question: Two months ago I felt a pop in front of my knee during an exercise class. Immediately I was unable to straighten my leg or lift it while straightened. A month ago the MRI came back negative but "Patellar tendinosis." (Not tendinitis) With my insurance HMO it's another month before I have an appointment with a specialist. I'm unable to strengthen quad. Feels its beginning to atrophy. I'm do a few PT exercises that work other muscles group but can't do anything with my quad.  Still have pain in patellar tendon.   (I've done a Naprosyn regimen and I ice my knee and rest everyday, I haven't been walking in 2 months).   Any help? or Words of wisdom that will put me at ease while I wait for this appointment? Thanks
