Osteoarthritis Knee with Patellar Fracture in the Elderly: Single-Stage Fixation and Total Knee Arthroplasty

Periarticular fractures that occur in a previously osteoarthritic knee, especially in an elderly patient, will be associated with other comorbidities and is a treatment challenge. Early mobilization is a key treatment principle in the geriatric population. We present a case report of an elderly diabetic patient with osteoarthritis of the knee joint who sustained a patellar fracture and was treated with single-stage primary total knee arthroplasty and fixation of the patellar fracture.
