BACKGROUND The use of an interference fit wedged bone plug to provide fixation in the tibial tunnel when using bone-patellar tendon-bone autograft for anterior cruciate ligament reconstruction offers many theoretic advantages including the potential to offer a more economical and biological alternative to screw fixation. This technique has not been subjected to biomechanical testing. We hypothe...

Cementless femoral total knee arthroplasty (TKA) components use a press-fit (referred to as interference fit) achieve initial fixation. A higher fit could lead superior fixation, but it also introduce more damage the bone during implantation. The purpose of current study was investigate effect on micromotions and gap opening/closing at bone-implant interface. Experimental tests were performed i...

BACKGROUND To examine the prevalence of significant interference from heterophile antibodies (HAb) in the measurement of serum thyroglobulin (Tg), we evaluated a large cohort of samples from patients with differentiated thyroid carcinoma (DTC). METHODS Serum Tg measurements were performed in 406 serum samples before and after incubation of each serum sample in heterophile-blocking tubes (HBT)...

A transmitter identification system using embedded spread spectrum sequence is proposed. Code generators are developed to study the auto-correlation and cross-correlation properties of the truncated Gold and Kasami sequences. To reduce the computation complexity, the embedded Kasami sequence is time-synchronized with the DTV frame structure. Therefore, the Kasami sequence length has to be trunc...

OBJECTIVES Endogenous antibodies (EA) may interfere with immunoassays, causing erroneous results for hormone analyses. As (in most cases) this interference arises from the assay format and most immunoassays, even from different manufacturers, are constructed in a similar way, it is possible for a single type of EA to interfere with different immunoassays. Here we describe the case of a patient ...

Although there is a long tradition of empirical studies of software developers, few studies have focused on software maintenance. Prior work is predicated on the belief that higher levels of software comprehension are associated with higher levels of performance on modification tasks. This study provides a more complete understanding of the relationship between software comprehension and modifi...

Decisions are often based on the results of quantitative analysis. To gain confidence in these results, some indication of their quality is needed. Measurement uncertainty, as proposed by the International Organization for Standardization (ISO), is a way to express this quality. Most measurement techniques compare references and therefore need to be calibrated. Usually least squares methods ign...

BACKGROUND Tibial aperture fixation with a bioabsorbable interference screw is a popular fixation method in anterior cruciate ligament reconstruction (ACLR). An interference screw containing β-tricalcium phosphate (β-TCP) to improve bony integration and biocompatibility was recently introduced. This study aims to compare the clinical outcomes and radiological results of tunnel enlargement effec...
