Intra patellar bursitis clinical features
Clergymans knee Above the patellar lig Pain just bellow knee cap Swelling Kneeling
ACL rupture clinical features
LFC-> anterior tibia 50% also have a meniscal tear Fixed foot with knee flexion and internal hip rotation Felt pop Deep knee pain 70% immediate swelling
ACL rupture specific tests
Anterior draw test-> no end point and pain
Lack mans -> hold leg with knee in 30 flexion and pull tibia anteriorly
ACL rupture investigations
X RAY -> segond # convulsion proximal tibia
MRI
ACL rupture management
Conservative
- activity modification
- physio
- analgesia

Meniscal injury clinical features
Common with ACL rupture
Medical more common
