Hi, thanks for writing to HCM.
Any persistent pain at the operated site (a year after surgery) is highly suggestive of INFECTION untill proved otherwise. Simple use of Analgesics or Antibiotics are of no help and can regress symptoms only temporarily.
So, I suggest you to undergo a few hematological investigations & xrays of the local part to diagnose infection.
The only way to eradicate an infection after internal fixation
of bones is to remove the implants and giving a thorough wash followed by appropriate use of antibiotics for a few weeks depending on the sensitivity of the isolated organism.
Hope this information is helpful. Good day
