Texture quality has a substantial influence on the wear characteristics of implants because it regulates wear, abrasion and how the implants interact with neighboring biological tissues. An improved surface quality mitigates friction and wear, prolonging the longevity of implanted materials, decreasing the likelihood of particle wear that may cause detrimental immunological reactions. However, moderate roughness typically enhances the ability of the implant to adhere to and integrate with muscles or bone by raising mechanical adherence and biological adhesion. Therefore, meticulous adjustment of surface quality composite-upgrades wear reduction with biocompatibility enhancement, producing reliably secure implants in biological contexts.

Cell adhesion to metals is extremely important for implant quality; it is highly dependent on surface texture. See e.g. BRUNETTI, V. et al. Neurons sense nanoscale roughness with nanometersensitivity. Proceedings of the National Academy of Sciences, v. 107, n. 14, p. 6264-6269, 2010

Hi there, dear Joseph Ozigis Akomodi , and special thanks to Prateek Pathak for this concise answer.

the surface roughness is a matter of so called "engineering element" you can design it to be high or low depending on your objective desire.

devide the effect of roughness into two effects, one being the higher real surface area compared to the apparent surface area.

and the other being the higher number of sharp spots in a rougher surface which will cause higher tension (as the force applied is equal but the contacting area is less)

feel free to contact me if there's any other question you have
