The graft was placed on the femoral site in the \u201chigh noon\u201d position combined with a slight medial tibial tunnel placement. The resulting anterior\u2010posterior cruciate ligament impingement near extension caused a persistent functional extension deficit of 20\u00b0. Under anesthesia, the extension loss diminished, and thus it was hypothesized that the ACL\u2010PCL impingement during extension activates a proprioceptive reflex leading to a functional extension loss while the patient is awake. After sacrifice of the graft and subsequent replacement of the ACL, full range of motion was achieved within 2 months. After a 3\u2010year postinjury history of 3 arthroscopies and 2 ACL reconstructions, the athlete reached her preinjury activity level again. This rare cause of a reflex extension loss due to femoral high noon graft placement has not been described previously and should be included as a differential diagnosis when evaluating patients with an extension deficit after ACL reconstruction.<\/jats:p>","DOI":"10.1053\/jars.2001.21821","type":"journal-article","created":{"date-parts":[[2002,8,24]],"date-time":"2002-08-24T23:46:10Z","timestamp":1030232770000},"page":"408-411","source":"Crossref","is-referenced-by-count":35,"title":["Reflex
