Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

25 subjects implanted with a Zimmer-Biomet Posterior Cruciate Retaining (PCR) total knee arthroplasty (TKA) and 25 subjects implanted with a Zimmer-Biomet Posterior Stabilizing (PS) TKA will be asked to perform stepping up and deep knee bend activities while under fluoroscopic surveillance (x-ray video). The movements between the two different types of TKAs will be compared.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subjects will have a Zimmer Persona PCR or PS TKA.
* Subjects must be at least six months post-operative.
* Subjects will have KSS greater than 75.
* Participants must be able to perform the required activities - stepping up and a deep knee bend.
* Subjects must be willing to sign the Informed Consent (IC) / HIPAA form to participate in the study.
* Bilateral subjects may be included in the subject population

Exclusion Criteria

* Pregnant, potentially pregnant or lactating females. To satisfy radiation protocol, each female subject will be asked if she is pregnant, or possibly could be pregnant. A pregnant person will not be allowed to participate in the study. To ensure this, a pregnancy test will be administered to any female participants of child bearing age who have not had a hysterectomy.
* Subjects without the required type of knee implant.
* Subjects who are unable to perform stepping up and deep knee bend.
* Subjects who are unwilling to sign Informed Consent/HIPAA documents.
* Subjects who do not speak English and/or French
