Osteotomies: The Surgical Treatment of the Valgus Knee

Abstract

Lateral compartment arthrosis from congenital valgus or the result of previous lateral meniscectomy can be a disabling condition. Realignment osteotomy, which may avoid or delay the need for a total knee replacement, is appropriate for young or middle-aged patients suffering from a painful valgus knee. Medium or large corrections can be managed with distal femoral lateral opening wedge osteotomy while minimal deformities are best treated with medial closing wedge tibial osteotomy.

Closing wedge osteotomy of the tibia and the femur in the treatment of gonarthrosis

“…For valgus gonarthrosis, the same lines are drawn; however, the second line is from the centre of the femoral head to a point located at the 50% coordinate of the tibial plateau [26] (Fig. 3).…”

“…3 Preoperative planning for valgus gonarthrosis. The correction angle is formed by the line from the centre of the femoral head to the 50% tibial plateau coordinate and the line from the centre of the ankle to the 50% coordinate [26] excellent scar which does not interfere with further surgery. The extensor muscles are carefully detached from the proximal tibia and fibula and the tibiofibular joint is exposed.…”

O uso do plasma rico em plaquetas associado ao aspirado de medular óssea na osteotomia tibial tipo puddu

“…Diagnóstico de osteoartrose unicompartimental, deficiências ligamentares crô-nicas, ou deformidades dos membros inferiores. Foram respeitadas as indicações para osteotomia valgizante recomendadas na literatura (18)(19)(20) . Os critérios de exclusão foram: perda de seguimento, solicitação do paciente para ser excluído do estudo.…”

“…A técnica empregada para a realização da osteotomia foi, como já referido anteriormente, a adição de cunha medial, à semelhança do planejamento e técnica cirúr-gica descritos por Puddu et al (19,20) .…”

Role of High Tibial Osteotomy in Chronic Posterior Cruciate Ligament and Posterolateral Corner Knee Instability

“…MRI is useful to evaluate PCL deficient knees, especially associated lesions and subchondral bone (Puddu et al, 2007). Gross et al (1992) described a classification for PCL lesion that is widely used, however Bellelli et al (2006) proposed a new MRI classification that considers each PCL bundle independently, emphasizing the importance of SE T2 and STIR sequences.…”
