| The most common views are the anteroposterior, lateral and axial patellar images to assess for fracture, dislocation and effusion. |
| The quadriceps muscles act on the knee through the quadriceps and patellar tendons. |
| In the normal contralateral patellar tendons, ultrasonographic morphologic changes were not seen. |
| The most common fracture was patellar fracture, followed by fractures of the tibial spine and proximal tibia. |
| The capsule also is reinforced in front by the patellar and quadriceps tendons and posteriorly by the popliteus and gastrocnemius muscles. |
| Routine closure was performed with closure of the patellar peritenon in the patellar tendon group. |
