I have a lower femur fracture (lower third shaft) of right leg for which it was fixed by a plate screw on 22.7.2016. The fracture is under way of healing and some small gaps are left right now. Major parts were filled with callous. Now I am walking with the help of walker not too much but only for my daily activities. BUT I AM FEELING PROBLEM IN BENDING OF MY KNEE OF AFFECTED LEG. PHYSIOTHERAPY IS GOING ON SINCE 01 MONTHS BUT IT IS BENDING NOT MORE THAN 45 DEGREE AND WHEN PRESSED HARD IT BENDS 50-60 DEGREE. WHAT COULD I DO TO BEND MY KNEE 90 DEGREE. WILL IT PROBLEM IN HEALING PROCESS OF MY LEG OR WALKING. PL SUGGEST. CAN I USER ELBOW CRUTCH IN STEAD OF WALKER AT THIS STAGE.
