Abstract:
Background: This study was conducted to find out the age
when tibiofemoral angle starts to be in valgus and reaches
maximum angle. The differences of the angles between
genders were also studied.
Methodology: This cross sectional study on tibiofemoral
angle was conducted among 160 normal healthy children
using clinical measurement method. The children between 2
18 months to 6 years old were assigned to 5 specific age
groups of 32 children with equal sex distribution.
Result: This study had shown a good inter-observer
reliability of tibiofemoral angle measurement with intraclass
correlation coefficient (ICC) of 0.87 with narrow
margin of 95% confident interval (95% CI: 0.73, 0.94). The
mean tibiofemoral angle for children at 2 , 3 , 4 , 5 and 6
years old were 2.25o (SD=0.53), 8.73o (SD=0.95), 7.53o
(SD=1.40), 7.27o (SD=1.14) and 6.72o (SD=0.98)
respectively. The age when they achieved maximum valgus
tibiofemoral angle was 3 years old. The maximum mean
(SD) tibiofemoral angle for boys, girls and all children were
8.91o (SD=1.17) , 8.56o (SD=0.62) and 8.73o (SD=0.95)
respectively. The mean tibiofemoral angle showed no
statistically significant difference between girls and boys
except for the 5-year-old group, in which the mean TF angle
for girls was 7.560 (SD=0.95) and for the boys was 6.970
(SD=1.26) with p-value of 0.037.
Conclusion: Measurement of tibiofemoral angle using the
clinical method had a very good inter-observer reliability.
The tibiofemoral angle in Malay population was valgus since
the age of 2 years with maximum angle of 8.730 (SD=0.95)
achieved at the age of 3 years.
