Filter by:The purpose of this study is to investigate the role of two-dimensional FEM models obtained from DXA images in the longitudinal assessment of periprosthetic bone, in subjects undergoing hip arthroplasty. Specifically, the study will focus on the joint analysis of changes in the parameters of bone mineral density (BMD) and Bone Strain Index (BSI) at the level of periprosthetic bone of the proximal femur in patients undergoing hip replacement surgery using DXA, evaluating the densitometric variation of these two parameters over time, starting from an immediately postoperative data and checking the change at 6 months to follow the patient through the postoperative course
Aim To investigate the effect of internal fixation versus hip arthroplasty on physical function and pain in elderly patients. Methods This is a substudy of an on-going nationwide multicenter registry-based RCT named HipSTHeR- (Hip Screws or Total Hip replacement or undisplaced femoral neck fracture in elderly patients) [21]. The aim is to recruit 340 patients with undisplaced or minimally displaced femoral neck fracture, Garden 1 or 2, are randomized to surgery either with internal screw fixation or hip arthroplasty. This substudy aims to investigate the potential differences between internal fixation versus hip arthroplasty regarding physical function and pain 4- and 12- months after surgery. Those included in the main study will be contacted by letter a few weeks after the surgery to be invited to participate in a further study. The assessor will then contact the person by telephone to answer further questions and to obtain informed consent. The follow-ups will be conducted over telephone and mail at 4 and 12 months. During the follow-up the participants will answer questions about their functional level. Information on randomisation and fracture data will be acquired from the Swedish Fracture Register and treatment data from the Swedish Hip Arthroplasty Register. Primary outcome The New Mobility Score will be used as the primary outcome with follow-up at 4- and 12 months. Secondary outcome WOMAC will be used as an additional hip specific patient reported outcome. Activities of daily living will be assessed with Katz ADL index to evaluate the patients' performance and the need of assistance in ADL. Patients' cognitive status will be assessed ALFI-MMSE, adapted from Adult Lifestyles and Function Interview (ALFI-MMSE). The Geriatric Depression Scale (GDS-15), which are developed to identify depressive symptoms. The Philadelphia Geriatric Center Morale Scale (PGCMS) and have been used in several studies including frail people living in residential care facilities and can be used among patients with cognitive impairment.
This clinical trial will investigate whether metallic lateralization in reverse shoulder arthroplasty is as stable as bony lateralization during the first two postsurgical years, measured with CT-based motion analysis (CTMA).
Patients presenting with prosthetic joint infections of a total knee replacement who are treated with an antibiotic spacer will be observed prospectively for their response to treatment and antibiotic elution profiles will be measured post-operatively utilizing mass spectrometry from synovial fluid acquired as part of standard of care in the management of prosthetic joint infection. Secondary outcomes including post-operative complications, re-operation rates, and re-admission rates will also be compared.
The purpose of this project is to determine if a change in patient reported pain, nausea and vomiting after total knee arthroplasty can be observed with the substitution of a post operative adductor canal block for a preoperative adductor canal block in the current established peri-operative pain protocol and if these changes lead to a decrease in opioid consumption (in morphine equivalents).
The goal of this clinical trial is to observe the impact of a surgeon-driven bone health referral pathway following lower extremity arthroplasty. The main question this study aims to answer is: 1) What is impact of a surgeon-driven bone health referral pathway on implant-related complications and fragility fractures when compared to standard of care primary care provider referral. Researchers will compare the endocrinology referral pathway and standard of care to see if there is a difference in treatment rates, fragility fractures, and implant-related complications following lower extremity arthroplasty.
This research aims to develop an optimal physiotherapy intervention for people with arthrofibrosis (stiffness due to scar tissue) after total knee replacement (TKR). We will develop an optimal intervention by conducting: 1. A review of the evidence to identify what components could be included in the intervention, how effective they are and what outcomes have been measured by the research. 2. Interviews with patients with arthrofibrosis to understand the impact it has on their life and what outcomes are important to them and interviews with healthcare professionals (HCPs) to understand their experiences of treating patients with arthrofibrosis. 3. A Delphi study with a larger group of HCPs and patients to reach a consensus on what the optimal intervention should include. This involves a series of anonymous voting on a range of items that have been generated by the group and the results of the evidence review. 4. A workshop with patients, HCPs and health-care commissioners to finalise the intervention. During the workshop we will present our findings and work in small groups to agree the intervention
The functional evaluation of the shoulder, which is the most mobile joint in the human body, is a complex clinical examination to perform. The mobility of the shoulder is based on a three-dimensional mobility cone, which is difficult to represent and measure. However, an accurate and reliable measurement of the shoulder's articular amplitude is fundamental for its functional evaluation. Indeed, these measurements contribute to determine the global management strategy of the patient and the follow-up of its evolution. The conventional method of measuring shoulder joint amplitudes involves the use of a goniometer. Nevertheless, visual estimation is the most used in consultation but is limited by its very examiner-dependent character. Technological advances have allowed the development and deployment of additional tools in the clinical setting, with the goal of simplifying, reducing measurement bias, and standardizing joint range of motion (ROM) measurement techniques. Our team has recently published a study to validate the use of a joint ROM measurement system, coupling a RGB-D (Red Green Blue - Depth) sensor and an artificial intelligence (AI) algorithm, on volunteer subjects with no shoulder history. The RGB-D camera is a technological tool in high development and low cost. It consists of two sensors, an infrared projector and an RGB module. The camera simultaneously provides a two-dimensional (2D) image and its environment by creating a color flow using infrared technology combined with a depth map characterizing the distance of objects seen in the image. The AI algorithm then automatically detects a 2D skeleton that identifies the main joints of the upper limb (shoulder, elbow, wrist) and the trunk axis. Then, the angle of interest is measured and each mobility is automatically measured in 3D by the algorithm. The main objective of the study is to validate and demonstrate the feasibility in clinical practice and the concordance of an automated RGB-D + AI system for the measurement of shoulder joint ROMs of patients having undergone reverse total shoulder replacement surgery. These measurements will be compared with the visual method and the goniometer, that are measurements made in normal care routine. The ROM measures obtained by means of the RGB-D + AI system will be compared to those obtained in clinical practice during the annual follow-up visit in normal care routine. The main evaluation criterion is the measurement of joint amplitude measured in degrees [°]. The ROMs that will be measured are those normally assessed in clinical practice: abduction-adduction, flexion-extension and external-internal rotation elbow to body or at 90°. This study aims also at observing and comparing the postoperative joint ROM measurements estimated in the preoperative planning phase by the Blue-Print software with the actual postoperative ROM measured with the RGB-D + AI system. The study is observational. The processing of the collected data does not foresee any intervention on the patient or modification of the surgeon's choice concerning the management of the patient. It is indeed a RNIPH (Recherche non impliquant la personne humaine).
Residual limping after total hip arthroplasty is empirically associated with the use of lateral approach but has been reported in litterature even with the use of posterior approach. The purpose of this clinical trial is to compare the risk of residual limping one year after total hip arthropasty between lateral and posterior approach.
Patient-reported Outcome Measures (PROMs) used in total knee arthroplasty focus more on quality of life and pain. For this reason, individuals who can perform activities of daily living normally can get full points. There is a need for PROMs used in the assessment of higher functional skills. This study aimed to translate The High-Activity Arthroplasty Score (HAAS) into Turkish and to conduct a validity and reliability study of the Turkish version.
