概括

自主矩阵诱导的原生 (AMIC) 显示耐用性高达19年,平均存活时间为13.3年. 正确对齐的膝盖与AMIC保持了稳定性,尽管61%的转换到全膝关节整形术.

科学领域:

整形外科手术整形外科手术
再生医学是一种再生医学.
软骨的修复软骨的修复

背景情况:

自主矩阵诱导的原生 (AMIC) 为软骨修复提供了一个有前途的替代方案.
短期研究显示,AMIC的结果与微骨折技术相似.
对于AMIC的长期结果数据仍然有限.

研究的目的:

评估19年的临床结果和AMIC在膝关节软骨缺陷中的存活率.
确定影响AMIC长期成功或失败的因素.
为弥补AMIC程序的长期证据现有的差距.

主要方法:

对34个用AMIC治疗的膝盖进行了回顾性队列研究.
19年的随访评估AMIC存活率,膝盖全关节整形术 (TKA) 作为失败终点.
进行了生存分析,以确定失败的风险因素和延长生存的预测因素. 分析了临床和放射学的结果.

主要成果:

对23个膝盖进行了随访;14个 (61%) 需要TKA,平均为手术后13.3年.
手术时的年龄增加和更大的缺陷大小被确定为失败的危险因素 (p<0.05).
同时的近端骨切除与显著更长的AMIC存活率相关 (HR:0.22,p=0.019). 九个膝盖 (39%) 在没有TKA的情况下存活下来,显示稳定的临床得分,平均18.6年.

结论:

艾米克表现出耐用性,平均存活时间为13.3年,特别是在正确对齐的膝盖中.
尽管TKA转化率很高 (61%),但持续的AMIC病例在19年后显示出稳定的临床结果.
该程序为软骨修复提供了潜在的长寿,特定的患者因素影响了长期的成功.
