The Symmetry and Predictive Factors in Two-Stage Bilateral Hip Replacement Procedures
Article
Full-text available
  • Aug 2021
Background: Approximately 10–25% of total hip replacement patients undergo a bilateral procedure. The purpose of this study was to compare selected parameters associated with the first and second hip arthroplasty in patients undergoing two-stage treatment due to bilateral hip osteoarthritis and establish the predictive factors for the second proced...

One of the leading causes of high rate of morbidity and mortality among pediatrics under the age of five years is pneumonia. A report of WHO published in 2013 stated that pneumonia is accountable for about one hundred and twenty million patients each year and the most vulnerable are developing countries. Objective: To find out the rate of occurrenc...

... However, most authors choose the staged approach, which reduces loss of blood, the rate of complications, the extent of the procedure, and the required rehabilitation period and enables the patient to more rapidly resume physical activity [8][9][10][11]16,17,20]. Another potential advantage of the staged approach over simultaneous TKR is the opportunity to determine the prognostic factors for the second procedure [7,11,17,22]. ...
... There have been no studies in which the data from the first TKR procedure were used to analyze the prognostic factors that could affect the subsequent procedure in the contralateral knee. A thorough understanding of the various factors involved in and resulting from single knee arthroplasty may considerably facilitate the course of the subsequent procedure in the other knee [7,11,22]. Knowing the parameters of the components already implanted during the first procedure (femoral component size, tibial component size, and tibial polyethylene insert size) may considerably facilitate the planning of the surgery for the other knee joint. This would also prepare the orthopedists for potential difficulties and complications, which would greatly improve the course of the procedure and the planning of rehabilitation [7,11,22]. ...

Prognostic Factors in Staged Bilateral Total Knee Arthroplasty—A Retrospective Case Series Analysis

  • May 2023
Background: Bilateral osteoarthritis of the knee is an indication for a bilateral total knee replacement (TKR) procedure. The goal of our study was to assess the sizes of the implants used during the first and second stages of TKR procedures in order to compare their size and identify the prognostic factors for the second procedure. Methods: We evaluated 44 patients who underwent staged bilateral TKR procedures. We assess the following prognostic factors from the first and second surgery: duration of anesthesia, femoral component size, tibial component size, duration of hospital stay, tibial polyethylene insert size, and the number of complications. Results: All assessed prognostic factors did not differ statistically between the first and second TKR. A strong correlation was found between the size of femoral components and the size of tibial components used during the first and second total knee arthroplasty. The mean duration of the hospital stay associated with the first TKR surgery was 6.43 days, whereas the mean duration of the second hospital stay was 5.5 days (p = 0.211). The mean sizes of the femoral components used during the first and second procedures were 5.43 and 5.2, respectively (p = 0.54). The mean sizes of the tibial components used during the first and second TKR procedures were 5.36 and 5.25, respectively (p = 0.382). The mean sizes of the tibial polyethylene inserts used during the first and second procedures were 9.45 and 9.34 (p = 0.422), respectively. The mean duration of anesthesia during the first and second knee arthroplasty was 117.04 min and 118.06 min, respectively (p = 0.457). The mean rates of recorded complications associated with the first and second TKR procedures were 0.13 and 0.06 per patient (p = 0.371). Conclusions: We observed no differences between the two stages of treatment in terms of all analyzed parameters. We observed a strong correlation between the size of femoral components used during the first and second total knee arthroplasty. We noted a strong correlation between the size of tibial components used during the first and second procedure. Slightly weaker prognostic factors include the number of complications, duration of anesthesia and tibial polyethylene insert size.
