Primary |
Evaluate the success rate of this new ultrasound-guided ilio-psoas tendon tenotomy technique |
The success of this new ultrasound-guided ilio-psoas tendon tenotomy technique will be assessed by the disappearance of the ilio-psoas conflict after surgery. This criterion will be measured at the first control consultation |
3 weeks post-operative |
|
Secondary |
Evaluate the new ultrasound-guided ilio-psoas tendon tenotomy technique compared to standard practice on pain experienced by the patient |
The pain felt by the patient will be collected using a numerical scale from 0 to 10 before surgery, 3 hours after surgery, the day after surgery, then 3 weeks, 6 weeks, 3 months and 6 months after surgery. Zero '0', means that the patient has no pain ; '10', means that the patient has extreme pain. The non-inferiority limit is set at 1.5 on the pain EVA scale |
Pre-operative, 3 hours, 1 day, 3 weeks, 6 weeks, 3 and 6 months post-operative |
|
Secondary |
Evaluate the Oxford Hip Score |
The Oxford Hip Score is a questionnaire that assesses pain and hip function of patients who have undergone total hip replacement surgery. Patient should reflect on their pain and functional abilities on the previous 4 weeks. The questionnaire is divided into 2 domains (pain and function), each domain being composed of 6 questions. For each question, 5 answers are possible, each with a score of 0 to 4 (None = 4, Minimal = 3, Slight = 2, Moderate = 1, Severe = 0). The total score ranges from 0 (most severe symptoms) to 48 (no symptoms). |
At baseline, 3 weeks, 6 weeks, 3 and 6 months post-operative |
|
Secondary |
Evaluate the Harris Hip Score |
The Harris Hip Score assess the results of hip surgery. It is composed of 10 questions divided into 4 domains (pain, function without deformation and amplitude of movements). A score is assigned to each response. The total score varies from 0 to 100. The higher the score, the better the results and the less dysfunctional the patient |
At baseline, 3 weeks, 6 weeks, 3 and 6 months post-operative |
|
Secondary |
Evaluation the Postel and Merle Aubigne score |
the Postel and Merle Aubigne score measures pain, joint mobility and walking. For each question, 6 answers are possible, each one having a score of 0 to 6. The total score varies from 0 to 18, 18 indicating a perfect hip |
At baseline, 3 weeks, 6 weeks, 3 and 6 months post-operative |
|
Secondary |
Evaluate the technical difficulty of surgical procedure |
The technical difficulty of surgical procedure will be assessed using a 4-point Likert scale: on the day of the operation, the surgeon will have to answer the question "What was the difficulty experienced by you in the operation?". He may answer by: Very difficult, difficult, moderately difficult or easy. |
the day after surgery |
|
Secondary |
Evaluate the operative time |
The operative time will be expressed in minutes between skin incision and skin closure |
the day of surgery |
|
Secondary |
Evaluate the installation time |
The installation time will be expressed in minutes between the end of intubation and the beginning of the brush |
the day of surgery |
|
Secondary |
Evaluate the total blood loss |
Total blood loss will be calculated according to the ostheo formula, including pre-operative (in the month preceding the surgery) and post-operative (the day after surgery) hematocrit values. This measure makes it possible to accurately assess the hidden blood losses related to the hematic extravasation |
in the month before surgery and the day after surgery |
|
Secondary |
Evaluate the length of hospital stay |
The length of hospital stay will be expressed in hours, between the entry and the discharge of the patient |
the day after surgery |
|
Secondary |
Evaluate the scarring after surgery |
The scarring after surgery will be evaluated at 6 weeks after surgery using a subjective scar satisfaction score (4-point Likert scale), transmitted by the patient himself. The patient will have to answer the question "Are you satisfied with your scar?". He can answer: Very satisfied, satisfied, dissatisfied or very dissatisfied. |
6 weeks post-operative |
|
Secondary |
Evaluate the impact of the patient's quality of life |
Quality of life will be evaluated using the EuroQol five-dimension questionnaire (EQ-5D-5L), at inclusion, 6 weeks, 3 and 6 months after surgery.The EQ-5D-5L comprises a descriptive system and a visual analogue scale (VAS). The descriptive system is composed of five health dimensions (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) with 5 levels of health (no problems, slight problems, moderate problems, severe problems and extreme problems). For each of the 5 dimensions, the participant's answer is converted to a number between 1 and 5, expressing the health state reported. The responses are combined to produce a five-digit number describing the participant's health status which is converted to a utility value from the country specific value set. The French EQ-5D-5L value set has utility between -0.530 (health condition worse than death) and 1 (best possible health). The VAS records the self-rated health status on a graduated scale from 0 to 100. |
At baseline, 6 weeks, 3 and 6 months post-operative |
|
Secondary |
Evaluate the patient satisfaction with the results of the operation |
Patient satisfaction will be assessed at 3 weeks, 6 weeks, 3 months and 6 months post-surgery using a 4-point Likert scale. To do this, the patient will have to answer the question: "Are you satisfied with the results of your surgery?". They can answer with: very satisfied, satisfied, dissatisfied, or very dissatisfied. |
3 weeks, 6 weeks, 3 and 6 months post-operative |
|
Secondary |
Evaluate the subjective value of the hip |
The subjective value of the hip will be assessed at inclusion, 3 weeks, 6 weeks, 3 months and 6 months after surgery by the patient himself. By answering the question "What then is the overall percentage value of your hip if a completely normal hip equals 100%?" , the patient should assess his hip on a scale of 0 to 100, 100 corresponding to a perfect hip. |
at baseline, 3 weeks, 6 weeks, 3 and 6 months post-operative |
|
Secondary |
Evaluate the forgotten hip sensation |
The forgotten hip sensation will be assessed by the patient himself at 3 weeks, 6 weeks, 3 months and 6 months after surgery by answering the question "Have you forgotten your hip?". The patient can answer yes or no. |
3 weeks, 6 weeks, 3 and 6 months post-operative |
|
Secondary |
Evaluate the Forgotten Hip score. |
The forgotten hip score will be assessed at inclusion, 6 weeks, 3 and 6 months after surgery. The score is composed of 12 questions assessing the degree of forgetfulness. For each question, the patient may respond with never, almost never, rarely, sometimes, often. |
at baseline, 6 weeks, 3 and 6 months post-operative |
|
Secondary |
Evaluate the early (< 90 days) and late (> 90 days) surgical complications related to surgery |
Early complications (< 90 days after surgery) and late complications (> 90 days after surgery) will be sought the day after surgery and throughout the follow-up period. They will be classified as major (infections at the surgical site or medical complications increasing the length of hospitalization) or minor according to the series of the literature |
During 6 months after surgery |
|
Secondary |
