LIPUS attenuates cartilage degeneration in early osteoarthritis-like model mice. A Safranin O-stained histology sections of articular cartilage after weeks 1 and 4. The results were used to calculate the osteoarthritis research society international (OARSI) scores of all four quadrants of the joint: medial femoral condyle (MFC), medial tibial plateau (MTP), lateral femoral condyle (LFC), and lateral tibial plateau (LTP). Values are expressed as mean ± standard error of the mean (SEM), n = 4; * = p < 0.05. (Scale bar: 100 μm). B Collagen degeneration on the articular cartilage was detected with Denatured Collagen Detection Reagent (green). Type II collagen was immune-stained (red). (Scale bar: 100 μm)
