[Is there any difference in joint position sense among different knee angles?].

OBJECTIVES: The purpose of this study was to analyse the knee joint position sense in different knee angles and to compare the results. PATIENTS AND METHODS: Forty healthy volunteers (20 females, 20 males; mean age 21.1 +/- 0.7; range 19 to 23 years) participated this study. The joint position sense was analyzed at 15, 30, 60 and 90 degrees of knee flexion using the motion analysis system designed by us. RESULTS: The highest error was observed at 60 degrees of knee flexion. Statistically significant differences were found between 15-30, 15-60, 30-90 and 60-90 degrees of knee flexion. No significant difference was observed between 15-90 and 30-60 degrees of knee flexion. CONCLUSION: It has been demonstrated that the measurements of knee joint position sense differ in different positions.
