Abstract: PURPOSE: Re-establishment of the native footprint during rotator cuff repair is important for maximizing healing potential and fixation strength. 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 = 101 mm(2), 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 (0.78 MPa) was similar to that of the Mason-Allen (0.74 MPa) and double-row repairs (0.79 MPa). The ultimate tensile strength of the cruciate suture repair was significantly greater than that of the transosseous repair (mean difference 62.4 N, 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.
