Suture Bridge Technique

Background: Compared with the single-row technique, the double-row rotator cuff repair technique is known to have a higher load to failure and a lower frequency of gap formation, leading to a lower retear rate. There are some patients with poor clinical outcomes or poor muscle strength without radiologic retear. Purpose/Hypothesis: To assess the postoperative position of suture knots via serial ultrasonography in patients who had undergone arthroscopic rotator cuff repair with the suture-bridge technique. Our hypothesis was that the suture would pull out of the lateral anchor (suture slippage), changing the positions of the medial suture knots during healing. Study Design: Case series; Level of evidence, 4. Methods: This study included 53 patients (55 shoulders) who underwent arthroscopic suture-bridge repair and were evaluated for a minimum of 24 months. On serial ultrasonography, a straight line was drawn between the top of the greater tuberosity and the medial cortex of the anchor hole. The distances between the knots of the medial rows and the perpendicular line through the center of the anchor hole were measured in longitudinal plane images of the supraspinatus. Follow-up ultrasonography was performed at 2, 3, and 6 months postoperatively as well as at the final visit. The visual analog scale, the American Shoulder and Elbow Surgeons score, the Constant score, and the University of California, Los Angeles shoulder score were recorded preoperatively and on the final follow-up. Results: Of the 55 shoulders, 6 developed retears at repaired sites. The mean follow-up duration was 37.5 months (range, 24-65 months). Slippage distance increased significantly over time ( P < .001). The slippage at the final visit did not differ between patients with retear and no retear (13.4 mm for retear group; 10.6 mm for no retear group [ P = .096]). Conclusion: Suture knots of the medial row migrated medially via a suture pullout from the lateral row anchor of suture-bridge technique. Suture slippage distance did not differ significantly between retear and no retear groups.

Background: Type 2 failure is a big issue after suture-bridge rotator cuff repair, which may be because of stress concentration at the medial row stitches. We have been performing medial knot-tying after suture-bridge lateral row repair to avoid the stress concentration. This study aimed to evaluate clinical and radiological outcomes after arthroscopic rotator cuff repair using this technique. Hypothesis: This technique would yield better radiological outcomes with a reduced type 2 failure rate compared with reported outcomes after conventional suture-bridge repair. Study Design: Case series; Level of evidence, 4. Methods: The inclusion criteria of this study were (1) full-thickness tears, (2) primary surgery, and (3) minimum 2-year follow-up with pre- and postoperative magnetic resonance imaging (MRI). We investigated active ranges of motion (forward elevation and external rotation), as well as the Japanese Orthopaedic Association (JOA) and University of California, Los Angeles (UCLA), scores preoperatively and at the final follow-up. Results: This study included 384 shoulders in 373 patients (205 men and 168 women) with a mean age of 65 years (range, 24-89 years) at the time of surgery. The mean follow-up was 29 months (range, 24-60 months). There were 91 small, 137 medium, 121 large, and 35 massive tears. Postoperative MRI scans demonstrated successful repair in 324 shoulders (84.4%, group S) and retear in 60 shoulders (15.6%). Among 60 retears, 40 shoulders (67%) had type 1 failure (group F1) and 20 shoulders (33%) had type 2 failure (group F2). Forward elevation and external rotation significantly improved after surgery ( P < .001 for both). Postoperative JOA and UCLA scores in group F2 were significantly lower than those in the other groups. Conclusion: The medial knot-tying after suture-bridge lateral row repair demonstrated excellent functional and radiological outcomes after surgery, with a retear rate of 15.6%. The type 2 failure showed significantly inferior functional outcomes; however, the rate of type 2 failure was less relative to previous studies using conventional suture-bridge techniques. Our technique could be a good alternative to conventional suture-bridging rotator cuff repair because it may reduce the rate of postoperative type 2 failure.

Purpose There is still conflicting evidence to support postoperative rehabilitation protocols using immobilization following rotator cuff repair over early motion. The objective of the study was to evaluate the evolution of pain, shoulder function, and patients' perception of their health status up to 1 year after cuff rotator repair and a standard postoperative rehabilitation protocol consisting of 4 weeks of immobilization followed by a 2-week assisted controlled rehabilitation. Methods Descriptive, longitudinal, uncontrolled case-series study was performed on 49 patients who underwent arthroscopic rotator cuff repair following traumatic or degenerative lesions. VAS scale for pain, Constant–Murley score for function, and SF-12 score for quality of life were used as outcome measures and were administered before the rehabilitation treatment, at the end of the 2-week rehabilitation, 3 months, and 1 year after surgery. Results VAS pain score decreased significantly along the follow-up reaching almost a nil value after 1 year (0.2). Function as measured by Constant–Murley score had a significant improvement during follow-up, reaching a mean value of 84.6. The short form (SF)-12 score increased over time reaching 46.3 for the physical and 43.8 for the psychological dimension, respectively, at 1 year. Conclusion The present study confirmed an excellent outcome at 1 year after rotator cuff repair using a traditional 4-week immobilization followed by a 2-week rehabilitation protocol without evidence of tendon un-healing or re-tearing. Level of Evidence This is a level IV, therapeutic case series.
