Here's a couple examples:
Imagine him doing a squat. His right knee will collapse toward the midline causing excessive stress on the lateral knee and medial ankle and hip. This stress if repeated or under enough load could cause injury to his ankle, knee, or hip.
He doesn't have the function to perform a squat with good form so matter how much he tries. He must focus on restoring his function to correct his posture and that will allow him to do any movement with good form.
When doing the lunge with her left leg forward her foot is pointed straight ahead and her knee lines up over her foot to point straight ahead in-line with her hip. This is good form and will protect her knee from injury. Her torso can stay fairly centered over her hips as she creates good torso rotation to the left.
When she attempts to use "good form" with her right leg forward everything falls apart. Her right foot points out at 45 degrees and her knee tries to follow and rotates outward also. Notice how her torso doesn't rotate as far to the right but leans excessively and her left hand drops. This is all caused by an unstable right hip.
