Introduction: Modern primary cementless total knee arthroplasty (TKA) is increasingly popular, but there is limited evidence on its benefits, early complications, and failures. Purpose: We sought to evaluate operative time, early survivorship, and outcomes of cementless versus cemented TKA of the same design. Methods: As part of this single-center, multisurgeon, retrospective cohort study, we reviewed 598 primary, unilateral TKAs (170 cementless, 428 cemented) of the same design from 2016 to 2018. The cementless cohort was younger (63 vs 67 years) and had more cruciate-retaining implants (17% vs 12%) compared with the cemented cohort. We compared operative time, length of stay, and complications. Survivorship curves were generated via the Kaplan-Meier method. Results: Patients with cementless TKA (using the Triathlon implant, Stryker) had a 24% reduction in operative time (83 vs 109 minutes) but similar length of stay compared with those with cemented TKA (57 vs 61 hours). Cementless TKA had a higher rate of postoperative manipulation for stiffness compared with cemented TKA (8% vs 3%), but there were notable demographic differences between the cohorts. Despite 2 cases (1%) of early cementless tibial aseptic loosening requiring component revision compared with none in the cemented cohort, there was no difference in revision-free survivorship at 2 years (96% and 98%, respectively). Conclusion: This retrospective cohort study found that cementless TKA had a 24% reduction in operative time compared with cemented TKA and similar short-term survivorship. There was a slightly higher rate of aseptic revision and manipulation in the cementless cohort. Further study is warranted on the long-term durability of cemented and cementless TKAs to determine if cementless fixation proves more durable in the midterm to long term.
现代初级无骨水泥全膝关节置换术(TKA)越来越受欢迎，但关于其益处、早期并发症和失败的证据有限。目的:我们试图评估相同设计的无骨水泥TKA与骨水泥TKA的手术时间、早期生存率和结果。方法:作为这项单中心、多外科医生、回顾性队列研究的一部分，我们回顾了2016年至2018年598例相同设计的原发性单侧tka(170例无骨水泥，428例骨水泥)。与骨水泥组相比，无骨水泥组更年轻(63岁vs 67岁)，并且有更多的保留种植体(17% vs 12%)。我们比较了手术时间、住院时间和并发症。生存曲线通过Kaplan-Meier法生成。结果:无骨水泥TKA患者(使用Triathlon植入物，Stryker)手术时间减少24%(83分钟对109分钟)，但住院时间与骨水泥TKA患者相似(57小时对61小时)。与骨水泥TKA相比，无骨水泥TKA具有更高的术后僵硬操作率(8% vs 3%)，但队列之间存在显著的人口统计学差异。尽管有2例(1%)早期无骨水泥胫骨无菌性松动需要翻修，而在骨水泥组中没有一例需要翻修，但2年无翻修生存率没有差异(分别为96%和98%)。结论:这项回顾性队列研究发现，与骨水泥TKA相比，无骨水泥TKA的手术时间减少了24%，短期生存期相似。在无骨水泥组中，无菌翻修和操作的比例略高。需要进一步研究骨水泥和无骨水泥tka的长期耐久性，以确定无骨水泥固定是否在中期到长期内更持久。

Background: Proximal tibiofibular joint (PTFJ) ganglion cyst is a rare condition with a high rate of recurrence. Optimal treatment has not yet been determined. Purpose: We aimed to answer the following questions: (1) What are the most common treatments for PTFJ cysts and their associated recurrence rates? (2) What are the risk factors for failure to completely recover from symptoms? (3) What are the risk factors for cyst recurrence? Methods: A systematic review was performed using PubMed and EMBASE databases. Studies were assessed for inclusion and exclusion criteria, and quality analysis following the PRISMA guidelines. Information on demographic, clinical, and treatment characteristics was retrieved from articles. Results: The most common surgical treatment was cyst excision (75.3%). Patients with PTFJ arthrodesis and PTFJ resection had the lowest recurrence rates at 0% and 4.4%, respectively. Complete recovery from symptoms was more common in PTFJ resection (70.8%) than in PTFJ arthrodesis (42.9%). Risk factors for failure to achieve complete recovery from symptoms included intraneural compromise (odds ratio [OR] = 3.93), cyst recurrence (OR = 6.04), and being a contact sports athlete (OR = 9.85). Ligation of the articular branch of the peroneal nerve (PN) was a protective factor (OR = 0.29). A history of knee arthritis was the most important risk factor for cyst recurrence (OR = 20.01); PTFJ arthrodesis was a protective factor (OR = 0.04). Conclusion: This systematic review of level-IV studies found PTFJ resection or arthrodesis to be the most effective treatment options. Intraneural compromise of the common peroneal nerve, cyst recurrence, and participation in contact sports are risk factors for incomplete symptom recovery, and ligation of the articular branch of the PN is a protective factor. Knee arthritis is a risk factor for cyst recurrence. More rigorous study is needed.

Background: Disparity in access to total hip arthroplasty (THA) is an internationally recognized phenomenon influenced by social and geographical factors. The Organisation for Economic Co-operation and Development (OECD) employs the utilization rates of THA to evaluate and compare healthcare utilization by its 37 country members, including Chile. Purpose: We sought to describe THA utilization rates in the elderly Chilean population and to compare it with data from other OECD countries. In addition, we sought to identify whether sociodemographic variables influence access to THA in Chile. Methods: We conducted a retrospective review of THA cases performed in Chile between 2016 and 2018 in patients aged 65 years and older in a large database regulated by the Ministry of Health; 8970 patients were included. Mean utilization rates (MURs) of THA within Chile’s 346 administrative-territorial divisions (called communes) were calculated. We analyzed associations between the communal MUR and poverty, rurality, insurance type, and geographical health administration dependency. Results: The national MUR of THA in the elderly population in Chile was 144/100,000 for the period studied. The median communal MUR was 107 (interquartile range [IQR]: 66–153). A lower MUR of THA was observed in communes with higher poverty levels, higher rurality, and a lower rates of private insurance. After negative binomial regression analysis, only rurality rate and geographical healthcare service dependency were associated with MUR. Conclusions: This retrospective database study suggests that the utilization of THA in Chile is unequal and well below the average of other OECD countries. Higher rates of rurality and administrative healthcare dependence (a geographical/administrative factor) were associated with disparities in access to THA within Chile.

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.

Background: Postoperative sagittal alignment has been shown to be associated with patient-reported outcome measures (PROMs) following open lumbar decompression procedures, although it is unknown whether preoperative sagittal imbalance affects clinical outcomes of minimally invasive surgical (MIS) decompression only surgery. Purpose: We sought to evaluate the impact of preoperative pelvic incidence-lumbar lordosis (PI-LL) imbalance on PROMs after MIS laminectomy for the treatment of neurogenic claudication symptoms. Methods: We conducted a retrospective cohort study of adult patients undergoing MIS laminectomy for degenerative lumbar spinal stenosis between April 2017 and April 2021 at a single institution. Of the 52 patients included (mean follow-up, 17 months) radiographs were taken prior to surgery and assessed for sagittal alignment parameters. Patients were grouped based on the preoperative PI-LL (balanced vs unbalanced). Changes in PROMs were compared between unbalanced PI-LL and balanced PI-LL groups. Minimal clinically important difference (MCID) for Oswestry Disability Index (ODI) was also assessed. Results: Of the 52 patients, 17 (32.7%) had unbalanced age-adjusted preoperative PI-LL. There was no significant difference found in PROMs between unbalanced and balanced PI-LL groups preoperatively or at final follow-up. Compared with those with unbalanced PI-LL, patients with balanced PI-LL were shown to have no added benefit in achieving MCID for ODI at long-term follow-up and no added benefit in the time to achieving MCID. Conclusion: These retrospective findings suggest that patients with unbalanced preoperative PI-LL may experience significant benefit in long-term clinical outcomes following MIS laminectomy, similarly to those with balanced PI-LL at baseline. The findings also suggest that the presence of sagittal imbalance preoperatively may not appreciably influence the long-term clinical outcomes following MIS laminectomy. Prospective study involving a larger population is warranted.

Background: Machine learning (ML) has emerged as a method to determine patient-specific risk for prolonged postoperative opioid use after orthopedic procedures. Purpose: We sought to analyze the efficacy and validity of ML algorithms in identifying patients who are at high risk for prolonged opioid use following orthopedic procedures. Methods: PubMed, EMBASE, and Web of Science Core Collection databases were queried for articles published prior to August 2021 for articles applying ML to predict prolonged postoperative opioid use following orthopedic surgeries. Features pertaining to patient demographics, surgical procedures, and ML algorithm performance were analyzed. Results: Ten studies met inclusion criteria: 4 spine, 3 knee, and 3 hip. Studies reported postoperative opioid use over 30 to 365 days and varied in defining prolonged use. Prolonged postsurgical opioid use frequency ranged from 4.3% to 40.9%. C-statistics for spine studies ranged from 0.70 to 0.81; for knee studies, 0.75 to 0.77; and for hip studies, 0.71 to 0.77. Brier scores for spine studies ranged from 0.039 to 0.076; for knee, 0.01 to 0.124; and for hip, 0.052 to 0.21. Seven articles reported calibration intercept (range: –0.02 to 0.16) and calibration slope (range: 0.88 to 1.08). Nine articles included a decision curve analysis. No investigations performed external validation. Thematic predictors of prolonged postoperative opioid use were preoperative opioid, benzodiazepine, or antidepressant use and extremes of age depending on procedure population. Conclusions: This systematic review found that ML algorithms created to predict risk for prolonged postoperative opioid use in orthopedic surgery patients demonstrate good discriminatory performance. The frequency and predictive features of prolonged postoperative opioid use identified were consistent with existing literature, although algorithms remain limited by a lack of external validation and imperfect adherence to predictive modeling guidelines.

Background: Mental health influences postoperative outcomes in orthopedic procedures. Increasing attention is being paid to this effect. Purpose: We sought to evaluate the effect of diagnosed depression, anxiety, or both on postoperative outcomes in patients who have undergone hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Methods: We conducted a retrospective cohort study of 289 patients aged 30 years or younger who underwent hip arthroscopy for FAIS at a single institution from January 2014 to June 2021. Univariate statistics were used to assess differences between patients diagnosed with depression, anxiety, or both, and those without these diagnoses. Differences included demographics, operative characteristics, and postoperative outcomes: duration of postanesthesia care unit (PACU) stay, PACU pain scores, complications, reoperations, postoperative injections, 90-day emergency department (ED) visits, and patient-reported outcome measures (PROMs). Multivariate analysis was used to evaluate risk factors for postoperative complications, including wound infection, documented reinjury, postoperative intra-articular hip injection, and any reoperation. Results: Patients diagnosed with depression, anxiety, or both were more likely to be older, female, and have a higher comorbidity burden. At the time of surgery, they were more likely to undergo concomitant procedures, including bursectomy and iliotibial band release. Postoperatively, they had longer PACU stays (90.5 vs 75.1 minutes) and higher first PACU pain scores (5.9 vs 4.6), as well as higher rates of postoperative injection (18.1 vs 9.2%), any reoperation (13.9% vs 4.6%), and revision hip arthroscopy (11.1% vs. 3.7%). Diagnoses of depression, anxiety, or both were independently predictive of any reoperation (odds ratio [OR] = 2.841) and revision hip arthroscopy (OR = 3.401). Conclusion: This retrospective cohort study found that, in patients undergoing hip arthroscopy for FAIS, there was an association between a diagnosis of depression, anxiety, or both, and increased comorbidities, higher first PACU pain scores, longer PACU stays, and increased rates of postoperative injection, any reoperation, or revision hip arthroscopy. Targeted interventions may improve outcomes, but further study is warranted.
背景:心理健康影响骨科手术后的预后。这种影响正受到越来越多的注意。目的:我们试图评估诊断为抑郁、焦虑或两者兼有对髋关节镜治疗股髋臼撞击综合征(FAIS)患者术后预后的影响。方法:我们对2014年1月至2021年6月在同一家机构接受FAIS髋关节镜检查的289例30岁及以下患者进行了回顾性队列研究。单变量统计用于评估被诊断为抑郁、焦虑或两者兼而有之的患者与没有这些诊断的患者之间的差异。差异包括人口统计学、手术特征和术后结果:麻醉后护理病房(PACU)住院时间、PACU疼痛评分、并发症、再手术、术后注射、90天急诊科(ED)就诊和患者报告的结果测量(PROMs)。多变量分析用于评估术后并发症的危险因素，包括伤口感染、记录的再损伤、术后髋关节关节内注射和任何再手术。结果:被诊断为抑郁、焦虑或两者兼而有之的患者更可能是老年人、女性，并且有更高的合并症负担。在手术时，他们更有可能接受伴随手术，包括滑囊切除术和髂胫束松解。术后患者PACU停留时间较长(90.5 vs 75.1分钟)，首次PACU疼痛评分较高(5.9 vs 4.6)，术后注射率较高(18.1 vs 9.2%)，再手术率较高(13.9% vs 4.6%)，髋关节镜翻修率较高(11.1% vs 3.7%)。诊断为抑郁、焦虑或两者兼而有之是再次手术(优势比[or] = 2.841)和翻修髋关节镜检查(or = 3.401)的独立预测因素。结论:这项回顾性队列研究发现，在因FAIS接受髋关节镜检查的患者中，抑郁、焦虑或两者兼有的诊断与合并症增加、首次PACU疼痛评分较高、PACU住院时间较长、术后注射、任何再手术或翻修髋关节镜检查的发生率增加有关。有针对性的干预可能会改善结果，但需要进一步的研究。

Background: Little is known about patients’ postoperative week-by-week progress after undergoing posterior approach total hip arthroplasty (THA) with regard to pain, function, return to work, and driving. Purpose: We sought to evaluate a large cohort of patients undergoing posterior approach THA with modified posterior hip precautions to better understand the trajectory of recovery. Methods: Patients at a single institution undergoing primary posterior approach THA by fellowship-trained arthroplasty surgeons were prospectively enrolled. Patient functional status and early rehabilitation recovery milestones were evaluated preoperatively and each week postoperatively for 6 weeks. Results: Of 312 patients who responded to weekly questionnaires, there were varying response rates per question. At 1 week after surgery, 15% (39/256) of respondents had returned to work, increasing to 57% (129/225) at week 6. At 6 weeks, 77% of patients (174/225) had returned to driving; 25% (56/225) were taking pain medication (including prescription opioids or nonsteroidal anti-inflammatory drugs); and 15% (34/225) were using assistive devices (down from 91%, 78%, 56%, 35%, and 27% at weeks 1, 2, 3, 4, and 5, respectively). Average postoperative Hip dysfunction and Osteoarthritis Outcome Score for Joint Replacement and Lower Extremity Functional Scale scores were significantly higher than preoperative scores. Respondents reported significantly less pain at each week postoperatively than the previous week. Conclusion: These findings suggest that there may be an expected pathway for recovery after posterior THA using perioperative pain protocols, modified postoperative precautions, and physical therapy protocols to improve patient outcomes after THA, with most patients returning to normal at 4 weeks. Defining the expected recovery timeline may help surgeons in counseling patients preoperatively and guiding their recovery.

Background: The American Academy of Orthopaedic Surgeons (AAOS) clinical practice guidelines (CPGs) note “strong” evidence that early and delayed mobilization protocols after small to medium arthroscopic rotator cuff repairs achieve similar rotator cuff healing rates. Purpose: We utilized the reverse fragility index (RFI) to assess the fragility of randomized controlled trials (RCTs) reporting no statistically significant difference in tendon re-tear rates after rotator cuff repair in those undergoing early versus delayed rehabilitation. Methods: Randomized controlled trials used in the most recent AAOS CPGs on the timing of postoperative mobilization after arthroscopic rotator cuff repairs were analyzed. Only RCTs with a reported P value ≥ .05 were included. The RFI at a threshold of P < .05 was calculated for each study. The reverse fragility quotient (RFQ) was calculated by dividing the RFI by the study sample size. Results: In 6 clinical trials with a total of 542 patients, the number of tendon re-tear events was 48. The median RFI at the P < .05 threshold was 4 (range: 3.25–4.75), and the median RFQ was .05 (range: 0.03–0.08). The median loss to follow-up was 6 patients. Of the 6 studies investigated, 3 reported a loss to follow-up greater than their respective RFI. Conclusion: The equivalence in rotator cuff repair healing rates associated with early and delayed mobilization protocols rests on fragile studies, as their statistical non-significance can be reversed by changing the outcome status of only a handful of patients. Consideration should be given to the routine reporting of RFI in clinical practice guidelines including RCTs with statistically non-significant results.
