INTERVENTIONAL
Conditions
Summary
This is a prospective, randomized controlled trial using the cruciate retaining, MC Persona to comparing the conventional TKA to ROSA assisted TKA. Patients will be randomized to one of three study trial arms. 1. Standard of care medial parapetallar approach (Control) 2. ROSA PSA medial parapetallar approach 3. ROSA PSA medial subvastus approach Participants will be followed for 1 year post surgery with a combination of perioperative parameters, imaging, patient reported outcomes, functional outcomes, blood and tissue sampling for inflammatory information and activity levels.

- Between the ages of 21 and 80 inclusive
- Patients willing and able to comply with follow-up requirements and self-evaluations
- Ability to give informed consent
Exclusion Criteria10

Interventions
This intervention will consist of using the ROSA alongside patient-specific alignment. The knee incision will be the same as the standard of care (medial parapatellar approach).
This intervention will consist of using the ROSA alongside patient-specific alignment. The knee incision will be an alternative, quad-sparring, subvastus approach.
