An interventional study of Patients with primary coxarthrosis (any stage). and Patients with primary coxarthrosis (any stage) and operated with Total Hip Prosthesis (THP). in Primary; Coxarthrosis, sponsored by Lille Catholic University. Recruiting at 2 sites in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2024-09-19.
Sponsored by Lille Catholic University · Not applicable, Interventional, and Other
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).
641 studies on the registry are indexed under Osteoarthritis, Hip; 120 are open to participants now.

Exclusion Criteria:
Symptomatic contralateral hip/knee disease Symptomatic gonarthrosis or homolateral total knee prosthesis History of surgery on the affected hip History of fracture of the lower limb in the past year History of lower limb sprain in the last 3 months Neurological or degenerative disease
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).
Patients who do not undergo surgery will be called specifically for the study to attend a consultation dedicated to gait assessment.
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).
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).

Severity of coxarthrosis according to the Tönnis classification
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
Time frame: 6 Months
HHS (Harris Hip Score)
The functional score consists of 10 items out of 100 points (best score = 100 points) assessing function, pain and mobility
Time frame: 6 months
PMA (Postel Merle d'Aubigné) score
Score on 3 items (pain, mobility and walking) rated on 18 points (18 = excellent results, 0 = worst result)
Time frame: 6 months
Devane score
Activity score with 5 possibilities (1 = sedentary work and 5 = power work, competitive sport)
Time frame: 6 months
UCLA (University of California Los Angeles) score
Activity score comprising 10 possibilities and assessing the intensity of physical activity (1= inactive or dependent patient, 10 = regular practice of high-impact sports)
Time frame: 6 months
Vellas unipodal weight-bearing test
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.
Time frame: 6 months
Pelvic incidence
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
Time frame: 6 months
Sacral slope angle
Spatial orientation of the pelvis in the sagittal plane is assessed by the sacral slope
Time frame: 6 months
Pelvic tilt angle
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.
Time frame: 6 months
