Normal
Sorry to hear about your guy's accident and that your trip had to end early, hopefully she will get back on the 150 in a week or two after she's healed up and ride again. These knee guards (Thor Force Knee Guards) work well and have pivoting points so you she could walk/sit in them comfortably, plus they have like 6" wide straps so they don't pinch your skin like thin skateboarding/hockey style pads. They can be worn under the pants or over. Either way they are great protection and have saved my knee's countless times.
