Hi, thanks for writing to HCM.
Yes, bone can swell out in case of bone tumours but not in your case of trauma. The swelling that you are feeling at the level of the fracture
could be due to CALLUS
(new bone formation) which will remodel itself over a period of time.
Any fractured bone in the lower limbs
will take around 3-4 months to heal so as to allow you full weight bearing on the leg.
For any displaced fracture, the treatment of choice is by open reduction and internal fixation
either by plates & screws or nails. Meniscal tears are usually addressed by Arthroscopy
Hope this information is helpful. Good day
