Ever since I was about 8 years old, after I tripped running up an escalator with the sharp edge digging into my left knee cap, I developed a funny tendon popping in my left knee. Typically I wouldn't mind the popping sound, however, it really prevents me from doing a full front/normal squat.
This affects my form greatly because once my thighs go below parallel I start to feel a tension in the knee tendon. It feels like pressure building up on my knee cap and if I go all the way down without adjusting my left leg (by rotating my left heel outward a bit) the tendon pops real hard. It feels like a tendon is stuck on the right side of my knee cap and is being pulled to my left side, but it won't snap over until I completely squat down.
This isn't painful, but it feels real awkward (so awkward I only let it happen by accident) and is pretty dang loud. So when I squat I tend to bend my back forward and keep my butt up because I'm scared of this nasty pop feeling.
Is this a bad thing? Anyone know why a tendon is getting stuck (if its even that)? Is there a surgery worth getting to fix this?
