Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group primary TKA
Patients operated of primary TKA Stryker for knee osteoarthritis.
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).
Group TKA revision
Patients operated of a first revision of TKA for a mechanical failure, with the revision Stryker TKA
Group TKA revision
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 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).
