Grip and shoulder strength correlation with validated outcome instruments in patients with rotator cuff tears.

Hypothesis/background: The ability to better define preoperatively the extent of rotator cuff (RC) dysfunction is desired. The study's purpose was to prospectively examine the relationships between absolute and percentage loss (affected compared to unaffected) of grip and shoulder strength, and RC dysfunction.

Methods: Forty-seven consecutive patients with proven RC tears participated in this study.
