What the trial is, and whether it could suit you
Previous motion analysis studies have demonstrated excellent ability to distinguish subtle differences in gait between normal subjects and those suffering from arthritis. With proper techniques and analysis differences between osteoarthritis patient groups can be distinguished. Previous research has indicated that subjects who received a single-radius design total knee replacement have superior gait performance that those who received a multi-radius design total knee replacement. The DJO Global Empowr PS Knee System is a single-radius lateral pivot design. This design should achieve reproducible more natural knee function and improved patient outcomes and satisfaction. A motion analysis laboratory will be used to collect gait data from patients who are going to receive a Empowr PS knee device and also from age-matched control subjects. These data will be compared with data previously col

3. Subjects with a BMI\>40
4. Subjects who had an active infection or suspected latent infection in or about the joint at the time of surgery.
5. Subjects whose bone stock was compromised by disease, infection or prior implantation which could not provide adequate support and/or fixation of the prosthesis.
6. Subjects who had any mental or neuromuscular disorders which created an unacceptable risk of prosthesis instability, prosthesis fixation failure, or complication in postoperative care.
7. Subjects with severe instability of the knee joint secondary to the absence of collateral ligament integrity and function.
