Abstract
. Cement removal at revision hip arthroplasty forms a critical step for a successful operation. The removal of polymethymethacrylate (PMMA) with curet and chisel can cause major damage to the femoral shaft. The use of ultrasound or lithotripsy can cause perforation and microfractures to bone tissue. The goal of our study was to evaluate the application and practicability of different laser systems for cement removal. We examined and compared the effects of a diode laser (wavelength λ=800 nm), a Nd:YAG laser (λ=1064 nm), and an Er:YSSG laser (λ=2780 nm) on PMMA and the PMMA–bone interface.
