Background: Massive tear of rotator cuff is very difficult to care for and postoperative results are not always good. So, we perform semitendinous tendon and gracilis tendon graft for massive rotator cuff tear (ST • G graft). Our new changes are to make enough area of foot-print, to use suture bridge technique and to make tight control of ADL.
Methods: From 2009 to 2011, we performed ST • G graft on 30 cases (31 shoulders), and all cases were followed over 6 months and had postoperative MRI taken. Re-rupture of rotator cuff was decided, when someone's postoperative MRI was classified to type 4 or 5 according to Sugaya's classification. We studied ROM of shoulder, shoulder score of Japanese Orthopaedic Society, Quick DASH, right or left side, percentage of male and age. We used t-test and chi-test to compare statistically.
Results: There are 6 cases of Sugaya's type1, 16 cases of type2, 3 cases of type3, 2 cases of type4, and 4 cases of type5. Re-rupture rate of rotator cuff is 19.4%. It is a better results compared to our past series of ST • G graft for massive rotator cuff tear, that included 25% of re-rupture. Five of 6 cases, who were diagnosed as patients of re-rupture of rotator cuff were male and all 6 cases were right side.
Conclusion: New technical changes of ST • G graft for massive rotator cuff tear can improve occurrence of postoperative re-rupture, although right side tear and being male are its risk factors.
