The use of bone growth stimulators for osteoarthritis of the knee

Osteoarthritis (OA) is the most common type of arthritis found in the United States [1]. The knee joint is the most frequently affected joint with estimates of 37% of adults over 60 years of age having radiographic evidence of knee OA and 12% having symptoms related to knee OA accompanying radiographic findings [2]. The incidence and prevalence of this debilitating disease combined with lack of effectiveness of conservative treatment has led to estimates that over half of the adults in the U.S. diagnosed with knee osteoarthritis will undergo a total knee replacement [3]. These facts provide the basis for a need for innovative and effective treatments.
