Details and patient eligibility

About

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.
