Background: We evaluated the factors that affect pain pattern after arthroscopic rotator cuff repair.
Methods: From June 2009 to October 2010, 210 patients underwent arthroscopic rotator cuff repair operations. Of them, 84 patients were enrolled as subjects of the present study. The evaluation of postoperative pain was conducted by visual analog scale (VAS) scores during postoperative outpatient interviews at 6 weeks, 3 months, 6 months, and 12 months. The factors that were thought to affect postoperative pain were evaluated by dividing into three categories: preoperative, operative, and postoperative.
Results: Pain after arthroscopic rotator cuff repair surgery showed a strictly decreasing pain pattern. In single analysis and multiple regression tests for factors influencing the strictly decreasing pain pattern, initial VAS and pain onset were shown to be statistically significant factors (p = 0.012, 0.012, 0.044 and 0.028, respectively). With regard to the factors influencing lower than average intensity pain pattern for each period, the stiffness of internal rotation at 3 months postoperatively was shown to be a statistically significant factor in single and multiple regression tests (p = 0.017 and p = 0.004, respectively).
Conclusions: High initial VAS scores and the acute onset of pain affected the strictly decreasing postoperative pain pattern. Additionally, stiffness of internal rotation at postoperative 3 months affected the higher than average intensity pain pattern for each period after arthroscopic rotator cuff repair.
