BioPoly® was established to provide a treatment option for painful cartilage lesions between the extremes of biological solutions and total joint replacement. Utilizing a patented material that is self-lubricating for improved wear properties (via a biological enhancement with Hyaluronic Acid) the BioPoly® RS devices are uniquely designed to replace only the damaged cartilage. Therefore, patients can quickly recover and return to pain-free, active lifestyles.
