BACKGROUND The use of surgical simulation in orthopaedic education is increasing; however, its ideal place within the training curriculum remains unknown. The purpose of this study was to determine the effectiveness of training novice surgeons on an anatomic dry model of the knee prior to training them to perform diagnostic arthroscopy on cadaveric(More)
SUMMARY Quantification applications of short-tag sequencing data (such as CNVseq and RNAseq) depend on knowing the uniqueness of specific genomic regions at a given threshold of error. Here, we present the 'uniqueome', a genomic resource for understanding the uniquely mappable proportion of genomic sequences. Pre-computed data are available for human,(More)
BACKGROUND Surgeries employing arthroscopic techniques are among the most commonly performed in orthopaedic clinical practice; however, valid and reliable methods of assessing the arthroscopic skill of orthopaedic surgeons are lacking. HYPOTHESIS The Arthroscopic Surgery Skill Evaluation Tool (ASSET) will demonstrate content validity, concurrent(More)
BACKGROUND Examination of arthroscopic skill requires evaluation tools that are valid and reliable with clear criteria for passing. The Arthroscopic Surgery Skill Evaluation Tool was developed as a video-based assessment of technical skill with criteria for passing established by a panel of experts. The purpose of this study was to test the validity and(More)
PURPOSE To determine the validity and reliability of using the Arthroscopic Surgery Skill Evaluation Tool (ASSET) to assess arthroscopic skill in the operating room. METHODS Eight orthopaedic residents, 1 sports medicine fellow, and 3 sports medicine faculty members recorded the diagnostic portion of 3 shoulder and 3 knee procedures in the operating room.(More)
BACKGROUND The Basic Arthroscopic Knee Skill Scoring System (BAKSSS) has construct validity as an objective measure of arthroscopic proficiency when used to assess the task of performing arthroscopic meniscectomies on cadaver knees. The reliability of this instrument is unknown. QUESTIONS/PURPOSE We asked whether (1) a simple modification of the BAKSSS(More)
We report on a female patient with a severe allergic contact dermatitis of the lower legs due to Varicosan, a special bandage material for varicosis. We found a sensitization against methyl- and propylesters of parahydroxybenzoic acid. This preservatives could be identified in Varicosan bandages.
