Background: Various sizes of implants need to be available during surgery. The purpose of this paper is to comparebody height and shoe size with implant sizes in patients who underwent total knee replacement surgery to see whichbiomarker is a better predictor for preoperative planning to determine implant size.Methods: A total of 100 knees, belonging to 50 females and 50 males, were observed. P...

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...

Haemophilia is an x-linked inherited bleeding disorder which can cause severe arthropathy. We have reviewed the results of 70 primary total knee replacements (TKR) performed in 57 haemophilic patients between 1983 and 2007. The functional results were assessed using the Hospital for Special Surgery (HSS) knee scoring system and Kaplan-Meier survivorship analysis. Six patients died. HSS scores w...

The purpose of this meta-analysis and systematic review was to identify and assess whether circumferential electrocautery is useful for improving outcomes after primary total knee replacement(TKR). We searched MEDLINE, EMBASE, PubMed, SpringerLink, Web of Knowledge, OVID CINAHL, OVID EBM and Google Scholar and included articles published through January 2014. A total of 6 articles met the inclu...

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...
