(A) Normal tendon: normal homogenous appearance throughout with no abnormality at the enthesis; (B) abnormal tendon: loss of homogenous appearance and abnormal ragged enthesis±enlarged fluid-filled bursa or partial thickness tear; (C) full thickness tear (0–2.5 cm): lucent patch through the full thickness of the tendon with tear size defined as its width in the sagittal plane; (D) full-thickness tears (>2.5 cm): evidence of large defect or no evidence of tendon tissue present.
