One-stage arthroscopic reconstruction of both cruciate ligaments using Achilles tendon-bone allografts / 中华创伤骨科杂志

ABSTRACT

Objective To evaluate one-stage arthroscopic reconstruction of anterior crueiate ligament (ACL)and posterior cruciate ligament(PCL)using Achilles tendon-bone allografts. Methods From July 2000 to February 2005.we treated 15 patients(11 males and 4 females)whose ACL and PCL were ruptured at one knee but the eontralateral knee was intact.Their associated meniscus injuries were treated arthroscopically according to established procedures prior to ligament reconstruction.Thirty Achilles tendon-bone allografts were used to reconstruct torn ACL and PCL in 15 knees at one stage.Reconstruction of both ligaments was performed at subacute or chronic phase(>3 to 8 weeks)in 12 casses,and at acute phase in 3 cases(<3 weeks).All knees were graded pre-and postoperatively using the International Knee Documentation Committee(IKDC)and Lysholm scoring systems.At follow-up,functions were evaluated for all patients and compared with those of the contralateral healthy knee. Results All patients were followed up for a minimum of 3 years(mean,38 months).Preoperatively,the IKDC ratings showed all the injured knees were severely abnormal.At final postoperative f0Uow-up,9 knees received a normal rating,5 a nearly normal one and 1 an abnormal one.The differences in Lysholm score were statistically significant (t=15.660,P<0.05)between pre-and postoperative analyses.The most noticeable postoperative complication was a short localized fever coupled with arthroedema in 1 case. Conclusions Achilles tendon-bone allograft offers an alternative for simultaneous arthroseopic reconstruction of ACL and PCL.However,problems inherent in allograft tissues entail further investigation to ensure future application.
