BACKGROUND Tunnel enlargement and coalition following double-bundle anterior cruciate ligament (ACL) reconstruction with hamstring tendon autografts has not yet been sufficiently studied. HYPOTHESIS The incidence and the degree of femoral tunnel enlargement will be significantly greater than those for tibial tunnel enlargement after anatomic double-bundle ACL reconstruction using hamstring te...

Anterior cruciate ligament graft choice is controversial, with no evidence-based consensus available to guide decision making. The study design was evidence-based medicine systematic review of randomized controlled trials evaluating patellar tendon versus hamstring tendon autografts. A literature review identified 9 randomized controlled trials comparing patellar tendon and hamstring tendon aut...

PURPOSE To report outcomes of revision anterior cruciate ligament (ACL) reconstruction using tibial or hamstring tendon allografts and to compare with another study using non-irradiated fresh-frozen bone-patellar tendon-bone allografts. METHODS Records of 12 men and 7 women aged 18 to 53 (mean, 33) years who underwent revision ACL reconstructions using tibial tendon (n=17) or hamstring tendon...

Despite spontaneous sprouting of peripheral axons after transection injury, peripheral regeneration is incomplete and limited to short gaps, even with the use of autograft tissue, which is considered to be the "gold" standard. In an attempt to obviate some of the problems associated with autografts, including limited donor tissue and donor site morbidity, we aimed to synthesize a synthetic nerv...

No instance of survival of spleen homeografts beyond the usual taking and persistence for 1 or 2 weeks common to most homeografts has been observed, although the possible advantages of consanguinity, age, and splenectomy were fully utilized. This is in sharp contrast to thyroid, sex gland, and adrenal cortex homeografts, with which one may expect 10 per cent to survive the 30 day period. It sug...

PURPOSE This study aimed to systematically review the highest level of evidence on anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone (BPTB) autografts with patellar tendon defect closure versus no closure after surgery. METHODS We performed a systematic review of multiple medical databases using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (P...
