The Knee pathologies Flashcards
What is MOI for MCL injury?
Contact: direct valgus to knee
Noncontact: observed with decelerating, cutting and pivoting motions
What is the body chart/symptoms for MCL?
Pain on medial side instability on stepping and twisting swelling/bruising A tearing sound/sensation A Valgus force movement
What is MOI for LCL injury?
Usually as a result of a varus force across knee
Direct blow on medial knee joint line
Indirect injury mechanism e.g. hyperextension stress causing a varus force
What is the body chart/symptoms for LCL?
Pain on lateral side instability on stepping and twisting swelling/bruising A tearing sound/sensation A Varus force movement
Management of MCL/LCL?
ACUTE= POLICE
Offloading of the knee as required with crutches
Quadriceps activation exercises- straightening leg on plinth down on towel
SUB-ACUTE:
Close chain strength work- all muscles
Full AROM of knee
LONG-TERM-
Proprioception work- foam block
Whole kinetic chain exercises
Aerobic conditioning
MOI and Age for Meniscus injuries?
Young adults
Medial meniscus- more common as its less mobile
Trauma- sudden rotation in weight bearing position
Degenerative- Repeated kneeling/squatting (e.g. labourers)
Body chart/ symptoms for Meniscus injuries?
Pain is commonly intermittent
Localised to joint line
Mechanical complaints; locking/pinching, clicking and sensation of giving way
MOI for ACL injury?
Non-contact: sudden deceleration prior to change of direction/landing motion
Contact: result of valgus collapse of the knee
Symptoms of ACL injury?
Popping sound, increase laxity, swelling/effusion. limitations in movements/instability
MOI for PCL injury?
Following anterior blow to tibia with knee in flexion
Symptoms of PCL injury?
Sharp/dull pain around the back of the knee
Swelling/ effusion
Stiffness
Articular cartilage/Osteoarthritis MOI?
Traumatic/Overuse
Possible excessive, rotational force for acute injury
Symptoms of Articular cartilage?
Swelling
Vague pain
Locking/catching- lose body
Stiffness and reduced ROM
Possible causes of Patella femoral pain syndrome?
Patella has different orientation- may glide more to one side of femur, causing overuse/overpressure
Muscle weakness of quadriceps and glutes- muscle imbalance effecting tracking of patella
Symptoms of Patella femoral pain syndrome?
Pain localised in patellofemoral joint
Anterior knee pain
Aggravating factors for Patella femoral pain syndrome?
squatting, kneeling prolonged sitting, running, stair- activities which increase compressive force of patellofemoral
Age/MOI for Patellar tendinopathy?
Young athletes- repetitive loading of the patella tendon
Overuse
Symptoms of Patellar tendinopathy?
Anterior knee pain- localised to inferior pole of patella
Aggravating factors of Patellar tendinopathy?
Aggravated by loading and knee extension
pain rarely experienced in the resting state
