Background: Periprosthetic knee fracture (PPKF) following total knee arthroplasty (TKA) can be difficult to treat. A PPKF can be treated both operatively and nonoperatively, and the treatment varies between fracture sites. This study aimed to assess the risk of reoperation according to the fracture site and treatment of the PPKF.

- Periprosthetic knee fractures (PPKFs) after total knee arthroplasty (TKA) are rare but serious, and this study examines risk factors in patients with osteoarthritis and varying levels of implant constraints.
- The analysis included data from over 120,000 primary TKA patients in Denmark, revealing that the cumulative risk of PPKFs increases over time, with notable risk factors being age, gender, comorbidities, and prior hip surgeries.
- Among patients with additional knee disorders or high implant constraints, the risk of PPKFs at 10 years was significantly higher, particularly noted for those with previous fractures or osteonecrosis.
