The goal of this study was to evaluate the clinical and radiological results of the arthroscopic knotless-anchor Speed-Bridge technique, in particular the pattern and the rate of retears. The results were compared with a modified Suture-Bridge knot-tying technique (mDR). The hypothesis is that arthroscopic knotless-anchor Speed-Bridge rotator cuff repair is a sufficient technique to address supraspinatus tears and differs in pattern of retears when compared to mDR.

METHODS

This study includes twenty-two consecutive patients (8f/14m ø 63.3 ± 7.2 years) undergoing knotless-anchor Speed-Bridge repair. The subjective shoulder value (SSV), Constant score (CS) and Western Ontario Rotator Cuff (WORC) Score were used for clinical follow-up. MRI scans were conducted within 3 weeks post-operatively, after 1 and after 2 years for analysis of (a) tendon integrity (according to Sugaya), (b) muscle atrophy according to Thomazeau and (c) fatty infiltration. Results were compared with 20 patients operated in mDR (ø 61.2 ± 7.5 years).

RESULTS

The mean follow-up was 24.4 ± 4.7 months. The average SSV was 88.7 ± 14.9 %, the CS was 78.2 ± 13.2 points (contralateral side 78.5 ± 16.6) and the WORC Score averaged 87.1 ± 18.2 %. On magnetic resonance imaging, the integrity failure rate was 22.7 % (n = 5). The pattern of retear was a medial cuff failure in 2/5 cases (mDR 4/5, n.s.). Muscular atrophy or fatty degeneration did not increase between surgery and follow-up (n.s.). Compared with mDR (25 %) reconstruction, no significant differences were obtained regarding integrity failure rate and muscular atrophy (n.s.).

CONCLUSION

The modified knotless-anchor Speed-Bridge technique shows good to excellent clinical results as well as acceptable retear rates. This technique eliminates medial and lateral knot impingement. Concerning the potential reduction in the medial strangulation of the tendon, there is a need for further clinical research.

Abstract

BACKGROUND:Acromioplasty is commonly performed during arthroscopic rotator cuff repair, but its effect on short-term outcomes is debated. 

PURPOSE:To report the short-term clinical outcomes of patients undergoing arthroscopic repair of full-thickness rotator cuff tears with and without acromioplasty. 

STUDY DESIGN:Randomized controlled trial; Level of evidence, 2. 

METHODS:Patients undergoing arthroscopic repair of full-thickness rotator cuff tears were randomized into acromioplasty or nonacromioplasty groups. The Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES) score, Constant score, University of California-Los Angeles (UCLA) score, and Short Form-12 (SF-12) health assessment were collected along with physical examination including range of motion and dynamometer strength testing. Intraoperative data including tear size, repair configuration, and concomitant procedures were recorded. Follow-up examination was performed at regular intervals up to 2 years. Preoperative imaging was reviewed to classify the acromial morphologic type, acromial angle, and lateral acromial angulation. 

RESULTS:A total of 114 patients were initially enrolled in the study, and 95 (83%; 43 nonacromioplasty, 52 acromioplasty) were available for a minimum 2-year follow-up. There were no significant differences in baseline characteristics, including number of tendons torn, repair configuration, concomitant procedures, and acromion type and angles. Within groups, there was a significant (P < .001) improvement in all functional outcome scores from preoperatively to all follow-up time points, including 2 years, for the nonacromioplasty and acromioplasty groups (ASES score: 55.1-91.5, 48.8-89.0; Constant score: 48.3-75.0, 51.9-78.7, respectively). There were no significant differences in functional outcomes between nonacromioplasty and acromioplasty groups or between subjects with different acromial features at any time point. 

CONCLUSION:The results of this study demonstrate no difference in clinical outcomes after rotator cuff repair with or without acromioplasty at 2 years postoperatively.

Effect of Immobilization without Passive Exercise After Rotator Cuff Repair Randomized Clinical Trial Comparing Four and Eight Weeks of Immobilization

Koh K, Lim T, Shon M, et al.

J Bone Joint Surg Am, 2014 Mar 19;96(6):e44 1-9.

Background:

While animal studies have shown better healing with a longer duration of protection without motion exercise after rotator cuff repair, supporting clinical studies are rare. The purpose of this study was to assess the effect of immobilization following rotator cuff repair and to determine whether there was any difference in clinical outcome related to the duration of immobilization.

Methods:

One hundred patients who underwent arthroscopic single-row repair of a posterosuperior rotator cuff tear (mean, 2.3 cm in the coronal-oblique plane and 2.0 cm in the sagittal-oblique plane) were prospectively randomized to be treated with immobilization for four or eight weeks. During the immobilization period, no passive or active range-of-motion exercise, including pendulum exercise, was allowed. According to the intention-to-treat protocol and full analysis set, eighty-eight patients were evaluated clinically and with magnetic resonance imaging postoperatively, after exclusion of twelve patients without postoperative clinical evaluation. Ranges of motion, clinical scores, and retear rates were compared between the four and eight-week groups. Ninety-eight patients were contacted by telephone at a mean of thirty-five months to investigate the clinical outcomes.

Results:

The mean duration of immobilization was 4.1 weeks in the four-week group and 7.3 weeks in the eight-week group. There were nine full-thickness retears (10%), and 89% of the patients rated their result as excellent or good. There were five full-thickness retears in the four-week group and four in the eight-week group (p = 0.726). At the time of final follow-up, the two groups showed no differences in range of motion or clinical scores. However, the proportion showing stiffness was higher in the eight-week group (38% compared with 18%, p = 0.038).

Conclusions:

Eight weeks of immobilization did not yield a higher rate of healing of medium-sized rotator cuff tears compared with four weeks of immobilization.
