    　View Summary

    BACKGROUND: Although both the classical inside-out and all-inside techniques are performed for the repair of complete radial tears, which should be the standard technique is, to the authors' knowledge, controversial considering the clinical outcomes and biomechanical studies. There are no biomechanical studies of repairs of the lateral meniscus (LM) evaluating the peripheral side gap (peripheral gap) of the radial tear site and extrusion of the LM, which seems to be important in the treatment of radial tears. PURPOSE: To compare the inside-out and all-inside meniscal repair techniques by evaluating the peripheral gap and extrusion of the LM with complete radial tear using a 6 degrees of freedom robotic system and fresh-frozen cadavers. STUDY DESIGN: Controlled laboratory study. METHODS: This study was performed using 6 fresh-frozen cadaveric knee specimens, a robotic testing system, and ultrasound evaluation. Ultrasound evaluations were performed to measure peripheral gaps and extrusions. The first ultrasound evaluation under 5 N·m of valgus load was performed on the knee at 30° and 90° of flexion. After a complete radial tear at the midsegment of the LM was created, a second ultrasound evaluation under valgus load was performed. Finally, all-inside and inside-out meniscal repairs done with 1 horizontal suture were performed on the same knee in a randomized order. Subsequently, the third and fourth ultrasound evaluations under valgus load were performed. RESULTS: The peripheral gap of the inside-out meniscal repair technique was significantly smaller than that of all-inside meniscal repairs at knee flexion angles of 30° and 90° (6.0 vs 11.5 mm and 5.6 vs 10.9 mm [both P < .0167], respectively). The extrusion of inside-out meniscal repair was significantly smaller than that of all-inside meniscal repair at a knee flexion angle of 90° (2.6 vs 3.2 mm; P < .0083). CONCLUSION: The inside-out meniscal repair technique showed less peripheral gap and extrusion of the LM in a complete radial tear than the all-inside meniscal repair. Inside-out repair may be advantageous for radial tears over all-inside repair because only inside-out repair can tighten the peripheral side of the radial tear. CLINICAL RELEVANCE: The LM with a complete radial tear should be repaired using the inside-out technique.

    ＜文献概要＞本研究は初回片側人工膝関節全置換術を施行した患者の術後鎮痛法についての比較研究である。関節周囲多剤カクテル注射(MCPI)単独群37例37膝と,MCPIと大腿神経ブロック(FNB)併用群19例19膝を対象として,術後鎮痛効果,術後メトクロプラミドの使用の有無,入退室と麻酔に要した時間について比較検討した。なお両群ともに術前からセレコキシブとトラマドール/アセトアミノフェン配合錠を内服した。結果は両群間で術後鎮痛効果,術後メトクロプラミド使用の有無に差はなかった。入退室と麻酔に要した時間は併用群で平均17.3分長かった。MCPIの鎮痛範囲が広いことや,先取り鎮痛の併用によりMCPI単独で良好な鎮痛が得られ,かつ入退室時間を短縮することが示された。

    　View Summary

    Synovial tissue was collected from RA patient group, control group (knee ligament injury etc.), and immunohistological examination was conducted. Accumulation of phosphorylated platelet-derived growth factor receptor-αβ (pPDGFRαβ) positive FLS was observed in the synovial membrane of RA. Furthermore, the expression of Bcl-2 of apoptosis-resistant marker was elevated in pPDGFRαβ positive cells, p16 of cyclin-dependent kinase inhibitor was decreased. In RA synovium, it suggested that cell proliferation cannot be stopped, apoptosis is inhibited and cells might accumulate without apoptosis.
