Abstract
Retrograde intramedullary fixation has been proposed to improve the rate of union providing greater stability in patients with a posterior cruciate ligament retaining femoral TKA component and decreasing soft-tissue trauma. This study assessed the clinical and radiographical outcome of retrograde intramedullary nailing (RIN) for the treatment of periprosthetic supracondylar fractures of the femur in an elderly population. Between January 2014 and December 2018, 16 patients with PSF underwent RIN. The clinical outcome was evaluated using the Knee Society Score (KSS) and the Short-form health survey (SF-12). The radiographic outcome was evaluated directly on the X-rays. Complications were also described. 13 patients (11 females and 2 males) with a mean age of 84 years old (range, 77-89) were evaluated clinically and radiographically, after a mean of 48.3 months (range, 24-73 months). The SF-12 scores were similar to normative values for subjects in the comparable age group. Radiographic union was obtained in all patients after an average of 14,8 weeks (range, 12-40 weeks) postoperatively. RIN is a safe and effective treatment for PSF, above all in the elderly population. The overall clinical and radiographic result was satisfactory.
