Engaging needles: a simple technique for arthroscopic side-to-side rotator cuff repair.

Abstract

We present a simplified technique for the side-to-side arthroscopic rotator cuff repair. The instruments required for this technique are a 45 degrees Suture Lasso (SL; Arthrex, Naples, FL) and a 17F spinal needle (SN). With the arthroscope in the lateral portal, the SL is inserted through the posterior cannulas to grab healthy tissue at the posterior margin of the cuff. Through the anterior cannulas or through a skin puncture, the SN is inserted to catch healthy tissue at the anterior margin. Once both instruments are through the tissues, we manipulate them to make their tips converge. Because the SN diameter is small, it is very easy to engage its tip into the SL tip. Once engaged, a No. 1 PDS monofilament suture is easily passed through both instruments. When the suture comes out of the SL handle, both instruments can be pulled out, leaving the suture in place. Using a suture retriever clamp, the sutures are retrieved through a cannula for knot tying. This technique can be repeated as many times as necessary to place enough sutures in a side-to-side fashion to achieve the repair.
