PURPOSE
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
![Page 4: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/4.jpg)
ACCOMPLISH GOAL Reviewing pertinent anatomy,
History and Physical findings
Review differences in adult and pediatric injury patterns
Give some PEARLS

ANATOMY OF KNEE Bones more pertinent in pediatric
group
Tendons – Patellar and Quadriceps
Cartilage – articular and meniscal
Ligaments – ACL, PCL, Medial and lLateral Collateral
![Page 8: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/8.jpg)
LIGAMENT VS CARTILAGE 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?
![Page 9: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/9.jpg)
MENSICUS HISTORY AND EXAM 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
![Page 10: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/10.jpg)
MENISCUS INJURY TREATMENT 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
![Page 11: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/11.jpg)
MENISCAL SURGERY “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
![Page 12: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/12.jpg)

ANTERIOR CRUCIATE INJURIES 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)

ACL TEAR DIAGNOSIS 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)
![Page 17: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/17.jpg)

ACL TREATMENT Not always surgical initial RICE and
ROM
PT for quad hamstring strengthening
Brace treatment
Coping and sport modification
Surgery
![Page 19: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/19.jpg)
ACL 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
![Page 20: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/20.jpg)
PCL & COLLATERAL LIGAMENT 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
![Page 21: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/21.jpg)
PEDIATRIC KNEE INJURIES Bones now important
Physeal injuries common (weaker than ligaments and cartilage)
Different age leads to different fractures ie tibial eminence 12yrs tibial tubercal 14yrs
![Page 22: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/22.jpg)
TIBIAL EMINENCE FRACTURE ACL eqivalent in younger age
Same mechanism of injury
May require surgery usually requires referral
![Page 23: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/23.jpg)

TIBIAL TUBERCULE FRACTURES Typically occur during adolescence
3 types depending on severity
Only most severe (type 3) require surgery but all require referral
![Page 26: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/26.jpg)
PATELLAR SLEEVE FRACTURE 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)
![Page 27: COMMON KNEE INURIES IN SPORTS MEDICINE](https://reader036.vdocuments.mx/reader036/viewer/2022062501/5681652e550346895dd7b2e0/html5/thumbnails/27.jpg)

TIBIAL TUBERCULE FRACTURES Usually occur during adolescence
Three types depending on severity
Only type 3 requires surgery but all require referral for treatment

CONCLUSION 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
