okay, so first of all I wouldnt make the knee cap a seperate bone and instead attach it to either leg bone.


The way to fix this issue regardless of what you do is to select the bone above the IK (yellow) bone and go into the "Bone" properties. There under "inverse kinematics" you can find different options on how to limit the way its affected by the IK bone chain.

That way you can tell the bones to only bend on the X axis for example which would stop your leg from bending to the side. Turning of X Y and Z would completely stop the IK from bending it which would be required to make your kneecap stop moving at all. hope this helps
