Noise exposure due to orthopaedic saws in simulated TKR surgery
In some orthopaedic procedures, including total knee arthroplasty (TKA), surgeons are exposed to noise generated by powered instruments, with a risk of developing occupational hearing loss. A new saw design, the Stryker PrecisionTM system, has been developed which may reduce noise during TKA surgery. The new system was tested against a standard Stryker System-5 sagittal saw in simulated TKA surgery using porcine cadaveric femurs, and noise levels from the cuts were measured. The average noise level of the PrecisionTM system, LAeq=81.6dBA, was significantly lower than that of the System-5 saw, LAeq=88.9dBA (p=0.003). Calculated 8-hour values for both blade systems were within Health & Safety guidelines. It was concluded that the PrecisionTM system produced a lower risk of noise-induced hearing loss than the System-5 saw

Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
