Surgical techniques include bare sclera excision, excision with simple conjunctival closure, excision with the administration of antimetabolite adjuvants, excision with conjunctival autograft
and excision followed by amniotic membrane transplantation.
Taylor and colleagues (26) performed a randomized controlled trial of BPTB and HS autografts
fixed using similar femoral and tibial fixation methods and found that both grafts provided similar objective, subjective, and functional outcomes at an average of 36 months post-reconstruction.
The bone-patellar tendon-bone (BPTB) and HS tendon autografts
are the most common grafts in ACL reconstructions.
25% (1/16) with the skin substitutes and 30% (305/1,008) with the autografts
(P value less than .
For the first time, surgeons can have an allograft with strength qualities equivalent to an autograft
that is also truly sterile.
Ipsilateral bone-patellar tendon-bone (BPTB) autografts
were used for reconstruction in 72 patients; the remaining 41 patients, referred to as the hamstring tendon autograft
(HT) group, had reconstruction with either ipsilateral triple semitendinosus autografts
(32) or quadruple semitendinous autografts
Although Ross procedure, a method for pulmonary autograft
replacement of the aortic valve, had been first described in 1967, it had not been frequently applied till 1997 when long-term success reports were published (1).
Finally, considering that bone autografts
require so much operating-room time to prepare, the choice of ready-to-use titanium implants may prove to be no less cost-effective.
In a study of 40 patients with pulmonary autografts
and 40 with mechanical valves; the former group reported higher scores on measures of psychological health, physical functioning, physical pain,, and their general perception of their health status.
Enrollment of all 20 subjects is now complete and 19 of 20 patients avoided the need for painful autograft
surgery and regrafting at their StrataGraft-treated sites.
Several methods were implemented with the aim of improving the success rates, among them conjunctival autograft
was one of the recent recommended techniques.
3) Allografts offer several potential advantages over autografts
in anterior cruciate ligament reconstruction, including the absence of donor site morbidity, shorter operative times, improved cosmesis, and easier rehabilitation.
Nonetheless, experience with root remodeling in dilated autografts
has grown from the stage of anecdotal reports to the stage of selected clinical series (5).
Allografts offer several benefits over autografts
(grafts from the patient's own body), including expanded grafting possibilities, significantly decreased patient pain and reduced length of hospital stay.
et al (1998) retrospectively studied efficacy of conjunctival limbal autografts
for primary and recurrent pterygia in 53 eye of 51 patients.
