The purpose of this study was to evaluate the contact area, contact pressure, stiffness and tensile strength of a new single-row cruciate suture repair and to compare these results to those of the Mason-Allen, double-row and transosseous repairs. Methods: Infraspinatus tendons from fifty-six lamb shoulders were harvested and randomly assigned to cruciate suture, Mason-Allen, double-row and transosseous repair groups. Repairs were performed over pressure-sensitive film and footprint contact area and pressure measured. Repaired tendon specimens were also loaded in uniaxial tension, and ultimate tensile strength and stiffness measured. Results: The cruciate suture repair established significantly greater footprint contact area compared to the Mason-Allen repair (mean difference=101mm2, p=0.003). The ultimate tensile strength and stiffness of the double-row repair was significantly higher than that of all other repair groups (p<0.05). The average footprint contact pressure of the cruciate suture repair (0.78MPa) was similar to that of the Mason-Allen (0.74MPa) and double-row repairs (0.79MPa). The ultimate tensile strength of the cruciate suture repair was significantly greater than that of the transosseous repair (mean difference 62.4N, p=0.002). Conclusion: The cruciate suture repair may improve strength and healing at the repaired tendon rotator cuff insertion relative to other single-row repair techniques. It may represent a faster, easier and more cost-effective alternative to double-row repairs.
