title: [Prevalence of knee osteoarthritis in Hungary. Study conducted in a representative Hungarian population].
abstract: In an earlier publication, authors have already reported the result of a survey conducted in a representative Hungarian population, where joint complaint prevalence data were presented, including those of the knee joint.
  
  
  OBJECTIVE
  Following the above mentioned publication, in the current study authors aimed to determine the clinical and radiological prevalence of knee osteoarthritis using internationally accepted scoring methods for evaluation.
  
  
  METHODS
  2422 patients with complaints and consent were invited for a clinical follow up. 682 people (244 male; 438 female) came to participate in the study. After recording case history, and anthropometric parameters, a thorough musculoskeletal examination was carried out. Using these data Knee Society Score, Functional score and visual analogue pain scale values were calculated. On the AP and lateral view X-rays joint space width was measured, Kellgren-Lawrence radiological evaluation was performed and osteoarthritis prevalence was defined.
  
  
  RESULTS
  radiological evaluation was possible in 676 cases. Knee osteoarthritis was found in 91 people (13.3%), severe osteoarthritis in 20 people (2.9%). Functional parameters of radiologically negative and positive cases were compared. Knee Society Score, functional score and visual analogue scale values were significantly worse in people with defined osteoarthritis (p<0.05). Regarding Body Mass Index, significantly higher values were found in those with osteoarthritis as well.
  
  
  CONCLUSIONS
  Authors presented radiographic knee osteoarthritis prevalence data for the first time in the Hungarian literature. According to their observations, age and higher BMI values play a significant role in the development of knee osteoarthritis. After discussing the details of the survey, an overview and comparison with data of international literature is given.
