A set of distal femoral knee prostheses which are designed to be more narrow in medial/lateral dimensions with increasing anterior/posterior size than existing prostheses to more closely correspond to the physical anatomy of female patients. The prostheses are designed to have a substantially trapezoidal shape or profile when viewed distally which features a more pronounced narrowing of the medial/lateral dimensions beginning at the posterior end of the prostheses and progressing anteriorly to the anterior end of the prostheses. Additionally, the prostheses each include a reduced profile patellar sulcus and reduced profile anterior condyles to more closely conform to the anatomy of a resected femur, and also include sulcus tracking optimized to conform to female anatomy.

Distal femoral knee prostheses

A method and system for monitoring impaction of a femoral component of a hip prosthesis into a femur in which impaction data generated during the impaction of the femoral component into the femur is received from at least one measurement transducer attached to the femoral component and is normalized by a data acquisition and analysis device. An impaction monitoring metric is calculated based on the normalized impaction data, and femoral component fit and stability data is then generated and output to a user interface based on the impaction monitoring metric.

System and method for preventing intraoperative fracture in cementless hip arthroplasty

Prosthetic hip stems and acetabular cups for use in prosthetic hip joints. The hip stem may include a core having a stem portion and a neck portion, a polymer matrix layer substantially covering the stem portion of the core, and a porous metal layer substantially covering the polymer matrix layer. The polymer matrix layer connects the core and the porous metal layer and provides a stiffness for the hip stem which more closely mimics the stiffness of bone than do known hip stems. The hip stems and acetabular cups additionally include a number of improvements adapted for more optimized results with certain types of patient anatomy, such as the anatomy of female patients, for example.
