OCS: Orthopaedic Clinical Specialist Certification Exam Practice Test
The Orthopaedic Clinical Specialist (OCS) certification, administered by the American Board of Physical Therapy Specialties (ABPTS), is the premier credential for physical therapists demonstrating advanced clinical expertise in orthopaedic practice. This board-certified specialty represents the highest standard of knowledge, skill, and experience in the evaluation, diagnosis, and treatment of musculoskeletal disorders. Earning the OCS signifies a commitment to evidence-based practice, clinical reasoning, and superior patient outcomes across diverse orthopaedic populations. The certification validates a therapist's ability to manage complex cases, integrate current research into clinical decision-making, and serve as a leader within the orthopaedic rehabilitation community. It is a rigorous, peer-reviewed process that distinguishes certified clinicians as experts in their field, enhancing both professional credibility and the quality of patient care. Holders of the OCS credential are recognized for their dedication to lifelong learning and specialization beyond entry-level competence.

A 71-year-old patient is 6 weeks post-uncomplicated total knee arthroplasty. He has 0-115° active ROM, 4+/5 quadriceps strength, walks independently with a cane outdoors, and reports pain 2/10 with activity. He asks about returning to activities. Which counseling is most evidence-based regarding return to activities post-TKA?
A 60-year-old man reports 3 months of buttock and posterior-thigh pain extending to the popliteal fossa, but not below the knee. Pain is worse with prolonged sitting and standing from chairs. He has full lumbar flexion, no centralization, negative SLR bilaterally, but reduced hip internal rotation 5° (vs 30° contralateral) and a positive scour with reproduction of his familiar pain. Imaging shows mild degenerative changes at L4-L5 and Kellgren-Lawrence grade 2 hip OA. Which clinical reasoning best assigns the primary pain generator and guides initial intervention?
A 43-year-old recreational hiker reports 3 months of medial knee pain with mechanical catching during squatting and a single episode of locking. Examination reveals medial joint-line tenderness, positive McMurray with painful click, and a positive Thessaly test at 20°. To rule in a medial meniscal tear, which test in this stem has the BEST diagnostic accuracy when positive?
A 19-year-old female collegiate soccer player is 6 months post-op ACL reconstruction with bone-patellar-tendon-bone autograft. She reports knee feels "ready" and has 95% quadriceps Limb Symmetry Index (LSI) on isokinetic testing, hop-test LSI of 92%, IKDC score of 89, and full ROM. She has not yet returned to sport. Per the 2020 BJSM Aspetar consensus and Grindem's prognostic data, what is the MOST important threshold she must meet before unrestricted return-to-sport, and what is the prognostic implication if released early?
A 60-year-old patient with knee OA has failed exercise and weight loss interventions. The orthopedic physician offers three injection options: corticosteroid, hyaluronic acid (HA / viscosupplementation), and platelet-rich plasma (PRP). Per current best evidence (2019 OARSI, 2020 ACR/AF, recent meta-analyses), which statement most accurately characterizes the comparative evidence?
