A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available. The meniscal component includes a mechanism for preventing lift off of the meniscal component from the tibial component, while allowing rotation of the meniscal component relative to the tibial component.

A blade plate, as well as instruments and methods for securing the blade plate to a bone to reduce a bone fracture. The blade plate includes a plate portion and a blade portion extending at an angle relative to the plate portion. The plate portion includes a plurality of holes for receipt of bone screws for securing the blade plate to the bone about the bone fracture. A strut screw, inserted through a hole in the plate portion, spans the angle between the plate and blade portions, and threadingly engages a hole in the blade portion to slightly draw the plate and blade portions together to compress and support the bone fracture. A pair of top screws are inserted through holes in the plate portion at angles with respect to the strut screw on either side of the strut screw. Additionally, the blade plate is designed to closely conform to the surface of the bone to minimize the gap between the bone and the blade plate. In order to secure the blade plate to a bone, a chisel/drill guide, chisel, insertion guide, and screw drill guides are provided.

The invention is directed to an orthopaedic instrumentation assembly 10 located relative to an intramedullary member 12, wherein the intramedullary member is disposed at least partially within a bone. The instrumentation assembly 10 includes an offset bushing 16 having a longitudinal axis and a bore therethrough for receiving the intramedullary member. The bore is disposed non-coaxially relative to the longitudinal axis. A sizing plate 14 has an opening 22 therein, and further includes a portion associated with the opening for receiving the bushing, wherein the bushing is rotatably supported. Upon movement of the bushing 16 or sizing plate 14, the bushing and sizing plate coact to position the sizing plate relative to each of the intramedullary member and the bone.

A provisional implant includes an indicator of implant function. Alternating electrically conductive regions and electrically insulating regions on the surface of the provisional implant cooperate with an electrically conducting mating component to indicate when the mating component is in contact with each of the electrically conducting regions.

A prosthetic ligament includes a braided jacket with an unbraided core which is formed with a portion of the fibers of the braided jacket. This portion is isolated from the remaining braided jacket over a predetermined length of the prosthetic ligament.

A surgical instrument comprising a scalpel handle with a separate protective sheath for use in closed surgical procedures, such as arthroscopy. The protective sheath provides for atraumatic insertion of a scalpel blade into the body and to the actual operative site, minimizing the chance of accidental cutting of surrounding tissue. The handle portion is insertable into the tubular sheath from the distal tubular opening of the sheath. The sheath and handle combination may be engaged relative to each other in a plurality of functional positions.
