Posterior cruciate ligament recruitment affects antero-posterior translation during flexion gap distraction in total knee replacement

BACKGROUND AND PURPOSE Because of the oblique orientation of the posterior cruciate ligament (PCL), flexion gap distraction could lead to anterior movement of the tibia, which would influence the tibiofemoral contact point. This would affect the kinematics of the TKR. We assessed the flexion gap parameters when the knee is distracted during implantation of a PCL-retaining TKR. Furthermore, the ...

Assessment of Antero-Posterior Skeletal and Soft Tissue Relationships of Adult Indian Subjects in Natural Head Position and Centric Relation

BACKGROUND The aim of this study was to verify the intra-individual reproducibility of natural head position (NHP) in centric relation (CR) position, to prove the inter-individual differences in the Frankfort horizontal plane and sella-nasion line compared with the true horizontal line, and to establish linear norms from A-point, B-point, Pog as well as soft tissue A-point, soft tissue B-point,...

Antero-posterior and vertical facial type variations influence the aesthetic preference of the antero-posterior lip positions.

UNLABELLED SummaryObjectives: The purposes of this study were to investigate whether the antero-posterior and vertical facial type variations influenced the favoured lip positions and to elucidate whether the favoured lip positions differed between orthodontists and laypersons. METHODS An average profile was constructed from a Japanese female with Class I occlusion and a well-balanced profile...
