There were 5 prospective and 13 retrospective study designs. The overall study quality was poor according to the Modified Coleman Methodology Score. Of the 954 repairs, 81% were complete repairs and 19% were partial repairs. The follow\u2010up range was between 33 and 52 months, and the mean duration between symptom onset and surgery was 24 months. Single\u2010row repairs were performed in 56% or patients, and double\u2010row repairs were performed in 44%. A pooled analysis demonstrated an improvement in visual analog scale from 5.9 to 1.7, active range of motion from 125\u00b0 to 169\u00b0, and the Constant\u2010Murley score from 49 to 74.
