Hey I've been dealing with Patellar tendinopathy since July, didn't get serious about it until late August. Saw improvement but regressed recently because I tried to go into plyometrics / sport to early. I've moved back to heavy isometrics twice a day that target quads, hamstring, and soleus calf to strengthen the muscles around the tendon and introduce load without high rate of movement. I've been following Jake Tuuras Jumpers Knee Protocol not sure if you know it, its a 4 stage processes of high weight isos, then lifting, then store and release (plyometrics), and finally return to sport. Thoughts on this program? Going to go back to lifting in a week when the daily pain goes down to 1/10, currently around 3-4/10.
