"Pendahuluan: Kejadian ruptur tendon Achilles meningkat dalam beberapa dekade terakhir dengan insiden tertinggi didapatkan pada kelompok usia 30-39 tahun. Penanganan terkini untuk ruptur tendon Achilles adalah pembedahan dengan penjahitan primer, serta dapat juga secara konservatif pada kondisi-kondisi tertentu. Karena komplikasi adhesi dan gliding tendon sering terjadi pasca tindakan pembedahan, para peneliti berusaha menemukan bahan yang secara efektif mampu memperbaiki proses penyembuhan tendon. Platelet-rich plasma (PRP) dan membran amnion merupakan bahan yang dinyatakan memiliki potensi dalam memperbaiki proses penyembuhan tendon, mencegah adhesi dan gliding tendon. Namun, penelitian mengenai efek kombinasi keduanya masih belum pernah dilakukan.Metode: Model ruptur tendon Achilles dilakukan pada 24 ekor kelinci putih New Zealand yang terbagi dalam 4 kelompok perlakuan, yaitu kelompok kontrol, kelompok dengan pemberian membran amnion, kelompok dengan pemberian PRP dan kelompok dengan pemberian kombinasi membran amnion dan PRP. Evaluasi dilakukan pada 6 minggu setelah tindakan pembedahan berdasarkan penilaian terhadap pemeriksaan gliding tendon dengan USG, Tang score gambaran makroskopis adhesi tendon, grading adhesi secara makroskopis, Tang score gambaran histopatologis adhesi, grading adhesi secara histopatologis, serta Tensile strength tendon dengan uji tarik. Data yang didapatkan diuji secara statistik dengan jenis data dan jumlah kelompoknya.Hasil: Kelompok perlakuan membran amnion serta kelompok kombinasi membran amnion dan PRP memiliki perbedaan bermakna terhadap dalam hal gliding tendon secara USG, Tang score makroskopis dan histopatologis serta grading adhesi makroskopis dan histopatologis. Kelompok perlakuan PRP dan kombinasi membran amnion dan PRP menunjukkan perbedaan bermakna terhadap kelompok kontrol dalam hal nilai tensile strength test.......Background: The incidence of Achilles tendon rupture has increased in the last few decades with the highest incidence found in the 30-39 years of age group. The current treatment for Achilles tendon rupture is surgery with primary suturing, and can also be conservative under certain conditions. Because adhesion complications and gliding tendons often occur after surgery, the researchers tried to find a material that is able to effectively improve the tendon healing process. Platelet-rich plasma (PRP) and amniotic membrane are substances that have the potential to improve tendon healing processes, prevent adhesion and gliding tendons. However, research on the effects of the combination of both has never been done.Methods: The Achilles tendon rupture model was carried out in 24 New Zealand white rabbits, which were divided into 4 treatment groups, namely the control group, the group with the administration of amniotic membrane, the group with the administration of PRP and the group with the combination of amniotic membrane and PRP. The evaluation was carried out at 6 weeks after surgery based on an assessment of gliding tendon examination with ultrasound, Tang score macroscopic image of tendon adhesion, macroscopic adhesion grading, Tang score histopathological adhesion, histopathological adhesion grading, and Tensile strength tendon with the tensile test. The data obtained were tested statistically with the type of data and the number of groups.Results: Amniotic membrane treatment group and combined amniotic membrane and PRP treatment group had significant differences in terms of gliding tendon by ultrasound, macroscopic and histopathological Tang scores and macroscopic and histopathological adhesion grading. The PRP treatment group and combined amniotic membrane and PRP treatment group showed significant differences compared to the control group in terms of tensile strength test values.Conclusion: The administration of amniotic membrane can reduce the formed paratenon adhesion, however, it does not have statistical significance in influencing tendon strength. Giving Platelet-rich Plasma (PRP) does not affect the formation of paratenon adhesion statistically, but it affects the increase in tendon strength. The combination of amniotic membrane and PRP has a significant effect in reducing paratenon adhesion and increasing tendon strength."

"Tendinopati Achilles diabetes merupakan penyakit degeneratif akibat perubahan homeostasis jaringan tendon yang disebabkan oleh diabetes melitus tipe 2. Penyembuhan tendinopati Achilles diabetes sulit untuk dicapai karena terbatasnya kapasitas regenerasi tendon. Eksosom asal sel punca mesenkimal (SPM) sumsum tulang memiliki kemampuan dalam menghambat degenerasi jaringan sehingga berpotensi untuk mengatasi tendinopati Achilles diabetes. Efek eksosom SPM sumsum tulang terhadap tendon Achilles dapat diinvestigasi melalui perubahan ekspresi relatif gen a disintegrin and metalloproteinase domain 12 (ADAM12). Gen ADAM12 merupakan gen pendegradasi matriks yang terekspresi tinggi pada tendinopati Achilles diabetes. Penelitian ini bertujuan untuk mengetahui pengaruh injeksi 0,8 mL eksosom asal SPM sumsum tulang pada tendinopati Achilles tikus diabetes berdasarkan analisis histologi dan ekspresi gen ADAM12. Sebanyak 12 ekor tikus putih jantan galur Sprague Dawley dikelompokkan menjadi dua kelompok yang terdiri atas kelompok kontrol tendinopati (KK) dan kelompok eksosom (KE). Analisis histologi tendon Achilles posmortem hari ke-21 dilakukan dengan metode semikuantitatif skor Bonar dan histomorfometri kuantitatif luas area kolagen melalui pulasan Hematoksilin-Eosin, Alcian Blue, dan Masson’s Trichrome. Perubahan ekspresi gen ADAM12 diperiksa secara kuantitatif menggunakan qRT-PCR. Berdasarkan hasil penelitian, rata-rata skor Bonar KE (1,67 ± 1,282) ditemukan lebih rendah daripada KK (6,40 ± 2,195) secara signifikan (P = 0,001; P < 0,05). Analisis histomorfometri juga menunjukkan rata-rata luas area kolagen KE (85,15 ± 7,023) yang cenderung lebih tinggi dibandingkan KK (76,64 ± 9,237), tetapi tidak berbeda nyata (P = 0,103; P ≥ 0,05). Ekspresi gen ADAM12 KE mengalami perubahan sebesar 0,9 kali lipat lebih tinggi daripada KK, meskipun secara statistik tidak signifikan (P = 0,421; P ≥ 0,05). Dengan demikian, dapat disimpulkan bahwa injeksi 0,8 mL eksosom asal SPM sumsum tulang terbukti memiliki potensi dalam memicu perbaikan tendinopati Achilles diabetes pada hari ke-21.......Diabetic Achilles tendinopathy is a degenerative disease resulting from changes in tendon tissue homeostasis caused by type 2 diabetes mellitus. The cure of diabetic Achilles tendinopathy is difficult to achieve due to the limited regeneration capacity of the tendon. Exosomes from bone marrow-derived mesenchymal stem cells (MSC) can inhibit tissue degeneration so they have the potential to treat diabetic Achilles tendinopathy. The effect of exosomes from bone marrow-derived MSC on the Achilles tendon can be investigated through changes in the relative expression of a disintegrin and metalloproteinase domain 12 (ADAM12) gene. The ADAM12 gene is a matrix-degrading gene that is highly expressed in diabetic Achilles tendinopathy. This study aims to determine the effect of injection of 0.8 mL of exosomes from bone marrow-derived MSC on Achilles tendinopathy in diabetic rats based on histology analysis and ADAM12 gene expression. A total of 12 male white Sprague Dawley rats were grouped into two groups consisting of the tendinopathy control group (KK) and the exosome group (KE). Postmortem Achilles tendon histology analysis on day 21 was carried out using the semiquantitative Bonar score method and quantitative histomorphometry of collagen area using Hematoxylin-Eosin, Alcian Blue, and Masson's Trichrome staining. Changes in ADAM12 gene expression were examined quantitatively using qRT-PCR. Based on the research results, the mean score of Bonar KE (1.67 ± 1.282) was found to be significantly lower than KK (6.40 ± 2.195) (P = 0.001; P < 0.05). The histomorphometric analysis also showed that the average collagen area of KE (85.15 ± 7.023) tended to be higher than KK (76.64 ± 9.237) but was not significantly different (P = 0.103; P ≥ 0.05). ADAM12 KE gene expression changed 0.9-fold higher than KK, although it was not statistically significant (P = 0.421; P ≥ 0.05). Thus, the injection of 0.8 mL of exosomes from bone marrow-derived MSC was proven to have the potential to trigger improvement in diabetic Achilles tendinopathy on day 21."
