Hello, I have gone through your query. After fracture bone needs time to heal and back to normal condition. Calcium supplements and protein supplements like milk and egg should be taken regularly to promote healing. As bone is weak, your joint has pay for it. Muscle forces change and extra load comes to your joint. So till the healing process continue that cut sound will come. No need to worry about this. Follow medications and do particular exercise to avoid same sound even after healing the bone. See a Physiotherapist. This might help you.
