An ACL tear refers to a tear or sprain of the anterior cruciate ligament, one of the major ligaments in the knee. It is a common sports injury caused by sudden stops, pivots, or changes in direction, often seen in activities like soccer, basketball, and skiing.

Key Points:

Symptoms: A popping sound at the time of injury, severe pain, swelling, knee instability, and difficulty bearing weight.

Diagnosis: Physical examination, MRI, or X-rays (to rule out fractures).

Treatment: Depends on severity; can include rest, physical therapy, bracing, or surgery (for severe tears).

Recovery: Post-surgery rehabilitation may take 6–9 months or longer for full recovery.

Prevention involves strengthening exercises for the knees and core, proper warm-ups, and maintaining good technique during sports.
