概括
双层骨切除术 (DLO) 有效地纠正严重的膝关节形,保护关节并显示出良好的中期存活率. 这种手术技术恢复了自然的关节角度,导致了积极的患者结果和低转换率到全膝关节整形术 (TKA).
科学领域:
- 整形外科手术 整形外科手术
- 生物机械工程 生物机械工程
- 骨关节炎的研究研究.
背景情况:
- 瓦鲁斯膝关节骨关节炎 (OA) 通常涉及骨和骨形状的综合变形.
- 双层骨切除术 (DLO) 是这种情况下的关节保护性手术选择.
- 评估DLO的中期疗效和关节角度恢复至关重要.
研究的目的:
- 评估双级骨切除术 (DLO) 的中期存活率 (>5年).
- 评估DLO后手术后关节角的恢复情况.
- 分析临床结果和转换率到全膝关节整形术 (TKA).
主要方法:
- 对65个经过DLO的膝盖进行了回顾性分析 (中部开高骨切除术和侧侧闭远部股骨切除术).
- 最少5年的随访,记录生存率和TKA转换的时间.
- 在手术前和手术后对机械骨角 (mTFA),mMPTA,mLDFA,JLCA和JLO进行放射性评估.
- 使用IKDC,牛津膝关节得分 (OKS) 和莱斯霍姆得分来衡量临床结果.
主要成果:
- 49个膝盖 (75%的随访) 在平均8.0±1.4年后被分析.
- 中期生存率很高 (7年91.8%,5年93.9%),只有6个膝盖在5.1±2.3年后转换为TKA.
- DLO成功地恢复了生理关节角度,在中期随访时保留了腿轴 (mTFA: -0.9°) 和关节角度.
- 报告的良好的临床结果:IKDC为61.2%,OKS为36.1分,Lysholm为78.3分.
结论:
- 双层骨切除术 (DLO) 是一种有效的手术技术,用于纠正膝关节骨关节炎 (OA) 中严重的形变形.
- DLO表现出良好的中期临床结果和低转换率到全膝关节整形术 (TKA).
- 该程序成功地恢复了生理关节的对齐,保留了原生膝关节.

Knee Joint
2.3K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Ankle Joint
1.9K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
