Total Knee Arthroplasty is becoming an increasingly common operation. An important part of a successful overall patient outcome is regaining functional range of motion after surgery. Wearable devices for fitness have become increasingly common. This study seeks to utilize wearable technology to enhance the post-operative rehabilitation experience by allowing patients and surgeons to monitor patient recovery in real time. The Consensus TracPatch is a wearable device which utilizes an accelerometer, temperature sensor and step count to monitor patient recovery. This tool provides critical, real-time information that may offer a more complete source of data to understand a patient's postoperative clinical and rehabilitation course and guide physician postoperative management. The study hypothesizes that this new technology will improve patient postoperative mobility and patient-physician communication.
