Abstract

Background: An essential clinical parameter related to gait is foot progression angle (FPA). The objective of this study was to evaluate foot progression angle difference between Kl grade 2 and 3 in osteoarthritis knee patients and understanding biomechanical factors associated knee OA.

Methods: Study was conducted on 108 patients diagnose with osteoarthritis knee according to EULAR classification knee OA. Age, gender and BMI were recorded, gait analysis was done to evaluate difference in FPA between OA knee patients with KL grade 2 and 3.

Results: The 108 patient, 68 female and 40 males with osteoarthritis knee were included in study. Mean age of patients was 55.92±0.8 year, mean BMI was 27.24±0.4 kg/m2. Mean and SD of FPA in male 7.31±3.60 and   in female 8.31± 4.18 in patients with Kl grade 2 and 3 mean difference between male and female FPA is -0.99 with 95% CI, p=0.43 and t=0.78. In KL grade 3, FPA mean and SD of male 6.79±2.80 and female 7.62±9.10, t=0.9, mean difference -0.83 with 95% CI and p=0.6925.

Conclusions: This study suggests, females in comparison to males have less FPA and therefore, females are more prone in progression of knee OA. Potential confounders including age, gender, BMI disease severity did not alter magnitude, although 95% CI.
