@entity1 @entity571 @entity3331 @entity158 @entity11989
BACKGROUND: Patellofemoral instability and dysfunction are frequent symptoms in @entity11989 ( @entity11989 ). In this article, the first large series of @entity11989 @entity1 is presented in which these knee symptoms were assessed using validated outcome scores. Additionally, the need for surgical interventions, percentage of @entity1 who received surgical treatment and @entity1 reported outcomes are reported. METHODS: A questionnaire based survey was conducted in 139 Dutch @entity11989 @entity1 . Symptoms of the knees were assessed by the @entity3331 and @entity571 Outcome Score (KOOS) and Kujala knee score. The questionnaire addressed whether surgical intervention was currently considered, history of past surgeries, type of surgical procedures performed and results of these procedures. RESULTS: Response rate was 74%. Mean KOOS (73.04) and Kujala (74.01) scores showed a wide range and variability between @entity1 . Patellofemoral instability was present in 48.5% of @entity1 . Surgical intervention was currently considered by 12% of @entity1 . Their KOOS and Kujala scores were significantly lower compared to those not considering surgery and they experienced more patellar instability. Surgery was performed on 31 knees in 23 @entity1 . KOOS and Kujala scores were lower in surgically treated versus nonoperated @entity1 but no difference in patellar instability was present. An improvement in @entity158 in 87% and in function in 30% of knees was reported after surgery. @entity1 satisfaction with the surgical results was 61% and 10% was dissatisfied. Patellar realignment procedures showed similar results, although persistent patellar instability was reported in 40% of @entity1 , not different from nonoperated @entity1 . CONCLUSIONS: Knee symptoms in @entity11989 @entity1 vary widely, with patellar instability present in nearly half of the @entity1 . Although surgical treatment appears unfavourable as surgically treated @entity1 have lower KOOS and Kujala scores, the @entity1 reported surgical results are generally good with a high @entity1 satisfaction. LEVEL OF EVIDENCE: Level IV.
