Have you had tendinitis diagnosed by a Dr?
I have had some pain under my knee caps. I believe that tight/short rectus femoris is a contributing issue to knee pain for me. My MRIs have shown pathology that is a cartilage injury. Does not hurt much to play but I worry about future if not corrected.
Test for tight hip flexors, rectus femoris & iliotibial band -
This video shows how to evaluate the flexibility of muscles in your hip area. These muscles have a lot to do with the posture of your leg and stresses on joints. The video shows how to test the flexibility of the 3 areas of the pelvis- 1) hip flexors (illiopsoas), 2) rectus femoris (also a hip flexor but this one is a two-joint muscle), and 3) iliotibial band. The details of leg angles are important in the videos. (These muscles can create posture problems that cause extra stresses on the knees.)
Read the section under "properties" for age and activity related tightness.
