Any Reason Why My Left Knee is Collapsing on the Deadlift?

Hi. I noticed in the video that my left knee collapses inward during my deadlift. I am not sure if this happens all the time, but I think not since I never noticed it before. Admittedly, my left upper glute (piriformis?) has been hurting lately, so maybe that is the problem. Any other thoughts would be appreciated. Thanks.

Inhibited/weak external rotators, tight/overactive internal rotators


I didn’t catch it, or it wasn’t totally obvious.

Could be a rooting issue, could be an ankle/knee stacking issue - in which case flat soled shoes could help. I missed a squat attempt my last meet because my knees caved in, and my coach and I think that the lifting shoes messed up my rooting.
