Osteotomies for lateral compartment knee osteoarthritis

Area of Science:

• Orthopedic Surgery
• Biomechanical Engineering
• Sports Medicine

Background:

• Lateral compartment osteoarthritis (LCOA) frequently coexists with knee valgus deformity.
• Distal femoral varus osteotomy (DFVO) is a recognized surgical approach to realign the knee and offload the lateral compartment.
• DFVO is often preferred for young, active individuals seeking to avoid or delay knee arthroplasty.

Purpose of the Study:

• To review current literature on distal femoral varus osteotomy (DFVO) for lateral compartment osteoarthritis (LCOA).
• To provide guidance on patient selection, preoperative assessment, surgical techniques, and expected outcomes.
• To address the lack of consensus regarding optimal surgical parameters and long-term results.

Main Methods:

• Comprehensive literature review of studies on DFVO for LCOA.
• Analysis of patient selection criteria, surgical techniques, and reported outcomes.
• Evaluation of factors influencing return to activity and long-term implant survivorship.

Main Results:

• DFVO is a viable option for young, active patients with LCOA and valgus deformity.
• Heterogeneous study designs and outcomes highlight the need for standardized approaches.
• Limited consensus exists on optimal correction, surgical endpoints, and long-term survivorship.

Conclusions:

• Further research with standardized methodologies is needed to optimize DFVO outcomes.
• DFVO can be a valuable joint-preserving procedure when indicated appropriately.
• Clearer guidelines for patient selection and surgical technique are essential for improving results.
