OBJECTIVE To compare the behavior of a tissue-engineered living skin equivalent (LSE) with an autograft in acute donor site wounds. DESIGN Paired-comparison, randomized control trial. SETTING A university dermatology service. PATIENTS Three donor sites were created on the anterior thigh of each of 20 patients requiring split-thickness skin grafts. INTERVENTION For each patient, the dono...

STUDY DESIGN A retrospective study. PURPOSE To investigate clinical and radiological outcomes when using spinous process as a tricortical autograft for segmental spinal fusion in transforaminal lumbar interbody fusion (TLIF). OVERVIEW OF LITERATURE Interbody spinal fusion is one of the important procedures in spinal surgery. Many types of autografts are harvested at the expense of complicat...

Pulmonary autograft valve replacement has been simulated by implanting the pulmonary valve into the aortic position of the same cadaver heart from both human and porcine sources. The forces acting on the pulmonary valve leaflets have been calculated on the basis of a triaxial ellipsoid mathematical model. These forces on the pulmonary autograft valve were shown to be essentially similar to thos...

BACKGROUND CONTEXT Conditions requiring posterior lumbar spinal fusion remain a clinical challenge. Achieving arthrodesis using autogenous bone graft is inconsistent when rigid internal fixation such as transpedicular instrumentation is applied. Synthetic materials, particularly calcium phosphate-based ceramics, have shown promise for spine fusion applications, especially when combined with aut...

Introduction. Although several intercalary reconstructions after resection of a lower extremity malignant bone tumor are reported, there are no optimal methods which can provide a long-term reconstruction with fewest complications. We present the outcome of reconstruction using a devitalized autograft and a vascularized fibula graft composite. Materials and Methods. We conducted a retrospective...

PURPOSE To investigate tibial tunnel widening and knee instability after ACL reconstruction with hamstring autograft or irradiated soft tissue allograft. METHODS Eight-two patients were divided into two groups: autograft group and allograft group. Radiographic and clinical evaluations were performed. RESULTS Seventy patients were followed up with median of 36.3 months (range 36-38 months). ...

OBJECTIVES For adult patients <60 years with aortic valve disease, the Ross procedure is an attractive alternative to a prosthetic aortic valve. The Ross procedure enables surgeons to achieve a haemodynamically ideal aortic valve replacement. A potential drawback may be long-term durability, which varies considerably between series. METHODS Between 1996 and 2014, 209 patients (mean age, 43 ± ...

BACKGROUND The use of a pulmonary autograft for rereplacement of the aortic valve has both potential advantages and disadvantages. This study details the early results of a subset of patients enrolled in a prospective randomized trial comparing pulmonary autografts and aortic homografts who have had previous aortic valve replacements. METHODS AND RESULTS A total of 47 patients who had undergo...

Harvesting the central third of the patellar tendon for autograft anterior cruciate ligament reconstruction is thought to compromise quadriceps strength and functional capacity. We compared objective measurements of quadriceps strength and functional capacity in athletes after patellar tendon autograft or allograft anterior cruciate ligament reconstruction. We looked at 33 active male patients ...
