Brief 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.

Group/Cohort Intervention/treatment
Group primary TKA
Patients operated of primary TKA Stryker for knee osteoarthritis.
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).

Other Name: Total knee arthroplasty

Group TKA revision
Patients operated of a first revision of TKA for a mechanical failure, with the revision Stryker TKA
Device: Group TKA revision

Primary Outcome Measures :
  1. Femorotibial mechanical axis (varus, valgus) analysis [ Time Frame: at 6 months postoperatively ]
    These parameters are measured with the KneeKG system during the walking

  2. range of motion (flexion, extension) analysis [ Time Frame: at 6 months postoperatively ]
    These parameters are measured with the KneeKG system during the walking

  3. internal/external rotation analysis [ Time Frame: at 6 months postoperatively ]
    These parameter is measured with the KneeKG system during the walking

  4. Walking speed [ Time Frame: at 6 months postoperatively ]
    These parameter is measured with the KneeKG system
