Sites will enroll participants into two separate arms for this study (rUKA and Conventional Instrumentation), following the assigned randomization. Consecutive patients who meet all of the inclusion criteria and none of the exclusion criteria will be eligible for participation in the study and will be pre-screened for participation in the informed consent process.~The primary objective of this study is to evaluate and compare the accuracy of the ROSA® Partial Knee System in regards to implant placement with that of traditional instrumentation. This will include the assessment of the planned vs. actual component positioning.~Secondary Objectives include the evaluation of safety and efficacy of this system and will include the assessment of common adverse events, physical exam findings, radiologic results and patient reported outcome measures.~Data collection will occur at the following intervals: Pre-operative, Operative, 6-weeks, 3-months, 1-year, and 2-years. Enrollment for the study is anticipated to last approximately 12-18 months. Allowing for 24 months of follow-up, the total estimated study time to final-patient final-visit will be approximately 42 months.
This is a prospective, multi-center, two-arm, randomized, controlled post-market study to evaluate and compare the clinical accuracy of component placement in robotic-assisted UKA and that of traditional methods.
