The RS-OA Knee System is a new adjunctive treatment option for the millions of Americans who suffer from pain due to osteoarthritis (OA) of the knee. Unlike traditional treatment options, the RS-OA Knee System addresses the muscle dysfunction and atrophy commonly developed by patients’ OA of the knee.

The RS-OA Knee System allows patients to take treatments in the comfort of their own home with a one hour treatment time and self-adhesive, reusable electrodes. In a single sequential treatment the RS-OA Knee System delivers Interferential Current, Patterned Muscle Stimulation and a unique TENS (TESA¹) modality. Together the different treatment modalities provide superior pain relief, muscle re-education and prevention of atrophy in the upper leg muscles associated with osteoarthritis of the knee.

Interferential current provides pain relief to the upper leg and by decreasing sensitivity allows patients to take a more beneficial Patterned Muscle Stimulation treatment.

Patterned Muscle Stimulation is unique and differs from traditional muscle stimulation that simply contracts and relaxes muscles. Patterned Muscle Stimulation re-educates muscle and prevents disuse atrophy by mimicking the natural gait movement of the leg during high level activity, such as running. This provides for greater stability, reduces pain and improves knee function in a non-traumatic, non-weight bearing treatment option.

The TENS (TESA) modality is delivered directly through the knee joint¹ and is specifically indicated by the FDA for reducing the level of pain associated with OA of the knee. A published clinical study conducted specifically on the use of Interferential Current and Patterned Muscle Stimulation used in the RS-OA Knee System showed decreased pain, increased function and a reduction in stiffness for patients with osteoarthritis of the knee in as little as four weeks².

The RS-OA Knee System is reimbursed by Medicare, Workers Compensation and some Private Insurance companies for patients who have disuse atrophy of their leg muscles.
