We performed intra-articular reconstruction of the anterior cruciate ligament (ACL) with the semitendinosus tendon placed in 2 mm diameter tunnels in 21 skeletally immature rabbits. The operation caused 11% damage to the physis of the femur on the frontal plane and 3% of its cross-sectional area but no alteration of growth or axial deviation of the bone resulted. In the tibia, the operation caused 12% damage to the physis in the frontal plane and 4% of the cross-sectional area. Two tibiae developed valgus deformities and one was shortened. Histological examination showed no areas of epiphysiodesis. There was no abnormality of growth-plate thickness in the two cases of tibia valga. Osseous metaplasia in the grafted tendons did not occur. The results suggest the need for careful evaluation of the percentage of damage to the growth plate before using intra-articular methods for reconstruction of the anterior cruciate ligament in adolescents.
我们对21只骨骼未成熟的兔子进行了前交叉韧带（ACL）关节内重建，将半腱肌腱置于直径2毫米的隧道中。手术导致股骨骨骺在额平面上有11%的损伤，占其横截面积的3%，但未导致生长改变或骨骼轴向偏差。在胫骨，手术导致骨骺在额平面上有12%的损伤，占横截面积的4%。两根胫骨出现外翻畸形，一根胫骨缩短。组织学检查未发现骨骺闭合区域。两例胫骨外翻病例的生长板厚度无异常。移植肌腱中未发生骨化生。结果表明，在青少年使用关节内方法重建前交叉韧带之前，需要仔细评估生长板损伤的百分比。
