NCT07337642
This is a prospective randomized control trial comparing two collared and collarless femoral implants used in primary total hip arthroplasty. The specific aims of this trial are to: SA1: Prospectively assess clinical outcomes in patients undergoing primary total hip arthroplasty with a collared versus collarless femoral stem of the same design. SA2: Evaluate serial radiographs to quantify differences in subsidence between collared and collarless implant groups. SA3: Report and compare incidence rates of intraoperative and postoperative periprosthetic fractures and aseptic loosening following primary total hip arthroplasty with use of either a collared or collarless stem. Hypothesis: The addition of a collar to the same designed triple-taper primary hip stem will lead to a reduction in subsidence and incidence of perioperative and periprosthetic femur fractures.
NCT05313321
The investigators primary objective of this study is to evaluate radiographic fit and fill of the Insignia stem and identify risk factors for aseptic failure. The investigators hypotheses being tested is: the newly designed Insignia stem demonstrates acceptable radiographic fit and fill by reviewing radiolucent lines \<2mm.
NCT04122157
Summary from initial protocol Goal: Validation of the uncoated SL-PLUS® MIA stem within an observation study Study design: prospective, single-center, observational, non-comparative study Study population: 135 consecutive cases (uncoated SL-PLUS® MIA implants) Intervention (if applicable): Implantation of a total hip endoprosthesis Main goals/endpoints: Radiological: radiolucent lines, osteolysis, hypo- and hypertrophy of the cortex, loosening of the implant or migration; clinical: Harris Hip Score, implant-related complications, revisions; patient questionnaire (WOMAC) Type and extent of the risks associated with the study participation as well as benefits for the patient: All patients will benefit from the hip prostheses without exception. There are no increased risks for the patients participating in the study compared to patients who do not participate. Normal, necessary follow-up exams will be performed over the course of 10 years. These follow-up exams will then be quantitatively evaluated within the scope of the study in accordance with a standardized protocol. Accordingly, the benefit for the patients from the participation in the study is currently not yet foreseeable.
NCT03968939
To compare non-prescription sleep aids (low-dose diphenhydramine and melatonin) to sleep hygiene education for improving postoperative sleep quality after total joint arthroplasty.
NCT03956381
The primary objective of this study is to determine the accuracy of the Optimized Positioning System (OPS™) planning and delivery tools using different types of surgical approaches.
NCT04085640
Interest of obturator nerve block for analgesia in total hip arthroplasty remains controversial. This regional anesthesia procedure could provide post-operative pain relief as obturator nerve is responsible for innervation of the internal part of the hip joint capsule. This randomized double-blind study aims to assess obturator nerve block for post-operative analgesia in total hip arthroplasty. Before the surgery, an ultrasound guided obturator nerve block will be performed with either 20cc of saline or ropivacaine 0.2% (a long-acting local anesthetics). After regional anesthesia, a general anesthesia will be performed for intraoperative period. This study aims to assess post-operative pain management during the first 24 hours. Ability to walk the day of the surgery will also be collected.
NCT04209374
This is a single-center retrospective observational cohort study of consecutively operated patients who underwent primary total hip arthroplasty with a SYMBOL CUP DM HA hemispherical dual mobility acetabular implant. The purpose of this study is to estimate the safety and efficacy of that implant at two-year follow-up.
NCT01495546
In Brazil, several hip surgeries performed, especially total knee arthroplasty, which represents 1.5 million procedures (Penedo, New, 2007). The rehabilitation of these individuals is slow with respect to the march because it requires an aid and not to use the operated leg as support for three weeks, according to conventional methods. After the third week, the support becomes part and after that period (sixth week), the support becomes total. Therefore, and in order to provide better quality of life, the goal of this work is to compare the march in 40 patients divided into two groups of 20 subjects each. In the control group, the treatment approach is the traditional, i.e., without immediate loading, while the other charge will be applied immediately in the operated limb. In order to verify the possible gain in the quality of life of these patients, the SF-36 will be applied. The march will be assessed with the Time Up and Go test and the force platform and the Harris Hip score analyze the function of the hip. Individuals will receive such care at the Institute of Orthopedics and Traumatology, Hospital das Clinicas, Faculty of Medicine, University of São Paulo (IOT - HC - USP). The results of comparisons between the two groups and the clinical findings obtained will be subjected to appropriate statistical tests, guided by the principles of evidence-based clinical practice, seeking to facilitate and improve the lives of these individuals so they can move freely.
