title: Modified uniportal endoscopic plantar fasciotomy: a technical report.
abstract: OBJECTIVE
  Several authors have reported the benefits of the recent procedure of the dual portal endoscopic plantar fasciotomy (EPF). However, very little is known concerning its potential capability via the single portal EPF without special cutting device. The present study aimed to demonstrate the effectiveness of uniportal EPF in a patient with severe intractable plantar fasciitis following a failure of several conservative treatments. The recent technique; uniportal EPF under modified method, without a special cutting device, was reviewed in an effort to improve its capability for plantar release and to provide information for the avoidance of this procedure's complications.
  
  
  METHODS
  A patient, with the recalcitrant conditions and the progression of the severe plantar fasciitis of bilateral feet after a failure of the conservative treatments for 13-month period, was included in this report. All data of the preoperative and each successive postoperative period (1, 6 months and last follow-up) were prospectively collected including American Orthopedic Foot and Ankle Society (AOFAS) score, Visual Analogue Scale-Foot and Ankle (VAS-FA) score and any related complications. The operations were carried out by a single surgeon with the modified uniportal EPF via a simple hooked soft-tissue blade, without a special cutting device, on both feet simultaneously. All feet had uniportal EPF with transection of the medial 50% of the plantar fascia. Postoperatively, a patient was instructed to have partial-weight bearing for the first 2 weeks with wearing of full-length silicone insoles. Then, she is allowed to start to fully weightbear with the insoles. She is advised to cautiously return to daily activities and works at 2nd week after the operation. In regard to the EPF in two feet, there were clearly improvements in the comparison between preoperative and last follow-up period in terms of the increasing AOFAS scores, and VAS-FA scores. There were no significant iatrogenic-related complications including the lateral column pain in the present report.
  
  
  CONCLUSIONS
  The recalcitrant condition of severe plantar fasciitis is not uncommon for several orthopedic surgeons. Regarding the emerging of several minimally invasive procedures for this condition, our modified uniportal EPF with a simple device was encouraging as a treatment option in releasing the plantar fascia with satisfactory effectiveness and lower risks of complications.
