  8. The changes of fatty degeneration and shoulder strengths in nonsurgically treated rotator cuff tears, Yoshihiro Nakamura, Shin Yokoya, Yohei Harada, Katsunori Shiraishi, Yu Mochizuki, Nobuo Adachi, Mitsuo Ochi, 2016 annual meeting of American Academy of Orthopaedic Surgeons, 2016/03/16, Without Invitation, English, Orlando, USA, Introduction Because rotator cuff tears are often asymptomatic, nonsurgical treatment is typically the first therapy, and if improvement is not achieved, surgical repair is considered. Although fatty degeneration of the rotator cuff muscles is predictive factor of clinical outcome after rotator cuff repair, the progression of fatty degeneration in rotator cuff tears which receive nonsurgical treatment is poorly understood. In addition, it is expected that fatty degeneration of rotator cuff muscle in rotator cuff tears have a relationship with shoulder strength. Therefore, the purpose of this study is evaluate relationship of fatty degeneration in rotator cuff muscle and shoulder strength, and these changes during nonsurgical treatment. Methods Fifty three shoulders from 47 patients (mean age 69.9 years) diagnosed with rotator cuff tears by MRI were treated nonsurgically. The degrees of fatty degeneration in supraspinatus muscle and infraspinatus muscle were graded by a modified Goutallier classification. The isometric strength of the abductors and the external rotators were examined with a hand dynamometer (MicroFET, Nihonmedix, Japan). Because strength is assumed to vary according to gender and age, we calculated the relative muscle strength of the patients compared with the normal muscle strength according to gender and age. (A pilot study had been conducted prior to the present study, in which we measured the strength of the abductors and the external rotators in 40 adult volunteers who had no shoulder pain and no rotator cuff tear in ultrasonography.) We analyzed the correlation of modified Goutallier classification in supraspinatus muscle and infraspinatus muscle with strength of the abductors and the external rotators. In addition, MRI and strength test were repeated after 24 ± 6 months and changes in fatty degeneration and strength were examined. Statistical analyses were conducted with the Pearson's product-moment correlation coefficient, the Wilcoxon signed-rank test, and the Mann-Whitney U tests. A p < 0.05 indicated statistical significance. Results Fatty degeneration of the supraspinatus had negative correlation with the strengths of abductor and external rotator (P<0.01, P<0.01). Fatty degeneration of the infraspinatus also had negative correlation with the strengths of abductor and external rotator (P<0.01, P<0.01). Eight shoulders of 45 shoulders which were Grade from 0 to 3 of the supraspinatus muscle had progression of fatty degeneration in the supraspinatus and 10 shoulders of 43 shoulders which were Grade from 0 to 3 of the infraspinatus muscle had progression of fatty degeneration in the infraspinatus. The group which had progression and the group which had no progression in fatty degeneration of the supraspinatus were compared. The both groups didn’t show improved abductor and external rotator strengths. The strengths of abductor and external rotator in the group which had progression was significantly lower than in the group which had no progression (P<0.01, P<0.05). The group which had progression and the group which had no progression in fatty degeneration of the infraspinatus were also compared. The both groups didn’t show improved abductor and external rotator strengths. The strengths of abductor and external rotator in the group which had progression was significantly lower than in the group which had no progression (P<0.01, P<0.01). Conclusions Although fatty degeneration of the rotator cuff muscles had negative correlation with the strengths, fatty degeneration in the rotator cuff muscle may progress after muscle weakness.

Outcome of Arthroscopic Rotator Cuff repair with Supraspinatus and Infraspinatus Muscle Advancement for Large-to-Massive Rotator Cuff Tears, Shin Yokoya, Yoshihiro Nakamura, Yohei Harada, Katsnori Shiraishi, Yu Mochizuki, Mitsuo Ochi, 23rd Spring Congress of Korean Shoulder and Elbow Society, 2015/05/01, Without Invitation, English, Hyung Bin Park, Jeju, Korea, Aim : We evaluated short clinical outcomes and anatomical healing rate after ARCR combined with muscle advancement. Methods : 34 patients diagnosed as large to massive RCT were included in the current retrospective study. Of these patients, 17 patients were underwent transosseous equivalent ARCR with muscle advancement (study group) and 17 were underwent transosseous equivalent ARCR only (control group). ARCR combined with muscle advancement was performed as follows; after arthroscopic suprascapular nerve release, 4 cm transverse skin incision was created along the medial border of the scapular spine for the muscle advancement. Trapezius was detached from the spine, and the SSP and ISP muscle belly was released from the scapular body. The transosseous equivalent ARCR was performed conventionally in every patients. The pre- and post-operative Constant scores were assessed for the clinical outcomes for each group. Furthermore, the cuff integrity was assessed by post-operative MRI, and each failure rate was calculated. Results : Although there was statistically significant improvement for the mean Constant score from 65.5 preoperatively to 89.0 postoperatively in the study group and from 61.1 preoperatively to 87.0 postoperatively in the control group, there was no significant difference between these two groups. And the failure rates in the study group were significantly lower than in the control group (23.5% and 52.9%, respectively). Conclusions : The ARCR with SSP and ISP muscle advancement was useful to reduce the failure rate of the ARCR for large to massive RCT in our study group.

We therefore performed ARCR with absorbable artificial biomaterial augmentation. We report the surgical techniques and clinical results. Materials and Methods: 17 patients (average age was 65.3 years old) who diagnosed as RCT and underwent ARCR with polyglycolic acid (PGA) sheet augmentation more than one year ago were included. 5 patients had degenerative tendon tissue, and 12 had too massive rotator cuff tear to cover the footprint entirely by the tendon stump even if the advancement of rotator cuff muscle was performed. We used 0.5 mm PGA sheet in the shape of double-overlapped over the tendon stump. After passed through the sheet, each suture from medial anchor held the sheet by the lateral anchor with suture bridge techniques. We evaluated the clinical outcome using Japanese Orthopaedic Association (JOA) score and cuff integrity using Sugaya classification by MRI one year after surgery. Results: We didn’t experience any inflammatory cases such as infection or foreign body reaction in the follow-up periods. JOA score was improved from 67.5 preoperatively to 88.4 postoperatively. Cuff integrity resulted in 8 of type I, 7 of type II, and 2 of type III, and there are no type IV or V suspected as re-rupture. Conclusions: ARCR with PGA sheet augmentation is useful for such degenerative or massive RCT achieving good clinical outcome, low risk of inflammation, and low failure rate.
  12. Outcome of Arthroscopic Rotator Cuff Repair with Supraspinatus and Infraspinatus Muscle Advancement for Large-to-Massive Rotator Cuff Tears, Shin Yokoya, Yoshihiro Nakamura, Yohei Harada, Katsunori Shiraishi, Yu Mochizuki, Mitsuo Ochi, 10th International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine, 2015/06/07, Without Invitation, English, Shin Yokoya, Yoshihiro Nakamura, Yohei Harada, Katsunori Shiraishi, Yu Mochizuki, Mitsuo Ochi, Lyon, France, Introduction: For small- to medium-sized rotator cuff tear (RCT), many authors report good to excellent clinical outcomes as well as high anatomical healing rates after arthroscopic rotator cuff repair (ARCR). However, high failure rates after ARCR were often reported for large to massive RCT. Since prior reports have shown a direct correlation between the postoperative clinical outcome and anatomic healing of the RCT, reduction of the failure rate after ARCR might be crucial to achieve the excellent outcome of the ARCR. We therefore performed ARCR combined with mini-open supraspinatus (SSP) and infraspinatus (ISP) muscle advancement for large to massive rotator cuff tear to decrease the tension on the repair site with the aim of reduction of the failure rate. In the current study, we evaluated the short clinical outcomes and anatomical healing rate after ARCR combined with muscle advancement. Methods: Between April 2008 and March 2012, 34 patients diagnosed as large to massive RCT were included in the current study. Of these patients, 17 patients were underwent transosseous equivalent ARCR with muscle advancement (study group) and 17 were underwent transosseous equivalent ARCR only (control group). ARCR combined with muscle advancement was performed as follows; 4 cm transverse skin incision was created along the medial border of the scapular spine for the muscle advancement. Trapezius was detached from the spine, and the SSP and ISP muscle belly was released from the scapular body. The medial fascial continuity between rhomboideus and SSP and ISP muscles were retained carefully beyond the medial border of the scapula. By this procedure, the tendon stumps can be advanced for 2 to 3 cm. The arthroscopic suprascapular nerve release was added in this procedure. The transosseous equivalent ARCR was performed conventionally in every patients. The pre- and post-operative Constant scores were assessed for the clinical outcomes for each group. Furthermore, the cuff integrity was assessed by post-operative MRI, and each failure rate was calculated. Results: Although there was statistically significant improvement for the mean Constant score from 43.4 preoperatively to 71.1 postoperatively in the study group and from 42.4 preoperatively to 78.1 postoperatively in the control group, there was no significant difference between these two groups. As the cuff integrity, the failure rates in the study group were significantly lower than in the control group (23.5% and 52.9%, respectively). There were statistically significant difference between these groups (p<0.05). Discussion and conclusion: The ARCR with SSP and ISP muscle advancement was useful to reduce the failure rate of the ARCR for large to massive rotator cuff tear in our study group. More large numbers of patients will be needed to declare the effectiveness of this technique. Arthroscopic rotator cuff repair assisted by mini-open supraspinatus and infraspinatus muscle advancement reduced the failure rate for the large to massive rotator cuff tear.
