Hello,
Thank you for using “Ask a doctor” to post your health query.
I read carefully your question and I understand your concern.
A
fracture would make almost impossible to walk or bare weight on the leg. So if the doctors told you that there is no fracture, then most probably it is not the case.
Knee injuries need more then 2 weeks to get well. You may have blood or fluids inside the knee cap so that is why you cannot bend it, and the cracking that you hear.
To tell for sure if something is torn, would be if you do an
MRI, which will indicate very specifically what is happening in your knee.
But I would say give it some more time to heal, follow the doctors advice, do not overuse it so will allow it to heal.
If not better in 4-6 weeks, or if you feel any instability, then consider seeing the doctor again so they can recommend the MRI or do another physical exam of the knee.
Hope this is helpful.
Let me know if you need more clarifications.
Regards,
Dr. Papaqako
