Abstract:
Agenesis of the posterior cruciate ligament (PCL) is a rare disorder often found in conjunction with various other abnormalities within the knee. A 15-year-old adolescent boy presented with an absent PCL, leading to intermittent symptoms. At the age of 20 years, the patient underwent arthroscopically assisted PCL reconstruction. The patient was permitted to weightbear immediately after the procedure and started physical therapy 4 weeks after the procedure. No complications were encountered at the 2-year follow-up.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
