Autologous bone effects on femoral tunnel widening in hamstring anterior cruciate ligament reconstruction.

This study examines the hypothesis that autologous bone in the femoral tunnel for a hamstring anterior cruciate ligament (ACL) reconstruction will reduce femoral tunnel widening. Thirty-six patients undergoing hamstring autograft ACL reconstruction were randomized to 2 groups. One group underwent ACL reconstruction using EndoButton femoral fixation.

Quantitative morphology of full thickness rotator cuff tears.

The occurrence of full thickness rotator cuff tears (RCTs) at time of death, the size and distribution of those tears among the tendons of the rotator cuff, and the anterior to posterior and medial to lateral dimensions of the RCTs were determined. A subset of 57 shoulders from a group of 414 were found to have full thickness rotator cuff tears. The three-dimensional coordinates of specific bony landmarks and points defining the circumference of the RCT were digitized using a Flock of Birds DC electromagnetic tracking device.
