Assignment - Research Proposal Example Posterior cruciate ligament (PCL) injuries are the most rare injuries.(1- JM) Most suspected knee disorders become diagnosed first through conventional radiographs (X-rays). These radiographs are effective in demonstrating fractures because the show bones and joint spaces. Their sensitivity to soft tissue conditions remains low except in conditions where the tissues contain mush calcium or fat. X-rays are also relatively insensitive to destruction of medullary bone and loss of cartilage as well. The basic examination consists of lateral and ante posterior (AP) projections of the knee.(Carmen MartÄ ±Ã‚ ´n-Herva ´s) Radiographs and CTs remain effective modalities for post-operative imaging following ACL reconstruction. CTs, however, depict femoral tunnel in more accurate manner than radiographs. The radiation dosage however, is almost double that of the radiographs and this should be effective considered when utilizing CTs over radiographs ( Anagha et al). Plain radiographs provide limited assistance in dealing with sports related injuries. They can only be indicated in circumstances where there is significant impact injury. Positive findings are however, occasionally demonstrated in ACL disruptions, where there is depression of the lateral femoral notch, and segond fracture. Computed Tomography (CT) provides effective analysis for categorizing fracture of the tibia plateau. Ultrasound imaging is utilized minimally together with magnetic resonance imaging when analyzing many knee injuries. Ultrasound becomes reliable in assessment of quadriceps and patellar tendons, when symptoms of injury are located within the anterior joint, and are focal. Ultrasound easily identifies collateral ligaments. Injuries to these ligaments are however associated with derangement and MRI becomes essential in demonstrating the full spectrum of the injury (12- EUGENE G). MRI utilizes high soft tissue contrast and multiplanar capability in
