Filter by:Immediate rehabilitation after total knee arthroplasty (TKA) differs in terms of volume, intensity but also type of treatment. Continuous passive motion after TKA is so far only investigated for replacing physiotherapy. This study is conducted to investigate CPM when it partially replaces group physiotherapy in terms of functional and patient-reported outcomes.
The aim of the study is to measure the validity and reliability of the StUD test in patients with TKA. Forty-seven patients with primary TKA included in this study. The test-retest reliability of the StUD test was measured with 1-hour interval. Validity was assessed that the 30s Chair Stand Test (30sCS), the Hospital for Special Surgery score (HSS) and Short Form-12 Quality Life Questionnaire (SF-12) were used as comparator instruments.
ABSTRACT INTRODUCTION Knee osteoarthritis is a common joint pathology causing joint pain and ambulatory limitations. In primary total knee arthroplasty (TKA) surgeries, medial parapatellar (MP) and subvastus (SV) approaches are frequently used. The MP approach provides good exposure and is more widely used. In the SV approach, the vastus medialis muscle is preserved. Some argue that the extensor mechanism may heal earlier with the SV approach. In this study, unlike previous studies, the investigators aimed to quantitatively compare the early outcomes of MP and SV approaches, through shear wave elastography (SWE) measurements isolated over the vastus medialis and vastus lateralis muscles. MATERIALS AND METHODS The study included 20 patients with indications for TKA due to primary osteoarthritis, divided into MP and SV groups. SWE measurements of the vastus medialis and vastus lateralis muscles were performed preoperatively and at 3-month follow-up. Clinical scores (Knee Society Score and WOMAC) and straight leg raising time were recorded both preoperatively and postoperatively.
The goal of this interventional study is to examine whether a pain management technique of combined femoral and popliteal nerve block is effective in total knee arthroplasty patients. The main questions it aims to answer are: Are there differences in postoperative outcomes? Does the nerve block, age, preoperative quadriceps muscle strength and Oxford Knee Score of the patient predict early functional ability? Participants underwent total knee arthroplasty and assessments. Researchers compared pain management techniques to assess effects on postoperative outcomes and identified the importance of preoperative variables a predictors of early functional ability. Further research is required to refine postoperative pain management strategies.
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.
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.
This project aims to investigate the feasibility of a low load (LL) isokinetic knee flexor and extensor strength training (ST) protocol under blood flow restriction (BFR) conditions in early postoperative total knee arthroplasty patients. The intervention consists in testing an experimental strengthening protocol in the Leukerbad Clinic. 12 participants will be recruited and the intervention will last approximatively 3 weeks and will consist in 3 weekly ST. The collected data will then be analysed and interpreted to define if such an intervention is feasible or not.
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.
Early postoperative rehabilitation programs after TKA aims to provide optimal functional recovery. The current rehabilitation process in TKA typically includes 2 to 3 months post-surgery, as the greatest declines in strength and functional performance occur immediately after surgery. Yet, the content, duration, and intensity of the rehabilitation programs for the reorganization of physical function after surgery have not yet been fully clarified. Whether home-based rehabilitation is comparable to supervised rehabilitation in the midterm period requires further research, as practices after TKA vary. The purpose of this study is to compare the effectiveness of supervised and home-based progressive resistance training (PRT) in the midterm postoperative period in female patients undergoing TKA.
The present study analyzes the effects of using a portable single limb exoskeleton (MAKv1) in patients with total knee artrhoplasty (TKA). Safety, usability and clinical effects of an early intervention program with the device with an early implementation are studied.
