Outcome of arthroscopic rotator cuff repair in large tears: the exposed footprint.

The purpose of this retrospective study was to evaluate the clinical results of arthroscopic single-row repair in large rotator cuff tears. Selection was based on the extent of the "exposed footprint" (EFP) obtained by adding up the width of the subscapularis tear and the width of the supra/infraspinatus tear. Three groups were studied: Type I had an EFP of less than 5 cm; Type II had an EFP of 5 cm or more; tears allowing only partial repair were studied separately.

A comparative clinical evaluation of arthroscopic single-row versus double-row supraspinatus tendon repair.

Cadaveric studies and commercial pressure have initiated a strong trend towards double-row repair in arthroscopic cuff surgery. The objective of this study was to evaluate if the biomechanical advantages of a double-row supraspinatus tendon repair would result in superior clinical outcome and higher abduction strength. A retrospective study of two groups of 32 single-row and 33 double-row repairs of small to medium cuff tears was performed.
