BACKGROUND Dilatation of the pulmonary autograft is a major concern after root replacement for the Ross operation. The inclusion technique would avoid this drawback, but few data are available on the long-term results of this technique. We retrospectively analyze long-term results of both techniques. METHODS Of 218 patients undergoing the Ross operation between 1991 and 2006, 148 (68%) had ro...

BACKGROUND Graft choice is very controversial. This study compared the second-look evaluation and clinical outcomes of anatomic ACL-R using a thin autograft versus a thick hybrid graft. MATERIAL AND METHODS Sixty-eight patients who had received ACL-R with hamstring autograft or autograft-allograft hybrid graft accepted second-look arthroscopy were grouped (autograft: n=31, age: 32.8±8.9, Male/F...

CONTEXT The advantages of allograft anterior cruciate ligament reconstruction (ACLR), which include shorter surgical time, less postoperative pain, and no donor site morbidity, may be offset by a higher risk of failure. Previous systematic reviews have inconsistently shown a difference in failure prevalence by graft type; however, such reviews have never been stratified for younger or more acti...

BACKGROUND Current use of Integra, the collagen-based dermal analogue, requires a two-step grafting procedure to achieve wound closure with an "ultrathin" autograft. METHODS A one-step operative procedure of meshed composite skin graft (MCSG) using Integra as a dermal template for a meshed split thickness autograft was developed in rats. The silicon layer of Integra was removed, the resulting...

Our aim was to compare the process of bone formation after reconstruction of the vertebral body using a titanium cage with either a liquid nitrogen-treated (frozen) bone autograft or non-treated fresh bone autograft. Twelve canine beagles underwent anterior reconstruction of the 5th lumbar vertebrae using a titanium cage and bone autograft. Bone formation was compared across four experimental g...

BACKGROUND Porous β-calcium pyrophosphate (β-CPP) was developed to improve the fusion success of posterolateral lumbar fusion (PLF). The possibility of accomplishing PLF using a mixture of porous β-CPP and iliac bone was studied. This paper reports the radiologic results of PLF using the β-CPP plus autograft for lumbar degenerative disease as a bone graft extender. METHODS A prospective, case...

background: peripheral nerves may be damaged during an injury and its current standard treatment is using an autologous nerve. objectives: the purpose of this experimental study is to evaluate and compare the histological results of nerve regeneration after using the eggshell membrane (esm) guidance channel with autograft. materials and methods: thirty adult male rats were divided into three ex...

OBJECTIVE To compare the fusion rate of a hydroxyapatite demineralized bone matrix (DBM) with post-laminectomy acquired autograft in lumbar interbody fusion surgery and to evaluate the correlation between fusion rate and clinical outcome. METHODS From January 2013 to April 2014, 98 patients underwent lumbar interbody fusion surgery with hydroxyapatite DBM (HA-DBM group) in our institute. Of t...

INTRODUCTION The aim of the study was to compare and analyze retrospectively the outcomes of arthroscopic posterior cruciate ligament reconstruction with autograft versus allograft. MATERIAL AND METHODS Seventy-one patients who underwent arthroscopic posterior cruciate ligament reconstruction with an autograft or allograft met our inclusion criteria. There were 36 patients in the autograft gr...
