TL;DR: High-fired calcium aluminate samples in the form of quarter-inch diameter cylindrical pellets containing interconnecting porous networks were implanted in vivo into canine femurs for 4, 11, and 22-week periods, showing the ceramic samples to be bound lightly by natural bone and gave no detectable signs of tissue incompatibility.

TL;DR: In this investigation, ceramics were studied to determine their role as rigid, abrasive implants in soft, living tissue and the absence of inflammatory cells and the normal morphology and organization of the cells present around all types of implants tested.

TL;DR: The results of this investigation have demonstrated that porous polyethylene is capable of accepting bone growth into pores as small as 40 mum, and the optimum rate of bone ingrowth was observed in pore sizes of approximately 100 to 135 mum, with no increase in the rate ofBone ingrowth observed in samples possessing larger pore size.

TL;DR: The results of this study demonstrate that pyrolytic carbon is a biologically and biomechanically compatible, wear-resistant, and durable material for arthroplasty of the metacarpophalangeal joint.
