PF disorders part 2 Flashcards

1
Q

summarize PFP rehab

A
  • avoid exacerbating activities
  • improve lower limb mechanics and NM control
  • improve hip strength and quad strength
  • correct patellar positioning and tracking
  • stretching and mob of quads, HF, calves, hip, lumbar, ankle, knee joints

Q

explain patellar subluxation/dislocation

A
  • lateral displacement most common
  • commonly occurs with knee in 20-30 degrees of flexion but may also have valgus load at knee
  • may have associated fracture of patella, osteochondral fracture of patellar or femur and/or chondral defect

noncontact injury: femur goes into IR and adduction with very strong quad contraction
if they have had dislocation: get imaging

what are the structural patellar instability risk factors?

A
  • patellar hypermob
  • increased q angle
  • shallow trochlear groove
  • flat patella

- hip msucle weakness

Q

what is the q angle?

A
  • ASIS to middle patella to tibial tuberosity
    males: 10-14
    females: 15-17

Q

what happens wtih patellar subluxation/dislocation

A
  • effusion
  • common damage to distal attachment of medial quad tendon
  • medial retinaculkum and medial patellofemoral ligament damage
  • evaluated w apprehensino test and moving/dynamic patellar apprehension test

Q

what is post patellar subluxation/dislocation rehab?

A
  • R/O fracture
  • reduce effusion by RICE
  • restore rOM and muscle function (full ROM at 8-10 weeks)
  • brace if unstable
  • correct altered movement patterns

to reduce dislocation: extend knee and push patella medially
