Abstract
Abstract
Purpose
There has been a long standing debate regarding superiority of cruciate retaining total knee arthroplasty over posterior stabilized total knee arthroplasty regarding the short-term outcomes as well as long-term survivorship. The proponents of both the techniques have published vast evidence in favor of their respective surgical method and early outcome in meta-analyses does not seem to be significantly different. The decision to select either design should depend on their long-term survivorship but the literature comparing their long-term survival is sparse.This meta-analysis was conducted in order to answer the following questions: (1) Does cruciate retaining total knee arthroplasty has a better long-term survival beyond 10 years.compared to posterior stabilized total knee arthroplasty? (2) Does cruciate retaining knee arthroplasty has higher complication rates compared to posterior stabilized total knee arthroplasty?
Methods
The present systematic review and meta-analysis study was carried out following PRISMA guidelines. The following databases: Embase, Web of Science, PubMed, Scopus, the Cochrane Library, Google Scholar, and CINAHL were used to search potentially interesting articles published from database inception until January 2022. Inclusion criteria for articles were: (1) retrospective comparative studies; (2) patients who had undergone a total knee arthroplasty; (3) publications evaluating the long-term survival of cruciate-retaining (CR) versus posterior stabilizing (PS) at a minimum 10 years’ follow-up; (4) publications evaluating complications of cruciate-retaining (CR) versus posterior stabilizing (PS) at a minimum 10 years’ follow-up; and (5) publications reporting sufficient data regarding the outcomes. We used a fixed-effects design in the case of I2 < 50% and P > 0.05; if not, we adopted a random-effects design [4]. We also performed subgroups and sensitivity analysis in order to assess the possible source of heterogeneity.
Results
Database searching identified 597 studies to be screened, of which 291 abstracts were revealed as potentially eligible and finally 7 articles were included. The forest plot showed that CR had significantly better survival than PS (OR = 2.17; 95% CI: 1.69–2.80) after 10 years. However, complication rate was not significantly different between CR and PS groups (OR = 0.86; 95% CI: 0.52–1.44; P = 0.57). Subgroup analysis showed that only the period of publication constituted a source of heterogeneity in survivorship outcome. Sensitivity analysis revealed that outcomes did not differ markedly, which indicates that the meta-analysis had strong reliability.
Conclusion
The results of this meta-analysis showed that cruciate retaining prosthesis may be preferred over the posterior stabilized design in view of longer survivorship it offers However, further randomized controlled trials are recommended to confirm this finding.
