Introduction:The American Academy of Orthopaedic Surgeons (AAOS) published a series of evidence-based guidelines for treatment of knee osteoarthritis (OA). We studied compliance with these guidelines among orthopaedic surgeons.Methods:We sent a survey to members of the American Association of Hip and Knee Surgeons. It included five clinical vignettes based on the Kellgren-Lawrence radiographic system for classification of knee OA. Respondents selected treatment currently supported or not supported by the AAOS guidelines.Results:Of 345 responses, the frequency of use of recommended interventions was 80%, 82%, 21%, 50%, and 98% for OA at stages 0 through 4, respectively. For stage 2 and stage 3 OA, intra-articular hyaluronic acid was the most commonly selected intervention not recommended by the AAOS.Discussion:Apparently, AAOS guidelines on the treatment of OA have not reached the orthopaedic community, resulting in lack of treatment consensus and continued use of modalities with no proven patient benefits.Conclusions:Management of moderate to severe knee OA does not align with AAOS guidelines. We encourage researchers to conduct clinical trials to identify the role of intra-articular corticosteroids in treating this condition.
