Introduction: Rotator cuff tear with delamination is considered a risk factor for postoperative retear. The purpose of this study was to compare clinical outcomes between three repair procedures for large or massive rotator cuff tears with delamination: conventional en masse suture bridge (EMSB), double-layer suture bridge (DLSB), and the combination of DLSB with modified Debyere-Patte (DLSB + DP). Methods: 53 shoulders of 52 patients who had massive rotator cuff tears with delamination were categorized into three groups: EMSB (18 shoulders), DLSB (24 shoulders), and DLSB + DP (11 shoulders). The mean postoperative follow-up period was 34.6 months. Pre- and postoperative evaluations included a range of motion (ROM), Constant scores, global fatty degeneration (GFDI), and tendon integrity according to Sugaya’s classification by magnetic resonance images (MRI). Results: In all groups, ROM significantly improved after the procedures. Mean constant scores significantly improved: from 45.5 to 77.4 after EMSB, from 45.5 to 87.6 after DLSB, and from 46.3 to 88.0 after DLSB + DP. Significant differences were noted in postoperative Constant scores (p = 0.018: DLSB vs. EMSB, and p = 0.045: DLSB + DP vs. EMSB). The Constant pain scores were better for DLSB + DP than for EMSB (p = 0.012). Global fatty degeneration index (GFDI) with DLSB + DP was significantly higher than that for either EMSB or DLSB, indicating significant preoperative fatty degeneration for DLSB + DP. Retear occurred in 27.8% of the EMSB group, 12.5% of the DLSB group, and 9.1% of the DLSB + DP group. Discussion: Comparisons of the three groups demonstrated that DLSB and DLSB + DP achieved better clinical outcomes than EMSB for the repair of large or massive rotator cuff tears. DLSB + DP is useful for massive rotator cuff tears with severe fatty degeneration or for cases where the presence of excessive tension is anticipated when repairing the torn cuff.
Recurrent hemarthrosis after total knee arthroplasty is a rare complication. This usually occurs in osteoarthritis, but is relatively rare in rheumatoid arthritis. This is a report of recurrent hemarthrosis after total knee arthroplasty in a rheumatoid arthritis patient. An 85-year-old woman with rheumatoid arthritis had received total knee arthroplasty without acute complications. At 6 months after surgery, the first hemarthrosis occurred and an initial conservative treatment failed. Contrast computed tomography showed prominent synovial enhancement in the superior lateral suprapatellar pouch. Selective catheterization revealed an abnormal hyperemic blush supplied from the branches of the superior lateral genicular artery. After embolization with N-butyl-2-cyanoacrylate, abnormal staining of the synovium diminished and knee swelling and pain disappeared without complications. Selective embolization is favorable for successful treatment of recurrent hemarthrosis after total knee arthroplasty in patients with rheumatoid arthritis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
