Study summary

Knee immobilization in near extension has been proposed as a nonoperative treatment for primary traumatic patellar dislocation, although there exist no prospective studies regarding the method of immobilization. The objective of this prospective randomized study was to compare the clinical outcome after nonoperative treatment with restricted vs. free range of motion (ROM) for primary traumatic patellar dislocation.
