Abstract：Objective To investigate the clinical features and differential diagnosis of knee tuberculosis, in order to re-duce the incidence rate of misdiagnosis. Methods The clinical data of 6 tuberculosis patients being initially misdiagnosed as having pigmented villonodular synovitis were analyzed retrospectively. Results All the patients misdiagnosed as having pigmen-ted villonodular synovitis complained of knee pain, swelling and limited mobility. Of the 6 cases of synovial tuberculosis, 2 cases were of primary, 4 cases were of recurrence with misdiagnosis history in other hospitals. 5 cases received combined synovectomy of both the front and the rear approach; one case received single synovectomy of the rear approach. The clinical, imaging and pathological data confirmed the final diagnosis of synovial tuberculosis. All the misdiagnosed patients underwent postoperative an-tituberculous therapy and obtained good improvement and rehabilitation of knee function. Conclusion The features of synovial tuberculosis are not typical and the misdiagnosis can be easily made. To avoid misdiagnosis,it is essential to have a detailed medical history, complete relevant examination data and the differential diagnosis of knee tuberculosis.
