: This study aims to clarify the reproducibility, validity, and accuracy of tibial external-rotation alignment evaluation using ultrasound imaging and to investigate the relationship between medial meniscus extrusion (MME) and tibiofemoral alignment in both the sagittal and coronal planes in knee osteoarthritis (OA). : Study 1 included 10 healthy participants. The tibial external-rotation angle was calculated using MRI.

- The study investigates the relationship between the thickness of the inferior glenohumeral joint capsule (IGC) and range of motion (ROM) in patients with frozen shoulders compared to healthy individuals.
- It involved 29 frozen shoulder patients and 20 healthy shoulders, measuring IGC thickness using ultrasound at three levels while assessing ROM.
- Findings revealed that IGC thickness was greater in frozen shoulders, with significant negative correlations between thickness at the parenchymal level and various ROMs, suggesting that this measurement can help guide treatment options.
Background: Ulnar collateral ligament (UCL) and flexor-pronator muscle (FPM) injuries are common in baseball players. However, the sites of FPM injuries and the relationship between UCL and FPM injuries in baseball players have not been fully clarified. The purpose of this study was to identify the sites of FPM injuries and to determine the relationships of location and severity of UCL injury with the presence of FPM injuries in baseball players.
