ORTHO Flashcards
RISK FACTORS FOR ACL INJURY
Young age (peak at 16-18 yrs)
Earlier, more intense, and more frequent participation in sport
Variations in bone morphology
Neuromuscular control
Genetic
Hormonal
Different types of meniscal surgery
Arthroscopy + Meniscectomy
Arthroscopy + Meniscus repair
What is an arthroscopy + meniscectomy?
Damaged cartilage is trimmed away
Arthroscopy + Meniscus repair
Sutured together
Autograft
tissue from own body
Allograft
tissue from cadaver
Pros / cons of HS autograft
Easier Sx to perform
↓ knee pain/stiffness post-op,
↓ hamstring strength
↓ incision and faster recovery
↑ laxity/potential graft
lengthening
Pros / cons of Quad autograft
Middle 1/3 of quadriceps tendon
Fixation not as solid
↑ post-op knee pain
↑ laxity/potential graft
lengthening
Pros / cons Patella tendon
Middle 1/3 of tendon
↑ pF knee pain (kneecap, kneeling)
↑ post-op stiffness
↓ knee laxity compared to other methods
COMPARE TRIAL for surgical / conservative management of ACL tear
(IMMEDIATE V DELAYED SURGERY) - 50% of patients randomised to three-months of rehab did not need surgery
Cross bracing protocol findings
90% of patients had evidence of healing on 3-month MRI (continuity of the ACL).
More ACL healing on 3-month MRI was associated with better outcomes.
What does the evidence say for meniscus surgery v conservative management for degenerative meniscal injury
strong evidence in favour of conservative management
MOI of ACL injury
deceleration, change of direction combined with knee valgus load
Common symptoms of ACL
hearing a pop or haemoarthrosis
Presentation of meniscus injury
pain, stiffness, catching/locking and instability
