Dr Amit Garud, orthopedic doctor in Kalyan shares insights. An ACL tear is an injury to the anterior cruciate ligament (ACL), a key ligament in the knee that stabilizes movement. It often occurs during sports or activities that involve sudden stops, twists, or jumps. Dr. Amit Garud, orthopedic surgeon at Garud Ortho Clinic, Khadakpada, Kalyan, explains, 'ACL injuries can significantly impact mobility, and early diagnosis is crucial for proper recovery.'  Signs & Symptoms: - A loud 'pop' sound at the time of injury.  - Severe pain that makes movement difficult.  - Rapid swelling within hours of the injury.  - Loss of range of motion, making it hard to bend or straighten the knee.  - Feeling of instability, where the knee gives way when bearing weight.  If you experience these symptoms, seeking doctor's advice is very important. Early diagnosis and proper treatment can help prevent long-term complications and restore mobility.
