Brief Summary:
Rotator cuff tear is one of the most common shoulder diseases and retears occure frequently after arthroscopic repair. Therefore, there is growing need of new therapy for improving structural outcome. This study evaluates the efficacy and safety of autologous fibroblasts during arthroscopic repair. The primary outcome is the retear rate after 24 weeks of arthroscopic repair with autologous fibroblasts. The secondary outcomes are functional evaluations including ROM, Constant score, ASES score and SST at 24 and 52 week.

Arm Intervention/treatment
Experimental: TPX-114
Subjects undergo arthroscopic rotator cuff repair with TPX-114.
Biological: TPX-114
Subjects will be treated with autologous fibroblasts (TPX-114) during arthroscopic surgery.

Procedure: Arthroscopic surgery
Subjects undergo conventional arthroscopic surgery for rotator cuff repair.

Placebo Comparator: Placebo
Subjects undergo arthroscopic surgery for rotator cuff repair without TPX-114.
Procedure: Arthroscopic surgery
Subjects undergo conventional arthroscopic surgery for rotator cuff repair.

Primary Outcome Measures :
  1. Retear rate [ Time Frame: 24week ]
    Retear rate assessed by independent evaluator with MRI
