After each portal was established, 5\u2010mm cannulas were inserted followed by guidewire\u2010assisted placement of implant fixation instruments. Each shoulder was then dissected to assess the relation of the instruments to the surrounding anatomic structures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>When the AL portal was used, instrumentation consistently passed through the rotator interval. When the N and RL portals were used, instrumentation penetrated the rotator cuff muscle belly at a mean distance of 25.75 and 7.67 mm, respectively, from the tendon. The mean angles of entry into the glenoid rim with respect to the glenoid articular surface were 32\u00b0, 38\u00b0, and \u22126\u00b0 for the AL, RL, and N portals, respectively. There was no violation of subchondral bone; however, 2 specimens showed weakened articular surfaces with use of the N portal. The RL portal was the only portal that allowed placement of instrumentation into all 3 zones of the superior glenoid rim (anterior superior, direct superior, and posterior superior) without violation of the subchondral bone and at the recommended 30\u00b0 to 45\u00b0 angle of entry.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The RL portal provides a safe and efficient method of arthroscopic fixation and knot tying of anterior and posterior SLAP lesions by use of a single instrumentation portal.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Relevance<\/jats:title>\n                    <jats:p>This novel, lateral transmuscular portal allows optimal angles of implant placement in all areas of the superior glenoid and provides a direct, simplified approach for arthroscopic knot tying.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1016\/j.arthro.2009.07.004","type":"journal-article","created":{"date-parts":[[2009,11,27]],"date-time":"2009-11-27T21:40:47Z","timestamp":1259358047000},"page":"12-18","update-policy":"https:\/\/doi.org\/10.1016\/elsevier_cm_policy","source":"Crossref","is-referenced-by-count":8,"title":["A Cadaveric Analysis of the Arthroscopic Fixation of Anterior and Posterior SLAP Lesions Through a Novel Lateral Transmuscular Portal"],"prefix":"10.1002","volume":"26","author":[{"given":"Michael G.","family":"Ciccotti","sequence":"first","affiliation":[{"name":"Division of Sports Medicine Department of Orthopaedic Surgery Rothman Institute\/Thomas Jefferson University Hospital Philadelphia Pennsylvania U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"II","given":"John A.","family":"Kuri","sequence":"additional","affiliation":[{"name":"Division of Sports Medicine Department of Orthopaedic Surgery Rothman Institute\/Thomas Jefferson University Hospital Philadelphia Pennsylvania U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.
