RESUMO
ObjectiveTo evaluate the value of the measurement with a scale in arthroscopic anatomic anterior cruciate ligament (ACL) reconstruction.Methods Thirty-six patients with unilateral ACL-deficient knees were divided into single bundle group and double bundle group based on the length of the major axis of the native ACL footprint measured with a scale.Consistent with the International Knee Documentation Committee (IKDC) scoring systems,Lysholm knee scoring scale and Tegner activity rating were used to evaluate the clinical results,and data from 23 to 26 months follow-up were gathered and analyzed statistically.ResultsIn terms of IKDC evaluation,19 patients( 90.4％ ) in the double band group and 13 patients( 86.7％ )in the single band group were graded as normal or nearly normal ( Z =7.82,6.33 ; P ＜ 0.05 ).The mean Lysholm scores were 93.8 ± 9.9 and 94.2 ± 9.6 and the mean Tegner scores were 6.6 ± 1.9 and 6.5 ± 1.7 for the double and single band groups,respectively( t =2.31,5.60,3.55,7.09 ;P ＜0.05 ).ConclusionArthroscopic measurement with a scale combined with other traditional methods to determine the tunnel location is easy to conduct and intuitional to understand.It could be useful in anatomic ACL reconstruction.
