Dear Sir, I met a road accident by bike at 13-Dec-2011. Then my Pattella(knee cap broken into 3 pcs), tibia and Femure has broken. after that illizarove treatment done & bones are healed femure n tibia but broken pattella has left without any surgery. As a result broken knee cap(broken into 3 pcs) big piece in position as per my dr. but other 2 pcs are nearby n saperated from main pattella. I m able to straightly raise my leg and walk but problem is that, i can not bend my leg. So it s bending up to 10-15 degree. While walking i m putting my injured leg(right) in straight position because if it is little bit bend position then i feel strengthless. However, i want to bend my leg. Is it possible or not? If possible then what to do? Pls advice. My x-ray photos are attached herewith. Best Regards Sharif
