The commonest cyst to occur in the popliteal region is the popliteal cyst and over the past years it has received much clinical attention. The commonest position of the popliteal cyst is in the posterosuperior aspect of the medial femoral condyle. The present case report describes a rare case of popliteal cyst, which was found on the postero-superior aspect of the lateral condyle of the femur. ...

BACKGROUND Lubricin, a mucinous glycoprotein secreted by synoviocytes and chondrocytes plays an important role in reducing the coefficient of friction in mammalian joints. Elevated cartilage surface friction is thought to cause chondrocyte loss; however, its quantification and methodological approaches have not been reported. We adapted a stereological method and incorporated vital cell stainin...

Avascular necrosis of the femoral condyle is an uncommon but serious sequela in patients who have received chemotherapy or corticosteroid treatment. The optimal treatment of avascular necrosis of the femoral condyles in pediatric patients is not well established. Nonoperative management has had limited long-term success, and many of the surgical procedures available for adults, including core d...

BACKGROUND Recent data suggest magnetic resonance imaging (MRI) is the best method to analyze the status of the cartilage and subchondral bone in patients with juvenile osteochondritis dissecans (JOCD). METHODS MRI analysis of 122 knees and 132 JOCD lesions in 109 patients who underwent arthroscopic treatment for osteochondritis dissecans lesions of the knee between March 2003 and January 201...

The purpose of this study was to investigate in vivo three- dimensional tibiofemoral kinematics and femoral condylar motion in knees with anterior cruciate ligament (ACL) deficiency during a knee bend activity. Ten patients with unilateral ACL rupture were enrolled. Both the injured and contralateral normal knees were imaged using biplane radiography at extension and at 15°, 30°, 60°, 90°, and ...

The principal purpose of this prospective study was to examine intercondylar notch size and the value of inner angle of lateral femoral condyle as the risk factors for noncontact anterior cruciate ligament ACL injury and than to correlate them to the physical values of the athletes such as body mass index (BMI), hight, wight, etc. There are indentified two type of risk factors, external include...

Background: Acquiring knowledge about anatomic and geometric quantities of bones is among the most vitalparameters in orthopedic surgery that has a significant effect on the treatment of various disorders and subsequentoutcomes. The aim of this study was to obtain anthropometric information for distal femur in order to compare withsimilar dimensions of prosthesis used in total...

BACKGROUND Understanding the relationship between the radii of the medial and lateral femoral condyles in varus and valgus knees is important for aligning the femoral component and for restoring kinematics in total knee arthroplasty. The purpose of this study was to test the hypothesis that the asymmetry between the radii of the medial and lateral femoral condyles in varus and valgus knees with...

BACKGROUND CONTEXT Occipital condyle screws appear to be a novel technique that demands biomechanical consideration. It has the potential to achieve fixation anterior to the axis of rotation while offering a point of fixation in line with the C1/C2 screws. PURPOSE To compare the segmental stability and range of motion (ROM) of standard occipitocervical (OC) screw/rod and plate constructs vers...
