Forty fresh\u2010frozen sheep shoulders were randomly assigned to five repair groups: single\u2010row repair using simple stitches (SRA\u2010s), single\u2010row repair using horizontal mattress stitches (SRA\u2010m), and single\u2010row repair using arthroscopic Mason\u2010Allen stitches (SRA\u2010ama). Double\u2010row repair was either performed with a combination of simple and horizontal mattress stitches (DRA\u2010sm) or with arthroscopic Mason\u2010Allen\/horizontal mattress stitches (DRA\u2010amam). Investigations were performed using a pressure\u2010sensitive film system. The average contact pressure and pressure pattern were measured for each group. Contact pressure was lowest in SRA\u2010m followed by SRA\u2010s. SRA\u2010ama showed highest contact pressure of all single\u2010row treatment groups (<jats:italic>P<\/jats:italic> &lt; 0.05). DRA\u2010amam presented the highest overall contact pressure (<jats:italic>P<\/jats:italic> &lt; 0.05), whereas DRA\u2010sm exerted contact pressure equal to that of SRA\u2010ama. Both double\u2010row techniques showed the most expanded pressure pattern. Average contact pressures for the more complex single\u2010 and double\u2010row techniques utilizing arthroscopic Mason\u2010Allen stitches were greater than were those of the repair techniques utilizing simple and horizontal mattress stitches. However, the contact pattern between the anchors could be increased by using the double\u2010row technique, resulting in more footprint coverage compared to patterns utilizing the single\u2010row techniques. These results support the use of the more complex arthroscopic Mason\u2010Allen stitches and may improve the environment for healing of the repaired rotator cuff tendon.<\/jats:p>","DOI":"10.1007\/s00167-009-0771-7","type":"journal-article","created":{"date-parts":[[2009,3,20]],"date-time":"2009-03-20T15:00:34Z","timestamp":1237561234000},"page":"1466-1472","source":"Crossref","is-referenced-by-count":47,"title":["Comparative
