Eligibility

All
Inclusion criteria
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).
Exclusion criteria
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.
