Eligibility | Inclusion Criteria: 1. Patient meets the approved indications for use in accordance with product labeling for both the Persona Partial Knee System and the ROSA® Partial Knee System. 2. Body mass index =40 kg/m2 3. Patient is of legal age and skeletally mature 4. Patient is willing and able to provide informed consent. 5. Patient is willing to be randomized into one of two study groups of UKA performed using ROSA® and UKA using Conventional Instrumentation 6. Patient is willing and able to complete scheduled follow-up evaluations as defined in the study protocol. 7. Patient qualifies for primary UKA based on investigator's clinical judgement and has an intact anterior cruciate ligament. 8. Independent of study participation, patient is a candidate for the commercially available Persona Partial Knee System. Exclusion Criteria: 1. Independent of study participation, patient meets any of the contraindications for use in accordance with product labeling of the Persona Partial Knee System and/or the ROSA® Partial Knee System. 2. Orthopaedic procedure or pain management study of any joint within the last or next 6 months; furthermore, bilateral enrollment is excluded in this study. 3. Prior ACL Repair 4. Moderate to severe patello-femoral arthritis, that in the opinion of the investigator, would require patella-femoral arthroplasty. 5. Patient is unwilling to sign the Informed Consent. 6. Would, in the investigator's opinion, be unwilling or unable to comply with the postoperative care instructions or study follow-up schedule. 7. Patient is considered a member of a protected/vulnerable population (Pregnant, prisoner, mentally incompetent, etc.). 8. Patient is institutionalized or is a known drug abuser, a known alcoholic or cannot understand the requirements of study participation. 9.

Primary | Accuracy of implant position | To compare and evaluate the accuracy of implant position of robotic-arm surgical assistant (ROSA® Partial Knee System) with that of conventional instrumentation (Traditional UKA). Accuracy of the Implemented Plan will be evaluated by assessing Implant alignment post-operatively for participants enrolled for both Conventional Instrumentation and the ROSA® Partial Knee System. | 6 Weeks | |
Secondary | Evaluation of Patient safety | Frequency and incidence of adverse events, serious adverse events, adverse device effects, serious adverse device effects, and unanticipated serious adverse device effects as well as device deficiencies. | 24 months | |
Secondary | Evaluation of range of motion | Evaluation of knee flexion/extension pre-operatively and post-operatively | 24 months | |
Secondary | Evaluation of Instability | Medial/Lateral and Anterior/Posterior instability measured from none to severe(>5mm). | 24 months | |
Secondary | Patient Reported Outcome Measure (Oxford Knee Score) | A questionnaire completed by the patient consisting of twelve questions that utilize a 5-point Likert scoring system (0 - 4) resulting in a score ranging from 0 (worst) to 48 (best). | 24 months | |
Secondary | Patient Reported Outcome Measure (KOOS-12) | A questionnaire completed by the patient consisting of a 12-item short form of the original 42-item Knee Injury Osteoarthritis Outcome Score (KOOS), and will be used to measure the patients' perception of pain, function, and knee-related quality of life | 24 months | |
Secondary | Numeric Pain Rating Scale (NPRS) | An 11-point NPRS is a patient self-completed reported outcome and will be used to assess the current level of pain for the affected hip. On this scale, 0 will indicate no pain and 10 will indicate the worst pain imaginable | 24 Months | |
Secondary | Subject Satisfaction | A questionnaire consisting of a single satisfaction question in regard to the subjects knee replacement. Answers will include the following: Very Dissatisfied, Dissatisfied, Neutral, Satisfied, Very Satisfied. | 24 Months |
