title: The radiological assessment of total and unicompartmental knee replacements.
abstract: Radiological assessment of total and unicompartmental   knee replacement remains an essential part of routine care and follow-up.   Appreciation of the various measurements that can be identified   radiologically is important. It is likely that routine plain radiographs   will continue to be used, although there has been a trend towards   using newer technologies such as CT, especially in a failing knee,   where it provides more detailed information, albeit with a higher   radiation exposure. The purpose of this paper is to outline the radiological parameters   used to evaluate knee replacements, describe how these are measured   or classified, and review the current literature to determine their   efficacy where possible.
