Ipsilateral stress fracture of the proximal fibula after total knee arthroplasty in a patient with severe valgus knee deformity on a background of Rheumatoid arthritis

Abstract

HighlightsStress fracture of the fibula after TKA is extremely rare.A severe valgus knee can be associated with a fibular stress fracture.Fibular fracture after a TKA has a risk of joint instability or aseptic loosening.Watchful waiting and close clinico-radiographic observation is essential in the follow-up of all post-operative TKA patients, especially those whom have had a TKA for a significant valgus knee deformity correction, as in this case.
