The pain could be due to Injury to the muscles in the front part of the thigh called quadriceps muscles or injury inside the knee. One would have to examine you clinically to find out the exact site. Some anti-infflamatory medications will help ease the pain along will limitation of movement for some time. I would suggest that you see an orthopedic surgeon for proper management.
