Filter by:The causes for total hip arthroplasty (THA) in Taiwan include ischemic necrosis of the femoral head and degenerative osteoarthritis. Contemporary, the surgical approach for total hip replacement mostly adopts the lateral approach. However, the direct anterior approach (DAA) has gained attention gradually due to its characteristics such as muscle preservation, small surgical incision length, and few surgical complications. Nevertheless, literature lacks detailed exploration or long-term follow-up on the recovery of physical functions related to fall occurrence after this type of surgery. It limits the establishment and design of suitable post-operative rehabilitation plans. Therefore, this study aims to explore and follow-up the functional recovery in patients who undergo the DAA for hip replacement using current usual care and new-designed accelerated rehabilitation program. The proposed method involves recruiting 30 patients who will undergo the DAA for total hip replacement, who will receive the current usual care plan; and another 30 patients will receive the accelerated rehabilitation program. The assessments will be conducted before the surgery and at 2, 4, 8, and 12 weeks after the operation, evaluating hip joint function, hip abduction and flexion muscle strength, balance function, and gait performance. The statistical analysis will utilize mixed-model two-factor ANOVA, comparing the preoperative and postoperative recovery of patients undergoing the DAA with different intervention programs and at different time points. The expected outcome of this study is to enhance the understanding of the functional recovery of patients undergoing the DAA for total hip replacement in terms of hip joint function, muscle strength, balance function, and gait performance after surgery. This information will help establish the targeted DAA postoperative treatment plans, which will be practically applied to patients and compared with the current usual care to assess its effectiveness, ultimately contributing to more efficient rehabilitation plans in the future.
This study aimed to determine differences in functional recovery after total hip arthroplasty between a group of patients operated on using a direct lateral approach, an anterolateral minimally invasive approach, and a posterior approach to the hip joint. Arthroplasty is the most commonly performed surgical procedure in orthopedics and is also considered the gold standard for treating the final stage of osteoarthritis. There are several different approaches, but there are still conflicting studies that talk about the benefits of a particular approach. There is an insufficient number of scientific, prospective studies that monitor the basic functional and rehabilitation parameters, which are also indicators of the success of the performed procedure.
The aim of this study is to evaluate Virtual reality (VR) on perioperative anxiety, pain, hemodynamics, and stress hormones in patients undergoing Total hip arthroplasty (THA).
Total hip arthroplasty (THA) is the mainstay, definitive management for end-stage hip osteoarthritis. Despite improvements of surgical and patient factors, prosthesis-related complications continue to increase in number. This is contributed to by the greater number of such surgeries being completed, larger proportion of elderly individuals among the population, and younger patient age being offered surgical intervention. Specifically, implant loosening and associated migration, is the pathology most commonly yielding revision surgery. A previous study assessing migration of total hip prostheses found that the greatest degree of migration occurred in the first 2 weeks postoperatively, although implants were considered overall stable 2 year following surgery. Continued evaluation of implant migration at time points further from surgery, specifically at 5 years postoperatively, offers insight into long term complications rates. Assessing implant migration will be completed using various imaging modalities, radiostereometric analysis (RSA) and computed tomography (CT). Comparisons between RSA and CT imaging will allow for greater analysis with regards to characterization of implant migration and associated bony changes. Additionally, an individual's gut microbiome has been shown to correspond to their inflammatory and immune profile. Association between gut microbiome profile and implant migration will be assessed to determine if underlying relationship does exist.
The primary objective of the study is to evaluate the 10-year performance of the MPACT DM cup in the treatment of patients requiring total hip arthroplasty. The primary endpoint is the 10-year life span of the prosthesis according to the Kaplan Meier curve.
Over the years, the use of large diameter femoral heads has become increasingly common in orthopaedics due to the decreased risk of dislocation due to increased jumping distance and range of motion. The history of total hip arthroplasty does not favour large diameter heads, especially as conventional polyethylene has a high risk of wear. The development of hard-on-hard bearings (CoC) with a second generation ceramic material and the introduction of cross-linked PE have led to the reintroduction of this concept. The Mpact 3D Metal MonoCER cup was developed to offer the advantages of accommodating large diameter heads with an external metal cup with a pre-assembled system that avoids the surgical step of insert-cotile coupling.
Aim: To compare the effect of one single dose versus multiple doses of prophylactic antibiotics administered within 24 hours, on the development of PJI in patients with osteoarthritis undergoing primary THA. The study is designed as a cross-over, cluster randomized, non-inferiority trial. All Danish orthopedic surgery departments performing primary THA with the majority being within inclusion criteria will be involved: Based on national quality databases, two-year cohorts of approximately 20,000 primary THAs conducted at all public and private orthopedic departments in Denmark, this includes 36 sites corresponding to a total of 39 departments.
Aim: To compare the effect of one single dose versus multiple doses of prophylactic antibiotics administered within 24 hours, on the development of PJI after surgery in patients undergoing primary THA due to an acute fracture or sequelae of proximal femoral or acetabular fractures. The study is designed as a cross-over, cluster randomized, non-inferiority trial. All Danish orthopedic surgery departments performing primary THA with the majority being within inclusion criteria will be involved: Based on national quality databases, two-year cohorts of approximately 2,000 primary THAs due to a fracture or sequelae to a fracture, conducted at all public and private orthopedic departments in Denmark, this includes 36 sites corresponding to a total of 39 departments.
This prospective longitudinal cohort study aims (1) to identify clinical phenotypes in persons with hip osteoarthritis and after total hip arthroplasty, and (2) to identify prognostic factors for outcomes after total hip arthroplasty.
Replacing diseased hip joints with prosthetic implants in a procedure called total hip arthroplasty (THA) is associated with high rates of patient satisfaction, pain relief, and functional improvement when the implant is appropriately placed. Incorrect implant size or placement may lead to a breadth of negative outcomes, which could result in the need for implant revision. It is difficult to assess the precise orientation of patient hips on the operating table, with one study revealing that only 26% of acetabular cups placed without technological assistance are correctly positioned. Using computer navigation as a guide to achieve optimal implant alignment may improve successful placement rates. The additional incorporation of real-time modeling software may further help realize higher rates of successful implant placement. This study, therefore, aims to investigate a computer navigation system coupled with real-time modeling software to establish the benefit of such technology in the operating room, and further improve positive patient outcomes following THA. We hypothesize that including technological assistance in THAs will yield better patient outcomes compared to surgeries performed freehand.
