History of Condylar Total Knee Arthroplasty

AbstractWe investigated the results of delirium which developed after total knee arthroplasty (TKA) and the risk factors for delirium in the patients who are older than 65 years. From March 2008 to March 2012, we performed a retrospective study on 296 knees of 265 patients who were treated with TKA. They were divided into two groups: 216 patients without delirium and 49 patients diagnosed with delirium by psychiatry. We analyzed the risk factors into three categories: First, the preoperative factors including gender, age, body mass index (BMI), clinical and functional knee joint score (Knee Society Knee Score and Knee Society Function Score) and the number of underlying diseases and associations with each disease; Second, the operative factors including the anesthesia method, amount of blood loss, operating time, laboratory factors, and transfusion count; Third, the postoperative factors such as start time of walking and duration of hospital stay were analyzed. There were significant statistical difference between two groups just in age, history of dementia, cerebrovascular disease, difference of hemoglobin and albumin, start time of walking, and duration of hospital stay. The delirium after TKA delays the postoperative ambulation and extends the hospital stay, which causes functional and socioeconomic loss of patients. Therefore, the risk factors for delirium should be assessed and proper prevention and management should be conducted.

We present a case of an 82-year-old female with a history of right total knee arthroplasty 11 years prior. She was admitted after a ground-level fall and developed progressive pain and swelling of her right knee. She had no history of complications with her total knee replacement. Radiographs of the knee and hip were negative for acute fracture, dislocation, or hardware malalignment. Knee aspiration was performed and revealed inflammatory exudate, synovial fluid consistent with crystal arthropathy, and no bacterial growth. She was diagnosed with an acute gout flare, and her symptoms significantly improved with steroids and anti-inflammatory treatment. Orthopedic surgeons should be aware of the potential for crystal arthropathy in the setting of total joint arthroplasty and evaluate for crystals before treating a presumed periprosthetic joint infection.

Abstract Background: Two-stage revision is the gold standard for treatment of infected total knee arthroplasty. The purpose of our study was to evaluate the reinfection rate of two-stage revision and to analyze the factors affecting the prognosis of two-stage revision for infected total knee arthroplasty.Methods: One hundred seven cases of two-stage revision for infected total knee arthroplasty were reviewed retrospectively from March 2006 to November 2019. We evaluated possible risk factors between success and reinfection groups. Statistical analyses included multivariable logistic regression analysis to examine the relative contribution of risk factors to the success of two-stage revision. Results: There were 19 cases of reinfection (17.8%) after two-stage revision in our center. Between the success and reinfection groups, there was a significant difference in history of cancer (p=0.015). Also, multivariable logistic regression analysis of risk factors demonstrated history of cancer (HR 5.928, p=0.015). There were no statistically significant differences in reinfection relative to other risk factors. Conclusions: In subjects undergoing two-stage revision for infected total knee arthroplasty, history of cancer was a risk factor for reinfection, though no other significant differences between risk factors was shown for reinfection.Trial registration: Retrospectively registeredLevel of evidence: IV

AbstractPrior studies suggest kinematically aligned (KA) total knee arthroplasty (TKA) provides some clinical benefits. There are no reports of self-reported outcome measures in patients treated with a calipered KA TKA that already had a contralateral mechanically aligned (MA) TKA. We performed a retrospective study and asked the following questions: (1) Were you satisfied with your MA TKA when you were treated with the KA TKA? (2) What are the Forgotten Joint Scores (FJS) and Oxford Knee Scores (OKS) in each of your knees? (3) Do you favor one knee? and (4) Did one knee recover faster? From January 2013 to January 2017, 2,378 consecutive primary TKAs were performed of which all were treated with calipered KA that uses serial verification checks incorporating measurements of bone resections and positions to restore the prearthritic or native joint lines accurately. A records review identified patients with a prior primary MA TKA in the contralateral limb. Excluded were those with a history of fracture, osteotomy, infection, or revision knee surgery in either limb. In September 2018, 78 patients (57 females) with a mean age of 73 years (range, 50–91 years) completed a follow-up evaluation consisting of the FJS and OKS questionnaires and three anchor questions. A total of 83% of patients were satisfied with the MA TKA and 92% were satisfied with the KA TKA. The KA TKA had a 15 point higher median FJS and a comparable OKS to that of the MA TKA. Also, 56% of patients favored the KA TKA, and 8% favored the MA TKA. Seventy four percent of patients favored the recovery of the KA TKA, and 6% favored the recovery of the MA TKA. Accordingly, a patient considering a contralateral KA TKA can expect that more often than not the KA TKA will have a higher FJS, a similar OKS, be their favorite knee, and recover faster. Present study is therapeutic and reflects level IV evidence.

Background. While Corynebacterium striatum and other Corynebacterium species were historically considered contaminants, they are recently being identified as pathogens with increasing frequency. Case Summary. We report the case of a 78-year-old gentleman with a three-year history of knee pain and established diagnosis of osteoarthritis referred for consideration for total knee arthroplasty. He had no knee pain with passive range-of-motion. Plain films demonstrated bony erosions atypical for osteoarthritis. Joint aspiration white blood cell count was 30,548/mm3, but multiple cultures were positive for C. striatum. The infection was successfully treated with open irrigation and debridement, complete synovectomy, and six weeks of intravenous daptomycin. Conclusion. To our knowledge, this is the first report of chronic C. striatum septic arthritis of a native joint and only the third case of C. striatum septic arthritis of the knee.

PURPOSE: To thoroughly evaluate preoperative risk factors for deep venous thrombosis (DVT) in patients with knee rheumatoid arthritis (RA) undergoing unilateral total knee arthroplasty (TKA). METHODS: Clinical data of 106 patients with knee RA who underwent unilateral TKA from August 2014 to October 2020 were collected. All patients received ultrasonic examination of the veins of both lower extremities on the third day after TKA and were divided into DVT and non-DVT groups. The associations between age, gender, body mass index (BMI), history of diabetes/hypertension, common serum lipid levels, indicators related to coagulation function, blood viscosity, erythrocyte sedimentation rate (ESR) and postoperative DVT were statistically compared and analyzed. RESULTS: ESR was significantly correlated with DVT risk after TKA (OR = 1.844, 95% CI = 1.022–2.981, P = 0.019). Receiver operating characteristic (ROC) curve analysis showed the optimal cut-off point of ESR for predicting DVT was 42 mm/h with a sensitivity of 95.5% and specificity of 66.7% . CONCLUSION: An increased preoperative ESR value is a risk factor for DVT in patients with knee RA following unilateral TKA. Pre-surgery control of ESR level and prevention of postoperative DVT in these patients are worthy of attention.
