Improved ACL reconstruction outcome using double-layer BPTB allograft compared to that using four-strand hamstring tendon allograft

摘要: Abstract Background This study compared the clinical outcomes of anterior cruciate ligament reconstruction using double-layer bone–patellar tendon–bone (DBPTB) allografts and four-strand hamstring (4SHS) grafts. Methods prospective randomized controlled trial included 101 patients. Of these, 50 patients received DBPTB allografts, 51 4SHS Evaluations KT-1000 arthrometer measurements, Lachman tests, pivot-shift International Knee Documentation Committee (IKDC) classification Lysholm scores at three year postoperative follow-up. Results Two (four percent) nine (17.6%) had graft failures, which was significantly different ( P =0.028). The group better test, IKDC knee score results than Conclusions fewer failures years grafts for reconstruction; there were statistically significant differences but not clinically between in terms KT1000 scores.
