title: Tendoscopic treatment of intrasheath subluxation of the peroneal tendons.
abstract: BACKGROUND
  Intrasheath subluxation of the peroneal tendons does not have an injury of the proximal retinaculum. The aim of this study was to describe the tendoscopic technique and preliminary results.
  
  
  METHODS
  Six patients with intrasheath subluxation of the peroneal tendons were treated tendoscopically. All patients had preoperative pain and a clicking sensation at the lateral retromalleolar area. Mean followup was 18.3 (range, 14 to 24) months. These six patients included three males and three females, with a mean age of 23.5 (range, 18 to 33) years. The AOFAS and Visual Analog Score for pain were used to evaluate the patients.
  
  
  RESULTS
  During tendoscopy, two patients had a peroneus quartus tendon which was removed; three had a low-lying peroneus brevis muscle that was resected; and in two cases deepening of the peroneal groove was performed. At followup, all patients reported excellent results, without pain or clicking sensation. The mean AOFAS score increased from 79 to 99, and Visual Analog Score at followup was 0 in four patients and 1 in two patients.
  
  
  CONCLUSIONS
  Tendoscopic treatment of these pathologies led to improved function in a less aggressive manner than open surgery.
