The AIFP outputs during anterior shear loading of the knee joint using these two calibration methods were compared directly to graft force measurements using a ligament cutting protocol and a 6 DOF load cell. The mean percent error ((actual \u2013 measured)\/(actual) * 100) associated with the pre-implantation calibration ranged between 85 and 175 percent, and was dependent on the knee flexion angle tested. The percent error associated with the post-implantation technique was evaluated in two load ranges: loads less than 40 N, and loads greater than 40 N. For graft force values greater than 40 N, the mean percent errors inherent to the post-implantation calibration method ranged between 20 and 29 percent, depending on the knee flexion angle tested. Below 40 N, these errors were substantially greater. Of the two calibration methods evaluated, the post-implantation approach provided a better estimate of the ACL graft force than the pre-implantation technique. However, the errors for the post-implantation approach were still high and suggested that caution should be employed when using implantable force probes for in vivo measurement of ACL graft forces.<\/jats:p>","DOI":"10.1115\/1.2798336","type":"journal-article","created":{"date-parts":[[2008,2,21]],"date-time":"2008-02-21T20:48:52Z","timestamp":1203626932000},"page":"393-398","update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":17,"title":["Calibration and Application of an Intra-articular Force Transducer for the Measurement of Patellar Tendon Graft Forces: An in Situ Evaluation"],"prefix":"10.1115","volume":"121","author":[{"given":"B.
