Cause of Type II SLAP Repair Failure =
PAIN
• Throwing with Recurrent GIRD may
cause a Recurrent SLAP II Retear.
• Symptomatic Subacromial Adhesions.
• Knot Stack Labral Abrasion.
• Unaddressed Concommitant SGHL
Anterior Rotator Interval Pathology.
Rarely if Ever does the Labrum not heal to the
Glenoid !
Why is Recurrent GIRD Evil ?
• It causes Posterior Superior GH
Instability in ABER.
• Result = Recurrent Type II SLAP Lesion.

Reliable Diagnostic Parameters for Rotator
Interval Pathology: Clinical, MRI, & Scope
• Digital Pain in the Upper Bicipital Groove.
• Anterior Superior Shoulder Pain in ABER relieved by Jobe
Relocation Maneuver.
• Increased GH External Rotation and TMA on the Dominant versus
the Non-dominant Shoulder.
• Asymmetric Sulcus Sign on the Dominant versus the Non-dominant
Shoulder ( Neutral and ER).
• A Widened Rotator Interval on Sagittal Oblique Arthrogram MRI
with Bicep Tendon “Drop – Out” from central in the Pulley.
• Arthroscopic visualized Widened Biceps Outlet.
• Hyperemic Biceps, SGHL, and Upper MGHL with Parallel
Adhesions going into the Biceps Outlet.
• Laxity in the Upper MGHL.

Results: Combined Labral Repair & Interval
Closure: 114 Cases
• All Resolved their Preop ABER Pain.
• All Resolved their Increased ER & TMA to
within 5 degrees of the opposite shoulder.
• Complications: 6 Shoulders (5.2%) required
repeat arthroscopy for removal of
symptomatic Subcoracoid Adhesions before
becoming Pain Free.
Conclusions:
• Associated Rotator Interval Pathology can
present in combination with Traumatic Labral
Pathology.
• Failure to address Associated Rotator Interval
Pathology is the primary cause for Persisent
Pain following a Successful Labral Repair.
• Reliable Diagnostic Parameters for Predicting
concomitant Rotator Interval Pathology are
defined and should be evaluated Preop before
developing a Surgical Treatment Plan.
