Project description:PurposeThe purpose of this study was to evaluate whether the combination of preoperative planning software combined with arithmetic hip-knee-ankle angle (aHKA) can help patients who underwent uni-compartmental knee arthroplasty (UKA) recover the constitutional alignment of the lower limb, obtain a better prosthetic position, and achieve better early patient-reported outcome measurements (PROMs).MethodsA total of 150 patients who underwent UKA (planning group: 50 patients using the preoperative planning software; conventional group: 100 patients using the conventional method) were included in the study. The aHKA was defined as 180° + mechanical medial proximal tibial angle (MPTA) - mechanical distal lateral femoral angle (LDFA). All patients in the planning group underwent UKA according to the planning software with the planned lower limb alignment of aHKA. All patients were divided into three groups: constitutional alignment group (postoperative HKA (post-HKA): aHKA ± 2.0°); overcorrection group (post-HKA > aHKA + 2.0°); under-correction group (post-HKA < aHKA - 2.0°). Comparisons between the planning and conventional groups were conducted: (1) the proportion of post-HKA restored to constitutional alignment group; (2) the postoperative prosthesis position parameter based on the guideline of the Oxford group; (3) the American Knee Society scores (KSS) at six months after surgery.ResultsThe proportion of the constitutional alignment group in the planning group was higher than that in the conventional group (86% vs. 66%) (p = 0.033). There was no significant difference in postoperative prosthesis position parameters between the two groups. No significant difference was found between the KSS clinical score (91.02 ± 4.20 vs. 90.61 ± 4.24) and KSS functional score (86.10 ± 7.23 vs. 84.30 ± 6.82) in six months after surgery between the planning and conventional groups.ConclusionPatients who underwent UKA using preoperative planning software in combination with aHKA were able to recover a higher proportion of the constitutional alignment than those with the conventional method. In addition, the planning group could achieve similar postoperative prosthesis position and short-term PROMs compared to the conventional group.Clinical trial numberNot applicable.

Project description:BackgroundAlthough telemedicine visits were essential and adopted by providers and patients alike, few studies have been conducted evaluating orthopedic patient perception of the care delivered during these visits. To our knowledge, no study has evaluated specific factors that affected patient satisfaction with telemedicine and the receptiveness to continue virtual visits post COVID-19 in total joint arthroplasty (TJA) patients. Thus, the purposes of our study are to determine the following: (1) patient satisfaction with using TJA telemedicine services, (2) whether patient characteristics might be associated with satisfaction, and (3) whether virtual clinic visits may be used post-COVID-19.MethodsA prospective, cross-sectional survey study was completed by 126 TJA patients who participated in telemedicine visits with TJA surgeons from May 1, 2020 to August 31, 2020. The survey consisted of questions regarding demographics, satisfaction, and telemedicine experiences.ResultsOne hundred one (80.2%) patients were satisfied with their telemedicine visit, with patients <80 years old (P = .008) and those with a longer commute time (P = .01) being more satisfied P = .01. There was a significant preference for in-person visits when meeting arthroplasty surgeons for the first time (P < .001), but patients were equally amenable to follow-up telemedicine visits once there was an established relationship with the surgeon.ConclusionYounger patients, patients with longer commute distances, and patients who had established relationships with their provider expressed higher satisfaction with telemedicine arthroplasty visits. Although >80% of patients were satisfied with their telemedicine visit, an established patient-provider relationship may be integral to the success of an arthroplasty telemedicine practice.

Project description:BackgroundCOVID-19 was declared as a pandemic in March 2020. Government of India declared a countrywide lockdown on 24 March 2020. All elective surgeries including Hip and Knee arthroplasty were postponed in view of pandemic. Gradually cases were resumed after stepwise unlock measures. The aim of this study is to assess how hip and knee arthroplasty surgeries were affected during first wave of pandemic, and how situation was tackled by an arthroplasty unit of a tertiary-care hospital in India.MethodsThis study was a single-centre retrospective observational study. Data pertaining to patient demographic details, surgery, preoperative screening for COVID-19, duration of hospital stay, and post-op 30-day complications were collected from hospital records and analyzed. These data were compared with 2019 data.ResultsThere was significant decrease (88.45%) in total number of hip and knee arthroplasty cases between March 2020 and November 2020 as compared to the same duration in 2019. 30-day mortality was only 2 deaths both who died due to COVID-19-related complications. Duration of stay in hospital and post-operative complications were not statistically and significantly affected. There was a statistically significant increase in tourniquet time compared to the previous year. If deaths due to COVID-19 are excluded, there was statistically no significance difference in 30-day mortality rate.ConclusionFollowing strict local policy for patient selection and reducing the number of post-operative patient visits to the hospital allowed us to perform hip and knee arthroplasty safely with minimum COVID-19-related mortality and morbidity.Supplementary informationThe online version contains supplementary material available at 10.1007/s43465-023-00930-6.

Project description:BackgroundThe SARS-CoV-2 (COVID-19) pandemic caused a massive disruption in elective arthroplasty practice in the United States that to date has not been quantified. We sought to determine the impact of COVID-19 on arthroplasty volumes in the United States, how this varied across the country, and the resultant financial implications.MethodsWe conducted a retrospective analysis of Medicare fee-for-service beneficiaries undergoing primary and revision total knee arthroplasty (TKA) and total hip arthroplasty (THA) from January 1st through March 31st, 2020 with 74,080 TKAs and 54,975 THAs identified. We calculated the percent drop in average daily cases from before and after March 18, 2020. We then examined variation across states in arthroplasty case volumes as it related to reported COVID-19 cases, the impact of COVID-19 on length of stay and percentage of patients discharged home. Finally, we calculated the revenue impact on hospitals and surgeons.ResultsThere was a steep decline in TKA and THA volumes in mid-March of 94% and 92%, respectively. There was a significant variation for arthroplasty case volumes across states. We found minimal change in length of stay except for primary THAs with fracture going from 5 + days to 4 days. We saw an increasing trend in discharge to home with the greatest effect in primary THAs with fracture. The total daily hospital Medicare revenue for arthroplasty declined by 87% and surgeon revenue decreased by 85%.ConclusionThe beginning of the COVID-19 pandemic caused a significant decrease in arthroplasty volumes in the Medicare population with a resultant substantial revenue loss for hospitals and surgeons.

Project description:BackgroundUnder-represented minorities and those with noncommercial insurance have higher medical comorbidities and complications following elective total joint arthroplasty (TJA). In an effort to bridge this gap, our center implemented a preoperative optimization protocol for TJA in a Medicaid Clinic (Clinic). The purpose of this study is to assess the effectiveness of that protocol and highlight challenges associated with caring for this patient population.MethodsThis retrospective analysis included 117 patients undergoing TJA between January 2015 and January 2020. In 2015, the protocol was implemented as a mandatory practice prior to TJA. A contemporary control cohort from the private office was also analyzed. Patient demographics, American Society of Anesthesiologists score, and postoperative complications were collected.ResultsWithin the clinic group, 52.5% (62) patients identified as Hispanic with 46.6% (55) Spanish-speaking as primary language, compared to 9.3% (11) and 8.5% (10) in the office group (P = .0001), respectively. Clinic group patients were significantly more likely to experience a complication compared to office patients (20 vs 7, respectively). There was no difference in complication or reoperation rate between clinic patients who underwent the optimization protocol and those who did not.ConclusionsThe findings from this study highlight the demographic and comorbidities profile of an underserved population, and report on results of a quality improvement initiative among that population, which failed to improve postoperative outcomes. These results underscore the need for further study in this population to improve outcomes and health equity.

Project description:Total knee arthroplasty (TKA) in the setting of previous hip fusion is rare with a paucity of evidence in the orthopaedic literature. Traditionally, TKA is performed supine, with the aid of knee-positioning devices allowing for hip flexion and range of motion of the knee to facilitate ease of surgical intervention. However, TKA using traditional positioning would not be possible in the presence of ipsilateral hip arthrodesis preventing hip motion. This case report describes a TKA performed for a 72-year-old woman with end-stage osteoarthritis of the right knee, ipsilateral hip arthrodesis, and leg-length discrepancy as the sequelae of slipped capital femoral epiphysis. We describe novel surgical positioning to be used to facilitate TKA in the absence of ipsilateral hip motion with bed modifications and the use of an extremity positioning device.

Project description:BackgroundIn an effort to help combat the COVID-19 pandemic and preserve essential health care resources, starting in mid-March 2020, surgeons have been instructed to only perform essential surgical procedures. The vast majority of hip and knee arthroplasty surgery does not meet the definition of essential surgery. This study estimated the number of arthroplasty procedures that would be canceled because of these important restrictions.MethodsThe US hip and knee arthroplasty procedure volume projections for 2020 were estimated from four recently published studies. Data from the American Joint Replacement Registry were utilized to determine what percentage of these cases would be considered nonessential surgery. Monthly and weekly estimates of nonessential hip and knee arthroplasty procedures that would have occurred had there not been any restrictions due to COVID-19 were calculated.ResultsAfter excluding essential procedures, it was estimated that approximately 30,000 primary and 3000 revision hip and knee arthroplasty procedures will be canceled each week while COVID-19 restrictions regarding nonessential surgery are in place. If only 50% of nonessential cases were actually canceled across the United States, that would still result in the cancellation of 15,001 primary and 1435 revision hip and knee arthroplasty procedures per week while restrictions are in place.ConclusionThis study highlights the profound impact COVID-19 is having on our current hip and knee arthroplasty volume. The large number of cases canceled because of COVID-19 translates into major financial losses for health care institutions and may have a profound impact on our patients.

Project description:ImportanceThe optimal pharmacologic thromboprophylaxis agent after total hip and total knee arthroplasty is uncertain and consensus is lacking. Quantifying the risk of postoperative venous thromboembolism (VTE) and bleeding and evaluating comparative effectiveness and safety of the thromboprophylaxis strategies can inform care.ObjectiveTo quantify risk factors for postoperative VTE and bleeding and compare patient outcomes among pharmacological thromboprophylaxis agents used after total hip and knee arthroplasty.Design, setting, and participantsThis retrospective cohort study used data from a large health care claims database. Participants included patients in the United States with hip or knee arthroplasty and continuous insurance enrollment 3 months prior to and following their surgical procedure. Patients were excluded if they received anticoagulation before surgery, received no postsurgical pharmacological thromboprophylaxis, or had multiple postsurgery thromboprophylactic agents. In a propensity-matched analysis, patients receiving a direct oral anticoagulant (DOAC) were matched with those receiving aspirin.ExposuresAspirin, apixaban, rivaroxaban, enoxaparin, or warfarin.Main outcomes and measuresThe primary outcome was 30-day cumulative incidence of postdischarge VTE. Other outcomes included postdischarge bleeding.ResultsAmong 29 264 patients included in the final cohort, 17 040 (58.2%) were female, 27 897 (95.2%) had inpatient admissions with median (IQR) length of stay of 2 (1-2) days, 10 948 (37.4%) underwent total hip arthroplasty, 18 316 (62.6%) underwent total knee arthroplasty; and median (IQR) age was 59 (55-63) years. At 30 days, cumulative incidence of VTE was 1.19% (95% CI, 1.06%-1.32%) and cumulative incidence of bleeding was 3.43% (95% CI, 3.22%-3.64%). In the multivariate analysis, leading risk factors associated with increased VTE risk included prior VTE history (odds ratio [OR], 5.94 [95% CI, 4.29-8.24]), a hereditary hypercoagulable state (OR, 2.64 [95% CI, 1.32-5.28]), knee arthroplasty (OR, 1.65 [95% CI, 1.29-2.10]), and male sex (OR, 1.34 [95% CI, 1.08-1.67]). In a propensity-matched cohort of 7844 DOAC-aspirin pairs, there was no significant difference in the risk of VTE in the first 30 days after the surgical procedure (OR, 1.14 [95% CI, 0.82-1.59]), but postoperative bleeding was more frequent in patients receiving DOACs (OR, 1.36 [95% CI, 1.13-1.62]).Conclusions and relevanceIn this cohort study of patients who underwent total hip or total knee arthroplasty, underlying patient risk factors, but not choice of aspirin or DOAC, were associated with postsurgical VTE. Postoperative bleeding rates were lower in patients prescribed aspirin. These results suggest that thromboprophylaxis strategies should be patient-centric and tailored to individual risk of thrombosis and bleeding.

Project description:Ischaemic preconditioning is a method of protecting tissue against ischaemia-reperfusion injury. It is an innate protective mechanism that increases a tissue's tolerance to prolonged ischaemia when it is first subjected to short burst of ischaemia and reperfusion. It is thought to provide this protection by increasing the tissue's tolerance to ischaemia, therby reducing oxidative stress, inflammation and apoptosis in the preconditioned tissue. We used microarrays to investigate the genomic response induced by ischaemic preconditioning in muscle biopsies taken from the operative leg of total knee arthroplasty patients in order to gain insight into the ischaemic preconditioning mechanism. Patients undergoing primary knee arthroplasty were randomised to control and treatment (ischaemic preconditioning) groups. Patients in the treatment group received a preconditioning stimulus immediately prior to surgery. The ischaemic preconditioning stimulus consisted of three five-minute periods of tourniquet insufflation on the lower operative limb, interrupted by five minute periods of reperfusion. All patients had a tourniquet applied to the lower limb after the administration of spinal anaesthesia, as per normal protocol for knee arthroplasty surgery. Muscle biopsies were taken from the quadriceps muscle of the operative knee at the immediate onset of surgery (T0) and at 1 hour into surgery (T1). Total RNA was extracted from biospies of four control and four treatment patients and hybridised to the Affymetrix Human U133 2.0 chip.
