I have been basically off the bike for 7 months now due to patellar tendonosis issues. It has been one of the wrost things I have ever had to deal with. Mentally more than anything because I was so ready to kick ass this season. I am not even sure if I will be able to race next yr at this rate.
I have done everything possible to get it better from Graston/Astym technique, electro therapy, ultrasound, stretching, all through my physical therapist twice a week. Plus everything I do on my own, like muscle building exersises, ice, full stretching routines and very light riding (under 200 watts for under an hour).
Heavy overuse is the dianosis. It is not tendinitis but tendonosis at this point.
Ironic my job is to prevent people from getting these types of issues.
