This study will compare two different surgical methods used in total knee replacement with the Unity Total Knee Replacement System.
The Knee Joint: Surgical Techniques and Strategies
The study will evaluate these two methods based on patients' ability to perform various tasks prior to surgery and at 4 time points during the first 12 months after surgery. This study will be conducted at a single centre. The study has two treatment groups. One group of 50 knees approximately 50 subjects will have a surgical method that uses mechanical alignment alignment based on how the leg and knee joint move to determine the proper position of the knee replacement device.
Subjects will be randomly assigned to one of the two groups. Clinical and functional tests will be conducted pre-operatively and at 6 weeks, 3 months, 6 months and 12 months to determine overall knee function. In addition, a CT scan will be completed pre-operatively and at 6 weeks to assess changes in alignment.

FDA Resources. Arms and Interventions. Patients in this arm will have the Unity Total Knee Replacement System implanted using a surgical technique that utilizes anatomic alignment via ligament balancing with the tibial cut perpendicular to the tibial anatomic axis. Outcome Measures. The test measures the length of time the subject can stand on their operative leg. The test measures the length of distance a subject can walk in 6 minutes at a pace that does not cause them to become short of breath.
Surgical Techniques and Strategies
The test measures the length of time it takes a subject to climb up a stair block and down the other side. The subject is asked to stand on a Wii Fit balance board while the "Deep breathing" exercise in the Yoga section is selected. The subject is asked to kneel on a mat on the floor and then rise to a standing position. The subject is asked to walk on a level treadmill at a comfortable walking speed. The subject is asked to walk from one end to the other on a specialized track topped with fist-sized pebbles. CT scan will be done to assess the following anatomical items: Medial joint line position Overall limb alignment Joint obliquity Rotation.
Power of knee flexion via peak torque of quads measured on a digital myometer.
