Hyaluronic Acid Instillation Following Arthroscopic Anterior Cruciate Ligament Reconstruction: A Double-blinded, Randomised Controlled Study.

PURPOSE: To assess the effect of hyaluronic acid instillation after arthroscopic anterior cruciate ligament (ACL) reconstruction for improving pain, range of movement, and function of the knee. METHODS: 28 men and 4 women underwent arthroscopic ACL reconstruction for isolated ACL rupture (partial or complete) and instability after recreational sports injury 2 to 120 months earlier. They were randomised to undergo arthroscopic ACL reconstruction followed by intra-articular viscoseal instillation (13 men and 3 women) or arthroscopic ACL reconstruction alone (15 men and 1 woman). The knee injury osteoarthritis outcome score (for pain, symptoms, activities of daily living, sport and recreation function, and quality of life), range of movement, knee circumference, and analgesic use were assessed on days -1, 1, and 2, and weeks 2, 6 and 12. RESULTS: Patient demographics were similar at baseline. At postoperative days 1 and 2, all subscales of the knee injury osteoarthritis outcome score (except for quality of life) were significantly higher in the viscoseal group. At weeks 2, 6, and 12, improvement in both groups equalised. Knee swelling (change in knee circumference) was significantly less in the viscoseal group at days 1 and 2 (p=0.009 and p=0.038, respectively, Mann-Whitney U test). Only one patient in the viscoseal group had a limited range of movement. No patient developed any adverse reaction. CONCLUSION: Intra-articular viscoseal instillation improved pain control and swelling 2 days after arthroscopic ACL reconstruction.published_or_final_versio

Capacidade seladora proporcionada por alguns materiais quando utilizados em perfurações na região de furca de molares humanos extraídos Sealing capacity produced by some materials when utilized under furcation perforations of extract human molars

Avaliou-se, in vitro, a capacidade seladora, do MTA-Angelus, ProRoot-MTA, Super-EBA e MBP-c, quando utilizados para selar perfurações na região de furca de molares humanos extraídos; quando aplicados isoladamente ou em associação com uma matriz de gesso Paris, aplicada no fundo do trajeto da perfuração. O selamento produzido pelos materiais foi analisado por meio da infiltração do corante rhodamine B 0,2%. A análise estatística aplicada aos dados obtidos demonstrou que, quando utilizado isoladamente (sem matriz), o cimento MBP-c apresentou os menores índices de infiltração marginal, seguido pelo Super-EBA, apresentando diferença estatística significante (p< 0,001) entre esses e os cimentos ProRoot-MTA e MTA-Angelus. Na presença da matriz, o cimento MBP-c também foi superior, havendo diferença estatística significante (p<0,05) entre ele e os cimentos ProRoot-MTA e MTA-Angelus. A aplicação da matriz de gesso Paris influenciou negativamente a capacidade seladora dos cimentos Super-EBA e MBP-c; inclusive, com diferenciação estatística (p<0,05), contudo, ela evitou o extravasamento dos materiais seladores.<br>It has been evaluated in vitro the sealing capacity of MTA-Angelus, ProRoot-MTA, Super-EBA and MBP-c when sealing furcal perforations of extracted human molars. The experiment took place with materials both isolated as well as in association with a plaster of Paris matrix applied at the bottom of the perfuration path. The materials sealing capacity was analyzed by dye leakage of rhodamine B 0,2%.The statistical analysis revealed that when isolated and tested (without the matrix), the cement MBP-c presented the smallest coefficient of marginal leakage, followed by the Super-EBA. There was a statistical significance between those and the cements ProRoot - MTA e MTA - Angelus (p<0,001). In the presence of the matrix, the cement MBP-c also had a superior performance having statistical significance between those and the cements ProRoot - MTA e MTA - Angelus (p<0,05); The Plaster of Paris matrix had a negative impact with statistical significance regarding the sealing capacity of the cements Super-EBA and the MBP-c (p<0,05). Nevertheless, it avoided the leakage of the respective sealing materials
