ACL in tumbles where the ski had rotated too far. Physical exams revealed that 10 of the 11 patients still had Lachman scores of 0-1 and negative pivot shifts tests, indicating a healed ACL, and only one patient's scores had deteriorated to a Lachman Grade 2+. None of the patients, however, complained about knee instability. Eight had returned to skiing without the use of a brace and three no longer skied. KT-1000 test results were also positive. "The mean difference was one millimeter, which is very close to perfect. Anything three millimeters or less is considered a successful result after surgery. In 10 of the 11 patients, their knees were rock solid, as good or better than surgery," said Dr. Marx.

Dr. Marx pointed out that the median age of the 11 patients was 43 and recovery from an ACL surgery at this age can sometimes be difficult. "For people who are 40 and over and who have less muscle mass, it takes a long time to recover, sometimes a year. Compare that to 12 weeks," said Dr. Marx. Identifying patients who can heal without surgery reduces medical costs and patient recovery time.
