Hip degeneration and lumbar spine neuropathy have not been ruled in or out at this point. Iliotibial band friction syndrome and iliopsoas strain are both considerations. However, there is no pain radiation to the anterior thigh ruling out iliopsoas compression of pelvic nerves. Injury to the medial meniscus, medial collateral ligament and patella have been ruled out. There is a sartorius strain. No evidence of a semimembranosus strain.

Question: What advanced diagnostic tests would you order if any at this point?
