The injury was classified according to Schenck's classification. The autografts used were hamstrings and\/or bone tendon grafts, as appropriate to the injury pattern. A 1\u2010year postoperative 3 Tesla magnetic resonance imaging was used for the assessment of graft maturation according to Howell's score (1\u20104) and tunnel widening. Maturation status was assessed for each ligament and compared with ACL graft maturation. Correlations between graft maturation and clinical laxity was analyzed. Tunnel widening was analyzed for each reconstructed ligament. The impact of different graft fixation systems on maturation was also evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 72 patients were included, with 215 ligaments reconstructed. Howell and I scores were found in 85% of ACL, 37.5% of posterior cruciate ligament, 97% of medial collateral ligament, 92% of posterior oblique ligament, 100% of lateral collateral ligament, and 81% of popliteal tendon grafts. ACL graft maturation was greater than posterior cruciate ligament maturation (\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .001).
