New bone defect classification for revision total knee arthroplasty

A crucial factor determining the complexity of (revision TKA is the handling of bone defects. Various treatment strategies are available, depending on the location and severity of bone defects. To enable accurate pre-operative planning for revision TKA, accurate quantification of bone loss is necessary. Current bone defect classification systems are insufficient for revision TKA because bone loss in the metaphysis and diaphysis are not rated. We developed a new bone defect classification for revision TKA, and tested its reliability.
