The Integrity after Arthroscopically Repairing the Rotator Cuff Tendon Using the Suture Bridge Technique
Abstract
Purpose
We evaluated the integrity after repairing the arthroscopic rotator cuff tendon using the suture-bridge technique in patients with full thickness rotator cuff tendon tears.
Materials and Methods
Forty two (males: 14, females: 28) consecutive shoulders that were treated with this index procedure and that had magnetic resonance imaging (MRI) taken at a mean of 9 months postoperatively were enrolled to estimate the postoperative intregrity of the repair. The mean age was 57 years (range: 44-75 years) and the mean follow-up period was 14 months (range: 12-16 months). The follow up MRI was evaluated using the Sugaya classification for postoperative cuff integrity. The clinical outcomes were evaluated by using the University of California Los Angeles (UCLA) score, the Korean Shoulder Scoring System (KSS) and Visual Analogue Scale (VAS). Significance was set at p values < 0.05
Results
In the 42 cases with follow up MRI, the cuff integrity was graded as type I in 10 cases, type II in 28, type III in 2, type IV in 1 and type V in 1 case. Out of the 39 cases having a medium to large tear, the type I and II cuff integrity was 92.3% and two patients had type III cuff integrity postoperatively, while the rate of retear was 33.3% (1 of 3) in the cases with massive tear. The overall rate of retear was 4.8%. For the intact postoperative repair rate, the precent of cases with fatty degeneration of grade 3 or less seen on preoperative MRI was 92.7%. For 41 patients, except for 1 case of type V retear, the UCLA score and the KSS score were significantly improved (p < 0.05) from 17.2 to 31.4 and from 58.2 to 90.8 on average, respectively, which showed satisfactory clinical outcomes regardless of the type of repair integrity.
Conclusion
The arthroscopic suture-bridge technique resulted in intact repair integrity in 90.4% of the cases and improved clinical outcomes, so we think this technique is one of the reliable procedures for treating full-thickness rotator cuff tear.

(B) Repair integrity: White arrow head indicates Sugaya classification type III in follow-up MRA taken 6 months postoperatively.
