1. Meniscus Injuries
Jasmine Hawkins

2. Anatomy of the Knee Largest and most complex
Vulnerable to a variety of injuries
Weight bearing joint
Stabilizes the leg
Most easily injured in sports
Made up of:
Bones
Cartilage
Ligaments
Tendons

3. Meniscus Injury Causes
Trauma
Sudden/Forceful twisting
Quick changes in position
Repeated motions
Sudden stopping
Pivoting
Direct contact
Abnormal motion

4. Causes continued… Synovitis Inflammation of the synovial lining
Old age
Cartilage weakens and wears thin overtime
MEANING: torn tissue is more prone to tears!

5. Meniscus Injury Signs/Symptoms
Mechanism of injury
Twisting
Squatting
Changes in position
Dependent on:
Size of the tear
Location of the tear
If another knee injury is associated

6. Signs/Symptoms continued…
Mechanism complaints
Locking
Catching
Pinching
Giving sensation
Swelling
Pain
Lack of range of motion
Effusion
Accumulation of excess fluid

7. Meniscus Injury Care/Treatment
Physical Therapy
Surgery

8. Care/Treatment continued…
Corticosteroid injections
Maintaining knee fitness
Strength
Flexibility
Proprioception
Care/Treatment continued…
Wearing Appropriate Shoes

9. Meniscus Injury Statistics
Menisci don’t have a strong arterial blood supply = do not heal well after being injured
Patients older than 65 y.o, the rate of degenerative tears is 60%
Meniscus Injury Statistics
Structural differences in the collagen fibrils contribute to the ability of the menisci to be fully functional after repair
Joint line tenderness indicates 77-86% of patients meniscus tears

10. Statistic continued… Medial menisci vs. Lateral menisci
Medial is “C”-shaped
Lateral is closer to the letter “O”
Three zones within the meniscus:
Red-red zone
Red-white zone
White-white zone

11. ACL Injuries
By: Jeremy Bender

12. Anatomy of the Knee ACL is one the largest ligaments in the body
Creates an ‘x’-shape with the PCL

13. Causes of ACL Injuries Contact sports Low velocity Non-contact
Quick stopping movement

14. Signs of ACL Injuries Feeling or hearing a “pop”
Knee swelling within 6 hours
Development of a large hemarthrosis

15. More Signs of ACL Injuries
Inability to continue activity
Pain
when weight is put on injured knee
along joint line

16. Care of ACL Injuries ACL Reconstruction primary repair
extra-articular repair
intra-articular repair

17. More Care of ACL Injuries
Non-surgical
Bracing/Physical Therapy
Strengthening
Quads
Hamstrings
ROM exercises

18. Statistics About ACL Injuries
Surgery + Rehabilitation for an ACL tear = $17,000-$25,000 per patient
60,000-75,000 ACL reconstructions are performed annually in the U.S.
100,000 overall
Success rates for ACL reconstruction: 75-95%
Failure rate: ~ 8%
50% of patients have meniscal tears

19. More Statistics of ACL Injuries
More females injury their ACL’s than males
Military training and handball have the highest ratios of any sport
70% of ACL tears are non-contact
1 case in 3,500 people result in…
95,000 new ACL ruptures per year
200,000 ACL injuries per year
