Hi, thanks for writing to HCM.
It seems from the description that you have suffered a SOFT TISSUE INJURY
. You could have injured ACL or PCL (ligaments in the knee joint) , a torn muscle, or a Ligament around the knee joint.
To diagnose any of the above injuries, MRI
scan of the knee joint is mandatory.
Till that time , follow the RICE regime along with analgesic
Consult an orthopedic surgeon for further workup and management.
Hope this information is helpful. Good day
