This study prospectively evaluates the likelihood of a return of milit
ary personnel to full duty after anterior cruciate ligament reconstruc
tion. We report the results of 120 active duty military patients who u
nderwent anterior cruciate ligament reconstruction with autogenous pat
ella tendon. Mean follow-up was 29 months (range, 24-65 months), Time
from injury to reconstruction was >6 months in 90% of patients. Final
Lysholm scores averaged 89 (range, 29-100). We found that 77% of patie
nts returned to full duty, whereas 23% of patients were medically disc
harged from military service, The patient age, military rank, time fro
m injury to surgery, and KT-1000 measurements did not correlate with e
ither the Lysholm score or return to duty (p = 0.05). Severe chondroma
lacia (Outerbridge hi or IV) did correlate with poor result (p = 0.043
), and Lysholm score did correlate with return to duty (p = 0.003), An
terior cruciate ligament reconstruction offers a higher likelihood of
return to full military duty than nonoperative treatment in a similar
study.
