【PPT】人工膝关节单髁表面置换手术配合(内侧室)

膝关节单髁置换术是一种用于治疗膝关节内侧或外侧单间室骨关节炎的精准微创手术。该手术旨在置换受损的单一髁关节面，最大程度地保留健康的骨骼、韧带及对侧间室，从而实现快速康复与更佳的功能恢复。

手术采用腰硬联合麻醉或全身麻醉。患者取仰卧位，患肢大腿根部安置止血带。常规消毒铺单后，屈曲膝关节，取膝前内侧的纵行切口。逐层切开，进入关节腔。

手术核心步骤包括：首先，进行关节探查，确认前交叉韧带完好且仅单间室病变。随后，使用专用截骨导向器，进行精确的胫骨平台和股骨髁截骨，仅去除病变的关节软骨及少量骨质。接着，安装试模测试关节活动度与稳定性。满意后，植入与实际解剖匹配的金属股骨髁假体、聚乙烯胫骨垫片及胫骨平台假体，通常采用骨水泥固定。

术毕充分冲洗，放置引流管，逐层缝合切口并加压包扎。该手术创伤小、出血少、术后疼痛轻，患者可在术后第一天辅助下地行走，显著缩短住院时间，是治疗局限性膝关节炎的理想选择。
