Objective. To characterize periprosthetic joint infection in patients undergoing a total hip and knee joint replacement. Materials and Methods. A total of 77 patients with periprosthetic infection following hip and knee joint replacement hospitalized in Grodno City Clinical Hospital were studied over the period of 2014-2018. Wound discharge, tissue samples, and fistula’s wall swab were used for microbiological tests. The analysis of surgical treatment of patients with deep periprosthetic knee and hip joint infection has been performed. Results. Periprosthetic infection after hip joint arthroplasty was observed in 32 (41.6%) patients, and after total knee joint arthroplasty in 45 (58.4%) patients. Surgical treatment was performed in 18 (56.3%) and 32 (71.1%) patients with periprosthetic infection following total knee and hip joint replacement, respectively. A total of 10 (31.2%) of 32 cultures from patients with periprosthetic infection after total hip joint replacement and 8 (17.8%) of 45 cultures from patients with periprosthetic infection after total knee joint replacement were positive. Overall, Staphylococcus aureus was detected in 9 (50%) of 18 positive cultures. Gram-negative aerobic bacteria (Acinetobacter baumannii, Klebsiella pneumoniae Pseudomonas aeruginosa) were detected in 4⁄10 and 5⁄8 of positive cultures from patients with periprosthetic infection of hip and knee joints, respectively. Conclusions. The most common pathogens causing periprosthetic infection of hip and knee joints were S. aureus (50%) and Gram-negative bacteria. The surgical treatment was performed in 71.4% of patients with periprosthetic joint infection.

SUMMARYDuring an average follow-up time of about 2½ years after total hip or knee-joint replacement in 8052 patients, suspected joint infection was recorded in 85 patients whose joints had not been re-operated during that period. The hospital records of 72 of these patients were examined after a further period, averaging about 5 years. Thirty-five of these had suffered continuing major problems with the joint, 18 of which had been revised, and a further 9 joints needed such treatment. Infection was confirmed in 17 of the 35. These numbers are proportionately about three times greater than those observed among a set of matched controls followed-up for a similar period. The evidence from the extended follow-up suggests that the failure rate, unassociated with infection, reached about 5% by 7 years after operation and that late infections, manifested between about 2½ and 7 years after operation, were about as frequent as those confirmed during the first 2½ years.

Background:Indian population is mainly residing in two areas- urban and rural. The literature has shown consistent results following knee joint replacement surgeries, however these studies have been done in highly efficient and equipped hospitals in urban areas. Aim: The aim of this study was to compare outcome at a rural set-up with those at a high-end teaching or corporate hospital in urban set-up from published literature. Materials and Methods: This study was an observational and retrospective analysis. Observation data was collected from January, 2020 and April, 2021. This study included follow-up of 60 total knee joint replacements. Results: In our study of total knee joint replacement surgeries in rural teaching set- up, we achieved 95.39% results (excellent) while the remaining 4.61% results were good. Conclusion: This study confirmed that results of total knee replacement are comparable to any other highly well equipped urban center, if all basic surgical principles including aseptic precautions are stringently followed-up. Further the clinical outcomes in our cases was more surgeon dependent rather than technology dependent as all surgeries were performed by one single surgeon.

Introduction: We aimed to explore the risk factors for periprosthetic joint infection (PJI) after primary artificial hip and knee joint replacements by performing a case-control study. Methodology: The clinical data of patients receiving primary hip and knee joint replacements were retrospectively analyzed. The case group included 96 patients who suffered from PJI, comprising 42 cases of hip joint replacement and 54 cases of knee joint replacement. Another 192 patients who received joint replacement at the ratio of 1:2 in the same period and did not suffer from PJI were selected as the control group. Differences between the two groups were compared in regard to etiology, pathogen, blood type, urine culture, body mass index (BMI), surgical time, intraoperative blood loss, postoperative 1st day and total drainage volumes, length of hospitalization stay, and history of surgery at the affected sites. Results: Gram-positive bacteria were the main pathogens for PJI. The most common infection after hip joint replacement was caused by Staphylococcus epidermidis, which accounted for 38.10%, while Staphylococcus aureus was mainly responsible for the infection of knee joint (40.74%). High BMI, long surgical time, large postoperative drainage volume, long hospitalization stay, history of surgery at incisions, previous use of immunosuppressants, preoperative hypoproteinemia and superficial infection were independent risk factors (p < 0.05). Conclusions: PJI after primary replacement was mainly caused by gram-positive bacteria, and patients with high BMI, long surgical time, large postoperative drainage volume, long hospitalization stay, history of surgery at incisions, previous use of immunosuppressants, preoperative hypoproteinemia and superficial infection were more vulnerable.
