The rising incidence of arthroscopic superior labrum anterior and posterior (SLAP) repairs

Background: Superior labrum anterior-posterior (SLAP) lesions of the shoulder that require surgical repair are relatively uncommon. However, recent observations suggest that there may be a rise in the incidence of SLAP lesion repair. Materials and methods: The Statewide Planning and Research Cooperative Systems (SPARCS) database from the New York State Department of Health was used to acquire data for all outpatient ambulatory surgery procedures that were performed in New York State from 2002 to 2010. The data were reviewed and analyzed to compare the incidence of arthroscopic SLAP lesion repairs relative to other outpatient surgical procedures. Results: Within New York State, from 2002 to 2010, the number of all ambulatory surgical procedures increased 55%, from 1,411,633 to 2,189,991. Correspondingly, the number of ambulatory orthopedic procedures increased 135%, from 118,126 to 278,136. In comparison, the number of arthroscopic SLAP repairs increased 464%, from 765 to 4,313 (P < .0001). This represented a population-based incidence of 4.0/100,000 in 2002 and 22.3/100,000 in 2010. The mean age of patients undergoing arthroscopic SLAP repair in 2002 was 37 +/- 14 years. The mean age in 2010 was 40 +/- 14 years (P < .0001). Conclusions: The data suggest a substantial increase in the number of arthroscopic SLAP repairs that is significantly more rapid than the rising rate of outpatient orthopedic surgical procedures. In addition, there is a significant increase in the age of patients who are being treated with arthroscopic SLAP repairs.
