"Penanganan cedera Anterior Cruciate Ligament (ACL) berupa operasi rekonstruksidengan mengambil graft tendon pada tubuh pasien sendiri sebagai pengganti ACL.Peroneus Longus Tendon graft merupakan alternatif graft untuk meminimalisirkomplikasi yang berkaitan dengan penggunaan graft dari area sekitar lutut.Peroneus Longus tendon graft dikatakan memiliki komplikasi pada donor siteantara lain instabilitas ankle serta menurunnya kekuatan fleksi 1st ray dan eversiankle. Penelitian ini mencari perbedaan terkait dengan komplikasi donor sitedengan membandingkan tehnik pengambilan graft dengan dan tanpa penjahitanpada distal stump Peroneus Longus tendon terhadap peroneus brevis tendon.Penelitian ini adalah studi yang mencari hubungan antar variabel dengan desainrandomized controlled trial untuk mengetahui luaran fungsional secara subyektifdan obyektif. Rata-rata usia subyek adalah 26.08 ± 2.4 tahun. Dari 13 subjek, 11laki-laki dan 2 perempuan. Pada kelompok penjahitan didapatkan rerata deltakekuatan otot pre operasi terhadap 6 bulan pasca operasi 0.88±0.22 kg, sedangkanpada kelompok tanpa penjahitan adalah 0.67 (0.33-6) kg. Pada kelompok denganpenjahitan didapatkan rerata Clarke’s angle pasca operasi 6 bulan 39.67± 1.28derajat dan pada kelompok tanpa penjahitan distal stump adalah 39.5± 1.50 derajat.Pada pengukuran subyektif The American Orthopedic Foot and Ankle Score(AOFAS), dan visual analogue scale foot and ankle (VAS-FA), kelompok denganpenjahitan lebih superior daripada tanpa penjahitan dalam hal kenyamanan pasien.Pengambilan graft peroneus longus baik dengan dan tanpa penjahitan distal stumptidak menurunkan kekuatan otot plantarfleksi dan tidak menyebabkan perubahanbentuk arch kaki. Penjahitan distal stump saat pengambilan graft peroneus longusmengurangi kemungkinan komplikasi nyeri baik pada 3 bulan dan 6 bulan pascaoperasi.......Anterior Cruciate Ligament (ACL) rupture treatment is a reconstructive surgery bytaking a tendon graft on the patient's own body as a substitute for ACL. PeroneusLongus Tendon graft is an alternative graft to minimize complications related tothe use of graft from the area around the knee. Peroneus Longus tendon graft issaid to have complications at donor sites including ankle instability and decreasedflexion strength of 1st ray and ankle eversion. This study looked for differencesrelated to donor site complications by comparing graft harvest techniques with andwithout suturing of the Peroneus Longus tendon distal stump to the peroneus brevistendon. This study is a study that looks for relationships between variables withrandomized controlled trial designs to find out functional outcomes subjectivelyand objectively. The mean age of the subjects was 26.08 ± 2.4 years. Of the 13subjects, 11 were male and 2 were female. In the suturing group, the mean preoperativedelta muscle strength of 6 months postoperatively was 0.88 ± 0.22 kg,whereas in the group without suturing it was 0.67 (0.33-6) kg. In the group withsuturing, the mean Clarke’s angle postoperatively was obtained 6 months 39.67 ±1.28 degrees and in the group without distal stump suturing was 39.5 ± 1.50degrees. In the subjective measurements of The American Orthopedic Foot andAnkle Score (AOFAS), and visual analogue scale foot and ankle (VAS-FA), groupwith suturing are superior to those without suturing in terms of patient comfort.Peroneus longus graft harvesting both with and without distal stump suturing doesnot decrease plantarflexion muscle strength and does not cause changes in footarch. Distal stump suturing reduces the"

"This textbook examines the short- and long-term impacts of ACL injuries on the basis of hundreds of published studies. Risk factors for such injuries are explored using data from hypothesis-driven investigations, and possible causes of the higher risk of noncontact ACL injuries in female athletes are analyzed. Neuromuscular training programs shown to reduce the rate of these injuries in female athletes are described in step-by-step detail with the aid of numerous color photographs and video demonstrations. In addition, detailed descriptions are provided for rehabilitation programs to be used after ACL reconstruction in order to reduce the risk of a future injury."

"Cedera pada Anterior Cruciate Ligament (ACL) sering terjadi pada atlet yang berpartisipasi dalam olahraga intensitas tinggi. Namun, kerusakan ACL juga bisa terjadi pada masyarakat umum. Fatigue dijelaskan oleh perubahan protein struktural utama, heliks kolagen tipe 1. Hal ini merusak ligamen dan menyebabkan kelemahan pada jaringan. Delapan puluh persen kerusakan ACL dilaporkan sebagai kerusakan tanpa kontak langsung, yang bertentangan dengan gagasan bahwa kerusakan ACL terjadi dalam kasus kelebihan beban. Chen dkk. menunjukkan bahwa tanda-tanda fatigue seperti rongga struktural, kekuatan tarik yang lebih rendah dan perubahan komposisi kimia dari heliks kolagen normal menjadi untaian terdenaturasi (1740cm-1) dapat mengurangi integritas struktural ACL yang pada akhirnya menyebabkan kegagalan dini. Penelitian ini membutuhkan lebih banyak detail dalam tanda-tanda baru yang dapat menyebabkan kerusakan ACL akibat fatigue. Proyek ini menganalisis topografi, komposisi kimia, mekanika jaringan seperti kekakuan, dan perubahan sinyal autofluoresensi menggunakan Atomic Force Microscopy Infrared Spectroscopy (AFM-IR) dan endoskopi konfokal. Hasil penelitian menunjukkan bahwa hubungan antara kekakuan dan kerusakan akibat kelelahan adalah semakin tinggi proporsi kolagen gangguan, semakin rendah frekuensi PLL dan semakin rendah kekakuan material. Efek kerusakan mekanis juga ditunjukkan pada salah satu fitur topografi, D-spacing. Peningkatan D-spacing dapat disebabkan oleh deformasi plastik fibril kolagen.......Injuries to the Anterior Cruciate Ligament (ACL) are prevalent in athletes who participate in high-intensity sports. However, ACL damage can also occur in the general public. Fatigue is explained by changes in the major structural protein, the type 1 collagen helix. This destroys the ligaments and causes weakness. Eighty percent of ACL damage is reported to be non-contact damage, which contradicts the notion that failure occurs in the case of a single overload. Chen et al. showed that fatigue signatures such as structural voids, lower tensile strength and change in chemical composition from normal collagen helices to denatured strands (1740cm-1) could reduce the structural integrity of the ACL ultimately leading to early failure. However, the study needs more detail in these novel signatures of fatigue damage. This project analyses topography, chemical composition, tissue mechanics such as stiffness, and changes in autofluorescence signal using Atomic Force Microscopy Infrared Spectroscopy (AFM-IR) and confocal endoscopy. Other techniques can be explored for the future but are not the focus of this project. The results show that the relationship between stiffness and fatigue damage is that the higher the proportion of disorder collagen, the lower the PLL frequency and the lower the material's stiffness. The effect of mechanical damage is also shown on one of the most critical topographical features, D-spacing. The increase in D-spacing may be due to the plastic deformation of collagen fibrils."
