Abstract
Aim: The purpose of this study was to evaluate the results of transphyseal ACL reconstruction technique in skeletally immature patients.
Material & Methods: Between 2002 and 2008, twenty knees in twenty skeletally immature patients with a mean chronological age of 13.2 years (range, 7 to 16.2 years) underwent transphyseal reconstruction of the anterior cruciate ligament with use of an autogenous quadrupled hamstrings-tendon graft with metaphyseal fixation. Ten knees had additional meniscal surgery. The functional outcome, graft survival, radiographic outcome, and any growth disturbance were evaluated at a mean of 2.2 years (range, 1.0 to 5.9 years) after the surgery.
Results: No patient underwent revision anterior cruciate ligament reconstruction. The mean International Knee Documentation Committee subjective knee score (SD) was 90.5 (10.0) points and the mean Lysholm knee score was 92.2 (10.0) points. The result of the Lachman examination was normal in 18 knees and nearly normal in two; it was not abnormal or severely abnormal in any knee. The mean increase in total height was 7.2 cm (range, 1.2 to 20.4 cm) from the time of surgery to the time of final follow-up. No angular deformities of the lower extremity were measured radiographically, and no lower-extremity length discrepancies were measured clinically. Complications included one case of knee stiffness requiring physiotherapy, one case of persistent pain leading to medial menisectomy for tear and one case of re-injury five months post ACL reconstruction requiring medial meniscus repair.
Conclusion: Excellent functional outcome was noted in skeletally immature patients after transphyseal reconstruction of the anterior cruciate ligament with use of an autogenous quadrupled hamstrings-tendon graft with metaphyseal fixation. There were very few complications and no growth disturbance.
