If you're serious about your dancing, you should also be serious about taking
precautions against injuries. A little common sense and prevention can go a long
way. In dancing, and other sports, the knee takes a lot of abuse. The most
frequently injured ligament of the knee is the anterior cruciate ligament (ACL)
. Ligament tears are among the most serious type of knee injury often resulting
in instability of the joint.
The knee is like a hinge joint, which bends and straightens but also allows
small amounts of rotation. Unlike the hip, the knee does not have a deep socket
to hold the bone in place, so most of its stability is provided by the
surrounding ligaments. The ACL’s main job is to prevent the shinbone from
sliding forward. Sudden forceful moves causes the shin to move forward
excessively on the femur (thigh bone) causing the ACL to tear. Quick action on
the hamstring can possibly decrease the strain on the ACL, protecting it from
damage. Muscle fatigue appears to induce deterioration which is one of the
reasons why injuries are more likely to happen when muscles are tired and
overworked. some tears can be treated non-surgically, however surgery is often
your only option.
What can you do to prevent this? Warming up and cooling down is crucial.
Preventive exercises include broad jumps, single leg hopping, and 180 degree
broad jumps.
