[Knee luxation--follow-up after surgery].

Background: Traumatic dislocation is the most severe ligamentous injury of the knee. The traditional definition of knee dislocations has been expanded to include bicruciate knee injuries with one or both lateral ligaments injured, even when the knee is reduced on initial presentation. Surgical treatment is internationally well accepted.

Material And Methods: From 1996 to 2002, 87 patients with knee dislocation were treated in our department. In this prospective study, 55 patients were followed up with functional knee tests a minimum of one year (mean: 3.5 years) after surgical treatment.

Results: 59% of the injuries were high-energy traumas. Mean age was 34 (12-80). 57% of the patients achieved excellent to good results on the Lysholm Score.

Interpretation: Positive prognostic factors are likely to be age less than 40 at the time of the accident or sports-related injury. Fifty-four of the 55 patients in the follow-up study had returned to work or studies after one year. Dislocated knee is not only related to high-energy and traffic injuries; it also occurs in low-energy trauma and sports injuries.
