 So, you want to address the weird area between your knees and elbows. Not a problem. In real life, the visual point of intersection between two joints moves as they clamp together. And an easy way to simulate that is by placing two correction bones here and here. The idea is when the shin rotates back and forth, this bone will move in this direction and this bone will move in that direction. To accomplish this, in edit mode, click this bone and shift D to duplicate it here. Name it, make sure it is parented to the thigh, then you can duplicate that bone again here. Name that one and make sure that it's parented to the shin. In white paint mode, give the bone greenish yellow control of these points here. Now for the drivers. It looks like the axis that controls rotating in this direction is the red one. Red is the x axis. So the shin's x rotation is going to be the trigger. And what we want to control is the bones up and down motion, which appears to be y location. So that's where we're going to put our driver. So on the first bone under y location, right click, add driver, set object to armature, set bone to shin, type to x rotation, and space to local. And up here type var times negative 0.08. Update dependencies, and right click, copy driver, click the second bone, and under y location, right click, paste driver. Click here and take out the negative to make it positive 0.08, you're done. Now you can see that as we rotate the shin in this direction, this bone moves this way and that bone moves that way. The reason why this one has a negative in the equation is because we want this bone to go up. Like what? The reason why we took the negative out for the second equation is because we wanted it to go down instead. If you want to change the distance that the bones move, you can change this from 0.08 to point something else. And if you want, you can also use this exact same method for the elbow. Hope that helps.
