BACKGROUND Multi-planar proximal tibial slopes may be associated with increased likelihood of osteoarthritis and anterior cruciate ligament injury, due in part to their role in checking the anterior-posterior stability of the knee. Established methods suffer repeatability limitations and lack computational efficiency for intuitive clinical adoption. The aims of this study were to develop a nove...

The posterior tibial slope (PTS) plays an immensely important role in almost every orthopaedic operation on the knee joint. PTS is a decisive factor reconstruction of torn anterior or cruciate ligament, high osteotomy and, course, total arthroplasty. It therefore all more surprising that current clinical practice relatively little emphasis placed exact measurement PTS. If true value not known, ...

The relationship between impingement of the roof of the intercondylar notch on a reconstructed anterior cruciate ligament, and the subsequent stability and range of extension of the joint, was analyzed in fortyseven knees. The extent of the impingement was determined by analysis of the relationship of the tibial tunnel to the intersection of the line of slope of the intercondylar roof with the ...
