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.

Introduction: Total knee arthroplasty (TKA) represents a major advance in the treatment of degenerative joint disease, providing excellent restoration of joint function and pain relief. This study aim to evaluate the survival analysis of the implant, the functional and knee scores outcome and to identify a complication following Nexgen fixed bearing and posterior stabilizing total knee replacement. Methods: The present study was conducted to retrospectively review the results of all primary TKA performed at Hospital Tengku Ampuan Afzan over a period of 15 years from 2000 to 2015. The study sample consisted of 160 TKA. Oxford knee score and SF 36 were used and statistical analysis of both knee scores and functional scores were compared using SPSS software. Survivorship analysis was compared using the Kaplan-Meier method. Endpoints of implant defined as revision with removal of implant and addition or exchange of prosthetic components. Results: Functional and knee score post operatively was excellent and good. Mean range of movement of knee during the study period were left 107.50 degrees and right 106.49 degrees. Mean femoral flexion angle is 92.38 degrees and mean tibial angle is 89.48 degrees. The outcome categories for the Oxford knee score have 101 patients showed excellent result, 41 patients good, and 18 patients fair. In this study mean total SF 36 score is 80.99. Conclusions: The outcome shows that total knee replacement is a reproducible surgery for which a trained surgeon will be able to produce excellent and good results.

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.

Objective To determine the Physical Component Summary (PCS) score's minimal clinically important difference (MCID) on the Short Form 36 (SF-36) for people with stroke. Methods We conducted secondary analysis of data from a large randomized controlled trial (N = 400) in the post-hospital discharge phase of stroke rehabilitation with outcome measurement 6 and 12 months following stroke. Three methods were used for estimating the MCID: two anchor and one distribution. Method 1 compared SF-36 PCS scores at 12 months for responses to the SF-36’s Perceived Health Change (PHC) question. Method 2 compared the change in PCS score between 6 and 12 months for responses to the PHC question. Method 3 used Cohen’s method to estimate the MCID from the PCS score distribution. Results Method 1: the mean PCS score increased by 3.0 units (95% confidence interval [CI] 2.2–3.9) for each unit change in the PHC question. Method 2: the mean change in PCS score increased by 2.1 units (95% CI 1.4–2.8) for each unit change in the PHC question. Method 3: the MCID was estimated to be 1.8 units. Conclusions Our estimate of the MCID for the PCS in patients with stroke was 1.8 to 3.0 units.

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.
