No--assuming this is a running and not a cycling technique.
The knee problems are definitely injury related (skiing). He had knee surgery back in the dark ages of the seventies, and one of the chambers of his knee joint now has no cartilage. Orthopedists continue to recommend a total knee replacement, but he's unwilling to go that direction.
This creates some ROM issues and any sort of impact training is out, which is why he picked up cycling in the first place.
Per the posterior chain argument, deadlifts, squats, and the power versions of the oly lifts are on the menu. I am not his cycling coach--I'm operating from ignorance, there--but I will recommend some of the specific drills you folks have illustrated.
Thanks for the help, I'll try to get my facts straight with PWO Endurance nutrition before I present him with my nutritional recommendations. Since most of his training is saddle-time, it makes no sense for me just to give him recommendations for the strength training side.
I remember reading something about Surge being good for soccer players--I'll try to find that article as well.
