NORMAL KNEE MOTION KNEE FLEXION-EXTENSION takes place between the bottom of the femur and the top of the menisci. TWISTING MOTION takes place between the bottom of the menisci and the tibia.
Slide 31-

MENISCUS OF THE KNEE Purpose: Equalize weight distribution across the knee joint. Shock absorption.
Slide 32-

Coronary Ligament Medial is tighter than the lateral. Thus, there is less mobility medially.
Slide 33-

MENISCAL INJURY Medial Meniscus: excessive external rotation of the tibia. Lateral Meniscus: excessive flexion of the knee.

MECHANISMS OF INJURY VALGUS VARUS HYPEREXTENSION HYPERFLEXION INTERNAL ROTATION EXTERNAL ROTATION

Slide 57-

Mechanisms of Injury MCL Valgus of Knee ACL Valgus after MCL Extension with tibia in internal rotation. Hyperextension.
Slide 58-

PCL Valgus after MCL and ACL. Varus after LCL,ACL Hyperflexion with tibial internal rotation. Blunt trauma to tibial tuberosity.
Slide 59-

FCL Varus of knee. M.M. External rotation of the tibia. Valgus to knee. L.M. Hyperflexion of the knee.

SIGNS AND SYMPTOMS OF LIGAMENT INJURY (Not all symptoms have to be present to indicate injury) Immediate pain ++++ Feeling of tearing. Hearing unusual noises. …. 2.
Slide 61-

.. 2 Signs and Symptoms Feeling of ‘giving way’. Loss of function of the joint Be cautious of the ‘painful’ and then ‘not very painful’ knee.
Slide 62-

REMOVAL FROM FIELD (Non-weight Bearing) Feeling of a tearing or popping in the knee. If pain, no pain.
Slide 63-

REMOVAL FROM FIELD (Non-weight bearing) If complaining of ‘not feeling right’ or feeling ‘funny’
Slide 64-

REMOVAL FROM FIELD Weight bearing Minor pain with full R.O.M. Stand. Pain? Slowly walk off field with support.
Slide 65-

Return to play only after the athlete has been evaluated by a physician.

PATELLO-FEMORAL PAIN SYNDROME Causes: . Excessive Q angle. . Excessive pronation. . Weak plantar flexors/inv. . Weak V. Medialis/Tight Ham
Slide 70-

Q Q ANGLE (Quadriceps) Two lines; ASIS to MPP; the other from TT to MPP. Angle of intersection called ‘Q angle’.
Slide 71-

The greater the Q angle, the greater the tendency to move the patella laterally against the lateral femoral condyle. A large Q angle plus strong quad contraction can dislocate pat.
Slide 72-

Slide 73-

Equal pressure distribution across the back of the patellae ensures proper nutrition by inbibition.
Slide 74-

Medial aspect of Patellofemoral Joint has hypopressure. Lateral aspect has hyperpressure. + - - +

Slide 76-

Signs and Symptoms of Patello-femoral Pain Syn. Painful crepitus of the knee. Locking, catching of knee. Swelling. Loss of strength. Activity worsens symptoms.
Slide 77-

SUGGESTED TREATMENTS Strengthen Vastus Medialis. Reduce Pronation. Stretch Hamstrings, ITB, and Quads. Modify activities.
Slide 78-

Slide 79-

The greater the Q angle, the greater the tendency to move the patella laterally against the lateral femoral condyle. A large Q angle plus strong quad contraction can dislocate pat.
Slide 80-

“ My knee came apart and went back together again”. For example, “I was running forward, planted on my right foot, cut to my left and attempted to push off with my right”.
Slide 81-

Lateral Medial SUBLUXED OR DISLOCATED PATELLA
Slide 82-

DISLOCATED PATELLA
Slide 83-

If the patella is dislocated, slightly flex the hip and slowly extend the knee. Usually the patella relocates. If it does not, do not force the patella medial. There may be some associated fractures (back of the patella, lateral femoral condyle). MEDICAL

Inform parents. Stop irritating activity. Icing the tibial tubercle. Stove-pipe casts are some- times applied to ensure rest. Return if asymptomatic.
