Outcome Analysis of Posterior Cruciate Ligament Injuries: A Narrative Review.

The primary posterior stabilizer of the knee is the posterior cruciate ligament (PCL), the largest intra-articular ligament in the human knee. One of the four primary ligaments of the knee joint, the PCL, serves to support the tibia on the femur. An extreme force applied anteriorly to the proximal tibia of the flexed knee results in trauma to the PCL.

Chondroblastoma of proximal tibia diagnosed by arthroscopy-guided biopsy: a case report.

Chondroblastoma considered a rare form of osseous neoplasm contributes less than 1% of all bone tumours. It is typically found in young patients with chief complaints of moderate pain with joint stiffness. It develops as a lytic lesion in the epiphysis of long bones which might spread to the metaphysis.

Abnormal Presentation of Extrapulmonary Tuberculosis.

Tuberculosis is a common bacterial infection that mainly affects the respiratory system; however, it can involve other structures such as lymph nodes, pericardium, pleura, central nervous system, gastrointestinal system, and skeletal system. Skeletal tuberculosis is secondary to pulmonary and abdominal tuberculosis. Skeletal involvement generally involves the vertebral column, hip, and knee joint.

Thoracolumbar Extramedullary Myxopapillary Ependymoma: A Rare Case.

An intradural extramedullary myxopapillary ependymoma is a rare spinal cord tumor found in the thoracolumbar region of the spine. In this case report, we describe this case and review the various aspects of ependymomas. There are different types of ependymomas based on their location and histopathological appearance.

Aneurysmal Bone Cyst of the Head of the Fibula: An Unusual Presentation.

Bone cysts are tumor-like lesions of bone. These are primarily of two types: simple or unicameral and aneurysmal bone cysts (ABC). An aneurysmal bone cyst (ABC) is a blood-filled cyst that usually occurs over the metaphysis of long bones, flat bones, and vertebrae.
