Overview
Brief Summary
This study is a prospective, open-label, post-market, non-randomized, multi-center clinical evaluation of the Triathlon Total Knee System using the Triathlon PSR Tibial Insert for primary total knee arthroplasty (TKA) in a consecutive series of patients who meet the eligibility criteria. The SF-36 score of subjects receiving the Triathlon Total Knee with the Triathlon PSR insert is expected to be comparable with that of subjects receiving historical Triathlon PS cemented constructs.

Inclusion Criteria

- •Patient is a male or non-pregnant female, skeletally mature, age 18-75 years at time of study device implantation.
- •Patient has a diagnosis of Non-Inflammatory Degenerative Joint Disease (NIDJD).

- •Patient is already participating in the study for a contralateral total knee replacement.
- •Patient has a diagnosis of avascular necrosis or inflammatory arthritis.
- •Patient has an active or suspected latent infection in or about the affected knee joint at time of study device implantation.
- •Patient has any mental or neuromuscular disorder which would create an unacceptable risk of prosthesis instability, prosthesis fixation failure, or complications in postoperative care.

- •Patient is immunologically suppressed or receiving steroids in excess of normal physiological requirements (e.g. \> 30 days).
- •Patient is diagnosed with lumbar radicular pain.

Outcomes
Primary Outcomes
Mean SF-36 Physical Component Score
Time Frame: pre-operative, 6 weeks, 1 year
The SF-36 is a 36-item patient completed questionnaire to measure general health and well-being. It includes physical and mental status component sub scores; each ranging from 0-100. Low values represent a poor health state and high values represent a good health state.
Secondary Outcomes
- Survivorship of Triathlon PSR Insert(1 Year)
- Range of Motion(PreOp, 6 weeks, 1 year)
- EuroQol-5 Dimension (EQ-5D)(PreOp, 6 week, 1 year)
