纽扣钢板悬吊固定自体胴绳肌肌腱前交叉韧带重建术后远端骨隧道填充磷酸三钙人工骨的临床分析

目的：判断微孔磷酸三钙（ mp-TCP）临床上是否可以有效促进腱骨愈合，提高膝关节稳定性，减少胫骨隧道的扩大，恢复关节功能。方法本研究对2007年6月至2008年10月，120例进行前交叉韧带（ ACL）自体腘绳肌肌腱重建手术的患者进行研究，随机填充mp-TCP，符合实验标准共105例患者。术后随访1年，进行临床、影像学指标统计分析。结果 TCP填充组及TCP非填充组两组在术后12个月的临床指标中，膝关节活动度（ ROM）、单腿跳跃检查、大腿周径差别、Lachman试验和轴移试验结果均无统计学差异；Tegner评分，Lysholm评分和IKDC主观功能量化评分统计学上也均无统计学差异（P＜0.05）；但是双侧膝关节前向松弛度差异（SSD）上则有统计学差异。重建术后影像学指标统计分析示骨隧道填充TCP可以有效减少术后骨隧道扩大的程度。结论前交叉韧带自体腘绳肌肌腱重建手术骨隧道填充TCP可以有效减少术后骨隧道扩大的程度。

Clinical effects of double-bundle four-tunnel eight-stranded autologous hamstring tendons technique in anterior cruciate ligament reconstruction using Tricalcium Phosphate in distal tunnel

Objective To investigate whether micropore-tricalcium phosphate （ mp-TCP ） can enhance the healing of bone-tendon after anterior cruciate ligament （ ACL ） reconstruction and promote the recovery.Methods From June 2007 to October 2008, 120 patients were operated with a double-bundle＆amp;nbsp;four-tunnel eight-stranded autologous hamstring tendons technique for anterior cruciate ligament reconstruction.105 pacients were chosen by the experimental standard .They were divided into the TCP group and the control group randomly , and the bone tunnels of the patients in the TCP group were filled with the mp-TCP.Results The diameter of the bone-tunnel in the TCP group was less than it in the control group.As for clinical examination , there was no difference between the two groups .Conclusion Micropore-tricalcium phosphate （ mp-TCP） can enhance the healing of bone-tendon after ACL reconstruction and promote the recovery .
