Week 10 - Knee condition Flashcards
List specific condition (3 acute, 5 insidious) of the knee (8)
- Ligament tears/ruptures
- meniscal injury
- Patellar dislocation
- OA
- ITBFS
- PFPS
- Fat pad irritation/impingement
- Tendinopathy
List the contributing factors (local and remote) to poor patella tracking (5)
- Patella position
- Soft tissues (retinaculum, laxity)
- Neuromuscular control of Vasti (Weakness, Timing of VMO)
- Tightness of lateral complex (ITB, TFL)
- Lower limb alignment (IR, knee valgus, Tibila rotation, subtler pronation)
What factors increase the Q angle (normally 17 deg for females and 14 deg for males)? (4)
- Genu algum
- Femoral internal rotation
- External tibial rotation
- Tight lateral retinaculum
What risk factors associated with knee varus thrust?
Medial knee OA progression
What is a sign of poor dynamic knee control?
Knee medial to foot (relative to 2nd MT)
What is a risk associated with poor dynamic knee alignment?
increased risk of ACL injury
What are the functions of the meniscus? (3)
- Increases congruence
- Increases articular surface area
- Reduces WB forces
What is a common MOI of the meniscus?
Twisting & weight-bearing
What are clinical features associated with diagnosing meniscal injury? (3)
- Joint tenderness
- McMurray’s test
- Joint effusion (brush swipe test)
What type of meniscal tears associated with clicking & locking? (3)
- Bucket handle
- Parrot’s beak tear
- Horizontal flap tear
When should you conservatively Mx meniscal injury? (3)
- Pain on McMurrays test only at full flexion. (if later, “clunk” or locking = surgical)
- Trial where injury is minimal/peripheral tear
- Able to weight-bear
