📌 Femoral Periprosthetic Fractures
✅ Lewis and Rorabeck Classification:
- Type 1: Nondisplaced femoral fracture with intact prosthesis
- Type 2: Displaced femoral fracture with intact prosthesis
- Type 3: Displaced or nondisplaced fracture with loosening or failing of the prosthesis
✅ Risk Factors:
- Defects of the anterior femoral cortex from surgical notching
- Cystic lesions of degenerative or rheumatoid origin
- Osteolysis secondary to wear-related debris
✅ Supracondylar Fractures:
- Most frequently encountered fracture near a TKA (Total Knee Arthroplasty)
- Often, a devastating complication
- Classified and managed based on displacement and prosthesis stability
📌 Tibial Periprosthetic Fractures
✅ Felix and Stuart Classification:
- Type 1: Fractures involve the tibial plateau
- Type 2: Fractures are adjacent to the tibial stem
- Type 3: Fractures are distal to the prosthesis
- Type 4: Fractures involve the tibial tubercle
✅ Occurrence and Management:
- Tibial periprosthetic fractures occur infrequently
- Classified and managed based on the anatomic location of the fracture and the stability of the prosthesis
