Brief 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 degs 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 HQ ratio
Detailed Description:
The study enrolled 33 patients with confirmed recurrent patellar dislocation including 6 patients with bilateral involvement The study group consisted of 20 girls and 13 boys with average age at the time of the study 162 years range 8 to 17 years SD 27 For the purpose of the study a control group of 18 healthy subjects 12 girls and 6 boys aged on the average 157 years range13 to 17 years SD 15 was recruited
The following study inclusion criteria were applied recurrent patellar dislocation correctly completed testing protocol age under 18 years at the time of testing Subjects with osteochondral fracture and those with a history of the knee surgery were excluded
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 degs 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 HQ ratio
Isokinetic measurements were made by a trained experienced physiotherapist After a proper warm-up and instruction the test performed 10 full repetitions the best result was recorded The results of the peak torque PT of both test and control limbs were then compared with the normative data for age and gender available in the literature In addition we compared the peak torque PT torque in 30 degrees of the knee flexion T 30 deg angle of peak torque APT and peak torque hamstring to quadriceps ratio HQ ratio of involved and uninvolved knee flexor strength in the study group Depending on the data distribution the nonparametric Wilcoxons test or the parametric t-test for the related data was applied Statistical significance was assumed for p005 The study was approved by our Institutional Review Board Informed consent was obtained and the rights of subjects were protected
