Arthroscopic Rotator Cuff Repair

- Discussion: 
 
      - rotator cuff anatomy
       - etiology of RTC tears
       - how do these tears heal?
       - massive RTC
       - open rotator cuff repair
   
- Technique:
    - arthroscopy exposure and setup
            - inorder to avoid extrasavation, begin with fluid pressure at 35 mm, and increased pressures incrementally as necessary;
    - irrigation fluid management
    - visualization:
            - manipulation:
consider manipulation into full flexion and abduction prior to prepping to help stretch the posterior capsule;
            - anterolateral traction will impove the viewing area, and facilitate procedure;
            - posterior portal: consider placing this slightly more lateral to facilitate visualization;
            - consider slightly shifting porotals inferior since portals will migrate superiorly with shoulder infiltration and swelling;
            - allows better triangulation (than lateral portal) for approach to supraspinatus;

- Cuff Repair Techniques 
       - surgical goals:
              - restoration of anatomy (with no lateralization of repair and no unnecessary increase in tension of the repair);
              - any lateralization of cuff repair may cause excessive tension (increase failure) and may end up minimizing compresssion
                        against the foot print;
              - goal should be restoration of the footprint with the end of the cuff placed under compression against the bleeding footprint; 
              - suture and anchor placement should function to compress cuff against footprint, and to work to prevent cuff lateralization;
       - required steps: 
             1) assessment of cuff tear
             2) cuff mobilization (convergence repair)
             3) preparation and restoration of  the foot print
             4) core tendon repair techniques:
                     - double row and single row techniques:
                    
- core flexor tendon repair techniques: dont forget the contributions of the hand sugeons to tendon repair; 
                     - remember that the main cause of rotator cuff repair failure is when the suture pulls through the tendon;

             5) bone anchor insertion
                     - this step takes into consideration restoration of footprint and optimally making sure that tensioned cuff is draped over
                              anchor site;
             7) tensioning and locking of sutures
                       - sutures can be locked to anchor vs. knot tying tech
