Clinical Trial Summary

The goal of this observational study is to describe the radiographic and kinematic features in patients with femoroacetabular impingement syndrome (FAI). The main questions it aims to answer are: - Is structural knee abnormalities associated with knee pain symptoms in FAI patients? - Does FAI patients with knee pain demonstrate unique kinematic characteristics？ Participants will receive routine preoperative radiographic examinations, which include ipsilateral knee MRI for the purpose of femoral version measurement. Participants will also receive markerless motion capture analysis. Researchers will compare preoperative radiographic and kinematic features based on knee pain status, which is routinely collected as part of clinical investigation procedures.

Description:

This observational study aims to study the association between preoperative subjective knee pain and baseline knee radiographic and kinematic characteristics. MRI of the ipsilateral knee is screened for structural abnormalities, including cartilage defects, meniscal tears and ligament injuries. Markerless motion capture data are evaluated for transverse plane kinematic features, with a primary focus on foot progression angles during normal gait.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Preoperative radiographic cartilage defect of ipsilateral knee	On the same day of admission, patients receive routine preoperative MRI examination of the hip and ipsilateral knee for femoral version measurement. Radiographs of ipsilateral knee MRI are evaluated for the presence of structural knee abnormality. Radiographic signs suggesting cartilage defect of the patella, femur and the tibial plateau are collected.	Knee MRI radiographs are evaluated at baseline.
Primary	Preoperative radiographic meniscal tear of ipsilateral knee	On the same day of admission, patients receive routine preoperative MRI examination of the hip and ipsilateral knee for femoral version measurement. Radiographs of ipsilateral knee MRI are evaluated for the presence of structural knee abnormality. Radiographic signs suggesting lateral or medial meniscal tears are collected.	Knee MRI radiographs are evaluated at baseline.
Primary	Preoperative radiographic ligament ruptures of ipsilateral knee	On the same day of admission, patients receive routine preoperative MRI examination of the hip and ipsilateral knee for femoral version measurement. Radiographs of ipsilateral knee MRI are evaluated for the presence of structural knee abnormality. Radiographic signs suggesting ACL tears, PCL tears or collateral ligament ruptures are collected.	Knee MRI radiographs are evaluated at baseline.
Primary	Foot progression angle during normal gait	The next day after admission, patients undergo markerless motion capture evaluation after informed consents are obtained. Movements for motion capture include normal gait, stepping in place, single-leg stance, double-leg squat and forward lunge. Each movement is repeated 2 times. The entire data collection process for each patient takes approximately 120 seconds. Foot progression angle during gait are assessed with MATLAB in a retrospective fashion after completion of patient recruitment.	Motion capture data are assessed at baseline.
