To review outcomes of arthroscopic repair of rotator cuff tears using absorbable anchors with a single-row technique.
Methods.
66 patients underwent arthroscopic repair for rotator cuff tears using absorbable anchors with a single-row technique. 51 of them aged 37 to 73 (mean, 57) years had been followed up for a mean of 29 (range, 20–37) months. The extent of the tear was classified as large, medium or small. Functional outcome was assessed using the Constant score. Constant scores and re-tear rates in 3 patient groups (classified by patient age and tear size) were compared.
Results.
Among the 66 patients, there were 24 large, 29 medium and 13 small cuff tears, and a total of 48, 37, and 18 anchors were used, respectively. Among the 51 patients, the median Constant score improved significantly after arthroscopy (30 vs. 73, p<0.0001). Six shoulders had complete re-tears; their median Constant score was 48 and their adjusted Constant score was 65%. Complete re-tears occurred more often in patients aged >60 years than in those aged 50 to 59 years and <50 years (4/15 vs. 1/22 vs. 1/14), and more often in patients with large tears than in those with medium and small tears (4/24 vs. 2/29 vs. 0/13).
Conclusion.
Arthroscopic repair of rotator cuff tears using absorbable anchors with a single-row technique is reliable in patients aged <60 years with small or medium tears.
