The subvastus or Southern approach to the knee had been described as early as 1929 but is not found in standard modern orthopedic textbooks. This approach for primary total knee arthroplasty (TKA) preserves the integrity of the extensor mechanism and maintains the vascular supply to the patella. To appreciate the potential benefits of this approach, a complete understanding of the surgical anatomy is essential. The benefits of the subvastus approach make it a valuable technique for primary TKA.
早在1929年就有人描述过股直肌下或膝关节的南方入路，但在现代标准骨科教科书中并未提及。这种初次全膝关节置换术（TKA）的入路保留了伸肌机制的完整性，并维持了髌骨的血供。为了了解这种入路的潜在益处，全面掌握手术解剖结构至关重要。股直肌下入路的益处使其成为初次TKA的一项有价值的技术。
