Knee Arthroplasty News and Research

RSS

Knee arthroplasty or knee replacement surgery has developed to its present advanced stage over the last few decades. This is mainly due to technical advances and better understanding of knee pathophysiology and functions.

Coral-inspired scaffold enhances bone repair by reprogramming immune cells

SONFH is one of the leading causes of non-traumatic osteonecrosis. Reported in up to 9%–40% of patients receiving prolonged or high-dose glucocorticoid therapy, the condition progressively weakens the femoral head and can eventually lead to joint collapse, making effective bone repair a major clinical challenge.
