Purpose:
To determine if preoperative imaging findings of massive rotator cuff (RC) tears were associated with (1) incomplete arthroscopic repair and (2) the use of advanced mobilization techniques (interval slides) and/or the use of a load-sharing rip stop repair construct.
Methods:
Eighty-six consecutive patients who underwent arthroscopic repair for massive RC tears performed by a single surgeon between July 2013 and July 2015 were retrospectively evaluated. Previously proposed radiographic risk factors for irreparability (acromiohumeral distances, tangent sign, and the Goutallier stage of fatty infiltration for the supraspinatus) were analyzed. Associations between preoperative imaging characteristics and intraoperative results of RC surgery were determined using binary logistic regressions and Fisher's exact tests. The interobserver reliability of imaging characteristics was determined using intraclass correlation coefficients (ICCs).
Results:
Seventy-six massive RC tears were fully reparable (88%). In the case of 10 RC tears (12%), a complete repair was not obtained. Inability to obtain a complete repair of the supraspinatus was associated with a positive tangent sign (30% irreparable) versus a negative tangent sign (6.3% irreparable, odds ratio [OR] = 6.3, P = .0102) and with Goutallier grade 3-4 fatty infiltration of the supraspinatus (42.9% irreparable) versus grade 0-2 fatty infiltration (5.7% irreparable, OR = 11.8, P = .001). Advanced arthroscopic techniques (interval slides or load-sharing rip stop) for dealing with poor-quality or retracted tendon were used in 62% of cases; however, no associations were found between preoperative imaging characteristics and these techniques. Interobserver reliability was moderate (ICC = 0.75-0.90) for the tangent sign (ICC = 0.78) and high-grade (Goutallier 3-4) fatty infiltration of the supraspinatus (ICC = 0.74).
Conclusions:
A positive tangent sign and/or high-grade fatty infiltration (Goutallier 3-4) of the supraspinatus were risk factors for incomplete RC repair. However, these were not completely predictive of reparability because the majority of massive RC tears with these imaging characteristics were still fully reparable.
Level Of Evidence:
Level IV, therapeutic case series.
