Sprain / Strain, Knee
A strain is an inflammation to the tendons that connect muscles to the bones and is typically caused by overuse, a sudden increase in activity or from a trauma. Tenderness, pain and mild swelling usually occur with a strain. If left untreated the strained tendons can start to pull away from the muscle with slight tearing progressing to tendinitis. The strained muscle area should be rested and allowed to heal. Compressive supports or braces help hold the muscles and tendons in proper position to allow healing to begin and help prevent further tearing. A knee sprain is a complete tearing of a ligament group in the knee as a result of a forceful twist or blow. Pain and swelling are obvious and occur immediately. The knee is held together by four strong, main ligaments which are the Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL), Medial Collateral Ligament (MCL), and the Lateral Collateral Ligament (LCL). Depending on the severity of the tear your doctor may recommend a brace, complete immobilization, or even surgical reconstruction. During the healing process a knee brace is typically necessary and a supportive brace is recommended after healing to help prevent re-injury.
