Background: A discoid lateral meniscus in the knee is more common Asian populations. The aim of this study was to evaluate influence arthroscopic meniscectomy on axial alignment lower limb adolescents (younger than twenty years age). Methods: We retrospectively reviewed data from 298 adolescent patients age) who underwent treatment our center 2004 2013. Patients were divided into three groups according type: torn (Group A), nondiscoid B), and without a tear C). tibiofemoral angle (TFA) mechanical axis deviation (MAD) both limbs examined standing anteroposterior radiographs before after arthroscopy. Results: preoperative TFA MAD ipsilateral demonstrated significantly varus Group B (p < 0.001) or C we controlled for contralateral as covariate factor. Moreover, knees reduced (indicating reduction inclination) postoperatively, compared with preoperatively, 0.001), no difference between postoperative values > 0.01), Additionally, reductions (varus greater those observed 0.001). Conclusions: altered immediately meniscectomy: deformity reduced, valgus inclination developed some these patients. pronounced meniscus. Level Evidence: Prognostic III.
