[Arthroscopic suturing of the rotator cuff. Placing of anchor, suturing and tying techniques].

: Arthroscopic reconstruction of a rotator cuff tear is a demanding technique. Besides assessment and appraisal of the different types of tears, their mobilisation and, especially, secure refixation of the soft tissue are necessary if the operation is to be successful: suture anchors must be optimally placed, and suturing must be reliably achieved while the surgical field is viewed arthroscopically. A correct technique for arthroscopic knot tying after passage of the suture thread through the tendon is also essential for the holding strength of the sutures. The way the suture thread is tied during the arthroscopic procedure needs to be tailored to the individual situation. It is essential that the operator has mastered the technique of tying nonslipping knots, by alternating holding and connecting threads with the use of a knot-pusher. There is a vast number of published arthroscopic knots, and the one selected as suitable also needs to be adapted to the suture material.
