All the redislocations occurred in female patients. The patients with recurrence also suffered first\u2010time patellar dislocation in their unoperated knee during the follow\u2010up significantly more often (<jats:italic>P<\/jats:italic>&lt;0.01) than the patients with stable knees. Patients with redislocations were more often dissatisfied with their outcome than the stable group, mainly because of annoying anterior knee pain (<jats:italic>P<\/jats:italic>&lt;0.05). Preoperatively the patients with redislocation had had more pronounced pathological patellofemoral congruity (Laurin's projections) in both the operated knee (<jats:italic>P<\/jats:italic>&lt;0.05) and the, at that time uninjured, control knee (<jats:italic>P<\/jats:italic>&lt;0.05). To improve the results of operative treatment for acute patellar dislocation, surgery should be aimed at correcting the underlying pathology. In grossly and symmetrically pathological cases of patellofemoral articulation, a distal realignment procedure should be considered. Otherwise conservative treatment may be justified.<\/jats:p>","DOI":"10.1007\/bf01565461","type":"journal-article","created":{"date-parts":[[2005,4,27]],"date-time":"2005-04-27T14:23:54Z","timestamp":1114611834000},"page":"100-103","source":"Crossref","is-referenced-by-count":41,"title":["Prospective long\u2010term results of operative treatment in primary dislocation of the patella"],"prefix":"10.1002","volume":"1","author":[{"given":"A.","family":"Harilainen","sequence":"first","affiliation":[{"name":"<!--<label>1<\/label>--> The Orthopaedic Hospital of the Invalid Foundation Helsinki Finland"},{"name":"<!--<label>2<\/label>--> Jorvi Hospital Espoo Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Sandelin","sequence":"additional","affiliation":[{"name":"<!--<label>1<\/label>--> The Orthopaedic Hospital of the Invalid Foundation Helsinki Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[1993,6]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.74B1.1732244"},{"key":"e_1_2_1_3_2","doi-asserted-by":"crossref","first-page":"182","DOI":"10.1097\/00003086-197810000-00025","article-title":"Acute patellar dislocation: results of immediate surgical repair","volume":"136","author":"Boring TH","year":"1978","journal-title":"Clin Orthop"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1177\/036354658801600308"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198405000-00028"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198405000-00028"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-197707000-00007"},{"key":"e_1_2_1_8_2","first-page":"178","article-title":"Operative treatment in acute patellar dislocation: radiological predisposing factors, diagnosis and results","volume":"1","author":"Harilainen A","year":"1988","journal-title":"Am J Knee Surg"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/036354658601400204"},{"key":"e_1_2_1_10_2","first-page":"238","article-title":"Acute traumatic dislocation of the patella treated by simple medial capsulorrhaphy","volume":"142","author":"Hejgaard N","year":"1980","journal-title":"Ugeskr Laeg"},{"key":"e_1_2_1_11_2","first-page":"346","volume-title":"Disorders of the knee","author":"Helfet AJ","year":"1982"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1148\/101.1.101"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-198502000-00014"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198211000-00023"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197860010-00007"},{"key":"e_1_2_1_16_2","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1097\/00003086-197910000-00004","article-title":"The tangential X\u2010ray investigation of the patellofemoral joint: X\u2010ray technique, diagnostic criteria and their interpretation","volume":"144","author":"Laurin CA","year":"1979","journal-title":"Clin Orthop"},{"key":"e_1_2_1_17_2","doi-asserted-by":"crossref","first-page":"88","DOI":"10.1097\/00003086-197903000-00014","article-title":"Acute dislocation of the patella in children.
