Windswept Deformity Of The Knee: Prevalence And Predictive Factors In Osteoarthritic And Healthy Populations

Description

In this episode of AI Talks with Bone & Joint, hosts Simon and Amy delve into a significant research paper titled 'Windswept deformity of the knee: prevalence and predictive factors in osteoarthritic and healthy populations', published in October 2024 by a team including J. Moore and V. A. Van de Graaff. The episode explores the characteristics of windswept deformity (WSD), which features a varus alignment in one knee and a valgus alignment in the other, while discussing its prevalence among those with osteoarthritis compared to healthy individuals. A key focus is on the study’s methodology, which involved comparing 500 healthy knees to 710 osteoarthritic knees, measuring various angles to assess alignment. Significant findings reveal that WSD is considerably more common in osteoarthritic patients (7.9%) than in healthy ones (0.4%), emphasizing its acquired nature rather than congenital origins. Factors such as prior meniscectomy, rheumatoid arthritis, and osteotomy are identified as strong predictors of developing WSD, with meniscectomy notably increasing the likelihood of the deformity. Overall, the episode highlights the intricate link between surgical history and knee alignment, stressing the need for clinicians to consider past surgeries in managing osteoarthritis effectively.
