Filter by:Retrospective observational study: impact of a peri-operative patient blood management program (PBM) on transfusion rates of patients undergoing elective hip replacement.
Preoperative rehabilitation before total knee arthroplasty (TKA) has not been proven to be effective. Latest meta-analyzes do not find any improvement of motor performance during gait 6 months after surgery. However, most of the previous studies did not specifically target muscle atrophy to design rehabilitation protocol. Pre-operative muscle atrophy, although not systematic, is often observed. The preoperative muscles volumes of thigh muscles have been poorly identified and never used to adjust the pre operative rehabilitation strategy. As part of the "FOLLOWKNEE" (RHU) project, which attempts to implement a personalized management of TKA and its follow-up, this study wants to explore the potential effect of adapted treatment to improve muscle force and muscle volume before TKA.
The purpose of the study is to assess the accuracy of Butterfly IQ ultrasound for intra-articular hip injections, and to see if an injection given intra-articular before incision provides any benefit in preemptive pain relief or blood loss reduction.
This investigation is a prospective, multi-center clinical investigation. It is anticipated that a total of one hundred (100) subjects will be enrolled at approximately 5-10 sites. The clinical investigation has been designed to follow the surgeon's standard of care for joint arthroplasty patients, which entails clinical evaluation on a regular ongoing basis, or as needed should the patient become symptomatic in the treated joint.
A prospective multicentre randomised clinical trial of 250 selected patients with THA, who will be randomly assigned to intervention (IG) or control group (CG). Both will have standard physiotherapy during hospitalisation, IG will additionally learn strength and sensory-motor training exercises. Follow up will be performed with physical tests, maximal voluntary isometric contractions and outcome assessment questionnaires at baseline and 1, 3 and 12 months after surgery.
Hip arthroplasty is a treatment widely used in most inflammatory, traumatic and degenerative conditions of this joint. The longevity of implants may be disappointing in some cases, despite the promising results obtained during in vitro simulations. Early loco-regional or systemic dissemination, known since the 1990s, of wear particles from these prosthesis may reduce their life span. The analysis of the particles in the synovial fluid and in the articular tissues by electron microscopy after digestion or directly by optical microscopy, will improve the knowledge on the mechanisms of wear. This category 3 study is based on the case-control model and will be conducted in a national reference center (hospital la Croix-Rousse- Lyon). It will include a population of adult patients.
The hypothesis of this study is that there are people running following a total knee arthroplasty (TKA). The objective is (1) to determine if there are people that ran/run following their TKA and (2), in case (1) is true, to identify some general running parameters such as duration, frequency, perceived barriers for running. Patients with a TKA and a score equal or higher than 9 on the UCLA activity scale at any time between 2 years prior to surgery and at present will be invited to participate in the trial by phone. All these patients will receive the study's information form and questionnaire by post with a pre-stamped envelope to return the documents.The survey was created and piloted internally for this study. There are 21 questions, most of them are "yes or no" and some others open questions to assess parameters such as duration of difficulties faced. The questionnaire is composed of three parts. The first part is interested in the preoperative activity (during the 2 years before surgery), the second part in the postoperative activity (during the 2 years after surgery) and the third part refers to the current practice. For each part, people are asked about specific practice parameters and modalities. Furthermore, we seek to determine whether there was/is a willingness to run following TKA, if patients receive any education/information about it and their personal attitudes towards running with a TKA. The anonymized data will be collected by the main author for subsequent analysis.
This is an observational, prospective study that has the primary goal of validating the Forgotten Joint Score (FJS)
The main objective of this pilot study is to determine if using a portable, accelerometer based, visual feedback system improves exercise quality. The secondary objective of this study is to investigate the effect of motivational targets by testing the effects of increasing ROM targets. The results from this study will be used to improve the visual feedback system of the Knee Connect system and serve as starting point for a larger clinical study.
The purpose of this study is to assess the effectiveness of a preoperative muscle training program on hip or knee TJA (Total Joint Arthroplasty). It aims to improve hospital discharge readiness and functional capacity in both the short and long-term. One of the key factors affecting recovery after TJA is how well the patient functions before their surgery. Thus, interventions addressing preoperative function are expected to be beneficial.
