There are three major chronological groups of shoulder disorders, ie. instability, rotator cuff tear and osteoarthritis/cuff tear arthropathy. Ville Äärimaa's research touches upon eachs of these entities, but focuses especially on rotator cuff related problems. He has run in close collaboration with co-workers world's first randomized controlled effectiveness trial on treatment of non-traumatic rotator cuff tears and is now running a placebo controlled trial on efficacy of surgical repair of traumatic rotator cuff tears. In addition, he has run a trial on surgical treatment of shoulder instability and has studied the outcome and risks related to shoulder arthroplasty. He has helped to develop measurement methods of outcome after shoulder surgery and facilitated international collaboration and merging of uniform datasets.
