Yes and tendonitis/ inflammation and can get chronic if you don't ease up and start rehab work.
I had tendonitis in my patellar tendon. Tore it tripping in a flight of stairs putting the foot down after a long fall really hard on concrete floor. Pretty damn embarrassing.. I think if It wasn't inflamed it wouldn't tear from that. But maybe...
It's been a year now and I'm back now squatting have progressed up to 270 deep squats for many reps. Eventually I want to go back to 315 but we'll see. I get good stimulation from just 270. I'm pretty happy how well the recovery went but I did alot of rehab, from day one every day for 6 months
I think a lot of times you think if I hadn't done this or that on that day I wouldn't have had a tear but I think also a lot of times something was hanging by a thread and it would have have happened eventually anyway because there was trauma there you were unaware of.
Regarding rehab, I've written about it before, but after I had surgery for my bicep tear, at 12 weeks post-op I met the surgeon and he sort of got mad at me when I said I'm carefully rehabbing with low to moderate weights. He said I should be at max weights by now, "we want you back 100% like you were before. Just don't yank it but load heavy."

I can see his point but on the other hand at some point you may sort of be too strong for your tendons
