I fell 15 ft to flat 7 months ago. My right knee was in extreme pain afterwards, swelled up like crazy the next day. Was on crutches for a month and finally had an MRI. The results of the MRI were confusing. The radiologist said no injuries and the knee was healthy. How is that possible? They gave me the images and i can see the ACL and PCL. Today my knee clicks and has moderate pain for the past 6 months?
