The Metaphyseal Hip Prosthesis - Total Hip
Osteoarthritis of the HipThe purpose of this study is to analyze stability, safety and efficacy of the Metaphyseal Hip Prosthesis (MHP) compared to the Stanmore hip replacement.
A Comparative Study of Stem and Cup Fixation and Polyethylene Wear
OsteoarthritisHipA randomized controlled study comparing two types of cementless femoral stems (LCU and Corail) and two types of acetabular components (DeltaTT and Pinnacle Duofix) in primary total hip arthroplasty. Primary outcome are component migration measured by RSA, wear and patient reported outcome. Patients are evaluated up to 15 years postoperatively.
Progressive Resistance Training Versus Total Hip Arthroplasty in Patients With Hip Osteoarthritis...
Hip OsteoarthritisHip osteoarthritis is associated with joint pain, physical disability, decreased muscle strength and poor health status, and the most common cause for total hip arthroplasty. No studies have investigated the effect of total hip arthroplasty compared to non-surgical treatment in patients with end-stage hip osteoarthritis. This comparison is of upmost importance as it is unknown whether non-surgical treatment may be used as an alternate to surgery. The purpose of this study is to investigate whether total hip arthroplasty followed by standard care is superior to progressive resistance training for improving hip function and pain in patients with end-stage hip osteoarthritis. The hypothesis is that patients treated with total hip arthroplasty will improve more than patients treated with progressive resistance training.
Fitmore Versus CLS Stem in Total Hip Arthroplasty. Bilateral One-stage Operations
Primary Hip OsteoarthritisSecondary Hip Osteoarthritis Due to Idiopathic Femoral Head Necrosis3 moreMain question: Will use of a stem design that allows anatomical reconstruction of the hip joint improve the outcome in terms of hip function and patient satisfaction without causing any adverse effects? Background: Total hip arthroplasty with use of the most well documented implants is a safe and cost-effective procedure. In the Swedish Hip Arthroplasty register the CLS stem has a 16 years implant survival of 97, 5 %. It is a classic design which requires resection of most of the neck. The stem also intrudes into the greater trochanter which in patients with certain types of proximal hip anatomy makes proper introduction of the stem difficult. Finally it has a standard stem length which will jeopardise future stem removal should there occur any late infection or instability problems. Short uncemented stems have been introduced to enable a more anatomic reconstruction of the hip joint and to cause less invasion of the femoral canal to facilitate future revision should it be necessary. A more conservative resection of neck could also be of value to improve the clinical outcome by improved hip function and patient satisfaction. Purpose of the present study and design: In a prospective study the clinical outcome, stem fixation and bone remodelling around a short stem (Fitmore) will be studied. The main focus will be to evaluate patient reported outcomes especially concerning function, over all satisfaction, pain and activity. All patients will receive the same cup (Trilogy). This cup is chosen because it has a very thorough documentation in prospective RSA studies and in the Swedish hip arthroplasty register. All cups will be supplied with insert made of high molecular polyethylene (Longevity). Number of hips in the study: 44 consecutive cases
Multicenter Study for Robotic Arm-assisted THA 4.0 System: Hip Spine Relationship
OsteoarthritisHip1 moreThe current study is a multi-center study to assess precision and accuracy of the robotic system with new software.
Assessment of Polyethylene Wear, Migration and Clinical Outcome in Total Hip Replacement
OsteoarthritisHip1 moreThe objective of the study is to investigate head penetration, cup migration, and clinical outcome in total hip replacements using a factorial design. Treatment groups are E-Poly versus ArComXL liners, and 36 mm versus 32 mm head size.
Selecting the Right Hip Prosthesis for Young Patients
OsteoarthritisHipThere have been no previously published clinical randomized studies comparing Primoris®, short stem, hip prosthesis with standard uncemented hip arthroplasty in relation to bone density and function development. This is the subject for this study.
REDAPT Revision Hip System With RSA
Hip OsteoarthritisThe principal objectives of the study are to evaluate early and mid-term fixation of the REDAPT revision hip stem and acetabular cup as measured by stem subsidence and proximal cup migration at 2 and 5 years post-surgery through model-based RSA. Secondary objectives include; evaluate the progression of migration between 1 and 2 years and between 2 and 5 years, assess pre- to post-surgery patient improvement in function and health status, evaluate femoral and acetabular radiolucency at 2 and 5 years, and assess patterns of stem migrate on for different revision scenarios (preservation of the trochanters and extended trochanteric osteotomy).
Conventional Total Hip Arthroplasty vs Mako Robotic-arm Assisted Total Hip Arthroplasty
OsteoarthritisHip2 moreThe overall aim of this single-centre, prospective randomised controlled trial is to compare clinical, functional, and radiological outcomes in CO THA versus Mako THA. Patients undergoing Mako THA will form the investigation group and those undergoing CO THA will form the control group.
OA Optimization Program Pilot Trial
Osteo Arthritis KneeOsteoarthritis4 moreTotal joint replacement is a highly successful treatment option for people affected by severe osteoarthritis (OA), however, the mismatch between resources and demand for this surgery means that many patients face long wait times while enduring worsening pain and disability. The Alberta Hip and Knee Program is a centralized intake system for patients referred for total joint replacement assessment. Over 3000 patients are assessed annually at the Calgary location (Alberta Hip and Knee Clinic at Gulf Canada Square) where previously patients waited an average of 43 weeks for a surgical consult then an additional 30 weeks until surgery. Given that many elective surgeries in Alberta have been cancelled in response to the COVID19 pandemic, these wait times have increased significantly, with no clearing of the surgical backlog for the foreseeable future. Long wait times for patients can become a spiral of more debility, less mobility, and subsequent weight gain. The current standard of care for patients with obesity awaiting surgery provides little support or guidance beyond general advice about the importance of a healthy weight and remaining active. This waiting period represents an untapped window of opportunity to intervene and help patients with obesity and OA to lessen their disease burden and improve overall health, while addressing patient priorities such as regaining lost function and improving quality of life. Many patients with osteoarthritis also have obesity. The best practices in obesity treatment requires a multidisciplinary approach. Our aim is to conduct a pilot randomized controlled trial (RCT) to evaluate the feasibility of incorporating the multidisciplinary Alberta Obesity Centre program into the clinical care pathway for patients with obesity and OA while they await surgical evaluation at the Alberta Hip and Knee Clinic at Gulf Canada Square. The results of this feasibility trial will help inform a larger scale trial that will be powered for clinical and health economics outcomes.
