Congenital knee dislocation

Tarek classification (based on amount of passive knee flexion)

•- Recurvatum >90
•- Subluxation 30-90
•- Dislocation <30
•Causes
•Packaging syndrome
•Arthrogryposis / Larsen syndrome
•Ehler-Danlos syndrome
•Look for other packaging dislocations
•Torticollis
•DDH
•CTEV
•Congenital vertical talus

Pathoanatomy

•Quadricep contracture
•Hamstring subluxed to anterior → extend knee
•Overall: extension moment

Management

•Conservative - 1st line
Brace / treatment image
Fig 1. Brace / treatment imagetop left
•Serial casting with gradual knee flexion
•Hip and knee dislocation
•Treat knee first otherwise wont fit in Pavlik harness (always associated with Graf 3 DDH)
•Operation
•Indication: failed 30 degrees knee flexion after 3 months casting
•Aim: soft tissue release to obtain 90 degree flexion – quad VY plasty
