Cartilage Repair:

Cartilage is the smooth articular surface where two bones meet inside a joint. It can be damaged through acute trauma, developmental abnormalities or chronic degeneration. Localized cartilage damage is referred to as focal defect, while more widespread, diffuse disease is termed osteoarthritis.

There are multiple options to address cartilage damage, ranging from various cartilage repair procedures for focal defects, all the way to partial and total knee replacement for widespread bone-one-bone osteoarthritis.

Osteotomy:

When legs are straight, the forces across the knee joint are evenly distributed. Occasionally, however, the alignment is off, either congenitally, due to trauma or degeneration. This so-called malalignment can increase the rate of further degeneration.

It can be addressed through osteotomy procedures, where the malaligned bone is cut and realigned, then held in place with a plate until it heals. The plate can later be removed in a simple outpatient procedure.
