Background: A treatment algorithm and screening examination have been developed to guide patient management and prospectively determine potential for highly active individuals to succeed with nonoperative care after anterior cruciate ligament rupture.
Objective: To prospectively characterize and classify the entire population of highly active individuals over a 10-year period and provide final outcomes for individuals who elected nonoperative care.
Methods: Inclusion criteria included presentation within 7 months of the index injury and an International Knee Documentation Committee level I or II activity level before injury. Concomitant injury, unresolved impairments, and a screening examination were used as criteria to guide management and classify individuals as noncopers (poor potential) or potential copers (good potential) for nonoperative care.
Results: A total of 832 highly active patients with subacute anterior cruciate ligament tears were seen over the 10-year period; 315 had concomitant injuries, 87 had unresolved impairments, and 85 did not participate in the classification algorithm. The remaining 345 patients (216 men, 129 women) participated in the screening examination a mean of 6 weeks after the index injury. There were 199 subjects classified as noncopers and 146 as potential copers. Sixty-three of 88 potential copers successfully returned to preinjury activities without surgery, with 25 of these patients not undergoing anterior cruciate ligament reconstruction at the time of follow-up.
Conclusion: The classification algorithm is an effective tool for prospectively identifying individuals early after anterior cruciate ligament injury who want to pursue nonoperative care or must delay surgical intervention and have good potential to do so.

Tapping Nature’s Secrets For Building Tiny ToolsCategory: Biology / Biochemistry | Leave a Comment |
Next time you have an unlucky encounter with a crab’s pinchers, consider that the claw tips may be reinforced with bromine-rich biomaterial 1.5 times harder than acrylic glass and extremely fracture resistant, says a University of Oregon scientist. Residents on the U.S. West Coast may have had close encounters with the biomaterial — detailed by a seven-member team in a paper published online in advance of regular publication in the Journal of Structural Biology.

World’s Smallest Periscopes Invented By Vanderbilt ScientistsCategory: Medical Devices / Diagnostics | Leave a Comment |
A team of Vanderbilt scientists have invented the world’s smallest version of the periscope and are using it to look at cells and other micro-organisms from several sides at once. “With an off-the-shelf laboratory microscope you only see cells from one side, the top,” says team member Chris Janetopoulos, assistant professor of biological sciences. “Not only can we see the tops of cells, we can view their sides as well - something biologists almost never see.
