Complex function of the knee joint: the current understanding of the knee.
Hirschmann MT and Müller W. Knee Surg Sports Traumatol Arthrosc 2015 - Review. PMID 25962963
During the evolution of mankind, the knee has been optimally adapted to the forces and loads acting at and through the knee joint. ...It is the purpose of this review to perform a systematic review of knee anatomy, highlight the complex function of the knee joint and present an overview about recent and current knowledge about knee function. ...

Knee joint biomechanics in high flexion.
Hirokawa S, et al. ScientificWorldJournal 2014. PMID 25136670 Free PMC article.
A joint coordinate system for the clinical description of three-dimensional motions: application to the knee.
Grood ES and Suntay WJ. J Biomech Eng 1983. PMID 6865355
The experimental study of joint kinematics in three dimensions requires the description and measurement of six motion components. ...The coordinate system is applied to the knee and related to the commonly used clinical terms for knee joint motion. A convenient characteristic of the coordinate system shared by spatial linkages is that large joint displacements are independent of the order in which the component translations and rotations occur....

Knee biomechanics of the dynamic squat exercise.
Escamilla RF. Med Sci Sports Exerc 2001 - Review. PMID 11194098
Hence, training the squat in the functional range between 0 and 50 degrees knee flexion may be appropriate for many knee rehabilitation patients, because knee forces were minimum in the functional range. Quadriceps, hamstrings, and gastrocnemius activity generally increased as knee flexion increased, which supports athletes with healthy knees performing the parallel squat (thighs parallel to ground at maximum knee flexion) between 0 and 100 degrees knee flexion. ...

The association of ankle dorsiflexion and dynamic knee valgus: A systematic review and meta-analysis.
Lima YL, et al. Phys Ther Sport 2018 - Review. PMID 28974358
OBJECTIVE: The objective of this systematic review was to evaluate the association between ankle dorsiflexion (ADF) and dynamic knee valgus (DKV). ...Subgroup analysis showed consistent results regarding different forms of ADF measurement; restriction in ADF measured in weight-bearing position (SMD -1.25, 95% CI -2.24 to -0.25), non-weight-bearing with knee flexed (SMD -0.56, 95% CI -0.97 to -0.16) or non-weight-bearing with knee extended (SMD -0.54, 95% CI -0.80 to -0.28) was significantly associated with DKV. ...

The effect of constitutive representations and structural constituents of ligaments on knee joint mechanics.
Orozco GA, et al. Sci Rep 2018. PMID 29396466 Free PMC article.
Ligaments provide stability to the human knee joint and play an essential role in restraining motion during daily activities. ...Knee joint forces for the models with elastic, hyperelastic and porohyperelastic properties showed similar behavior throughout the stance, while the model with FRPHE properties exhibited lower joint forces during the last 50% of the stance phase. ...

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. ...

Weight-bearing MRI of the knee: a review of advantages and limits.
Bruno F, et al. Acta Biomed 2018 - Review. PMID 29350638 Free PMC article.
Standard knee imaging with MRI is usually performed with patient in recumbent position under non-weight-bearing conditions. Recently, magnetic resonance imaging systems to scan the knee joint under weight bearing conditions has been proposed as an approach to improve the clinical utility of musculoskeletal MRI. Imaging under loading can be useful to understand the natural motion behavior of the knee joint and to identify conditions that are challenging to diagnose by using standard position. ...

Novel knee joint mechanism of transfemoral prosthesis for stair ascent.
Inoue K, et al. IEEE Int Conf Rehabil Robot 2013. PMID 24187254
This difficulty is mainly due to insufficient generation of extension moment around the knee joint of the prosthesis to lift the body to the next step on the staircase and prevent any unexpected flexion of the knee joint in the stance phase. ...Therefore, the purpose of this research is to develop a novel knee joint mechanism for a prosthesis that generates an extension moment around the knee joint in the stance phase during stair ascent, without the use of any actuators. ...

The knee meniscus: structure-function, pathophysiology, current repair techniques, and prospects for regeneration.
Makris EA, et al. Biomaterials 2011 - Review. PMID 21764438 Free PMC article.
Extensive scientific investigations in recent decades have established the anatomical, biomechanical, and functional importance that the meniscus holds within the knee joint. As a vital part of the joint, it acts to prevent the deterioration and degeneration of articular cartilage, and the onset and development of osteoarthritis. ...
