In one sentence, describe what the following article is about: An ACL injury can be caused by a number of different actions, including landing improperly, twisting your leg, changing direction suddenly or rapidly, or getting hit by someone or something, among others. With an ACL injury, you may experience a range of symptoms. These may include: Pain Swelling within 24 hours Instability of the knee Unable to use your leg's full range of motion Tenderness at your knee joint Difficulty walking The knee joint is comprised of the femur, supporting the thigh or quadriceps muscle, and the tibia and fibula, which are located in the lower leg. There is also cartilage that cushions the knee joint. This cartilage, called the meniscus, is sandwiched between the upper and lower leg bones. Multiple ligaments support the knee and provide stability from all angles, with the ACL playing a critical role. Ligaments join bone to bone. The ACL is formed in a cross-like structure, functioning to join the femur to tibia. This prevents the femur from sliding backward on the tibia. It also prevents the tibia from sliding forward on the femur. The ACL can be strained, torn, or severely damaged. If strained or torn, the ligament is stretched beyond its usual capacity. This results in small or large tears that compromise the integrity of the ligament. Consequently, the knee joint is less stable. In addition, you may suffer a microvascular injury that results in bruising and swelling of the knee. At the other end of the spectrum, in cases of more severe trauma, the ligament may be entirely ruptured, resulting in significant knee instability. This type of injury is also usually accompanied by severe swelling and bruising as a result of the internal damage to blood vessels in the region. ACL tears may occur in conjunction with other ligamentous or meniscal injuries to the knee, or even a fracture of the tibia or fibula. Fractures are more common with "contact" ACL injuries such as a car accident, while "non-contact" injuries occur most commonly in sports like basketball and soccer.
Summary: Recognize an ACL injury. Understand knee joint anatomy. Learn about varying degrees of injury severity. Know that ACL injuries can happen with other injuries.

Do not rinse the fabric, or you may lose some of that beautiful, vibrant color. Just pull the fabric out and gently squeeze the excess dye from it. It might be a good idea to wear plastic gloves for this step. The beet water may stain your hands for a few days. If you don't mind a lighter shade of pink, you can rinse the fabric in cool water. Heat is key to setting the dye into the fabric. If you live in a warm, sunny climate, drying the fabric outside work the best. Otherwise, toss the fabric into the dryer, and dry it on a low-heat setting. If you are drying the fabric outside, keep a pot or bucket under it to catch any drips of dye. Adjust your iron to a no-steam, low-heat setting. Place the fabric on the ironing board, then iron it for about 5 minutes. Not only will this help further set the dye into the fabric, but it will also smooth out wrinkles. Even though your fabric is made from cotton or linen, you should still use a low-heat or warm setting on your iron. Don't use the cotton or linen setting. There is a chance that some of the dye may transfer to the ironing board. Consider covering the board with an old, clean cloth first. Even with the added vinegar, this is a natural dye. It is safer for the environment than regular dye, but it is not permanent. To help preserve the color, hand wash the fabric in cold water only when necessary; avoid using a washing machine, if possible. If you choose to use a washing machine, use a cold water setting. Wash the dyed fabric separately to avoid color transfer.

One-sentence summary -- Remove the fabric from the dye bath and squeeze it. Dry the fabric in the hot sun or in a dryer. Iron the fabric for 5 minutes to further set the dye. Hand wash the fabric in cold water only when necessary.

Q: Adjust the consistency with a little milk if it is too thick.
A: Beat the softened cream cheese and butter with a wooden spoon until they're fluffy. Stir in the Cinnamon Toast Crunch powder until it's mixed well into the cheese and butter mixture. Mix in the vanilla and powdered sugar. Pipe the frosting onto the cooled cupcakes using an offset spatula. Sprinkle a little cinnamon sugar on top of the frosting. Top each cupcake with a Cinnamon Toast Crunch cereal square.

Problem: Article: A humidifier works on both the inside and the outside, allowing your skin to stay hydrated by introducing atmospheric moisture to dry air. Humidifiers help not only with preventing windburn, but also with treating winter conditions such as sore throats and coughs. Humidifiers are generally either warm or cool mist. Choosing between the two is a matter of personal preference, and you may find that different humidifiers better suit different needs. A warm mist humidifier, for example, may be useful while sleeping, while a cold mist humidifier might make more sense at a desk or an office where temperature is controlled but atmospheric moisture is not. Humidifiers can easily be purchased at home goods stores, departments stores, or online. Carry a water bottle around and set reminders for yourself to help you remember to get two to three liters of water per day. Water helps to replenish your body's moisture, and is fundamental in both the prevention of and recovery from windburn. It is recommended that the average adult man get three liters of water a day, and that the average adult woman get 2.2 liters a day. Take a look at weather forecasts before you go out. If the weather is expected to have significant wind gusts or temperatures below freezing, plan to minimize your time outside. If temperatures are projected to get below zero Fahrenheit (-17.7 Celsius), try to avoid going out at all when possible.
Summary:
Use a humidifier. Drink water. Minimize exposure.
