Dual-index holographic contouring

A knee joint simulator designed to evaluate the mechanical and tribological characteristics of total replacement knee joints will be described. Measurements of penetrations of metallic femoral components into the polymeric tibial components by means of dual index holographic contouring will be presented and the findings compared with observations from detailed studies of wear in well-controlled laboratory machines and the limited evidence of in-vivo performance of replacement knee joints. 

Dual index holographic contouring has been used to record the nature and the extent of femoral penetration into worn polymeric tibial components tested on the knee joint simulator. The system is briefly described and results are presented for two different forms of prostheses., ...
