The odd thing about knee errors in the jerk is that they are often not errors in the knees but errors somewhere else. They are symptoms of some other problem.
Often, during the dip, the knees knock in. This can often be corrected by torquing the feet into the ground. The problem isn’t the knees – it is further down at the feet. When the feet don’t torque into the ground, the legs aren’t stable and the knees knock in. This causes a loss in force generation and also puts stress into the knees.
Another mistake that looks like a knee error but is actually a foot placement error is when the knee goes past the ankle in the front foot. This is often because the lifter did not place the front foot far enough forward. The body compensates by driving the knee forward. The trouble with this position is that it isn’t as stable as having the knee stacked over the ankle.
As always, look for the root cause of problems. The knees doing funky things doesn’t necessarily mean that is where the error is.
