Knee hyperflexion
WebKnee flexion is when the lower leg and foot bends and is raised posteriorly at the knee joint, while the thigh remains fixed in a stationary position. The estimated peak of the range of motion varies from 115-160° (Roaas & Andersson 1982, Gilroy et al. 2006, Pinskerova et al. 2009, Washington State DSHS 2014, Quinn 2024). WebJun 2, 2014 · Biomechanics of hyperflexion and kneeling before and after total knee arthroplasty. The capacity to perform certain activities is frequently compromised after total knee arthroplasty (TKA) due to a functional decline resulting from decreased range of motion and a diminished ability to kneel.
