Gait Initiation and Transition From Double to Single Support in Patients With Unilateral Primary Coxarthrosis (COXAM)

Lille Catholic University

Status: Enrolling

Conditions: Primary; Coxarthrosis

Treatments: Other: Patients with primary coxarthrosis (any stage).; Other: Patients with primary coxarthrosis (any stage) and operated with RTH (Hip resurfacing).; Other: Patients with primary coxarthrosis (any stage) and operated with Total Hip Prosthesis (THP).

Study type: Interventional

Details and patient eligibility

About

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).

Enrollment: 100 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Men or women aged 18 and over
• With primary coxarthrosis (any stage)
• Consulting in the orthopedic departments of participating centers in anticipation of hip surgery (PTH/RTH), or for advice only.
• Written consent signed by the patient
• Affiliation with a social security scheme

Exclusion criteria

• Disabling orthopaedic conditions:

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
