“…Unicompartmental knee replacement surgery has produced encouraging results using various implant designs and techniques in recent decades. Implant survival rates of over 90% have been reported at up to 10 to 15 years after surgery ( 19 - 21 ). Given the increased interest of patients in Germany and generally increasing discussion regarding anti-allergic implants, we started using an antiallergic UKA system in 2017.…”

Background This single-center retrospective study evaluated early failure rates for an unicompartmental knee arthroplasty (UKA) system with an anti-allergic surface. Methods We studied 87 consecutive joints received an UKA at a single center between 2017 and 2020. All patients received a fully cemented anti-allergic Univation-Aesculap partial knee replacement implant with a corundum blasting surface. All joints had precise indication of unicompartmental arthroplasty according to the current criteria of this procedure. The current series was restricted to patients undergoing medial cemented UKA. Medial compartment osteoarthritis was the main indication. Results We found early failure (aseptic loosening) was documented in 20 of the 87 joints (23%). The time to failure ranged from 7 weeks to 3 years, for an estimated 33% (15–46%) cumulative hazard rate for implant loosening over three years. No cases of periprosthetic joint infection were found. On average, the patients began complaining about first symptoms during the third month after surgery. In most cases (66.66%), the cement remained fixed to the bone. Conclusions Based on these early results, the manufacturer of this implant stopped all further distribution. Continued efforts should be made to understand the clinical and radiographic outcomes of alternative and anti-allergic surface coatings in knee arthroplasty.

“…Knee osteoarthritis (KOA) is a frequent joint disease worldwide due to aging. [1,2] Knee arthroplasty (KA) is commonly used to treat advanced symptomatic KOA, and over 90% of these patients show satisfactory clinical outcomes. [3] Periprosthetic joint infection (PJI) is a devastating complication of KA leading to joint disability, decline in the quality of life, and early surgical revision.…”

A retrospective case-control study was conducted to assess whether patients who underwent sequential preoperative disinfection before primary total knee or unicompartmental arthroplasty had a lower rate of postoperative infection than those who did not. In our study, 1025 patients who underwent total knee or unicompartmental arthroplasty at 2 medical centers between September 1, 2020, and August 31, 2021, were enrolled. Statistical analysis was performed for 976 cases, including 966 and 10 uninfected and infected cases, respectively. All patients were followed up for 1-year. Data analysis was performed by binary logistic regression and adjusted for 2 confounding factors: general anesthesia and rheumatoid arthritis. IBM SPSS for Windows (version 25.0; IBM Co., Armonk, NY) software was used to perform all statistical analyses. During the study period, of the 976 patients, 10 cases of infections were detected. Sequential pre-disinfection (adjusted odds ratio 0.14, 95% confidence interval: 0.03–0.54, P = .005) could reduce the incidence of infection. Based on the results of this study, bathing the whole lower limb with 2% chlorhexidine on the night before surgery followed by 70% alcohol application 1 hour before surgery is effective for preventing periprosthetic joint infection during primary total knee or unicompartmental arthroplasty.
