Background: Knee osteoarthritis (KOA) is a degenerative joint disease, often associated with age and body mass index (BMI), critical demographic factors influencing its progression. The Foot Progression Angle (FPA), a measure of foot alignment, has been studied as a potential contributor to the development and progression of KOA.

Method: A comprehensive prospective analysis investigated the relationship between age, BMI, and FPA in individuals diagnosed with KOA. The study included data from participants categorized based on their Kellgren-Lawrence (K/L) grades: K/L grade II and K/L grade III. Correlation coefficients (R) and pvalues were meticulously calculated to assess these relationships' strength and statistical significance.

Results: Our correlation analysis inKOA (K/LII and III) showed weak, non-significant correlations between age, BMI, and FPA. Specifically, age was linked with FPA at -0.1415 (pvalue 0.3499) in K/L 2 and -0.1257 (p value 0.33) in K/L grade 3, while BMI correlations were -0.125 (pvalue 0.40) in K/L 2 and -0.1402 (p value 0.27) in K/L 3.

Conclusion: While BMI and age are significant factors in KOA, their relationship with FPA is weak and insignificant. This finding paves the way for further research to explore other biomechanical factors that may play a more substantial role in knee OA progression.

Aavrati Rastogi is an eminent clinical researcher, academic author, and musculoskeletal specialist at the All India Institute of Medical Sciences (AIIMS), Rishikesh, India , where she has significantly advanced the field of orthopedic science through her high-precision research into clinical gait analysis, kinetics, and kinematics, alongside the longitudinal management of Knee Osteoarthritis (KOA).Her professional influence is further established by her authorship of the authoritative textbook, Consize Notes of Electrotherapy, a critical resource bridging theoretical clinical physics with applied rehabilitation. Her work has garnered international recognition for pioneering evidence-based protocols that integrate regenerative medicine with the validation of culturally specific patient-reported outcome measures for the Indian demographic. Her research is uniquely characterized by its focus on the psychosomatic dimensions of orthopedic injuries—specifically identifying "ACL depressive syndrome" and the systemic impact of chronic joint pain on mental health—and her scholarly rigor is evidenced by the dissemination of clinical findings at numerous prestigious national and international medical conferences. By synthesizing advanced physiological data with holistic recovery strategies, she continues to redefine the standard of care in evidence-based musculoskeletal medicine.
