Objective[edit | edit source]

The Olerud-Molander Ankle Score (OMAS) is a self-reported outcome measure that assesses the symptoms and function of a patient following an ankle fracture. This scoring system was developed by Olerud and Molander in 1984 and was validated against (a) linear analogue scale (LAS) measuring subjective recovery, (b) range of motion in loaded dorsal extension, (c) presence of osteoarthritis and (d) presence of dislocations on radiographs. It has been found to correlate well with these four parameters.[1]

Intended Population[edit | edit source]

Individuals who have had an ankle fracture.

Method of Use[edit | edit source]

OMAS uses a summated rating scale format and consists of 9 questions:

  1. pain (0 to 25)
  2. stiffness (0 to 10)
  3. swelling (0 to 10)
  4. stair climbing (0 to 10)
  5. running (0 to 5)
  6. jumping (0 to 5)
  7. squatting (0 to 5)
  8. use of supports (0 to 10)
  9. work/activity level (0to20)

The highest possible score is 100 and higher scores indicate better outcomes
