No results posted yet for this study

Summary

The study enrolled 33 patients with confirmed recurrent patellar dislocation, including 6 patients with bilateral involvement. In the study group, both side hamstring muscle were evaluated at the velocities of 60 and 180 deg/s for the following parameters: peak torque, torque in 30 degree of the knee flexion, angle of peak torque and peak torque hamstring to quadriceps ratio (H/Q ratio).

Conditions

  • Patella Dislocation Recurrent
  • Children, Only

Interventions

DIAGNOSTIC_TEST

Isokinetic measurements

Each patient underwent an isokinetic examination on Biodex System 3 (Biodex Multi-Joint System - Pro, Biodex Medical Systems, Inc. New York, USA). In the study group, both side hamstring muscle were evaluated at the velocities of 60 and180 deg/s for the following parameters: peak torque (PT), torque in 30 degree of the knee flexion (T 30 deg.), angle of peak torque (APT) and peak torque hamstring to quadriceps ratio (H/Q ratio).
