Abstract
A prosthesis for an anterior cruciate ligament features first and second elongate members, first and second separately tensionable cords, a catch means on the bore surface of each elongate member, and a means for securing the elongate members to the femur and tibia, respectively. The prosthesis has the significant advantage of being able to replace and to perform in substantially the same manner as a natural anterior cruciate ligament. The separate tensioning followed by fixing of the two cords in the implanted prosthesis results in a substantially smoother and more stable range of motion than has been possible with prior art prostheses.
