Meniscal Repair

The meniscus plays an important role in preventing osteoarthritis of the knee. Repair of a meniscal lesion should be strongly considered if the tear is peripheral and longitudinal, with concurrent anterior cruciate ligament reconstruction, and in younger patients. The probability of healing is decreased in complex or degenerative tears, central tears, and tears in unstable knees. Age or extension of the tear into the avascular area are not exclusion criteria. Numerous repair techniques are available, and suture repair seems to provide superior biomechanical stability. However, the clinical success rate does not correlate well with the mechanical strength of the repair technique. Biologic factors might be of greater importance to the success of meniscal repair than the surgical technique. Therefore, the decision on the most appropriate repair technique should not rely on biomechanical parameters alone. Contemporary all-inside repair systems have decreased the operating time and the level of surgical skill required. Despite the ease of use, there is a potential for complications because of the close proximity of vessels, nerves, and tendons, of which the surgeon should be aware. There is no clear consensus on postoperative rehabilitation. Weight bearing in extension would most likely not be crucial in typical longitudinal lesions. However, higher degrees of flexion, particularly with weight bearing, give rise to large excursions of the menisci and to shear motions, and should therefore be advised carefully. Long-term studies show a decline in success rates with time. Further studies are needed to clarify the factors relevant to the healing of the menisci. Tissue engineering techniques to enhance the healing in situ are promising but have not yet evolved to a practicable level.     

不同修复材料的牙齿修复效果比较

目的 比较三种不同修复材料的牙齿修复效果。方法 选取2020年1月-2021年11月于我院行口腔修 复的120例患者为研究对象，随机分为A组、B组、C组，每组40例。A组使用陶瓷材料进行修复，B组使用 树脂材料进行修复，C组使用金属材料进行修复，比较三组修复成功率及不良反应发生率。结果 三组修复 后6、12个月的修复成功率比较，差异无统计学意义（P＞0.05）；A组不良反应发生率为7.50%，低于B组的 40.00%与C组的22.50%，差异有统计学意义（P＜0.05）。结论 陶瓷、树脂及金属材料应用于口腔修复中的 效果均良好，但陶瓷材料在应用安全性方面更具优势，临床上可根据患者的需求与口腔状况选择合适的修 复材料。     

科学修复理念在口腔美容修复中的应用

目的 探讨口腔美容修复过程中引入科学修复理念的效果。方法 选取2021年2月-2022年12月在 本院进行口腔美容修复的80例患者作为研究对象，依据随机数字表法将其分成对照组和观察组，每组 40例。对照组以常规原则进行修复，观察组在对照组基础上引入科学修复理念，比较两组修复效 果、满意度、并发症发生情况以及复发情况。结果 观察组修复总有效率为95.00%，高于对照组的 80.00%，差异有统计学意义（P ＜0.05）；观察组修复满意度为100.00%，高于对照组的90.00%， 差异有统计学意义（P ＜0.05）；观察组并发症发生率以及复发率均低于对照组，差异有统计学意义 （P ＜0.05）。结论 科学修复理念应用于口腔美容修复中可以保证较高的修复效果，同时提升患者修复 满意度，降低并发症发生风险以及复发率，值得临床应用。     

开放手术和血管腔内技术在动脉疾病治疗中的联合应用

在动脉疾病的治疗中,越来越多的传统开放手术被新兴的血管腔内技术所取代,主要是由于血管腔内治疗具有微创性的优势。与传统外科手术相比,血管腔内治疗创伤小、并发症少、恢复快,尤其适
