Although the white blood-cell (WBC) count is often used as a marker for MSKI, we hypothesized that the use of the WBC count is limited by age-related variability in children. We proposed that the absolute neutrophil-to-lymphocyte ratio (NLR), which has less age-related variability, is a more reliable indicator for both diagnosing and assessing the severity of MSKI. The present study aims to compare the utility of WBC against that of the NLR, as well as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), for predicting MSKI presence and severity in children.</p><p><strong>Methods: </strong>A retrospective cohort study was conducted with use of a database of pediatric orthopaedic consultations for suspected MSKI between January 2013 and July 2022.

However, misplacement of the femoral tunnel remains a major problem that leads to revision after surgery for patellar instability. The C-arm technique for identifying the femoral origin of the MPFL (fMPFL) during surgery may not account for individual variability. Magnetic resonance imaging (MRI) allows for personalized fMPFL identification. The CLASS (Compressed Lateral and Anteroposterior Anatomical Systematic Sequences) method compresses MRI data into a lateral view, similar to intraoperative C-arm imaging.
