In today’s scenario knee implant is designed to replace the knee joint damaged bone. The evolution of
knee arthroplasty with improved designs and longer implant life span has taken place in the last 30 years.
Rapid improvements to gain the best possible results are been done. The objective of review is to examine
the materials and manufacturing progress to find the best possible outcomes for future development. In
knee implants, the biocompatible materials like zirconium, Titanium alloys, UHMWP (ultra-high molecular
weight polyethylene), smart materials have developed the performance of the implants. Coated
implants are used for metal sensitive patients. The knee replacement techniques give a relief to the
patient but there are many forces acting on the tibia and femoral components from the daily activities
of a person. These constant forces and infections can lead to slow developed of wear in the joint. Some
of the literatures discuss on knee joint simulation under different constraints and conditions which
can be checked as its real time behavior. Many studies have done simulation analysis to know the behavior
under the different static and dynamic loading conditions. There have been a few studies in field of
knee arthroplasty, but different studies suggest different results. Present article viewed the overall
growth in aspects of materials and coatings with better mechanical and biocompatible properties, manufacturing
processes that will lead to simpler techniques, implant design, analysis of loads for reduction
of wear, finite element analysis to validate the prior information, assessment of failure, sensitivity
detections.
