Filter by:The purpose of this study is to investigate the incidence and prevalence rates of multiply revised knee arthroplasty patients in Denmark from 1998-2021.
Total knee arthroplasty (TKA), also known as a knee replacement, is a procedure performed to reduce severe pain and improve function of the joint. Managing postoperative pain can be challenging following TKA, and inadequate relief can lead to impaired mobility and persistent opioid use. Adductor canal nerve blocks (ACB), have shown significant benefit in improving postoperative analgesia and patient satisfaction. However, the local anesthetic used currently for these blocks only provides temporary relief that wears off within 24 hours. Liposomal bupivacaine is an extended-release local anesthetic agent that can provide up to 72 hours of pain relief, however it is unclear if its use is also effective in ACBs for knee surgery. The purpose of this study is to determine if liposomal bupivacaine is better than conventional bupivacaine in improving pain control, opioid consumption, and length of stay in patients scheduled for TKA.
Preventing pre-surgical stress can help patients achieve positive outcomes on health and well-being. However, very few patients receive adequate stress relief support prior to a surgical procedure. Provision of education and information about the surgery can be a crucial component of the preoperative experience and is inversely related to levels of preoperative anxiety. However, resource constraints make face-to-face education sessions untenable, given cost considerations and time investment by trained health personnel. Interventions based on mobile health (mHealth) technologies, geared towards increasing familiarity with surgical procedures and hospital environments have been shown to help patients feel informed about possible benefits and risks of available treatment options. mHealth apps and Virtual Reality (VR) can offer patients experience in the perioperative environment that can be helpful in empowering patients and enhancing a more positive experience, while reducing stress. However, available applications focus only on providing informative content, neglecting the importance of patient empowerment with a more robust educational curriculum. According to this, the Software as a Medical Device (SaMD) CARINAE, aims to support patients and caregivers during the whole perioperative process. SaMD CARINAE consists of an mHealth mobile application for patients and caregivers, a Virtual Reality headset for patients, and a web application for healthcare professionals.
The purpose of this study is to compare quadriceps muscle strength, pain, opioid consumption and patient function during the first three months after short-stay total knee replacement between patients treated with short-duration tourniquet knee replacement with the Aquamantys® bipolar sealer versus those treated with the standard of care (tourniquet used throughout the case and no Aquamantys®). By doing this study, investigators hope to learn if short duration tourniquet knee replacement with the Aquamantys® bipolar sealer is more effective than standard of care (tourniquet used throughout the case and no Aquamantys®). The purpose of this study is to compare quadriceps muscle strength, pain, opioid consumption and patient function during the first three months after short-stay total knee replacement between patients treated with short-duration tourniquet knee replacement with the Aquamantys® bipolar sealer versus those treated with the standard of care (tourniquet used throughout the case and no Aquamantys®).
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.
Efficacy and Safety of Acupuncture Treatment as an Adjunctive Therapy After Knee Replacement
Comparison of two unicompartmental knee arthroplasties (UKA), to see if Sigma UKA performs equally good as the Oxford UKA. The study focuses on how well the arthroplasty is fixated to the bone and on the difference in wear of the plastic insert. Finally, the functional outcome after surgery is compared between the two arthroplasties. Hypothesis: H1: The Sigma UKA has an equal migration pattern compared to the Oxford UKA with a follow up of two years - that is, no significant difference in migration between 1-2 years follow-up. H2: The Oxford and Sigma UKA's have comparable polyethylene wear with a follow up of 5 years. H3: The Oxford and Sigma UKA's have comparable patient perceived outcome measures (PROM) and leg extension power (LEP) postoperative. H4: BMD of the proximal tibia does not influence migration of the tibial component
The overall goal of this study is to identify what Physical Therapy care components are associated with the best patient-reported functional outcome after Total Knee Replacement (TKR) surgery. The investigators are specifically looking at outcomes at 6 and 12 months after surgery.
A retrospective, multi-center, cohort study with prospective follow-up and comparison to historical control
This study evaluates the effect of balance circuit in patients with more than one year of postoperative total hip or knee arthroplasty. Patients were randomized between intervention group (IG) (balance exercise circuit ) and control group (CG) (usual routine). The evaluations were conducted by blind examiners.
