ABSTRACT
Abstract Objective The primary aim of the present study was to evaluate the long-term outcomes including survivorship of computer navigated distal femoral lateral opening wedge osteotomy (DFLOWO). The secondary aim was to identify the potential factors that may influence its survivorship. Methods A retrospective analysis of prospectively collected data for patients with lateral compartment arthritis who underwent navigated DFLOWO from December 2006 to November 2012 was performed. The International Knee Documentation Committee (IKDC) and Knee Injury and Osteoarthritis Outcome Score (KOOS) scores were analyzed for outcome measures. Conversion to arthroplasty during the follow-up was the end point. Results A total of 19 DFLOWOs were performed in 17 patients with a mean age of 46.6 ± 6.5 years formed the study cohort. The coronal alignment was corrected from a mean of 7.1° (2-11°) valgus to a mean of 2.1° (0.5°-3°) varus. The IKDC scores improved from mean of 39 preoperatively to 53 at the mean long-term follow-up of 9.1 years. The mean KOOS scores at the long-term follow-up were pain 71, symptoms 56, activities of daily living 82, sports and recreation 59, quality of life 43. Survivorship of the DFLOWO was 78.9% at a follow-up of 9.1 years. Presence of ≥ grade 2 according to the International Cartilage Repair Society (ICRS) cartilage degeneration in the medial compartment of the knee and >7° preoperative valgus deformity were strongly correlated with conversion to total knee arthroplasty (TKA) at the long-term follow-up (r= 0.66). ConclusionsComputer navigated DFLOWO has satisfactory clinical outcomes and 79% survivorship in long-term follow-up. Presence of more than ICRS ≥ grade 2 degenerative changes in the medial compartment of knee with > 7° preoperative valgus deformity negatively affects the survivorship of DFLOWO in the long-term follow-up.
RESUMO
Resumo Objetivo O objetivo principal do presente estudo foi avaliar os resultados a longo prazo, incluindo a sobrevivência em Osteotomia Varizante Femoral Distal com Cunha de Abertura Lateral (OVFD-CAL) utilizando navegação computadorizada. O objetivo principal do presente estudo foi avaliar os resultados a longo prazo, incluindo a sobrevivência. Métodos Foi realizada uma análise retrospectiva dos dados coletados prospectivamente de pacientes com artrite do compartimento lateral submetidos a OVFD-CAL por navegação de dezembro de 2006 a novembro de 2012. As pontuações International Knee Documentation Committee (IKDC, na sigla em inglês) e Knee Injury and Osteoarthritis Outcome Score (KOOS, na sigla em inglês) foram analisadas para medição de resultados. Conversão para artroplastia durante o acompanhamento foi o ponto final. Resultados Um total de 19 OVFD-CAL foram realizados em 17 pacientes com média de idade de 46,6 ± 6,5 anos formaram a coorte do estudo. O alinhamento coronal foi corrigido a partir de uma média de 7,1° (2-11°) de valgo para uma média de 2,1° (0,5°-3°) de varo. As pontuações do IKDC melhoraram de uma média pré-operatória de 39 para 53 no acompanhamento de médio de longo prazo de 9,1 anos. Os escores do KOOS no acompanhamento a longo prazo foram dor 71, sintomas 56, atividades da vida diária 82, esportes e recreação 59, qualidade de vida 43. A sobrevivência do OVFD-CAL foi de 78,9% em um acompanhamento de 9,1 anos. Presença de degeneração da cartilagem segundo a Sociedade Internacional de Reparação de Cartilagem (International Cartilage Repair Society [ICRS, na sigla em inglês])≥ grau 2 no compartimento medial do joelho e deformidade pré-operatória em valgo > 7° fortemente correlacionado com a conversão para artroplastia total do joelho (ATJ) no acompanhamento a longo prazo (r - 0,66). ConclusõesA OVFD-CAL por navegação computadorizada apresentou resultados clínicos satisfatórios e sobrevida de 79% no acompanhamento a longo prazo. Presença de alterações degenerativas ICRS ≥ grau 2 no compartimento medial do joelho com > 7° de deformidade pré-operatória em valgo afeta negativamente a sobrevivência da OVFD-CAL no acompanhamento de longo prazo.
