Filter by:The purpose of this study was to investigate whether polyethylene (Vitamin E-containing polyethylene), which has been newly introduced and widely used clinically as a biomaterial for tibial inserts in total knee arthroplasty, but whose mid- to long-term clinical results are still unknown, is more effective than conventional polyethylene. Our goal is to clarify through an international multi-center joint study using in vivo polyethylene wear particle analysis, which the investigators developed as a method to provide early feedback, as to whether polyethylene wear debris production in vivo can be reduced.
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 goal of this observational study is to determine the incidence of dislodgement for adductor canal catheters after total knee arthroplasty on post-operative day 1. We will also attempt to identify factors associated with secondary catheter failure.
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.
To evaluate the effects of early oral carbohydrates after TKA on nutritional status, comfort and safety in elderly patients.
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.
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
The aim of this study is to assess the long-term performance and safety of HLS KneeTec Deep Dish knee prosthesis when used in standard medical practice
The purpose of this study is to determine the most efficacious and safest dexamethasone dose given intraoperatively during total knee arthroplasty that reduces postoperative opioid consumption and pain, improves postoperative nausea and vomiting, and minimizes postoperative complications.
The aim of this study is to assess the long-term performance and safety of HLS KneeTec cementless and hybrid fixation knee prosthesis when used in standard medical practice.
