Current surgical techniques and tools do not present straightforward methods to remove excess bone cement from the posterior aspects of the femoral and tibial condyles during total knee arthroplasty. This leads to a detrimental amount of bone cement during application within the knee, causing an increased risk for premature knee failure, infection, or other complications. The goal of this project is to create a means to acquire improved access to posterior spaces for cement removal.
