All patients underwent a standardized comprehensive rehabilitation program postoperatively.

In comparing strength deficits, we found no difference in slow isokinetic extension strength (22.4% vs 27.8%,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .51), fast isokinetic extension strength (18.5% vs 12.5%,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .41), slow isokinetic flexion strength (11.0% vs 15.1%,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .55), and fast isokinetic flexion strength (8.2% vs 4.9%,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .56) in the femoral nerve block versus control groups, respectively.

Maximal strength noted to be within 15% of the contralateral limb was achieved in 40% of patients and maximal function in 63% of patients at an average of 10.6\u00a0months postoperatively. A 13% complication rate was found in patients who received a femoral nerve block (1 with prolonged quadriceps inhibition and 2 with prolonged sensory disturbances).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our study found a 13% motor\/sensory complication rate in patients who underwent femoral nerve block for pain control after anterior cruciate ligament reconstruction.
