Subject requires a cemented TKA as a primary indication that meets any of the following condition: (1) Degenerative joint disease, including osteoarthritis (2) Rheumatoid arthritis (3) Avascular necrosis (4) Requires correction of functional deformity (5) Requires treatment of fractures that were unmanageable using other techniques 3. Subject is of legal age to consent and considered skeletally mature (= 18 years of age at the time of surgery) 4. Subject agrees to consent to and to follow the study visit schedule (as defined in the study protocol and informed consent form), by signing the Ethical Committee (EC) or Institutional Review Board (IRB) approved informed consent form. 5. Subject plans to be available through two (2) year postoperative follow-up. 6. Applicable routine radiographic assessment is possible.
Exclusion criteria

Subject requires a TKA on the index joint as a revision for a previously failed surgery, or has the need for complex implants, or any other implant than a standard TKA (e.g., stems, augments, or custom-made devices). 2. Subject has been diagnosed with post-traumatic arthritis. 3. Subject receiving simultaneous bilateral TKA. 4. Subject has one or more of the following arthroplasties that are not fully healed and well-functioning, as determined by the investigator: -Contralateral primary TKA or UKA, however, the subject can only have one knee enrolled in the study. 5. Subject does not understand the language used in the Informed Consent Form. 6. Subject currently enrolled in another orthopedic clinical trial study. 7. Subject does not meet the indication or is contraindicated for TKA according to the specific Smith+Nephew Knee System’s Instructions For Use (IFU). 8. Subject has active infection or sepsis (treated or untreated). 9. Subject is morbidly obese with a body mass index (BMI) greater than 40. 10. Subject is pregnant or breast feeding at the time of surgery. 11. Subject, in the opinion of the Investigator, has advanced osteoarthritis or joint disease at the time of surgery and was better suited for an alternate procedure. 12. Subject has a condition(s) that may interfere with the TKA survival or outcome (i.e., Paget’s or Charcot’s disease, vascular insufficiency, muscular atrophy, uncontrolled diabetes, moderate to severe renal insufficiency or neuromuscular disease, or an active, local infection). 13.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The proportion of subjects achieving post-operative leg alignment 6 weeks after surgery, defined as ± 3° from target as measured by radiographic assessment.;• Component alignment ;• Radiographic assessment (presence of radiolucent lines, osteolysis & implant migration); • 2011 Knee Society Score (2011 KSS) • Oxford Knee Score (OKS) • Forgotten Joint Score (FJS) • Five-level EuroQol five-dimensional (EQ-5D-5L) Visual Analogue Scale (VAS) and index scores | — |
Secondary
| Measure | Time frame |
|---|---|
| • Leg alignment pre- and post-cementation for CORI TKA • System time as extracted from the Subject’s CORI Case Report generated by CORI Software. • Cutting time of the CORI Robotic drills extracted from the Subject’s CORI Case Report, generated by the CORI Software. | — |
