研究目的: |
评估术前 MRI 特征预测非“骨对骨”前内侧膝骨关节炎(AMOA)患者术中符合单髁置换术(UKA)适应症(即无禁忌症)的准确性。 |

|
Objectives of Study: |
To evaluate the accuracy of preoperative MRI features in predicting intraoperative suitability for unicompartmental knee arthroplasty (UKA) (i.e., absence of contraindications) in patients with non-"bone-on-bone" anteromedial knee osteoarthritis (AMOA). |

纳入标准: |
同时满足以下标准: 1.术前站立位前后位X光片显示内侧间室关节间隙狭窄,但未达到“骨对骨”(定义为内侧关节间隙 > 0mm 且 ≤ 3mm,Kellgren-Lawrence分级 II-III级)。 2.手术前进行了膝关节MRI检查,且图像质量满足诊断需求。 3.有完整的术中手术记录,能明确判断内侧间室软骨状态、ACL功能完整性及外侧间室软骨状态、髌股关节是否沟槽样改变等存在禁忌症(如承重区大面积全层软骨缺损)。 |
||||||||||||||||||||||
|
Inclusion criteria |
1.Preoperative standing anteroposterior (AP) radiograph showing medial compartment joint space narrowing but not "bone-on-bone" (defined as medial joint space > 0mm and <= 3mm, Kellgren-Lawrence grade II-III); 2.Preoperative knee MRI examination performed, with image quality sufficient for diagnostic assessment; 3.Complete intraoperative surgical records available to clearly determine the status of medial compartment cartilage, functional integrity of the ACL, lateral compartment cartilage status, patellofemoral joint (e.g., presence of groove-like changes), and other contraindications (e.g., large full-thickness cartilage defects in the weight-bearing area). |
||||||||||||||||||||||
|
排除标准: |
1.术前X光片已明确为内侧“骨对骨”(K-L IV级)或关节间隙正常(K-L I级)。 2.影像学表现为膝外翻或外侧间室OA为主。 3.MRI图像质量差,无法进行可靠评估。 4.术中记录不完整或模糊,无法作为“金标准”。 5.既往有同侧膝关节感染、骨折或韧带重建史。 6.失访或术后随访时间不足1年。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1.Preoperative radiograph showing definite medial "bone-on-bone" (K-L grade IV) or normal joint space (K-L grade I); 2.Radiological presentation of genu valgum or predominantly lateral compartment osteoarthritis (OA); 3. Poor MRI image quality, precluding reliable assessment; 4. Incomplete or ambiguous intraoperative records, making them unsuitable as the "gold standard"; 5.History of ipsilateral knee joint infection, fracture, or ligament reconstruction; 6.Lost to follow-up or postoperative follow-up duration less than 1 year. |
