Rotator Cuff Tears
Updated: Jan 27 2017

Small-to-medium full-thickness rotator cuff repair - Arthroscopic

Preoperative Patient Care
Operative Techniques

Preoperative Plan


Radiographic templating

  • identify Pathology on AP Radiographs


Execute surgical walkthrough

  • describe steps of the procedure verbally to the attending prior to the start of the case
  • describe potential complications and steps to avoid them

Room Preparation


Make sure tower working

  • 30° arthroscope
  • fluid pump system
  • standard arthroscopic instruments
  • suture passing devices
  • suture retrieving devices
  • knot tying devices
  • arthroscopic shavers and burrs
  • radiofrequency ablation wand
  • suture anchors


Room setup and Equipment

  • beach chair or statndard OR table for lateral decubitus position


Patient Positioning

  • Place on beach chair or lateral decubitus position
  • pad any prominences of the extremities
  • position the head and neck in neutral alignment
  • ensure the entire scapula is free from the edge of the table place the arm
  • place arm in articulated hydraulic arm holder

Scope Insertion


Outline landmarks

  • outline the acromion, distal clavicle, coracoid process and portal placement


Place posterior portal

  • mark portal 1 to 3 cm distal and 1 to 2 cm medial to the posterior lateral tip of the acromion
  • make small skin incision
  • place blunt trocar with the arm in 15° of abduction and 30° of forward flexion
  • use lateral traction to avoid damage to the articular surface
  • place the 30° arthroscope


Place anterior portal

  • halfway between acromioclavicular joint and the lateral aspect of the coracoid
  • pierce the anterior fibers of the deltoid and enter the joint in the interval between the supraspinatus and subscapularis


Place lateral portal

  • place laterally in line with the mid clavicle and 2 to 3 cm lateral to its lateral edge


Place posterorlateral portal

  • 1 cm distal to the posterolateral corner of the acromium


Place Nevias portal

  • superomedial portal bordered by the clavicle the acromioclavicular joint and the spine of the scapula

Diagnostic Arthroscopy and Intra-articular Debridement


Visualize the anatomy

  • articular cartridge of the humeral head and glenoid
  • labrum
  • biceps tendon
  • inferior recess
  • articular surface
  • insertion of the subscapularis, supraspinatus, infraspinatus and teres minor


Establish anterior portal

  • localize portal with an 18 gauge spinal needle placement
  • place a seven minute millimeter cannula using the outside-in technique


Debride tissues

  • place a 4.5 mm for radius shaver in anterior portal for intraarticular debridement
  • debride degenerative labral tears, synovitis and cartilage lesions

Subacromial Bursectomy +/- Acromioplasty


Move trocar

  • move the arthroscope to the subacromial space
  • slide the trocar under the acromium over the posterior rotator cuff
  • sweep under the acromium through the lateral gutter to break up adhesions


Identify the coracoacromial ligament

  • found on the anterior aspect of the subacromial space


Create a lateral working portal

  • localize portal with spinal needle through the deltoid
  • insert 8.25 mm threaded cannula into lateral portal


Perform bursectomy

  • use a 4.5 mm barrel shaped burr through the lateral portal
  • use the full radial shaver to perform a complete bursectomy
  • remove remaining bursa and soft tissue from the undersurface of the acromion with a radiofrequency ablation wand
  • examine the anterior aspect of the acromium and cc ligament for signs of impingement


Perform acromioplasty

  • partially resect the cc ligament with the ablation wand to expose the entire acromium
  • start the acromioplasty at the anterior lateral corner and remove 5 to 8 mm of bone
  • carry the resection medially to the AC joint
  • make the resection level by sweeping the burr from anterior to posterior
  • move the arthroscope to the lateral portal place and place burr in the posterior portal
  • sweep the bird from a medial to lateral direction

Cuff Mobilization, Preparation of Tendon and Tuberosity


Tendon Debridement

  • place the arthroscope in the posterolateral portal and the instruments in the lateral portal
  • debride the tendon with an arthroscopic basket resector or a full radius shaver
  • clear the remaining soft tissue with a radiofrequency ablation wand


Footprint Preparation

  • use shaver to remove soft tissue from the greater tuberosity
  • make sure to expose the cortical bone

Marginal Convergence Sutures


Pass sutures through margins of tear

  • use a sharp suture passing instrument loaded with a high tensile strength free suture through the anterior portal to penetrate the anterior leaf of the tear
  • use a second suture passing instrument from the posterior portal to penetrate the posterior leaf of the tear


Tie knot

  • pass the free suture from the anterior instrument to the posterior instrument
  • pull through the posterior portal
  • take both limbs of the suture and pass them through lateral portal to tie and complete the marginal convergence stitch
  • this is used and L reverse L and U-shaped tears to reduce the amount of strain on the tendon at the tuberosity repair and reduce the size of the tear

Anchor Placement, Suture Passage and Definitive Knots


Place anchors

  • place 2 or 3 medial anchors at the level of the anatomic neck
  • separate each anchor by 1 to 1.5 cm
  • make small stab incisions just off the lateral border of the acromion
  • place 2 or 3 medial anchors at the level of the anatomic neck


Pass sutures

  • pass sutures from the medial row of anchors through the tendon
  • start with the most anterior anchor
  • pass both strands of one suture through the anterior aspect of the tear in a horizontal mattress manner
  • pass sutures 1 cm medial to the lateral aspect of the tear
  • pass one strand of the second suture next to the most posterior strand o of the first suture
  • repeat steps for the posterior anchor of the medial row
  • pass two strands of one suture through the posterior aspect of the tear.
  • place one strand of the second suture anterior to the previously placed mattress suture and retrieve through the anterolateral portal
  • retrieve both strands of the posterior mattress stitch out of the lateral portal
  • tie arthroscopically and cut
  • tie the remaining strands that have been passed through the tendon together
  • tie oustide the shoulder through anterolateral portal
  • cut the tails and advance the knot into the shoulder
  • this is done by pulling on the opposite strands of the two sutures


Place a single lateral suture anchor

  • place anchor on the lateral aspect of the rotator cuff footprint on the greater tuberosity halfway between the medial anchors
  • retrieve one strand of one suture and pass it medial to the horizontal stitch between the anterior and posterior medial anchors
  • repeat step with second suture from lateral anchor


Tie knots

  • pull on the remaining medial sutures to tension the horizontal mattress stitch while the the lateral row sutures are tied
  • retrieve the remaining two strands of the medial row anchors out of the lateral portal and tie

Wound Closure, Confirm Repair and Address Intraoperative Complications


Irrigation, hemostasis, and drain

  • irrigate the portals


Deep closure

  • use 3-0 biosyn for closure


Superficial closure

  • use 4-0 biosyn for skin


Dressing and immediate immobilization

  • place sling
