Distal femoral osteotomy

Area of Science:

• Orthopedic surgery
• Biomechanics
• Knee joint reconstruction

Background:

• Lower limb malalignment often requires osteotomies to unload affected knee compartments.
• Distal femoral osteotomy (DFO) is less frequently studied than high tibial osteotomy (HTO) due to the lower prevalence of valgus malalignment.
• Optimal indications and surgical techniques for DFO remain subjects of ongoing discussion and research.

Purpose of the Study:

• To review and synthesize current literature on distal femoral osteotomy (DFO).
• To delineate the established indications for performing DFO.
• To compare the outcomes of various surgical techniques employed for DFO.

Main Methods:

• Comprehensive literature search of studies reporting on distal femoral osteotomy.
• Analysis of surgical techniques, patient selection criteria, and reported outcomes.
• Comparison of DFO outcomes with existing data for high tibial osteotomy (HTO).

Main Results:

• DFO is a recognized treatment for valgus knee malalignment, aiming to realign the lower limb.
• Surgical techniques for DFO vary, with ongoing debate regarding the most effective methods.
• Outcomes data for DFO are less abundant compared to HTO, highlighting a need for further research.

Conclusions:

• Distal femoral osteotomy (DFO) is a viable surgical option for correcting valgus knee malalignment.
• Further research is needed to standardize DFO indications and surgical techniques for optimal patient outcomes.
• The role of patellofemoral arthritis as a contraindication for DFO requires further investigation.
