SINGAPORE - Seventeen-year-old Nur Insyirah twisted her right knee playing football when she was just 12. She fell hard and her knee swelled and hurt badly.
Following the incident, Insyirah went for physiotherapy but continued to experience a "funny feeling" in the knee whenever she ran. At times, it also felt like it might give way. She was even able to use her fingers to move her kneecap from side to side.
