详细说明
Survival and outcome data on the Gender Solutions Natural Knee Flex System will be done by an analysis of standard scoring system, radiographs and adverse event records.
Survivorship will be evaluated by monitoring the frequency and incidence of adverse events, serious adverse events, adverse device effects, serious adverse device effects, and unanticipated adverse device effects.
Outcomes will be measured by comparing the overall pain and function performances (based on the Knee Society Scoring System), survivorship, subject quality of life and radiographic parameters of study subjects receiving the Gender Solutions Natural Knee Flex System.

- 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;
- Stable, painless arthrodesis in a satisfactory functional position;
- Severe instability secondary to the absence of collateral ligament integrity;
- Patient has rheumatoid arthritis and an ulcer of the skin or a history of recurrent breakdown of the skin because of their risk of postoperative infection is greater;
