ACL再建におけるsingle band, double bandの比較

Hamstringを用いたsingle bundle（quadruple）, double bundleおよび膝蓋腱によるACL再建の結果を5年後のdisease-specific quality-of-life outcomeで検討したRandomized Clinical Trial。結論としては"At 5 years, we found no significant difference in the quality-of-life outcome among the patellar tendon, hamstring tendon, and double-bundle techniques for ACL reconstruction. Significantly more patients in the hamstring tendon and double-bundle groups experienced traumatic graft reinjury compared with the patellar tendon group. There was a trend toward a higher percentage with normal and nearly normal IKDC grades in the patellar tendon group compared with hamstring tendon and double-bundle groups."ということでHamstring腱を用いた群ではreinjuryが多く、IKDC gradeが正常～ほぼ正常な患者は膝蓋腱群で多い傾向があったとのこと。
