One such fixation technique is the lift-drill-fill-fix (LDFF) procedure, which has shown reliable long-term results in an arthroscopic approach; however, the outcomes in cases treated through an open approach are unknown.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose:<\/jats:title>\n                    <jats:p>To assess the 2-year outcomes after open LDFF for chronic OLT.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Study Design:<\/jats:title>\n                    <jats:p>Case series; Level of evidence, 4.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A total of 34 patients who underwent an open LDFF procedure for chronic (&gt;6 weeks) OLT were prospectively followed for 2 years. The primary outcome concerned the comparison in numeric rating scale of pain (0 = no pain; 10 = most severe pain) during walking between the preoperative score to the 2-year postoperative follow-up score. The association of baseline factors with the change in the primary outcome between baseline and 2-year follow-up was assessed. Secondary patient-reported outcome measures (PROMs) were the Foot and Ankle Outcome Score and 36-Item Short Form Health Survey (SF-36). The fragment union rate on 1-year follow-up computed tomography scans and the influence of possible baseline factors on union were assessed. Adverse events, including revision surgery and complications, were assessed and documented.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The primary outcome significantly improved from a median of 6 (IQR, 4-7) out of 10 preoperatively to 1 (IQR, 0-3) out of 10 at final follow-up,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .01.

All other PROMs significantly improved, except for the SF-36 Mental Component Summary. The fragment union rate was 91% [95% CI, 76-98].
