Background:
Concern about growth disturbances around the knee after tra-
ditional ACL reconstruction in the skeletal immature patient has led to interest
in physeal sparing ACL reconstruction techniques. There is limited data that de-
scribe clinical results with these techniques.
Purpose / Aim of Study:
The purpose of the study was to describe the short-
term subjective and objective outcome after physeal sparing ACL reconstruc-
tion technique in skeletal immature patients.
Materials and Methods:
Until December 2015, 57 skeletal immature patients
underwent a physeal sparing ACL reconstruction using quadrupled Semitendi-
nosus autograft using the Flipcutter drilling system (Arhtrex) for the preparation
of bone sockets and Tightrope (Arthrex) as both femoral and tibial fixation. The
patients had a mean age at 13,5 (11-15) and were assessed preoperatively and
one year postoperatively using KT1000, manually pivotshift testing and PEDI-
IKDC. The results were compared to a comparable cohort of patients (N=42)
operated from 2001-2010 with a transphyseal technique using femoral endo-
button fixation and tibial extracortical fixation with washer and bicortical screw.
Findings / Results:
In the physeal sparing group the properative KT-1000 lax-
ity was improved from 4,6 to 1,6mm. In the historical group from 5,2 to 1,1
mm. (NS). We found pivot-shift more than grade 1 one year after surgery in
2/57 patients compared to 0/42 the historical group (NS). The mean PEDI IKDC
was after one year 86,6 (53-100) compared to IKDC in the historical group
78,6. (NS)
Conclusions:
We found good results after one year with physeal sparing ACL
reconstruction technique, but with no difference compared to a transphyse-
al technique. However, we describe early results and longer observation and
growth disturbance evaluation is needed to validate the future role of the phy-
seal sparing technique in ACL reconstruction in skeletal immature patients.
