Radiological results were analyzed by tendon integrity, bone marrow edema, and peri\u2010implant osteolysis. Clinical shoulder function was evaluated with the Constant score.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One\u2010hundred and seventeen patients were enrolled; among them, 63% demonstrated bone marrow edema around the anchors on postoperative 3\u2010month MRI. The edema area percentage was 41%\u2009\u00b1\u20097%. At 6\u00a0months, edema was only seen in 12% of cases, with an area percentage of 18%\u2009\u00b1\u20095%. At 12 and 24\u00a0months, edema was rarely present. Fluid signals around the anchor were observed in 17.6%, 42.7%, 33.3%, and 21.0% of patients at 3, 6, 12, and 24\u00a0months, respectively; the tunnel widening values were 1.1\u2009\u00b1\u20090.4\u00a0mm, 1.8\u2009\u00b1\u20090.5\u00a0mm, 2.3\u2009\u00b1\u20090.6\u00a0mm, and 2.2\u2009\u00b1\u20090.7\u00a0mm at each follow\u2010up, respectively. The sign of osteolysis was significantly more obvious around the lateral anchor than around the medial anchor. The presence of an osseous reaction was not correlated with worse clinical outcome.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Osseous reactions following arthroscopic rotator cuff repair are common and significant even with PEEK anchors. Bone marrow edema does not last more than 6\u00a0months in patients without complications. Peri\u2010implant osteolysis is more evident around the lateral anchor than around the medial anchor and improves gradually over time. The sign of osteolysis is not correlated with clinical shoulder function. Based on these findings, surgeons should be cautious about bone marrow edema lasting more than 6\u00a0months following arthroscopic rotator cuff repair.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>Level
