The Oblique Mattress Lasso-Loop Stitch for Arthroscopic Capsulolabral Repair.

ABSTRACT: Arthroscopic capsulolabral repair during shoulder stabilization surgery requires the use of suture anchors. Several arthroscopic suturing techniques for capsulolabral repair have been described, and each carries very specific advantages and disadvantages with regard to risk, patient satisfaction, and functional outcomes. The purpose of this report is to describe the oblique mattress lasso-loop stitch. This stitch (1) provides strong initial fixation of the labrum, (2) establishes labral height and allows for larger capsular plication if needed, (3) prevents the suture from cutting through the radial fibers of the glenoid labrum, (4) prevents knot migration to the articular side and loosening of the knot, and (5) requires fewer implants and preserves glenoid bone stock by increasing the amount of labrum and capsule that can be reattached to the glenoid with a single-loaded suture anchor.

Project description:Proper placement of suture anchors is an important step in Bankart repair as improper placement can lead to failure. Concern surrounding suture anchor placement inspired the use navigation systems in shoulder arthroscopy. We aimed to demonstrate the technological advantage of using the O-arm (Medtronic Navigation, Denver, CO, USA) image guidance system to provide real-time images during portal and anchor placements in shoulder arthroscopy. Consecutive patients (from July to October 2014) who were admitted for arthroscopic capsulolabral repair surgeries were included. Ten patients were randomly enrolled in the navigation group and 10 in the traditional group. The glenoid was divided into four zones, and the penetration rates in each zone were compared between the two groups. In zone III, the most inferior region of the glenoid, the penetration rate was 40.9% in the traditional group and 15.7% in the navigation group (P = 0.077), demonstrating a trend toward improved accuracy of anchor placement with the aid of the navigation system; however, this was not statistically significant. Average surgical time in the navigation and traditional groups was 177.6±40.2 and 117.7±17.6 mins, respectively. American Shoulder and Elbow Surgeons Shoulder Scores showed no difference before and 6 months after surgery. This pilot study showed a trend toward decreased penetration rate in O-arm-navigated capsulolabral repair surgeries and decreased risks of implant misplacement; however, possibly due to the small sample size, the difference was not statistically significant. Further large-scale studies are needed to confirm the possible benefit of the navigation system. Even with the use of navigation systems, there were still some penetrations in zone III of the glenoid. This penetration may be attributed to the micro-motion of the acromioclavicular joint. Although the navigation group showed a significant increase in surgical time, with improvements in instrument design, O-arm-navigated arthroscopy will gain popularity in clinical practice.
