Tissue fixation security in transosseous rotator cuff repairs: A mechanical comparison of simple versus mattress sutures

Biomechanical comparison of single-row arthroscopic rotator cuff repair technique versus transosseous repair technique

“…Several aspects of the methods of our study differ from earlier studies. First, prior biomechanical studies have analyzed small-and medium-sized tears of 1 to 3 cm, 5,6,8,13 whereas our study investigated larger tears. Second, no other study has directly compared massive and large tears using a biomechanical model to determine if massive tears have higher failure rates than large tears.…”

“…2,10 In addition, the functional outcome of RCR correlates with tendon healing, with better outcome noted in shoulders with intact repairs. 3 5,6 whereas others have found no significant differences. 13,34 More recent studies of newer techniques of ARCR have reported significant improvement compared with traditional ORCR techniques.…”

Does Suture Technique Affect Re-Rupture in Arthroscopic Rotator Cuff Repair? A Meta-analysis

“…In a prospective study of arthroscopic SR repairs, Ko et al 19 found higher rates of patient satisfaction and lower rerupture rates for mattress sutures compared with simple sutures. On the other hand, Burkhart et al 28 found that repairs by simple sutures were significantly stronger than repairs by mattress sutures when using transosseous fixation in cadaveric shoulders. This finding was justified by the observation that most repairs failed at the knot, and each simple suture repair contained 2 knots as opposed to the single knot used in a mattress stitch, accounting for the significant difference in load to failure.…”

Arthroscopic repair of partial-thickness tears of the rotator cuff

“…Two simple sutures per anchor were passed through the cuff. 3 Meticulous technique was used to achieve knot security. Great care was taken to ensure loop security with direct apposition between the cuff tissue and the greater tuberosity 4 (Figure 2).…”
