The RAMP
Knee Positioning System™
Completely unconstrained leg manipulation between all stabilized knee flexion positions (~55°, ~90°, ~115°, ~140°, ~150°*) allows for unrestricted soft tissue assessment and quick, easy dynamic registration for computer navigation. (*These angles are approximate. Exact angles depend on specific setup technique and vary from patient to patient.)
The RAMP is easily installed at the foot end of any standard OR table and below the sterile drape.
Knee Positioning
With the Misha Knee System

The RAMP can be used for knee positioning with systems like the Misha Knee System (Implantable Shock Absorber).
Features
Improved Surgical Ergonomics
During TKA, the position of the knee changes frequently between the two extreme positions of flexion and extension. The RAMP elevates the knee in full extension, reducing the total change in height of the surgical field during the procedure. The raised-foot design more easily enables full knee extension, especially for patients with larger thighs.
Optimized Pad Design
The flat, firm, proximal-facing pad surface provides stable positioning for the sole of the foot, while the soft, rounded distal side protects the Achilles tendon. The raised edges improve visibility of each pad location through the drape.

Hands-free Stability
Installing a lateral support and a wedge below the hip leads to maximum stability in all six leg positions with unobstructed access to the leg.
