my wife is 30 years old and is about 40 kgs. Recently she has popping sound from her knee while unbending but having no pain. She has no family history of osteoarthritis. Recently she has started some yoga stretchings for 3 to 4 days a week. Her lifestyle does not include any hard physical work too. What should we do as an early step ?
Welcome to Chat Doctor I have gone through your query and understand your concern. I think she doesn't require any treatment as she is not having any pain. However, she can get her x-rays and vitamin D level.  If these tests shows any abnormalities then she requires treatment. You can discuss with your doctor about it. Hope your query get answered. If you have any clarification then don't hesitate to write to us. I will be happy to help you. Wishing you a good health. Take care.
