The study will analyze hip biomechanical parameters using EOS radiographic measurements pre- and post-operatively (3 months) and post-operatively (3 months) CT scans after total hip replacement (THR), neck-preserving THR of the Minihip type or hip resurfacing (HR). Clinical results will be assessed at 3 months and 1 year after surgery. To this end, two types of examination are carried out, both of which are used in current practice: * Pre-operatively: EOS radiography * Post-operatively: EOS radiograph and CT scan Inclusion (m-3; m-1) : * Patient information at pre-operative visit * Non-opposition of patient, family member or legal guardian, if applicable * Questionnaires and clinical examination (standard management) * EOS during anesthetic consultation Follow-up visit (m+3): \- Post-operative follow-up consultation EOS and CT scan (1 week prior to visit) + questionnaire and clinical examination Follow-up visit (m+12): \- Post-operative check-up, questionnaire and clinical examination
NCT04943328

A randomized controlled trial comparing modular dual mobility inserts with ceramic multilayer coating versus standard polyethylene inserts for primary THA in a cementless acetabular cup
NCT04317872
This randomized, single surgeon, placebo controlled, double blind study will be conducted in order to investigate whether or not peri-operative high doses of intravenous glucocorticoids improve short-term functional outcome after direct anterior total hip arthroplasty. So far, it has been proven that high dose glucocorticoids reduce immediate post-operative pain and nausea, but no data exists on functional outcome during the first 6 weeks. Our hypothesis is that patients in the intervention group will follow a so-called "get ahead, stay ahead" principle and that glucocorticoids can be considered an important tool (adjuvant treatment) in the enhanced recovery pathway after THA with significant socio-economic implications.

One of the goals of Total Hip Arthroplasty (THA) is to reconstruct leg length as adequately as possible. In order to achieve this one needs landmarks that are visible both on the templating X ray as well as during surgery. The classical posterior and lateral approaches often rely on the distance from the greater trochanter (GT) to the shoulder of the femoral stem or the distance from the lesser trochanter (LT) to the side of the neck osteotomy. If the surgeon finds out on the digital template that the distance from the GT to the shoulder of the implant should be X mm to achieve equal leg length, than the surgeon can try to reconstruct this during surgery. During the Direct Anterior Approach (DAA) these landmarks usually are not visible or require additional dissection injuring important soft tissue structures along the way. One anatomical structure that appears to be always visible during the DAA is the External Obturator tendon (EO). It was recently confirmed that the level of insertion of the EO onto the proximal femur can also always be determined on pre-operative X rays. It therefore represents one of the few landmarks that is visible both on the templating X ray as well as during DAA THA. Indeed, many hip surgeons, including ourselves, believe that if the shoulder of the femoral stem is near the insertion of the EO leg length cannot be far off. However, there is no clinical data to support this. The investigators would therefore like to the correlate the distance observed intra-operatively to the actual established distance on the post-operative X ray.
NCT06034418
Our aim in this interventional study is to investigate the effectiveness of pulsed radiofrequency (PRF) treatment applied to the articular branches of the femoral and obturator nerves on pain, functional level, functional capacity and quality of life in patients with coxarthrosis. We will compare the effects of PRF treatment added to nerve block compared to nerve block alone.
NCT05763368
Disturbances of balance and postural stability are frequent in patients with coxarthrosis due to the damage to the mechanoreceptors, characteristic of arthritic degeneration, and muscular hypotrophy of the affected limb. The aim of the study is to evaluate with adequate instrumentation the alterations of proprioception and postural control in patients with hip osteoarthrosis and the effectiveness of joint reconstruction in improving any deficit.
NCT05343195
Task-oriented leg exercise are commonly used after joint surgeries in various hip pathologies. Based on this theory, it was hypothesized that task-oriented exercise without conventional physiotherapy can have better result in recovery of balance and leg function than with a conventional post-hip physiotherapy program after hip replacement surgery. The aim of the study was to determine the effect of task-oriented exercise on balance and leg function after total hip replacement.
NCT04500093
Total hip arthroplasty (THA) has been successful in relieving pain and restoring function in patients with advanced arthritis of the hip joint. Increased focus on earlier recovery and decreased postoperative pain has improved overall satisfaction. However, there is still a gap between the clinical scores in objective surveys and patient satisfaction. Direct anterior approach total hip arthroplasty has a low dislocation rate, abductor strength restoration, acceleration, and cosmetic advantages. In this method, capsulotomy with repair or capsulectomy is applied as the preferences of surgeons. Therefore, this can cause both a decrease in hip flexion strength and a loss in knee extension strength. Our aim in this study is to reveal how much muscle loss was caused by comparing both methods with the intact side.
NCT04424628
This is a non-inferiority study in which the investigators compare two low-dose radiotherapy schemes, which are recommended from DEGRO Clinical Practice Guidelines (3 Gy vs 6 Gy) for the treatment of osteoarthritis and other osteodegenerative disorders. A first randomization will be carried out among the patients included in the study: * Patients in arm A will be treated at 3 Gy (0.5 Gy/fraction, 3 fractions/week), and patients in arm B will be treated at 6 Gy (1 Gy/fraction, 3 fractions/week). * Patients should not know the arm to which they have been randomized. * Once the treatment is finished, patients will be assessed at 8 weeks. If pain does not improve, a re-irradiation will be performed. If the patients were treated with 3 Gy a new randomization will be performed (3 vs 6 Gy again). If the patiens were treated with 6 Gy they will be re-irradiated with 6 Gy again. The investigators will analyze the results obtained depending on the dose received and depending on the location of the treatment.

NCT01435850
Randomized controlled trial using two types of hip stems, SL PLUS MIA (control group) and SL PLUS (study group). We compare primary and secondary stability of both hip stems for radiographic outcome using EBRA (Ein-Bild-Roentgen-Analyse) after a two year follow-up period. Further, we compare all differences in clinical outcome using Harris Hip Score, Oxford hip score and radiographic findings.
NCT00722982
Hypothesis: Migration of C-Stem AMT is equal to the well documented Exeter prosthesis In Norway it is annually performed approximately 600 primary and 100 revisions THA. Osteolysis around the prosthesis is one of the major difficulties while performing revision surgery. C-stem is a triple tapered cemented prosthesis designed to increase the stress and strain of proximal femur and thereby decreasing osteolysis. We are planning til include 70 patients and randomize to C-stem AMT or Exeter prosthesis. Both prosthesis will be combined with previously non documented "Marathon" acetabular prosthesis. The result will be followed clinically and with RSA and DXA. Soft endpoint after 2 years
NCT01229774
The primary aim of this study is to test if etoricoxib decreases the perioperative blood loss compared to diclofenac. Secondary questions to be explored are: * Does etoricoxib prevent Heterotopic ossification after Total Hip Arthroplasty as well as diclofenac ? * Do diclofenac and etoricoxib both reduce pain at rest and on movements? * Does etoricoxib compared to diclofenac reduce the amount of rescue medication (Oxycodon)? * Does etoricoxib improve gastrointestinal tolerability compared to diclofenac?
NCT01578746
In total hip arthroplasty several approaches can be used. The newly introduced minimally invasive anterior approach is supposed to cause less damage to tendons and muscles. At the same time there are reports that there are more complications when this approach is used. The direct lateral approach is the most used in Norway and is well documented. There are however those who postulate that there is to high risk of damage to the gluteus medius causing Trendelenburg gait. In the investigators hospital both the anterior and direct lateral approach is used with good result. The investigators main study hypothesis is that there is no difference between the use of anterior or direct lateral approach i total hip arthroplasty in regards to postoperative function and pain, complications, radiological finds (X-ray and MRI), markers for muscle damage (i.e CK-total) or other clinical outcomes.
