As you are a respected name in the community, thanks for publishing this. What we ultimately need is some real studies on the forces generated and whether cases like yours are a statistical anomaly, or in fact are indicators of a risky movement. There is huge magic to plyometric training done at the right intensity and frequency, but with any movement, there are also costs. As coaches, we need to make sure that we understand our clients and their goals and present to them an accurate cost/benefit picture. For the average mother/father with the goal of being able to keep up with their kids, those re-bounding box jumps have a lot higher cost compared to hobbling around on crutches at the little league soccer game or climbing up the stairs at their office on crutches.

I also implemented the no-rebounding rule at my gym very shortly after seeing your story. If I were training some legitimate games athletes, I may massage that policy for the sake of specificity.
