Destruction of the Extensor Mechanism Following an Infected Patellar Fracture Fixation in a Patient With Diabetes: A Report of a Multidisciplinary Case.

Postoperative infections following orthopedic fixation can lead to devastating consequences, particularly in patients with comorbidities such as diabetes mellitus. We present a rare case of a 61-year-old female patient with a patella fracture treated with tension band wiring who developed a severe polymicrobial infection resulting in complete destruction of the patellar tendon. Multiple debridements, removal of implants, and prolonged targeted antibiotic therapy were necessary. Ultimately, a skin graft was required for closure, and a multidisciplinary team recommended against further reconstructive procedures due to high risk. The patient opted to retain limited function without undergoing knee arthrodesis. This case emphasizes the critical importance of early infection control, multidisciplinary coordination, and individualized patient-centered care in complex orthopedic infections.
