BACKGROUND Patient-specific femoral and tibial cutting blocks produced with use of data from preoperative computed tomography (CT) or magnetic resonance imaging (MRI) scans have been employed recently to optimize component alignment in total knee arthroplasty. We report the results of a randomized controlled trial in which CT scans were used to compare postoperative component alignment between ...

OBJECTIVES To identify patient-assessed health instruments specific to the knee and review evidence for reliability, validity and responsiveness. METHODS Instruments were identified through systematic searches of the literature. Information relating to instrument content, patient population, reliability, validity and responsiveness was extracted from published papers. RESULTS The 16 instrum...

BACKGROUND To improve the detection, diagnosis and follow-up of depression in primary care patients, it has been proposed that GPs should employ assessment instruments as a complement to the consultation. However, most GPs do not use such instruments routinely. OBJECTIVE To explore perceptions of Swedish GPs on the use of instruments in the medical consultation. METHODS Twenty-seven GPs dis...

Background: The aim of this study is to evaluate the accuracy of bone cuts and the resultant alignment, using theMyKnee patient specific cutting blocks.Methods: We retrospectively reviewed 132 patients undergoing primary TKR for osteoarthritis by one single surgeon.The operative time, the preoperative Hip-Knee-Ankle (HKA) axis based on the CT-scan, the postoperative HKA axisbased on long axis s...

This paper describes the reuse capability that Boeing has developed as one of the prime contractors on the U.S. Advanced Research Projects Agency (ARPA) Software Technology for Adaptable, Reliable Systems (STARS) program. The capability uses object–oriented and knowledge–based technology to support asset management and utilization and is being used on a joint U.S. Navy/Boeing demonstration proj...
