Conversion of mgh hemiarthroplasty of the knee to total knee arthroplasty using custom tibial components.
Hemiarthroplasty of the knee, similar to that of the hip, is frequently accompanied by the late development of pain associated with erosion of the metallic implant through opposing cartilage and bone. The authors present two patients (3 cases) in which MGH condylar hemiarthroplasty of the knee was treated for this problem by the addition of custom tibial components rather than complete revision to a modern total knee replacement device. The method is presented not as a treatment of choice, but as an alternative to complete revision (requiring the removal of additional femoral bone stock and possibly the need for a more constrained device) which provided relief of symptoms without accelerated wear of prosthetic components in a small number of knees.
