### Patient: Doctor, I badly hurt my knee while playing football last evening. It's quite painful and I am not able to put weight on it. What could be the problem and what tests are needed?
### Doctor: Based on your symptoms, you may have injured your knee joint. We will need to conduct a radiographic imaging procedure such as a plain x-ray or magnetic resonance imaging (MRI) to assess the extent of the damage. Depending on the severity of the injury, we may need to apply a splint or recommend physical therapy exercises or other therapeutic procedures. Surgery may not be required and other non-OR therapeutic procedures on the musculoskeletal system may suffice.
