Tuberculosis (TB) is no longer confined to undeveloped or developing nations. Today, one third of world’s population suffers from tuberculosis. Tuberculosis (TB) of the musculoskeletal system is an uncommon infection caused by tuberculous bacilli and constitutes 1%-5% of all forms of TB. 30% of skeletal TB involves the joints, the knee being the third most commonly affected after the spine and the hip. Knee tuberculosis commonly presents as synovitis or arthritis. Baker’s cyst is a rather rare complication of knee joint tuberculosis. We report a case of a 50-year-old man with tuberculous arthritis of the right knee who presented to us as baker’s cyst.
