ABPMR Sports Medicine common mistakes
ABPMR Sports Medicine · Understand the traps and how to avoid them.
On an acute knee hemarthrosis vignette, selecting ACL tear as the sole diagnosis and omitting patellar dislocation, osteochondral fracture, and meniscal tear from the differential.
Classic pattern recognition and test-taking momentum: acute hemarthrosis is taught as ACL until proven otherwise, and vignettes often bury a competing finding such as a laterally displaced patella or a loose body.
What to do instead
Before answering, force a three-item differential for every joint vignette and match discriminating findings (patellar apprehension, Lachman, McMurray, effusion timing); apply the Ottawa knee rules when trauma is described.
Evaluating every young athlete with groin pain as femoroacetabular impingement or labral tear and omitting lumbar spine, sacroiliac joint, adductor, iliopsoas, and abdominal wall sources.
Recent emphasis on hip arthroscopy creates availability bias, and groin pain is a regional problem with overlapping provocation tests.
What to do instead
Use a regional groin-pain checklist and interpret multiple provocative tests (FADIR, FABER, adductor squeeze, resisted hip extension, cough impulse) before committing to a hip-joint diagnosis.
Clearing an athlete with hypertrophic cardiomyopathy, unexplained exertional syncope, or a family history of sudden cardiac death because the physical examination and resting ECG look normal.
Normal resting tests falsely reassure, and candidates underweight the history elements that drive eligibility decisions.
What to do instead
Treat exertional syncope and a family history of sudden death before age 50 as red flags requiring cardiology evaluation; memorize sport-eligibility categories for HCM, Long QT, WPW, and myocarditis.
Miscomputing workload from exercise-test stage and time, or calling a test positive without checking for confounders such as LBBB, digoxin effect, or LVH.
Protocol tables are memorized superficially, and the report is read as positive or negative without verifying effort or ST-segment interpretability.
What to do instead
Memorize Bruce stages (approximately 5, 7, 10, and 13 METs), confirm maximal effort (HR at least 85% predicted, RER at least 1.1), and state when ST segments are non-diagnostic.
Completing a preparticipation evaluation with only a general physical and no cardiovascular, concussion, sickle cell, heat-illness, or mental-health screening.
Time pressure and the misconception that the PPE is merely a clearance physical lead candidates to answer from the vignette rather than a structured history.
What to do instead
Run the AHA 14-element checklist and PPE monograph domains explicitly, documenting personal and family history of sudden death, exertional syncope, prior concussions, sickle cell trait, and heat illness.
Returning an athlete after ACL reconstruction, concussion, or hamstring strain based on elapsed time rather than objective criteria.
Timelines are easier to recall than criterion batteries, and vignettes supply a tempting date that invites a time-based answer.
What to do instead
Use criterion-based return to play: at least 90% limb symmetry on strength and hop testing for ACL, symptom-free graduated exertion for concussion, and pain-free maximal sprinting for hamstring strain.
Applying adult return-to-play and exercise-prescription rules unchanged to youth, masters, pregnant, or wheelchair athletes.
Adult protocols dominate training, and special populations appear in only a subset of vignettes, so modifying factors are not retrieved.
What to do instead
For each special population, name the one or two modifying factors: growth-plate and concussion susceptibility in youth, supine-exercise and contact limits in pregnancy, and autonomic dysreflexia and pressure injury in wheelchair athletes.
In exertional heat stroke, delaying cold-water immersion to transport or give IV fluids; in suspected cervical spine injury, removing the helmet without shoulder pads or log-rolling without indication.
Emergency algorithms compete for attention, and candidates prioritize transport and IV access over immediate cooling or misremember equipment-removal rules.
What to do instead
State 'cool first, transport second' and target immersion within minutes; for equipment removal, remove both helmet and shoulder pads together or neither, keeping the spine neutral.
Injecting a joint with overlying cellulitis, suspected septic arthritis, or coagulopathy, or aspirating and then injecting without sending fluid when infection is possible.
Procedure questions emphasize landmark and technique, so contraindications and fluid handling get skipped.
What to do instead
Before any injection, state the contraindications (local infection, bacteremia, septic joint, coagulopathy, allergy); when infection is in the differential, aspirate and send cell count and culture before corticosteroid.
Calling a hypoechoic tendon region a tear without correcting for anisotropy, comparing with the contralateral side, or using dynamic imaging.
Anisotropy mimics pathology, static images are easier to test, and candidates forget transducer angle and dynamic assessment.
What to do instead
Use a systematic protocol: optimize gain and depth, keep the beam perpendicular, scan in two planes, compare sides, and use dynamic maneuvers; reserve 'tear' for discrete fiber discontinuity.
