Chondral damage on arthroscopy was classified in grades 1\u20133 modified after Outerbridge. The radiographic evaluation was done according to Ahlb\u00e4ck classification. Twenty\u2010eight patients (44%) did not show any significant chondral damage on arthroscopy (grades 0\u20131). The radiographic findings in this group were usually normal. Three patients, however, showed a slight narrowing of the medial joint space (Ahlb\u00e4ck 1). All three had severely degenerated menisci, and two of them showed superficial fibrillation of both the tibia and the femur. Twenty\u2010four patients (38%) showed a partial thickness chondral damage with fragmentation of the surface (grade 2). Radiographic findings were usually normal; however, patients with involvement of both the tibia and the femur often showed a joint space narrowing on radiographs. Eleven patients (18%) showed destruction of the cartilage down to subchondral bone (grade 3). The typical radiographic finding was a joint space obliteration (Ahlb\u00e4ck II). Involvement also of the lateral compartment as assessed on arthroscopy was significantly more common in patients with 2nd and 3rd degree chondral disease and Ahlb\u00e4ck II and III on radiographs than in those with 2nd and 3rd degree chondral damage and normal radiographs. In all but one of the patients with involvement of both compartments, the lateral compartment was considered normal on radiographic examination.<\/jats:p>","DOI":"10.1016\/s0749-8063(87)80058-0","type":"journal-article","created":{"date-parts":[[2006,7,22]],"date-time":"2006-07-22T07:16:08Z","timestamp":1153552568000},"page":"161-165","source":"Crossref","is-referenced-by-count":70,"title":["The correlation between osteoarthrosis as seen on radiographs and on arthroscopy"],"prefix":"10.1002","volume":"3","author":[{"given":"Jack","family":"Lysholm","sequence":"first","affiliation":[{"name":"From the Department of Orthopaedic Surgery University Hospital S\u2010581 85 Link\u00f6ping Sweden"}]},{"given":"Per","family":"Hamberg","sequence":"additional","affiliation":[{"name":"From the Department of Orthopaedic Surgery University Hospital S\u2010581 85 Link\u00f6ping Sweden"}]},{"given":"Jan","family":"Gillquist","sequence":"additional","affiliation":[{"name":"From the Department of Orthopaedic Surgery University Hospital S\u2010581 85 Link\u00f6ping Sweden"}]}],"member":"311","published-online":{"date-parts":[[1987,1,1]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"131","volume-title":"Atlas of arthroscopy","author":"Watanabe M","year":"1968"},{"key":"e_1_2_1_3_1","first-page":"87","volume-title":"Arthroscopy of the knee","author":"Jackson R","year":"1976"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453677809050095"},{"key":"e_1_2_1_5_1","first-page":"7071","volume-title":"Diagnostic and surgical arthroscopy","author":"Johnson L","year":"1981"},{"key":"e_1_2_1_6_1","first-page":"14","volume-title":"Arthroscopy","author":"O'Connor RL","year":"1977"},{"key":"e_1_2_1_6_2","first-page":"143","volume-title":"Arthroscopy","author":"O'Connor RL","year":"1977"},{"key":"e_1_2_1_7_1","unstructured":"Oretorp N.On the diagnosis and treatment of meniscus and ligament injuries in the knee especially on the medial side.
