That's a good example why A 35yr old boy shouldnt still ride a skateboard you really get hurt. Zack and I had a early morning session because of the heat when I got home I was packing the Sti for Autox and Zack was alliing over my spare that I had taking out of the trunk it look easy enough so I tried it. I landed it few times and then wham I really do not know what happenned next thing I know my knee is the size of grapefruit and Im in a shit load of pain! So i get in see my Orthapedic(sp) yesterday He says you have a serious problem your knee has been grinding against bone exposing the scews you have in your tibia platue you need a knee replacment so he recomended me to a Dr. in sac to scope the knee to see what is what I will keep you guys in the loop and teel you whats going on.The only thing good aboout this is the parking I will get out of this
