Objective
To evaluate long-term prognosis of postoperative femoral neuropathy.

Method
15 patients who confirmed as femoral neuropathy by electrodiagnostic study after renal transplantation or abdominal hysterectomy were included in this study. Retrospective chart review and telephone interview of 12 available patients were performed at 36 months on average after operation. Second telephone interview were available in 4 out of 12 patients one year after first telephone interview. After the second telephone interview, we evaluated muscle strength and gait function of them in our labaratory.

Results
At immediate postoperative stage (average 16.8 days), knee extensor strength was less than grade III in 8 out of 12 patients. In gait function evaluation, six patients were unable to walk on flat surface. At first interveiw, recovery of muscle strength was excellent in five patients, good in five and fair in two. In gait function, all could walk without walking aids for more than 30 minutes and 9 could run and mount up the stairs. The second follow-up showed functional improvement even after 24 months of onset. The findings of physical examination correlated well with telephone interview.

Conclusion
Almost all patients who diagnosed as postoperative femoral neuropathy regained near normal motor strength and functional ambulation in the long-term follow- up. (J Korean Acad Rehab Med 2002; 26: 550-554)
