Knee Pathologies
Cards in this deck (19)
- 1Function of Menisci (5)*Attached to tibial plateau
*Protects articular cartilage
*Shock absorbing
*Provide stability to knee
*Allow gliding movement through lubrication by synovial fluid - 2Which ligament is most prone to injury?Anterior cruciate ligament
- 3Function of the anterior cruciate ligament? (2)*Supports the knee during maximum flexion.
*It doesn't allow for forward motion over the tibia. - 4Genu VarumFrontal plane malalignment of the lower limb where the thigh is in valgus, and the lower leg is in varus, when the patient stands in relaxed stance with the feet together
- 5Genu varum
- 6Normal Development - genu varum is? Should resolve by? When is it considered abnormal?is normal in new born infant
•Should resolve by the age of 2
•Considered ‘abnormal’ at age of 4 - 7Genu Varum - the foot adopts which position in relation to the ground? Compensation depends on?*Foot adopts inverted position in relation to the ground (therefore acts as a rearfoot varus)
*Compensation depends on STJ pronation available - 8What is the knee ADDuction moment?Knee ADDuction moment may be described as the turning effect of the ground reaction force acting on the foot as it passes medial to the centre of the knee joint
- 9Genu Valgum is a?Genu valgum is a frontal plane malalignment of the lower limb, where the thigh is in varus and the lower leg is in valgus when the patient is in relaxed stance with the feet together
- 10Genu Valgum image?
- 11Normal development? May be present from? Reduces between? May develop again between the ages of?3-5 years
6-8 years
May develop again between ages 12-14 years which usually spontaneously corrects - 12Genu valgum compensation?May appear pronated but then supinates during propulsion.
- 13Management (8)*Referral – if severe with suspected underlying disease (orthopaedic surgery)
*Determine cause
*Even mild deformity in active/athletic patients may cause significant problems
*Functional foot orthoses
*Medial and lateral wedges
*Treat secondary lesions: - debridement, P+S
*Physical therapies for chronic knee pain (referral)
*Rest - 14Q Angle
- 15The normal Q angles are ?14 degrees for males
17 degrees for females (wider pelvis) - 16Genu Recurvatum is associated with? It is the compensation mechanism for? The knees may not? There is? It is more common in?oHyperextension of the knee joint (sagittal plane)
* joint laxity
* ankle equinus
* hyperextend during gait
*STJ pronation
*Knee pain
*More common in females - 17Basic strain Medial collateral ligament injury grade I?A hint of laxity
- 18Medial collateral ligament injury grade II?medial joint line opening < 1cm
- 19Medial collateral ligament injury grade III?medial joint line opening > 1cm
