Gait Initiation and Transition From Double to Single Support in Patients With Unilateral Primary Coxarthrosis
- Conditions
- Primary; Coxarthrosis
- Interventions
- Other: Patients with primary coxarthrosis (any stage).Other: Patients with primary coxarthrosis (any stage) and operated with Total Hip Prosthesis (THP).Other: Patients with primary coxarthrosis (any stage) and operated with RTH (Hip resurfacing).
- Registration Number
- NCT06258369
- Lead Sponsor
- Lille Catholic University
- 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).

- Primary Outcome Measures
Name Time Method Amplitude degree of lower limbs articulations 6 months Dynamics of limbs joint torques during walking initiation measured in Nm/kg 6 months
- Secondary Outcome Measures
Name Time Method Duration of anticipatory postural adjustment phase during gait initiation 6 months Duration of execution phase during gait initiation 6 months Measurement of the amplitude of retreat of the center of pressure 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)
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
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.
Step width during gait initiation 6 months Step length during gait initiation 6 months Measurement of the trajectory during gait initiation 6 months Measurement of the speed 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 necrosisHHS (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
Duration of first step during gait initiation 6 months 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.
Sacral slope angle 6 months Spatial orientation of the pelvis in the sagittal plane is assessed by the sacral slope
