lospa knee

Stem Housing Angle: 6°

The modular femoral component has a stem housing that is tilted 6° laterally.

Stem Housing Position: 35% from Anterior

Constrained Motion

2° at knee extension

4° at 75° flexion

Tibial Component

Concaved Post Design

The posterior part of the post is concavely curved. After cam-post engagement at 75 degrees of flexion, the cam travels down the post. This reduces the risk of the dislocation and allows for deep flexion with joint stability.

Heightened Post

For better stability during the entire knee motion, the post height is designed higher than the Lospa Primary Knee System.

Augment

Lospa Modular Knee System has two types of the Augment: Block and Choren Pad

Block

Complementing bone deficits
Thickness: 5, 10, 15mm
Bolt/Cement fixation
