Hellow doc In dec 12nd 2020,my father had this accident where his tibia broke and their were multiple fractures in fibula. So next day he had a surgery where a removable rod was implanted in his broken site. He was able to walk normally 2-3 months ago. Yesterday he was sitting on ground and he got up unmindfully. So he felt a sharp pinching pain where the nails are fixed in his knee area. I'm scared that the nails might have shaken or a bit displaced. What do you think about this ? Should I get a x ray done ? Thankew for your kind suggestions.
