Abstract
BACKGROUND: This retrospective study aimed to compare the clinical outcomes of patients with staged and simultaneous bilateral total knee arthroplasty (TKA). METHODS: The present study included 100 patients with a mean age of 62±3.72 years from 2014 to 2017. Among them, 51 and 49 patients underwent simultaneous and staged bilateral TKA, respectively. The two groups were compared regarding the range of motion (ROM), Oxford Knee Score (OKS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) improvement, and Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) scores. The mean follow-up duration was 24 months (range: 12-36 months). RESULTS: According to the results obtained from the SF-36 questionnaire (possessing eight different factors of quality of life), there was no significant difference between the two groups. Furthermore, the OKSs were 39.98±1.52 and 38.68±2.55 in the simultaneous and staged groups, respectively. Moreover, the WOMAC improvement scores were obtained at 84.15±2.2 and 83.26±2.6 in the simultaneous and staged groups, respectively. The final knee ROM was acceptable without a significant difference between the two groups. CONCLUSION: Substantial controversy about the complications, functional, and clinical outcomes has negatively affected the decision of the surgeons on conducting bilateral sequential TKA. This clinical assessment revealed that all determinants, including OKS, WOMAC, SF-36, ROM, postoperative bleeding, and hospitalization duration exhibited almost the same improvement in both groups. According to this study, no statistically significant difference exists in both procedures.
