Progression of asymptomatic degenerative rotator cuff tears - is the 'cable' relevant?

Patterns of tear progression for asymptomatic degenerative rotator cuff tears

These authors studied 139  full-thickness rotator cuff tears with a mean subject age of 63.3 years and follow-up duration of 6.0 years/

Ninety-six (69.1%) of the tears demonstrated integrity of the anterior 3 mm of the supraspinatus tendon (the 'cable').

Fifty (52.1%) of the tears with intact anterior 3 mm of the supraspinatus tendon showed >5mm progression of tear width at a median of 3.2 years from enrollment. 
Twenty nine (67.4%) of tears with disruption of anterior 3 mm of the supraspinatus tendon showed >5mm progression of tear width at a median of 2.2 years from enrollment.

They concluded that the integrity of the anterior 3 mm of the supraspinatus had no effect on the magnitude of enlargement.

Comment: It is not surprising that degenerative cuff tears continue to degenerate. The significance of the 'anterior rotator cuff cable' remains undefined.
