OBJECTIVE To assess autograft, homograft and ventricular function, as well as exercise capacity, in adult patients who have undergone the Ross procedure. SETTING Single centre paediatric and adult congenital heart disease unit. Patients 45 subjects (24.6 years, range 16.9-52.2 years) who underwent the Ross procedure between 1994 and 2006 (8.1 years after the Ross operation, range 2.0-14.0 yea...

The purpose of this study was to evaluate the osteointegration of a titanium (Ti) implant with the calcium phosphate cement (CPC) and autograft prostheses by pull-out test and histological examination. Stems of sixty Ti cylinders were bilaterally inserted into femoral medullary canals in 30 rabbits at the 1st, 4th, 12th, 26th and 70th postoperative weeks. The bone autograft and CPC were filled ...

BACKGROUND The treatment and rehabilitation procedures of anterior cruciate ligament (ACL) injuries in elite soccer players are controversial. Points of debate include surgical timing, technique, graft choice, rehabilitation, and return-to-sport criteria and timing. PURPOSE To identify practice preferences among current Major League Soccer (MLS) team orthopaedic surgeons for ACL injuries. S...

PURPOSE The purpose of this study was to analyze the clinical outcome of arthroscopic anterior cruciate ligament (ACL) reconstruction with bone-patellar tendon-bone autograft versus allograft. METHODS Between May 2000 and June 2004, 172 patients undergoing arthroscopic bone-patellar tendon-bone ACL reconstruction were prospectively randomized into autograft (n = 86) or allograft (n = 86) grou...

BACKGROUND Quadriceps tendon-patellar bone (QTPB) autograft is an excellent graft option with good clinical outcome. Use of QTPB autografts have increased because they minimize donor-site morbidity including anterior knee pain, while providing adequate mechanical strength. Although, there were many clinical results about allografts that used in anterior cruciate ligament (ACL) reconstruction, i...

BACKGROUND The purpose of the study is to report major cardiac and cerebrovascular events after the Ross procedure in the large adult and pediatric population of the German-Dutch Ross registry. These data could provide an additional basis for discussions among physicians and a source of information for patients. METHODS AND RESULTS One thousand six hundred twenty patients (1420 adults; 1211 m...

BACKGROUND The autograft preparation process for anterior cruciate ligament reconstruction has a potential for graft contamination. The purpose of this study was to evaluate the possibility of contamination of the bone-patellar tendon-bone and hamstring tendon autograft during preparation for anterior cruciate ligament reconstruction. METHODS A primary isolated reconstruction of the anterior ...

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 ...

The Ross procedure has emerged as a good alternative for aortic valve disease, particularly in children and young people in whom repair is not possible.1 Although the procedure is safe, complications related to the pulmonary autograft have been described.2 One of these complications has been reported on only two occasions,3,4 but was potentially severe: pseudoaneurysm of the autograft. A total ...
