“…Another study found the increase of complications with the bilateral TKR when compared to unilateral TKR [3][4][5][6]. Odum et al [1] found that there was a high risk of developing complications for a patient who underwent bilateral total knee replacement, where 6.85% developed minor complications and 1.52% developed major complications for simultaneous group, 4.60% of the unilateral patient developed minor complications and 1.20% developed major complications with a significant p value, (p<.0001) [1].…”

“…The most significant benefit of simultaneous bilateral total knee replacement is the decrease of cost for the institution, the use of only one anesthesia and decreases the length of the patients' hospital stay [1]. Regarding the need for blood transfusion, there is a need of 1.5-fold greater with simultaneous bilateral knee replacement [6]. Simultaneous bilateral knee replacement is considered, according to many studies, to be a safer procedure and to have a lower rate of complications incidents when compared to a staged BTKR [2,7,8].…”

“…Recently, a study reported that bilateral simultaneous unicompartmental knee arthroplasty shows better functional recovery at 6 month post-operatively than unilateral TKR [36,39]. However, a direct comparison could not be made as many methodological differences existed between previous and current study.…”

Background: Total knee replacement is a common operative procedure to improve pain, function, and quality of life in patients with end stage knee osteoarthritis. The current study aimed to compare simultaneous bilateral versus unilateral total knee replacement on pain intensity and recovery of function. Methods: A total of 80 patients (bilateral 50, unilateral 30) aged 63.28 (9.4) years undergone total knee replacement participated in the current study. The participants were admitted for 5-7 days in the hospital. Participants in both the group received similar inpatient and outpatient physiotherapy sessions. Pain intensity and function capacity were assessed at baseline, day 7, and day 30 postoperatively using visual analogue scale and lower extremity functional scale, respectively. Repeated measures analysis of variance was used to analyze the data. Results: Both groups showed a significant reduction of pain intensity (Day 0, mean 8.9, SD 1.0; Day 30, mean 2.2, SD 1.3 in bilateral total knee replacement; Day 0, mean 8.8, SD 1.1; Day 30, mean 2.0, SD 1.5 in unilateral total knee replacement; p < 0.001) and improvement in the functional capacity (Day 0, mean 16.2, SD 10.1; Day 30, mean 55.6, SD 14.6 in bilateral total knee replacement; Day 0, mean 19.1, SD 9.1; Day 30, mean 56.7, SD 15.8 in unilateral total knee replacement; p < 0.001) following total knee replacement at 30 days post-operatively. However, there was a non-significant difference noted between bilateral versus unilateral total knee replacement on the reduction of pain intensity (mean changes, 6.9 versus 6.8) and improvement in the functional capacity (mean changes, 39.4 versus 37.6) at 30 days post-operatively (p > 0.05). Conclusion: Simultaneous bilateral total knee replacement was associated with a similar reduction of pain intensity and recovery of function compared to unilateral total knee replacement, suggesting the use of simultaneous bilateral total knee replacement in patients with bilateral knee osteoarthritis since its costs and rehabilitation process could be reduced compared to staged bilateral total knee replacement.

Background: No consensus has been reached on which is better in terms of functional outcomes between simultaneous bilateral and unilateral total knee arthroplasty (TKA). As patient characteristics, such as age, sex, and body mass index, have signi cant effects on functional outcomes after TKA, we should match these factors before making comparisons. This study aimed to compare time courses in functional outcomes between simultaneous bilateral TKA and unilateral TKA after matching the patient characteristics.Methods: In this retrospective study, we reviewed the clinical records of patients admitted to our hospital. After excluding the patients who did not meet the criteria, 43 underwent simultaneous bilateral TKA and 382 underwent unilateral TKA were included in this study. We performed propensity score matching for age, sex, and body mass index between simultaneous bilateral and unilateral TKA patients. We measured pain intensity, knee extensor strength, and kneespeci c functional outcomes using the new knee society score, including total score, symptoms, patient satisfaction, patient expectations, and functional activities preoperatively and at 3 and 12 months postoperatively. Two-way repeated analysis of variance was performed to compare the time courses in functional outcomes between simultaneous bilateral and unilateral TKA.Results: After propensity score matching, 40 patients each for underwent bilateral TKA and unilateral TKA were selected. Knee extensor strength in simultaneous bilateral TKA patients was signi cantly lower than that in unilateral TKA patients at 3 months postoperatively (p = 0.04). A signi cant interaction was observed between the effects of time and group on knee extensor strength (F [1, 78] = 3.338; interaction: p = 0.042; η 2 = 0.052). No signi cant interactions were found among the other variables measured.Conclusions: Patients who underwent simultaneous bilateral TKA showed delayed recovery in knee extensor strength at 3 months postoperatively, but recovered to the same level at 12 months postoperatively. Patients who underwent simultaneous bilateral TKA should undergo postoperative rehabilitation focused on alleviating delayed recovery in knee extensor strength during the acute phase.
