A sprain of the anterior cruciate ligament, or ACL, is a common injury that occurs when the knee is subjected to sudden twisting or pivoting movements. This type of injury is particularly common among athletes who play sports that involve jumping, cutting, and sudden changes of direction, such as basketball, soccer, and football.
When the ACL is sprained, the ligament is stretched or torn, leading to pain, swelling, and instability in the knee. If left untreated, an ACL sprain can lead to long-term damage to the knee joint and increase the risk of developing arthritis.
If you suspect that you have sprained your ACL, it is important to seek prompt medical attention to prevent further damage to the knee joint. With proper treatment and rehabilitation, most people with an ACL sprain are able to return to their normal activities within a few months.
