Knee injuries are a fact of life in any sport, but over the past 30-35 years serious knee sprains, usually involving the anterior cruciate ligament (ACL), have become an inherent risk of modern Alpine skiing, with more than 20,000 sustained each year by skiers in the U. S. alone. The ACL, located near the center of the knee, helps to maintain proper alignment of the load-bearing surfaces. Injury to the ACL can result in an unstable knee, which may lead to expensive surgery or a lengthy period of rehabilitation if the injured skier is to resume an active lifestyle.
There are many ways in which knee injuries can occur in skiing, we concentrate on the two most common scenarios, the Phantom Foot and the Boot induced.
- Avoid high risk behavior
- Routinely correct poor skiing technique
- Recognize and Respond quickly and effectively to potentially dangerous situations
- Don't jump unless you know where and how to land
- How often do I have to inspect my Calibrater Arm (Torque Wrench)?
- Routine Visual Inspection:
Visually Check the Calibrater Arm each day before use. If deficiencies are noted, consult the Maintenance and Repair section of the Calibrater Manual. Most routine maintenance and component replacement operations can be performed in shop. When returning the Arm to the factory for biennial calibration inspection or repair, other Calibrater components do not need to be returned to the factory except as required.
Calibration Check: At the beginning, and at least once during the season, the calibration of the ARM should be verified using a dead weight. See Appendix II of the Calibrater Manual. Any weight used should be checked on a state or federally certified scale. Calibration checks should also be made whenever the accuracy of the Calibrater is called into question.
