Second-look arthroscopies were performed at a mean of 13.1 months postoperatively. Clinical outcomes were evaluated according to a visual analog scale (VAS) for pain, American Orthopaedic Foot and Ankle Society (AOFAS) score, and the Tegner activity scale. Statistical analyses were performed to identify various prognostic factors associated with the clinical outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean VAS, AOFAS, and Tegner activity scale scores were all significantly improved from 6.9 \u00b1 0.9 to 3.3 \u00b1 1.4 (VAS), from 67.4 \u00b1 4.9 to 82.6 \u00b1 7.8 (AOFAS), and from 3.0 \u00b1 0.8 to 3.9 \u00b1 0.9 (Tegner; P &lt; .05). Regarding overall patient satisfaction with the operation, 49 (95%) patients reported good to excellent results. Prognostic factors including the patient\u2019s age, sex, body mass index, duration of symptoms, defect size and depth, location of osteochondral lesion of the talus, and the existence of a subchondral cyst did not significantly influence clinical outcomes ( P &gt; .05), except for body mass index on the Tegner activity scale score ( P = .021). Significant differences were observed among clinical outcomes for second-look arthroscopy according to the presence of soft tissue impingement and uncovered areas around the graft ( P &lt; .05). The VAS and AOFAS score at the last follow-up were significantly worse when the articular surface of the tibial plafond at the malleolar osteotomy site was uneven ( P = .031 and .012, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This study showed that the articular surface of the tibial plafond at the malleolar osteotomy site, soft tissue impingement, and uncovered areas around the graft were important factors affecting the clinical outcomes, as observed through second-look arthroscopy. Therefore, surgeons should restore the articular surface accurately after the osteotomy, and more caution should be taken to avoid soft tissue impingement and uncovered areas around the graft when performing osteochondral autograft transfer.<\/jats:p>\n
