Pain over the biceps femoris.

Pain with resisted knee flexion.

Joint line pain or diffusion.

Pain over the LCL.

Pain provocation with various stress tests.

Varus instability test to check the LCL. With the patient lying flat and the knee held at about 30° of flexion, the shin is shifted to the medial side. Insufficiency of the LCL will allow the knee to "open up" excessively. The test is repeated with the leg straight. If the knee still opens up excessively, then more than just the LCL is torn.

Joint line tenderness.

Positive McMurray's test. The McMurray's test is performed with the patient lying flat (non-weight bearing) and the examiner bending the knee. A click is felt over the menuscus tear as the knee is brought from full flexion to 90° of flexion.

Pain in the muscle belly.

Referred pain with palpation of trigger point.

Anterior knee pain.

Tenderness in the lateral patellar set.

Positive patellar compression test. The test is performed by compressing the patella down into the trochlear groove as the patient flexes and extends the knee.

Tenderness of the popliteal tendon.

Positive figure of 4 test.

Positive Garrik's test. The test is performed with the patient supine; the knee is flexed to 90°, the leg internally rotated, and the patient is asked to resist the examiner's attempt to externally rotate the tibia.

Pain provocation with straight legs raised or swamp test.

Pain with palpation over bone.
