Ruchholtz et al[9]	NA	NA	No patients, only offered treatment methods for various fracture classifications
Felix et al[10]	102	All types	Many different methods were used depending on the fracture type

Table 2 Breakdown of the types and subclass for diagnosing periprosthetic tibia fractures, as described by Felix et al[10] in her 1997 study

Type	Description	Subclass	Description
1	Partial tibial plateau	A	Stable prosthesis
2	Full tibial plateau	B	Unstable prosthesis
3	Distal tibial shaft	C	Intraoperatively
4	Tibial tuberosity

Table 3 Breakdown of the incidents of types and subclasses of fractures

Type	Incidents	Subclass	Incidents
1	62	A	27
2	24	B	63
3	24	C	54
4	2
Total	112	Total	144

The total number of patients in the review was 154, but not every patient was classified fully.
