Here’s the scenario: twilight, it’s the last run of the day, you are tired and wobbly and as you get off the lift you veer to the right to avoid the two snowboarders fastening their bindings in front of you. Your leg goes one way, your knee the other; you hear an unsettling pop and a sudden sharp pain on the inside of your knee. Congratulations, you just tore your ACL. For skiers, the dreaded ACL injury, the most common ski injury, can mean missing out on an entire ski season and a trip to the hospital, rather than tomorrow’s corduroy.
You may be wondering what the ACL is and why is it such a common ski injury? The Anterior Cruciate Ligament (ACL) is one of the four ligaments of the knee that connect the femur and tibia. The ACL runs diagonally across the middle of the knee and prevents the tibia from sliding out in front of the femur. It also provides the knee with the ability to rotate.
For skiers there are 2 main ways an ACL tear occurs. The first is a sudden stop or acceleration of the leg, resulting in a tear. The other more common cause of a tear is when the leg (or ski) stays in place, while the rest of the body stays in motion. Symptoms of an ACL tear may include a popping sound, swelling of the knee, pain and instability.
ACL injuries happen suddenly and often without warning, but according to Vermont Ski Safety (www.vermontskisafety.com), there are precautions that can be taken to help prevent them. Resorts using the training & techniques offered by Vermont Ski Safety have seen a 50% drop in ACL injuries. Also, according to Ski Magazine, new bindings are now available that can release directly at the heel and are expected to reduce knee injuries.
Tips for on the Slopes:
1. Overall follow the responsibility code and maintain balance and control.
2. When you fall, keep your knees bent with skis parallel and together. Also allow yourself to finish the fall — don’t try to stop sliding with your ski edge.
3. If you jump, know how and where to land – land on BOTH skis and keep knees flexed
4. Use newer ski bindings that were designed to reduce knee injury.
5. Stay hydrated and well nourished – this will increase your awareness on the slopes and help you avoid potentially dangerous situations.
Off the slopes:
1. Strengthen hamstring muscles and muscles around the hips.
2. Keep your equipment in good shape and have bindings checked regularly.
3. Work your upper body – knee injuries often are a result of the upper body becoming tired and letting poles drop behind.
4. Work your core muscles.
5. Cross-train, stay fit and eat a balanced diet.
