Ligamentous injuries of the knee occur in the military, but constitute an overwhelmingly disproportionate number of medical discharges, which can be due to prolonged recovery through traditional use of physical therapy (PT) and other non-operative modalities. The use of platelet-rich plasma (PRP) may substantially increase the speed of recovery and patient outcomes but is little explored for less common isolated ligamentous injuries, such as the lateral collateral ligament, especially in active-duty populations. We describe the use of PRP in a young, otherwise healthy active-duty male to treat an isolated LCL injury with significant positive outcomes. These findings support consideration for early use of PRP in similar cases to improve recovery timelines and aid in return to duty.
