Abstract: Methods and apparatus for performing knee arthroplasty, including, but not limited to, bicruciate retaining knee arthroplasty, ore 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: Instruments for use in anterior approach total hip arthroplasty. Instruments according to certain embodiments of the invention connect to a shaping member such as a broach, reamer or osteotome that is used to prepare the intramedullary canal of a desired femur or other bone for total hip arthroplasty. Such an instrument according to such embodiments can be configurable to allow operation on either the left or right leg, and in doing so to provide lateral offset and anterior offset of the instrument handle relative to the shaping member so that the patient's gut, musculature or other bodily portions may be avoided while still providing desired leverage and control over the shaping member to prepare the intramedullary canal.

Abstract: Patient-matched surgical instruments, and methods for making patient-matched surgical instruments, may include patient-matched surgical instruments having an anatomy facing side with several discrete, physically separate anatomy contacting portions configured to match the anatomy of a particular patient. The anatomy contacting portions may be one or more of non-uniform in distribution, non-uniform in shape or non-uniform in surface area.

Abstract: Disclosed are lockable instrument assemblies for quick and easy configuration of surgical instrumentation. The assemblies are operable between a locked and unlocked position, and generally include an aperture having a shaped profile which receives an adjustment member therein. When the assemblies are placed in a locked assembly configuration, the adjustment member is prevented from rotating or translating within the aperture. When the assemblies are placed in an unlocked assembly configuration, the adjustment member is permitted to rotate or translate within the aperture. Also disclosed are methods of using and making lockable instrument assemblies.
