Abstract: An arrangement for minimizing the amount of bone initially required to be resected off surfaces of a knee joint prepared using a plurality of user-operable adjustable extension tabs that define a stability gap derived from gap measurements taken in each of extension, mid-flexion and flexion, wherein the stability gap is commensurate with a reference plane derivable from the arrangement wherein a final bone resection with a corresponding bone surface with said reference plane provides for optimum balanced angular movement between the tibia component and the femoral component of the prosthetic knee joint post-surgery.

Abstract: An arrangement for the preparation of the proximal surface of the tibia and/or the proximal surface of the distal end of the femur and the posterior femoral condyle for a tibia component and/or a femoral component of a prosthetic knee joint. The arrangement includes an electronic system arrangement that receives or measures data information to which the electronic system can utilise this information to communicate control of a blade and/or cutting implement to resect the proximal surface of the tibia and/or distal end of the femur and/or the posterior femoral condyle to required reference plane cuts that provide for balanced angular movement between the femoral component and the tibia component of the prosthetic knee joint throughout an arc of motion from extension, mid-flexion and flexion.

Abstract: An arrangement for providing the proximal surface of the distal end of the femur and the posterior femoral condyle of the femur for a femoral component of a prosthetic knee joint, said arrangement including an alignment clamp mountable to the femur such that a vertical arm of the alignment clamp includes user-operable lateral adjustable extension tabs and a horizontal arm of the alignment clamp that includes user-operable height adjustable extension tabs wherein the lateral and height adjustable tabs engage with a front plate and a base plate which define out reference planes and/or an axis that can be used in establishing the alignment for the definitive resection cuts to the distal end of the femur and the posterior femoral condyle of the femur.

Abstract: An arrangement for the preparation of the proximal surface of the tibia for a tibia component of a prosthetic knee joint, wherein the arrangement includes a preparation plate that assists in defining a reference plane. A cutting guide arrangement includes an indicator that provides orientation for a cutting blade or saw to cut the final bone resection of the proximal surface of the tibia the same as the reference plane. There is also a mounting arrangement between the joint liner and the cutting guide arrangement, so that in a first mounting position the indicator of the cutting guide is aligned with the same referenced plane defined by the underside of the joint liner and wherein the mounting arrangement also provides a second mounted position wherein the indicator of the cutting guide is aligned with the same referenced plane orientation of the underside of the joint liner but below the initial resected proximal surface of the tibia where the final resection of bone will take place.

Abstract: An arrangement for the preparation of the proximal surface of the tibia for a tibial component of a prosthetic knee joint including a tibial and femoral stability gap preparation plate having a plurality of user operable height adjustable extension tabs that define a stability gap. A stability gap guide drill plate adapted to act as a guide for a drill bit to drill a series of bore holes into the proximal surface of the tibia to a depth commensurate with the height adjustment of the user operable height adjustable extension tabs and a stability gap router plate adapted to allow a router to complete a final bone resection on the surface of the tibia to rout or cut away bone about each of the series of bore holes so as to provide a stable balanced complete angular movement between a tibial component and a femoral component of the prosthetic knee joint throughout an arc of motion from extension, mid-flexion and flexion.
