Relationship between Body Mass Index And Knee Alignment Using Non-Radiographic / Umbilical Method
Relationship Between Body Mass Index And Knee Alignment
Keywords:
Body mass index, knee alignment, knee osteoarthritis, correlationAbstract
Aim: The aim of the research was to investigate the relationship between body mass index and knee alignment angle using non-radiographic methods, and to propose a regression equation to define the relationship.Method: A total of 300 students (200 males, 100 females) of Nnamdi Azikiwe University, Nnewi campus participated in the study. Knee alignment was measured using body landmarks (umbilicus, right knee and right second toe) with a goniometer and calliper; the body mass index was also determined.Result: The male subjects had a mean body mass index of 24.2 kg/m2 and knee alignment angle of 176.5o. The female participants had a mean body mass index of 22.7 kg/m2 and knee alignment angle of 180.9o. Body mass index had no significant relationship with knee alignment in both males and females respectively (r = 0.009, p > 0.05; r = 0.065, p > 0.05). Conclusion: The study showed no significant positive relationship between body mass index and knee alignment, and body mass index is therefore not a good determinant for the control of knee alignment-based knee osteoarthritis.
