A structured questionnaire collecting demographic data, postoperative follow-up time, pre- and postoperative range of motion (ROM), American Shoulder and Elbow Surgeons (ASES) and Constant functional scores as well as scapular notching according to the Sirveaux Classification and RSA angle were evaluated by independent observers. The association between functional outcomes and RSA angle was analyzed using a curve estimation approach.\nResults: Seventy-four patients with a mean age of 69.4 \u00b1 8 years and mean follow-up period of 38.2 \u00b1 10.8 months were included the study. The medialized inlay component was implanted in 35 patients, and the lateralized onlay component was used in 39 patients. The mean preoperative ASES and Constant scores improved from 28.4 \u00b1 5.1 and 31.1 \u00b1 5.9 to 73.4 \u00b1 23.3 and 70.5 \u00b1 16, respectively, at the last follow-up (both P &lt; 0.001). The mean pre- and postoperative RSA angles were measured to be 21.3 \u00b1 9.3\u00b0 and 5.5 \u00b1 10.1\u00b0, respectively, on X-ray. The postoperative RSA angle was 10.4 \u00b1 10.3\u00b0 in computerized tomography (CT) scans. There was an excellent correlation between X-ray and CT measurements (rs: 0.971, P &lt; 0.001). It was found that patients with good postoperative functional scores tended to have an RSA angle of 0-10\u00b0 postoperatively. The delta internal rotation of the medialized design group was greater than that of the lateralized design group (P = 0.029).\nConclusion: In patients undergoing RSA for CTA, satisfactory clinical outcomes can be obtained by achieving a postoperative RSA angle of 0-10\u00b0 with an asymmetrical inferior reaming technique.\nLevel of Evidence: Level III, Therapeutic Study\nCite this article as: U\u00e7an V, Pulatkan A, Sar\u0131ka\u015f M, Kap\u0131c\u0131o\u011flu M, Bilsel K.
