Wound assessment is essential to effective wound management, and wounds should be measured each time the wounds are assessed.
Wound measurement provides baseline information while continuous measurement helps to predict healing and aids monitoring of treatment efﬁcacy and evaluation. It is also objective and can be useful in cost-beneﬁt analysis.
"What I did was to take picture of some wounds, where I placed a ruler near, and then measured the size of the wound with the KLONK software. I made it work without any problems, and I did not need any instructions. So the software is user friendly. I recommend to measure wound sizes on a regular basis. It should be done a lot more than it's done today."
Arne Langøen, Chairman of Norwegian Woundcare association (NIFS)
Why use Image Measurement to measure the sizes of wounds?
Tests demonstrated that wound margin advance, initial healing rate, percent wound surface area reduction, and wound healing trajectories (all p<0.001) were powerful predictors of complete wound healing at 12 weeks. (Early healing rates and wound area measurements are reliable predictors of later complete wound closure, Advanced BioHealing NY, 2008)
KLONK Image Measurement has been used in research projects for measuring the development in sizes of wounds. The tool has been used in different projects in hospitals in Europe to validate measurements and healing methods. Our software does not only help measuring, but are also focusing on giving a user-friendly way of keeping track of patients and document healing rates.
Studies have shown that the photographic method is an accurate alternative to contact methods, for measuring wound area, with no statistical difference in wound area measurement demonstrated during this study. The photographic method is a more appropriate technique for clean and uncontaminated wounds as contact with the wound bed is avoided, negating the risk of wound contamination, wound bed damage, and patient discomfort.

How to measure the size of a wound
In order to use KLONK Image Measurement to measure the size of wound you must follow the following procedure:
- Download and register KLONK Image Measurement
- Acquire an image with a digital camera, a mobile device or live video source, with a ruler (or another object with a known dimension) next to the wound.
- The image must be taken in an perpendicular angle
- Import the image from the camera or mobile phone to KLONK Image Measurement
- Calibrate the image size, according to the length of the known calibration object or ruler
- Draw the outline of the wound
If many measurements should be handled in large clinics or research projects, we recommend using KLONK Image measurement Scientific or Central. It includes report generation, area tracking curves and stores images in a database for better statistical handling. KLONK Image Measurement Central also has the possibility to be used as a multiuser system.
