A 25-year-old overhead throwing athlete presents with deep shoulder pain and clicking. An MRI arthrogram suggests a Type II SLAP (Superior Labrum Anterior to Posterior) tear, which is confirmed arthroscopically. By definition, what characterizes a Type II SLAP lesion?

Explanation:
SLAP lesions are classified into four main types by Snyder. Type I involves degenerative fraying of the superior labrum but the biceps anchor remains intact. Type II, the most common type requiring surgical repair in active patients, involves the detachment of both the superior labrum and the long head of the biceps tendon origin from the superior glenoid. Type III is a bucket-handle tear of the labrum with an intact biceps anchor. Type IV is a bucket-handle tear of the labrum that extends into the substance of the biceps tendon.
