摘要
背景:对于全膝关节置换无法取得满意疗效的早期膝骨关节炎,胫骨高位截骨能促进受损软骨再生,缓解患者症状,是治疗膝骨关节炎的经典保膝治疗方案。目的:对胫骨高位截骨刺激膝骨关节炎软骨再生的有效性、作用机制及应用前景展开回顾与讨论,为利用胫骨高位截骨术联合软骨再生策略治疗膝骨关节炎提供理论基础。方法:计算机检索PubMed数据库、Web of Science、中国知网、万方医学数据库收录的相关文献。英文检索词为“knee osteoarthritis,high tibial osteotomy,limb alignment,chondrocytes,biomechanics,intra-articular”,中文检索词为“膝骨关节炎,胫骨高位截骨术,下肢力线,软骨细胞,生物力学,关节腔注射”,主要收集数据库中2013-2023年相关的文献,最终纳入75篇文献进行分析。结果与结论:①胫骨高位截骨纠正下肢力线能有效缓解患者的症状,延缓甚至避免全膝关节置换,是骨科阶梯化治疗的重要组成部分;②正常的力学微环境对软骨细胞的表型和功能维持是必须的,异常的力学信号可以通过初级纤毛、整合素、细胞骨架和核骨架成分等机械传感器转化为细胞内的化学信号,导致软骨基质代谢和炎症调控的紊乱;③异常应力作用后的软骨细胞在合适的应力下仍有恢复为正常表型的潜能,胫骨高位截骨术纠正力学微环境后可导致自发性软骨修复和滑膜炎症缓解;④对于尚不满足全膝关节置换的早期膝骨关节炎患者,胫骨高位截骨术联合软骨再生策略的前景值得期待。
BACKGROUND:For early knee osteoarthritis in which total knee arthroplasty fails to achieve satisfactory results,high tibial osteotomy that has been found to promote regeneration of damaged cartilage and alleviate symptoms in patients is considered a classic knee-preserving procedure.OBJECTIVE:To review and discuss the effectiveness,mechanism,and application prospects of high tibial osteotomy in stimulating cartilage regeneration in knee osteoarthritis and to provide a theoretical basis for the use of high tibial osteotomy in the treatment of knee osteoarthritis.METHODS:A computerized search was conducted in PubMed,Web of Science,CNKI and WanFang databases for relevant literature published from 2013 to 2023.The search terms used were“knee osteoarthritis,high tibial osteotomy,limb alignment,chondrocytes,biomechanics,intra-articular”in both English and Chinese.Finally,75 articles were included for review.RESULTS AND CONCLUSION:High tibial osteotomy correcting the lower limb alignment has been found to be effective in alleviating symptoms and potentially delaying or preventing the need for total knee arthroplasty.This is an important aspect of orthopedic step-down treatment in knee osteoarthritis.Maintaining a normal mechanical microenvironment is crucial for the proper functioning and maintenance of chondrocyte phenotype.Abnormal mechanical signals can be converted into intracellular chemical signals through mechanosensors like primary cilia,integrins,cytoskeleton and nucleoskeleton,resulting in disruptions to the balance of matrix metabolism and regulation of inflammatory responses.Chondrocytes after abnormal stress action still have the potential to revert to a normal phenotype under appropriate stress;correction of the mechanical microenvironment by high tibial osteotomy leads to spontaneous cartilage repair and remission of synovial inflammation.The combination of high tibial osteotomy and cartilage regeneration strategy holds promising prospects for patients with early knee osteoarthritis who are not candidates for total knee arthroplasty.
