Abstract: An implant insertion tool for use during a surgical procedure to implant an acetabular cup component into a surgically-prepared acetabulum of a patient's hip includes a metallic elongated shaft, a removable polymeric grip, and a locking nut to secure the grip to the elongated shaft. Such a modular design allows the implant insertion tool to be dissembled prior to sterilization.

Abstract: An orthopaedic prosthesis system and associated instrumentation is disclosed. The system includes femoral and tibial components configured to be used in a number of different implanted configurations. The instrumentation is configured to facilitate preparation of the bones and selection of the implant configuration. A method of using the system is also disclosed.

Abstract: An orthopaedic knee prosthesis includes a tibial insert and a femoral component configured to articulate on the tibial insert. The tibial insert includes a lateral articular surface and medial articular surface that is asymmetrically shaped relative to the lateral articular surface. The medial articular surface is shaped to reduce anterior translation of a medial condyle of the femoral component, while the lateral articular surface is shaped to allow a lateral condyle of the femoral component to pivot, relative to the medial articular surface, along an arcuate articular path. Additionally, one or both condyles of the femoral component may include a femoral articular surface having a curved femoral surface section defined by a continuously decreasing radius of curvature.

Abstract: An orthopaedic surgical instrument system that includes an orthopaedic surgical instrument adapted to be positioned on a proximal end of a patient's tibia, and a tibial bearing trial assembly, and a tibial evaluation component, and a tibial base trial component configured to be coupled to the orthopaedic surgical instrument. A tibial evaluation component includes a base plate and a generally Y-shaped posterior buttress extending upwardly from a superior surface of the base plate, such that the posterior buttress of the insert component is configured to be received in the opening of the tibial bearing trial assembly to prevent rotation of the tibial bearing trial component relative to the tibial base trial component.

Abstract: An orthopaedic surgical system for use in implanting a total knee prosthesis includes an adjustable tibial trial component that is movable in the anterior/posterior direction and rotatable when installed on the resected surface of a patient's tibia. A method of using such a system is also disclosed.

Abstract: An orthopaedic joint replacement system is shown and described. The system includes a number of prosthetic components configured to be implanted into a patient's knee. The system also includes a number of surgical instruments configured for use in preparing the bones of the patient's knee to receive the implants. A method or technique for using the surgical instruments to prepare the bones is also disclosed.

Abstract: An annular cutting tool and related methods are provided for herein that exhibit improved durability, cutting performance, and/or reduced heat generation for bone graft resections. The annular cutting tool can include an annular body having cutting teeth with a flat, flared distal tip for greater durability. An extended gullet can be disposed between groups of adjacent cutting teeth to improve removal of bone debris away from the cutting teeth more and thus prevent binding during use. The annular cutting body can have a recessed surface portion to reduce the area of direct contact to bone and thus reduce heat generated. The recessed surface portion can also provide an area in which bone debris can accumulate away from the cutting teeth to prevent or reduce binding of the tool during use. The annular cutting body can also include a drill bit for drilling a hole in a resected bone graft.

Abstract: An orthopaedic surgical instrument comprising a stem trial component is disclosed. The stem trial component comprises an outer sleeve and a central rod that couples the stem trial component to a surgical reamer. A method of assembling an orthopaedic surgical instrument is also disclosed.

Abstract: A method of assembling an orthopaedic surgical instrument may include selecting a surgical reamer for use in resecting a portion of a patient's bone. The method may also include aligning an outer sleeve of a stem trial component with a distal end of a shaft of the surgical reamer. The method may also include advancing the outer sleeve into engagement with the distal end of the reamer shaft. The method may also include advancing a central rod of the stem trial component along a passageway defined in the outer sleeve into engagement with the distal end of the reamer shaft. The method may also include threading the central rod into the distal end of the reamer shaft to couple the stem trial component to the surgical reamer for use in resecting the portion of the patient's bone.

Abstract: A surgical instrument system and method of use is disclosed. The system includes a bone fixation pin and a surgical instrument configured for use with the bone fixation pin. The surgical instrument includes a sheath extending over the distal end of an elongated shaft and a locking mechanism operable to permit selectively movement of the elongated shaft along the longitudinal axis relative to the sheath.
