A motion-analysis study of professional ballet dancers revealed that the repetitive motion of dance and relative soft-tissue laxity allowed the dancers to place their hips in impinging positions, despite not having any anatomic predisposition towards FAI.
Proportional Distribution of Job Laxity Algorithm.
Many studies have shown significantly greater translational and rotational laxity of the reconstructed knees relative to the contralateral uninjured sides, regardless of the graft type.
It is possible that signs of anterior translation of the tibia relative to the femur are associated with high-grade laxity after ACL injury; however, even in cases with high-grade ACL injury, anterior translation of the tibia would not be easy to discern because standard MRI is performed with the patient in the supine position.
Multifactorial sensitivity analyses were performed to assess the relative influence of these surgical factors on the intraoperative joint laxity, graft-tunnel contact mechanics and graft forces.
On a more prosaic level, the data highlights the apparent laxity and sloth of the UK legal and tax authorities relative to other countries.
Anterior translation of the tibia relative to the femur was the only secondary finding associated with high-grade laxity on physical examinations in the present study.
Furthermore, bone contusions, a Segond fracture, the deep sulcus sign, a decreased posterior cruciate ligament (PCL) angle, and the anterior translation of the tibia relative to the femur are secondary findings that may be related to knee joint laxity: the first three may reflect the severity of the injury, while the latter two may be caused directly by the anteriorly displaced tibia.
With regards to the relative palpebral continence, the reduction should be approximately 3 mm but needs to be greater if the patient has major tarsal laxity or clinically manifest ectropion.
The relative increase of the rate of midflexion instability from 50th TKR on was probably caused by the surgeon adding a little laxity after seeing some knees with a limited range of motion in too-tight implantations in the early phase.
