface of the femur. This allows for a more exact cut. The anterior referencing system is more difficult for the surgeon to use. This may increase surgery time. Posterior referencing, on the other hand, references cuts from the back of the femur. The posterior referencing system is quick and easy for the surgeon to use. Posterior referencing may lead to notching of the femur. The risk of notching is very low and may not affect your results. This is a study that has never been done before. Dr. Heekin uses both referencing systems in his practice. He would like to determine which knee referencing system allows for greater knee flexion after surgery. Knee flexion correlates with function and the ability to return to everyday activities. For example, getting up from a chair, going up and down stairs, stooping, and kneeling.
