RC tendons were sutured to the bone using the double-row technique. EPOP was evaluated 1\u00a0week after surgery using the visual analog scale (VAS).

After 1\u00a0week, VAS pain score was equal to 7.7\u2009\u00b1\u20093.1 and 4.5\u2009\u00b1\u20092.1 in the patients with and without stiffness, respectively (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
