Background: Posterior tibial slope (PTS) is an important factor in the knee joint biomechanics and one of the bone features, which leads to knee joint stability. Posterior tibial slope affects flexion gap, knee joint stability and posterior femoral rollback that are related to wide range of knee motion. During high tibial osteotomy and total knee arthroplasty (TKA) surgery, proper retaining the...

Mechanical loading during physical activity produces strains within bones. It is thought that these forces provide the stimulus for the adaptation of bone. Tibial strains and rates of strain were measured in vivo in six subjects during running, stationary bicycling, leg presses and stepping and were compared with those of walking, an activity which has been found to have only a minimal effect o...

Tibial shaft fractures are typically the result of high-energy injuries, however bone that has been substantially weakened may be susceptible to fractures without a preceding traumatic incident. Such bone weakening may occur secondary to malignant disease but also in chronic conditions such as Paget's disease. The altered structural properties of Pagetic bone and cellular changes including incr...

Aseptic loosening of the tibial component is the major complication of total knee arthroplasty. There is an association between early excessive shear micromotion between the bone and the tray of the tibial component and late aseptic loosening. Using non-linear finite element analysis, whether a tibial tray with a circumferentially flanged rim and a mating cut in the proximal tibia could minimiz...

conclusions we feel this rare, currently unclassified variant of a tibial tubercle avulsion fracture should be recognised and consideration taken to adding it to existing classification systems. introduction a sleeve fracture classically describes an avulsion of cartilage or periosteum with or without osseous fragments and usually occurs at the inferior margin of the patella. tibial tubercle sl...

PURPOSE To compare 2 methods of fixation for maintenance of alignment during healing of valgus tibial osteotomies. METHODS We performed a retrospective chart and radiographic review of valgus tibial osteotomy cases of staple fixation supplemented by a postoperative cast and of blade plate fixation for maintenance of femoral-tibial alignment during healing of the osteotomy. RESULTS Both grou...

The purpose of this study was to evaluate and compare the intrusion characteristics of Simplex-HV to Simplex-P and Palacos-R in cadaveric proximal tibial bone. Eighteen fresh-frozen cadaver proximal tibiae were examined with standard arthroplasty tibial cuts. Each tibia was randomly assigned to receive one of the three bone cements for use with finger packing technique. Sagittal sections were p...

Background:Tibial fractures are the most common long bone fracture, with approximately 25% being open. The majority of open tibial result from a high velocity trauma, such as motorcycle accident, or low energy, torsional type injury, skiing. They complex to treat because lack soft tissue coverage and blood supply shaft. Aim: To determine functional outcome hybridillizarov technique in patients ...

BACKGROUND Little is known about the time course of changes in the microarchitecture of the tibial epiphysis with rheumatoid arthritis (RA), although such information would be valuable in predicting risk of fracture. Therefore, we used in vivo microcomputed tomography (μ-CT) to assess patterns of microarchitectural alterations in the tibial epiphysis using collagen-induced RA in an animal model...
