sorry to hear about your leg mate hope it heals quickly.
i ripped cartlige in my knee i did a high jump and came down hard and 1 foot came out of my binding as i looped my kite, while the other 1 was stuck in getting twisted as i got dragged through the water and to make it worse, my safety relese had came appart so then i was un hooked and couldn't hook it back in just had to let my kite crash

But after a you just been injured awhile you will just be craving to get back on the water, so dont sell your kite i know i was gonna sell my kite and give it all up but im really glad i didnt.
