Classification of periprosthetic fractures complicating total knee arthroplasty

As the total number of knee arthroplasties increase, the frequency with whi ch periprosthetic fractures will be encountered can be expected to increase as well. The classification of these fractures is an important aspect in t he development of an understanding of these problems. Adequate classificati on systems allow accurate communication between researchers and comparisons to be made between different techniques. Classification systems also allow algorithms to be developed to guide clinicians; in the diagnosis, investig ation, and treatment of these fractures. The authors present an outline of the classification systems described for fractures occurring in relation to total knee arthroplasty.
