Study Overview

Brief Summary

All the data of patients with patellar dislocation will be collected to evaluate the anatomic deformities. The data includes X-ray, CT, MRI examinations, medical records, and physical examination information. Finally, we correlate the anatomic deformities with clinical efficacy. To search for the risk factors that lead to patellar dislocation and influence the therapeutic effect.

Outcomes

Primary Outcomes

International Knee Documentation Committee(IKDC) score

Time Frame: Three years after surgery

The entire IKDC form, which includes a demographic form, current health assessment form, subjective knee evaluation form, knee history form, surgical documentation form, and knee examination form, may be used as separate forms. The knee history form and surgical documentation form are provided for convenience. All researchers are required to complete the subjective knee evaluation and knee examination form. Instructions for scoring the subjective knee evaluation form and the knee examination form are provided on the back of the forms. Total score 100, ≥75 being considered excellent.

Number of participants with redislocation of their patella after surgery as confirmed by clinical physical examination

Time Frame: Three years after surgery

We can determine patellar redislocation by physical examination. In participants with redislocation of their patella, the patella (kneecap) slips out of its normal position. Often the knee is partly bent, painful and swollen.The patella is also often felt and seen out of place. We recored the number of participants with redislocation of their patella after surgery.

Magnatic Resonance Imaging evaluation

Time Frame: Three years after surgery

All patients undergoing anterior cruciate ligament reconstruction underwent MRI imaging evaluation of both knees. Use International Cartilage Repair Society(ICRS) score to evaluate, total score is 12, classified into four grades,grade Ⅰ: normal (12), grade Ⅱ: nearly normal (8-11), grade Ⅲ: abnormal (4-7), grade Ⅳ: severely abnormal (1-3).

Secondary Outcomes

  • Skeletal force line and various angles by X-ray evaluation(Preoperative)
