Allograft and bioabsorbable screw use in anterior cruciate ligament (ACL) revision surgery is common. However, both allograft and bioabsorbable screws have been associated with immunologic reactions that lead to tunnel enlargement. Long-term studies examining tibial tunnel enlargement in this population are currently not available. We report a case of severe tibial and femoral tunnel enlargement 6.5 years after ACL revision surgery with anterior tibialis and semitendinosus allograft and bioabsorbable screw fixation. Longitudinal knee arthrometer data, knee examination with the patient under anesthesia, and arthroscopic inspection of the graft showed minimal effects of severe tunnel enlargement on anterior knee laxity and graft integrity. To our knowledge, this is the first case report of a longitudinal assessment of anterior knee laxity associated with severe tunnel enlargement. Surgeons should be aware of this condition and the clinical consequences that may accompany bone tunnel enlargement after ACL surgery.
同种异体移植物和可吸收螺钉在前交叉韧带（ACL）重建手术中很常见。然而，同种异体移植物和可吸收螺钉都与免疫反应有关，导致隧道扩大。目前尚无关于该人群胫骨隧道扩大的长期研究。我们报告了一例 ACL 翻修术后 6.5 年出现严重胫骨和股骨隧道扩大的病例，使用前胫骨和半腱肌同种异体移植物和可吸收螺钉固定。膝关节纵向关节测量仪数据、麻醉下膝关节检查和移植物关节镜检查显示，严重隧道扩大对前膝关节松弛度和移植物完整性的影响很小。据我们所知，这是首例严重隧道扩大与前膝关节松弛度相关的纵向评估病例报告。外科医生应该意识到这种情况以及 ACL 手术后骨隧道扩大可能伴随的临床后果。
