Re: Medial pain of distal end of femur located near patellar articulation
There's a lot of stuff going through that area. Not only do you have the medial condyle, you have the articular cartilage, the medial collateral ligaments, synovial membrane and some small nerves and blood vessels that can be damaged. Any and all of those can be bruised and they just take a long time to heal. Depending on how bent the knee was when you landed, you can actually damage the articular cartilage as you expose the joint weight bearing surface.
Have you checked the bulge sign to see if you have any fluid in the joint?
If there isn't any fluid, it is most likely a bad bruise and will take time. If you do have fluid in the knee, then I'd have it checked to see if you tore the medial meniscus...yes, just landing on that knee that way can tear the meniscus...I did it. Tripped over a case of soda in a grocery store and landed on the inside aspect of my right knee and tore the meniscus. Already had the left medial and lateral meniscii removed so I knew what I had done.
So check for joint fluid. If none, give it more time. If it still hurts after about 3 months then see an ortho.
