Abstract: The gross biocompatibility of the materials implanted was generally satisfactory. Weight gain during implantation due to net sorption of fluid was negligible for PPO and UHMWPE. Delrin AF specimens gained less than 0.5%, while SP-1 and SP-21 gained up to 2% in weight. Amoco-AI specimens gained up to 7% in weight. The friction coefficient of implanted samples of UHMWPE was lower by 20 to 40% than for the virgin material. The friction coefficient of the other implanted materials was usually somewhat higher than …
