A periprosthetic fracture occurring around a total knee replacement involving the femoral condyle distal to a well-fixed femoral component is classified as:
- A Vancouver Type C
- B Rorabeck Type I
- C Su Classification Type I ✓
- D Lewis and Rorabeck Type III
Correct answer: C. Su Classification Type I
Explanation
The Su classification is used for periprosthetic fractures around total knee arthroplasty. Type I fractures occur proximal to the femoral component and are essentially supracondylar fractures. Type II involve the component level. Type III are distal to the component. Vancouver classification applies to periprosthetic hip fractures, not knee.
