Can you describe the pathophysiology of a total knee replacement, please?

TKA: I'm not sure exactly what you mean. But a tka is a resurfacing procedure that removes irregular surfaces and corrects angular and rotatory deformities by using a modular, specifically measured and fit tibial, femoral, and patellar components. This helps regain normal knee biomechanics of flexion, extension, rotation, and roll.

Resurfacing the knee: A total knee replacement involves removal of a few millimeters of bone and cartilage from the bones that rub together in the knee. The area of bone removal is then resurfaced with metal and plastic material to provide artificial surfaces that rub together. This is similar to what a dentist does when capping a tooth. It then provides a painfree articulation. Rehabilitation restores motion.
