A 63 year-old male with a history of left knee replacement c/o left knee pain after fall.  He asks whether or not he will need the arthroplasty redone.  (Scroll down for answer)

Answer:  No

• Diagnosis: is a comminuted, periprosthetic distal left femur fracture
• Will not require revision if the implant is not loosened, there is sufficient bone for osteosynthesis, and he is not osteopenic
• Periprosthetic fractures require consultation with orthopedics, admission for evaluation and likely surgery.
• May need stabilization with intramedullary nail or locking plate prior to definitive management
