Dear friend, welcome to HCM!
The MRI shows a blunt injury
to the bone in the lower end of the thigh bone near the articlating(joint) surface of the condyle with some swelling of the marrow.
There is a probable tear of the articulating rings (sort of shock
absorbers) in the knee joints called medial and lateral meniscus
Your ortho surgeon would examine you physically and advise you the course to be taken.
Was that simple? !!
Take care and please keep me informed of your progress.
I hope to have answered your query satisfactorily.
