report on post-operative effectiveness of the Geko™ device in prevention of pain and swelling after arthroscopic anterior cruciate ligament reconstruction and repairs
The purpose of the research is to report on post-operative effectiveness of the Geko™ device in prevention of pain and swelling after arthroscopic anterior cruciate ligament reconstruction and repairs. The primary research procedures are to report on post-operative effectiveness of the Geko™ device in prevention of pain and swelling after arthroscopic anterior cruciate ligament reconstruction and repairs, apply device after surgery, and review Patient charts with PT (physical therapy) information. The study will enroll 46 subjects; ages 13 to 65, scheduled to undergo primary unilateral anterior cruciate ligament reconstruction with either bone patella tendon bone, quadriceps tendon or Achillies allograft, subject is willing and able to comply with study instructions and commit to all follow-up visits for the duration of the study.
a. Rather than directly stimulating the muscle, FirstKind(company who patented the Geko device) identified a suitable location for accessing the common peroneal nerve where it passes superficially near the skin. By accessing this nerve prior to its deep-superficial branch, FirstKind was able to stimulate two separate complexes of muscles, anterior and lateral muscle enjambment. Stimulating the nerve requires less current and is considerably more comfortable than directly stimulating the muscle, to achieve the same degree of muscle contractions. We have uploaded an information sheet from FirstKind with an illustration of which muscles are stimulated.
