Introduction: Percutaneous endoscopic lumbar discectomy (PED) is performed under local anesthesia and requires an 8-mm skin incision. PED is the least invasive disc surgery procedure, especially for back muscles. Although PED is the best approach for athletes, it is unknown PED available for top athletes.

Purpose: The purpose of this study is evaluation of the results after PED for top athletes.

Materials and Methods: Twenty-one male and one female top athletes with lumbar disc herniation underwent PED surgery under local anesthesia. The mean age was 25.2. The diagram of sports activity was 4 high school, 7 collage, 6 amateur player and 5 professional player. Operation time, Blood loss, complication, time to return to play, ratio of return to play and recurrence rate were investigated. The changes of Visual Analog Scale (VAS) for low back pain before and after surgery were reviewed.

Results: Postoperative course improved successfully. Mean operation time was 52 minutes. There was no complication. Time to return to their sport was from 5 to 8 weeks after surgery. The mean preoperative VAS score for low back was 6.5 and that of postoperative was 0.5, respectively. Although 2 cases showed recurrence, the postoperative course was good after second operation. Two patients were not able to return to own sports. The ratio of return to play was 91%.

Discussion: Our results showed much better than previous reports. PED is best surgical treatment for top athletes even if they need hard and tough activities after operation.

Conclusion: PED is the minimally invasive disc surgery, and provide better clinical results even in top athletes as compared to the traditional method of discectomy.
