The pain and severe wear of hip joints caused by osteoarthritis, rheumatoid arthritis, avascular necrosis and trauma can be subjected to total hip replacement (THR). A hip implant consists of 4 components: acetabular cup, femoral stem, articular liner and femoral head. As an ideal material for THR, ceramic possesses excellent biocompatibility and stability in the human bodies. Moreover, ceramic-on-ceramic interface is highly wear-resistant, preventing generation of wear particles. With the development of latest fourth-generation ceramic Delta, larger femoral heads can be manufactured to conform to the size of native femoral heads. The rate of some of the complications after THR, such as dislocation, can be significantly reduced. The purpose of the present study is to carry out a clinical follow up for each patient who has received the ceramic-on-ceramic THR in order to understand the clinical outcome. Furthermore, the possible complications, such as dislocation and squeaking, can be determined.
The objective of this study was to evaluate the effects of an enhanced recovery after surgery (ERAS) pathway incorporated with pre-operative physical therapy and education on immediate and short-term outcomes of minimally-invasive surgery of total hip arthroplasty (MIS-THA). We hypothesized that this ERAS pathway can shorten post-operative length of hospital stay and ensure same-day independent mobilization in MIS-THA. The first specific aim was to compare primary immediate outcomes, including post-operative length of hospital stay and the rate of same-day independent mobilization, between ERAS for MIS-THA patients and conventional MIS-THA patients. The second aim was to compare other immediate outcomes, including post-operative pain scores, analgesics usage, the rate of blood transfusion and post-operative nausea and vomiting (PONV), between the two groups of patients. Third, we aimed to compare short-term outcomes, including post-operative 1-year Harris hip score, Oxford hip score and EQ-5D index of quality of life, between the two groups of patients. We also compared hospital cost and profit between the two groups of patients. Moreover, we identified the factors affecting post-operative length of hospital stay in ERAS for MIS-THA patients.
Objective: The main objective of this study is to compare the (early) migration of the cemented BiMobile cup at two year post-surgery between two different cup sizes after standard optimal reaming, and consequently adjusting the cement mantle into circa 2 or 4 mm, in patients with a primary cemented total hip arthroplasty (THA). Additionally, the results of the BiMobile cup will be compared to the Avantage cup, which is placed with a standard cup size, resulting in a cement mantle of approximately 2 mm. Study design: A prospective single centre blinded randomised controlled trial. Study population: All patients who meet the criteria to undergo a cemented THA.
Objective: The primary objective is to investigate whether there is a difference in the number of hip dislocations following primary total hip arthroplasty (THA), using the posterolateral approach, with a DM cup compared to a unipolar cup in elderly patients 1 year after surgery. Study design: Prospective multi-center nation wide, single blinded RCT nested in the LROI. Study population: Patients ≥ 70 years old, undergoing an elective primary cemented THA.
This is a retrospective chart review to determine if neuraxial anesthesia is associated with worse outcomes after Primary Total Hip Arthroplasty.
Currently there is no consensus on the optimal peripheral nerve block for Total Hip Arthroplasty (THA). Furthermore, there is a gap in the literature in regard to the efficacy of Quadratus Lumborum Block (QLB) for Total Hip Arthroplasty via posterior approach. This Randomised Controlled Trial aims to examine the effectiveness of anterior QLB in patients undergoing Total Hip Arthroplasty via posterior approach. The investigators hypothesise that anterior QLB and spinal anaesthesia is superior to spinal anaesthesia alone with reference to analgesic efficacy and functional ability to engage with physiotherapy in the first 24 hours postoperatively.
Total hip arthroplasty (THA) is associated with blood loss ranging from 300 to 2000 mL. Tranexamic acid (TXA) is frequently administered prophylactically during this procedure to reduce blood loss by inhibiting fibrinolysis or by stopping naturally occurring clot resolution. TXA is employed currently based on a surgeon's preference. The objective of this study is to quantitate the degree of fibrinolysis using rotational thromboelastometry (ROTEM) and investigate the role of TXA prophylaxis on blood loss in patients undergoing THA in a double-blind fashion. Our hypothesis is that fibrinolysis is minimal at most and TXA prophylaxis is not necessary during THA. All patients, whether they receive TXA or normal saline, will not be at risk, as at this time no data exists to determine which approach is safer or more effective. This is the first study to compare TXA vs. placebo in a double-blinded, randomized controlled trial.
This is a retrospective and prospective, multi-center, post-market clinical follow-up study involving orthopedic surgeons skilled in THA and experienced implanting the study device system.
Osteoarthritis is one of the most common chronic diseases of the musculoskeletal system in elderly. Patients with osteoarthritis experience pain, stiffness and loss of mobility. Due to ageing Western societies in the coming decades the number of elderly with osteoarthritis will progressively increase. Osteoarthritis is a common indicator for a Total Hip Arthroplasty (THA). A hip replacement is one of the most successful orthopedic surgeries. However, with regard to the postoperative rehabilitation a lot can be improved. The current situation after a THA is that physical therapy in the Netherlands is not prescribed by default. Patients are resigned from the hospital and receive home exercises. However, it is not clear whether patients actually carry out these exercises and whether they perform the exercises correctly.
