Active clinical trials for "Osteoarthritis, Hip"

The aim of this project is to investigate prosthesis fixation in the bone, respectively cemented and uncemented operation method of Avantage® dual-mobility acetabular cup in elderly patients, wear of the plastic in dual-mobility hip prosthesis and evaluate the clinical function, patient satisfaction and possible complications. Patients included in this study suffer from osteoarthritis of the hip.

The Zimmer Hip Resurfacing System Post-Market Clinical Follow-up study will examine the safety and efficacy of this device in the young and/or active patient with advanced hip disease.

This is a randomized control trial that will investigate whether a collared hip replacement implant provides greater stability compared to a collarless option. Stability will be measured by implant migration with radiostereometric analysis (RSA) imaging. Secondary objectives will be to compare function, quality of life and cost between the two implant types. We will also compare between two different surgical approaches, the direct anterior and direct lateral.

The objectives of treatment in hip osteoarthritis are pain relief, improve joint range of motion and muscle force, gait rehabilitation, patient education and socio-professional reintegration.The non-pharmacological and non-surgical methods include certain types of physical therapy: massage, heat, ultrasound, laser, shockwave therapy. Few studies have been conducted so far for outcome measurement in symptomatic hip osteoarthritis.

The aim of this study was to assess the effects of dry needling technique on muscle strength and muscle length in patients with hip osteoarthritis at short term.

Osteoarthritis (OA) is a common disease that occurs more commonly amongst the elderly and is caused by the destruction of the joint cartilage. It is considered to be one of the most common joint disorders worldwide and a main cause of disability amongst older adults. After the knee, the hip is considered to be the second most commonly affected joint by OA. One of the functional capacities affected by OA is muscle strength with studies looking into knee OA documenting a decrement of this measure. It is reported that the muscle strength of the quadriceps, hamstrings and other musculature around the hip is significantly impaired in patients with knee OA compared to age-matched controls. Evidence for quadriceps muscle weakness in knee OA is consistent and programs based on quadriceps strengthening exercises as a core component in the management of knee OA are now evidence-based. Lower extremity muscle weakness is also apparent in hip OA. However, compared to the knee, there is less literature on muscle strength in hip OA with guidelines for therapeutic exercise prescription being more expert rather than evidence-based. Therefore, one of the major questions that arises here is whether muscle weakness as observed in knee OA is evident in hip OA, and if so, which muscles are most affected. A concept which has been found to help diminish the effect of decreased muscle strength in the above mentioned muscle groups is optimal core stability. Core stability contributes to strength, endurance, flexibility and motor control all of which optimise the stability of the spine during both dynamic and static tasks in daily normal biomechanical function in patients with a diagnosis of OA knees. Despite such evidence, no studies to the knowledge of the researcher have looked into the effects of core stability on pain and functional levels in patients with a diagnosis of OA hip. A lack of literature in relation to this aspect is due to the unavailability of a gold standard for measuring core stability. Therefore, the objective of this study will be multifold with an investigation into which muscles in the lower limb are predominantly weaker, whether there is core muscle weakness in patients with hip OA, looking for any correlation between both these factors and whether an exercise programme leads to changes on functional activity and pain levels.

This is a single-site, two-arm, parallel-group randomized clinical trial (RCT). The feasibility, acceptability, and clinical effects of the nurse-led, very brief, preoperative mindfulness based intervention for hip and knee replacement patients will be investigated relative to nurse-led preoperative pain psychoeducation. A secondary sub-analysis will compare two different styles of mindfulness practice (mindfulness of breath vs. mindfulness of pain) relative to preoperative pain psychoeducation.

Action Observation Therapy (AOT) and Motor Imagery (MI) are two rehabilitation approaches based on Mirror Neuron System (MNS). The MNS refers to a series of neurons able to activate both when one observes an action being performed or when one physically performs the action themselves. Previous studies reported that functional recovery is facilitated by asking patient observing videos with motor content (AOT) and after imagining (MI) the gestures observed. These rehabilitative apporach have been used in particular to promote functional recovery in patients with neuromotor problems, in particular in patients with stroke. To date, few studies have investigated the effectiveness of this therapeutic approach in functional recovery after orthopedic surgery and none of these applied AOT and MI in a single pre-operative session. The objective of the study is to verify whether a single administration consisting of two pre-operative sessions of AOT associated with MI can lead to an improvement of functional recovery in hip arthroplasty patients.

The main objective of the study is to compare the use of single-use ancillary reaming material during total hip replacement and conventional reusable ancillary reaming material. The assessment will focus on the medico-economic differences found in this prospective randomized study

The study is designed to investigate the effect of physical surroundings on the effect of exercise therapy for knee and hip pain.
