Knee joint biomechanics in high flexion.
Hirokawa S, et al. ScientificWorldJournal 2014. PMID 25136670 Free PMC article.
Biomechanics of the Anterolateral Structures of the Knee.
Kittl C, et al. Clin Sports Med 2018 - Review. PMID 29173554 Free article.
This article describes the complex anatomic structures that pass across the lateral aspect of the knee, particularly the iliotibial tract and the underlying anterolateral ligament and capsule. It provides data on their strength and roles in controlling tibiofemoral joint laxity and stability. These findings are discussed in relation to surgery to repair or reconstruct the anatomic structures, or to create tenodeses with similar effect....

Design, construction, and evaluation of "sensor lock": an electromechanical stance control knee joint.
Arazpour M, et al. Disabil Rehabil Assist Technol 2018. PMID 28350511
BACKGROUND AND AIM: Most currently-available stance control knee ankle foot orthoses (SCKAFOs) still need full knee extension to lock the knee joint, and they are still noisy, bulky, and heavy. ...The feasibility of the new knee joint with able-bodied people and poliomyelitis subjects was demonstrated....

Comparison between kinetic and kinetic-kinematic driven knee joint finite element models.
Bolcos PO, et al. Sci Rep 2018. PMID 30478347 Free PMC article.
Use of knee joint finite element models for diagnostic purposes is challenging due to their complexity. Therefore, simpler models are needed for studies where a high number of patients need to be analyzed, without compromising the results of the model. ...We suggest that it is feasible to use kinetic-kinematic driven knee joint models with a simpler geometry in studies with a large cohort size, particularly when analyzing cartilage responses and failures related to potential overloads....

Elevated Knee Joint Kinetics and Reduced Ankle Kinetics Are Present During Jogging and Hopping After Achilles Tendon Ruptures.
Willy RW, et al. Am J Sports Med 2017. PMID 28186834
These deficits may result in an altered distribution of joint loads during lower extremity tasks. HYPOTHESIS: We hypothesized that, regardless of treatment, the Achilles tendon-ruptured limb would exhibit deficits in ankle kinematics and joint power while exhibiting elevated knee joint power and patellofemoral joint loads during walking, jogging, and hopping. ...Interestingly, only jogging and hopping demonstrated greater knee joint loads when compared with the uninvolved limb. Concentric knee power was greater during jogging (LSI: 117.2%) and hopping (LSI: 115.9%) compared with the uninvolved limb. ...

Design of a knee joint mechanism that adapts to individual physiology.
Jiun-Yih Kuan , et al. Conf Proc IEEE Eng Med Biol Soc 2014. PMID 25570389
This paper describes the design of a new knee joint mechanism, called the Adaptive Coupling Joint (ACJ). The new mechanism has an adaptive trajectory of the center of rotations (COR) that automatically matches those of the attached biological joint. ...It is shown that the ACJ can transmit planetary torques from either active or passive devices to the limbs without altering the normal biological joint motion....

Knee joint forces during isokinetic knee extensions: a case study.
Chow JW. Clin Biomech (Bristol, Avon) 1999. PMID 10521610
The gravitational and inertial effects were included in determining the resultant knee torque. Knee radiographs were used to determine the knee joint geometry. A combination of knee torque and geometric data was used to determine different knee joint forces. RESULTS: All knee joint forces were found to decrease with increasing isokinetic speed. ...

Multi-plane, multi-joint lower extremity support moments during a rapid deceleration task: Implications for knee loading.
Podraza JT, et al. Hum Mov Sci 2018. PMID 29448160
Repeated measures ANOVA compared LSMs and the contribution of individual joint moments at initial contact (IC) and 50 ms after. ...Analyses of individual joint moments emphasized the critical role that the hip joint moments have in balancing potentially injurious knee moments in all three planes for all three landing conditions....

Knee joint passive stiffness and moment in sagittal and frontal planes markedly increase with compression.
Marouane H, et al. Comput Methods Biomech Biomed Engin 2015. PMID 23682906
To quantify the effect of compression on passive knee moment resistance and stiffness, two validated finite element models of the tibiofemoral (TF) joint, one refined with depth-dependent fibril-reinforced cartilage and the other less refined with homogeneous isotropic cartilage, are used. ...While the angular rigidity would enhance the joint stability, the augmented passive moment resistance under compression preloads plays a role in supporting external moments and should as such be considered in the knee joint musculoskeletal models....

Contribution of tibiofemoral joint contact to net loads at the knee in gait.
Walter JP, et al. J Orthop Res 2015. PMID 25676012 Free article.
Inverse dynamics analysis is commonly used to estimate the net loads at a joint during human motion. Most lower-limb models of movement represent the knee as a simple hinge joint when calculating muscle forces. ...The results of this study may be used to guide the development of more realistic lower-limb models that account for the effects of tibiofemoral joint contact at the knee....
