Abstract: Methods and apparatus for performing knee arthroplasty, including, but not limited to, bicruciate retaining knee arthroplasty, are described herein. Methods and apparatus for preparing a distal femur for a femoral implant as well as methods and apparatus for preparing a proximal tibia for a tibial implant are described. These methods and apparatus, in at least some embodiments and uses, facilitate decreasing the complexity of knee arthroplasty procedures such as bicruciate retaining procedures, while maintaining, if not improving on, the safety, accuracy and/or effectiveness of such procedures.

Abstract: An improvement in an acetabular cup component of a prosthetic hip implant in which an acetabular shell receives a bearing member within the interior of the acetabular shell and has at least one bone screw hole, the improvement enabling the interoperative selection of implanting the acetabular shell without the employment of a bone screw or with the employment of at least one bone screw for assisting securement of the acetabular shell within the natural bone at the implant site, the improvement including a plug for seating in the bone screw hole to close the bone screw hole, the plug including a fastener arrangement for engaging the acetabular shell to fasten the plug within the bone screw hole, and a sealing arrangement for engaging the acetabular shell essentially to seal the bone screw hole against the migration of debris from the bearing member through the bone screw hole, the fastener arrangement including an operator arrangement for being selectively operated from the interior of the acetabular shell to
