Filter by:This study is in response to the Food and Drug Administration (FDA) call to all manufacturers with 510(k) clearance for metal-on-metal (MoM) total hip arthroplasty (THA) devices to conduct postmarket surveillance studies. MicroPort has various acetabular shells, acetabular liners, fixation screws, femoral heads, femoral stems, modular necks, and proximal bodies currently cleared for MoM indications. Together these components comprise the Wright Medical Technology (WMT) MoM THA System. The primary objective of the study is to determine the incidence of adverse local tissue reactions (ALTR) in each THA implanted with the WMT MoM THA System overall and to create cross-sectional epochs of ≤ 8 years and > 8 years, since implantation.
This is a single center, prospective, randomized controlled study. The primary objective of this study is to measure migration over two years with RSA. Patients will be randomized in two arms, receiving a Taperloc Complete Reduced Distal or a Taperloc Complete Microplasty hip stem.
This is a prospective, non-randomized, consecutive series, multicentre, observational study to evaluate the clinical outcome of ceramic-on- ceramic hip resurfacing arthroplasty using the ceramic, non-porous, non-cemented H1 Hip Resurfacing Arthroplasty. It includes a safety study followed by an efficacy study. Patients will be followed up for 10-years postoperatively. The primary aim is to confirm the safety of the H1 hip resurfacing prosthesis by demonstrating non-inferiority of the H1 device in terms of survivorship. The secondary is to evaluate superiority of the ceramic-on-ceramic H1 hip resurfacing prosthesis compared to Metal-on-Metal (MoM) hip resurfacing in terms of absence of metal ion release.The primary end point is revision for any reason.
Success of the hip arthroplasty depends on the measures that optimize perioperative conditions.It is planned to evaluate semi-closed loop system in the hip arthroplasty surgery.
Subjects submitted to unilateral THA will be randomized into two rehabilitation groups. One group will receive a booklet with guidelines for postoperative care, while the other group will participate in face-to-face sessions with exercises with emphasis on muscle strengthening.
Dry needling is a new treatment technique, addressed to mechanical pain of the neuromusculoskeletal system. Recent investigations has developed new hypothesis about the etiology of the osteoarthritis and could be in relation to musculoskeletal disorders, but there is no published studies evaluating the results of this technique in hip osteoarthritis patients. The objective of this trial is to evaluate if dry needling is more effective in symptoms, function, range of motion, strength, muscular length, pain threshold and compared to sham dry needling and control. For this purpose the investigators conduct a randomized controlled trial double-blind (patient and examiner). The investigators included patients diagnosed of hip osteoarthritis Grade I-III by Scale of Kellgren and Lawrence. Patients included are randomized into 3 groups one receive Dry needling, other sham dry needling and the other is a control. Groups receive 3 treatment sessions. The variables are measured at the beginning and end of treatment. And also some variables are measured before and after each session. Patients who participated in sham dry needling or control group, when the intervention finish the investigators will be given the opportunity to receive the actual technique.
Prolonged wound drainage after total hip or knee arthroplasty is a very undesirable complication, both from medical as patients view. Wound drainage prolongs hospital admission and is associated with an increased risk of infection (1) post-operative wound drainage of more than 48 hours is associated with an increased infection risk of 42 percent a day in hip arthroplasty and 27 percent a day in knee arthroplasty. (2) Patient organizations report that wound drainage is considered as one of the most undesirable complications. In our hospital, patients undergoing hip or knee arthroplasty are treated according to a "fast track" protocol, in most cases resulting in a hospital admission of only two days. This increases the chance that patient's release from hospital will be delayed due to wound drainage. The fact that our department recently started to perform hip and knee arthroplasty in a daycare setting increases this chance substantially. In hemiarthroplasty of the knee, tissue adhesive was used in addition to conventional wound closure techniques with monocryl sutures. Resorbable monocryl sutures were used so that the usual visit to our outpatient department to remove the sutures was no longer necessary. However, we experienced an increase in wound drainage and complications using only monocryl. The addition of a tissue adhesive decreased the post-operative wound complication drastically. This in mind, we started to use tissue adhesive in regular hip and knee arthroplasty as well. With tissue adhesive in addition to conventional staples, we noticed good results. These results however, were subjective and not officially recorded. In a previous study, good results are reported in decreasing wound drainage with the use of a tissue adhesive in addition to staples. Clinical relevance was not reported and the study design lacked a cost-effectiveness analysis (3) The increase in cost for the use of the tissue adhesive involved was noted by our board of directors. Because lack of a clear medical of financial benefit, we were asked to minimize the use of tissue adhesive, resulting in usage of tissue adhesive solely in a day care setting, which comprises only 5 to 10 percent of our treated population. Previous study reported a decrease in post-operative wound drainage when tissue adhesive was used in addition to staples in knee arthroplasty. However, no financial benefit is known, therefore this treatment has not been accepted into daily practice. In our department, prolonged hospital admission due to wound drainage is not found to be uncommon. Our hypothesis is that the addition of tissue adhesive in wound closure after hip and knee arthroplasty will significantly decrease post-operative wound drainage, leading to a reduced number of admission days. In addition, we expect less patients to return to our outpatient clinic for non-regular visits due to wound complications. Expensive bandages are used in our standard treatment protocol. Less wound drainage would mean less bandages. All these things combined will lead to a reduction in overall health care costs
The care for patients receiving total hip and knee arthroplasty at the University of Arkansas for Medical Sciences has followed a structured care pathway since July 2015. This system of perioperative care has focused on preoperative assessment of medical co-morbidities and risks to postoperative functional recovery, anesthetic care focused on postoperative nausea and vomiting prevention and optimizing immediate postoperative functional ability, and aggressive postoperative physical therapy. This is an observational study to look at the outcomes of this program at University of Arkansas for Medical Sciences. Areas of focus will be hospital length of stay, postoperative narcotic consumption, Visual Analog Scale scores, incidence of postoperative nausea and vomiting, and 30-day readmission rates, and health literacy rates.
The study was designed to compare the clinical outcomes of a home-based rehabilitation program using a novel digital biofeedback system against conventional home-based rehabilitation after total hip replacement This system allows the patients to perform independent rehabilitation sessions at home, under remote monitoring from the clinical team. The investigators hypothesise that the clinical outcomes of a home-based rehabilitation program will be at least similar to the outcomes of a traditional home-based rehabilitation with face-to-face sessions. This is a single-center, prospective, parallel-group pilot study with active comparator. Patients will be enrolled pre-operatively and then divided into 2 groups: experimental group and conventional rehabilitation group. Both groups will perform an 8-week rehabilitation program starting between day 7 and 10 after surgery. The experimental group will perform daily exercise sessions at home using the system, under remote monitoring from a physical therapist. The conventional rehabilitation group will perform 3 home-based rehabilitation sessions per week, each with 1h duration, given by a physical therapist. Outcomes will be measured at weeks 4 and 8 and then at 3 and 6 months. The primary outcome is the change in patient performance measured by the Timed-up-and-Go (TUG) test between in comparison with the pre-operative score. Secondary outcomes will be measured in terms of: a) Hip Osteoarthritis Outcome Score (HOOS); b) range of motion of the hip joint (lying flexion/abduction; standing flexion/adbuction/hyperextension)
Barbed suture use has been gaining increased acceptance and has been reported to offer potential advantages in wound closure of hip and knee replacement surgeries. The goal of this study is to compare joint replacement patient outcomes who receive a knotless barbed suture versus a traditional suture (randomized into two arms). The traditional suture used at our joint replacement program is defined as: interrupted sutures to close the retinaculum followed by running monocryl sutures for skin closure. Both knotless barbed suture and the traditional sutures have similar suture size. Patient outcomes examined will be patient range of motion (recorded daily) and complications with wound healing (evaluated periodically in-person at post-operative visits). Secondary outcomes examined will include wound drainage on dressings by surface area and weight, as well as the wound cosmesis and perceived presence of subcutaneous surgical knots.
