The use of double abdominal braces in knee replacement

BacKGRoUnD The correct cementing technique for knee replacement involves maintaining the knee in extension for a protracted period of time to compress the cement effectively during polymerisation.1,2 Wound closure can be completed in flexion or extension with no difference in functional outcome3 but is often also completed with the leg maintained in extension due to decreased tissue tension. With the increasing average mass of patients, holding a leg in extension can often involve significant energy expenditure. We report an effortless, efficient technique for holding the knee in extension for an indefinite period without the need for surgeon or assistant exertion.
