Osteoarthritis, Hip

his study will test whether giving dexamethasone through a vein can improve pain control after total hip replacement surgery. Dexamethasone is commonly used to reduce nausea and may also help with pain, but it is not clear which dose works best. Patients will be randomly assigned to receive either no dexamethasone, 4 mg, or 8 mg, in addition to standard anesthesia and a nerve block (PENG block). The main goal is to see how long patients go without needing additional pain medication after surgery. The study will also look at pain levels, use of opioid painkillers, nausea and vomiting, blood sugar levels, and possible side effects.

This study aims to investigate whether oral cannabis extracts can effectively manage pain caused by osteoarthritis (OA), a common joint condition affecting one in seven Canadians. Current OA treatments often have limited effectiveness and may cause side effects. As a result, many individuals with OA turn to medical cannabis for pain relief, despite limited scientific evidence supporting its efficacy. The goal of this study is to assess the feasibility of a larger trial evaluating the effects of two cannabis compounds-CBD and THC-compared to a placebo (a look-alike substance containing no active drug) on pain interference in patients with hip and/or knee osteoarthritis. Participants will: * Take either CBD, THC, or a placebo capsule daily for 8 weeks * Complete follow-ups remotely, with no in-person clinic visits required * Maintain a diary tracking their study drug usage and any additional pain medications

The goal of this clinical trial is to determine the effect of Resistance Exercise Training (RET)-based (p)rehabilitation versus usual care on skeletal muscle mass and function, as well as on underlying biological processes, in older adults undergoing elective Total Hip Replacement (THR) due to severe Osteoarthritis (OA). The main questions it aims to answer are: * What is the effects of RET-based (p)rehabilitation versus usual care to improve muscle mass and function in patients undergoing elective unilateral THR surgery for end-stage OA? * What is the potential of certain circulating biomarkers to predict the efficacy of the musculoskeletal system response to RET in patients with severe OA? Researchers will compare RET-based (p)rehabilitation versus usual care to see if RET works to increase skeletal muscle mass and function. Participants in the usual care group will undergo standard rehabilitation (12 weeks post-surgery), and participants in the (p)rehabilitation group will undergo RET-based full-body (p)rehabilitation (3x/week) for 2 weeks pre-surgery and 12 weeks post-surgery.

The study aims to assess the adequacy of a set of clinical and laboratory investigations for identifying the osteosarcopenia status in patients undergoing a hip replacement for a fragility fracture of the femoral neck. The control group will consist of patients undergoing a hip replacement for osteoarthritis, as the decrease in muscle function and bone quality is less severe in this condition than in osteoporosis.

The purpose of this study is to determine if the use of the HIT Reverse Hip Replacement System is safe and effective in patients undergoing total hip replacement. We will determine whether it is safe and effective by comparing it to the control devices.

PROSAP-A is a perioperative randomized, controlled trial with a 12-month follow-up period after total knee arthroplasty (TKA) or total hip arthroplasty (THA), aiming to investigate both acute and long-term postoperative effects of preoperative sleep-promotion. Participants with clinically significant insomnia symptoms will be randomized to a brief, hybrid version of cognitive behavioral therapy for insomnia (CBT-I) or sleep education therapy, administered over a 4-week period, prior to surgery. The primary objective is to evaluate effects of preoperative sleep-promotion on acute postoperative pain control. Secondary objectives include evaluation of postoperative sleep, recovery, mental health, cognitive function and alterations in blood biomarkers.

Bone marrow samples will be collected from patients undergoing hip arthroplasty surgery. Blood and bone marrow samples will be used for metabolic profiling and analysis of relevant CHIP mutations. Combined single-cell transcriptomics and mutation-specific single-cell genotyping (biotin-PCR using mutation-targeted primers followed by sequencing) will subsequently be performed. The gene expression profile of wildtype and mutant hematopoietic stem cells will be compared, performing both broad gene set enrichment analysis and targeted analysis of metabolic pathways.

This PMCF study is designed to collect safety and efficacy data on hip hemiarthroplasty surgeries with Corin BiPolar-i shell and the Oceane+ or Meije Duo femoral stem up to 10 years.

Choose to Move (CTM) is a 3-month, choice-based health-promoting program for low active older adults being scaled-up across British Columbia (BC), Canada. Recently, the investigators adapted CTM for the \>14000 people in BC who are on surgical waitlists for total knee replacement or total hip replacement (TKR/THR) for osteoarthritis (OA). The primary goal of this observational study is to learn if the adapted program, Choose to Move Replacement Ready (CTM-RR), is feasible to deliver to people with hip and/or knee osteoarthritis who are on surgical waitlists for TKR/THR. Participants who enrol in CTM-RR will answer online survey questions about the program and about their physical activity, mobility, pain, function, quality of life, willingness to undergo surgery, overall perception of their joint condition, psychosocial health, self-efficacy, social isolation, loneliness, and sedentary time. CTM-RR activity coaches will also answer online survey questions about the program. CTM-RR participants, activity coaches, and referral partners will also participate in interviews about the program.

This prospective randomized clinical study aims to evaluate the effects of different suture materials and wound closure techniques on wound healing, functional outcomes, and postoperative complications in patients undergoing total hip and knee arthroplasty. A total of at least 90 adult patients undergoing primary or aseptic revision lower extremity arthroplasty will be randomized into two groups according to the wound closure material and technique used. All surgeries will be performed by the same surgical team following standardized operative protocols. Primary outcomes include wound-related complications such as prolonged wound drainage, wound dehiscence, surgical site infection, and local inflammatory findings within 90 days postoperatively. Secondary outcomes include operative time, bleeding amount, cosmetic outcomes, and functional scores. The results of this study are expected to help determine the most effective and safe wound closure method in lower extremity arthroplasty.

The goal of this interventional post-market follow-up study is to evaluate radiological changes in the diaphyseal bone density (Gruen Zones 3 and 4) within 24 months postoperative in patients treated with CoreHip® primary cementless stem. The DEXA bone density analysis is used.

There is a lack of effective analgesic treatments to help walking patients with painful hip/knee osteoarthritis. Our team therefore imagined a new strategy lying on a multimodal rehabilitation walking program with the help of a transient intake of nonsteroidal anti-inflammatory drug (NSAID). NSAIDs are indeed known to act specifically on pain at movement, but their continuous intake would induce unacceptable side effects. To optimize the benefit/risk balance, the molecule to be chosen must fit to the patient's profile, and its intake should cover only the period of interest, i.e. planned walks. Our multimodal rehabilitation program will also include physical techniques such as appropriate footwear, a patient's education aiming at reducing fear/avoidance and spotting side effects of NSAIDs, and a prescription frame to avoid any overdosing. This clinical study is a single-center, non-randomized, open label, one-arm trial, using drugs prescribed according to their label (i.e. osteoarthritis pain), pending a reinforced monitoring of side effects. The primary endpoint is to evaluate efficacy and tolerance of a tailored and transient administration of NSAID within a rehabilitation walking program in patients with painful hip/knee osteoarthritis. Secondary endpoints are to evaluate the adherence to the program and the factors influencing adherence; to identify the less well tolerated conditions of treatment (one condition being one molecule for one patient profile); to identify the factors of success among a set of baseline demographic, morphometric and psychometric variables; and to study the role of central sensitization (assessed by temporal summation) on the efficacy of treatment.

Any patient aged 14 or older up to 64 years of age with hip disease, resulting in loss of articular cartilage integrity on the femoral head (e.g., femoroacetabular impingement or other structural deformity), has failed conservative care, and is a candidate for surgical intervention to treat.

The primary objective of this study is to study how low-impact group exercise classes affect pain scores in patients with knee, hip, and ankle pain when paired with concurrent standard of care dietitian and behavioral health consults.

Multicenter, independent study of Synolis VA 80/160 over a period of 6 months

The purpose of this study is to cast light on the highly complex etiology and cellular landscape of hip osteoarthritis by utilising single-cell and spatial omics.

In this work the investigators will study the relationship between chronic musculoskeletal pain and abnormal blood flow (neovascularity) around the shoulder, hip and knee. Veterans with as history of chronic shoulder, hip or knee pain and mild/moderate joint degenerative changes will be potential study subjects. Blood flow around joints will be evaluated using perfusion magnetic resonance imaging (MRI). Participants with demonstrably abnormal blood flow around their painful joint will be eligible for enrollment in a pilot study of joint embolization to treat their pain. Participants who choose to not undergo treatment will be re-assessed with MRI after one year to characterize the natural history of joint neovascularity and its relationship to pain.

This study will compare postoperative pain, health related quality of life (HRQoL), function, rehabilitation, urinary incontinence, muscle atrophy and component positioning in total hip arthroplasty (THA) using the posterolateral approach (PLA) or the direct superior approach (DSA). In addition, the CT images will be used to validate a new metal artefact reduction technique.

Total hip replacement is the most successful treatment modern healthcare can offer patients to regain quality of life. Periprosthetic joint infection (PJI) is the most common and devastating complication after total hip replacement (THR). Between 0.5 to 2% of primary THR (first time hip replacement), and 8-10% of revision THR (replacement of a hip prosthesis) will become infected.1 The introduction of local antibiotics blended into bone cement has led to a reduction in postoperative infection in primary THR by half.2 Unfortunately, cement can't always be used in relevant quantities. The number of primary and revision surgeries of the hip is projected to increase dramatically. Therefore, the need for a feasible infection prophylaxis that is applicable for complex primary and revision THR in addition to antibiotics loaded cement is urgent. Impacted morselized bone allograft is often used in (revision) THR to fill bone defects. Morselized allograft has been used as a carrier for local antibiotic treatment in multiple pilot studies and appears to be an attractive and effective treatment option, both for already infected joints and as a prophylactic measure in high-risk patients (e.g. THR revision surgeries). Nonetheless, a pivotal trial to support its use in THR is lacking. The aim of this pragmatic randomized controlled double blinded drug trial is to investigate whether antibiotic impregnated bone graft (AIBG) decreases the risk of infection after hip arthroplasty compared to controls treated with placebo impregnated bone graft. Patients scheduled for elective THR will be randomized to receive AIBG or a placebo impregnated bone graft. The primary outcome variable will be the number of re-operations due to infections and PJI diagnoses 2 years postoperative.

Total hip arthroplasty (THA) is a common surgery that eases pain, restores functional movement, and improves the overall quality of life in people with severe hip osteoarthritis (OA). Unfortunately, problems with postural stability, commonly known as balance, are still noticed in people even years after the surgery. These postural stability problems typically result in falls. The aim of the proposed study is to investigate how THA surgery affects a person's overall quality of life, both physically and psychologically, in terms of postural stability and balance confidence (self-efficacy) within the first three months after THA for osteoarthritis. This prospective cohort study will focus on people over 60 years old.

The main objectives of this study are to confirm the long-term safety, performance, and clinical benefits of the G7 Acetabular Shells when used with the Vivacit-E and Longevity HXLPE liners and instrumentation in primary and revision total hip arthroplasty.

The overall aim of this study is to compare three different care models for patients with hip- and knee osteoarthritis. The primary aim is to evaluate whether an app-based care model is more beneficial for improving function in daily life than a web-based care model and standard care for patients with hip and / or knee osteoarthritis

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.

The goal of this clinical trial is to evaluate the effect of treatment with colchicine 0.5mg once daily as compared to placebo in patients with knee or hip osteoarthritis on the incidence of first occurrence of knee or hip replacement. The main question it aims to answer is: Does colchicine lower the number of knee or hip replacements in participants with osteoarthritis? Researchers will compare colchicine to a placebo (a look-alike substance that contains no drug) to see if colchicine works to treat osteoarthritis. Participants will: * take colchicine every day for 3 tot 4.5 years * visit the clinic every year for check-up and tests such as blood samples and x-rays * fill in questionnaires every 3 months
