Gait Kinematics After Primary Total Knee Arthroplasty (TKA) Versus Revision TKA

Assessment at Short Term of the Gait Kinematics After Primary TKA (Stryker) Versus After Revision TKA. Prospective and Controlled Study.

Summary

The functional outcomes after TKA are satisfying with a full recovery at 6 months - 1 year. Nevertheless, the revisions of TKA have often lower functional results than primary TKA with a long delay of recovery. The Stryker TKA present the same device for primary TKA and for revision. The aim of this study is to compare the gait kinematics at 6 months after primary Stryker TKA or Revision Stryker TKA to assess if the objective outcomes are similar with this device.

Conditions

• Knee Arthroplasty, Total
• Gait Analysis

Interventions

Type	Name	Description
DEVICE	Group primary TKA	Assessment by gait kinematics analysis The total knee arthroplasty will be performed as usual with the dedicated instrumentation. The gait kinematics analysis will be performed with the KneeKG system on a treadmill, with infrared sensors (IR) on the leg. This system is not invasive. The IR sensors are positioned on the pelvis, the distal femur and the tibial crest. This system records the flexion/extension, the varus/valgus and the rotation during the walking (1 minute of walking).
