This study aims to see if outcomes for patients that receive the traditional total knee replacement surgical technique are different than the outcomes for patients that receive robot-assisted total knee replacement. The outcomes we will be tracking include: 1. Patients' self-reported awareness of their artificial joints during activities of daily living; 2. Patient's self-reported pain, other symptoms, function in daily living, function in sport and recreation, and knee-related quality of life; 3. Patients' self-reported general health perceptions, physical functioning, role limitations due to physical and emotional problems, bodily pain, energy-fatigue, social functioning and mental health; 4. The accuracy of implant placement and limb alignment

A robotic-assisted surgical procedure to treat a condition in which the patient's knee joints become diseased or injured due to a loss of cartilage that acts as a protective cushion between the knee joints

Patient Reported Forgotten Joint Score (FJS)
The FJS is a self-completed 12-item questionnaire used to assess patients' awareness of their artificial joint during activities of daily living on an awareness scale of 0 (never) to 4 (mostly)
Time frame: 1 year
Patient Reported Knee Injury and Osteoarthritis Outcome Score (KOOS)
The KOOS is a knee-specific instrument used to evaluate short-term and long-term symptoms and function in subjects with knee injury and osteoarthritis. It consists of 42 questions in 5 subscales; Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and knee-related Quality of Life (QOL).
Time frame: 1 year
Patient Reported Veterans Rand 12-item Health Survey Score (VR-12)
The VR-12 is a 12-item questionnaire corresponding to eight principal physical and mental health domains including general health perceptions, physical functioning, role limitations due to physical and emotional problems, bodily pain, energy-fatigue, social functioning and mental health.
Time frame: 1 year
The Mechanical Alignment of the Post-operative Limb
The mechanical alignment of the entire post-operative limb will be measured at 6 weeks by long-limb radiograph cassettes and compared to the pre-operative plan for accuracy and deviation less than or greater than 3 degrees from the intended target. From each treatment group, the percentage of patients with radiographic outliers (deviation greater that 3 degrees from the expected implant placement) will be compared.
Time frame: 6 weeks postoperatively
