Purpose <p>To elucidate the implications of restoring larger percentage of native ACL tibial insertion area on the functional outcomes and stability of the knee joint after arthroscopic ACL reconstruction.</p> Methods <p>Prospective study of 201 patients with clinical and radiological signs of ACL insufficiency, while individuals with multi-ligamentous injuries, concomitant intra-articular fractures, and revision ACL cases were excluded. Intraoperatively arthroscopic ruler was used to measure the native footprint dimensions and the percentage of native ACL footprint area restored was calculated. The patients were divided into two groups depending upon the percentage of native ACL tibial footprint area restored. Group A patients had &gt; 70% area restored and group B &lt; 70% area was restored. Pre- and postoperatively, patients were assessed using KT1000, Lysholm score, and IKDC score.</p> Results <p>At 1&#xa0;year follow-up, mean IKDC scores at 12&#xa0;months for group A and group B were 89.28 ± 4.74 and 79.22 ± 4.98, respectively (<i>p</i> value &lt; 0.05). The mean Lysholm scores at 12&#xa0;months for Group A and B were 93.68 ± 2.71 and 88.02 ± 2.8, respectively (<i>p</i> value &lt; 0.05). The mean KT1000 scores at 12&#xa0;months for group A (&gt; 70% footprint area restored) and group B (≤ 70% footprint area restored) were 0.37 ± 0.66 and 0.39 ± 0.53, respectively.</p> Conclusions <p>The functional outcomes in terms of IKDC and Lysholm scores were better, while there was no objective difference in the knee laxity when the ACL reconstruction procedure was able to restore more than 70% of the native ACL tibial footprint size.</p>
