The PCL and avulsion bony fragment was fixed with 2 No. 6 polyester sutures, which were pulled out through Y\u2010shaped bone tunnels and fixed on a titanium button. The 2 branch openings of the Y\u2010shaped bone tunnels were at the posterior edge of the tibial bed; the common outer opening was at medial side of the tibial tubercle. Through twisting of the button, the suture were tightened to ensure the fixation. The patients were followed\u2010up for more than 2 years and were evaluated according to the International Knee Documentation Committee, Lysholm, and Tegner rating scales.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      There was no extension limitation. Except for 2 patients who had 5\u00b0 flexion limitation, all the patients gained normal flexion. Before surgery, all patients had 1\u00b0 to 2\u00b0 positive posterior drawer test, and KT\u20101000 examination showed that the side\u2010to\u2010side difference of the posterior drawer test was 7 to 14 mm, with an average of 10.3 \u00b1 1.7 mm. At the last follow\u2010up, 1 patient had 1\u00b0 positive posterior drawer test, the other patients had negative posterior drawer tests. The side\u2010to\u2010side difference of the posterior drawer test was 0 to 2 mm in 28 patients, and 4 mm in 1 patient, with an average of 0.6 \u00b1 0.4 mm. The Lysholm score was 93 to 100, with an average of 97.4 \u00b1 1.4. The Tegner scores were 6.8 \u00b1 0.8 before injury, and 6.6 \u00b1 0.7 at the last follow\u2010up (\n                      <jats:italic>P<\/jats:italic>\n                      &gt; .05).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Arthroscopic treatment of acute tibial avulsion fracture of the PCL with this fixation technique can restore the stability and function of the joint in most patients.
