Abstract

The vibrations produced during the cutting of the tibia during a total knee arthroplasty (TKA) tibial osteotomy are monitored. The natural frequencies of tibia occur at 600, 1300, and 2500 Hz. The major peaks in the power density spectrum occur at regular intervals of 85-100 Hz, and the largest peak occurs at 600 Hz. When the peaks reach a natural frequency, the acceleration and the resulting displacement of the tibia is high. The oscillating flow excites the natural frequencies of the tibia during osteotomy. A dynamic absorber is used to eliminate vibrations. Smoother tibial surface is observed when vibration is reduced, resulting in better bone ingrowth into the porous coated implants.
