Actinomycosis caused by Actinomyces spp. is a chronic, progressive, suppurative and granulomatous bacterial infection. The general sites of infection are the head and neck, thorax and abdomen. Primary actinomycosis infection both on the knee and the ankle is uncommon. We report a very rare case of actinomycosis of the knee and ankle joint that was diagnosed and successfully treated with surgical resection and long-term antibiotic therapy.
