The majority of adults with mild osteogenesis imperfecta report significant functional impairment due to musculoskeletal concerns. Knee osteoarthritis is common in these patients.
Although total knee arthroplasty has become a highly efficient surgical technique for osteoarthritis, this procedure remains uncommon in patients with osteogenesis imperfecta. This current case report describes the important clinical aspects of osteogenesis imperfecta that must be considered during the planning and performance of a total knee replacement.
A 62-year-old female patient with a history of osteogenesis imperfecta suffered from severe osteoarthritis of the knee with valgus deformity. Two years after posterior stabilized total knee arthroplasty, her Hospital for Special Surgery knee score had improved from preoperative 53 points to 85 points at the final follow-up.
The current case report describes the crucial technical aspects of a successful total knee replacement in this uncommon scenario. Underlying deformities and concomitant pathologies constitute specific surgical challenges.
Special care should be taken to protect the patient from potential complications.
