Increased stability has been reported with both autografts and allografts for anterior cruciate ligament (ACL) reconstruction. However, meta-analysis has shown significantly lower overall knee stability rates and more than double the abnormal stability rate with allografts. Some issues surrounding allograft sterilization (ie, risk of disease transmission) are unresolved, and cost is also a conc...

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...

BACKGROUND AND AIMS Autogenous bone graft is commonly used for reconstruction of bone defects in routine surgical procedures. The complexity of producing bone grafts and their application has lead to the use of human bone matrix gelatin (HBMG). The present study was conducted to compare the efficacy of HBMG and autograft on the reconstruction of bone defects in rats. MATERIALS AND METHODS In ...

PURPOSE To report the incidence of recurrence after primary pterygium surgery using either a free conjunctival or limbal-conjunctival autograft without antimetabolites. METHODS One hundred eleven eyes of 90 patients underwent pterygium resection; a free conjunctival autograft was used in 88 surgeries and a free limbal-conjunctival autograft in 24; the latter technique was reserved for dark-sk...

CONTEXT In some cases, synchronous superior mesenteric-portal vein resection can be performed during pancreatic resection for cancer. The reconstruction technique is usually primary anastomosis; in only a few cases is an autologous vein graft needed. CASE REPORT We report a case of reconstruction of the superior mesenteric-portal vein with a splenic vein autograft in a patient affected by pan...

BACKGROUND Dilatation of the pulmonary autograft is a major drawback of the Ross procedure and it is the leading cause for reoperation in these patients. CASE PRESENTATION In this report we describe 3 cases reports, each one with a different outcome, of patients that underwent the Ross procedure. CONCLUSIONS In order to prevent any lethal or non-lethal complications of the pulmonary autogra...

Background Quadrupled (4-strand) hamstring tendon autografts are commonly used in anterior cruciate ligament (ACL) reconstruction, but there is significant variability in their diameter. The 5-strand hamstring autograft has been used as a means of increasing the graft diameter in patients with undersized hamstring grafts. Purpose To report the outcomes of primary ACL reconstruction using 5-st...

BACKGROUND The effect of low-dose gamma irradiation on healing of soft tissue allografts remains largely unknown. HYPOTHESIS The authors hypothesized that soft tissue allograft healing to bone would be delayed compared with that of autograft tissue and that low-dose (1.2 Mrad) gamma irradiation would not affect the healing response of allograft tissue after anterior cruciate ligament (ACL) re...

OBJECTIVE Significant dilation of the pulmonary autograft is problematic after the Ross operation and may require reoperation. Pulmonary autograft remodelling occurs in response to the immediate rise in pressure and consequently wall stress. Stress-strain response of the pulmonary root plays an important role in understanding autograft function and remodelling following the Ross procedure. Howe...
