Brief Summary:

The purpose of this study is to determine if patients undergoing a total knee arthroplasty (TKA) experience a clinically significant reduction in healing time when treated post operatively with a specific form of micro and nano-ampere current. The results of this trial will provide a basis for generalizing its outcomes to apply to other joint replacements and revisions by reducing edema and inflammation and therefore will result in a shorter time to heal.

The study will compare electrically treated and non electrically treated patients by using digitally based measurements to determine objective reductions of lower extremity edema including intra and inter cellular shifts in fluid distribution, increased range of motion (ROM) and muscle strength, and improved functional tests of ambulation.


Condition or disease Intervention/treatment Phase
Osteoarthritis of Knee Edema Wounds and Injuries Device: ODIN1 Other: Standard Care Device: Diagnostic Device Testing Not Applicable

Detailed Description:

This study is intended to assess the efficiency and efficacy of the ODIN1® microcurrent generating device to reduce post-operative edema, shorten the time to heal and regain maximum function in total knee replacement patients. Changes in swelling will be documented by utilizing a 3D scanning device (Perometer) and a Bio-Impedance Spectroscopy (BIS) device (Impedimed SFB7). These instruments quantitate limb volume and inter and intra-cellular fluid respectively with a high degree of accuracy. Measurements will be made from the first post-operative day until the completion of rehabilitation therapy several months later.

Edema volume and fluid distribution data collected from both control and experimental groups will be compared to determine the statistical significance of the difference between these groups. An additional analysis will be performed on data collected from the non-operated lower limb of each patient.

The second primary objective is to determine the time to complete post-op rehabilitation. Completion will be determined by the ability of the patient to experience an optimal outcome by utilizing performance based measurements of knee function including quadriceps strength and range of motion. The time from surgery to optimal post-op rehabilitation will be recorded.

The determinations of statistical significance between the electrically treated and non-electrically treated groups will be made by analysts on a blind basis. They will not know whether a sample data set is from an experimental or control patient. The codes that document which group the set belongs to will be opened after all analysis is completed by an independent analyst.

Arm Intervention/treatment
Experimental: Experimental
This group will receive treatment from the ODIN1 device in conjunction with standard care and diagnostic device testing.
Device: ODIN1

Shortly after surgery, electrodes will be applied to the lower extremity in such a way that the current will flow from the ankle through the knee replacement and pass through the thigh. The frequency of the treatments will vary over the period of time from post-op recovery to end of rehab.

All treatments are applying current that consists of different combinations of intensities within the micro to nano ampere ranges.


Other: Standard Care
Anti-thrombotic medication. Elevation and ice. Pain medications as needed. Dressings changes. Topical antibiotics. Progressive physical therapy.

Device: Diagnostic Device Testing
Diagnostic interventions include: the Perometer which scans the lower extremity and determines its volume to a high degree of accuracy; the Impedimed Bioimpedance Spectroscopy (BIS) device that measures intra and intercellular fluid movement; the Microfet muscle force testing device that provides a digital output of the number of pounds exerted by the quadriceps upon extension; the Acumar digital digital Inclinometer that accurately measures the ROM of the knee; and the K.I.S.S. wound measuring system to measure rate of incision healing.

Active Comparator: Control
This group will receive the standard care and the diagnostic device testing.

Primary Outcome Measures :
  1. Rate of Reduction of post-operative edema [ Time Frame: 120 days ]
    Determine the rate of reduction in edema by measuring the volume changes in the operated lower extremity over time

  2. Decrease in time to heal [ Time Frame: 120 Days ]
    Determine the rate of healing by measuring the time elapsed from surgery to reach optimal function by measuring muscle strength, range of knee motion, standardized rehabilitation testing designed to quantitatively measure ambulation. When these measurements show no signs of improvement for a period of 30 days or greater, then the time elapsed after surgery until the beginning of this 30 day or greater period will be recorded and used as a measure of time to heal.


Secondary Outcome Measures :
  1. Reduction of pain [ Time Frame: 90 days ]
    Record the degree of pain experienced by measuring the pain level on the universal pain scale of 1-10 over time elapsed since surgery.

  2. Reduction of bacterial infections [ Time Frame: 60 Days ]
    Compare the incidence of TKA related infections in all participants. The measurement will be the number of recorded infections, related to the surgery, that has occurred within the first 60 days of that surgery in all participants. That number will be compared between the experimental and the control groups.

  3. Increased healing of the surgical incision [ Time Frame: From the 1st post-op day until 60 Days post-op ]
    Photograph and rate incision healing from 1st post-op day through day 60 comparing all participants.

  4. Reduction of Pain Medication Usage [ Time Frame: 90 days ]
    Record the consumption of all pain medications consumed to mitigate post-operative pain. A total dosage will be calculated in terms of morphine equivalent strengths and compared between the groups.
