Filter by:Total knee replacement is used in the treatment of patients with knee arthritis, rheumatoid arthritis and other knee disorders. Today, there are basically two designs; It cuts the posterior cruciate ligament (PS) and protects the posterior cruciate ligament (CR). Although there is no clear study suggesting which design is better, research on this subject has increased recently. the investigators aim is to define the superiority of these two designs over each other. Preoperative and postoperative joint range of motion examinations were performed on both knees separately. WOMAC and OXFORD scores were examined separately for both knees.
The life expectancy worldwide is increasing and leading to an increase of knee arthroplasty. Also, as millions of people around the world are currently living with a Total Knee Arthroplasty (TKA), the need for revision surgery represents a large public health burden. In this context, FH ORTHO company develops FHK®-CK (prosthesis + ancillary equipment) which is a knee prosthesis for complex first intention and revision knee arthroplasty. This new medical device complements the FHK® standard first-line range (CE marked). The FHK®-CK ancillary equipment were designed by expert knee surgeons and is simple, reliable and reproducible. It allows for maximum versatility while remaining compact. By completing the FHK® range of first intention prostheses, the FHK®-CK allows the surgeon to be on the same level as the competitors by having a first intention and semi-constrained prosthesis. This prosthetic arsenal allows the surgeon to opt for the best solution for his patient so that he can regain mobility and a satisfactory quality of life. Also, in case of failure of the FHK® first-line prosthesis, it will provide the surgeon and the patient with a simple alternative to prosthesis replacement. As it has been developed in line with the first intention, inter-compatibility between the two systems is possible, which simplifies the surgical procedure and reduces the risks for the patient.
In recent years, pain management coordinated with enhanced recovery after surgery (ERAS) has been widely applied and rapidly developed in orthopedics, showing promising prospects. Since 2016, our hospital has used a series of continuously improved pain management schemes for patients with knee OA who underwent total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA), and high tibial osteotomy (HTO). Here, we retrospectively analyze these patients' clinical data to compare the effects of different pain intervention measures during the perioperative period on postoperative pain, functional exercise, hospital stay, and prognosis of the three surgical methods in an attempt to provide a feasible solution for pain management of these patients.
In patients who have had joint replacement surgery, there is a shortage of concrete evidence regarding the effectiveness of telerehabilitation. The aim of this study is to compare telerehabilitation with home based exercise program and standard home exercise program in total knee arthroplasty.
A prospective multicenter longitudinal cohort study of Zimmer Biomet (ZB) Persona IQ The Smart Knee which consists of the Persona Personalized Knee (PPK) System with mymobility® platform that is attempting to develop correlative measures to assist surgeons in understanding and managing risk in their patient populations. Specifically comparing four outcome measures captured via Remote Therapeutic Monitoring (RTM) utilizing the CANARY canturioTM Tibial Extension (CTE) sensors in combination with the mymobility® App. The primary objective of this prospective study is to systematically document the clinical outcomes of the Persona IQ Personalized Knee System with mymobility for primary total knee arthroplasty/replacement (TKA/TKR). This will be accomplished by monitoring subject activity trend patterns via the mymobility platform, evaluating smart system usability, monitoring short and long-term safety and effectiveness, and evaluating the value of the remote therapeutic monitoring platform. This data collection will be accomplished by the following: 1. The Canary Smart Tibial Stem comprised of the following subsystems: 1. Canary Cloud Data Management Platform (CDMP) 2. Canary Medical Gait Parameters (CMGP) Software Module 2. Persona IQ Personalized Knee System with mymobility Platform comprised of the following subsystems: 1. mymobility Platform for Patient Application 2. mymobility Care Team Dashboard 3. ZB Edge Artificial Intelligence Data Platform 3. Clinical Outcomes 1. Joint Motion: ROM and Deductions 2. Joint Stability: Medial/Lateral and Anterior/Posterior 3. Gait and Assistive Device Utilization 4. Surgical Incision Site 4. Objective Measurements: a. Timed Up & Go (TUG) and Stair Climb Test 5. System Usability Evaluation 6. Patient Satisfaction 7. Health Care Provider Satisfaction Additionally, a data repository will be maintained for future secondary data analyses when data is transmitted and captured beyond the 1-year of follow-up.
This is a prospective randomized controlled trial that will assess preoperative, perioperative, and long-term oxidative stress (OS); pain; and functional outcomes over a 12 month period and test the hypothesis that a potent antioxidant intervention (glycine + N-acetyl-cysteine(GlyNAC)) reduces oxidative stress and chronic post surgical pain (CPSP) in patients undergoing total knee arthroplasty (TKA).
Maneuverability is currently under appreciated by patients who are seeking mobility. This pilot study is examining how patients maneuverability and mobility will change with this novel mobility tool - A-Linker compared to the standard of care walker.
Total Knee Arthroplasty (TKA) is actually the most effective treatment option for patients with end-stage osteoarthritis (OA). However, nearly 20% of patients who underwent TKA remain unsatisfied with their clinical outcome. Investigating modifiable factors that limit knee functioning following TKA we may notice the significance of lower limb muscles strength. Gait pattern is also affected by OA, as arthritic knee joint cannot provide proper range of motion (ROM) and stability.Therefore any deviation in biomechanics should be noticed and analyzed. After TKA patients' physical function may change, but the study should be conducted to prove whether it improves or not. Patient-reported outcome defined by OKS (Oxford Knee Score) and FJS (Forgotten Joint Score) questionnaires will be evaluated.
The goal of this prospective observational study is to explore the feasibility of preoperative peripheral venous cannulation pain score in predicting acute pain after total knee arthroplasty, including resting pain and movement-evoked pain.
Purpose: A robotic system was recently introduced to improve prosthetic alignment during total knee arthroplasty (TKA). The purpose of this multicenter prospective randomized controlled trial (RCT) study was to determine whether robotic-arm-assisted TKA improves the clinical and radiological outcomes in patients compared to conventional TKA. Methods: One hundred and thirty patients who underwent primary TKA were enrolled in this prospective, multicenter RCT conducted in 3 hospitals. Five patients were lost to follow-up at 6 weeks after surgery. Therefore, 125 patients (63 in the intervention group and 62 in the control group) remained in the final analysis. The primary outcome was the rate of patients whose mechanical axis of the femur was less than 3° deviated from the mechanical axis of the tibia evaluated by full-length weight-bearing X-rays of the lower limb at 6 weeks postoperatively. Secondary outcomes will include operation times, 6-week postoperative functional outcomes evaluated by the American Knee Society Score (KSS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), SF-36, adverse events (AEs) and serious adverse events (SAEs). Hypothesis: Robotic-arm-assisted TKA is safe and effective as demonstrated in this trial.
