Thirty of 33 consecutive knees noted to have grade 3 posterolateral knee complex injuries on preoperative evaluations and examinations under an esthesia underwent arthroscopic evaluation concur rently with open reconstruction. The arthroscopic eval uation revealed a significant number of pathologic changes in the lateral compartment that may have gone undetected if only an open reconstruction had been performed. Tears were identified arthroscopically in 25 (83%) of the anteroinferior, 22 (73%) of the posterosuperior, and 14 (47%) of the posteroinferior popliteomeniscal fascicles. Injuries to the coronary lig ament (80%) and meniscotibial portion of the midthird lateral capsular ligament (73%) were also frequently seen. Other structures injured included the menis cofemoral portion of the posterior capsule (37%), the ligament of Wrisberg (33%), and the meniscofemoral portion of the midthird lateral capsular ligament (10%). Ten avulsions (33%) of the popliteal tendon origin off the femur were also identified. Identification of these injured components greatly facilitated open reconstruc tion of injuries to the posterolateral complex of the knee. All 30 knees were noted to have greater than 1 cm of lateral joint laxity with application of a varus stress. When an unexpected amount of lateral joint laxity is seen arthroscopically (a \"drive-through\" sign) in a patient with suspected ligamentous instability, one should consider a diagnosis of posterolateral knee complex injury.<\/jats:p>","DOI":"10.1177\/036354659702500502","type":"journal-article","created":{"date-parts":[[2007,6,21]],"date-time":"2007-06-21T20:46:52Z","timestamp":1182458812000},"page":"596-602","source":"Crossref","is-referenced-by-count":152,"title":["Arthroscopic Evaluation of the Lateral Compartment of Knees With Grade 3 Posterolateral Knee Complex Injuries"],"prefix":"10.1177","volume":"25","author":[{"given":"Robert F.","family":"LaPrade","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, University of Minnesota, Minneapolis, Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1997,9,1]]},"reference":[{"key":"atypb1","unstructured":"American Medical Association Standard Nomenclature of Athletic Injunes Chicago, American Medical Association, Committee on the Medical Aspects of Sports, 1968, pp 99-100"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197658020-00002"},{"key":"atypb3","doi-asserted-by":"crossref","unstructured":"Hughston JC, Norwood LA Jr The posterolateral drawer test and external rotational recurvatum test for posterolateral rotatory instability of the knee Clin Orthop 147 82-87, 1980","DOI":"10.1097\/00003086-198003000-00014"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.3109\/ort.1981.52.suppl-191.01"},{"key":"atypb5","doi-asserted-by":"crossref","unstructured":"Jakob RP, Warner JP Lateral and posterolateral rotatory instability of the knee, in Jakob RP, Staubli HU (eds) The Knee and Cruciate Ligaments Berlin, Springer-Verlag, 1992, pp 463-494","DOI":"10.1007\/978-3-642-84463-8_53"},{"key":"atypb6","unstructured":"Jobe CM, Pink MM, Jobe FW, et al.
