Subjects with isolated symptomatic reparable supraspinatus tears smaller than 3\u00a0cm and without grade 4 fatty infiltration were included. These were randomized to two groups: In the Control group an arthroscopic supraspinatus repair was performed; in the Nanofracture group the footprint was additionally prepared with nanofractures (1\u00a0mm wide, 9\u00a0mm deep microfractures). Clinical evaluation was done with Constant score, EQ\u20105D\u20103L, and Brief Pain Inventory. The primary outcome was the retear rate in MRI at 12\u2010months follow\u2010up. Secondary outcomes were: characteristics of the retear (at the footprint or at the musculotendinous junction) and clinical outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seventy\u2010one subjects were randomized.
