Traumatic Mid-substance Isolated Vastus Medialis Rupture in a Young Athlete: A Case Report

Area of Science:

• Sports Medicine
• Orthopedic Surgery
• Regenerative Medicine

Background:

• Isolated traumatic vastus medialis ruptures are exceedingly rare, particularly in adolescent athletes.
• Mid-substance tears of the quadriceps present complex treatment challenges.
• Direct impact injuries can lead to unique musculotendinous disruptions.

Observation:

• A 14-year-old athlete sustained an isolated mid-substance vastus medialis rupture following direct impact during sports.
• Diagnostic imaging confirmed the rare nature of this specific injury.
• The patient's injury was managed conservatively.

Findings:

• Conservative management, including physical therapy, was augmented with blood flow restriction therapy (BFRT) and platelet-poor plasma (PPP) injections.
• This multimodal nonoperative approach facilitated complete functional recovery.
• The patient achieved an early return to athletic activity.

Implications:

• This case highlights the potential efficacy of BFRT and PPP in managing rare quadriceps mid-substance tears.
• Nonoperative strategies can be successful for isolated vastus medialis ruptures in young athletes.
• Further research into regenerative therapies for traumatic muscle injuries is warranted.
