Abstract

There are no reports of the occurrence of a cyst in the anteromedial side of the proximal tibia after cementless total knee arthroplasty in the Korean literature. The authors encountered 2 cases with a cyst, in whom the pain improved after cemented total knee revision arthroplasty. We report these cases with a review of the relevant literature.

  Fig. 1 (A) The CT image of a knee of a 71-year-old female showing a cyst communicating with the screw hole of the tibia component. (B) The varus and valgus stress radiography showing displacement of the tibial component suggesting possible loosening. (C) An egg-size cyst was excised. (D) The biopsy of the cyst shows a pseudocyst without endothelial lining (H-E, 40× magnification).

  Fig. 3 (A) Painless cyst in the anteromedial side of proximal tibia. (B) Simple radiographs of a 68-year-old female showing a radioluncent line on the femoral and tibial component suggesting possible osteolysis. (C) The CT image shows a cyst communicating with the tibial component. (D) Fistula was found between the upper joint line of the tibia and a cyst on the anteromedial side of the proximal tibia during surgery. Cement was used to fill the fistula.
