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.
Interventions
OTHERCollect the clinical data
We analyze the influence of the anatomic deformity on the clinical efficacy at the follow-up.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with redislocation of their patella after surgery as confirmed by clinical physical examination | 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. |
| International Knee Documentation Committee(IKDC) score | 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. |
| Magnatic Resonance Imaging evaluation | 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
| Measure | Time frame | Description |
|---|---|---|
| Skeletal force line and various angles by X-ray evaluation | Preoperative | X-ray was used to evaluate the skeletal force line and various angles of patients. Use Qvadriceps Angle to evaluate quadriceps force line and patellar ligament force line. The normal Angle is 18-22° for the adult standing position.Above or below this range is considered abnormal. |
