Purpose : This study aims to determine the effectiveness of high physical activity (PA) on shoulder pain, functionalrecovery, and structural outcome in the early healing phase after arthroscopic rotator cuff repair (ARCR).
Methods: Forty-two patients were included in this study according to inclusion criteria. Subjects were classified intohigh PA (HPA) group (n=22) and low PA (LPA) group (n=20) according to the classification criteria. Differencesbetween groups according to the PA level were analyzed by comparing visual analogue scale (VAS), range of motion(ROM), American Shoulder and Elbow Surgeons Shoulder Score (ASES), and isokinetic strength before and 6weeks, 3, and 6 months after surgery. Structural outcome was analyzed by evaluating magnetic resonance imagingperformed 6 months after ARCR.
Results: VAS, ROM, and ASES were significantly higher in the HPA group at 6 weeks and 3 months after ARCRwith a significant interaction effect between time and group (p＜0.05). The isokinetic muscle strength was significantlyhigher in the HPA group at 3 months after surgery with a significant interaction effect on forward flexion and externalrotation strength (p＜0.05). There was no significant difference in extension and internal rotation strength. In thestructural outcome of 6 months after surgery, the retear rate was lower in the HPA group with a significant trend(p＜0.05).
Conclusion: In this study, higher PA levels in the early healing phase after ARCR were found to result in fasterpain relief and restoration of shoulder function. In addition, higher PA level was associated with lower retear ratesin structural outcomes related to tendon healing.
