Treatment of proximal tibial defects is important to the survival of tibial prosthesis after total knee replacement. The objective of this finite element study was to determine a better understanding of the stresses produced by different treatment options for moderate uncontained type-2 defects. Methods analysed were the use of metal wedges, metal blocks, cement wedges, and cement blocks for th...

BACKGROUND Genicular nerve block has recently emerged as a novel alternative treatment in chronic knee pain. The needle placement for genicular nerve injection is made under fluoroscopic guidance with reference to bony landmarks. OBJECTIVE To investigate the anatomic landmarks for medial genicular nerve branches and to determine the accuracy of ultrasound-guided genicular nerve block in a cad...

Currently, the most common method for drilling the femoral tunnel in anterior cruciate ligament reconstruction (ACLR) employs a trans-tibial technique. A new technique, utilising anteromedial portal drilling has been shown to produce a more anatomical placement of the femoral tunnel than trans-tibial (1). A further recent development is the concept of anatomical anterior cruciate ligament recon...

BACKGROUND Internal-external (I-E) malrotation of the tibial component is associated with poor function after total knee arthroplasty (TKA). Kinematically aligned (KA) TKA uses a functionally defined flexion-extension (F-E) tibial reference line, which is parallel to the F-E plane of the extended knee, to set I-E rotation of the tibial component. METHODS Sixty-two, three-dimensional bone mode...

PURPOSE OF THE STUDY When a larger opening of high-tibial osteotomy is necessary to achieve good correction of the lower extremity axis, partial release of the attachments of the medial stabilisers of the knee may be required. The aim of the study was to ascertain, in cadaver specimens, the effect of loosening the medial knee stabilisers on the magnitude of correction in medial opening-wedge hi...

BACKGROUND/AIM The tibial slope is one of the most frequently cited anatomical causes of anterior cruciate ligament trauma. The aim of this study was to determine the possibility of direct measuring of the tibial slope of the knee without prior soft tissue dissection in cadavers. METHODS Measurement was performed on the two groups of samples: osteological and cadaveric. The osteological group...

AIMS Knowledge about branching pattern of the popliteal artery is very important in any clinical settings involving the anterior and posterior tibial arteries. This study aims to elucidate the anatomical variation patterns and common types of anterior tibial artery (ATA) and posterior tibial arteries (PTA) in the general population in China. MATERIAL AND METHODS Anatomical variations of ATA, ...

This study tested the validity of the prediction of dynamic knee loads based on gait measurements. The relationship between the predicted loads at the knee and the distribution of bone between the medial and lateral sides of the tibia was examined. The motion and external forces and moments at the knee were measured during gait and a statically determinate muscle model was used to predict the c...

BACKGROUND Posttraumatic osteoarthritis (PTOA) is secondary to an array of joint injuries. Animal models are useful tools for addressing the uniqueness of PTOA progression in each type of joint injury and developing strategies for PTOA prevention and treatment. HYPOTHESIS Intra-articular fracture induces PTOA pathology. STUDY DESIGN Descriptive laboratory study. METHODS Through a parapate...

OBJECTIVE To study the anatomy of the posterior cruciate ligament (PCL) and define anatomical parameters with the knee flexed at 90°. METHODS Eight knees from cadavers were dissected in order to make measurements from the center of the anterolateral band to the roof (AL1), from the center of the anterolateral band to the anterior cartilage (AL2), from the center of the posteromedial band to t...
