What is the most common knee injury?

The most common knee injury is ligament tears, particularly tears of the anterior cruciate ligament (ACL) and the medial collateral ligament (MCL). These injuries frequently occur in sports activities that involve sudden stops, changes in direction, or awkward landings. The ACL is especially prone to injury during pivoting movements, while the MCL can be stressed by direct blows to the outer side of the knee.

In terms of prevalence, ligament tears often lead to significant functional impairment and increased knee instability, making them a frequent concern among athletes and active individuals. The recovery process may involve surgical intervention, particularly for complete tears, and rehabilitation to restore function and strength. Understanding the commonality of ligament tears helps trainers prioritize preventative strategies, such as proper conditioning and technique training, to reduce the risk of such injuries in their clients.
