  Purpose
  • The purpose of this study is to compare the clinical and anatomical outcomes of rotator cuff repair with Platelet-Rich Plasma(PRP) and conventional rotator cuff repair in treatment of large to massive rotator cuff tears.
  • PRP application to arthroscopic rotator cuff repair would accelerate recovery after arthroscopic rotator cuff repair in terms of pain relief, functional outcomes, overall satisfaction, and enhance structural integrity of repaired tendon.

Primary Outcome Measures:
  • structural integrity of repaired rotator cuff tendon [ Time Frame: postoperative 9months ]

    To evaluate structural outcomes, magnetic resonance(MR)imaging or computed tomography arthrography were used at minimum postoperative 9months.

    The structural integrity was evaluated using Sugaya's method;

    • type I, sufficient thickness with homogenously low intensity
    • type II, insufficient thickness partial high intensity
    • type III, insufficient thickness without discontinuity (thinned cuff)
    • type IV, presence of minor discontinuity
    • type V, presence of a major discontinuity

    Type I, II, and III were considered as healed, while type IV, and V were considered as retear.

Arms Assigned Interventions
Placebo Comparator: Conventional group Procedure: Conventional arthroscopic rotator cuff repair
  • Under general anesthesia, the patient was placed in the lazy lateral decubitus position on the operating table.
  • The surgical area was prepared and draped with Betadine.
  • Small stab incisions were made in the creation of 4-5 portals as needed.
  • A scope was explored via the arthroscopic portal into the GH joint & subacromial space.
  • Repair of full thickness rotator cuff tear was done with suture anchors.
  • The skin was closed with Nylon or medical staples.
  • Sterile dressing was applied on surgical wound.
Experimental: PRP group Procedure: Arthroscopic rotator cuff repair with PRP
  • Under general anesthesia, the patient was placed in the lazy lateral decubitus position on the operating table.
  • The surgical area was prepared and draped with Betadine.
  • Small stab incisions were made in the creation of 4-5 portals as needed.
  • A scope was explored via the arthroscopic portal into the GH joint & subacromial space.
  • Repair of full thickness rotator cuff tear was done with suture anchors.
  • After tying sutures of the medial row, PRP gels were applied on the repair site.
  • The lateral row was secured using suture anchors.
  • The skin was closed with Nylon or medical staples.
  • Sterile dressing was applied on surgical wound.
