Well, you go through pretty much the same thought processes that you went through for a solitary lesion. This is especially true in the distal femur and proximal tibia, which are the fastest growing metaphyseal areas in the skeleton. Radiographic criteria for loosening include wide or progressively enlarging radiolucency at the cement-bone, metal-cement, or metal-bone interface; component migration or subsidence; and cement fractures [25]. They are classified and managed according to the anatomic location of the fracture in reference to the tibial component and whether the prosthesis is stable or unstable [49] (Figs.

The incidence of patellofemoral complications after TKA has been reported as 210% [50]. On radiographs, metallosis appears as metal density in the distribution of the synovium [41]. FIGURE. The metaphysis also has the best blood supply of the bone, so entities such as infection or metastasis will commonly be seen in this area as well. sharing sensitive information, make sure youre on a federal Treatment options include prosthetic retention with thorough dbridement and polyethylene liner exchange, primary prosthetic exchange, delayed two-stage prosthetic exchange, and salvage procedures, such as resection arthroplasty, arthrodesis, and amputation.

The diagnostic workup for infection begins with two nonspecific blood markers of inflammation: erythrocyte sedimentation rate and C-reactive protein concentration [17]. Simple cyst, enchondroma, and fibrous dysplasia can mimic each other and can be hard to distinguish. Volumetric wear is a specific type of adhesive wear, and it occurs as the femoral head articulates with the cup liner, and the amount of wear is proportional to the femoral head radius squared (therefore larger femoral head = more wear..this is why the initial Charnley implants, which used conventional poly, used a size 22 femoral head).
