Background: This new anchor has advantage of easiness to re-insert during surgery and revision surgery and of being able to be inserted in a narrower space because of small diameter.
Methods: We devided 110 cases of Arthroscopic Bankart repair into two groups. Group A is 86 cases using PLLA made anchor and PEEK made anchor. Group B is 24 cases using PEEK made anchor and polyester made anchor. The result of pull out test by 40 lb pull out strength during surgery, JSS score, ROWE score and degree of osteolysis measured by 3D CT were evaluated.
Results: The pre-operative JSS score of group A was 38 and post-operative score was 84. The score of group B was 42 and 91 respectively. The pre-operative Rowe score of group A was 12 and post-operative score was 81. The score of group B was 18 and 88 respectively. There were no statistically significant difference for JSS score, Rowe score nor degree of osteolysis between two groups. There was no pull out case under 40 lb pullout test. I received no conflict of interest.
Conclusion: The short term result of the new polyester-made anchor for arthroscopic Bankart repair can get the same clinical result when compared with PEEK or PLLA made anchor.
