The purpose of our study was to evaluate the initial fixation strength of bridging techniques compared to other suture techniques for rotator cuff repair using a biomechanical animal model, which incorporated pretesting of intact tendons. The use of locked suture configurations for arthroscopic rotator cuff repairs may enhance tendon fixation and limit gap formation in the early postoperative period. The locked mattress suturing technique (group 3) provided the most secure tendon fixation of all arthroscopic configurations tested. Both locked configurations (groups 3 and 4) were superior to traditional simple and horizontal mattress configurations in resisting 10-mm gap formation. 0001), requiring a mean of 628 cycles in comparison to 65, 193, and 197 cycles for groups 1, 2, and 4, respectively.
The locked mattress configuration (group 3) outperformed all other groups in resisting 5-mm gap formation (P <. The number of cycles required to form gaps of 5 mm and 10 mm was recorded. A cyclic loading protocol with application of forces from 10 to 180 N for a maximum of 2,500 cycles was used.
2 Fiberwire suture was used for the repairs. A metal corkscrew suture anchor doubly loaded with No. Four arthroscopic suture configurations were tested (8 specimens in each group): simple (group 1), horizontal mattress (group 2), locked mattress (group 3), and locked inverted mattress (group 4). To compare traditional arthroscopic suture configurations to locked arthroscopic configurations in ability to resist gap formation under cyclic loading.Ĭrescent-shaped defects were created at the infraspinatus tendon insertion in 32 bovine shoulders. "Locked" suture configurations, which use a combination of simple and transverse suture loops, have demonstrated better fixation strength than have traditional simple and horizontal mattress techniques. The optimal suture configuration for arthroscopic rotator cuff repairs is controversial.
