Background: Knee dislocations are uncommon (<0.5% of all dislocations); however, they may result in catastrophic outcomes secondary
to their high‑energy nature and neurovascular injuries. Objectives: The objective of this study was to evaluate the clinical outcome of
knee dislocation management. Subjects and Methods: A total of 20 consecutive adult patients with knee dislocation were enrolled in this
cross‑sectional study between 2011 and 2014. A single knee surgeon examined all the patients for knee instability for subjective evaluation of
knee function using the Lysholm Knee Questionnaire, Knee Society Score (KSS), and Short Form‑36 (SF‑36). Results: The average Lysholm
Knee Scores and KSS were 68 (range: 18–100) and 65 (range: 15–97), respectively. All domains of SF‑36 among the studied patients were
lower than that of the normal population. We could not find any correlation between age, body mass index, and interval between initial trauma
and operation with outcome variables (Lysholm Knee Score, KSS, and SF‑36 Physical Component Score, and SF‑36 Mental Component
Score). Conclusions: The knee function after proper management of dislocation is reasonable, but prolonged course of management and
multiple operations may decrease the patients’ quality of life.
