Filter by:In the US, if you get an infection in your artificial knee joint that doesn't heal with antibiotics alone, the standard treatment is a two-stage revision of the artificial knee. In the first stage, your surgeon will remove your artificial knee and clean out the area around the knee. They will then place an antibiotic spacer. An antibiotic spacer is a type of artificial joint that will release antibiotics in to the knee space continuously over time. The spacer allows only very basic function of the knee. You may need to use crutches or a walker while the antibiotic spacer is in place. After surgery to place the antibiotic spacer, your surgeon may prescribe a course of antibiotics as well. Because the antibiotic spacer is not as durable as a regular artificial joint, after the infection is gone, another surgery is required to take the spacer out and put a new artificial knee joint in. There is another way for artificial joint infections to be treated. This is a one-stage revision. In this treatment, the surgeon will remove your artificial knee and clean out the area around the knee. Then they will place a new artificial knee in using a special kind of cement that contains antibiotics. The cement will release antibiotics in to the knee space continuously over time (your surgeon may prescribe a course of antibiotics as well). The new artificial joint with antibiotic cement will function almost the same as your original artificial knee. This means that while the infection is healing you will be able to do most of your regular daily activities. However, the antibiotic cement is not as durable as what is normally used to implant an artificial knee. The artificial knee with the antibiotic cement may need to be replaced with a regular artificial knee. When replacement will need to be done is dependent on your weight, bone strength and activity level, among other things. When it is time to replace the antibiotic cement artificial knee, you will have another surgery where the surgeon will take the antibiotic cement artificial knee and but a new artificial knee joint in. We know that both the one- and two-stage revision work equally well to heal the infection, but we don't know which patients prefer or which provides better function after many years. This study will randomly assign patients to receive either a one-stage or two-stage revision and then follow them for 5 years to ask them about pain, function, and satisfaction.
This study is a prospective, double-blind prospective randomized controlled trial comparing mepivacaine and bupivacaine spinal anesthesia for same-day discharge readiness following a unilateral primary elective TKA procedure. Study data will be collected during the patient's hospital stay for their TKA procedure, and the primary outcome of same-day discharge readiness will be assessed the day of surgery. Patients will also be contacted at Day 3 post-op to assess for any complications, current level of pain, and pain medication utilization.
To further improve the surgical outcomes of patients undergoing total knee arthroplasty (TKA). This study aims to use ear acupoint therapy to address the following clinical issues: 1 The degree of postoperative inflammation and edema in the patient; 2. Patient pain; 3. Patient functional recovery. 4. Surgical scar repair for patients; 5. Patient perioperative anxiety and postoperative satisfaction. Exploring the safety and effectiveness of ear acupoint therapy in the postoperative application of TKA, leveraging the advantages of suitable traditional Chinese medicine techniques in simplicity, convenience, effectiveness, and cost-effectiveness, and further improving the ERAS Chinese and Western medicine collaborative plan for TKA.
The goal of this feasibility study is to test the procedures for implementing quality indicator toolkits for hip and knee replacement rehabilitation in clinical settings. The main questions it aims to answer are: - Are the EQUIP (for patients) and QUICK (for clinicians) toolkit resources feasible (accessible, acceptable, usable) in real world clinical settings? - Are study procedures including recruitment and retention, informed consent, clinical site tracking, audit and feedback, training and data collection feasible? - What effect does toolkit implementation have on patient experiences, quality of care and patient-reported outcomes? Participants will be asked to provide consent at time of discharge from rehabilitation to have their clinical records audited and to complete an online questionnaire about their physical function, quality of care they received, and overall rehabilitation experience and satisfaction. Rehabilitation providers will also be asked to complete a questionnaire on their adherence to ten post-acute rehabilitation quality indicators after a 3-month baseline period and 6-month implementation phase.
Knee osteoarthritis is a degenerative joint disease that affects many older adults. However, not all patients see improvements as a result of physical therapy management; therefore, a better understanding of biomechanics and assessment of clinical outcomes between responders and non-responders is required. The included participants will be provided with informed consent and an explanation of the study procedure before enrolling in data collection. The data collection will be arranged in the same order. Practice trials will be provided before the start of data collection. The data collection will consist of standardized questionnaires, assessments, and tests commonly used in clinics.
To assess postoperative patient-reported quality of recovery after total knee arthroplasty (TKA) with periarticular joint injection (PAI) ± single shot adductor canal block with or without adductor canal catheter infusion.
The overall aim of this trial is to compare functional and patient-reported outcomes and to assess the safety and effectiveness and long-term performance of the Smith+Nephew Robotic Systems for Unicompartmental Knee Replacements to non-robotic, conventionally implanted Unicompartmental Knee Replacements.
The goal of this observational study is to investigate the potential of wearable sensors for monitoring the postoperative recovery of patients after TKA. The main question the study aims to answer is: • whether alterations in gait characteristics and the changes in PA levels measured by wearable PA trackers can accurately reflect a patient's postoperative recovery status and provide clinically relevant information to aid their management. Participants will wear PA trackers during the perioperative period of TKA (2 weeks before until 3 months after, and then agin for 2 weeks one year after the surgery) and we will analyze their gait and PA and correlate them with their recovery after surgery.
The investigators aimed to compare two doses of intravenous (IV) tranexamic acid (TXA) with a combined single dose of topical and IV TXA on haemoglobin decline 24 hours after total joint arthroplasties. The investigators conducted randomized, double-blind trial. The participants were randomized to either intrvenous group receiving 2 doses of 1 gram TXA in intravenous route 3 hours apart, or a combined application group receiving the first 1 gram IV and the topical dose was 1.5 gram after reduction of the fascia.
Multimodal analgesia (MMA) has been endorsed to improve postoperative analgesia and functional activity after surgery, and integrating regional analgesia to reduce the consumption of opioid has also been used in postoperative pain management. The investigator try to find a better combination of MMA for postoperative analgesia and functional recovery for patients receiving TKA in Taiwan, therefore the effect of single-injection and continuous infusion of peripheral nerve block is compared in patient undergoing unilateral TKA. The investigators hypothesize that continuous adductor canal infusion is as effective as single-injection adductor canal block for postoperative pain relief under intravenous PCA after TKA surgery. Based on that, the investigators conduct this prospective, randomized controlled trial to examine our hypothesis.
