I can't run for crap after my teeneage years doing to much high impact training.
My knees can handle windsurfing, in my opinion, because it keeps me fit keeping the pounds off and our bump and jump conditions are relativley low impact compared to running.
However I recently tried wake boarding and as you are being pulled side on my knees copped a hammering.

Yeah my left knees kinda stuffed already (getting better i think, havn't had trouble for a while). I hurt it the first time doing gymnastics in school PE. Decided to do a back flip from like 1.5m and landed knee first on the floor boards. Thought it was ok after sitting out for like 5 mins so kept going for the day. About 7 hours later i thought **** this hurts and then iced it but the damage was done. Waited 4 days then went to see a physio and yeah eventually it slowly got better. Was on crutches for a few weeks though with a brace. That was so crap.

These are from the 4 days before i went to the physio.



Since i've injured it a few for times playing backyard cricket, playing base ball at school, coming off the motorbike prity hard and windsurfing. Got pictures from every time but i think you can see how it goes most often from the others. The only difference if when i came off the motorbike there were grazes and cuts everywhere, aswell as all over the rest of my body.

Hopefully i'll have no more trouble.

BUBS, please don't EVER post your photos again...I'm traumatized...I'll seek counselling first thing tomorrow...

Have had knee probs for 26 years, the thing that has saved me in last 3 or 4 years is Glucosamine/MSM/Chondroitin = windsurfing the best I ever have in my life (Coz I didn't have to give up, and therefore been able to get to the next level)

That's the actual name of the stuff?? What does it do??

I had major sore Knees, even when just walking. I guess from Windurfing for 28 years, Snow skiing for 30years, snow boarding, motocross racing for many years. I thought i may have to give it all away, because of so much pain! So i went to see a knee Doctor he recommended Good quality fish oil, and Joint support tablets, And also to get back into Push bike riding,Because It is low impact,so much better than Walking.The Bike is great fun addictive, and great when NO wind! It takes a while for it to work but my knees are the best they have been for decades!! and no more pain.and generally i feel fitter and healthier that i ever have.
