Background: Various conservative treatments have been reported for refractory calcific tendinitis of the shoulder. This study aimed to evaluate the clinical outcomes of a combined therapy of focused shock wave (FSW) and ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT).
Methods: A total of 229 patients (246 shoulders) who experienced shoulder pain for over six months due to calcific tendinitis were included.
Purpose: The purpose of this study was to evaluate the integrity of the repaired rotator cuff between 1 and 2 years postoperatively after arthroscopic rotator cuff repair (ARCR) using magnetic resonance imaging (MRI), investigate the factors affecting its change, and assess the association between the change and postoperative clinical outcomes.
Methods: Rotator cuff tear patients who underwent ARCR and were evaluated by MRI before surgery, and 1 and 2 years after ARCR with a minimum of 2-year follow-up were included in this study. Repair integrity was evaluated using Sugaya's classification, and according to the classification types IV and V were defined as retears.
Glucocorticoid-induced osteoporosis (GIOP) lacks fully effective treatments. This study investigated the role of Piezo1, a mechanosensitive ion channel component 1, in GIOP. We found reduced Piezo1 expression in cortical bone osteocytes from patients with GIOP and a GIOP mouse model.

However, no reports have investigated the stability of UCL reconstruction with SA across multiple elbow flexion angles and the influence of SA on the stability and failure strength of the anchor and bone tunnel methods. This study aimed to compare the displacement against a valgus load at multiple elbow flexion angles of the anchor and bone tunnel methods between with and without SA, and to compare the failure strength between these methods with SA.

- MRI is commonly used to diagnose lateral epicondylitis (LE), but this study investigates whether MRI findings truly correlate with clinical symptoms in LE patients.
- Out of 243 patients with LE, high signal intensity changes were observed in a majority of elbows, yet results showed no significant correlation between these MRI findings and patients' symptoms.
- The study concludes that while MRI detects various changes in the extensor carpi radialis brevis and synovial folds, these findings do not predict or relate to the clinical condition of the patients.
