Sensor Controlled Compliance Evaluation of Compressive Elastic Stockings
- Conditions
- Disorder of Ankle Joint
- Interventions
- Device: Compressive stocking
- Registration Number
- NCT02792907
- Lead Sponsor
- Balgrist University Hospital
- Brief Summary
Compressive stockings ameliorate functional outcome and quality of life in patients after elective orthopedic foot and ankle surgery. In this randomized controlled trial the investigators want to analyze the effect of compressive stockings after foot and ankle surgery. Additionally the investigators want to evaluate the compliance of the compressive stockings Treatment. Therefore an electronic chip device is implanted into the compressive stockings to monitor wearing time.
- Detailed Description
Pain and swelling are typical sequelae following surgical procedures at the foot and ankle. While it is known that compressive stockings treatment decreases swelling and improves overall ankle function and quality of life in patients after ankle fracture, the investigators hypothesize that compressive stockings could also ameliorate functional outcome and quality of life in patients after elective orthopedic foot and ankle surgery.
Reduced compliance in wearing compressive stockings after foot and ankle surgery might probably be a limiting factor of this postoperative adjuvant compressive therapy. Therefore the investigators want to evaluate patient´s compliance by using an electronic chip device to monitor wearing behavior.
All patients who will be operated on their feet and ankle are randomized and blindly assigned into either the compressive or control-group. Each group consists of 80 patients (160 patients in total). The compression group includes patients who receive postoperative compression stockings. The control group does not receive any stockings. Regular checks at 6 weeks and 12 weeks postoperatively will be performed in order to assess the following parameters:
1. Foot and Ankle Scores
2. Pain
2. Swelling of the foot and lower limb 3. Wearing compliance by electronically recorded wearing time.
The Information about the implanted sensor, which records the stockings wearing time will be given to the patients after the compressive stockings therapy (6 weeks), so that the patients are not influenced by the fact, that their wearing behaviour had been measured.
After this information, the patients decide if the sensor information may be evaluated by the study team or not.

Group Intervention Description Compressive Stockings group Compressive stocking Patients with compressive stockings at the operated foot for 4 weeks
- Primary Outcome Measures
Name Time Method Wearing Compliance 6 weeks postoperatively With a sensor the wearing time in hours/day is monitored. Patients will be informed about the sensor at the 6 week follow up. They will be asked if the study Team is allowed to read the monitored wearing time.
- Secondary Outcome Measures
Name Time Method worker´s compensation 12 weeks postoperatively % of ability to work the peroperative performed occupation.
Pain 12 weeks postoperatively Pain assessed in a visual analog scale ranging from 0-10 (0= no pain, 10= worst pain)
pain killer use 12 weeks postoperatively How many pills per day the patients require for the pain after surgery.
Swelling 12 weeks postoperatively Foot and ankle swelling measured in cm at defined Areas of the foot and ankle
AOFAS 12 weeks postoperatively American Orthopedic Foot and Ankle Score
