Clinical outcome measures included range of motion, the visual analog scale (VAS) for pain, and the Constant score for function. Repair integrity was evaluated on magnetic resonance imaging scans using the Sugaya classification. Retears were also classified according to their pattern as type 1 (lateral) or type 2 (medial).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Overall, 88 patients (group 1: n = 42 [mean \u00b1 SD age, 54.3 \u00b1 9.8 years]; group 2: n = 46 [mean \u00b1 SD age, 55.8 \u00b1 8.2 years]) were included in the final analysis. The mean \u00b1 SD follow-up period was 25.4 \u00b1 8.3 and 23.3 \u00b1 7.2 months for groups 1 and 2, respectively. From preoperatively to postoperatively, the mean VAS pain score improved significantly in both groups (group 1: from 7.4 \u00b1 1.7 to 1.0 \u00b1 1.7; group 2: from 7.1 \u00b1 1.9 to 1.3 \u00b1 2.0; P &lt; .0001 for both), as did the mean \u00b1 SD Constant score (group 1: from 51.7 \u00b1 13.4 to 86.0 \u00b1 11.5; group 2: from 49.4 \u00b1 18.4 to 87.2 \u00b1 14.8; P &lt; .0001 for both). There was no significant difference between the groups for the postoperative VAS or Constant score. The retear rate was not significantly different between the groups (19.0% [8\/42] in group 1 and 28.3% [13\/46] in group 2; P &gt; .05).
