          Abstract

          O objetivo do presente trabalho é apresentar os resultados iniciais, obtidos com a osteotomia valgizante de adição de tíbia, fixada com placa calço descrita por Puddu. Foram operados 29 joelhos em 27 pacientes para correção de geno-varo, sendo que, em apenas um paciente o procedimento bilateral teve objetivo profilático. O seguimento foi de 3 a 28 meses com média de 14 meses. A osteotomia proximal de tíbia foi feita de forma oblíqua iniciando na inserção distal do ligamento colateral medial em direção ao tubérculo de Gerdy. A osteotomia foi aberta e fixada com uma placa calço de Puddu. O espaço aberto da osteotomia foi preenchido por enxerto autólogo de ilíaco. A carga total era dada com 45 dias de pós-operatório. Os resultados obtidos mostraram que entre 4 a 6 meses os pacientes tiveram uma significativa melhora na sintomatologia indutora do procedimento cirúrgico. A avaliação final mostrou 27 resultados satisfatórios e apenas 2 regulares. Como conclusão essa técnica tornou a osteotomia de tíbia um procedimento reprodutível com resultados previsíveis com excelente manutenção no pós-operatorio da correção obtida no trans-operatório.

          The objective of this paper is to present the initial results obtained with the valgus tibial osteotomy, fixed with the wedge plate described by Puddu. This surgery was performed in 29 knees, in 27 patients, for correction of genu-varum, and as a profilatic measure in only one patient. The follow up time was from 3 to 28 months with average of 14 months. The proximal tibial osteotomy was done in an oblique way with start in the distal insertion of the colateral medial ligament and directed to the Gerby tubercle. The osteotomy was opened and fixed with a wedge plate of Puddu. The space opened by the osteotomy was filled with autologous iliac graft. Total weightbearing was allowed 45 days after surgery. The results show that in 4 to 6 months patients had a significant improvement of symptoms which induced to the surgical procedure. The final evaluation shows 27 satisfactory results and only 2 regular. Concluding, this technique made the tibial osteotomy a reproducible procedure with predictable results and excellent mantainance in the post-surgery of the correction obtained during surgery.

          Tibial osteotomy for genu varum. Indications, preoperative planning, and technique.

          Valgus osteotomy of the proximal tibia remains the treatment of choice for the young active patient with a progressively symptomatic varus knee and mild to moderate secondary osteoarthritis. Although the natural history of the varus knee is not well established, it is widely accepted that patients with varus malalignment who develop meniscal injuries or progressive cartilage wear will inevitably develop more severe medial compartment osteoarthritis unless the abnormal mechanics of the knee are corrected.

            Neurological complications of high tibial osteotomy--the fibular osteotomy as a causative factor: a clinical and anatomical study.

            A clinical study of 105 upper tibial osteotomies was undertaken to investigate the incidence, pathology and outcome of perioperative neurological deficit. Motor weakness and/or sensory deficit occurred in 21 patients (20%) and in half of these the deficit was permanent. For descriptive purposes the fibula was divided into four zones. The occurrence of a neurological deficit was clearly related to the level of the fibular osteotomy. An anatomical explanation is proposed for this complication, based on cadaveric studies. Due to unacceptably high levels of complications it is recommended that the fibular osteotomy should not be performed in zones II and III (from just below the fibular head to 15 cm distal to this level).

              Medial compartment arthrosis of the knee.

              When the resultant forces on the tibial plateau are displaced medially, compressive stresses cause apposition of bony tissue, thus thickening the dense subchondral bone underlying the medial plateau. Loss of the articular cartilage and an increase in subchondral bone density facilitate the progression of osteoarthrosis. Surgical management is dependent on the presence of a varus deformity; patients with medial compartment disease and varus alignment should be considered for high tibial osteotomy (HTO) or unicondylar or total knee arthroplasty (TKA), depending on their age and activity level. Patients without varus deformity and with mechanical symptoms, only mild joint-space narrowing, and pain less than 1 year are likely to benefit from arthroscopic débridement. Patients without varus alignment but with chronic pain associated with loading and more pronounced joint-space loss should be considered for HTO, or unicondylar or TKA.
