## TL;DR

This study found that 16.7% of patients who had ACL surgery using the transtibial technique developed osteoarthritis after an average of 94 months.

## Contribution

The study provides long-term osteoarthritis incidence data for the transtibial ACL reconstruction technique in isolated ACL injuries.

## Key findings

- 16.7% of patients developed osteoarthritis after an average of 94.1 months of follow-up.
- Most patients (83.3%) did not show signs of osteoarthritis in the operated knee.
- The study evaluated 44 knees with a minimum 5-year follow-up period.

## Abstract

Objective
: Evaluate osteoarthritis incidence in patients that undergone ACL reconstruction using the transtibial technique, with a minimum of 5 years of follow up, with isolated ACL injury.

Methods
: Patients who underwent ACL reconstruction by the same surgeon using the transtibial technique with hamstrings graft and with a minimum of 5 years of follow-up, without other injuries during the surgical procedure, were selected to undergo imaging exams of the operated knee to assess the incidence of osteoarthritis. The obtained data were evaluated by descriptive statistics.

Results
: Forty-two patients (44 knees) were evaluated, with a mean age of 31 years old (SD: 8), being 23 right knees and 28 male patients. Mean time from surgery to imaging evaluation was 94.1 months (ranging from 60 to 154 months; SD: 28). Of the evaluated knees, 37 did not have osteoarthritis (83.3%) and 7 had (16.7%).

Conclusion
: ACL reconstruction with femoral tunnel performed through the transtibial technique in patients without other associated injuries in the operated knee, using hamstrings graft, with a minimum of 5 years of follow up, showed an osteoarthritis incidence of 16.7% in a mean follow-up of 94.1 months.

Objetivo
: Avaliar a incidência de osteoartrite em pacientes submetidos à reconstrução do LCA pela técnica transtibial, com seguimento mínimo de 5 anos, com lesão isolada do LCA.

Métodos
: Pacientes que passaram por reconstrução LCA pelo mesmo cirurgião usando a técnica transtibial com enxerto de tendão dos músculos isquiotibiais e que foram acompanhados por no mínimo 5 anos, sem outras lesões durante o procedimento cirúrgico, foram selecionados para realizar exames de imagem do joelho operado a fim de avaliar a incidência de osteoartrite. Os dados obtidos foram avaliados por meio de estatísticas descritivas..

Resultados
: Foram avaliados 42 pacientes (44 joelhos), com idade média de 31 anos (DP: 8), sendo 23 joelhos direitos e 28 pacientes do sexo masculino. O tempo médio entre a cirurgia e a avaliação por imagem foi de 94,1 meses (variando de 60 a 154 meses; DP: 28). Dos joelhos avaliados, 37 não apresentavam osteoartrite (83,3%) e 7 apresentavam (16,7%).

Conclusão
: A reconstrução do LCA com túnel femoral realizado por meio da técnica transtibial em pacientes sem outras lesões associadas no joelho operado, utilizando enxerto dos tendões isquiotibiais, com um acompanhamento mínimo de 5 anos, apresentou uma incidência de osteoartrite de 16,7% em um acompanhamento médio de 94,1 meses.
