TABLE 1.

Goodness of fit of the viscous (Crisco et al., 2007) and boundary (Stanton, 1923) friction model to the recorded flexion-extension data under swing and stance phase loading conditions and the meniscus states intact, after simulation of a posterior medial meniscus root tear (PMMR tear) and after medial meniscectomy (MM), represented by R-squared values (n = 6, mean ± standard deviation).

	Intact		PMMR tear		MM
