Brief summary
The study consists to evaluate the impact of prosthetic surgery (PTH and RTH) on kinematic and dynamic parameters (joint torques) of the lower limbs during gait initiation in patients with primary coxarthrosis. Patients included in the study will undergo a three-dimensional gait analysis. Dynamic gait analysis is multidimensional, measuring kinematic parameters (joint amplitudes: ankles, knees, hips, etc.) and dynamic parameters (assessment of joint torque from ankle, knee, hip to lower limb during gait initiation).
Interventions
OTHERPatients with primary coxarthrosis (any stage).
Patients who do not undergo surgery will be called specifically for the study to attend a consultation dedicated to gait assessment.
OTHERPatients with primary coxarthrosis (any stage) and operated with Total Hip Prosthesis (THP).
Patients scheduled for THP (Total Hip Prosthesis) will be seen at the consultation the day before surgery, in the same hospital as the THP, or at an existing dedicated consultation scheduled for all THP patients. During these scheduled visits, they will be received in the gait analysis laboratory for a gait assessment (V1). Patients will be seen again at 6 months post-operatively for a second gait assessment (V2).
OTHERPatients with primary coxarthrosis (any stage) and operated with RTH (Hip resurfacing).
Patients scheduled for RTH (Hip Resurfacing) will be seen at the consultation the day before surgery, in the same hospital as the RTH, or at an existing dedicated consultation scheduled for all RTH patients. During these scheduled visits, they will be received in the gait analysis laboratory for a gait assessment (V1). Patients will be seen again at 6 months post-operatively for a second gait assessment (V2).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Amplitude degree of lower limbs articulations | 6 months |
| Dynamics of limbs joint torques during walking initiation measured in Nm/kg | 6 months |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Step width during gait initiation | 6 months | — |
| Duration of first step during gait initiation | 6 months | — |
| Duration of anticipatory postural adjustment phase during gait initiation | 6 months | — |
| Duration of execution phase during gait initiation | 6 months | — |
| Measurement of the trajectory during gait initiation | 6 months | — |
| Measurement of the amplitude of retreat of the center of pressure during gait initiation | 6 months | — |
| Severity of coxarthrosis according to the Tönnis classification | 6 Months | The severity of coxarthrosis is assessed on radiographs according to the Tönnis classification: Grade Radiographic features 0 - No signs of osteoarthritis 1. \- Slight narrowing of joint space * Slight lipping at joint margin * Slight sclerosis of the femoral head or acetabulum 2. \- Small cysts in the femoral head or acetabulum * Increasing narrowing of joint space * Moderate loss of sphericity of the femoral head 3. \- Large cysts * Severe narrowing or obliteration of joint space * Severe deformity of the femoral head * Avascular necrosis |
| Measurement of the speed during gait initiation | 6 months | — |
| PMA (Postel Merle d'Aubigné) score | 6 months | Score on 3 items (pain, mobility and walking) rated on 18 points (18 = excellent results, 0 = worst result) |
| Devane score | 6 months | Activity score with 5 possibilities (1 = sedentary work and 5 = power work, competitive sport) |
| UCLA (University of California Los Angeles) score | 6 months | Activity score comprising 10 possibilities and assessing the intensity of physical activity (1= inactive or dependent patient, 10 = regular practice of high-impact sports) |
| Vellas unipodal weight-bearing test | 6 months | This test consists in asking the patient to balance for as long as possible. A time of more than 30 seconds indicated a very low risk of falls. A time of less than 5 seconds indicates a very high risk of falls. |
| Pelvic incidence | 6 months | Pelvic incidence is a constant morphologic parameter that describes the pelvic size based on the angular relation between femoral heads and sacral plate for any given person |
| Sacral slope angle | 6 months | Spatial orientation of the pelvis in the sagittal plane is assessed by the sacral slope |
| Pelvic tilt angle | 6 months | Pelvic tilt is a position-dependent parameter defined as the angle created by a line running from the sacral endplate midpoint to the center of the bifemoral heads and the vertical axis. |
| HHS (Harris Hip Score) | 6 months | The functional score consists of 10 items out of 100 points (best score = 100 points) assessing function, pain and mobility |
| Step length during gait initiation | 6 months | — |
