My child 16 years old has often dislocated his patella for 5 years. Taking off suddenly will hurt, but it will recover soon. On July 30th last year, she was operated by a doctor in Guangzhou Orthopedic Hospital, and she was able to bend 90 degrees in three months. It's recovering well now. Can squat. Walking is also very stable. A year later this month, I just had a reexamination and pulled out the nail. The thread of the wound was removed today. It's okay to squat. However, we are from Dongguan, and medical insurance is rarely reported. But I'm also happy that health comes first.

It is estimated that you had a reduction operation at about one year old, and you couldn't bend without rehabilitation training. Go to a big hospital for a diagnosis, and it will be fine. Come on!
