ABSTRACT
Postoperative infections following spine surgery are usually attributable to bacterial organisms. Staphylococcus aureus is known to be the most common single pathogen leading to this infection, and the number of infections caused by methicillin-resistant Staphylococcus aureus is increasing. However, there is a paucity of literature addressing postoperative infection with Mycobacterium tuberculosis. We encountered a case of tuberculous spondylitis after spine surgery. A man had fever with low back pain three weeks after posterior interbody fusion with instrumentation for a herniated intervertebral disc at the L4-L5 level. He had been treated with antibiotics for an extended period of time under the impression that he had a bacterial infection, but his symptoms and laboratory data had not improved. Polymerase chain reaction for Mycobacterium tuberculosis turned out to be positive. The patient's symptoms finally improved when he was treated with antituberculosis medication.

Snapping syndrome has rarely been reported in the knee. A snapping knee mainly occurs in the case of a translation of the lateral meniscus or a lateral discoid meniscus. Other causes include biceps femoris tendon, semitendinosus iliotibial band, and popliteus tendon. We recently experienced a case of a snapping knee caused by the semitendinosus tendon passing over the medial tibial condyle as a result of trauma.
