At the end of races, it's common to see the knees of some runners buckle. Is this what they call runner's knee, and is it a serious injury?

    That's called exhaustion. Runner's knee is something else entirely. 

    "Runner’s knee is a broad term used to describe the pain you feel if you have one of several knee problems. You might hear a doctor call it patellofemoral pain syndrome."  It can be a serious injury, depending on what's causing it. It's also not limited to just runners.

    No, it's not runner's knee.

    In a race, it's common to be near collapse at the finish line because the muscles are weakened from build up of metabolic waste. The runner has forced the muscles to keep going, as best as she/he is mentally able. Once across the finish line, the runner is no longer motivated to force the muscles to keep working hard; the desire to let the muscles relax becomes dominant. So, the runner may stagger, wobble, or collapse.

    Runner's knee is an injury to bone, tendon, or ligaments in the knee area, most likely due to overuse / repetitive use.
