KOOS Study

A word about our knee pain data. The KOOS test.

Patients and customers frequently ask us what the KOOS test is and how we collect our data. KOOS is an acronym for Knee Osteoarthritis Outcome Score. It is a reliable and highly validated measure of knee pain and function. We have been collecting data for almost three years. We typically test just prior to use and then at 1,4 and 8 week intervals.

The data displayed on our home page is very good but it is not a randomized, double blind, placebo controlled study. In fact, our data represents incredibly positive outcome seen with uncomplicated arthritis. We excluded patients with large cartilage defects, an acutely torn unrepairable meniscus, unstable knees due to ligament injuries or large leg alignment defects. Although these patients show similar but highly variable results.

Nonetheless the data is real and these patients are extremely pleased with their results. The patients who do well, stunningly well, have mild to moderate osteoarthritis. Furthermore, we have every indication that the disease progression is slowed or stopped. Most become pain-free and go to "maintain mode" and treat 2 times per week or less.

Our success rate is lower with severe knee pathology but a high percentage of patients
do spectacularly well--patients we did not expect to do well--and continue to surprise us every day with their success. One common characteristic these patients share is a disciplined approach to their own care and a willingness to precisely follow our treatment instructions.

Next week we will be sharing some patient outcomes that even we found very surprising. And soon thereafter we will post some select videos allowing patients to tell their stories directly.
