Familiarize you with common features of
injuries
Reinforce what you already know about
diagnosis and treatment
Help decision making as far as treatment or
referral
Reviewing pertinent anatomy, History and
Physical findings
Review differences in adult and pediatric
injury patterns
Give some PEARLS
Bones more pertinent in pediatric group
Tendons – Patellar and Quadriceps
Cartilage – articular and meniscal
Ligaments – ACL, PCL, Medial and lLateral
Collateral
Cartilage is like a rock in your shoe pain and
swelling the more you do the more it hurts
Ligament injuries are like walking on ice
DOES IT HURT AND GIVE OUT OR GIVEOUT
AND HURT?
Often minor trauma in adults due to
degeneration, sometimes feel a pop
Feel a click plus or minus effusion (popliteal)
Joint line tenderness pain with rotation
(McMurray, Appley, etc)
Pain and swelling with activity, low grade
Usually surgical or live with it
Meniscus relatively inert and poor healing
potential
Outpatient procedure, arthroscopic, 2 to 4
weeks return to many sports if motivated
Not a surgical emergency, difficult to play
through
“Repair” usually means taking out torn
portion
Only 10% repairable (bucket and vertical
tears in outer 1/3)
NFL meniscal injuries more career ending
than ACL
Most common in sports particularly with
acceleration/deceleration
Not always a violent injury many noncontact
Classic is feel a pop followed by intense
swelling within 6 hours (hemarthrosis)
Not a surgical emergency Surgery often
delayed 3 or more weeks (reconstruction)
May have effusion may not some walk in
comfortable
Lachman’s test is most classic and STILL
most useful
Often missed on MRI (femoral detachment
difficult to pick up)
Not always surgical initial RICE and ROM
PT for quad hamstring strengthening
Brace treatment
Coping and sport modification
Surgery
Reconstruction with multiple graft choices
Who gets it? – under 40, women, buckling
with daily activity, competitive level 1 sports
Outpatient surgery mostly arthroscopic
return to full sport variable but 6months to
one year
More rare usually in the realm of orthopedist
Not a “Pulled muscle”
Many are not surgical but require detailed
diagnosis (combined injuries)
Not emergency but protection with crutches
and immobilizer needed
Bones now important
Physeal injuries common (weaker than
ligaments and cartilage)
Different age leads to different fractures ie
tibial eminence 12yrs tibial tubercal 14yrs
ACL eqivalent in younger age
Same mechanism of injury
May require surgery usually requires referral
Typically occur during adolescence
3 types depending on severity
Only most severe (type 3) require surgery but
all require referral
Common in younger kids
Represents an avulsion of inferior patellar
cartilage from bone
Analogous to patellar tendon rupture in
adults
Can be difficult to diagnose (pain, fear etc)
Usually occur during adolescence
Three types depending on severity
Only type 3 requires surgery but all require
referral for treatment
History and physical still the key as imaging is
confirmatory.
Most injuries not a “pulled muscle”
Relax most are not surgical emergencies
Pediatric injuries tend to be physeal and more
emergent
