The Cold Facts About Knee Injuries
Yes, moguls can cause problems. Bump skiing puts a great demand on the patella (knee cap) and the tendon that connects it to the tibia (leg bone). Just as in basketball, the patella tendon and the smooth surface under the kneecap is cyclicly loaded and can produce microscopic tears in the structures. Such tears can be the forerunners of stress injuries in the unconditioned knee, with pain behind and below the kneecap. Just the position of your body can invite injury. Some bump skiers lean back, putting their weight on the rear of their skis, especially in “”jet” turns. With the newer, higher ski boot and with most bindings, landing on the heel of your ski causes the boot to force the tibia forward. Again, the hamstring muscles cannot react fast enough, and “”pop” goes the knee. Ironically, I’ve found that a good percentage of anterior cruciate ligament tears occur on the flats. And they occur to skiers of all ability levels, including instructors. Typically, the skier cruises onto the flats from the steeper terrain and relaxes. Then he stands up more – extending the knee – and often loses edge control or catches a tip or edge. Again, “”pop” goes the knee.
