📖What is ACL Tear?
An ACL Tear is an injury to the anterior cruciate ligament, one of the key ligaments that stabilizes the knee joint by connecting the thigh bone to the shin bone. This injury commonly occurs during sports that involve sudden stops, changes in direction, jumping, or direct impact to the knee, such as basketball, football, and skiing. Tears can range from partial to complete rupture of the ligament, and a complete tear often causes significant knee instability that interferes with normal activity. The injury is frequently accompanied by an audible pop at the time of injury and rapid swelling of the knee.
