Tear to either the medial or lateral meniscus. The meniscus is the shock absorbing cartilage in the center of your knee.
A sudden hit to the outside of the knee area may cause a tear to the meniscus.
Over time the meniscus may deteriorate or soften, increasing the likelihood of injury. In this case, a sudden twist or turn may cause injury.
Reduce activity to promote healing. Ice, as recommended by a medical professional. Certain stretching and strengthening exercises may be beneficial. Wearing a knee support may provide some warm, compression and stability to enhance the healing process. As with any orthopedic injury, please seek a complete evaluation from a medical professional.
