Assessment of Knee Flexor Muscles Strength in Patients With Patellar Instability

51 participantsStarted 2015-01-10

Plain-language 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).
