Inclusion Criteria:

• - Patient must be 18 years of age or older at the time of surgery.

• - Patient is scheduled for or has undergone primary total knee arthroplasty using a Persona Personalized Knee System with Canary Tibial Extension (PIQ) TKA implant according to the appropriate surgical technique and IFU.

• - Patient must be willing and able to complete the protocol required follow-up.

• - Patient has participated in the study-related informed consent process.

• - Patient has a platform-compatible personal computer located in their dwelling with substantially reliable wireless internet access and a USB port.

Exclusion Criteria:

• - Simultaneous bilateral TKA.

• - Staged bilateral TKA less than 6 months from indexed procedure.

• - Patient is a current alcohol or drug abuser.

• - Patient is known to be pregnant, breastfeeding, or considered a member of a protected class (e.g., prisoner, mentally incompetent, etc.) - Patient has a psychiatric illness or cognitive deficit that will not allow proper informed consent and participation in follow-up program.

• - Patient has previous history of infection in the affected joint and/or a local or systemic infection that may affect the prosthetic joint.

• - Patient with mental or neurologic conditions who are unwilling or incapable of following postoperative care instructions.

• - Patient with Neuropathic Arthropathy.

• - Patient has rheumatoid arthritis accompanied by an ulcer of the skin or a history of recurrent breakdown of the skin.

• - Patient is undergoing procedures or treatments using ionizing radiation.

• - Patient has a known or suspected sensitivity to one or more of the implant materials.

- Patients with known orthopaedic lower extremity, spinal and/or neurologic conditions that could affect gait

The primary endpoint is community walking speed, calculated as a mean, remotely captured over the 7 days prior to the patient's regularly scheduled office visit: specifically, the correlation (Pearson correlation coefficient) of community walking speed with the 4mWT. The secondary endpoints are as follows:

• - Correlation coefficient between community walking speed and the Timed Up and Go (TUG) Test.

• - Completeness of data collection and transmission by the study device.

• - Correlation coefficient between community walking speed and the Oxford Knee Score.

- Correlation coefficient between community walking speed and the Knee Injury and Osteoarthritis Outcome Score Jr (KOOS JR)

Arms

: PIQ Patients

Patient is scheduled for or has undergone primary total knee arthroplasty (TKA) using a Persona Personalized Knee System with Canary Tibial Extension (PIQ) TKA implant according to the appropriate surgical technique and IFU. If you decide to take part in this research study, the general procedures include one follow-up visit where you will be asked to complete two performance-based tests that are used to assess your physical function following Total Knee Arthroplasty ("TKA"). As part of your standard of care, you will receive a Zimmer Persona® Personalized Knee System with Canary canturioTM (CTE) tibial extension. As part of this study, subjects will be asked to perform two performance based tests called the 4 meter walk test and the timed up and go test. Subjects will also be asked to complete a series of patient questionnaires that will assess their post-operative function.

Interventions

Other: - Performance Clinical Outcome Test

Patients will be asked to perform a fast 4-meter walk test (4mWT) and the Timed up and Go (TUG) test in the clinic during their post-operative follow-up visit. Both performance exams will be performed in a controlled environment within the physician's clinic.
