Arthroscopic Knot Tying on a Single Suture Limb in Case of a Torn Suture

During arthroscopic knot tying, one of the suture limbs may break before completion of the knot. With a single suture limb left, it may not be possible to secure the knot against slipping, and the surgeon may be forced to use an additional anchor to obtain a secure repair. We present a tool and method that allow completion of the knot on a single suture limb. Alternatively, the method can be used to perform all-inside endoscopic or arthroscopic knot tying without removal of the instrument from the body.
