Description

To clarify the characteristics of the screw home movement, we performed 3-dimensional motion analysis using the point cluster method. Thirty healthy adults aged 20-65 years performed active knee extension in a non-weight bearing position. In 19 subjects, the tibias externally rotated during extension. In 5 subjects, the tibia started to rotate internally near the terminal range of motion. The other 6 subjects showed internal rotation of the tibia during extension. Most subjects showing rotation of the tibia at the terminal range of motion were female. All subjects with this finding showed positive results for the laxity test, and the amount of tibial anterior shift during extension was large. The subjects showing internal rotation of the tibia during extension were older than the other subjects. These results suggest that the screw home movement is affected by tension of the ligaments and age.<br>
