Why am I not able to bend my knee after aspiration and physiotherapy?

Q: I slipped in the bus and had a knee injury a month ago. Initially, I had a knee aspiration done and then a plaster for two weeks. Even after that there was some accumulation and aspiration was done twice after which the doctor asked me to put a knee-brace for a week. After a week there was some swelling, so he asked me to go for physiotherapy. I am still not be able to bend my knee more than 10%. I have taken all the precautions required and I use a stick while walking. Should I go for MRI?

A:An MRI should be done to rule out any other complication. Hamstrings and quadricep exercises will strengthen muscles around knee and can be done under the guidance of an experienced physiotherapist. Weight bearing exercises will allow you to walk without a stick.
