Wounds and Injuries Clinical Trial
Official title:
Accelerated Reduction of Post-operative Edema and Early Return to Function Following Total Knee Arthroplasty (TKA)
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.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Rate of Reduction of post-operative edema | Determine the rate of reduction in edema by measuring the volume changes in the operated lower extremity over time | 120 days | No |
Primary | Decrease in time to heal | 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. | 120 Days | No |
Secondary | Reduction of pain | Record the degree of pain experienced by measuring the pain level on the universal pain scale of 1-10 over time elapsed since surgery. | 90 days | No |
Secondary | Reduction of bacterial infections | 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. | 60 Days | No |
Secondary | Increased healing of the surgical incision | Photograph and rate incision healing from 1st post-op day through day 60 comparing all participants. | From the 1st post-op day until 60 Days post-op | No |
Secondary | Reduction of Pain Medication Usage | 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. | 90 days | No |
