The purpose of this study will be to evaluate and compare patients undergoing total knee arthroplasty (TKA) with sensor guidance versus that of a standard technique. Each patient will be assessed for the difference between passive, soft tissue controlled, pressure balance and muscle activated pressure balance.

TKA under standard of care spinal surgery.
Sensor measures and localizes peak load at the medial and lateral tibiofemoral joint interfaces. Loading data is thereby captured intra-operatively through the full range of movement (ROM) using the sensor system.

Knee Society Score (KSS)
The Knee Society Score (KSS) comprises two sections (each worth 100 points) for a maximum 200 points. One section is the Knee Society Clinical Score (KSCS) - points are given for pain, motion, and stability and points are deducted for flexion contracture, extension lag, and misalignment. The other section is the Knee Society Functional Score (KSFS) - points are assigned for walking distances and climbing stairs and points are deducted for use of walking aids. For each section, a score of 80-100 = excellent, 70-79 = good; 60-69 = fair; and \< 60 = poor.
Time frame: Month 12 Post-Surgery
Knee Injury and Osteoarthritis Outcome Score (KOOS)
The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a self-reported outcome measure assessing the patient's opinion about the health, symptoms, and functionality of their knee. It is a 42-item questionnaire, including 5 subscales: symptoms, pain, function in daily living (ADLs), sports/recreation, and quality of life. The maximum score a patient can achieve is 100, indicating no knee problems. The minimum score is zero, indicating severe knee problems.
Time frame: Month 12 Post-Surgery
