The effect of femoral guide rotation in endoscopic anterior cruciate ligament (ACL) reconstruction is reviewed based on a previous report. The effect of varied offsets of the femoral guide (5.5 and 7.0 mm) are described. This is one of the few isometry studies to evaluate the knee through a practically full range of motion (0 degree-120 degrees). A 7-mm offset guide rotated to the 12:00 position yields the best single fiber and graft excursion patterns (P < 0.05). A 5.5-mm offset guide yields inferior single fiber and graft excursion patterns. Single fiber and graft isometry are similar but not identical in endoscopic ACL reconstruction. Centering the single fiber in the tibial tunnel has little effect on isometry patterns, demonstrating that the more posterior tibial positions needed for endoscopic reconstruction are acceptable from an isometry standpoint.

There were no significant differences in stability conferred by an external fixator or a T-POD for unstable pelvic injuries. We advocate acute, temporary stabilization of pelvic injuries with a binder device and early conversion to internal fixation when the patient's medical condition allows.

We advocate the placement of pelvic binder devices at the level of the greater trochanters for improved control of the fracture in an unstable pelvic injury. This may result in improved control of hemorrhage, better access to the abdomen, and greater patient comfort.
