Orthopedic Certification Test 70 Questions with Verified
Answers,100% CORRECT
Cartilage is made of - Correct answer-collagen and protein
Joint Cartilage is made of - Correct answer-extracellular matrix and chondrocytes
Extracellular matrix contains primarily - Correct answer-type 2, 4, and 6 collagens as well as aggrecan
proteoglycans
Type 2 collagen is responsible for - Correct answer-protecting the ends of bone within a joint
Aggrecan proteoglycan is mainly responsible for - Correct answer-retaining water molecules, allowing
resistance to affects of strenuous use of the joint
Chondrocytes within joint cartilage is responsible for - Correct answer-the strength and resistance to
loading
What is the pathophysiology of osteoarthritis? - Correct answer-when cartilage becomes damaged it
starts to lose elasticity, making it more susceptible to injury. With increasing stress and wear the bone
starts to become affected causing thickening of bone and formation of bone spurs and osteophytes.
Abnormal bone formations can break loose with cartilage fragments and float within joint space. Debris
cause synovium to mount and inflammatory response to break down cartilaginous debris.

Answers,100% CORRECT
What does the inflammatory response during degeneration of cartilage increase? - Correct answer-the
breakdown of remaining healthy cartilage, leading to further degeneration
Osteoarthritis symptoms: - Correct answer-pain that is exacerbated with activity and better with rest
(early dz), stiffness, swelling, pain and stiffness worse in the morning (no more than 30 min), pain worse
with prolong inactivity or weather changes
Hip osteoarthritis symptoms: - Correct answer-pain in low back and groin, limping and knee pain from
compensation
Knee osteoarthritis symptoms: - Correct answer-locking, cracking, grinding, "give out" feeling, increasing
pain with ascending and descending stairs
Finger osteoarthritis symptoms: - Correct answer-swelling, nodules, stiffness, difficulty gripping
What are causes of secondary osteoarthritis? - Correct answer-joint injury (fracture or sprain), chronic
stress, joint instability, nervous system disorders (ex. charcot neuropathy), blood and endocrine
disorders (diabetes, gout, thyroid disorders, osteoarthritis, growth hormone disorders), medications
(oral steroids, meds for gout), inflammation (RA causing secondary osteoarthritis)
What are diagnostic tests for osteoarthritis? - Correct answer-blood work to eliminate other disorders
such as RA and to establish base line and possible secondary osteoarthritis diseases, X-rays, possible
MRI, evaluation of synovial fluid
Mild pain is generally rated as this number out of 10 - Correct answer-0-3
Moderate pain is generally rated as this number out of 10 - Correct answer-4-6
Severe pain is generally rates as this number out of ten - Correct answer-7-10
Salter-Harris pediatric fracture classifications:
This Grade of fracture is straight across the bone? - Correct answer-Grade I
