Background: The iASSIST (Zimmer) system is an accelerometer base navigation tool use for total knee arthroplasty (TKA) which guides surgeon to take bone cuts during surgery. The purpose of this study was to compare the functional outcome between accelerometer base iASSIST system and the conventional system. Method: A prospective study between two groups of 28 patients (14 iASSIST and 14 conventional) of primary osteoarthritis of the knee who underwent TKA using Zimmer iASSIST ™ or conventional method from January 2018 to December 2019. A single surgeon performs whole operations with the same instrumentation and same surgical approach. Pre-operative and postoperative management protocol are same for both groups. Preoperative oxford knee score, SF12 and Knee society score was taken 1 week prior to surgery and postoperative scores was taken 3 weeks after surgery. Results: There was no difference between the two groups for age, height and weight (p > 0.05). No significant difference was observed in SF 12(Physical and mental score),OKS and knee score preoperatively and postoperatively . Significant difference was observed in knee society functional score preoperatively and postoperatively between 2 groups but no significant difference was observed in difference of score. Significant correlation observed in preoperative short form(SF)12 physical component score (PCS) and preoperative oxford knee score. Conclusion: Our study concludes that despite being a useful guidance tool during TKA, iASSIST does not show any difference in functional and satisfaction outcomes when compared with the conventional method.

SummaryIntroduction.Total knee replacement (TKR) is still a challenging procedure for severe gonarthrosis patients. Deformities of knee joint (varus, valgus - more than 30 degrees), insufficiency of collateral ligaments and extensive bone loss could be a difficult problem to solve with standard knee endoprosthesis. Also in cases of revision - TKR the restoration of bone loss and regaining of stability of the joint could be a problem.Aim of the Study.The aim of our study was to analyse the results with Rotating - Hinge prosthesis after severe primary and revision TKR.Materials and Methods.34 patients (27 female, 7 male) were treated with Rotating - Hinge prosthesis during 12 years (first in 1997). Mean age of patients were 69 years. 17 operations were primary total knee arthroplasties and also 17 were revisions of the knee prosthesis. The Oxford Knee score was used for evaluation of patients satisfaction rate. The Knee Society Score was used to get objective functional results. For radiological analysis X-rays of knee joint in two projections were performed.Results.34 Oxford Knee score questionnaires were sent to patients, response we got from 27 patients (79%). Mean result from Oxford Knee score was 32 which is good. The same number of patients (34) were invited for examination using Knee Society score. The response were from 20 patients (59%). Mean result from Knee Society score was 83, which means excellent.Conclusions.Rotating-Hinge prosthesis allows to achieve good and excellent functional results and high patients satisfaction rate after severe primary and revision TKR. The biological age, general health condition, insufficiency of ligaments and previous infection in patients history have to be considered for choosing the tactics for each case.

The physical activity of the population is decreasing due to an increase in sedentary lifestyles. The aim of the study was to analyze midterm results of total knee arthroplasty according to the lifelong physical activity of the patients. We evaluated 37 patients (23 women, 14 men), with age average 70.0 years (range 53–87). We divided the patients according to lifelong physical activity. The active group included 11 patients with any history of physical activity and the passive included 26 patients with a sedentary lifestyle. No intergroup differences existed in age, gender or preoperative Knee Score. The active group had a higher postoperative Knee Score 90,5 (±5,0) compared to the passive 87,4 (±5,0). Pain after arthroplasty was experienced significantly more in the active group. Between the active 87,3 (±9,3) and passive 67,5 (±16,7) groups we measured a statistically significant difference in the improvement of Functional Score – ability to walk and climb stairs. Sedentary lifestyle affects the clinical outcomes of total knee arthroplasty. This data is demonstrating that physical activity ameliorate functional postoperative results.

Purpose:Studies report 19-33% postoperative moderate-severe pain and dissatisfaction in uncomplicated total knee arthroplasty (TKA), even after 1 year. High rates of undiagnosed depression and anxiety may have a strong impact on these unfavourable outcomes. Here we aimed to investigate the efficacy of alprazolam on postoperative analgesic use and knee functions.Methods:Seventy-six patients with a mean age of 65 ± 9.3 years (range 46-80) diagnosed with mild-moderate anxiety or depression according to the Hamilton anxiety scale (HAS) and Beck Depression Inventory (BDI) that underwent TKA were evaluated in the study. Group 1 patients were subjected to alprazolam treatment in addition to an analgesic/antiinflammatory drug, whereas Group 2 consisted of patients receiving only the standard postoperative pain management protocol. Visual analog scale (VAS) and postoperative analgesic use (g/day) were calculated to evaluate the magnitude of pain experienced. Preoperative and postoperative knee functions were assessed from the patients’ Knee Society Score and Knee Society Functional Score records.Results:A positive correlation was found between the preoperative HAS, BDI, and total postoperative analgesic use in both groups. Although the decrease in VAS was significant in both groups, postoperative analgesic need (4.25 ± 0.30 g) in Group 1 was less compared to Group 2 (4.81 ± 0.41 g) (p=0.01). The mean change in postoperative (1 month) Knee Society Score and Knee Society Functional Score were also significantly improved in Group1 compared to Group 2.Conclusion:Alprazolam can reduce postoperative analgesic use and improve knee functions by reducing the pain threshold, and enhancing overall mood via its antidepressive and anxiolytic properties in patients undergoing TKA diagnosed with mild-moderate anxiety/depression.

AbstractTwo-stage revision knee arthroplasty using an antibiotic-loaded spacer is the most widely performed procedure for infected knee arthroplasties. The clinical outcome of this type of surgery compared with aseptic joint revision with exchange of tibial and femoral components is still controversial. Therefore, we analyzed clinical outcomes of septic two-stage revisions compared with aseptic one-stage revision total knee arthroplasties (TKAs). In a retrospective study, we assessed 135 consecutive patients who underwent two-stage revision for septic TKA (52 patients) and one-stage aseptic total knee revision arthroplasty (83 patients). The average follow-up was 26.1 months for the aseptic group and 26.5 months for the septic group. For clinical evaluation, we used the Knee Society Score, Oxford Knee Score, Kujala score, Turba score, and the Short Form 36 (SF-36). Postoperative pain level was determined using the visual analog pain scale. The surgeries were performed 51 months (aseptic group) and 24 months (septic group) after primary TKA on average. The main indications for aseptic revision surgeries were instability (40%), aseptic loosening (22.4%), anterior knee pain due to pathologies of the patella (11.8%), or material wear (5.9%). In the clinical outcome, patients achieved 124.8 points in the aseptic group and 105.4 points in the septic group in the Knee Society Score. The Oxford Knee Score revealed 29.9 points for the aseptic group and 33.9 points for the septic group. For the Kujala score, we found 53.2 points in the aseptic group and 48.5 points in the septic group. For the Turba score, we found 8.4 points in the aseptic group and 10.8 points in the septic group. The SF-36 (psychical) showed 52.2 versus 49.5 points and the SF-36 (physical) showed 36.5 versus 35.4 points. Mean level of persisting pain on the visual analog scale was 3.0 (aseptic group) and 3.5 (septic group). Performing septic two-stage or aseptic one-stage tibial and femoral revision knee arthroplasty showed similar clinical outcomes in relation to objective and subjective outcome measures.

AbstractSingle-radius (SR) and multiradius (MR) total knee arthroplasties (TKAs) have produced similar outcomes, albeit most studies originate from Western nations. There are known knee kinematic differences between Western and Asian patients after TKA. The aim of this study is to compare the short-term patient-reported outcome measures (PROMs) of SR-TKA versus MR-TKA in Asians. Registry data of 133 SR-TKA versus 363 MR-TKA by a single surgeon were analyzed. Preoperative and 2-year postoperative range of motion (ROM) and PROMs were compared with Student's t-test and Mann–Whitney U-test. Logistic regression model was used to evaluate the odds of SR-TKA or MR-TKA achieving the minimum clinically important difference (MCID) of studied outcomes. Patients in both groups had similar age (65.7 ± 7.6 vs. 65.8 ± 8.2 years; p = 0.317), gender proportion (71% females vs. 79% females; p = 0.119), and ethnic distribution (80% Chinese vs. 84% Chinese; p = 0.258). Preoperatively, there were no statistically significant differences between both groups for ROM, Knee Society Score (KSS), Oxford Knee Score (OKS), and Short Form (SF)-36 scores. At 2 years, all outcomes were statistically similar or failed to achieve a difference of MCID. Controlling for all preoperative variables, SR-TKA has significantly lower odds of achieving MCID for OKS (odds ratio [OR]: 0.275, 95% confidence interval [CI]: 0.114–0.663; p = 0.004) and SF-36 Physical Component Summary (PCS) (OR: 0.547; 95% CI: 0.316–0.946; p = 0.031) compared with MR-TKA. In conclusion, there are no significant differences in the absolute PROMs between SR-TKA and MR-TKA at 2 years following TKA in Asians. However, SR-TKA has significantly lower odds of achieving the MCID for OKS and SF-36 PCS.
