Association between the lower extremity biomechanical factors with osteoarthritis of knee

Abstract

Introduction: Osteoarthritis (OA) of the knee joint is one of the causes of pain and physical disability. Our aim is to prevent the OA of the knee joint. Hence, to prevent and to treat, the OA knee pain needs to find an association between various biomechanical factors of the lower limb and OA knee pain. Therefore, to assess the association between the lower extremity biomechanical factors with osteoarthritis of knee pain. Materials and Methods: Our study was a cross-sectional study, in that we have taken fifty participants who already diagnosed OA. The various biomechanical factors of the lower limb were measured along with outcome scales such as the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for the OA knee and Numeric Rating Scale (NRS) for the knee pain from each participant. Results: There was a significant correlation found between femoral anteversion and navicular drop with WOMAC scale with a P = 0.001 and 0.03, respectively. The significant correlation between femoral anteversion, hamstring muscle length, Q angle (dynamic), and tibial torsion with NRS pain scale with P = 0.07, 0.06, 0.07, and 0.06, respectively. Conclusion: The study concluded that body mass index, femoral anteversion, hamstring's length, navicular drop, tibial torsion, and Q angle (dynamic) are various biomechanical factors which might be responsible for the incidence of the OA knee along with functional limitation and OA knee pain.
