Grade 1 contusions will feel tightness in the thigh, the patient may walk with a limp. There is unlikely to be much swelling. Trying to straighten the knee against resistance probably won't produce much pain and the patient will still have nearly a full range of motion when stretching the muscle.
Grade 2 the patient is unlikely to be able to walk properly. There will be occasional sudden twinges of pain during activity, possible swelling and straightening the leg against resistance reproduces pain. Pressing in over the site of injury will be painful and the patient will be unable to fully bend the knee.
Grade 3 contusions mean the patient will be unable to walk with the aid of crutches. They will be in severe pain and significant swelling will appear immediately. Contracting the muscle may produce a visible bulge or gap in the muscle. Expect to be out of competition for 3 to twelve weeks.
