Right knee joint CT: Slightly irregular cortical bone at the lower pole of the right patella 【Disease Course and Treatment Outcome】: After admission, relevant examinations were completed. The left lower limb was immobilized with a patellar brace. The original plan was elective left knee arthroscopy exploration + medial patellofemoral ligament reconstruction. The patient requested discharge against medical advice. With approval from the attending physician, she was discharged this afternoon. 【Complications】: None 【Main Symptoms and Signs at Discharge】: The patient was alert and in fair spirits, complaining of left knee pain. Physical examination: Vital signs stable, left knee immobilized with patellar brace, left knee swelling, tenderness (+), no sensory deficit in the left lower limb, strong dorsal pedal artery pulsation, good distal blood supply to the toes, normal toe movement. 【Post-Discharge Medications and Recommendations】: 1. Recommend further treatment at another hospital's orthopedics or sports medicine department; 2. Follow-up in orthopedic outpatient clinic. 【Treatment Outcome】: Discharge against medical advice Date: December 13


The above discharge summary from Hospital A clearly states, "The original plan was elective left knee arthroscopy exploration + medial patellofemoral ligament reconstruction. The patient requested discharge against medical advice." However, the girl's parents said they decided to leave because Hospital A recommended surgery on both legs. The following is the left knee joint X-ray report from Hospital B Department: Orthopedics and Traumatology Examination Date: January 7 of the following year, 08:29:04 Report Date: January 7 of the following year Clinical Diagnosis: Follow-up Examination Name: Left knee joint AP and lateral views Examination Method: DR Radiological Findings: Avulsion fracture of the intercondylar eminence of the left tibial plateau, with the fracture fragment now showing mild medial tilt. Mild soft tissue swelling at the lateral supracondylar region of the femur. No abnormalities in the remaining bones. Joint is in position with normal joint space. Radiological Diagnosis: Avulsion fracture of the intercondylar eminence of the left tibial plateau, with the fracture fragment now showing mild medial tilt. Mild soft tissue swelling at the lateral supracondylar region of the femur.


* The following is the knee joint CT plain scan + reconstruction report from Hospital C Department: Orthopedics, Arthroscopy Specialty Examination Category: CT examination Referring Physician's Request: Confirm diagnosis Clinical Diagnosis: Trauma Examination Site and Name: Left knee CT plain scan (3D) Examination Method: Left knee transverse CT plain scan + 3D reconstruction Imaging Findings: Small bone fragment shadow at the posterior margin of the left patella, strip-like high-density shadow in the joint cavity, small amount of effusion in the left knee joint, small depression in the lateral condyle of the left femur, shallow femoral trochlea on the left, no obvious bony abnormalities in the remaining bones of the left knee joint, joint in position, smooth articular surfaces, no obvious narrowing of the joint space. Imaging Diagnosis: Shallow left femoral trochlea, possible left patellar dislocation with post-reduction changes, small avulsion fracture of the left patella, small amount of effusion in the left knee joint. Please correlate with clinical findings and follow up. Examination Time: January 10 of the following year, 09:52:00 Report Time: January 10 of the following year, 10:03:51 Film Review Time: January 10 of the following year, 16:28:14


The girl, accompanied by her parents, visited the outpatient clinic at Hospital C four times. Three visits occurred on December 27 with one doctor, and on January 17 of the following year with two different doctors on the same day. One additional outpatient record did not specify the visit date. During the four outpatient visits at Hospital C, some doctors recommended conservative treatment, some suggested deciding on surgery based on the situation, and some advised immediate surgery. However, none of the four doctors mentioned the tibial intercondylar eminence fracture. They also did not clearly state whether the surgery would target the left knee or both legs. Some doctors did document in writing the congenital shallow femoral trochlea.
