Area of Science:

  • Orthopedic Surgery
  • Musculoskeletal Research
  • Surgical Techniques

Background:

  • Rotator cuff tears are classified into four geometric patterns: crescent, longitudinal (U- or L-shaped), massive contracted, and arthropathy.
  • Standard surgical repair for L-shaped rotator cuff tears involves identifying the apex and side-to-side suturing.

Purpose of the Study:

  • To introduce a novel and efficient surgical technique for repairing L-shaped rotator cuff tears.
  • To describe the
  • M"-shaped suturing method using specific instrumentation.

Main Methods:

  • The technique note details an "M"-shaped suturing approach.
  • It employs two suture anchors and three sutures.
  • The procedure involves four knotting steps.
