Several factors influencing the length of hospital stay after single or staged bilateral total knee arthroplasty (TKA) have been studied in the literature. However, there is little written about the factors affecting the length of stay after simultaneous bilateral TKA. We wished study the various factors affecting length of hospital stay (LOHS) following simultaneous bilateral TKA.
Materials and methods: We studied 100 consecutive patients who underwent simultaneous bilateral TKAs for end stage osteoarthritis of the knees. A single surgeon performed all surgeries. All patients received combined spinal and epidural anesthesia from different anesthetists. We followed a carefully designed, evidence based, care pathway system for postoperative care in all patients. Various factors such as age of the patient, sex, and co-morbidities were studied.
Results: There was a higher incidence of female patients (80%) being affected at an earlier age (mean age 64.6 years) in comparison to male patients (mean age of 71.1 years) in this series. Our study showed that (ANOVA test) the LOHS was not affected by age, sex, co-morbidities or type of anesthetist (regularly or occasionally dealing with arthroplasty surgery).
Conclusion: Simultaneous bilateral TKA can be a safe procedure when attention to details of multidisciplinary approach is given. The LOHS after simultaneous bilateral TKA can be independent of the type of anesthetist (regularly or occasionally dealing with arthroplasty surgery) and other factors such as age, sex, or co-morbidities of patients.
