Patients’ assessment was performed preoperatively, as well as at 1, 2 and 6 months postoperatively, by the isokinetic method. Healthy adults were assessed once by the same method. Isokinetic evaluation of knee extensor and flexor muscles was performed using a Gimnex Iso 2 dynamometer. After a warm-up protocol, measurements were done at angular velocities of 90 and 180°/sec. <em>Results</em>: Compared to healthy adults, patients performed significantly worse at all evaluation times, for both extensors and flexors of the knee, except for the 6-month evaluation at 180°/sec. One month postoperatively losses from preoperative levels were registered in patients, but without statistically significance, except for extension at 180°/sec. At 6 months postoperatively patients surpassed the preoperative levels, with statistical significance at 180°/sec. <em>Conclusions</em>: Power is an important parameter to follow after TKA, in parallel with peak torque. Increasing muscle power should be one of the central issues to address during postoperative rehabilitation.<br />}, number={3}, journal={Applied Medical Informatics}, author={BORDA, Ileana Monica and IRSAY, Laszlo and UNGUR, Rodica and CIORTEA, Viorela and ONAC, Ioan and SUSMAN, Alina and POP, Liviu}, year={2012}, month={Sep.}, pages={9–16} }
