title: Posterior leg sepsis associated with pyogenic arthritis of the knee. A report of two cases.
abstract: The association of posterior leg sepsis with pyogenic arthritis of the knee is rare, but nevertheless the diagnosis should be kept in mind. Calf swelling and tenderness with apparent antibiotic resistance in pyogenic arthritis of the knee are the major signs of the diagnosis. Ultrasound, computerized axial tomography, or aspiration of the posterior compartment may show fluid in the posterior compartment. Clinical examination is the most dependable method of diagnosis. Treatment consists of adequate surgical drainage of the posterior compartment and appropriate antibiotic therapy.
