Abstract:
The knee joint is the largest joint in body and structurally most complicated. Although it is generally considered to be modified hinge joint. Which permits very free flexion and extension. It is complex and involve gliding and rotation of free leg. Since data are not available about the range of medial and lateral rotation of tibia. This study was proposed to find out the range of medial and lateral rotation and tibia affected actively by person of different age groups and also to find out any differences which can be attributed to handedness, profession and sex of the individual. The study was conducted on boys and girls subjects of two different age group, first group was 10-17 years aged school going students and second group was 18-25 years aged college students. These subjects are from different cast and races forming the local population. The subjects were selected only after confirming that there was no involvement of knee joint by any disease. The range of lateral, medial and total rotation of tibia in school going students is significantly higher than the college going students. All the tibial rotation are found to be slightly higher in girls than the boys in both groups. Since at 10-17 years the growth and development of bones is not yet complete and the structure of knee joint has reached its adults configurations therefore these values may be taken as temporary.
