Sports Medicine Legal & Expert Witness Services

At Baseline Sports & Performance Medicine, we provide clear, evidence-based medical opinions in sports and musculoskeletal medicine.
Dr. Jason M. Matuszak combines clinical experience, academic leadership, and national sports medicine policy expertise to deliver objective analysis for both plaintiff and defense cases. Our mission is simple: help legal teams understand the medical facts — not just the medical jargon.

  • We offer thorough, timely, and impartial evaluation of medical records, imaging, and documentation related to sports injuries and athletic participation.
    Our reviews include:

    • Analysis of injury mechanisms and treatment timelines

    • Review of standard-of-care compliance

    • Identification of gaps in documentation or communication

    • Concise written summaries for counsel use

  • When expert testimony is required, clarity and credibility matter most.
    We prepare comprehensive reports and provide deposition and trial testimony focused on medical accuracy, educational clarity, and transparency.
    Dr. Matuszak’s testimony emphasizes objective interpretation of evidence, presented in a way that judges, juries, and mediators can easily understand.

  • Concussion cases demand both clinical insight and policy awareness.
    We specialize in clarifying the medical standards that govern diagnosis, management, and clearance decisions in youth, collegiate, and professional athletics.
    Our services include:

    • Review of concussion recognition and assessment procedures

    • Return-to-Play and Return-to-Learn protocol evaluation

    • Analysis of sideline documentation and communication practices

    • Interpretation of policy compliance and deviation impact

    Our experience bridges hands-on clinical care and authorship of national sports medicine consensus statements.

  • Not every matter requires formal testimony. We partner with attorneys, risk managers, and insurers to provide behind-the-scenes expertise including:

    • Pre-litigation merit reviews

    • Standard-of-care interpretation

    • Medical literature summaries

    • Strategic guidance for case direction and expert selection

    This flexible model helps legal teams assess the medical landscape early and make informed decisions about case viability.
