This document discusses the BioPoly RS Knee System, a partial resurfacing implant made of a patented composite of UHMWPE and hyaluronic acid. A preliminary registry study on the implant shows: 1) Significant improvements in clinical outcomes like KOOS scores over 2 years for 35 patients, compared to historical microfracture outcomes. 2) One revision was needed due to a subchondral bone disorder, with no other structural or technical failures. 3) Over half of patients had previously failed cartilage repair procedures.
