Improved technique in extensor mechanism reconstruction, Mesh Graft in Extensor Mechanism Disruption

Video Description

Dr. Abdel reviewed the latest data on survivorship of the mesh graft in procedures done at Mayo Clinic.
Extensor mechanism disruption is a dramatic complication of total knee arthroplasty, often resulting in poor results of the procedure. It is typically treated with Achilles tendon allograft or whole extensor mechanism allograft, both of which have their pros and cons.

There is another option: synthetic mesh reconstruction. Popularized by Arlen D. Hanssen, MD, the synthetic mesh graft has become the preferred treatment option for extensor mechanism disruption at Mayo Clinic.

Matthew P. Abdel, MD, demonstrated the surgical technique he and his Mayo Clinic colleagues use for synthetic mesh reconstruction, noting this is a cost-effective option that avoids the limitations of allograft use and, with experience, is an efficient surgical technique that can be executed in a systematic manner.

During his presentation, Dr. Abdel reviewed:

Graft preparation
Tibial trough preparation
Insertion of the mesh and lag screw
Distal and proximal incorporation of the graft
Creation of a unitized lateral/mesh base
Closure by the pants-over-vest technique to cover the entire mesh
