Abstract Background Whether the cement should be used in the total knee arthroplasty (TKA) was still in controversy. This meta-analysis was performed to compare the efficacy of two kinds of fixation. Methods Randomized controlled trials (RCTs), prospective/retrospective observational studies from PubMed (on 2019 September), EMBASE (on 2019 September), and the Cochrane Central Register of Controlled Trials (CENTRAL) and Web of Science (on 2019 September) were searched. Only studies followed more than 2 years was included for the review. The PRISMA guidelines and Cochrane Handbook were adopted to assess the quality of the results reported in included studies to ensure that the results of our meta-analysis were reliable and veritable. The continuous and dichotomous outcomes were collected in a standard form, and the data were analyzed by Review Manager 5.3 software. Finally, the results were presented in the Forest plots. Results Twenty-six studies involving 2369 patients in cementless TKA and 2654 patients in cemented TKA were included. The rate of revision was not significantly different in two groups (p = 0.55). More than eight reasons caused revision were found in our study, the aseptic loosing was the most common, followed by the periprosthetic joint infection (PJI), neither was significantly different (p = 0.88 and 0.45, respectively). While significantly better long-term functional recovery was found in cementless TKA in terms of Knee Society Function Score (p = 0.004) and manipulation under anesthesia (p = 0.007). Conclusion Cementless fixation did not decrease the rate of revision after the total knee arthroplasty compared with the cemented fixation, while the long-term functional recovery was significantly better in the cementless group.

Infiltration Analgesia

Local infiltration analgesia has been widely used for pain relief in patients undergoing total knee arthroplasty. However, the effectiveness and major weakness of this technique have not been clarified; therefore, improvements in the technique have been limited. We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials and conducted a meta-analysis of randomized controlled trials comparing local infiltration analgesia with placebo infiltration in patients undergoing total knee arthroplasty. Fourteen trials involving 1305 knees were eligible. The results showed that local infiltration analgesia significantly reduced early perioperative pain and total narcotic consumption. However, postoperative functional outcomes were not significantly different between local infiltration analgesia and placebo. The pain-relieving effect of local infiltration analgesia was found to be strong but short in duration. In the future, modified delivery methods and formulas with longer durations of action and analgesia may provide a better environment for patients and therefore improve their function outcomes.

SummaryIt was the objective of this study to systematically compare the effects of apixaban versus enoxaparin in patients following total knee arthroplasty (TKA). A systematic search of Medline, EMBASE, Cochrane Central Register of Controlled Trials was conducted. Eligible studies were prospective, randomised control trials (RCT) of apixaban therapy, comparing with enoxaparin, in patients who have a high risk of venous thromboembolism (VTE) after TKA. Three RCTs involving 7,337 individuals were identified, of whom 4,057 were treated with apixaban 2.5 mg once daily, and 3280 were subcutaneous enoxaparin (40 mg once-daily or 30 mg twice-daily). Meta-analysis demonstrated the odds ratio (OR) for the composite of major VTE (proximal deep-vein thrombosis and pulmonary embolism) for apixaban versus enoxaparin was 0.47 (95% confidence interval [CI]: 0.27 to 0.82, 0.6% vs. 1.2%) and 2.09 (95%CI: 0.99 to 4.45, 0.6% vs. 0.3%), respectively. All-cause mortality occurred in 0.2% of the apixaban group versus 0.09% of the enoxaparin group (OR=1.74; 95%CI, 0.51 to 5.95). With respect to safety outcomes, apixaban was associated with a lower major bleeding rate than enoxaparin (OR=0.55, 95%CI: 0.32 to 0.96). No significant differences were detected between two strategies in other endpoints of safety profile analysed: clinically relevant non-major bleeding, raised hepatic transaminase enzyme or bilirubin concentrations and arterial thromboembolic events. In conclusion, apixaban is non-inferior to subcutaneous enoxaparin when used for the same duration, with considerable advantage regarding safety profile of major bleeding after TKA.
