“Why does my knee bone hurt?”

There is no such thing as a knee bone. Knee is a joint and is formed where 3 bones come together, your thigh bone call the femur, your lower leg bone called the tibia and your knee cap called the patella. There are also a number of other structures such as quadriceps and patellar tendon, a number of ligaments as well as cartilagenous structures. Any of these could be causing pain around the knee. To determine the cause it is better to see an Orthopaedic surgeon for a proper evaluation.

There are several reasons or causes that cause pain in your knee. The most common cause of pain in the knee of the young person knee is sprain or contusion if you twisted your knee. The knee pain can also be because by a tear of the cartilage, i.e., meniscal tear in your knee. If you exercise excessively, you can sustain a stress fracture in your knee. I recommend that you curtail your exercise or activity and to take nonsteroidal anti-inflammatory medication such as Motrin, ibuprofen, Aleve, or Advil. If the pain in your knee does not improve after few days, I will recommend that you see an orthopedic surgeon for X-ray and examination.
I hope that you will feel better soon.

Knee pain can be caused by many things. You should make an appointment to see an orthopedic surgeon. He or she will take a history (that is, ask you questions about your knee pain). Then, he or she will do an examination. After that, it might be wise to do X-rays or even possibly an MRI scan. That is the proper way to proceed with knee pain.
Best of luck.
