Garcia AR, Quan T, Mikula JD, Mologne MS, Best MJ, Thakkar SC. Higher modified frailty index score is associated with 30-day postoperative complications following simultaneous bilateral total knee arthroplasty. Knee 2024; 50:88-95. [PMID: 39128174 DOI: 10.1016/j.knee.2024.07.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2023] [Revised: 07/12/2024] [Accepted: 07/20/2024] [Indexed: 08/13/2024]
Abstract
BACKGROUND There is no clear consensus regarding patient populations at highest risk for complications from simultaneous bilateral total knee arthroplasty (TKA). The purpose of this study was to determine whether the comorbidities comprising the modified Frailty Index (mFI) were correlated with poor outcomes following simultaneous bilateral TKA. METHODS From 2006 to 2019, patients undergoing bilateral TKA aged 50 years or older were identified in a national database. The 5-item mFI was calculated based on the presence of five comorbidities: diabetes, congestive heart failure, hypertension, chronic obstructive pulmonary disease, and dependent functional status. Chi-squared and multivariable regression analyses were used to evaluate the association of mFI scores with postoperative complications. RESULTS The study analyzed 8,776 patients with an average age of 65 years. After adjustment on multivariable regression analysis, compared to patients with a mFI score of 0, those with a score of 1 had an increased risk of pulmonary complication (OR 3.14; p = 0.011), renal problem (OR 12.86; p = 0.022), sepsis complication (OR 2.82; p = 0.024), postoperative transfusion (OR 1.19; p = 0.012), and non-home discharge (OR 1.17; p = 0.002).Patients with a score of 2 compared to 0 had similar complications when compared. These patients had an increased risk of cardiac complication (OR 4.84; p = 0.009) and prolonged hospital stay (OR 4.06; p < 0.001). CONCLUSION Increased mFI scores were associated with significantly higher complication rates in patients undergoing simultaneous bilateral TKA compared to unilateral TKA. Our results can be used to identify which patients may need a staged bilateral TKA or preoperative optimization to safely undergo a simultaneous bilateral TKA. LEVEL OF EVIDENCE III.

Abstract
INTRODUCTION The choice between simultaneous and staged bilateral total knee arthroplasty (BTKA) remains controversial. Age-adjusted Charlson Comorbidity Index(CCI) is a promising tool for risk-stratification. We aimed to compare the outcomes between patients who underwent simultaneous and staged BTKA, stratified by age-adjusted CCI scores. MATERIALS AND METHODS We conducted this retrospective, single-surgeon case series from 2010 to 2020. This study consisted of 1558 simultaneous BTKA and 786 staged BTKA procedures. The outcome domains included 30-day and 90-day readmission and 1-year reoperation events. We performed multivariate regression analysis to compare the risk of readmission and reoperation following simultaneous and staged BTKA. Other factors included age, sex, body mass index, diabetes mellitus, rheumatoid arthritis, smoking, receiving thromboprophylaxis and blood transfusion. RESULTS The rates of 30-day, 90-day readmission and 1-year reoperation following simultaneous BTKA was 1.99%, 2.70% and 0.71%, respectively. The rates of 30-day, 90-day readmission and 1-year reoperation following staged BTKA was 0.89%, 1.78% and 0.89%, respectively. For patients with age-adjusted CCI ≥ 4 points, simultaneous BTKA was associated with a higher risk of 30-day (aOR:3.369, 95% CI:0.990-11.466) and 90-day readmission (aOR:2.310, 95% CI:0.942-5.668). In patients with age-adjusted CCI ≤ 3 points, the risk of readmission and reoperation was not different between simultaneous or staged BTKA. CONCLUSION Simultaneous BTKA was associated with an increased risk of short-term readmissions in patients with age-adjusted CCI ≥ 4 points but not in those with age-adjusted CCI ≤ 3 points. Age-adjusted CCI can be an effective index for the choice between simultaneous and staged BTKA procedures.

Abstract
Background While studies have assessed comparative rates of restoration of shoulder function and alleviation of symptoms, comparative systemic postoperative complication rates between biceps tenotomy and tenodesis have yet to be assessed. The purpose of the present study was to use a national administrative database to perform a comprehensive investigation into 30-day complication rates after biceps tenotomy versus tenodesis, thus providing valuable insights for informed decision-making by clinicians and patients regarding the optimal surgical approach for pathologies of the long head of the biceps tendon. Methods The National Surgical Quality Improvement Program database was queried to analyze postoperative complication rates and metrics associated with biceps tenotomy and tenodesis. Patient data spanning from 2012 to 2021 was extracted, with relevant variables assessed to identify and compare these two surgical approaches. Adjusted and unadjusted analyses were utilized to analyze patient demographics, comorbidities, operative times, lengths of stay, readmissions, adverse events, and yearly surgical volume, along with trends in usage, across cohorts. Results Of 11,527 total patients, 264 (2.29%), 6826 (59.22%), and 4437 (38.49%) underwent tenotomy, tenodesis with open repair, and tenodesis with arthroscopic repair, respectively. Tenotomy operative times ([mean ± SD]: 66.25 ± 44.76 minutes) were shorter than those for open tenodesis (78.83 ± 41.82) and arthroscopic tenodesis (75.98 ± 40.16). Conversely, tenotomy patients had longer hospital days (0.88 ± 4.86 days) relative to open tenodesis (.08 ± 1.55) and arthroscopic tenodesis (.12 ± 2.70). Multivariable logistic regression controlling for demographics and comorbidities demonstrated that patients undergoing tenodesis were less likely to be readmitted (adjusted odds ratio [AOR]: 0.42, 95% confidence interval [CI]: 0.17-0.98, P = .050) or sustain serious adverse events (AOR: 0.27, 95% CI: 0.13-0.57, P < .001), but equally likely to sustain minor adverse events (AOR: 0.87, CI: 0.21-3.68, P = .850), compared with patients undergoing tenotomy. Lastly, comparing utilization rates from 2012 to 2021 revealed a significant decrease in the proportion of tenotomy (from 6.2% to 1.0%) compared to open tenodesis (from 41.0% to 57.3%) and arthroscopic tenodesis (52.8% to 41.64%; P trend = .001). Conclusion To our knowledge, this is the first large national database study investigating postoperative complication rates between the various surgical treatments for pathologies of the long head of the biceps tendon. Our results suggest that tenodesis yields fewer serious adverse events and lower readmission rates than tenotomy. We also found a shorter operative time for tenotomy. These findings support the increased utilization of tenodesis relative to tenotomy in recent years.

Abstract
Although bilateral simultaneous total knee arthroplasty (BSTKA) is an effective treatment for bilateral knee osteoarthritis, safety concerns and lack of precise patient selection criteria persist. The purpose of this retrospective study was to determine the complication rate and the role of frailty in patient selection for BSTKA. We analyzed data from 434 patients who underwent BSTKA between February 2012 and January 2021, examining demographic factors and preoperative blood test results. Complications occurred in 77 patients (18%), with anemia requiring transfusion being the most common (26 patients, 5.9%). In the univariate analysis, age ≥ 75 years, age-adjusted Charlson Comorbidity Index ≥ 5, age-adjusted 5-factor modified Frailty Index (aamFI-5) ≥ 3, hemoglobin ≤ 11.0 g/dL, albumin ≤ 3.5 g/dL, estimated glomerular filtration rate < 45 ml/dl/1.73 m2, and D-dimer ≥ 2.0 μg/mL contributed to postoperative complications (p < 0.05). Multivariate analysis identified aamFI-5 ≥ 3 as an independent risk factor (p = 0.002). Our findings underscore the practical utility of aamFI-5 in predicting complications after BSTKA, providing valuable guidance to surgeons in the selection of BSTKA candidates and ultimately improving clinical outcomes.

Abstract
BACKGROUND The need for thromboprophylaxis in Asian patients after primary total joint arthroplasty (TJA) remains inconclusive. We aimed to identify the risk factors for venous thromboembolism (VTE) events following primary TJA in a Taiwanese population. METHODS From January 2010 to December 2019, we studied 7511 patients receiving primary TJA from a single surgeon. We validated the incidence and risk factors for 30- and 90-day symptomatic VTE events, including age, sex, body mass index (BMI), smoking, medical comorbidities, VTE history, presence of varicose veins, total knee arthroplasty (TKA) vs total hip arthroplasty (THA), unilateral vs bilateral procedure and receipt of VTE prophylaxis, transfusion, and length of stay. RESULTS The incidence of 30- and 90-day symptomatic VTE events was 0.33% and 0.44%, respectively. Multivariate regression analysis showed that BMI ≥30 (adjusted odds ratio (aOR): 4.862, 95% CI, 1.776-13.313), bilateral TJA procedure (aOR: 2.665, 95% CI, 1.000-7.104), and presence of varicose veins (aOR: 9.946, 95% CI, 1.099-90.024) were associated with increased odds of 30-day symptomatic VTE events. Age ≥77 years (aOR, 2.358, 95% CI, 1.034-5.381) and BMI ≥30 (aOR: 2.832, 95% CI, 1.039-7.721) were associated with increased odds of 90-day symptomatic VTE events. CONCLUSION Age ≥77 years, BMI ≥30, bilateral TJA procedure, or presence of varicose veins may require pharmacological thromboprophylaxis because such patients have a higher risk of VTE after primary TJA.

No Difference in 30-day Mortality Between Patients Undergoing Bilateral Simultaneous Total Knee Arthroplasty With Technology Assistance Compared to Conventional Instrumentation. HSS J 2024; 20:230-236. [PMID: 39282001 PMCID: PMC11393621 DOI: 10.1177/15563316231160155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 11/29/2022] [Indexed: 09/18/2024]
Abstract
Background: Bilateral simultaneous total knee arthroplasty (BSTKA) has decreased in frequency due to concerns about higher rates of early mortality and complications than unilateral or staged surgeries. Purpose: We sought to evaluate whether technology assistance (encompassing robotics and computer assistance) decreases early mortality following BSTKA. Methods: We conducted a retrospective cohort study using a national all-payer claims database. Patients who underwent BSTKA from October 2015 to December 2020 were identified. Univariate and multivariable analyses were conducted to compare outcomes in patients who underwent BSTKA with technology assistance compared to conventional instrumentation. The primary outcome was 30-day postoperative mortality. Secondary outcomes were respiratory failure and fat embolism. A post-hoc analysis was performed to evaluate length of stay, readmission, and other medical complications. Results: A total of 14,870 patients who underwent BSTKA were included in this study. Of these, 860 patients underwent technology-assisted BSTKA, and 14,010 patients underwent BSTKA without technology assistance. After a multivariable analysis, patients who underwent technology-assisted BSTKA had equivalent odds of 30-day mortality compared to those who underwent BSTKA without technology assistance. Technology assistance was not protective against the development of acute respiratory failure or fat embolism. Conclusion: This retrospective cohort study found no differences in the rates of 30-day mortality, respiratory failure, or fat embolism after technology-assisted BSTKA compared to conventional BSTKA. On the post-hoc analysis, technology use was associated with a decreased length of stay, lower readmission risk, and decreased rates of deep vein thrombosis, pulmonary embolism, and blood transfusion.

Abstract
BACKGROUND Windswept deformity (WSD) in relation to advanced osteoarthritis (OA) presents a significant surgical challenge in total knee arthroplasty (TKA). The primary goal of this study is to investigate the Prevalance of WSD associated osteoarthritis who have undergone total knee arthroplasty. The secondary goal is to explore the causes of WSD and its association with spinal deformity or leg length discrepancy in these patients. Finally, we evaluate the surgical outcomes of phenotype-considered kinematically aligned TKA (KA-TKA) in treating patients with WSD. METHODS A review was conducted on data from 40 knees of 33 WSD patients who underwent phenotype-considered KA-TKA from August 2016 to December 2020. Patient demographics, associated diseases, preoperative and postoperative knee alignment angles, range of motion (ROM), Oxford Knee Score (OKS), and Knee Society Score (KSS) were collected and analyzed. Subgroup analysis for comparing the results between valgus and varus knees were also performed. RESULTS Within the studied cohort of WSD patients, a substantial 64% displayed concomitant coronal spinal imbalance and 21% evidenced leg length discrepancy. Postoperative improvements were notable in knee alignments, ROM, OKS, and KSS following the application of the phenotype-considered KA-TKA approach. There were significant differences in the knee alignment angles, including mHKA, LDFA, and MPTA, between the valgus and varus side of knees (P = 0.018). However, no statistically significant difference were observed in the functional scores, comprising ROM, OKS, and KSS, between valgus and varus knees. CONCLUSIONS A high percentage of patients with WSD exhibited coronal spinal imbalance and leg length discrepancy. Phenotype-considered KA-TKA effectively provided alignment targets for the treatment of both varus and valgus knees in patients with WSD, achieving excellent short-term outcomes and acceptable knee alignment.

In-hospital complications and readmission patterns in 13,937 patients with developmental dysplasia of the hip undergoing total hip arthroplasty: Evidence from the Chinese national database. Surgeon 2024; 22:99-106. [PMID: 37872053 DOI: 10.1016/j.surge.2023.10.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 08/15/2023] [Accepted: 10/10/2023] [Indexed: 10/25/2023]
Abstract
PURPOSE Clarifying the prognosis and readmission patterns of patients with developmental dysplasia of the hip (DDH) following total hip arthroplasty (THA) would provide important references for clinical management for this population. Using the Chinese national inpatient database (i.e., Hospital Quality Monitoring System [HQMS]), we aimed to compare in-hospital complications and readmission patterns following THA in patients with DDH and primary osteoarthritis (OA). METHODS Patients undergoing THA for DDH and OA between 2013 and 2019 were identified using the HQMS. Demographics and clinical characteristics were compared between the two groups. After propensity score matching, in-hospital complications and readmission patterns were compared using a logistic regression model. RESULTS According to the analysis of 13,937 propensity-score matched pairs, there were no significant differences in the incidence of in-hospital death (0.01 % vs 0.04 %, P = 0.142), transfusion (8.09 % vs 7.89 %, P = 0.536), wound infection (0.31 % vs 0.25 %, P = 0.364), deep venous thrombosis (0.45 % vs 0.43 %, P = 0.786), pulmonary embolism (0.03 % vs 0.05 %, P = 0.372) or all-cause readmission (2.87 % vs 3.12 %, P = 0.219) between two groups. However, DDH patients had higher surgical readmission rates than OA patients (1.43 % vs 1.14 %, P = 0.033). When analyzing causes of surgical readmission, DDH patients had increased risk of dislocation (0.37 % vs 0.21 %, P = 0.011) and aseptic loosening (0.17 % vs 0.07 %, P = 0.024) than OA patients. CONCLUSION DDH patients had an increased risk of surgical readmission following THA, mainly driven by dislocation and aseptic loosening, which should be recognized and appropriately prevented.

Abstract
In staged bilateral total knee arthroplasty (BTKA), the intersurgical time is yet to be determined. This study aimed to (1) test for differences in in-hospital metrics between the index and contralateral TKA and (2) determine the safest intersurgical time interval to minimize adverse outcomes after the contralateral surgery. The National Readmissions Database was queried for patients who received staged BTKA (2016-2017). A total of 20,279 patients were included. Demographics, comorbidities, baseline determinants, and intersurgical time between index and contralateral TKAs (≤ 3 month, 4-6 months, 7-9 months, and 10-12 months intervals) were captured. Outcomes included healthcare utilization (length of stay [LOS] and nonhome discharge), in-hospital costs, and in-hospital complications. Outcomes were compared between index versus contralateral surgeries and among contralateral surgeries of various intersurgical intervals. Contralateral surgeries had shorter LOS (2.2 ± 1.9 vs. 2.4 ± 2.0 days; p < 0.001), lower nonhome discharge (n = 2692[13.2%] vs. n = 2963[14.7%]; p = 0.001), and in-hospital costs ($16,476 ± $7,404 vs. 16,774 ± $9,621; p < 0.001), but similar rates of nonmechanical (p = 0.40) complications compared with index TKA. Multivariable regression demonstrated that intersurgical time was not associated with nonmechanical complications or transfusion, or 30-day readmission (p > 0.05, each). Compared with the less than or equal to 3-month interval, the 4 to 6-month interval exhibited highest odds ratio (OR) of any infection (OR: 1.81; 95% confidence interval [CI]: [1.13-2.88]; p = 0.013), urinary tract infection (OR:1.81, 95%CI: [1.13-2.90]; p = 0.014), and any-cardiac complications (OR:1.17; 95%CI: [1.01-1.35]; p = 0.037). Patients in the 10-12-month cohort had lowest odds of posthemorrhagic anemia (OR: 0.84; 95% CI: [0.72-0.98]; p = 0.03). Overall, the second surgery of a staged BTKA has lower healthcare utilization despite similar complication rates. While patients in the 10 to 12-month intersurgical interval had the most favorable overall safety profile, no single interval exhibited consistently lower complications for all measured outcomes. Special care pathways should be optimized to care for patients undergoing staged BTKA.

Abstract
BACKGROUND Simultaneous bilateral total hip arthroplasty (sbTHA) continues to be performed in patients who have bilateral end-stage osteoarthritis. However, few studies have evaluated the risk associated with this practice compared to unilateral total hip arthroplasty (THA). METHODS Using a large national database, primary, elective sbTHAs, and unilateral THAs were identified from January 1, 2015 to December 31, 2021. The sbTHAs were matched to unilateral THAs at a 1:5 ratio on age, sex, and pertinent comorbidities. Patient characteristics and comorbidities, and hospital factors were compared between both cohorts. Additionally, 90-day risk of postoperative complications, readmissions, and in-hospital deaths were assessed. After matching, 2,913 sbTHAs were compared to 14,565 unilateral THAs with an average age of 58.5 ± 10.0 years. RESULTS Compared to unilateral patients, sbTHA patients demonstrated higher rates of pulmonary embolism (PE) (0.4 versus 0.2%, P = .002), acute renal failure (1.2 versus 0.7%, P = .007), acute blood loss anemia (30.4 versus 16.7%, P < .001), and need for transfusion (6.6 versus 1.8%, P < .001). After accounting for confounders, sbTHA patients demonstrated increased risk of PE (adjusted odds ratio [aOR]: 3.76, 95% CI: 1.84 to 7.70, P < .001), acute renal failure (aOR: 1.83, 95% CI: 1.23 to 2.72, P = .003), acute blood loss anemia (aOR: 2.3, 95% CI: 2.10 to 2.53, P < .001), and transfusion (aOR: 4.08, 95% CI: 3.35 to 4.98, P < .001) compared to unilateral THA patients. CONCLUSION The practice of performing sbTHA was associated with an increased risk of PE, acute renal failure, and risk of transfusion. Careful evaluation of patient-specific risk factors is warranted when considering these bilateral procedures.

Abstract
BACKGROUND Total knee arthroplasty (TKA) is a highly successful surgical procedure that decreases pain and improves function. Many patients who undergo TKA may require surgical intervention on both extremities because of bilateral osteoarthritis. The purpose of this study was to evaluate the safety of simultaneous bilateral TKA compared with that of unilateral TKA. METHODS Patients who underwent unilateral or simultaneous bilateral primary, elective TKA from 2015 to 2020 were identified using the Premier Healthcare Database. Subsequently, the simultaneous bilateral TKA cohort was matched to the unilateral TKA cohort in a 1:6 ratio by age, sex, race, and presence of pertinent comorbidities. Patient characteristics, hospital factors, and comorbidities were compared between the cohorts. The 90-day risks of postoperative complications, readmission, and in-hospital death were assessed. Differences were assessed using univariable regression, and multivariable regression analyses were performed to account for potential confounders. RESULTS Overall, 21,044 patients who underwent simultaneous bilateral TKA and 126,264 matched patients who underwent unilateral TKA were included. After accounting for confounding factors, patients who underwent simultaneous bilateral TKA demonstrated a significantly increased risk of postoperative complications, including pulmonary embolism (adjusted odds ratio [OR], 2.13 [95% confidence interval (CI), 1.57 to 2.89]; p < 0.001), stroke (adjusted OR, 2.21 [95% CI, 1.42 to 3.42]; p < 0.001), acute blood loss anemia (adjusted OR, 2.06 [95% CI, 1.99 to 2.13]; p < 0.001), and transfusion (adjusted OR, 7.84 [95% CI, 7.16 to 8.59]; p < 0.001). Patients who underwent simultaneous bilateral TKA were at increased risk of 90-day readmission (adjusted OR, 1.35 [95% CI, 1.24 to 1.48]; p < 0.001). CONCLUSIONS Simultaneous bilateral TKA was associated with increased rates of complications including pulmonary embolism, stroke, and transfusion. Orthopaedic surgeons and patients should consider these potential complications when contemplating simultaneous bilateral TKA. When simultaneous bilateral TKA is pursued, patient counseling and thorough medical optimization should be performed. LEVEL OF EVIDENCE Therapeutic Level III .

Abstract
Objectives This study aims to analyze the safety of a simultaneous bilateral total knee arthroplasty (SBTKA) and to investigate patients' satisfaction with the procedure performed concomitantly. Methods In a prospective study, we evaluated 45 patients undergoing SBTKA performed by two surgical teams. The mean age of the patients was 66.9 years; 33 subjects were female (73.3%) and 12 (26.6%) were male. We followed a protocol of intra- and postoperatively measures to ensure the safety of this procedure. We evaluated the surgery time and blood loss by hematocrit (Ht) and hemoglobin (Hb) levels on the first postoperative day, the percentage of patients who received a transfusion of packed red blood cells, and the number of required units. We also recorded perioperative complications, and, at the end of 3 months, we asked patients about their preference between the simultaneous or staged procedure. Results The mean surgery time was 169 minutes. In the postoperative period, there was an average decrease of 28.2% in Htc and 27.0% in Hgb. A total of 16 patients (35.5%) received a transfusion of packed red blood cells (mean, 1.75 units per patient requiring a transfusion). There were 12 minor complications (26.6%) and 2 major complications (4.4%); furthermore, no patient had a clinical diagnosis of deep vein thrombosis, and there were no deaths. Conclusions: The SBTKA procedure may be considered safe if performed in selected patients and with a care protocol to prevent complications. This type of procedure was unanimously approved by patients.

Abstract
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.

Abstract
BACKGROUND The efficacy and safety of tranexamic acid (TXA) in reducing blood loss following total knee arthroplasty (TKA) in patients with osteoarthritis have been widely confirmed. However, there is still a paucity of the evidences regarding the effectiveness of TXA in patients with rheumatoid arthritis (RA). The purpose of the study is to explore the efficacy and safety of intravenous TXA on blood loss and transfusion risk following simultaneous bilateral TKA (SBTKA) in patients with RA. METHODS As a multicenter retrospective study, a total of 74 patients diagnosed with RA who underwent SBTKA were assigned into TXA group (15 mg/kg intravenous TXA before skin incision, n = 50) and control group (no TXA use, n = 24). The primary outcomes were total blood loss (TBL) and intraoperative blood loss (IBL). The secondary outcomes were hemoglobin (Hb) and hematocrit (Hct) drop on postoperative day 3, transfusion rate and volume, ambulation time, length of stay, hospitalization expenses and the incidence of complications. RESULTS The mean TBL, IBL and transfusion volume in TXA group were significantly lower than those in control group. The Hb and Hct drop on postoperative day 3 in control group were higher than those in TXA group (p<0.05). The similar trend was detected on transfusion rate, ambulation time and length of stay. The incidence of complications and hospitalization expenses did not differ significantly between the two groups (p>0.05). CONCLUSIONS TXA could effectively reduce blood loss, decrease transfusion risk, shorten ambulation time and length of stay following SBTKA in patients with RA, without increasing the risk of complications.

Abstract
Objective: To ascertain the correlation between shoe size and sizes of femoral and tibial components of total knee replacement preoperatively in patients undergoing total knee arthroplasty.
Study design: Prospective cohort study
Study settings and duration: This study was conducted at department of orthopedic surgery, Shifa International Hospital, Islamabad from July 2020 – December 2020.
Material and methods: Sample size was calculated using WHO calculator and it was 43 patients in total. Patients were approached through non-probability consecutive sampling. Shoe size of patients was measured using a Brannock device. During surgery, Implant model and sizes of the femoral and tibial components implanted during knee replacement were noted. Data was analyzed with the help of SPSS version 24. We applied Pearson’s correlation cofficeint. P value ≤ 0.05 was considered significant.
Results: Out of 43, there were 9(20.9%) male and female 34(79.1%). Mean age of patients was 51.7±6.8 (SD). We found good positive correlation between shoe size and tibial component (p=<0.001). Positive co relation was found between femoral component and shoe size (p=0.001). Shoe size predict 72% of Tibial component and 65% femoral component.
Conclusion: Shoe size is effective and safe predictors of total knee replacement components pre-operatively. This procedure is more accurate and less labor intensive. Accurate templating result in less surgical duration and provide several benefits to patients and health care providers.

The synovial fluid calprotectin lateral flow test for the diagnosis of chronic prosthetic joint infection in failed primary and revision total hip and knee arthroplasty. INTERNATIONAL ORTHOPAEDICS 2023; 47:929-944. [PMID: 36656361 PMCID: PMC10014771 DOI: 10.1007/s00264-023-05691-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 01/04/2023] [Indexed: 01/20/2023]
Abstract
PURPOSE The diagnostic criteria of prosthetic joint infection (PJI) recommended by the most commonly used diagnostic algorithms can be obscured or distorted by other inflammatory processes or aseptic pathology. Furthermore, the most reliable diagnostic criteria are garnered during revision surgery. A robust, reliable addition to the preoperative diagnostic cascade is warranted. Calprotectin has been shown to be an excellent diagnostic marker for PJI. In this study, we aimed to evaluate a lateral flow test (LFT) in the challenging patient cohort of a national referral centre for revision arthroplasty. METHODS Beginning in March 2019, we prospectively included patients scheduled for arthroplasty exchange of a total hip (THA) or knee arthroplasty (TKA). Synovial fluid samples were collected intra-operatively. We used the International Consensus Meeting of 2018 (ICM) score as the gold standard. We then compared the pre-operative ICM score with the LFT result to calculate its diagnostic accuracy as a standalone pre-operative marker and in combination with the ICM score as part of an expanded diagnostic workup. RESULTS A total of 137 patients with a mean age of 67 (± 13) years with 53 THA and 84 TKA were included. Ninety-nine patients (72.8%) were not infected, 34 (25.0) were infected, and four (2.9%) had an inconclusive final score and could not be classified after surgery. The calprotectin LFT had a sensitivity (95% confidence interval) of 0.94 (0.80-0.99) and a specificity of 0.87 (0.79-0.93). The area under the receiver operating characteristic curve (AUC) for the calprotectin LFT was 0.94 (0.89-0.99). In nine cases with an inconclusive pre-operative ICM score, the calprotectin LFT would have led to the correct diagnosis of PJI. CONCLUSIONS The synovial fluid calprotectin LFT shows excellent diagnostic metrics both as a rule-in and a rule-out test, even in a challenging patient cohort with cases of severe osteolysis, wear disease, numerous preceding surgeries, and poor soft tissue conditions, which can impair the common diagnostic criteria. As it is available pre-operatively, this test might prove to be a very useful addition to the diagnostic algorithm.

[PMID: 36162708 DOI: 10.1016/j.arth.2022.09.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 09/13/2022] [Accepted: 09/18/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Decreased cost associated with same-day discharge (SDD) total knee arthroplasty (TKA) has led to an increased interest in this topic. The purpose of this study is to investigate whether there is a population of TKA patients in which SDD has similar rates of 30-day complications compared to patients discharged on postoperative day 1 or 2. METHODS Using the American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2018, 6,327 TKA patients who had a SDD (length of stay [LOS] = 0) were matched to TKA patients who had an LOS of 1 or 2 days. All SDD patients were successfully matched 1:1 using the morbidity probability variable (a composite variable of demographics, comorbidities, and laboratory values). Patients were divided into quartiles based on their morbidity probability. Bivariate logistic regressions were then used to compare any complication and major complication rates in the SDD quartiles to the corresponding quartiles with an LOS of 1 or 2 days. RESULTS When comparing the 1st quartiles (healthiest), there was no difference between the cohorts in any complication (odds ratio [OR] = 0.960, 95% CI 0.552-1.670, P = .866) and major complications (OR = 0.999, 95% CI = 0.448-2.231, P = .999). The same was observed in quartile 2 (any complications: OR = 1.161, 95% CI = 0.720-1.874, P = .540). Comparing the third quartiles, there was an increase in all complications with SDD (OR = 1.784, 95% CI = 1.125-2.829, P = .014), but no difference in major complications (OR = 1.635, 95% CI = 0.874-3.061, P = .124). Comparing the fourth quartiles (least healthy), there was an increase in all complications (OR = 1.384, 95% CI = 1.013-1.892, P = .042) and major complications (OR = 1.711, 95% CI = 1.048-2.793, P = .032) with SDD. CONCLUSION The unhealthiest 50% of patients in this study who underwent SDD TKA were at an increased risk of having any complication, calling into question the current state of patient selection for SDD TKA.

Temporal trends in the rate of complications and prolonged length of stay relative to body mass index in patients undergoing total knee arthroplasty from 2012 to 2020. Knee 2023; 41:266-273. [PMID: 36773372 DOI: 10.1016/j.knee.2023.01.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 12/13/2022] [Accepted: 01/26/2023] [Indexed: 02/13/2023]
Abstract
BACKGROUND Elevated body mass index (BMI) is a risk factor for complications following total knee arthroplasty (TKA). Thus, we believe it is important to constantly re-evaluate the relationship between BMI and complication risk following TKA. METHOD Patients undergoing primary TKA were identified in a national database from 2012-2020. Rates of major complications, minor complications, and length of stay (LOS) greater than 2 days were calculated. The prevalence of postoperative outcomes were calculated per unit of BMI and then multiplied by a factor of 10^2 or 10^3 in order to create adjusted-BMI (aBMI). To isolate the effect of aBMI on postoperative outcomes, changes over time were analyzed using linear regression analysis controlling for age, sex, American Society of Anesthesiology (ASA) classification and smoking status. RESULTS 365,333 patients were included. Mean BMI 33 ± 6.8. 10,616 (2.9%) of patients had a major postoperative complication, 9,345 (2.6%) minor complications, 3,277 (0.9%) had a deep or superficial surgical site infection (SSI). 133,563 (37%) of patients had LOS > 2 days. From 2012-2020, the ratio of major complications to aBMI decreased significantly by an average of -2.7% per year. The ratio of patients with LOS > 2 days to aBMI decreased significantly by -27% per year. The ratio of SSI to aBMI increased significantly by 10.8% per year. CONCLUSIONS From 2012 to 2020, the ratio of major complications and extended LOS following TKA as a function of BMI has decreased significantly, while the ratio of SSI as a function of BMI has doubled.

Abstract
Objective This study aimed to explore the main risk factors affecting Total Knee Arthroplasty (TKA) patients and develop a predictive nomogram of hospital stay. Methods In total, 2,622 patients undergoing TKA in Singapore were included in this retrospective cohort study. Hospital extension was defined based on the 75% quartile (Q3) of hospital stay. We randomly divided all patients into two groups using a 7:3 ratio of training and validation groups. We performed univariate analyses of the training group, in which variables with P-values < 0.05 were included and then subjected to multivariate analysis. The multivariable logistic regression analysis was applied to build a predicting nomogram, using variable P-values < 0.01. To evaluate the prediction ability of the model, we calculated the C-index. The ROC, Calibration, and DCA curves were drawn to assess the model. Finally, we verified the accuracy of the model using the validation group and by also using the C-index. The ROC curve, Calibration curve, and DCA curve were then applied to evaluate the model in the validation group. Results The final study included 2,266 patients. The 75% quartile (Q3) of hospital stay was six days. In total, 457 (20.17%) patients had hospital extensions. There were 1,588 patients in the training group and 678 patients in the validation group. Age, Hb, D.M., Operation Duration, Procedure Description, Day of Operation, Repeat Operation, and Blood Transfusion were used to build the prediction model. The C-index was 0.680 (95% CI: 0.734-0.626) in the training group and 0.710 (95% CI: 0.742-0.678) for the validation set. The calibration curve and DCA indicated that the hospital stay extension model showed good performance in the training and validation groups. Conclusion To identify patients' risk factors early, medical teams need to plan a patient's rehabilitation path as a whole. Its advantages lie in better resource allocation, maximizing medical resources, improving the functional recovery of patients, and reducing the overall cost of hospital stay and surgery, and will help clinicians in the future.

Abstract
INTRODUCTION The safety and benefits of single stage bilateral total knee arthroplasty (SSBTKA) among older patients as compared to unilateral TKA remains controversial. This study aimed to evaluate the influence of age and comorbidities on complications and early outcomes for unilateral and BTKA in patients over and under 70 years of age. MATERIALS AND METHODS This prospective study compared postoperative complications and early patient-reported outcomes at 6 weeks of 142 unilateral TKA patients (N = 75, ≤ 70; N = 67, > 70) and 89 SSBTKA patients (N = 48, ≤ 70; N = 41, > 70). Patients completed the KOOS JR and PROMIS Global Mental (GMH) and Global Physical Health (GPH) surveys. Knee Society Scores for Knee (KSS-K) and Function (KSS-F) were completed in the clinic. Parametric tests were performed for comparisons of unilateral and BTKA outcomes and complications for patients over and under 70. RESULTS While patient demographics were similar, patients > 70 had more comorbidities than patients ≤ 70 (p < 0.004). There were no significant differences in postoperative complications or readmissions between age groups or procedures. Unilateral TKA patients > 70 had significantly lower pre- (p < 0.001) and post-operative (p = 0.011) KSS-F scores compared to those ≤ 70. SSBTKA patients > 70 had significantly higher preoperative GMH (p = 0.029), postoperative KSS-K (p = 0.027), KOOS JR scores (p = 0.039) and satisfaction (p = 0.048) compared to those ≤ 70. CONCLUSION Age did not influence the risk of early postoperative complications. Additionally, the greater improvements in KOOS JR and higher patient satisfaction for SSBTKA patients > 70 suggests that SSBTKA may meet elderly patient expectations and should not necessarily be discouraged due to safety concerns.

Abstract
» Bilateral total knee arthroplasty (BTKA) is an effective surgical treatment for bilateral knee arthritis and can be performed as a simultaneous surgery under a single anesthetic setting or as staged surgeries on separate days. » Appropriate patient selection is important for simultaneous BTKA with several factors coming into consideration such as age, comorbidities, work status, and home support, among others. » While simultaneous BTKA is safe when performed on appropriately selected patients, current evidence suggests that the risk of complications after simultaneous BTKA remains higher than for staged BTKA. » When staged surgery is preferred, current evidence indicates that complication risks are minimized if the 2 knees are staged at least 3 months apart. » Simultaneous BTKA is the economically advantageous treatment option relative to staged BTKA, primarily because of shorter total operative time and total hospital stay.

Abstract
INTRODUCTION Controversy exists regarding the safety of simultaneous bilateral total knee arthroplasty (TKA) versus two TKA procedures staged months apart in patients with bilateral knee arthritis. Here, we investigated a third option: bilateral TKA staged 1 week apart. In this study, we examined the rate of complications in patients undergoing bilateral TKA staged at 1 week compared with longer time intervals. METHODS A retrospective review of 351 consecutive patients undergoing bilateral TKA at our institution was conducted. Patients underwent a 1-week staged bilateral procedure with planned interim transfer to a subacute rehabilitation facility (short-staged) or two separate unilateral TKA procedures within 1 year (long-staged). Binary logistic regression was used to compare outcomes while controlling for year of surgery, patient age, body mass index, and Charlson Comorbidity Index. RESULTS Two hundred four short-staged and 147 long-staged bilateral TKA patients were included. The average interval between procedures in long-staged patients was 200.9 ± 95.9 days. Patients undergoing short-staged TKA had a higher Charlson Comorbidity Index (3.0 ± 1.5 versus 2.6 ± 1.5, P = 0.017) with no difference in preoperative hemoglobin ( P = 0.285) or body mass index ( P = 0.486). Regression analysis demonstrated that short-staged patients had a higher likelihood of requiring a blood transfusion (odds ratio 4.015, P = 0.005) but were less likely to return to the emergency department within 90 days (odds ratio 0.247, P = 0.001). No difference was observed in short-term complications ( P = 0.100), 90-day readmissions ( P = 0.250), or 1-year complications ( P = 0.418) between the groups. CONCLUSION Bilateral TKA staged at a 1-week interval is safe with a comparable complication rate with delayed staged TKA, but allows for a faster total recovery time. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND The lifetime risk of developing symptomatic knee osteoarthritis (OA) is estimated to be 45%, with up to two thirds of patients presenting with bilateral knee symptoms. Patients presenting with end stage bilateral knee OA may benefit from single anaesthetic bilateral total knee replacement (SABTKR). Our study aim was to compare the outcomes of SABTKR with unilateral total knee arthroplasty (TKA) in a single surgeon series over a 20 year period. METHODS We performed a retrospective review of a single surgeon's data from the New Zealand Joint Registry (NZJR) over a 20-year period from January 1999 to December 2018. This review reports on patient demographics, functional outcomes, revision rates and mortality rates. RESULTS 1225 total knee replacements were performed by the senior author (995 TKAs and 115 patients underwent SABTKRs) over the 20 year period reviewed. The mean ages of the TKA and SABTKR groups were 67.7 and 66.7 years, respectively. There was 16.9% mortality rate for the TKA group versus 7.8% in SABTKR group. There were no revisions in the SABTKR group versus 17 revisions in the TKA group representing a revision rate of 0.23/100 component years which can be viewed against a 20 year revision rate of 0.48/100 component years (p < 0.05) for all comers in the NZJR. CONCLUSION This NZJR study demonstrates excellent medium term survival outcomes for selected patients having simultaneous bilateral total knee replacements.

Abstract
BACKGROUND Simultaneous bilateral total knee arthroplasty (BTKA) is associated with a higher risk but can be perceived to afford faster improvement and mitigated costs versus staged BTKA. We aimed to explore (1) health care utilization, (2) surgical supply costs of simultaneous BTKA; and (3) 1-year improvement in patient-reported pain, function, and quality of life (QOL) versus staged BTKA. METHODS A prospective cohort of 198 simultaneous and 625 staged BTKAs was obtained (2016-2020). Simultaneous BTKA cohort was propensity score-matched (1:2) to a similar group of staged patients (simultaneous = 198 versus staged = 396). Outcomes included length of stay, discharge disposition, 90-day readmission, 1-year reoperation, surgical episode supply cost, Knee Injury and Osteoarthritis Outcome Score (KOOS)-pain, KOOS-Physical Function Short Form, and KOOS-QOL. Rates of attaining minimal clinically important difference and Patient Acceptable Symptomatic State were calculated. RESULTS Compared to both staged BTKA surgeries combined, simultaneous BTKA demonstrated shorter median net length of stay (2.00 [2.00, 3.00] days versus 2.00 [2.00, 4.00] days; P < .001) but higher rates of nonhome discharge (n = 56 [28.3%] versus n = 32 [4.04%]; P < .001), 90-day readmission (n = 20 [10.1%] versus n = 48 [6.06%]; P = .047) and similar reoperation rates (P = .44). Simultaneous BTKA afforded slight reduction in net surgical cost compared to that of both staged BTKAs combined ($643; P = .028). There was no significant difference in 1-year improvement and minimal clinically important difference attainment rates with simultaneous versus staged BTKA for KOOS-pain (P = .137 and P = .99), KOOS-QOL (P = .095 and P = .81), or KOOS-Physical Function Short Form (P = .75 and P = .49, respectively) or Patient Acceptable Symptomatic State (P = .12). CONCLUSION Staged BTKA is associated with similar 1-year pain, function, and QOL at a better safety profile and minimal surgical supply cost increase compared to simultaneous BTKA.

Simultaneous Bilateral Total Knee Arthroplasty in Elderly: Are There Factors that Can Influence Safety and Clinical Outcome? Adv Orthop 2022; 2022:1989822. [PMID: 36046489 PMCID: PMC9420611 DOI: 10.1155/2022/1989822] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Revised: 07/25/2022] [Accepted: 07/30/2022] [Indexed: 11/18/2022] Open
Abstract
Objective The aim of this study was to look for preoperative patients' related factors correlating with worse clinical outcomes in a cohort of elderly patients undergoing simultaneous bilateral total knee arthroplasty (SiBTKA) to search for risk factors, which may influence clinical outcomes and safety. Subjects and Methods. The hospital database was mined searching for patients older than 70 years that underwent SiBTKA for severe bilateral knee osteoarthritis (OA) between 2012 and 2016. Preoperative clinical information, Oxford Knee Score (OKS), and Knee Injury and Osteoarthritis Outcome Score (KOOS) prior to surgery were recorded. The OKS and the KOOS were submitted again after a minimum of 5 years of follow-up (FU). Results An improvement was observed in all clinical scores at last FU. The major complication rate was 5.4%. No patients' clinical data showed correlation with perioperative complications or need for transfusions. Functional scores at the last FU were negatively affected by age at surgery and positively affected by preoperative clinical scores. Discussion. In the setting of severe symptomatic bilateral knee OA, SiBTKA seems to be effective in improving symptoms at midterm follow-up, with acceptable rates of perioperative complications in patients older than 70. Higher age at surgery and lower preoperative functional scores are associated with worse clinical outcomes at FU. This could assist surgeons in advising patients that delay of surgical treatment could worsen outcomes.

Abstract
BACKGROUND Published comparisons between bilateral and unilateral total knee arthroplasties (TKAs) remain biased, as most patients undergoing bilateral TKA are prescreened and healthier than average patients having unilateral procedures. Our objectives were to compare postoperative complications and resource utilization of patients having simultaneous bilateral TKAs with similar patients having unilateral procedures. METHODS The Nationwide Inpatient Sample (NIS) database was used to identify patients undergoing primary elective TKA from 2002 to 2011. A total of 4,445,263 patients were identified. Of these, 190,783 (4%) were having same-day bilateral procedures. Patients with staged bilateral TKA during the same hospitalization were excluded. Complications and costs were compared to a matched cohort of patients having unilateral procedures. This cohort was matched based on age, gender, and 30 comorbid-defined elements in the NIS. RESULTS A total of 172,366 (90%) simultaneous bilateral procedures were matched 1:1 to patients with unilateral procedures for the adjusted analysis. Patients with bilateral procedures were at an increased risk for many complications including postoperative anemia (OR: 2.3; 95% CI: 2.2-2.3, P < .001), cardiac (OR: 2.1; 95% CI: 2.0-2.3, P < .001), and inhospital mortality (OR: 3.3; 95% CI: 2.6-4.3). These patients also incurred in higher hospital costs ($19,343 vs $12,852, P < .001) and were discharged more commonly to a rehabilitation facility (70% vs 32%, P < .001). CONCLUSION Patients undergoing simultaneous bilateral TKA are at an increased risk of developing important postoperative complications and mortality compared with unilateral cases. These data highlight the importance of patient selection and optimization for bilateral TKA and potential cost savings.

Simultaneous bilateral total knee arthroplasty has higher in-hospital complications than both staged surgeries: a nationwide propensity score matched analysis of 38,764 cases. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2022; 33:1057-1066.

Abstract
PURPOSE To investigate (1) healthcare utilization, (2) in-hospital metrics and (3) total in-hospital costs associated with simultaneous versus staged BTKA while evaluating staged BTKA as a single process consisting of two combined episodes. METHODS The national readmissions database was reviewed for simultaneous and staged (two primary unilateral TKAs12 months apart) BTKA patients (2016-2017). A total of 19,382 simultaneous BTKAs were identified, and propensity score matched (1:1) to staged BTKA patients (19,382 patients; 38,764 surgeries) based on demographics, comorbidities, and socioeconomic determinants. Outcomes included healthcare utilization [length of stay (LOS) and discharge disposition], in-hospital periprosthetic fractures, non-mechanical complications, and costs. Staged BTKA was evaluated as one process consisting of two episodes. For each staged patient, continuous outcomes were evaluated via the sum of both episodes. Categorical outcomes were added, and percents were expressed relative to total number of surgeries (n = 38,764). RESULTS Simultaneous BTKA had longer LOS (5.0 days ± 4.7 vs. 4.5 days ± 3.5; p < 0.001), higher non-home discharge [36.9% (n = 7150/19,382) vs. 13.6% (n = 5451/38,764)], in-hospital periprosthetic fractures [0.13% (26/19,382) vs. 0.08% (31/38,764); p = 0.049], any non-mechanical complication [33.76% (6543/19,382) vs.15.93% (6177/38,764); p < 0.0001], hematoma/seroma formation [0.11% (22/19,382) vs. 0.05% (20/38,764); p = 0.0088], wound disruption [0.08% (16/19,382) vs. 0.04% (16/38,764); p = 0.0454], and any infection [1.13% (219/19,382) vs. 0.50% (194/38,764); p < 0.0001]. Average in-hospital costs for the two staged BTKA episodes combined were $5006 higher than those of simultaneous BTKA ($28,196 ± $18,488 vs. $33,202 ± $15,240; p < 0.001). CONCLUSION Simultaneous BTKA had higher healthcare utilization and in-hospital complications than both episodes of staged BTKA combined, with a minimal in-hospital cost savings. Future studies are warranted to further explore patient selection who would benefit from BTKA.

[PMID: 35176554 DOI: 10.1016/j.knee.2022.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 12/21/2021] [Accepted: 02/01/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Long-term follow-up after total knee arthroplasty (TKA) is crucial to providing survivorship updates on available TKA implants to guide patient expectations when undergoing TKA. The purpose of this study was to compare implant survivorship between patients undergoing primary single, simultaneous bilateral, and staged bilateral TKA with 15-year minimum follow-up. METHODS This retrospective study included 826 patients (n = 1089) who underwent primary single (n = 454), simultaneous bilateral (n = 266), or staged bilateral (n = 369) TKA using a single TKA system by a single surgeon from 1991-2005 with 15-year minimum follow-up. Demographics, clinical variables, and surgical outcomes were collected and compared using Student's t-test, chi-squared tests, or Kaplan-Meier analyses. Reoperation was defined as all surgeries performed on the knee after the index procedure; revision TKA was defined as complete implant exchange. p < 0.05 significant. RESULTS Patients in the staged TKA cohort were younger (65.4 years = staged, 67.8 = simultaneous, 67.1 = single, p < 0.019). Women were less likely to receive simultaneous TKAs (22 %vs.29%, p < 0.001). Postoperative range of motion was similar (116.8° = simultaneous, 114.9° = staged, 114.8° = single, p = 0.11). Overall 15-year implant survival based on revision TKA was similar (97.7% = simultaneous, 97.2% = staged, 96.7% = single, p = 0.45). The estimated 15-year reoperation rate was 7.0% (95% CI, 5.5-8.7%). Reoperations were secondary to infection (35.5%), implant wear (26.3%), arthrofibrosis (18.4%), traumatic injuries (10.5%), pain (6.6%), pathologic lesion (1.3%), and avascular necrosis (1.3%). CONCLUSION This study demonstrated a high implant survival rate of 95-97% at 20-years after primary single, staged bilateral and simultaneous bilateral TKA. Furthermore, simultaneous bilateral TKAs exhibited similar range of motion, implant survival, and rates of reoperation to staged bilateral and single TKA.

Abstract
AIMS This study aimed to evaluate whether an enhanced recovery protocol (ERP) for arthroplasty established during the COVID-19 pandemic at a safety net hospital can be associated with a decrease in hospital length of stay (LOS) and an increase in same-day discharges (SDDs) without increasing acute adverse events. METHODS A retrospective review of 124 consecutive primary arthroplasty procedures performed after resuming elective procedures on 11 May 2020 were compared to the previous 124 consecutive patients treated prior to 17 March 2020, at a single urban safety net hospital. Revision arthroplasty and patients with < 90-day follow-up were excluded. The primary outcome measures were hospital LOS and the number of SDDs. Secondary outcome measures included 90-day complications, 90-day readmissions, and 30day emergency department (ED) visits. RESULTS The mean LOS was significantly reduced from 2.02 days (SD 0.80) in the pre-COVID cohort to 1.03 days (SD 0.65) in the post-COVID cohort (p < 0.001). No patients in the pre-COVID group were discharged on the day of surgery compared to 60 patients (48.4%) in the post-COVID group (p < 0.001). There were no significant differences in 90-day complications (13.7% (n = 17) vs 9.7% (n = 12); p = 0.429), 30-day ED visits (1.6% (n = 2) vs 3.2% (n = 4); p = 0.683), or 90-day readmissions (2.4% (n = 3) vs 1.6% (n = 2); p = 1.000) between the pre-COVID and post-COVID groups, respectively. CONCLUSION Through use of an ERP, arthroplasty procedures were successfully resumed at a safety net hospital with a shorter LOS and increased SDDs without a difference in acute adverse events. The resulting increase in healthcare value therefore may be considered a 'silver lining' to the moratorium on elective arthroplasty during the COVID-19 pandemic. These improved efficiencies are expected to continue in post-pandemic era. Cite this article: Bone Jt Open 2021;2(10):871-878.

Abstract
Blount disease is an acquired, asymmetrical disorder of proximal tibial growth that results in a complex three-dimensional proximal tibial deformity, with tibial varus being the dominating feature. Although the exact pathophysiology is unknown, Blount disease is separated into 2 clinical variants, infantile and adolescent, based on the onset of symptoms occurring before or after the age of 10 years. If recognized and treated early, affected patients generally have a favorable prognosis; however, if neglected, it can lead to progressive malalignment and premature osteoarthritis. We present a patient with bilateral neglected Blount disease who underwent successful bilateral total knee arthroplasty performed in a staged fashion using a gap balancing technique with constrained condylar knee implants.

An opioid-sparing protocol with intravenous parecoxib can effectively reduce morphine consumption after simultaneous bilateral total knee arthroplasty. Sci Rep 2021; 11:7362. [PMID: 33795787 PMCID: PMC8016913 DOI: 10.1038/s41598-021-86826-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2020] [Accepted: 03/19/2021] [Indexed: 11/09/2022] Open
Abstract
Multimodal pain management protocol effectively relieves pain following simultaneous bilateral total knee arthroplasty (SBTKA) but is associated with administration of large amounts of opioids in the perioperative period. In this prospective, randomized, assessor-blinded, single-surgeon clinical trial, the goal was to validate the efficacy of an opioid-sparing protocol for SBTKA with a reduced opioid dose, while achieving similar pain relief with few adverse events. Fifty-six patients who had undergone SBTKA were randomly allocated to receive either an opioid-sparing or opioid-based protocol. The primary outcome parameters were visual analogue scale (VAS) scores at rest, with movement, and cumulative morphine dose, through time. Secondary outcome parameters included drug-related adverse events and range of motion with continuous passive motion device, through time. In the opioid-sparing group, a lower VAS score with movement at postoperative 24 and 72 h was observed compared with the opioid-based group, but the difference did not reach the minimal clinically importance difference. A reduced cumulative morphine dose was noted in the opioid-sparing group at postoperative 24, 48 and 72 h. In conclusion, the opioid-sparing protocol may be used as an alternative modality for pain management following SBTKA. Similar pain relief effects may be achieved utilizing a reduced cumulative opioid dose, with few opioid related adverse events.
