Author | Year | Level of evidence | Sample | Follow-up | Technique | Outcomes | Conclusion |
---|---|---|---|---|---|---|---|
Vastamäki et al. [46] | 2013 | Level IV, therapeutic study | 67 patients Mean age 52 years |
Minimum 16 years Range 16-25 years |
Open repair | MR arthrography | 1) Re-tear rate 94%, Mean size of re-rupture (3,5x3,6cm) 2) 6% partial tear of supraspinatus 3) Fatty infiltration in supraspinatus and infraspinatus tendons 4) Active external rotation and forward flexion, strength of flexion, abduction and external rotation were better in patients with intact rotator cuff or small re-tear <4cm 5) Cuff integrity correlated with functional results several years postoperatively |
Park et al. [47] | 2013 | Retrospective level IV study | 36 patients with massive tear | 37,6 +/- 8,9 months | Arthroscopic suture bridge repair | US (4.5, 12 and 24 months postoperative) ASES, ROM, Constant and muscle power |
1) 25% recurrent tear, 75% complete healing 2) All functional scores improved, but the re-tear group (especially with large size) had poorer outcome than healed group (ASES P=0.005, Constant P=0.175) 3) Fatty degeneration of supraspinatus preoperatively associated with high re-tear rate |
Zumstein et al. [45] | 2008 | - | 27 patients with massive tear | 9.9 years | Open repair | Constant score Radiographs and MRI |
1) Re-tear rate 57% at 9.9 years and 37% at 3.1 years 2) Patients with an intact repair had better absolute and relative Constant score and abduction strength than those with failed reconstruction 3) Re-tear size increased from the initial 4) Supraspinatus and infraspinatus muscle fatty infiltration increased 5) Acromion index higher in re-tear group than intact group |
Yoo et al. [3] | 2013 | Level III cohort study | 81 patients | 29.7 months | - | SF-36 scores, UCLA, ASES | 1) 56/81 in healed group 25/81 in re-tear group 2) Clinical scores were significantly improved in both groups but significantly higher in the healed group |
Kim et al. [49] | 2014 | cohort | 180 patients | At least 1 year | - | US ASES, SST |
1) Clinical scores significantly poorer in the re-tear group (p<0,05) 2) Patients with a re-tear, non-anatomic factors including younger age, lower educational level and heavy workers were associated with poorer outcomes |
Lafosse et al. [50] | 2007 | - | 105 patients | - | Arthroscopic double-row repair | MRI arthrography, CT Constant score, muscle strength, ROM |
1) Superior clinical outcome in patients with healed repairs but not statistically significant 2) Pain relief in healed group (statistically significant p=0,014) |
