Primary Outcome Measures:
  • Operation-Success [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Technical success confirmed at the end of surgery and no dislodge/broken anchor nor ruptured sutures observed at 12 weeks post operative evaluation. MRI results will be evaluated by an independent evaluation committee.

  • Clinical Function [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    JSS-SIS (Japan Shoulder Society Shoulder Instability Score) and Rowe score at 12 weeks after surgery will be observed. Both scores will be evaluated by other surgeon who did not operate the surgery.

Secondary Outcome Measures:
  • Procedure success [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Insertion of anchor in Fossa articularis without breaking and suture without pulling off from the tissue during surgery.

  • Clinical Function [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    JSS-SIS and Rowe score at 24 weeks after surgery will be observed.

  • Laboratory Test evaluation [ Time Frame: 12 weeks and 24 weeks ] [ Designated as safety issue: Yes ]
    Abnormal laboratory test data considered to be related to the study device or procedure at 12 weeks and 24 weeks.

  • Adverse Events [ Time Frame: From day of IC to 24 weeks ] [ Designated as safety issue: Yes ]
    Adverse events observed by 24 weeks after surgery.
