Knee Flashcards
1
Q
how would you decrease risk for ACL injury
A
- focus on strength, neuromuscular control, balance
- series of different programs which address balance board training, landing strategies, plyometric training, and single leg performance
2
Q
examples of acute knee injuries
A
- ligamentous sprains
- mm strains
- contusions
- meniscal tears
- patellar dislocation
- fracturess
3
Q
examples of chronic knee conditions
A
- patello-femoral pain syndrome
- bursitis
- patellar tendonitis
- Osgood Schlatter’s disease
4
Q
general ligamentous sprains - grade 1
A
- no tearing
- no laxity
- mild stretching
5
Q
general ligamentous sprain grade 1 - management
A
- rest from sport 7-10 days
- RICE
- therapeutic modalities
- ROM and strengthening ex
- balance and prop ex
- maintain CR fitness (first thing that starts to deteriorate)
- tape for support
6
Q
general lig sprain - grade 2
A
- moderate damage with partial tearing
- some joint laxity present, but solid end feel noted
- slight swelling and increased pain
- moderate to severe joint tightness, decrease ROM
7
Q
management of general ligamentous sprain - 2nd degree
A
- POLICE 48-72 hours
- crutch use during acute phase
- rest from sport 2-4 weeks
- may brace prior to initiation of ROM ex
- gradual progression from isometric ex to closed kinetic chain progression activities
- maintain/regain CV conditioning/balance
8
Q
general ligamentous sprain - 3rd degree
A
- complete tear of supporting ligaments
- complete loss of stability during motion
- loss of motion due to effusion & guarding
- immediate pain that builds as swelling increase
- no ligamentous end feel at passive end range
9
Q
management ligamentous sprain, 3rd degree
A
- RICE
- conservative vs surgical approach
- limited immobilization with a brace
- progressive wbing and increase ROM over 4-6 weeks
- progress as per 1st and 2nd degree sprains
10
Q
MCL sprain - etiology
A
result from blow to lateral side causing tension on medial knee (valgus force)
11
Q
S&S MCL sprain
A
- swelling and pain dependent on severity
- pain on medial aspect of knee
12
Q
Etiology - LCL sprain
A
- result of varus force, generally w/ tibia internally rotated
13
Q
S&S LCL sprain
A
- pain, tenderness and swelling lateral joint line over LCL
- may cause irritation of peroneal nerve
14
Q
ACL sprain etiology
A
- caused by direct contact or by a non-contact mechanism
- 80% of cases result of non-contact
15
Q
ACL sprain - MOI
A
- deceleration
- hyperextension
- foot contacts the ground with the heel, or in a flat foot
- unhappy triad
- anterior force to tibia with the knee flexed to 90
- IR of leg w/ body in ER
- leg ER with valgus force
- cutting
