In one sentence, describe what the following article is about: The type of brace you end up with will depend on how severe your injury is. If you only have a mild sprain, you may able to get away with a simple compression sleeve. For more serious tears or fractures, you'll probably need a heavier-duty hinged brace reinforced with plastic or metal. Your healthcare provider, usually a doctor or physical therapist, will usually supply you with a brace that's best suited for your injury. There is some degree of trial and error in this process, so if your brace doesn't fit well initially, let them know and they can help you find the right size or style. It will also be important to find a brace in a size that fits you. Sizes are usually displayed on the backside of the packaging, and commercial models may be available in standard sizes. Ask your doctor about getting a second brace so that you can keep your braces clean. When you switch out braces, wash the one you just removed according to the instructions that came with the brace. Start by rolling up your pant leg to get it out of the way. Slip your foot into the top of the brace (the area where it widens to accommodate your thigh) and out through the bottom. Slide the brace up your leg until it rests over your injured knee. If the brace you're using is a wrap style as opposed to a sleeve style, place the inside of the pad against your knee, then wind the straps around. Most braces have a small hole in the front to indicate which way they should go on. When worn correctly, the point of your kneecap should be visible through this hole. This will offer greater comfort and keep the skin beneath the brace ventilated. Align the brace so that the hole doesn't pinch or catch your skin. Make sure the brace won't slide up or down before you secure it. For compression sleeves, you're done once you've got the brace on properly situated. If there are additional straps, guide these around the back of the brace and secure them in front using the Velcro strips. Your brace should be snug, but not too tight. You should be able to fit one or two fingers into the space between the brace and your leg. If you can't, the brace probably needs to be relaxed a bit. Fastening the lower strap first will steady the brace and help you achieve a more stable fit.
Summary: Choose the right style brace. Pull the brace on over your leg. Center the brace on your kneecap. Tighten the straps.

The tongue jack is the front part of the camper that connects to your vehicle. Stack a few 2in 10in (5.1cm 25.4cm) wood scraps under it so it has a place to rest. The wood will ensure that the camper stays level during use. You can also get a wheel dock from a camping supply store. Set the tongue jack in it and you won't need the wood. Once you have made a resting spot for the jack, unhitch it from your vehicle's bumper. Set the jack's metal shaft on the wood. Move your vehicle out of the way so you can finish leveling and stabilizing the camper. Set the level in the camper's door again. This time, lay it so the ends point to the camper's front and back. If one side is lower than the other, you'll need to adjust the camper further. Read your owner's manual to find out how to adjust the jack. Usually the jack will have a crank that you can turn by hand to raise or lower it on its metal shaft. Continue doing this until the camper is level from front to back. Adding or removing wood boards can also help level the camper perfectly. The stabilizing jacks are on the camper's 4 corners. These jacks aren't meant for leveling, but will prevent your camper from rocking and falling out of level. Place 2 or more 2in 4in (5.1cm 10.2cm) wood blocks under each stabilizer to ensure they won't move. If your camper doesn't have stabilizers, you can have a professional permanently install them. Alternatively, place jack stands from automotive stores under the camper's corners. Check your owner's manual to find out how to adjust the stabilizing jacks. Bring the jacks down until they're planted firmly on the wood.
