Clinical Trial 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.


Clinical Trial 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. ;
