Patients were categorized into 2 groups: pseudoparalysis group (P group) and no pseudoparalysis group (NP group). Active range of motion (ROM) of the shoulder, clinical scores (Constant score and visual analog scale [VAS] pain score), and muscle strength were assessed preoperatively and at 2 years postoperatively. In addition, the correlation between preoperative and postoperative clinical data was analyzed through simple linear regression in the P group.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 69 patients who underwent SCR with the keyhole technique using Achilles graft were included in this study. The P and NP groups had 24 cases and 45 cases, respectively. Preoperative ROM (forward elevation [FE] and external rotation [ER]), Constant score, and muscle strength (FE and ER) were significantly lower in the P group than the NP group. At 2\u2010year follow\u2010up, active ROM (FE,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001; ER,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001), Constant score, VAS score, and muscle strength (FE,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001; ER,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001) were improved in the P group. In the P group, pseudoparalysis recovered in 21 of 24 patients (87.5%) at 2 years after surgery. In terms of patient\u2010reported outcomes, the minimal clinically important differences in the Constant score and VAS score were 8.15 and 1.05, respectively, in the P group and 9.47 and 0.92, respectively, in the NP group. Among the 3 cases in which pseudoparalysis recovery failed, 2 were due to graft failure and 1 had delayed recovery. Prolonged preoperative pseudoparalysis and weaker preoperative ER strength were associated with worse clinical outcomes.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>SCR with the mini\u2010open keyhole technique using Achilles allograft shows favorable outcomes for patients with preoperative pseudoparalysis.
