Locking plates for distal femur fractures does an increased working length improve healing?
Distal femur locking plates have become a very popular means of internal fixation because of their ability to provide stable distal periarticular fixation. In spite of this enthusiasm however several studies have reported significant problems with healing. In the distal femur it is recognized that …

Changes in 3 Dimensional Microstructures of Subchondral Cancellous Bone of Distal Femur in Early Osteoarthritis
… bone cores were obtained from 4 parts of distal femur of 13 Korean cadaver donors. 6 donors had only grade 2 or 3 cartilage changes in distal part of medial femoral condyle and 7 donors had normal cartilage. These specimens were scanned using high-resolution micro-computed tomography and 3 …

Numerical and experimental studies on the mechanical behaviour of the distal femur following total knee arthroplasty
… presents finite element (FE) models of the distal femur following primary and revision total knee arthroplasty. Pre-arthroplasty models are also developed for comparison. Particular attention is given to how femoral component design and method of fixation impacts the mechanical environment …

A Biomechanical Analysis of One-Third Tubular Plates for the Treatment of Benign Lesions in the Distal Femur
… the treatment of benign defects in the medial distal metaphysis of the femur. Benign cysts are a common occurrence in long bones, and are of concern in load-bearing bones, such as the tibia and femur. These space-occupying growths are removed by curettage of the affected region. Numerous …

Finite element analysis of total knee replacement considering gait cycle load and malalignment
… software. Stress shielding was found in the distal femur in the implanted knee joint. The stresses and strains in the distal femur were found to increase with body weight, especially during the stance phase. Serious stress shielding and more bone loss appear in condition of overweight. The …

The effect of continuous infusion of human parathyroid hormone on bone architecture in female mice
… bone microarchitecture. Trabecular bone in the distal femur as well as the L5 vertebrae was also largely preserved. This data indicate that short term infusion of PTH in normal mice does not mimic clinical characteristics and therefore may not be an appropriate model of secondary …

The Effect of Stifle Angle on Stifle Kinematics following TPLO: An in vitro Experimental Analysis
… motion tracking sensors were placed on the distal femur and proximal tibia. A force was applied at approximately 10 N/sec to mimic the action of the quadriceps muscle. Force application allowed the limb to move from 120° to maximal extension. Positional data was acquired at 60 points/second. …

Localizing longitudinal changes in volumetric bone mineral density after acute knee injury using voxel-based morphometry
… ACL injury. Population-based atlases of the distal femur, proximal tibia, and patella were developed to facilitate voxel-wise comparisons. The precision of BMD measurements was evaluated both globally and locally, demonstrating excellent global reproducibility with localized variability at …

In Vitro Investigations of Conventional vs. Robotic-Assisted Total Knee Arthroplasty
… This procedure removes diseased tissues from the distal femur and proximal tibia, replacing them with prostheses. Traditionally, manual tools, cutting guides, and sizing jigs determine cut positioning and implant orientation. However, persistent patient dissatisfaction and revision rates highlight …

Effectiveness of surgical versus conservative treatment for distal femoral growth plate fractures: a systematic review
Injury to the distal femoral growth plate in children is typically due to a high-energy trauma such as contact sports or motor vehicle accidents. There is no clear evidence as to whether surgery or application of a plaster or splint is the best option for these injuries in terms of growth arrest …

Finite Element Modeling and Validation of the Patellofemoral Joint
… patella, a flat, rounded triangular bone, the distal part of the femur, which forms an inverted U-shaped intercondylar groove, and the articular cartilage that covers both the distal femur and posterior patella. Articular cartilage has several functions to enhance functionality in this joint …

The role of the bone marrow niche and G-CSF in osteochondral repair
… groove and penetrated 1205 (± 58.6) µm into the distal femur. The coefficient of variation (CV) for each parameter was below 6%. The area of injury demonstrated regenerated articular cartilage, an observation not previously described in the typically poor healing C57Bl/6 strain of mice. Further, …

Knöcherne Integration und Biokompatibilität eines neuen resorbierbaren Polymers zur Schraubenaugmentation im osteoporotischen Knochen
… were implanted in the cancellous bone in the distal femur and proximal tibia in both groups. The screws were fixed in the bones with variations of the new bone cement. In each group, three screw fixation techniques were investigated: augmented with the new polymers, augmented with PMMA, or not …
