Knee Stability and Movement Coordination Impairments Flashcards
What motions does the MCL limit?
Valgus and ER
What motions does the LCL limit?
Varus and ER
What motions does the ACL limit?
Anterior Translation and IR
What motions does the PCL limit?
Posterior Translation and IR
With this patient population, what may you hear in the Subjective Hx?
- Sx onset is linked with trauma
- “Pop” heard or felt at time of injury
- hemarthrosis with 0 - 12 hrs post injury
- Describes sense of knee instability (“Gives out”)
- Stiffness and pain
With these patients, what is the MOI?
Deceleration, cutting or valgus motion
With these patients, what are some Clinical Findings during the Examination?
- Palpation for Condition: Effusion
- AROM: Decreased knee flexion/extension
- MMT: Decreased quads/hamstrings strength
- Proprioception: Single balance impaired
- Movement Analysis: Cpmpensatory Strategies
With these patients, what may you find during Ligament Integrity Test?
- Excessive tibiofemoral laxity with cruciate/collateral ligament integrity tests
What test(s) are done to test the integrity of the ACL?
- Anterior Drawer
- Lachman Test (Best, however hardest)
- Lateral Pivot Shift Test
What test(s) are done to test the integrity of the MCL?
Valgus stress test
What test(s) are done to test the integrity of the LCL?
Varus stress test
What test(s) are done to test the integrity of the PCL?
- Posterior Sag Test
- Posterior Drawer Test
With these patients, during the examination, what Impairment Measures can be done?
- Star Excusion Balance Test
- Single Leg Hop for Distance
- Crossover Hop Test for Distance
- Triple Hop Test for Distance
- 6 Meter Hop for Time
Not in Acute or Subacute Stage of Healing
What is the prognosis for these patients?
- Dependent on type and severity of ligamentous injury
- Joint mobility
- LE strength
- Movement co-ordinations
- Psychosocial status
- Surgical intervention
- Goals and level of function
With Interventions, what is done with Early Rehabilitation Strategies?
- Edema Management - Cryotherapy
- Progressive Early ROM
- Progressive Early Weight Bearing
- Neuromuscular Electrical Stimulation
- Bracing Support
- Strengthening Quads, Posterior Lower Kinetic Chain
With Interventions, what is done with Early-Late Rehabilitation Strategies?
Therapeutic Exercise
- Optimal ROM, strength, flexibility
- Addressing impairments with foot/ankle, hip and trunk regions
Neuromuscular Re-Education
- Field/Court sports performance
Education/Counselling Strategies
- Activity modification, return to sport readiness, and whether or not surgery is required
