Dynamic Knee Alignment and Collateral Knee Laxity and Its Variations in Normal Humans

Dynamic Knee Alignment and Collateral Knee Laxity and Its Variations in Normal Humans

Alignment of normal, arthritic, and replaced human knees is a much debated subject as is the collateral ligamentous laxity. Traditional quantitative values have been challenged. Methods used to measure these are also not without flaws. Authors review the recent literature and a novel method of measurement of these values has been included. This method includes use of computer navigation techniq...

Dynamic alignment and its association with knee adduction moment in medial knee osteoarthritis.

Lower limb dynamic alignment represents the limb position during functional loading conditions and obtains valuable information throughout the gait cycle rather than a single instant in time. This study aims to determine whether dynamic alignment is altered in medial knee osteoarthritis (OA) and how dynamic alignment is related to knee adduction moment (KAM). Community-dwelling women (n=17) wit...

Cyclic variations in multiplanar knee laxity influence landing biomechanics.

PURPOSE Females vary substantially in their multiplanar cyclic knee laxity changes across the menstrual cycle. The biomechanical implications of these cyclic changes are relatively unknown. Our purpose was to first cluster females based on their cyclic changes in anterior knee laxity (AKL), genu recurvatum (GR), varus-valgus (VV), and internal-external (IER) rotation knee laxity across the mens...

Variations In Femoral Anteversion And Tibial Torsion Influence Knee Alignment In Subjects With Knee Osteoarthritis

Knee Laxity or Loss of Knee Range of Motion after PCL Reconstruction: A Systematic Review and Meta-Analysis

Background. PCL reconstruction is a successful method for enhancing the patientchr('39')s quality of life but posterior knee laxity and knee stiffness have still occurred surgery. There is no study to evaluate knee laxity or loss of knee range of motion after surgery. Objectives. To assess the outcomes after PCL reconstruction, we: 1) evaluated the range of motion of the knee, 2) evaluated pos...
