Abstract
Background: This study aimed to determine the prevalence of Blount’s disease (tibia vara) and assess its impact on gait parameters among obese adolescents aged 10 to 19 years in Karachi, Pakistan.
Methodology: A descriptive cross-sectional study was conducted involving 301 obese adolescents recruited from schools and parks in Karachi. Tibia vara was assessed using a universal goniometer, foot strike patterns were evaluated through visual observation, and cadence and stride length were measured using a stopwatch and measuring tape. Data analysis was performed using SPSS version 22. Descriptive statistics and inferential tests were used to evaluate relationships between tibia vara and gait variables.
Results: Among the 301 obese adolescents, 196 were male and 105 were female. Tibia vara was identified in 29.2% (n = 88) of the total sample. Gender-wise, 17.94% (n = 54) of the males and 11.2% (n = 34) of the females were diagnosed with tibia vara.
Conclusion: A considerable number of obese adolescents, particularly males, were affected by tibia vara. Although most maintained a normal gait pattern, deviations in stride length and cadence were noted. These findings emphasize the importance of early screening and rehabilitation strategies, including weight management and gait correction interventions, to prevent long-term functional impairment
