The purpose of the present study was to prospectively evaluate the 2-year clinical outcomes for patients with medial osteochondral lesions of the talus that were treated with the TOPIC procedure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Forty-three patients were prospectively assessed before and 24 months after the TOPIC procedure. All procedures were performed through a medial distal tibial osteotomy. Clinical assessment preoperatively and at 24 months of follow-up included determination of the Numeric Rating Scale (NRS) scores for pain during walking (primary outcome), at rest, during running, and during stair-climbing. The Foot and Ankle Outcome Score (FAOS) and the Mental Component Summary (MCS) score and Physical Component Summary (PCS) score of the Short Form-36 (SF-36) were also assessed. A computed tomography (CT) scan was performed 12 weeks postoperatively to assess union of the distal tibial osteotomy site and at 1 and 2 years postoperatively to assess consolidation of the graft as well as cyst development in the graft.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>All enrolled patients were available for follow-up. The median NRS score for pain during walking improved from 7 points preoperatively to 2 points at 2 years postoperatively (p &lt; 0.001). All other NRS scores for pain improved significantly. All FAOS subscale scores improved significantly, including those for pain (from 53 to 75), symptoms (from 50 to 61), activities of daily living (from 68 to 88), sports (from 30 to 55), and quality of life (from 19 to 38). The SF-36 PCS score improved from 43 to 48 (p &lt; 0.001), and the MCS score changed from 28 to 26 (p &gt; 0.05). There was a 100% rate of union of the osteotomy site at the distal tibia and 100% of the grafts showed consolidation at 1 and 2 years postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The TOPIC procedure for large osteochondral lesions of the medial talar dome is an effective technique that resulted in significant improvement exceeding the minimal clinically important difference in pain scores (primary outcome) as well as in other outcomes, with 100% consolidation of the grafts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      Therapeutic\n                      <jats:underline>Level IV<\/jats:underline>\n                      .
