Ligamentous Injuries
Can be applied to most ligament injuries throughout the extremities.
Grade 1 – Pain No laxity
Grade 2 – pain with laxity/deformity – with End feel* .
Grade 3 – Pain – severe laxity/deformity – No end feel*
* Knee/ankle
ACjt/SCjt Ligamentous injuries
Common Mechanisms of injury:
FOOSH
Direct blow
Grade according to pain and amount of disruption
Treatment:
Broad arm sling for both
Follow up if Grade 2 or above
Grade 3 May need surgical intervention
Ligametous shoulder injuries
True dislocation of the shoulder joint will have caused significant ligamentous injury – look out for Bankhart lesions
Rotator cuff injury more of note
Efficient history taking with appropriate examination will give info as the integrity of the cuff
Shoulder Assessment
Observation (Look): Deformity Muscle wasting Swelling Structure alignment Palpation (Feel): Heat Pulses Sensation Palpation for site of lesion
Move
Active range of motion. Flexion/Extension/Abd/Add/Medial/lateral
Passive range of motion. Flexion/Extension/Abd/Add/Medial/lateral
Resisted muscle testing
Special tests – impingement tests / Cuff integrity tests
Check joint above and below
Broad Arm Sling
Knee Anatomy - Anterior
Mechanisms of Injury –
Meniscal Lesions
Common in activities involving forced rotation on a weight-bearing leg.
Can be slow onset of effusion.
Localised ant/med knee jt pain - commonly.
If age>50yrs then consider degenerative meniscus if no history of trauma.
Mechanisms of Injury - ACL
Can be produced by:
Pure Hyperextension
Combination of valgus force and external rotation of the tibia relative to the femur
Contact sports
Rapid onset Haemarhtrosis
Feeling of instability
Inability to bear weight
Mechanisms of Injury - MCL
Can be produced by:
Valgus Force
With or without rotation
Proximal origin most effected
Can be combination injury due to multiple attachments
Mechanisms of Injury - LCL
Can be produced by:
Varus forces
Much less common than MCL injuries
Quadriceps Tendon Rupture
History
Significant injury
Palpate on each assessment to confirm integrity
Straight leg raise – be suspicious if unable
Knee Assessment
Observation (look): Deformity Muscle wasting Swelling Structure alignment Palpation: Heat Swelling – sweep tests Pulses Palpation for site of lesion OTTAWA RULE
Active range of motion. Flex/Ext
Passive range of motion. Flex/Ext/MR/LR
Resisted muscle testing. Flex/Ext/MR/LR
Special tests – Ligamentous tests
Straight leg raise.
Patella. Position. Tenderness
Palpation for site of lesion
Gait Analysis
Special Tests
Valgus MCL
Varus LCL
PCL Posterior Sag, Gravity
test, Pencil test
ACL Anterior Drawer,
Lachmans
Menisci McMurrays
PCL INJURIES
The Pencil Test
Anterior Drawer
Lachman’s Test
Medial Stress test
Lateral Stress Test
OTTAWA KNEE RULE
For knee injuries – not insidious onset
Age 55 years or older
Tenderness at head of fibula
Isolated tenderness of patella
Inability to flex knee to 90 degrees
Inability to walk four weight-bearing steps at once after the injury and in the emergency department
Ligamentous ankle injury
Mechanism
Commonly combination of inversion/plantarflexion/ medial rotation
Eversion less common – be concerned!
Ability to weight bear immediately
Begin assessment at the knee
OTTAWA ANKLE RULE
Foot
Tubigrip
To apply or not?
Not much evidence that use will reduce patients pain, reduce swelling or aid recovery
?reduces proprioceptive input and recovery of muscle activity
Great placebo though!
