Center for Joint Preservation and Reconstruction

The Center for Joint Preservation and Reconstruction is Lenox Hill Hospital's center for treatment of arthritis and other painful joint problems. The center cares for thousands of patients every year with the most advanced nonsurgical and surgical techniques. Our surgeons have expertise in joint preserving surgeries such as arthroscopy and osteotomy, as well as joint replacement of the hip and knee.
