Developed Femoral Head with hip implant expected to be commercialized 2018/2019. They have a knee implant designed and it will be begin testing after their hip implant is available for market. They also have developed a dental implant. Not to mention they have 2nd gen Si3N4, 3D printing, full porous interbody, Si3N4 coating, & Ceramic On Metal Brazing in development.
Hardly a 1 trick pony.
I should add thats its difficult to commercialize products with very limited resources.
