Conventional spin echo, proton density, and T2\u2010weighted double echo sequences were obtained, as well as T2\u2010weighted fat\u2010saturated fast spin echo sequences. All but one of the screws (19 of 20) were evident in all serial scans. These showed minimal decrease in size over time. The one screw that had completely disappeared 8 months after reconstruction had cracked during insertion. None of the reconstructed ACL grafts showed clinical instability, persistent effusions, or detectable adverse reactions to the screws. Two patients developed abnormal signal in the tibial tunnel: one developed fluid anterior to the graft, and the other developed increased signal within the graft. The abnormal signal resolved with time in both patients. Other than the preceding changes, no abnormalities were detected on conventional sequences. Fat\u2010saturated fast spin echo sequences showed a variable amount of increased signal around the tunnels, suggesting edema or fibrovascular marrow changes. The changes noted near the tunnels on the fat\u2010suppressed scans most probably represent a general reaction to surgical insult rather than a reaction to the bioabsorbable screws, as similar changes were noted at the patellar harvest site.<\/jats:p>","DOI":"10.1053\/ar.1999.v15.015047","type":"journal-article","created":{"date-parts":[[2005,1,3]],"date-time":"2005-01-03T12:58:08Z","timestamp":1104757088000},"page":"474-480","source":"Crossref","is-referenced-by-count":76,"title":["Magnetic Resonance Imaging of Bioabsorbable Polylactic Acid Interference Screws During the First 2 Years After Anterior Cruciate Ligament Reconstruction"],"prefix":"10.1002","volume":"15","author":[{"given":"William H.","family":"Warden","sequence":"first","affiliation":[{"name":"Southern California Center for Sports Medicine Long Beach California U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Friedman","sequence":"additional","affiliation":[{"name":"Southern California Center for Sports Medicine Long Beach California U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louis M.","family":"Teresi","sequence":"additional","affiliation":[{"name":"Southern California Center for Sports Medicine Long Beach California U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Douglas W.","family":"Jackson","sequence":"additional","affiliation":[{"name":"Southern California Center for Sports Medicine Long Beach California U.S.A."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[1999,7,1]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0749-8063(95)90129-9"},{"key":"e_1_2_2_3_1","first-page":"349","article-title":"Comparison of bioabsorbable and metal screw interference screw in anterior cruciate reconstruction (a clinical trial) Presented at the 14th Annual Meeting of the Arthroscopy Association of North America, San Francisco, CA, May 4\u20107, 1995","volume":"11","author":"Johnson LL.","year":"1995","journal-title":"Arthroscopy"},{"key":"e_1_2_2_4_1","first-page":"680","article-title":"Synovitis of the knee after intraarticular fracture fixation with Biofix7: Report of two cases","volume":"63","author":"Barford G","year":"1992","journal-title":"Acta Orthop Scand"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.72B4.2199452"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198901000-00028"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.74B6.1332974"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453679209154859"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453679209154762"},{"key":"e_1_2_2_10_1","first-page":"381","article-title":"Bioresorbable interference screws in ACL\u2010surgery.
