Brief Summary

Patellar tendinopathy (PT) is an overuse injury associated with loading activities, and popular among basketball and volleyball players. Although altered biomechanical characteristics during landing has been suggested as one of the risk factors for the development of PT, previous evidence failed to show the link between the sagittal plane biomechanics of the hip and knee joint and PT; and little was known about the frontal and horizontal plane biomechanics in athletes with PT. While other factors such as motor control or muscle activation also have not been explored fully. The purpose of this study is to compare hip motor control and biomechanical characteristics of the hip and knee joint during landing in athletes with and without symptomatic PT.

Outcome Measures

Primary Outcomes (5)

• Hip Flexion Angles

  Measure the hip joint angle when the knee reaches the maximum flexion angle during the landing phase of the countermovement jump

  In the experiment, the maximum knee flexion during the landing phase of the countermovement jump

• Maximal Knee Flexion Angle

  In the countermovement jump test, the force received by the force plate changes from 0 to a positive value during the landing phase. Measure the maximal knee flexion angle during this phase.

  The landing phase of the countermovement jump in the experiment

• Hip Abduction Angle

  Measure the hip abduction angle when the knee reaches the maximum flexion angle during the landing phase of the countermovement jump

  In the experiment, the maximum knee flexion during the landing phase of the countermovement jump

• Knee Joint Flexion Angle

  Perform the step-down test on a 15 cm high table to measure the knee flexion angle of the foot on the table when the side foot is at the lowest point.

  the contralateral foot is at its lowest point in step-down test in the experiment

• Motor Control Ability

  Having 4 motor control tests: Hip Flexion Control: Maintain an upright posture in a single-leg small knee bend. The knee aligns with the 2nd toe in the sagittal plane and \>5 cm beyond the toes. Internal/External Rotation Control:Perform a single-leg small knee bend while rotating the pelvis and upper body toward the opposite/same side. Rotate 35°/30° without excessive L/E compensation. Hip Adduction Control:Maintain a single-leg stance with symmetrical shoulders and pelvis. Pelvic lateral displacement \<10 cm, left-right displacement difference \<2 cm. Scoring Criteria: Avoid uncontrolled movements, perform isolated movements correctly, achieve adequate ROM, maintain normal breathing, control movements in eccentric/concentric phases, execute smoothly, stay relaxed and aware, ensure fluid transitions, avoid compensations, complete without feedback/support, and show no fatigue. Total score range: 0-52, converted to a percentage for comparison(0-100%).

  during the experiment, up to 4 hours
