So.  You’ve just turned 39 years old.  Your wife has just turned 38.  It’s her birthday and she wants to go to a trampoline park.  WHAT COULD GO WRONG?  Nothing…  nothing that is, until you’re about to leave and decide, “hey, one more time for the camera so the kids can see how much fun this was.”





Triple jump, bounce off the wall for the fourth jump, twist around and triple jump back to the starting point?  SO MUCH FUN…  the first few times I did it.

But note how my right leg is more extended than the left?  That apparently was significant.  Because when I landed, even though it was not an awkward landing, my right knee gave out.

Patellar tendon completely came off the patella (knee cap), leaving me with something that only vaguely resembles a knee.



MRI tomorrow, surgery Tuesday, 6-8 weeks of crutches and several months of rehab.  Yuck.

In the meantime, stay tuned for some guest posts Smile

    1. Thank you! Are you the single dot on Moscow in the user group survey? If so, say hi to Snowden for us 🙂

  1. I tore my patella tendon playing rugby a couple of years ago – strangely, it wasn’t that painful at the time. Best of luck, you’ll get through this and come out stronger!

  2. I do hope you get better soon. I suspect your wife won’t bring you to the trampoline park the next time 🙂

  3. And all caught on tape (well, photos.) Reminds me of those “watch this” youtube videos. The ones that don’t end well. Anyway, happy healing!

  4. Kind of ironic that you have a picture of the movie “White Men Can’t Jump” on your page. Sadly here is another data point that supports that conclusion. Get well soon my friend.

  5. Even though the injury and resulting recovery stinks, I was so glad to meet you and your wife and take care of you. I hope the surgery goes well and the recovery is smooth.

    1. Hey thanks Heidi! I still have a short post to write about some of the cool people who helped me out that night 🙂

  6. Rob, Best wishes for a speedy recovery.
    The class week was great, making lots of progress with DAX. 🙂

  7. I had heard that the waivers they make you sign at these places have some pretty scary language. Apparently for good reason 🙂
    Get well soon! Really looking forward to your next book.
