Hello,
As you had a fall directly over the knee there might be chances for having a ligament inflammation so the swelling and the pain is persisting.
As it is also an acute injury I would advise you to do a hot water fomentation and keep the leg elevated over the pillow while in the sleeping position.
Also, you should wait to see if in 7 days of the time the pain does not come down and the swelling does not come down then you should look for taking an
MRI or an X-ray to see if any kind of
fracture on
ligament injury is present.
If there is a change in the pain and swelling then you can start with static quadriceps and static
hamstring exercises along with the straight leg raise so the weaker muscles will get the strength and you will be able to walk with his without limping the leg.
Also, I would advise you to stabilize the knee with the kneecap as it will avoid much mobility in the knee joint and avoid giving strain or
stress to the internal structures of the knee joint.
In my clinical practice of our 12 years, we always wait to see if there is any small injury or big injury if it's a ligament injury we wait to see for seven days and post that we plan for an X-ray or an MRI and then proceed with treatment accordingly.
Hope I have answered your query. Let me know if I can assist you further.
Take care
