Lyme arthritis most commonly affects which joint?

Explanation:
Lyme arthritis tends to involve large joints, with the knee being the most commonly affected. After Borrelia burgdorferi disseminates to the synovium, it triggers inflammatory monoarthritis that commonly presents as a swollen, painful knee with effusion. While other joints such as the ankle, wrist, or shoulder can also be involved, the knee is the classic and most frequent site, especially in later stages of the infection.
