Common causes of knee injuries in athletes include improper training techniques, inadequate warm-ups, and overuse. Sports that require sudden stops, pivots, or jumps place significant stress on the knee joint, increasing injury risk. Additionally, muscle imbalances or weaknesses in surrounding muscle groups can contribute to knee injuries. Lack of proper footwear and uneven playing surfaces also elevate injury chances. Understanding these contributing factors can help athletes take preventive measures and ensure appropriate recovery protocols, allowing for safe participation in their respective sports.
