[Pseudothrombophlebitis, a rare complication following total replacement of the knee joint (author's transl)].
Pseudothrombophlebitis secondary to rupture of a Baker's cyst had been described repeatedly in the literature of rheumatology. If this condition is mistaken for deep venous thrombosis and treated with anticoagulation, serious complication may result, like hematoma of the lower legs or retroperitoneal and gastrointestinal bleeding. The case demonstrated here shows that this condition is not limited to patients with chronic rheumatoid polyarthritis. Qur patient with an endoprosthesis of the knee suffered from marked reaction to metal (= metallosis) in addition to malacia patellae. The resulting severe synovitis was the cause for pseudothrombophlebitis. Therefore, in cases of suspected venous thrombosis in combination with gonarthritis, and arthrogram of the knee joint or a cystogram should be obtained in order to exclude the possibility of pseudothrombophlebitis.
