E-poster #381 Gait Analysis in Well and Poor Functioning Patients with an Anterior Cruciate Ligament Deficiency Joanna Kvist, SWEDEN, Presenter Physical Therapy / IHS, Linkoping, SWEDEN Introduction: Some patients with ACL-deficiency can function well and participate in high-level sports, while others have functional limitations even during activities of daily living. We have previously found that patients, who function well after an ACL-injury, have similar static translation in the injured leg compared to poor functioning patients. However, they utilize a greater anterior translation during gait. The aim of the present study was to investigate if the anterior positioning of the tibiae in the well-functioning patients was assisted dynamically by the neuromuscular system. Material and Method: Twenty-one patients with a unilateral ACL injury participated in the study. Twelve patients functioned well (Lysholm score >=84) and 9 patients had poor knee function (Lysholm score
Evaluation of Antero-posterior and Rotatory Instability after Anteior Cruciate Ligament Reconstruction Hiroki Yamashita, Kanagawa JAPAN, Presenter Yujiro Mori, Kanagawa JAPAN Hiroshi Takagi, Kanagawa JAPAN Toshiro Yonezawa, Kanagawa JAPAN Akihiko Fujimoto, Kanagawa JAPAN Showa Univ. Fujigaoka Rehab. Hosp, Yokohama, JAPAN The purpose of this study was to dynamic evaluate the remaining knee instability after anterior cruciate ligament (ACL) reconstruction. Knee Motion Analyzer (CA4000) was used to evaluate postoperative ACL stability. Seventy-one patients who underwent ACL reconstruction by the modified over-the-top method using a Kennedy LAD reinforced patellar tendon. Twenty-five patients who had remaining knee instability after ACL reconstruction. There were 13 males and 12 females with a mean of 28 years. The results of knee instability were classified into the following three types. Type A: eight patients had both antero-posterior(A-P) instability and rotatory instability. Type B: eleven patients had only rotatory instability. Type C: six patients remained only A-P instability. The results of our study showed that remaining three types of instability after ACL reconstruction. We concluded that it was necessary to evaluate both antero-posterior stability and rotatory stability when doing the evaluation of knee stability after ACL reconstruction. E-poster #384 Effect of Vision on Postural Sway in Anterior Cruciate Ligament Injured Knees Kazuhiro Okuda, Okayama, JAPAN, Presenter Nobuhiro Abe, Okayama, JAPAN Masuo Senda, Okayama, JAPAN Yoshimi Katayama, Okayama, JAPAN Hiroyuki Hashizume, Okayama, JAPAN Hajime Inoue, Okayama, JAPAN Okayama University graduate school, Okayama, JAPAN Introduction: It is well known that proprioception is reduced in the ACL deficient knee. After ACL injury, the knee in some patients may suddenly give way during walking. All of the factors and their roles are not clarified. We measured and compared postural sway during one-leg standing with eyes open and closed to assess the difference between injured and non-injured leg. Material and Methods: We examined 32 patients (17 men and 15 women) with ACL injury before surgery from March 2001 through January 2004. Their mean age at the time of injury was 22.0 years old (range 15 to 40 years), the mean height was 166.9 cm (range 152 to 183cm), the mean body weight was 64.4 kg (range 50 to 97kg), and the mean period from the injury to the test was 4.2 months (range 2 to 11 months). Ipsilateral and contralateral legs were tested in each patient. None of them presented obvious dysfunction in the lower limbs, or central nerve system. Using a gravicoder, we measured the factors of the postural sway (local length per time, and environmental area) in two legs and one leg standing tests with eyes open or with eyes closed. Knee laxity was measured by KT2000 (MED metric, San Diego, CA). Results and Conclusion: In the ACL injured knee, the amplitude of postural sway increased significantly when standing on one foot with closed eyes, but did not increase significantly with open eyes. There were no significant differences with respect to sex or the presence or absence of joint laxity. There was little correlation between movements and the anterior drawer distance measured by KT2000, or the ratio of injured side to non-injured side in knee muscle strength. We found that knee stability in ACL injured patients was lower in the injured leg with eyes closed and that vision appears to be dominant in compensating for the decreased contribution of the injured ACL. E-poster #385 Endoscopic 3D Insertion Geometry of the Two Functional Bundles of the ACL. Ate Wymenga, Nijmegen, NETHERLANDS, Leendert Blankevoort, Amsterdam, NETHERLANDS Jan Kooloos, Nijmegen, NETHERLANDS Joan Luites, NETHERLANDS, Presenter Sint Maartenskliniek, Nijmegen, NETHERLANDS Introduction. The anterior cruciate ligament (ACL) consists of an anteromedial bundle (AMB), thight in flexion and a posterolateral bundle (PLB), tensed near extenson. Restoring this functional twobundled nature through a double bundle anatomic reconstruction asks for a surgeonoriented description of the insertion geometry from an endoscopic view.
