Opioid-free Total Hip Arthroplasty
Hip OsteoarthritisThe primary objective of investigators' proposed study is to demonstrate that the following two cohorts undergoing total hip arthroplasty will have equivalent visual analog scale (VAS) scores up to 3 months post-operatively: one that is administered a modified multimodal analgesic pathway without opioids and the other administered the current standard multimodal analgesic pathway used at Johns Hopkins Bayview Hospital (which includes opioids). The secondary objective is to demonstrate that these cohorts will also have equivalent functional outcomes as determined by both objective measures (such as hip range of motion) and patient-reported outcome measures, such as the Hip Disability and Osteoarthritis Outcome Score (HOOS) and the University of California at Los Angeles (UCLA) activity score.
Effects of Denosumab on Periprosthetic Bone After Total Hip Arthroplasty
OsteoarthritisHip1 moreThe primary objective is to study the effect of Denosumab on Bone Mineral Density, Standardised Uptake Value and bone metabolism in patients with total hip arthroplasty. The primary hypothesis is to demonstrate that Denosumab is superior to placebo.
Diagnostic Performance of 3T MRI T2 Mapping Technique in Chondro-labral Pathology of the Hip, Correlated...
Hip Injuries and DisordersHip ArthrosisThe goal of this observational study is to evaluate the diagnostic performance of the T2 mapping technique of the following 4 MRI scans in detecting hip chondro-labral lesions in comparison with intraoperative arthroscopic findings: 1) basal 3T MRI with T2 mapping technique, 2) 3T MRI with T2 mapping technique and limb traction; 3) 3T arthro-MRI with T2 mapping technique; 4) 3T arthro-MRI with T2 mapping technique and limb traction.
Stability of Revision Total Hip Arthroplasty Implants Using Radiostereometric Analysis
Osteoarthritis of HipFailure of Primary THAThe specific aim is to quantify the stability of the acetabular and femoral components of a revision total hip arthroplasty (THA) in vivo as currently performed at our institution. In this way, the investigators will gain insight into the outcome of the current state of the art of revision arthroplasty surgery. In the past, acetabular and femoral component stability has been measured using radiostereometric analysis (RSA) and when patients having revision total hip operations were compared to patients undergoing primary total hip operations it was possible to determine differences in stability and this was predictive of the intermediate to long-term performance of the acetabular and femoral reconstruction. The investigators propose to use this established, high resolution technique to assess and compare the stability of the revision implants.
Robotic Total Hip Arthroplasty Anesthesia Management
Hip OsteoarthritisJoint Diseases1 moreRobotic arthroplasty is increasing in acceptance on a global scale as a result of advancements in orthopedic surgery technology. The investigators aimed to share their anesthesia management experience as well as compare robotic unilateral total hip arthroplasty with conventional surgical technique in this retrospective study.
Study to Evaluate Arthroplasty Specimens for Osteoarthritis of the Knee and Hip
OsteoarthritisKnee2 moreThe objective of this exploratory study is to evaluate the cellular and connective tissue composition of joints from patients with Osteoarthritis (OA) who have been treated with fasinumab, compared with those treated with placebo or Non-steroidal anti-inflammatory drugs (NSAIDs).

RCT Measuring the Effect of the ERVIN Software
Decision MakingShared11 moreThe randomised clinical trial investigates the effect of using a clinical decision support system (CDSS) aiming to provide the patients and surgeons with greater transparency concerning the obtainable changes in function and health related quality of life (HRQoL) when patients are to decide if they should undergo hip- or knee replacement surgery.
Development of an Effective Home-based-exercise-strategy
OsteoarthritisHip1 moreOsteoarthritis 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.
Comparative Effectiveness of Decision Support Strategies for Joint Replacement Surgery
Hip OsteoarthritisKnee OsteoarthritisThis study is a 2X2 factorial randomized trial that will the examine the comparative effectiveness of two patient decision aids for hip and knee osteoarthritis (OA) as well as the impact of a surgeon-focused intervention.
