Precision Hip & KneeReconstruction
Most patients need a straightforward joint replacement. Some require something more. Every patient deserves thoughtful planning, meticulous execution, and a surgeon focused on restoring function—not simply performing a procedure.

A Different Philosophy
From your first joint replacement to the most complex reconstruction.
The operation should fit the patient and the diagnosis—not the other way around. Revision expertise informs primary care, and every decision begins with establishing the source of the problem.

Request a consultation →Why the Mayo Approach?
A distinctive hip replacement approach built for routine and complex reconstruction.
Dr. Behrens uses the Mayo Modified Anterolateral Approach for primary and revision hip replacement. It provides access from the front and side of the hip, does not require a specialized traction table, and can be expanded when complex reconstruction requires greater exposure.
Explore the Mayo ApproachStabilityPreserves posterior structures that contribute to hip stability.
VersatilityUsed across straightforward primary and complex revision cases.
Extensile ExposureCan be expanded when implant removal or additional reconstruction is required.
No Specialized TablePerformed without dependence on a traction-table workflow.
