A recent study conducted by researchers at the University of Hong Kong examined the relationship between foot and knee deformities and functional limitations and osteoarthritis (OA). The study included 1253 participants and found that foot pain was associated with functional limitations and falls, while varus knee was associated with incident OA. The prevalence of hallux valgus, foot pain, and varus knee were 33.1%, 35.1%, and 25.8% respectively. The study suggests that foot pain and varus knee are important factors to consider in relation to functional limitations and OA. [Extracted from the article]

A recent research study conducted by Huazhong University of Science and Technology aimed to understand the genetic association between knee osteoarthritis (KOA) and hallux deformities, specifically hallux valgus (HV) and hallux rigidus (HR). The study collected summary-level statistics from genome-wide association studies and used two-sample Mendelian randomization to analyze the causal relationship between KOA and HV or HR. The results showed that KOA has a causative influence on HV and HR, but hallux deformities did not appear to be the cause of KOA. The study suggests that these findings can provide evidence-based recommendations for reducing the incidence of hallux deformities in KOA patients. Further research is needed to validate these associations and explore their broader implications. [Extracted from the article]
