The meniscus is a C-shaped piece of cartilage that acts as a shock absorber between your thighbone (femur) and shinbone (tibia). Each knee has two menisci – one on the inner side (medial meniscus) and one on the outer side (lateral meniscus). A meniscus tear occurs when this cartilage is damaged through forceful twisting, sudden movements, or gradual degeneration. In Singapore, meniscus tears are among the most common knee injuries, affecting both young athletes and older adults. The meniscus plays a crucial role in knee stability, load distribution, and smooth joint movement, making prompt treatment essential for maintaining long-term knee health.
Radial tears extend from the inner edge of the meniscus outward, resembling a spoke on a wheel. These tears disrupt the circumferential fibres that give the meniscus its strength. They compromise the meniscus’s ability to distribute weight evenly across the knee joint.
