Contribution of postoperative ultrasound to early detection of anchor pullout after rotator cuff tendon repair: Report of 3 cases.

INTRODUCTION

Rotator cuff repair by suture bridge is now widely used. Few studies reported secondary pullout of radiotransparent anchors. The aim of the present prospective study was to demonstrate the contribution of in-office ultrasonography to detect pullout, and to describe the examination procedure.

MATERIAL AND METHOD

A total of 102 patients underwent arthroscopic rotator cuff repair by suture bridge, with impacted second-row anchors. Ultrasonography was performed by the surgeon in postoperative consultations.

RESULTS

At 6 weeks' follow-up, 3 patients showed mean 2nd-row implant pullout of 8.3mm. All underwent arthroscopic revision to extract the implant, which was mobile within its tunnel in all cases. Clinical progression was good, with mean Constant score 72 and no aggravation of the lesion on ultrasound at 3 months' follow-up.

DISCUSSION

The present series would seem to be the first to report: early radiotransparent in-vivo pullout 6 weeks after suture bridge cuff repair; ultrasound detection of pullout in consultation by the orthopedic surgeon; a description of the ultrasound technique for screening this rare and specific problem.

CONCLUSION

Ultrasound now enables radiotransparent anchor positioning to be monitored following rotator cuff repair as of the first postoperative days, without compromising tendon healing.
