Staff infection following a hip replacement surgery is a huge concern for the surgeon. It happens not infrequently-hence Jack Snow. I've had two hip replacements and each time the "team" will follow up immediately to inspect the incision marks to determine the possibility of a staff infection. And they will keep at it including after one's release from the hospital. I've never heard about staff infections from a turf burn. My understanding of the value of artificial turf is limited but, in addition to the above, one is that the field is consistent as opposed to natural grass which has small valleys and hills that result in an uneven surface. And of course this raises the issue of knee sprains, tears, etc.
