Surgical outcomes of subtypes of periprosthetic tibia fractures after total knee arthroplasty.

Surgical outcomes of subtypes of periprosthetic tibia fractures after total knee arthroplasty were evaluated by using the Felix et al. classification system. Type 3 fractures were the most common classification of periprosthetic tibial fractures. Type 2 fractures had the highest rates of revision and nonunion. Type 3 fractures exhibited longer healing times than types 2 and 4. Far type 3 fractures showed the longest healing time of all fracture types but had very minimal complications. Type 4 fracture managed by K-wire/cerclage wire may require hardware removal or debridement but exhibited the shortest healing time compared to types 2 and 3.
