Abstract:

Post-traumatic osteoarthritis is a degenerative joint disease following trauma, mainly characterized by the abnormal regulation of chondrocytes cartilage degeneration. The pathogenesis of post-traumatic osteoarthritis is the result of biomechanics and cell biology, but the key mechanism is unclear.Studies have shown that mechanical sensitive protein Piezo1, as a mechanical receptor, converts mechanical - electrochemical signals by sensing cell membrane mechanical stimulation, which is closely related to the pathological occurrence and progression of post-traumatic osteoarthritis.This review showed the related studies on the mechanism of Piezo1-mediated post-traumatic osteoarthritis and discusses the possibility of Piezo1 as an intervention target for post-traumatic osteoarthritis in the future.

Key words: Osteoarthritis, Chondrocytes, Ion channels, Stress, mechanical
