Filter by:Study purpose is to evaluate perioperative usefulness of Platelet-rich Plasma (PRP) in total hip arthroplasty (THA) surgery. The study is designed as a randomized double blinded study using saline as placebo. The measurement outcomes includes objective variables (MRI, dynamometer) as well as subjective measurements (Oxford Hip Score, Harris Hip Score). Patients are assigned to two different groups, according to a randomization list. PRP (approximately 9ml from which 1ml is delivered to in-house laboratory for the measurement of platelet count) is obtained from venous blood and applied to m. gluteus medius during the closure of modified lateral approach (Hardinge). Study participants are evaluated preoperatively by trained physiotherapist. After surgery, participants undergo clinical evaluation and imaged (MRI) at 3 and 12 months post-operative. In the same time points, strength, Harris Hip Score and Oxford Hip Score. At the end of the study, the nature of the injected substance is revealed to the patients.
In total hip arthroplasty, cup anteversion is an important factor in stability. Lewinnek's safe zone and functional anteversion are often used to assess appropriate orientation. However, these approaches do not consider the effect of the spinopelvic chain and lumbar mobility when in the seated position. This study will measure functional anteversion when standing and sitting with patient-specific computer models and define a quantitative relationship between the change in functional anteversion and spinopelvic parameters. This will challenge the historical paradigm of the safe zone and provide a tool to define anteversion based on a patient's mechanics and reduce risk of dislocation.
Hip osteoarthritis (HOA) is a common cause of pain and disability in aging population. Conservative treatment is based on lifestyle modifications, physical therapy, analgesic and anti-inflammatory medications and intra articular injections. This Prospective Pilot Study aims at investigating the efficacy of Ultrasound-Guided Cooled Radiofrequency Hip Denervation as a treatment offered to patients with HOA.
In orthopaedic manual therapy translatoric grades of movement are used to determine the intensity of force applied during the mobilization. Different clinical effects are described for each translatoric grade of movement but there are not published studies evaluating these clinical effects. The objective of this trial is to determine if force magnitude during hip traction in resting position affects immediate and short-term outcomes (pain, physical function, hip muscle length and hip range of motion) in patients with hip osteoarthritis. For this purpose, investigators conduct a randomized clinical trial, double-blind (patient and physical therapist examiner). Participants entering the study were randomized into 1 of 3 treatment groups: grade I- grade IISZ mobilization, grade IITZ mobilization or grade III mobilization. Participants attend three sessions on alternate days (monday, wednesday, friday) and at the same hour. Measurements are taken prior to treatment, immediately after each session treatment. The participants are recruited from physiotherapy groups or referred by general practitioners and orthopedic surgeons. Participants were assigned to 1 of the 3 study groups through concealed allocation (sealed envelopes) and independent blocked randomization, using a random number generator. One physical therapist enroll patients in the study, while an independent research assistant performed the randomization and prepared the sealed envelopes, which are opened after baseline data collection by the physiotherapist performing the treatments. Participants are treated in a private treatment area and have no knowledge of treatments received by other participants. A second experienced orthopaedic manual therapist applies the standardized hip traction mobilization in resting position at either level of force, during 10 minutes. This amount of mobilization is consistent with clinical practice and previous studies in osteoarthritis patients. Two physiotherapists (third and fourth) with 5 years of experience, who were blinded to participant group, performed all measurements.The outcome measures are pain, physical function, hip muscle length and hip passive range of motion. Pain is registered with visual analogic scale (VAS), Pressure Pain Threshold ( PPT) and WOMAC pain subscale. Physical function is registered using Timed Up & Go test (TUG), the 20-Meter Walking Test (20MWT) and the physical function subscale of WOMAC index. The hip muscle length is measured using Ely´s test, Active Knee Extension test and modified Ober´s test. The passive hip range of motion is measured using inclinometer or goniometer.
To date, detailed analysis of movement patterns in orthopaedic conditions are mainly performed in research projects. Because these tests are time consuming, they are not feasible in clinical routine or in standard examinations. Novel technologies allow capturing detailed movement patters within a few minutes. The aim of this regional study is to compare aspects of movement tasks measured using a mobile gait analysis system to those measured using laboratory based systems and to determine aspects of gait patterns relevant for different orthopaedic conditions. Moreover, the researchers will investigate if these relevant aspects can be altered using surgical treatment or manual therapy.
Previous research has shown that the osteoarthritis care for persons with hip or knee osteoarthritis in Norway has a potential for improvement as the provided care may not necessarily reflect evidence-based guideline recommendations. This study will determine if a new model for integrated osteoarthritis (OA) care in primary health care will result in improved quality of osteoarthritis care and health benefits for the patients (reduced pain and body weight, increased function and activity level) among patients with hip and/or knee osteoarthritis. Further, this study will examine if the new model reduce the number of unnecessary referrals to Magnetic Resonance Imaging (MRI) and to orthopaedic surgeons in secondary care, and if it increases the number of referrals to physiotherapy treatment and the number of discharge reports from the physiotherapists to the referring general practitioner.
The purpose of this trial is to evaluate a new method of applying hydroxyapatite coatings on cement-less femoral stems.
The investigators goal is to provide a mechanism that allows for a better understanding of patient outcomes following rehabilitation. This includes functional outcomes measured by standardized and validated tools from the published literature. It incorporates comorbidities and patient demographic characteristics. It includes measures of general health as well along with activities of daily living and behavioral health aspects. Measures of quality and satisfaction and use of Net Promoter Scores also are included. All of these components come together to form a remarkably comprehensive picture of patients and their associated outcomes. This is a unique milestone in rehabilitative care and will act to inform and direct evidence-based approaches and treatment guidelines. Data are collected via the investigators proprietary electronic medical record system and are synthetic to the clinical process—that is, the data are collected in real-time with patients and the scores are immediately provided to the treating therapist as well as archived for later Registry and scientific use. Subsequent reporting can be risk adjusted to any variable collected which yields robust insights as to idiopathic patient conditions. However, no PHI information will be available.
The purpose of the study is to evaluate the effectiveness of an approach based on neurocognitive rehabilitation exercises in the form of sensory-motor problems, whose solution involves the use of higher cognitive functions (attention, memory, language), not required in a traditional approach proprioceptive, in order to obtain a more complete and long-lasting recovery.
The primary objective of this study is to determine whether the Mini Hip (Corin, U.K.) femoral component has a predictable and stable migration pattern (mean migration of the femoral component in three-dimensions,in mm) over a three year period, compared to a conventional cementless stem (Metafix, Corin, U.K.). The secondary objectives of this study are to determine whether the Trinity (Corin, U.K.) acetabular component has a predictable and stable migration pattern over a three year period and to measure the linear wear of femoral head into the ECIMA Highly Cross-linked polyethylene.
