During a discussion of the study, an attendee said that in her practice she avoids using the type of brace used in the study with a cutout over the knee in younger patients with PF pain, because of data suggesting that bracing compresses the patella and increases the contact area between the patella and the trochlear notch, thereby increasing stress rather than changing the patella position or movement.
