Questions parents ask
What is the best treatment for a pediatric ACL tear?
There is no single answer — the right operation depends on how much growing the child has left to do. Where the growth plates are still open, Dr. Green uses physeal-sparing and all-epiphyseal techniques that work around the growth plate. In older adolescents he also uses quadriceps tendon grafts and lateral extra-articular tenodesis (LET). The decision begins with a precise diagnosis and his own independent review of the imaging, then what the child wants to get back to.
Is surgery needed for a discoid meniscus in a child?
Not in every case. A discoid meniscus is one that formed in a disc shape rather than the usual C shape. When it causes symptoms such as catching, swelling or pain, Dr. Green’s approach is saucerization — reshaping the meniscus — together with repair where the tissue allows it.
What is a tibial spine fracture in children?
It is also called a tibial eminence fracture. Rather than the ACL tearing in its mid-substance, the piece of bone where the ligament attaches to the top of the shin pulls away. It occurs in children because that bone is still developing. It is one of the injuries Dr. Green’s research has concentrated on.
What are the treatments for patella (kneecap) dislocation in children?
For recurrent instability Dr. Green performs MPFL reconstruction. Where the alignment of the bone is driving the dislocations, he also performs tibial tubercle osteotomy and Fulkerson osteotomy. Which applies depends on the diagnosis and on the imaging review.
