UNLABELLED Osteoarthrosis is the most frequent joint disorder in the world. An increased incidence of total hip replacement (THR) and total knee replacement (TKR) has been noticed recently. AIM To investigate demographic characteristics, comorbidities, surgical factors and postoperative complications of patients who received THR or TKR. MATERIAL AND METHOD Patients aged at least 30 years ho...

Patella infera may occur after reconstruction of the anterior cruciate ligament (ACL), high tibial osteotomy and total knee replacement (TKR). Restriction of movement of the knee and pain may result. Our aim was to compare the incidence and to assess the effects of patella infera after TKR and unicompartmental knee replacement (UKR). We reviewed radiographs of the knees of 84 patients who had h...

Design patterns are useful in Software Engineering to abstract common implementations regardless of the scope of application. This paper presents a metamodel for Trading-based Knowledge Representation (TKR), which embeds useful design patters for modeling Management Information Systems (MIS). The paper presents a case study in which this TKR metamodel is used to specify an Environmental Managem...

We randomised 102 knees suitable for a unicompartmental replacement to receive either a unicompartmental (UKR) or total knee replacement (TKR) after arthrotomy. Both groups were well matched with a predominance of females and a mean age of 69 years. Patients in the UKR group showed less perioperative morbidity, but regained knee movement more rapidly and were discharged from hospital sooner. At...

OBJECTIVE To predict, using clinical and qMRI data, the incidence of total knee replacement (TKR) during the long-term follow-up of knee osteoarthritis (OA) patients who formerly received chondroitin sulfate (CS) or placebo treatment. DESIGN A post hoc intention-to-treat analysis to evaluate the incidence of TKR was done on knee OA patients who had participated in a 12-month trial evaluating ...

OBJECTIVE There is growing understanding of the importance of bone in OA. Our aim was to determine the relationship between 3D MRI bone shape and total knee replacement (TKR). METHODS A nested case-control study within the Osteoarthritis Initiative cohort identified case knees with confirmed TKR for OA and controls that were matched using propensity scores. Active appearance modelling quantif...

High-flexion total knee replacement (TKR) designs have been introduced to improve flexion after TKR. Although the early results of such designs were promising, recent literature has raised concerns about the incidence of early loosening of the femoral component. We compared the minimum force required to cause femoral component loosening for six high-flexion and six conventional TKR designs in a...

The aim of this project is to investigate what kind of terminological knowledge representation system (TKR-system) is able to support the modeling of huge chemical plants. In this highly complex modeling application, a TKR-system is the appropriate tool to serve as a user{database interface. What distinguishes TKR-systems from database systems is their ability to infer implicit knowledge from t...

BACKGROUND This study evaluated the effect of early anti-tumor necrosis factor (TNF) therapy in patients with severe rheumatoid arthritis (RA) on the subsequent risk of total knee replacement (TKR) surgery. METHODS This retrospective observational study included a hospital-based cohort of 200 patients diagnosed with severe RA who received treatment with anti-TNF therapy between 2003 and 2014....

BACKGROUND Multimodal analgesia featuring peripheral nerve blocks decreases postoperative pain for patients undergoing primary total knee arthroplasty (TKA). Many anesthesiologists and surgeons advocate for the use of adductor canal blocks (ACBs) for analgesia, which result in less weakness compared to femoral nerve blocks. Few data exist to guide analgesic management in total knee revision (TK...
