For skeletally immature athletes, use of an all-inside ACL reconstruction technique demonstrated safety at short-term follow-up, according to study results.
Researchers prospectively evaluated 23 skeletally immature patients after all-inside ACL reconstruction, of whom 15 underwent an all-epiphyseal (AE) ACL reconstruction and eight underwent a partial transphyseal (PTP) ACL reconstruction. The researchers performed MRI using 3-D fat-suppressed spoiled gradient recalled echo sequences and full-length standing radiographs to assess graft survival, growth arrest, physeal violation, angular deformity and leg length discrepancy at 6 and 12 months postoperatively. Mean follow-up was 18.5 months.
Results showed 10 patients in the AE group and all patients in the PTP group experienced minimal tibial physeal violation. In the AE group, the researchers found a mean area of tibial physeal disturbance of 57.8 mm2 vs. 145.1 mm2 in the PTP group. One case in the PRP group and no cases in the AE group had a 1.5% compromise of the femoral physis.
MRI showed no cases of growth arrest, articular surface violation or avascular necrosis, and the researchers also observed no postoperative angular deformities or significant leg length discrepancies. – by Casey Tingle
