Filter by:This study aims to evaluate the return to activity in younger patients under 50 years old after undergoing either total hip replacement (THR) or hip resurfacing, as performed in everyday practice. This research will be observational, meaning patients will not be randomly assigned to different treatment groups. To objectively assess participents; return to everyday, professional, and sports activities, validated questionnaires will be sent to participents in addition to routine clinical practice. The study will be prospective and comparative based on the type of prostheses used. In order to capture the current practices of surgeons performing THR in participents under 50 years old in France, the study will be conducted at multiple centers across the country. Since hip resurfacing is performed only in certain centers, approximately half of the participating centers are experienced in this technique. Participents typically resume activity between 3 and 6 months after THR. One year of post-operative follow-up allows for an accurate assessment of participents; recovery, unaffected by the surgery. Participents ; physical activity levels will be evaluated using the UCLA Activity Scale developed by surgeons to assess the activity levels of patients undergoing hip and arthroplasty.
Pain after total hip replacement (THR) surgery is severe. The target population is elderly and comorbid. Level III analgesics are responsible for significant side effects in this population. Locoregional analgesia, by reducing the consumption of painkillers, is an effective way of reducing morphine or morphine agonist consumption in this surgery. Furthermore, these techniques fit in perfectly with the objectives of accelerated rehabilitation after surgery. Surgical infiltration is a frequently used and effective analgesic technique. PENG block is a new locoregional anesthesia technique which initial results show promising analgesic efficacy and the absence of loss of strength through motor block. In February 2022, we carried out a survey of national anesthetic practices in posterior hip arthroplasty, with the help of the SFAR (Société Française d'Anesthésie-Réanimation). It shows that, despite the lack of plentiful literature on the subject, the PENG block is currently the most frequently performed pre-operative block in hip arthroplasty (PENG block in 39.5% of cases, femoral block in 13% of cases). The survey also shows that in 41.5% of cases, no block is performed, and only intraoperative surgical infiltration is carried out. PENG block and surgical infiltration are therefore the two analgesic techniques most frequently used in France today. It is for these reasons that we feel it is essential to carry out a study comparing these two techniques.
The goal of this observational study is to evaluate the diagnostic performance of the T2 mapping technique of the following 4 MRI scans in detecting hip chondro-labral lesions in comparison with intraoperative arthroscopic findings: 1) basal 3T MRI with T2 mapping technique, 2) 3T MRI with T2 mapping technique and limb traction; 3) 3T arthro-MRI with T2 mapping technique; 4) 3T arthro-MRI with T2 mapping technique and limb traction.
The purpose of the study is
In this study, we aim to develop a statistical shape model and use it to reconstruct the shape of acetabula with severe defects (Paprosky 3a-3b). This will allow us to visualise and assess the morphology of the missing bone. In future studies we will use the obtained results to improve the design of acetabular implants for revision surgery.
Rehabilitation after primary knee or hip arthroplasty may include performing exercises with a physiotherapist. For patients who can work well with a computer, tablet or smartphone, it is now possible to use a mobile application (e.g. moveUp) to carry out a large part of the exercises more independently. This is done with online guidance by a physiotherapist via a mobile application that is CE marked in Europe. This study will investigate whether the effect of the mobile application on knee or hip rehabilitation and quality of life is equal to that of standard care (i.e. without the use of a mobile application).
Rationale of the study is to evaluate through a prospective randomized controlled study if a modified direct superior posterolateral approach (sperimental approach) to the hip articulation which entirely spares i.e. avoids the sacrifice of the fascia lata might elicit a better outcome in terms of gait, balance, strengths recovery, clinical performance, patient reported outcome measurement (Short Form-12(SF-12); Hip disability and Osteoarthritis Outcome Score (HOOS)) and overall recovery time in patients undergoing TotalHipArthroplasty with the aid of dedicated, modified instrumentation in order to properly access this modified route. The investigators expect an improvement on selected gait analysis parameters in sperimental approach in order of 2% of range of motion (ROM) recorded 1 month after surgery. Based on this assumption sample size calculation will be conducted.
The objective of this randomized control trial is to investigate effects and cost effectiveness of interprofessional preoperative assessment among older knee or hip arthroplasty patients. The main hypothesis is that preoperative assessment and optimization have a positive impact on the patents' quality of life and expenditure of social and health care services.
Periprosthetic bone-loss after total hip arthroplasty (THA), detected as an early migration of the prosthesis, may predict later loosening. The investigators hypothesized that by reducing bone resorption after THA with bisphosphonates, it might be possible to achieve better early fixation of the implant. Nineteen patients suffering arthrosis were recruited to a prospective, double-blinded, randomized, placebo-controlled clinical pilot trial. Patients were operated with an uncemented Bimetric stem with tantalum markers, the acetabular cup and liner were chosen by the surgeon. The femoral proximal intramedullary canal was rinsed with 1mM (millimole) clodronate, that was done by adding the clodronate to the 1000 ml 0.9% NaCl (sodium chloride) in nine patients and rinsing solution was the pure 0.9% NaCl for 10 patients. These rinsing packages were labeled only with the code from the pharmacy of the hospital. These patients were followed for two years using radiostereometric analysis (RSA), dual energy x-ray absorptiometry (DXA) and the Harris hip score (HHS). The purpose of the investigator's study was to examine whether the local intraoperative administration of clodronate could reduce periprosthetic bone loss and further stem migration after primary THA.
The study was designed to compare the clinical outcomes of a home-based rehabilitation program using a novel digital biofeedback system against conventional home-based rehabilitation after total hip replacement This system allows the patients to perform independent rehabilitation sessions at home, under remote monitoring from the clinical team. The investigators hypothesise that the clinical outcomes of a home-based rehabilitation program will be at least similar to the outcomes of a traditional home-based rehabilitation with face-to-face sessions. This is a single-center, prospective, parallel-group pilot study with active comparator. Patients will be enrolled pre-operatively and then divided into 2 groups: experimental group and conventional rehabilitation group. Both groups will perform an 8-week rehabilitation program starting between day 7 and 10 after surgery. The experimental group will perform daily exercise sessions at home using the system, under remote monitoring from a physical therapist. The conventional rehabilitation group will perform 3 home-based rehabilitation sessions per week, each with 1h duration, given by a physical therapist. Outcomes will be measured at weeks 4 and 8 and then at 3 and 6 months. The primary outcome is the change in patient performance measured by the Timed-up-and-Go (TUG) test between in comparison with the pre-operative score. Secondary outcomes will be measured in terms of: a) Hip Osteoarthritis Outcome Score (HOOS); b) range of motion of the hip joint (lying flexion/abduction; standing flexion/adbuction/hyperextension)
