I had a lateral collateral ligament strain... the ligament that is to the OUTSIDE of the kneecap... everytime I rode it felt like my knee was being stabbed... went and spent $200 for a pro fit.. best money I have spent and worth every single dime! There is NO WAY I would have known to make all the changes that he did... but I have not had one single ride with any pain since! I have no idea if it would be this way for everyone, but it was a miracle. truly, for me! Good luck and I hope you have some wonderful, painfree rides soon...
