The NexGen LPS-FLex Mobile Bearing Knee received FDA approval for commercial distribution in the US on December 10, 2007. The approval was in accordance with a "condition of approval" to perform a 10-year post approval study to evaluate the longer-term safety and effectiveness of the LPS-Flex Mobile Bearing Knee. The post approval study will consist of patients from the investigational device exemption study arm (Group 1) as well as patients who are eligible for a total knee replacement and have been chosen to receive the LPS-Flex Mobile Knee (Group 2). Group 1 will be followed from 4 years through a total of 10 years from the date of surgery. Group 2 will be followed from pre-op through a total of 5 years from the date of surgery.

Insufficient bone stock on femoral or tibial surfaces
Skeletal immaturity
Neuropathic arthropathy
Osteoporosis or any loss of musculature or neuromuscular disease that compromises the affected limb
A stable, painless arthrodesis in a satisfactory functional position
Severe instability secondary to the absence of collateral integrity
Total knee arthroplasty is contraindicated in patients who have rheumatoid arthritis (RA) and an ulcer of the skin or a history of recurrent breakdown of the skin because their risk of postoperative infection is greater. RA patient using steroids may also have increased risk of infection. Late infections in RA patients have been reported 24+ months postoperative.
Patient is a poor compliance risk, i.e., history of ethanol or drug abuse, or mental handicap that would compromise patient compliance with respect to rehabilitation or follow-up
Patient is not willing or able to give informed consent to participate in the follow-up program
Patient is not willing to return for all scheduled follow-up appointments as defined by this protocol.
