Independent Medical Examinations provide attorneys, insurers, employers, and claims professionals with an objective assessment of complex orthopedic conditions. An orthopedic IME may address diagnosis, medical causation, treatment, prognosis, impairment, functional limitations, and the significance of pre-existing conditions.
Independent Medical Examinations (IMEs) can provide attorneys, insurers, employers, and claims professionals with an independent medical assessment of an individual’s orthopedic condition. In Oklahoma matters involving musculoskeletal injuries, an orthopedic IME may help clarify questions about diagnosis, treatment, medical causation, prognosis, impairment, and functional limitations.
MedLegal Authority is an orthopedic expert-witness and Independent Medical Examination practice based in the Oklahoma City area and serving clients throughout Oklahoma. Led by board-certified, fellowship-trained orthopedic surgeon Dr. J. Calvin Johnson, MD, MLA provides objective orthopedic evaluations and medical analysis for legal and insurance matters.
An Independent Medical Examination is a medical evaluation performed by a physician who is asked to provide an independent assessment rather than ongoing treatment.
In an orthopedic IME, the physician may review medical records, obtain an appropriate history, perform a physical examination, consider relevant diagnostic information, and develop medical opinions based on the available evidence and the questions presented for the assignment.
Depending on the circumstances, an orthopedic IME may address issues such as:
The purpose is not to provide legal advice or determine the outcome of a claim. An IME provides medical expertise that attorneys and claims professionals may use alongside other evidence in evaluating a matter. MedLegal Authority is not a law firm and does not provide legal representation, legal strategy, or legal services.
Orthopedic IMEs may be appropriate when important medical questions remain unresolved or require an independent assessment.
For example, an attorney or claims professional may need additional medical analysis when the record contains multiple diagnoses, differing descriptions of an injury, an extended course of treatment, pre-existing orthopedic conditions, questions about ongoing restrictions, or uncertainty about prognosis.
MedLegal Authority’s approved areas of analysis include orthopedic injury evaluation, treatment, prognosis, impairment, functional limitations, medical causation, workers’ compensation evaluations, personal-injury medical evaluations, and insurance or disability dispute evaluations.
An IME does not replace the role of a treating physician. The two physicians generally serve different purposes. A treating physician focuses on the patient’s clinical care, while an independent medical examiner is asked to evaluate defined medical questions objectively based on the examination, records, and available evidence.
The scope of an IME depends on the assignment and the medical questions presented. In an orthopedic matter, the evaluation may involve several areas.
The examiner may assess the orthopedic diagnoses documented in the medical record and compare them with examination findings, imaging, prior treatment, and other available medical information.
Causation analysis considers whether an orthopedic condition is medically related to a reported event or injury.
This analysis can become particularly important when a person has degenerative changes, prior injuries, previous treatment, or other medical factors that may overlap with the condition being evaluated.
A well-supported causation opinion should distinguish between temporal association—something occurring after an event—and a medically supported relationship based on the available evidence.
An orthopedic reviewer may evaluate the course of treatment documented in the records and consider how it relates to the diagnosed condition, objective findings, reported symptoms, and expected clinical course.
The focus is medical rather than legal: what treatment occurred, what the medical evidence shows, and how that treatment relates to the orthopedic condition under review.
Prognosis concerns the expected future course of an injury or condition. Depending on the available evidence, the physician may address expected recovery, persistent symptoms, future limitations, or whether additional orthopedic care may be medically anticipated.
Impairment and function are related but distinct concepts.
Impairment generally refers to a medically assessed loss or abnormality involving a body structure or function. When an assignment calls for an impairment rating, MLA may use the applicable AMA Guides when confirmed for that specific assignment.
Functional limitations concern what activities an individual can or cannot reasonably perform because of the orthopedic condition.
Keeping these concepts separate can help attorneys and claims professionals understand what the medical evidence actually supports.
The medical record often provides the foundation for an orthopedic IME.
Records may document the condition before an alleged injury, the initial presentation, diagnostic testing, treatment decisions, response to treatment, later complaints, and changes in function over time. They may also contain inconsistencies or gaps that require clarification.
A structured review can help the examining physician distinguish among:
The goal is not simply to summarize the chart. It is to understand how the medical evidence fits together and what conclusions can reasonably be supported from an orthopedic perspective.
The appropriate materials will vary by matter, but a complete and organized medical file can make the evaluation more efficient and medically useful.
Relevant materials may include prior and subsequent orthopedic records, imaging reports, operative records when applicable, therapy records, diagnostic studies, medication histories, work-status documentation, and other medical information relevant to the condition being evaluated.
Attorneys and claims professionals should also clearly identify the medical questions they would like addressed. Focused questions can help define the scope of the evaluation without directing the physician toward a predetermined conclusion.
Independence is grounded in methodology rather than in which party retained the physician.
A medically independent evaluation should apply the same analytical approach regardless of whether the request comes from a plaintiff attorney, defense attorney, insurer, employer, or another appropriate party.
For MedLegal Authority, the preferred approach emphasizes objective orthopedic analysis, balanced review, consistent methodology, and opinions based on medical evidence rather than the retaining party. MLA works with both plaintiff and defense matters and is positioned as a neutral source of orthopedic medical expertise.
That neutrality is particularly important when medical records contain competing explanations for symptoms or when causation, prognosis, impairment, or functional capacity is disputed.
When selecting an orthopedic physician for an IME, relevant considerations may include specialty training, clinical experience, experience reviewing complex medical records, familiarity with the orthopedic conditions involved, and the ability to communicate medical findings clearly.
Dr. J. Calvin Johnson is a board-certified, fellowship-trained orthopedic surgeon and founder of MedLegal Authority. He completed medical school and orthopedic surgery residency training through the University of Oklahoma and later completed a sports-medicine fellowship at Rush Presbyterian–St. Luke’s Medical Center in Chicago, with an emphasis on knee and shoulder surgery.
Dr. Johnson brings more than 35 years of orthopedic experience, including 25,000+ procedures performed and 1,000+ Independent Medical Examinations completed. His current professional work focuses on IMEs, orthopedic medical-record reviews, reports, depositions, testimony, and independent medical analysis.
MedLegal Authority identifies spine, shoulder, and knee conditions among its primary orthopedic focus areas.
Depending on the assignment, the examining physician may prepare a written report explaining the records reviewed, examination findings, relevant orthopedic issues, and medical opinions.
A useful report should make the reasoning understandable. Rather than simply announcing a conclusion, it should connect the available medical evidence to the opinion being expressed.
When appropriate to the engagement, MLA may also provide expert-witness consulting, depositions, and testimony concerning orthopedic medical issues.
The physician’s role remains medical: to explain orthopedic evidence and provide professionally supported opinions, not to advocate for a particular legal outcome.
An IME can be particularly valuable when a large medical record needs to be converted into a clear clinical analysis.
For example, a generalized orthopedic matter might involve a documented pre-existing condition followed by a new injury and continuing symptoms. The medical question may not be whether abnormalities exist—they may be well documented—but rather which findings are pre-existing, which findings may relate to the more recent event, and what functional consequences are medically supported.
An independent orthopedic evaluation can organize those issues around the available evidence and explain where the medical record supports a conclusion, where uncertainty remains, and which factors are relevant to causation, prognosis, or function.
That distinction can make complex orthopedic information easier for non-physicians to understand without turning the medical expert into an advocate for either side.
No. An IME is performed for independent medical evaluation rather than ongoing clinical treatment. A treating physician and an independent medical examiner generally have different roles.
Yes. Medical causation analysis is one of MLA’s approved services. Depending on the medical evidence, an orthopedic physician may evaluate whether and to what extent a condition is medically associated with a reported injury or event.
Yes. Prior orthopedic conditions can be relevant to understanding diagnosis, causation, prognosis, impairment, and function. The physician may compare pre-event and post-event medical evidence when sufficient records are available.
Yes. MLA may assess orthopedic impairment and functional limitations as part of an appropriate assignment. Impairment ratings using applicable AMA Guides may also be provided when confirmed for the engagement.
No. MLA maintains neutral positioning and works with both plaintiff and defense matters. Its stated methodology emphasizes objective orthopedic analysis and conclusions based on medical evidence rather than the retaining party.
No. MedLegal Authority is an orthopedic expert-witness and Independent Medical Examination practice, not a law firm. MLA provides independent orthopedic medical expertise but does not provide legal advice, representation, strategy, or other legal services.
MedLegal Authority is based in the Nichols Hills/Oklahoma City area and serves clients throughout Oklahoma. Matters beyond Oklahoma may be considered when confirmed as appropriate by MLA.
