Abstract
Surgeons managing these fractures must be aware of their complexity, and should always have alternative treatment strategies available in the operating room if the initially planned treatment cannot be performed.
Factors that must be considered to determine the proper treatment plan for each patient include:
- Geometry, displacement, and location of the that periprosthetic fracture.
- Component design.
- Evidence of component loosening.
- Patient’s prefracture ambulatory and general health status.
Stability of knee implant fixation is a key factor in selection of treatment strategy and stability should be determined preoperatively .
Treatment of periprosthetic fractures around the knee can be challenging as:
(1) Compromised fixation. by poor bony.stock.
(2) retarded healing power in elderly.
(3) The attachment of the ligamentous structures to the fracture fragment may predispose these knees to potential instability.
The goals of treatment, whether surgical or nonsurgical, are fracture healing, restoration and maintenance of knee range of motion, and pain-free function.
A good result is a minimum of 90 Degrees of knee motion, fracture shortening less than 2 Centimeters, varus/valgus malalignment less than 5 Degrees , and flexion/extension malalignment less than 10 Degrees .
These criteria, however, do not completely assess function, which is the most important to the patient.
