Hi, thanks for writing to HCM.
Your pain in the groin & burning in mid thigh is related to Total hip replacement
. And pain in the knee & shin is a different entity, which needs a thorough examination to arrive at a possible diagnosis.
Xrays will not rule out infection in the early stages. Whereas in late stages, it is evident in the form of component loosening and presence of radiolucent lines around the acetabular and femoral component.Radionuclide scintigraphy
of the hip joint along with hip aspiration will aid in diagnosing an infection inside the joint.
IT band injury
is unlikely to be the cause of your knee & shin pain.
Hope this information is helpful. Good day
