Knee: Treatment 2 Flashcards
PCL: nonsurgical
partial/full
typically partial tear only
PCL: nonsurgical
return to sport
Grade I
2-4 weeks
PCL: nonsurgical
Grade 3
immobilization?
immobilized in extension 2-4 weeks
PCL: nonsurgical
return to sport
Grade 3
~ 3 mos
PCL: nonsurgical
goals
- reduce swelling
- improve ROM
- begin strengthening (focus on quads)
PCL: nonsurgical
prognosis
most isolated PCL injuries return to full same/similar level sport
PCL: surgical
typical if there are
concomitant injuries
PCL: surgical
techniques
- commonly use Achilles tendon allograft
- two bundle technique is newer
PCL: surgical
rehab: need limitation of this motion
knee flexion
PCL: surgical
rehab
knee flexion ROM limited to 70˚ x how long?
2-4 weeks
PCL: surgical
rehab
Where in the ROM is the graft most taut?
70-90˚ flexion
PCL: surgical
rehab
limited resisted (motion) x 8 weeks
flexion
PCL: surgical
rehab
Why does resisted knee flexion need to be limited x 8 weeks?
protect against shear force and PCL load
PCL: surgical
rehab
major focus
quad strength
What does the posterolateral corner of the knee do?
provide static and dynamic stability to the knee
PLC: what movements does it prevent?
- hyperextension
- varus angulation
- tibial ER
PLC: components
- popliteus tendon
- popliteofibular ligament
- LCL
- arcuate ligament
- posterolateral capsule
- coronary ligament
- oblique popliteal ligament
- biceps femoris
- lateral gastroc head
PLC: (early/later) surgery is best
early
PLC: early surgery is best, especially for this structure (< 3 weeks)
LCL
PLC: rehab
goals
quad activation and ROM
PLC: rehab
WB?
NWB in knee immobilizer x 6 weeks to protect grafts
PLC: rehab
movements to avoid
- ER
- no isolated HS until > 4 mos
collateral ligaments usually managed (conservatively/surgically)
conservatively
collateral ligament:
With non-op rehab, should avoid these movements…for how long?
- varus/valgus
- excessive tibiofemoral rotation
6-8 weeks
collateral ligament: surgical
rehab
protection
protect surgical site - immobilizer or support brace
collateral ligament: surgical
rehab
WB
WB limited 0-30˚
2-6 weeks
collateral ligament: surgical
rehab
focus
quad strength
ROM
