  • Patent number: 10828147
    Abstract: A device for ligament reconstruction includes an elongated body and a hook or loop at each end for receiving a ligament reconstruction member such as an allograft or autograft tendon. The ligament reconstruction member is positioned within a hole that is drilled into a bone, or which is provided within a prosthetic joint. A central portion of a ligament reconstruction member is passed through each end of the device. The ends of the ligament reconstruction members are then fastened to the opposing bone forming the joint.

  • Patent number: 10307189
    Abstract: A prosthetic joint is secured to the bones forming the original joint by utilizing strictly mechanical fasteners, for example, a threaded rod engaging a tapped intramedullary canal. Cross locking members may be provided. The need for bone cement is avoided. The prosthetic joint may be used to replace one end of one bone forming the joint, utilizing the naturally occurring end of the other bone. Alternatively, both bone ends may be replaced with prosthetic joint portions. The decision to replace one or both bone ends may be made mid-surgery. The prosthetic joint portions are secured together utilizing ligament reconstruction members made from portions of the patient's tendons or allograft tendons. A bearing forming the interface between the two joint portions is designed to wear in order to protect the remaining components from wear, and to be easily replaced in relatively simple future surgeries.
