James A. Browne, MD, discussed treatment options for extensor mechanism disruption following total knee arthroplasty and factors that may lead to failure. He said the mainstays of extensor mechanism reconstruction include whole extensor allograft, Achilles allograft and synthetic mesh, all of which can be successful, but have an expected failure rate given the difficulty of this problem.

“The synthetic mesh procedure is my procedure of choice,” Browne said at a meeting. “It is technically simple, cost-effective, it avoids some of the concerns with allograft and I think the mid-term results are reasonable.”
