T2-weighted MRI of the left shoulder. (a) Axial view and (b) coronal view showing suture anchor located in the acromioclavicular joint (white arrow); (c) coronal view showing the suture anchor attached to the tendon stump of a retear of the rotator cuff (white arrow).

A small amount of fluid and a suture anchor were localized intra-articularly in the ACJ (Figures 1(a) and 1(b)). Discrete LHB tendinopathy was noted in its intra-articular portion (Figures 1(b) and 1(c)).
Arthroscopic images confirmed the MRI findings. (a) View through the posterior portal: it is able to see the bioabsorbable anchor in the ACJ (white arrow). We used a spinal needle inserted through the skin superiorly through the ACJ joint, to push the anchor down ((b) white arrow) and retrieve it from the lateral working portal. (c) The retear of the rotator cuff was repaired with double row technique (d) using 2 medial and 1 lateral bioabsorbable anchors.

ACJ was not overt because of fibrous tissue covering the implant. After removing the soft tissue with a shaver, the bioabsorbable anchor was exposed inside the ACJ joint (Figure 2(a)). This needle pushed the anchor downward and the surgeon was able to remove it (Figure 2(b)). The second anchor was visible, attached to the tendon stump, and a large retear of the RC was seen (Figure 2(c)). We removed the anchor from the tendon and performed a new double row repair with bioabsorbable anchors and LHB tenodesis with bioabsorbable interference screw (tendon repair seen in Figure 2(d)).
