Filter by: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.
The cementless ATTUNETM Rotating Platform Knee system was compared in a single-blind, randomized RSA trial to its predecessor, the LCS rotating platform Knee System. In this previous study, 61 knees were subjected to RSA examinations at 1-day and 3, 6, 12 and 24 months postoperative. This study found a promising equal migration of both tibial components and a lesser migration of the femoral component of the ATTUNETM knee system after two years, although with a similar migration rate between year 1 and 2. this raises the question of whether the migration of the prostheses relative to each other will increase or remain the same in the long term. To examine this, a mid-and long-term RSA follow-up to measure migration is necessary. In addition, another new RSA measurement parameter has become known in recent years that may provide an indication of the bonding of the prosthesis to the bone at the time of measurement. This new parameter, called the Induced Displacement (ID) of a prosthesis, measures the position and orientation relative to the bone while the prosthesis is under different loading conditions (e.g., patient in supine or standing position). This means that a large measured difference between these different loading condition measurements would indicate that osseointegration of the prosthesis never occurred or is no longer present. To improve the understanding of the tendency of both prostheses to aseptic loosening after a mid- to long-term follow up, migration over time and inducible displacement analyses are necessary. The primary objective of this study is to accurately compare mid- and long-term migration of two uncemented TKR prostheses. The secondary objectives of this study are to evaluate if inducible displacement can be used as a parameter to detect loose implants, and to compare inducible displacement, clinical and radiological outcome and patient-reported outcomes (PROMS) after a follow-up of 5 and 10 years of two uncemented TKR prostheses.
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.
To evaluate the effects of early oral carbohydrates after TKA on nutritional status, comfort and safety in elderly patients.
Many surgeons choose to perform total knee arthroplasty (TKA) surgery with the aid of a tourniquet. A tourniquet is a device that fits around the leg and restricts blood flow to the limb. There is a need to understand whether tourniquets are safe, and if they benefit, or harm, patients. The aim of this study was to determine the benefits and harms of tourniquet use in TKA surgery
Phase Ⅱ, randomized, double-blind, comparator-controlled study to evaluate the efficacy, safety and pharmacokinetics of single injection adductor canal block with HR18034 for postoperative pain management compared with ropivacaine.
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.
This is a single-site, prospective, clinical study of subjects that are scheduled to undergo either total hip or total knee arthroplasties. It is anticipated that surgical wounds treated with SurgX will exhibit reduced surgical site complication rates and improved post-operative treatment outcomes by potentially decreasing site bioburden of both free-floating and biofilm-entrenched organisms.
An alternative to improve the quality of postoperative analgesia is to use various perineural adjuvants applicable to peripheral nerve block along with local anesthetics to increase the analgesic effect. Dexamethasone is a strong and long-acting corticosteroid, which reduces postoperative nausea and vomiting and increases the duration of nerve blockade. Most of the existing clinical studies compared the analgesic effect with the placebo group after adding an adjuvant in a single shot nerve block, and there were very few cases of comparing the analgesic effect with the placebo group after adding the adjuvant in peripheral nerve block through continuous catheter infusion. Therefore, we designed this study to investigate whether the use of dexamethasone as a peripheral adjuvant for continuous femoral nerve block has a better pain and recovery profile.
Total knee arthroplasty (TKA) with the sacrifice of the anterior cruciate ligament is the standard treatment for severe knee osteoarthritis. A number of studies on the kinematics of the prosthetic knee tend to show that implants that preserve the cruciate ligaments best reproduce the kinematics of the healthy knee. The goal is to compare the clinical and radiological results in patients undergoing total knee replacement surgery according to the type of prosthesis used. It is anticipated that the bicruciate-retaining prosthesis will result in better function of the operated knee than the posterior-stabilized prosthesis. Method: - Randomized controlled trial - Monocentric - Randomization will be done using sealed envelopes
