INTRAOPERATIVE CLINICAL TEST FOR KINEMATIC ASSESSMENT OF ACl GRAFT BEHAVIOUR WITH COMPUTER ASSISTED PROCEDURE
Keywords: kinematic evaluation, anterior cruciate ligament
AbstractThis paper describes a protocol for an accurate and extensive computer-assisted in vivo evaluation of joint laxities durinQl reconstructions of anterior cruciate ,ligament (ACL). The operating technique is a double bundle with over the top graft. Kinematic tests are performed, intraoperatively, before the ACL reconstruction, with ACL deficient knees, and after the ACL reconstruction. Results of first four in vivo cases, highlight that the reconstruction gives a complete restore of stability, in the antero-posterior direction, at 30° and 90° degrees giving and increased stability up to 73%, confirming the role of the ACL in the control of AP dislocation. Internal and external rotations were also satisfactorily restored after the graft fixation; in particular at 30° of tlexion, the reconstruction gives a good control of the joint, reducing laxity up to 43%.
