MRI


Quality of MRI varies
Radiologists expertise
varies



400,000 reconstructions
per year in the US
Females 4 times more
likely to tear ACL with
non-contact injury
ACL Tears-Prevention


High intensity
plyometrics, balance
training, and
strengthening
Neuromuscular

Allograft
ACL tear-Growth Plates Open







6-12 weeks to heal

knee pain
Dull, aching pain
Worse with jumping,
climbing, squatting
Exam



Point tender at medial
patellar facet
View patellar tracking
Normal exam-think
about hip
Chondromalacia Diagnosis


