There is no need for you to worry about your implant to be removed. By this time your osteotomy
should have been well united. However if you have pain in the operated region of your lower limb, it needs further evaulation clinically and with X-ray. This to assess the bony union. Sometimes if the fracture
or osteotomy is not united it can lead to pain. The other cause of pain would be infection. This can be evaluated with routine blood investigations like Total & Differntial counts, ESR
If the fracture is well united, implant exit can be done. You may need protected weight bearing for about 4 weeks after the procedure.
