9. Knee Evaluation (History)
Determining the mechanism of injury is critical
History- Current Injury
Past history
Mechanism- what position was your body in?
Did the knee collapse?
Did you hear or feel anything?
Could you move your knee immediately after injury or was it locked?
Did swelling occur?
Where was the pain
History - Recurrent or Chronic Injury
What is your major complaint?
When did you first notice the condition?
Is there recurrent swelling?
Does the knee lock or catch?
Is there severe pain?
Grinding or grating?
Does it ever feel like giving way?
What does it feel like when ascending and descending stairs?
What past treatment have you undergone?

10. Knee Evaluation (Observation)
Walking, half squatting, going up and down stairs
Swelling, ecchymosis,
Leg alignment
Genu valgum and genu varum
Hyperextension and hyperflexion
Patella alta and baja
Patella rotated inward or outward
May cause a combination of problems

11. Knee Evaluation (Observation)
Knee Symmetry or Asymmetry
Do the knees look symmetrical? Is there obvious swelling? Atrophy?
Leg Length Discrepancy
Anatomical or functional
Anatomical differences can potentially cause problems in all weight bearing joints
Functional differences can be caused by pelvic rotations or mal-alignment of the spine

12. Knee Evaluation (Palpation)
Palpation – Bony
Medial tibial plateau
Medial femoral condyle
Adductor tubercle
Gerdy’s tubercle
Lateral tibial plateau
Lateral femoral condyle
Lateral epicondyle
Head of fibula
Tibial tuberosity
Superior and inferior patella borders (base and apex)
Around the periphery of the knee relaxed, in full flexion and extension

13. Knee Evaluation (Palpation)
Palpation - Soft Tissue
Vastus medialis
Vastus lateralis
Vastus intermedius
Rectus femoris
Quadriceps and patellar tendon
Sartorius
Medial patellar plica
Anterior joint capsule
Iliotibial Band
Arcuate complex
Medial and lateral collateral ligaments
Pes anserine
Medial/lateral joint capsule
Semitendinosus
Semimembranosus
Gastrocnemius
Popliteus
Biceps Femoris

14. Knee Evaluation (Special Tests)
Active / Passive Range of Motion
Flexion – 0o to 135o
Extension – 130o to 0o
Manual Muscle Testing
Five Point grading system
5 = Complete ROM against gravity, with full resistance
4 = Complete ROM against gravity, with some resistance
3 = Complete ROM against gravity, with no resistance
2 = Complete ROM, with gravity omitted
1 = Some muscle contractility with no joint motion
0 = No muscle contractility
Knee Flexion / Extension
Hip Flexion / Extension / Internal Rotation / External Rotation
Dorsiflexion / Plantar Flexion

15. Knee Evaluation (Special Tests)
Joint Instability
Medial Collateral Ligament Instability

16. Knee Evaluation (Special Tests)
Joint Instability
Lateral Collateral Ligament Instability

17. Knee Evaluation (Special Tests)
Joint Instability
Anterior Cruciate Ligament (Lachman’s Test)
Will not force knee into painful flexion immediately after injury
Reduces hamstring involvement
At 30 degrees of flexion an attempt is made to translate the tibia anteriorly on the femur
A positive test indicates damage to the ACL

18. Knee Evaluation (Special Tests)
Joint Instability
Anterior Cruciate Ligament (Ant. Drawer)
Drawer test at 90 degrees of flexion
Tibia sliding forward from under the femur is considered a positive sign (ACL)
Should be performed w/ knee internally and externally to test integrity of joint capsule

19. Knee Evaluation (Special Test)
Other ACL Stability Tests
Pivot Shift Test
Used to determine anterolateral rotary instability
Position starts w/ knee extended and leg internally rotated
The thigh and knee are then flexed w/ a valgus stress applied to the knee
Reduction of the tibial plateau (producing a clunk) is a positive sign
Jerk Test
Reverses direction of the pivot shift
Moves from position of flexion to extension
W/out and ACL the tibia will sublux at 20 degrees of flexion

20. Posterior Cruciate Ligament Stability
Joint Stability Tests
Posterior Cruciate Ligament Stability
Posterior Sag Test (Godfrey’s test)
Athlete is supine w/ both knees flexed to 90 degrees
Lateral observation is required to determine extent of posterior sag while comparing bilaterally

21. Knee Evaluation (Special Tests)
Other Posterior Cruciate Ligament Tests
Posterior Drawer Test
Knee is flexed at 90 degrees and a posterior force is applied to determine translation posteriorly
Positive sign indicates a PCL deficient knee

22. Knee Evaluation (Special Tests)
Meniscal Pathology
McMurray’s Meniscal Test
Used to determine displaceable meniscal tear
Leg is moved into flexion and extension while knee is internally and externally rotated in conjunction w/ valgus and varus stressing
A positive test is found w/ clicking and popping response
Medial Meniscus Testing

23. Knee Evaluation (Special Tests)
McMurray Test Continued
Lateral Meniscus Test

24. Knee Evaluation (Special Tests)
Meniscal Pathology
Apley’s Compression Test
Hard downward pressure is applied w/ rotation
Pain indicates a meniscal injury
Apley’s Distraction Test
Traction is applied w/ rotation
Pain will occur if there is damage to the capsule or ligaments
No pain will occur if it is meniscal

25. Knee Evaluation Palpation of the Patella
Must palpate around and under patella to determine points of pain
Patella Grinding, Compression and Apprehension Tests
A series of glides and compressions are performed w/ the patella to determine integrity of patellar cartilage

26. Knee Rehabilitation Bag of Tricks Range of Motion
Joint Mobilization, Soft-Tissue Mobilization
Neuromuscular Control
Proprioceptive Neuromuscular Facilitation
Postural Stability
Core Stability training
Muscular Strength, Endurance, and Power
Plyometrics, Open KC, Closed KC, Isokinetics, Aquatics
Cardiovascular Endurance

27. Knee Rehabilitation Three simple keys Range of Motion Strength
Needed to increase motion and return to function as quickly as prudent and possible
Strength
Needed to deter further problems or protect the area of injury from further injury
Functionality
Needed to return the student-athlete or patient to normal daily activities within reason.

28. Knee Rehabilitation Range of Motion Theory’s
Passive ROM is the key to early ROM
Active ROM starts and progresses as treatments continue
“Normal” Knee ROM
Knee Flexion = 0o to 130o+
Knee Extension = 130o+ to 0o+

29. Knee Rehabilitation Passive Range of Motion Exercises
Flexion Exercises
Wall Hangs (assisting device is gravity)
Towel Slides (assisting device is arms)
Stationary Bike (assisting device is other leg)
Extension Exercises
Table Hangs

More stable for the knee joint
Exercise include:
Mini-Squats (or with Swiss ball)
Wall Slides
Lunges (as ROM permits)
