Osteoarthritis (OA) arises from imbalance of cartilage metabolism between the synthesis and degradation of type II collagen by the chondrocyte. Collagen type II degradation is characterized by increase in the biomarker of Ctelopeptide fragment of type II collagen (CTX-II), while the anabolic process of cartilage is characterized by an increase in the biosynthesis of procollagen amino terminal N-propeptide type IIA (PIIANP). Platelet derived growth factor (PDGF) with Hyaluronic Acid (HA) as a potent growth factor can be used to stimulate the higher formation of chondrocyte and PIIANP levels and lower CTX-II levels in mouse knee osteoarthritis model.

Background: Fractures contribute to a substantial proportion of the emergency department cases. Surgical procedures such as internal fixation of lower limb fractures posed a risk to develop deep vein thrombosis (DVT). The current diagnosis of DVT is still a challenge, as the current main parameter, the D-dimer, requires additional laboratory time and cost. Threrefore, an easier and faster alternative should be used in clinical decision making. Caprini score is among a simple method to assess the risk of a DVT, but validation is still needed before it can be implemented.Methods: This is an cross-sectional analytic study aimed to determine the relationship between Caprini scores and D-dimer level in patients with post-internal fixation of long bone fractures in lower extrimities at Sanglah Hospital Denpasar. Caprini scores were determined before surgery then D-dimer measurements were taken postoperatively. Statistical analysis was performed using the Pearson correlation method and ROC curve were generated to determine the cut-off point of Caprini Score equivalent of high risk DVT with the D-dimer as the predictor.Result: The average Caprini score was 9.37 (7-13). Mean preoperative D-dimer was 6.59 µg/ml (2.50-13.20 µg/ml), postoperatively 11.50 µg / ml (3.71-19.89 µg/ml) and mean delta D -Dimer 5.23 µg/ml (0.56-12.28 µg/ml). Pearson correlation test obtained a strong positive relationship (r = 0.726 and p≤0,0001). Analysis of the ROC curve to determine the cut-off point for Caprini score which equivalent to the high risk of DVT from D-dimer prediction (> 7.2 µg / ml) resulted in AUC of 0.824 (95% CI 0.669-0.979, p= 0.024) with the optimal cut-off point for Caprini score was 8.Conclusion: Caprini and D-dimer scores show a strong positive correlation.  Caprini scores can be considered to estimate the risk of DVT in post-internal fixation patients of lower extremities long bone fractures. Latar Belakang. Kejadian fraktur memiliki proporsi yang substansial dari total pasien yang datang ke unit gawat darurat rumah sakit. Prosedur operasi seperti pemasangan fiksasi internal pada fraktur ekstremitas bawah memiliki resiko untuk terjadinya trombosis vena dalam (DVT). Penegakan diagnosis DVT saat ini masih merupakan suatu tantangan salah satunya karena pemeriksaan laboratorium D-dimer membutuhkan waktu dan biaya tambahan, sehingga dibutuhkan alternatif yang lebih mudah dan cepat digunakan dalam pengambilan keputusan klinis. Skor Caprini merupakan salah satu cara untuk menilai resiko terjadinya suatu DVT, akan tetapi masih diperlukan validasi sebelum dapat diimplementasikan. Metode: Penelitian cross-sectional analitik dilakukan untuk mengetahui hubungan Skor Caprini dengan kadar D-dimer pada pasien paska operasi fiksasi internal fraktur tulang panjang ekstremitas bawah di RSUP Sanglah Denpasar. Skor Caprini ditentuakan sebelum operasi kemudian pengukuran D-dimer dilakukan paska operasi. Analisis statistik dilakukan dengan metode korelasi Pearson dan penentan titik potong risiko DVT dengan prediktor D-dimer menggunakan metode kurva ROC.Hasil: Rerata Skor Caprini adalah 9,37 dengan rentang skor 7-13. Rerata D-dimer sebelum operasi sebesar 6,59 µg/ml (2,50-13,20 µg/ml), paska operasi 11,50 µg/ml (3,71-19,89 µg/ml) dan rerata delta D-Dimer 5,23µg/ml (0,56-12,28 µg/ml). Uji korelasi Pearson diperoleh hubungan positif kuat antara Skor Caprini dengan kadar D-dimer (nilai r=0,726 dan nilai p≤0,0001). Analisis kurva ROC untuk menentukan itik potong  Skor Caprini yang setara dengan resiko tinggi terjadinya DVT dari prediksi D-dimer (>7,2 µg/ml) memperoleh Area Under Curve 0,824 (95% CI 0,669-0,979, p = 0,024) dengan titik potong optimal skor Caprini 8.Kesimpulan: Skor Caprini dan D-dimer menunjukkan korelasi positif yang kuat pada pasien paska fiksasi internal fraktur tulang panjang ekstremitas bawah. Skor Caprini dapat dipertimbangkan sebagai acuan dalam menentukan resiko terjadinya  DVT.

Osgood-Schlatter disease is a common cause of knee pain in children and adolescents, particularly in those who participate in sports. Repetitive force during athletic activities, along with changes that happen during a growth spurt, result in the development of traction apophysitis. Because of its typical presentation, the diagnosis is usually made clinically. The disorder generally resolves with skeletal maturity, and most patients respond to conservative therapy. Surgery can be considered in recalcitrant cases. Several approaches of surgical intervention have been proposed; each approach has its advantages and disadvantages.

Resumo Objetivos O objetivo deste estudo é revisar e analisar sistematicamente o desfecho funcional do procedimento de tenodese extra-articular lateral (TEL) em complemento à reconstrução do ligamento cruzado anterior (RLCA) em de estudos com alto nível de evidências. Métodos Realizamos a pesquisa bibliográfica para estudos clínicos comparando o método TEL como complemento à RCLA com a RLCA isolada. Os resultados principais foram a pontuação no Comitê Internacional de Documentação de Joelho (IKDC, na sigla em inglês), pontuação de Lysholm, e falhas no enxerto. Variáveis contínuas foram relatadas, como médias e intervalos de confiança (ICs) de 95%. Resultados Seis estudos clínicos com 1,049 pacientes foram incluídos na metanálise. O período de seguimento foi de, em média, 24 meses (intervalo de 6–63 meses). A adição do procedimento TEL à reconstrução do LCA resultou em melhor resultado funcional com base no escore IKDC (p < 0,05). A falha do enxerto foi menor no grupo RLCA mais TEL (16 dos 342 pacientes) em comparação com o grupo apenas RLCA (46 dos 341 pacientes) (p < 0,05). Conclusão Há evidências de alto nível de que o procedimento TEL como complemento à RLCA é preferível em termos de resultado funcional e falha do enxerto.
