Inclusion criteria were patients treated for both cyst\u2010related and non\u2010cyst\u2010related RCTs and patients with a moderate\u2010sized tear (1\u20133\u00a0cm) according to the DeOrio and Cofield classification. A total of 39 patients were separated into two groups: Group 1 (<jats:italic>n<\/jats:italic>\u2009=\u200916) patients with cyst\u2010associated RCT, and Group 2 (<jats:italic>n<\/jats:italic>\u2009=\u200923) patients with no cyst. Implant pull\u2010out and migration were evaluated radiologically on standard antero\u2010posterior shoulder radiographs and rotator cuff re\u2010tear was assessed on magnetic resonance images at the final follow\u2010up examination. Group 1 patients were separated into two subgroups according to cyst size (cyst\u2009&lt;\u20095\u00a0mm and cyst\u2009\u2265\u20095\u00a0mm) and subgroup analysis was performed. Clinical assessment was performed using a visual analog scale, the Constant score and Oxford shoulder score.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean follow\u2010up time was 33.7\u2009\u00b1\u200911.7\u00a0months. The mean cyst size was 5.4\u2009\u00b1\u20091.5\u00a0mm. There was no significant difference in re\u2010tear rates between the cystic and non\u2010cystic groups. The mean implant migration distance was 3.0\u2009\u00b1\u20092.2\u00a0mm in patients with a RCT \u2010related cyst and 0.7\u2009\u00b1\u20090.8\u00a0mm in those without a cyst. A statistically significant difference was found between the groups (<jats:italic>p<\/jats:italic>\u2009=\u20090.002). There was no statistically significant difference between the groups in respect of clinical scores. No implant failure was observed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The ATO method performed with a cortical implant in RCTs resulted in satisfactory recovery and clinical outcomes in the short to medium term with low failure rates. While no implant failures were observed, implant migration was associated with cyst presence. Therefore, judicious use is advocated in the choice of transosseous fixation for cyst\u2010related RCTs and patients should be informed of the possibility of implant migration.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
