Noise exposure due to orthopedic saws in simulated total knee arthroplasty surgery

J Arthroplasty. 2007 Dec;22(8):1193-7. doi: 10.1016/j.arth.2007.05.048.

Abstract

In some orthopedic 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 Precision system (Stryker, Kalamazoo, Mich), has been developed that 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 Precision system, L(Aeq) = 81.6 dB(A), was significantly lower than that of the System 5 saw, L(Aeq) = 88.9 dB(A) (P = .003). Calculated 8-hour values for both blade systems were within Health and Safety guidelines. It was concluded that the Precision system produced a lower risk of noise-induced hearing loss than the System 5 saw.
