My buddy swore by the fanciest braces money could buy (like, stupid expensive German ones), but his form was always a mess. Ended up needing surgery anyway after his cartilage basically turned to gravel. The physical therapist told him his lifting stance was doing more damage than the weights themselves.
Those German braces cost more than my rent. Hearing his cartilage turned to gravel is actually horrifying. All that money and the form was still wrecking his knees.
