Analysis of radiographic factors affecting the significant differences in knee alignment between hip-to-talus and hip-to-calcaneus radiographs after opening-wedge high tibial osteotomy.

Background: Optimal alignment after opening-wedge high tibial osteotomy (OWHTO) is crucial for obtaining good clinical results. A hip-to-calcaneus radiograph (HCR) appears to reflect the true mechanical axis. However, no study has been reported using the HCR in patients who underwent OWHTO.

Effectiveness of paraffin bath therapy for the symptoms and function of hand diseases: A systematic review and meta-analysis of randomized controlled trials.

Background: Paraffin bath therapy is noninvasive and is widely used in various hand diseases. Paraffin bath therapy is easy to use, has fewer side effects, and can be applied to various diseases with different etiologies.
