Clinical efficacy of retention prosthetic bone cement spacers in elderly patients with periprosthetic joint infection
Abstract
Objective \nTo evaluate the clinical efficacy of retention prosthetic bone cement spacers in elderly patients with periprosthetic joint infection. \n \n \nMethods \nSeventeen retention prosthetic bone cement spacers elderly patients with periprosthetic joint infection with complete data were included in the present study. There were 8 males and 9 females, aged 60-88 years, average age was (73±8) years old, including 11 hips, 6 knee joints, thus 16 pathogens were detected, 15 cases used joint spacers, 2 cases used non-articular spacers. The time for indwelling the cement spacer was 6 to 69 months. Patient survival, postoperative infection control, functional recovery, and reoperation were recorded. Harris score and KSS score were used to evaluate joint function at the last follow-up, and pain visual analogue scale (VAS) was used to evaluate joint pain. \n \n \nResults \nAll patients were followed up for 6 to 69 months with an average of (28±15) months. There were 16 patients (16/17, 94.1%) and 1 patient (1/17, 5.9%). The remaining 15 patients had infection control (15/16, 93.7%), 1 patient (1/16, 6.3%) had spacers removed due to persistent infection, and 4 (4/17, 23.6%) patients had additional postoperative debridement operation, 2 (2/17, 11.8%) cases had complications. Except for the patients with decomposed and articular dislocation, the other 15 patients had a Harris score of (82±4) at the last follow-up, the KSS score of the knee was (79.8±2.6), the VAS score was (1.0±0.9)(0 to 4 points). \n \n \nConclusion \nRetention bone cement spacers can be obtained satisfactory infection control and functional recovery after debridement in elderly patients with periprosthetic joint infection. \n \n \nKey words: \nAged;\xa0Infection;\xa0Joint prosthesis;\xa0Spacers;\xa0Retention
