Active clinical trials for "Osteoarthritis, Hip"

Introduction: Femoral and acetabular replacement is characterized as total hip arthroplasty (THA). It has been used as treatment of various pathologies of this joint. In the postoperative period, some studies have shown that strength, function, range of motion and lower limb mechanics remains altered for more than One year after THA in relation to the non-operated side. However, studies that have correlated kinematics and hip muscle strength in individuals who underwent THA for long time, do not exist in literature. Objective: to evaluate lower limb muscle strength and 2D kinematics during stair ascending and descending in patients undergoing total hip arthroplasty. Methods: Third individuals who underwent total hip arthroplasty (THA) will be recruited at two, five and 10 year postoperative periods. They were allocated in three groups: Group 1 (10n), subjects submitted to THA for two years, Group 2 (10n) subjects submitted to THA for five years, Group 3 (10n) subjects submitted to THA for 10 years and Group 4 (10n) subjects without orthopaedic afections, all will be evaluated for dynamometric isometric muscle strength and kinematic analysis of stair ascending and descending by a "blinded" physical Therapist.

A retrospective consecutive population of patients treated with cementless total hip arthroplasty with ceramic-on-ceramic bearing surfaces due to post-traumatic osteoarthritis due to acetabular fractures will be selected. The aim of this retrospective study is to evaluate the long-term clinical and radiographic results of this implant in such a specific cohort. The secondary aim of the sudy is to provide the complication rate and the failure rate of the cohort. A descriptive analysis of the failures will be provided as well.

The purpose of this study is to obtain long-term (10+ yrs) clinical and patient outcomes data on patients who received the Revelation Hip Stem prior to 2002.

The purpose of this prospective clinical data-collection is to document the performance and clinical outcomes of the Balance® Microplasty™ Hip System.

The goals of this study are to identify predictors of improvement in quality of life and satisfaction with total hip arthroplasty three to five years after surgery.

A Quality Study in the use of Post-Anaesthesia Care Unit(PACU) in Hip and Knee Arthroplasty, and the ability to bypass this unit. The investigators wish to investigate the amount of patients who is required to be secondary admitted to the PACU, after primary discharge from the operating room to the surgical ward, thereby bypassing the PACU.

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.

This study compares the change (loss) of bone mineral density (BMD) that occurs in the proximal femur after hip resurfacing and total hip replacement.

Research with DXA has shown the pattern of bone remodelling around an implant. The baseline and reference value for such calculations is the first measurement after the operation. The baseline measurement is performed at different time from study to study. If there is a rapid bone loss the first weeks after an operation, this will influence the reference value and then the results. To evaluate DXA as a method we decided to set up a study with 3 DXA measurements within the first 2 weeks. Our hypothesis is that there is a rapid bone loss the first 2 weeks after operation and that timing of the first post operative measurement will influence the later results.

The purpose of this study is to investigate the utility of fentanyl matrix for the treatment of pain due to osteoarthritis (OA) of knee or hip, which was not adequately controlled by non-opioid analgesic (e.g. NSAIDs or COX-II inhibitors) or weak opioids [tramadol HClacetaminophen, tramadol or codeine (or combinations with acetaminophen/ibuprofen)].
