Outcome Measures

Primary Outcomes (4)

knee biomechanics during single leg hop landing
knee kinematics(peak knee flexion, knee valgus, knee internal rotation, knee flexion excursion, valgus excursion and internal excursion) and kinetics(vertical ground reaction force, knee extension moment, knee valgus moment) were collected by 3D motion analysis system(VICON) during the landing phase of single leg hop test
post-operatively 6-18 months
muscle strength
muscle peak torque of knee extension and knee flexion at 60°/s and 180°/s tested with isokinetic mode by Biodex
post-operatively 6-18 months
muscle elasticity
muscle shear elastic modulus of vastus medialis, rectus femoris, vastus lateralis, semimembranosus,semitendinosus and biceps femoris was measured by ultrasound shear wave elastography
post-operatively 6-18 months
muscle coordination
muscle activity level and onset time of vastus medialis, vastus lateralis, semimembranosus,and biceps femoris was assessed by electromyography(EMG) during the landing phase of single leg hop test
post-operatively 6-18 months

Secondary Outcomes (3)

knee laxity
post-operatively 6-18 months
subjective knee function
post-operatively 6-18 months
Psychological readiness for return-to-play
post-operatively 6-18 months
