I just have one disagreement with your statement here. I think the hamstrings are far more important to general knee health than the quads. They are often ignored and a lot of exercises have an insufficient range of motion about the knee to even incorporate the hamstrings to a decent degree.
Since a lot of activities are quad dominant, an imbalance occurs and this could be one thing that leads to unhappy knees.
