Hi my dad's knee part was fractured in three places after active bike fell on the knee portion. Previously my dad had cardiac problem in 2016 and two stents were placed, due to this orthopedic doctor saw the fracture in CT scan and after consulting with cardiac doctor they have stopped the regular tablets like ecosprin, clopidol, tonact, lasilactone. These tablets were stopped to thickness the blood during surgery to stop from flow of more blood.
