Tuberculous osteomyelitis of the knee

Abstract

Tuberculosis is a mycobacterial infestation which generally involves the lungs. Primary bone tuberculosis without involving the joint is rare. A 35-year-old Pakistani immigrant presented with a mass and pain over the medial aspect of the knee that had persisted for 6 months. Clinical and radiological investigations revealed a tuberculous affectation of the distal epiphysis of the femur. We did not find any visceral organ involvement. Wide excision was performed, completed with antituberculostatic drugs for 9 months postoperatively. In the 2nd postoperative year, the patient was symptom-free, and the imaging test results were normal. Primary bone tuberculosis without joint affection is a rare presentation form of this disease and should be kept in mind in the diagnostic work-up of a mass of a bone lesion.

Tuberculous Arthritis of Knee Presenting as Bakers Cyst: A Case Report

“…Musculoskeletal involvement is through haematogenous spread often from a primary focus frequently the lungs as in this case. The incidence of skeletal TB is increasing due to the emergence of multi-drug resistant mycobacterium, increase in the number of immuno-compromised patients and the AIDS pandemic [4]. Although no age is exempted its incidence in elderly and debilitated patients is high.…”

“…Early radiological findings are nonspecific and can't be differentiated from non specific arthritis. The relative preservation of joint space which is a classical feature is due to the lack of proteolytic enzymes in Mycobacterium tuberculosis [4].…”

“…Early metaphysical involvement, synovial thickening and articular changes are better demonstrated on MRI which has now become the mainstay of imaging in musculoskeletal tuberculosis [4] [9]. MRI and computerized tomography also help in outlining the baker's cyst and its contents when present; they also help in assessing rupture of the cyst [5] [8].…”

Tri-compartmental tubercular arthritis of knee masquerading as popliteal fossa tumor: a case report

“…Isolated involvement of the patella has also been reported in some published articles [2][3][4][5] . A wedge shaped area of sequestrum formation involving both sides of the involved joint (kissing sequestra) has also been described 6,7 .…”

Concomitant cutaneous metastatic tuberculous abscesses and multifocal skeletal tuberculosis

“…Skeletal tuberculosis accounts for 10-15% of cases of extrapulmonary tuberculosis 151718. Recently, the proportion of bone or joint tuberculosis has progressively increased to 27% 19.…”
