Superior labrum anterior to posterior (SLAP) lesions may occur in the athletic and working populations and represent a common source of shoulder pain in these patients. With a prevalence of approximately 6% in the general population and even higher in the active, military population, the classi cation, mechanisms of injury, and surgical treatment of these somewhat common injuries have been thoroughly described in the literature. e arthroscopic surgical management of SLAP tears has evolved over the years and varies depending on the type of tear, ranging from simple excision to debridement to formal repair with and without concurrent treatment to the long head of the biceps tendon (tenotomy or tenodesis).
Advancements in imaging, techniques, and instrumentation have improved our ability to perform all-arthroscopic SLAP repairs; yet significant controversy regarding diagnosis, operative indications, and treatment technique continues to exist. To further complicate the matter, substantial anatomic variation has been demonstrated in this region of the shoulder which may sometimes cause a nonpathologic labrum to appear injured, leading to inappropriate or even unnecessary surgery. Clinical outcomes SLAP repair have been reported as good to excellent in 63%–100% of patients; thus, up to approximately one-third of patients are still dissatis ed a er SLAP repair. While recently some authors have analyzed the correlation between presenting symptoms and mechanism of injury, it is unknown if there are any variables or factors that can predict the potential success or failure of SLAP repair for a given patient. e purpose of the present study was to report on potential prognostic factors that may have a significant on clinical outcomes following arthroscopic repair of Type II SLAP tears.
