Brief Summary:
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 in the general population. 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 allow the surgeon and patient to monitor recovery and help ensure critical milestones are being met. Our hypothesis is that this new technology will improve patient outcomes as it pertains to rehabilitation milestones and overall satisfaction as compared to controls who do not utilize this technology.

Arm Intervention/treatment
Experimental: Wearable Technology
Patients in this arm will be provided with their own Consensus TracPatch wearable device as well as instructions on its use.
Device: Consensus TracPatch

Consensus TracPatch will be attached to the participant's shin approximately two inches below the knee through use of an adhesive strip similar to a standard bandage for 6 weeks after total knee arthroplasty.

The information gained by the TracPatch wearable technology will be readily available via a HIPAA secure system to the surgeon and patient in order to monitor post-operative recovery and signal to both parties if any intervention is indicated. The device also monitors for rapid acceleration events which may indicate a traumatic injury. Additionally, the temperature sensor may help detect sub-clinical infection.

No Intervention: Current Standard
Patients in this arm will not be provided with any wearable device.

Primary Outcome Measures :
  1. Range of Motion [ Time Frame: 6 weeks after surgery ]

    Flexion and extension of the knee will be measured with a goniometer in degrees, the sum of which will determine range of motion.

    Measured in degrees, the patients range of motion in the operative knee will be measured before surgery, at the 2-week post operative visit and the 6-week post operative visit.

Secondary Outcome Measures :
  1. Oxford Knee Score [ Time Frame: 6 weeks after surgery ]
    The Oxford Knee Score (OKS) with a total range of 0- 48 with a lower score indicating more severe symptoms. OKS is a 12-item patient reported outcome score designed to assess function and pain after total knee replacement.

  2. Knee Society Score (KSS) [ Time Frame: 6 weeks after surgery ]
    The Knee Society Score is a standardized scoring system developed to rate both the knee prosthesis function and the patient's functional abilities after total knee arthroplasty. The KSS has a total score ranging from 0-100 with 0 indicating more severe symptoms.

  3. Visual Analogue Score [ Time Frame: 6 weeks after surgery ]
    A rating system from 1 - 10 developed to assess the patient's subjective rating of pain. A higher score indicates worse pain.
