[Synovial chondromatosis and tuberculosis of the hip coexistence].

This article describes a rare case of primary synovial chondromatosis of the hip associated with active tuberculosis of the hip. Twenty four years old patient underwent total hip replacement at our institution. No reactivation of the infection was detected in the four-years follow-up.

Radiographic evaluation of the results of total hip arthroplasty with the cementless Zweymüller endoprosthesis.
