hi there guys, i came across this doc here in my hospital, he said in a hamstings tendon graft, the patient is going to have pain on knee extension and hence the knee is taken in to extension gradually, what we have to realise here is that, when the grafting is done they would not graft it in such a way that it would prevent complete knee extn,(with in normal limits), instructing the patient not to extend it completely is more of a prophylactic measure to avoid any unwanted circumstances arising thats it,

so i wonder why the knee should not be taken into full extension if the surgeon is confident about his surgery and with regard to hams graft, extn is avoided in the earlier stages probably to splint pain....!
