I fell onto bent knee. now i get a horrific pain if i kneel, below patella, on the part thats on floor. i basically can't kneel. my walk is okay, there is no fracture and patella is okay. whatshould i do?

You need to : See an orthopedist. How do you know there is no fracture? If you know because you went to a doctor, then what did they tell you? Just because you walk does not mean there is no fracture. Patellar tendonitis can be very painful as well. A proper exam is warranted, particularly with that much pain. I would ice it until being able to be seen.

Dr Sung and another doctor agreed

Many possibilities: A fall directly onto the anterior knee can cause prepatellar bursitis, patellar tendonitis, hematoma, chondral damage to the patella, effusion of the knee, and more. As you can see, the list is long and you should follow up with your orthopedic surgeon to let them know about your ongoing problems. More testing may be needed, then treatment can be rendered.

Dr Ali agreed

Knee pain: Significant pain in the knee after a fall is concerning for a soft tissue injury if the xray shows no fracture. The meniscus (cartilage) could have torn, and that can be seen on MRI scan. Tendonitis can also cause pain below the patella, as can bursitis. Your physician can detect the likely cause, and order the correct test and treatment.

Dr Pappas agreed
