Researchers suggest that human knee problems, particularly osteoarthritis, may be a consequence of evolutionary changes. While humans excel in many areas compared to chimpanzees, our knees haven’t benefited from the same advancements. The shift to bipedalism, or walking upright, placed new stresses on the knee joint, contributing to a higher incidence of issues. This transition, while crucial for human development, didn’t come without physical costs. Specifically, the altered biomechanics increased the load on the medial compartment of the knee, making it prone to wear and tear. This evolutionary trade-off explains why humans are so susceptible to knee pain and osteoarthritis compared to our primate relatives.
