RESUMO
BACKGROUND: Advances in total hip arthroplasty (THA) have resulted in evolving revision indications and intraoperative techniques, which can influence the exposure of trainees to complex cases. We report 3 decades of revision experience from a tertiary referral center that trains fellows, comparing the reasons for revision and the complexity of revisions over time. METHODS: We retrospectively reviewed all revision THAs performed at our institution from 1990 to 2022. Revision diagnoses, components revised, types of revision implants used, and exposure techniques were collected. A "complex" revision was defined as a case that involved an extended trochanteric osteotomy, triflange and cup-cage construct, or acetabular augment. RESULTS: A total of 3,556 THA revisions were identified (108 revisions/year). Aseptic loosening was the most common indication in 1990 to 1999 (45 per year), but decreased to 28.3/year in 2010 to 2019. From 1990 to 1999 and 2010 to 2019, fracture increased from 3.1 to 7.3 per year, infection from 2.9/year to 16.9/year, and metallosis from 0.1 to 13.2 per year. Both component revision were common from 1990 to 1994 (42.6 per year), while polyethylene exchange was most common in 2010 to 2019 (43.3 per year). A decrease was observed in "complex" cases over time: 14.8 extended trochanteric osteotomies/year in 2000 to 2004 compared to 5.4 per year in 2018 to 2022, 4.5 triflange and cup-cage constructs/year in 2004 to 2007 compared to 0.8 per year in 2018 to 2022, and 4 acetabular augments per year in 2009 to 2012 compared to 1 per year in 2018 to 2022. CONCLUSIONS: Indications for revision have changed over the decades, while the number of "complex" revisions has gradually decreased, presumably due to advances in implants and materials. If this trend extends to other training institutions, the next generation of arthroplasty surgeons will have less exposure to complex revisions during their training.

Although the efficacy of ketorolac in pain management and the short duration of use align well with current clinical practice guidelines, few studies have specifically evaluated the impact of ketorolac on bony union after fracture or surgery. The purpose of this study was to review the current basic science and clinical literature on the use of ketorolac for pain management after fracture and surgery and the subsequent risk of delayed union or nonunion. Animal studies demonstrate a dose-dependent risk of delayed union in rodents treated with high doses of ketorolac for 4 weeks or greater; however, with treatment for 7 days or low doses, there is no evidence of risk of delayed union or nonunion. Current clinical evidence has also shown a dose-dependent increased risk of pseudoarthrosis and nonunion after post-operative ketorolac administration in orthopedic spine surgery. However, other orthopedic subspecialities have not demonstrated increased risk of delayed union or nonunion with the use of peri-operative ketorolac administration. While evidence exists that long-term ketorolac use may represent risks with regard to fracture healing, insufficient evidence currently exists to recommend against short-term ketorolac use that is limited to the peri-operative period. LEVEL OF EVIDENCE V: Narrative Review.

BACKGROUND: Uncertainty remains surrounding the use of aspirin as a sole chemoprophylactic agent to reduce the risk of venous thromboembolism (deep vein thrombosis or pulmonary embolism) and bleeding after primary total hip arthroplasty. METHODS: We performed a non-inferiority analysis of a retrospective cohort of patients undergoing total hip arthroplasty from April 1, 2013 to December 31, 2018. Cases were retrieved from the Michigan Arthroplasty Registry Collaborative Quality Initiative database and performed by 355 surgeons at 61 hospitals throughout Michigan. Surgical setting ranged from small community hospitals to large academic and non-academic centers. The primary outcomes were post-operative venous thromboembolism event or death and bleeding event. RESULTS: Of the 59,747 patients included, 32,878 (55.03%) were female, and the mean age was 64.5. A total of 462 (0.77%) composite venous thromboembolism events occurred. There were 221 (0.71%) and 129 (0.80%) venous thromboembolism events in patients receiving aspirin only and anticoagulants only, respectively. Aspirin was non-inferior to anticoagulants for composite venous thromboembolism events (odds ratio 0.99, 95% confidence interval 0.79-1.26, P < .001). Bleeding events occurred in 767 (1.28%) patients, with 304 (0.97%) and 281 (1.74%) bleeding events in patients receiving aspirin only and anticoagulants only, respectively. Aspirin was non-inferior to anticoagulants for bleeding events (odds ratio 0.62, 95% confidence interval 0.52-0.74, P < .001). CONCLUSION: Aspirin is not inferior to other anticoagulants as pharmacologic venous thromboembolism prophylaxis with regards to post-operative risk of venous thromboembolism or bleeding. Sole use of aspirin for venous thromboembolism prophylaxis after total hip arthroplasty should be considered in the appropriate patient.

PURPOSE: The optimal primary treatment of localized high grade prostate cancer in younger men remains controversial. The objective of this project was to compare the impact of initial radical prostatectomy vs radiation therapy on survival outcomes in young men less than 60 years old with high grade prostate cancer. MATERIALS AND METHODS: We retrospectively analyzed the records of men younger than 60 years in the SEER (Surveillance, Epidemiology and End Results) database who underwent initial surgery or radiation therapy of high grade (Gleason score 8 or greater) localized (N0M0 TNM stage) prostate cancer from 2004 to 2012. Univariate and multivariate Cox proportional hazards regression models were used to examine prostate cancer specific and overall mortality. RESULTS: A total of 2,228 men were identified, of whom 1,459 (65.5%) underwent initial surgery and had a median followup of 43 months and 769 (34.5%) underwent initial external beam radiation therapy with or without brachytherapy and had a median followup of 44 months. On multivariate analysis initial treatment with surgery was associated with improved prostate cancer specific and overall mortality compared with initial radiation treatment (HR 0.37, 95% CI 0.19-0.74, p = 0.005 vs HR 0.41, 95% CI 0.24-0.70, p = 0.001) when controlling for age, biopsy Gleason score, T stage and prostate specific antigen. CONCLUSIONS: Our data showed significant survival differences in young men treated initially with surgery vs external beam radiation therapy of high grade prostate cancer. Future prospective randomized trials are needed to confirm the long-term outcomes of these treatment approaches.

BACKGROUND: Osteochondritis dissecans (OCD) is a condition characterized by abnormal subchondral bone with disturbance of overlying articular cartilage. The role of weightbearing alignment in the pathophysiology of OCD lesion development is not fully understood. HYPOTHESIS: Lower extremity mechanical axis would be concordant with femoral condylar OCD lesion location. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Cases were identified from a single, large academic institutional database using International Classification of Diseases, Ninth Revision and Tenth Revision and Current Procedural Terminology codes associated with OCD. Patients were included if they had a magnetic resonance imaging scan demonstrating the OCD lesion and lower extremity alignment radiographs. OCD lesion location was identified using Cahill and Berg zones. The primary outcome was the association of OCD lesion location with weightbearing mechanical axis. Secondary outcomes included the association of mechanical axis with skeletal maturity, OCD lesion stability, and treatment. For unilateral OCD lesions, mechanical axis was compared between affected and unaffected lower extremities. RESULTS: A total of 86 patients (95 knees) with an OCD lesion of the femoral condyle were identified. The population was 74% male, and the mean age was 21 years. In total, 65% of knees had closed physes, 82% of lesions were unstable, and 85% underwent a surgical procedure. Mechanical axis was located in the same zone as the OCD lesion in 48% of cases and within the same compartment in 56% of cases. Spearman correlation coefficient demonstrated a moderate positive correlation (rs = 0.59). No significant differences were found in the association of mechanical axis and OCD lesion location in subgroup analysis of medial versus lateral femoral condylar OCD lesions, skeletal maturity, stability of the lesion, or treatment group. For patients with varus alignment and medial femoral condylar OCD lesions, the mean lateral distal femoral angle was 89.9°, and medial proximal tibial angle was 85.4°; for valgus alignment and lateral femoral condylar lesions, the lateral distal femoral angle was 84.8°, and medial proximal tibial angle was 88.8°. Patients with unilateral medial femoral condylar OCD lesions were more likely to have varus alignment of the affected extremity compared with the contralateral extremity (59% vs 36%; P = .01). CONCLUSION: This study demonstrated a relationship between lower extremity mechanical weightbearing axis and femoral condylar OCD location. Patients with unilateral medial femoral condylar OCD lesions frequently had asymmetric varus alignment in the affected extremity.

Background: Patients discharged to non-home facilities (NHD) after total hip arthroplasty (THA) and total knee (TKA) arthroplasty experience higher rates of adverse events and may require more aggressive venous thromboembolism (VTE) chemoprophylaxis. Our aim was to compare the rates of VTE in NHD patients and those discharged home (HD) after THA/TKA. Our secondary aim was to determine VTE rates within HD and NHD groups when stratified by chemoprophylactic regimen. Methods: A retrospective cohort of primary THA and TKA patients were stratified into HD and NHD, then allocated into groups by chemoprophylactic regimen on discharge: aspirin alone (AA), more aggressive (MA) chemoprophylaxis, and other regimens (other). The primary outcome was VTE. Rates of VTE in HD and NHD patients, as well as AA and MA regimens, were analyzed using a generalized linear regression model. Results: Six thousand three hundred seventy-nine patients were included with 1.03% experiencing VTE. HD had lower rates of VTE compared to NHD (0.83% vs 2.17%, P < .001). AA had similar rates of VTE compared to MA (0.99% vs 1.08%, P = .82). NHD patients had a lower VTE rate with MA vs AA prophylaxis (1.47% vs 3.83%, P = .016). HD patients treated with AA vs MA had no difference in VTE rates (0.76% vs 0.96%, P = .761). Conclusions: NHD patients have higher rates of VTE than HD patients. However, NHD patients have significantly lower rates of VTE on MA chemoprophylaxis compared to those on AA. Providers should consider prescribing MA VTE chemoprophylaxis for NHD patients. Prospective, randomized studies are necessary to confirm these recommendations.
RESUMO
Background: Coronavirus disease (COVID) created unprecedented challenges, especially for high-volume elective subspecialties like total joint arthroplasty. Limited inpatient capacity and resource conservation led to new outpatient selection criteria and site of service changes. As a Michigan Arthroplasty Registry Quality Collaborative Initiative quality project, demographic changes, complications, and differential effects on inpatient vs outpatient centers pre- and post-COVID were analyzed. Methods: The registry identified all total joint arthroplasty at hospitals and ASCs/HOPDs between 07/2019-12/2019 and 07/2020-12/2020. These intervals represented pre-COVID and post-COVID elective surgery shutdowns. Case volumes, demographics, and 90-day complications were compared. Results: Comparing 2020 to 2019, hospital volumes decreased (-9% total hip arthroplasty [THA], -17% total knee arthroplasty [TKA]), and ambulatory surgery center (ASC)/hospital outpatient department (HOPD) increased (+84% THA, +125% TKA). Entering 2020, ASC/HOPD patients were older (P = .0031, P < .0001: THA, TKA), had more American Society of Anesthesiologists score 3-4 (P = .0105, P = .0021), fewer attended joint class (P < .0001, P < .0001), and more hips were women (P = .023). Hospital patients had higher preoperative pain scores (P = .0117, P < .0001; THA, TKA), less joint education attendance (P < .0001, P < .0001), younger TKAs (P = .0169), and more American Society of Anesthesiologists score 3-4 (0.0009). After propensity matching, there were no significant differences between site of service for 90-day fractures, deep vein thromboses or pulmonary embolisms, infection, or hip dislocations. Hospital THAs had higher readmissions (P = .0003) and TKAs had higher 30-day emergency department visits (P = .005). ASC/HOPD patients were prescribed higher oral morphine equivalents (P < .0001, P < .0001; THA, TKA). Conclusions: COVID's elective surgery shutdown caused a dramatic site of service shift. Traditional preoperative education was negatively impacted, and older and sicker patients became outpatients. But short-term complications were not increased in ASCs/HOPDs. These site of service and associated patient demographic changes may be safely sustained.
RESUMO
CASE: A 60-year-old woman presented with knee instability and pain that started approximately 13 years after a posterior stabilized total knee arthroplasty. Physical examination revealed significant posterior laxity. Bedside ultrasound (US) documented a free-floating, hyperechoic linear artifact within the posterior knee joint capsule. Revision with liner of increased thickness alleviated presenting symptoms. CONCLUSION: Tibial postfractures often present with instability and pain. Diagnosis of a tibial postfracture can be based on clinical examination; other diagnostics commonly used include arthroscopy or computed tomography/magnetic resonance imaging. US by a qualified sonographer is a potential diagnostic route that should be explored more rigorously.

Background: In 2013, the Centers for Disease Control and Prevention reduced the periprosthetic joint infection (PJI) surveillance period from 1 year to 90 days for total hip (THA) and knee arthroplasty (TKA). Our aim was to determine how the reduced surveillance window impacts capture of PJIs. Material and methods: Primary and revision THA and TKA cases were retrospectively identified in a statewide registry from October 1, 2015, to September 30, 2018. Infections were defined using the Periprosthetic Joint/Wound Infection measure (Centers for Medicare and Medicaid Services). We compared the cumulative incidence of infected primary and revision THA (pTHA/rTHA) and TKA (pTKA/rTKA) at 0-90 days and 91-365 days postoperatively. Results: A total of 136,491 patients were included, 59.59% female, mean age 65.8 years, and mean body mass index 32.3 kg/m2. The overall rate of PJI diagnosed by 1 year was 1.33%. The percent of infections diagnosed between 0-90 days and 91-365 days were pTHA 76.78% and 23.22%, rTHA 74.12% and 25.88%, pTKA 57.67% and 42.33%, and rTKA 53.78% and 46.22%, respectively. More infections were diagnosed after 90 days in pTKA than in pTHA and in rTKA than in rTHA (P < .0001). There was a higher risk of infection throughout the year when comparing rTKA to rTHA (P = .0374) but not when comparing pTKA to pTHA (P = .0518). Conclusion: A substantial portion of infections are missed by the 90-day surveillance period. More infections are missed after TKA than after THA. Extension of the surveillance period would allow for identification of opportunities for quality improvement.
RESUMO
Background: Using alternating orthogonal suture throws with the looped whipstitch technique may allow enhanced suture fixation. Hypothesis: It was hypothesized that this novel multiplanar, perpendicular looped whipstitch (MP) technique would have improved biomechanical properties compared with the standard looped whipstitch (WS) and Krackow stitch (KS). Study Design: Controlled laboratory study. Methods: A total of 30 cadaveric tibialis anterior tendons were randomly assigned into 3 groups of 10. Tendons were secured to a custom clamp, and the other end was sutured using 1 of 3 techniques: the KS, WS, or novel MP. The MP was performed with alternating orthogonal throws starting right to left, then front to back, left to right, and back to front. Each technique used 4 passes of No. 2 FiberWire spaced 5 mm apart and ending 10 mm from the tendon end. Tendons were preloaded to 5 N, pretensioned to 50 N at 100 mm/min for 3 cycles, returned to 5 N for 1 minute, cycled from 5 to 100 N at 200 mm/min for 100 cycles, and then loaded to failure at 20 mm/min. Elongation was recorded after pretensioning and cycling and was measured both across the suture-tendon interface and from the base of the suture-tendon interface to markings on the suture limbs (construct elongation). One-way analyses of variance were performed, with Bonferroni post hoc analysis when appropriate. Results: There were no differences in cross-sectional area or stiffness among the 3 techniques. The ultimate load for WS (183.33 ± 57.44 N) was less compared with both MP (270.76 ± 39.36 N) and KS (298.90 ± 25.94 N) (P ≤ .001 for both). There was less construct elongation for KS compared with WS and MP for total displacement, measured from pretensioning to the end of cycling (P < .001). All 3 techniques saw a decrease in length (shortening) at the suture-tendon interface during testing. There was more shortening at the suture-tendon interface for WS compared with KS (P = .006). Conclusion: The KS appears superior, as it maximized strength while minimizing construct elongation or graft shortening. The ultimate load of the MP technique was greater than that of the standard technique but not significantly different from that of the KS technique. Clinical Relevance: The KS is preferred. If using a WS, multiplanar, perpendicular passes should be considered.
RESUMO
Background: Obesity is associated with increased complications after total joint arthroplasty (TJA), leading some surgeons to recommend nutrition counseling and weight loss. We aim to evaluate the effect of preoperative nutritionist referral on weight loss and likelihood of surgery in obese patients seeking primary TJA. Methods: A retrospective cohort of patients seeking primary TJA who were referred to a licensed nutritionist for weight loss was matched by age, sex, and body mass index (BMI) to an unreferred control group. BMI change was compared between groups up to 1 year of follow-up. Differences were determined using 2-tailed t-tests and chi-squared tests with a significance cutoff of P < .05. Results: A total of 274 referred patients and 174 controls were included in our analysis. Patients who were referred to a nutritionist achieved significantly greater average BMI change (-1.5 kg/m2) than controls (-0.8 kg/m2) by 6 months after first contact (P = .01) although significance was lost at 1 year after first contact (P = .21). Thirty-eight percent of referred patients went on to TJA compared with 28% of controls (P < .01). Conclusions: Referral to a licensed nutritionist modestly improves early weight loss and is associated with a higher rate of surgery in obese patients seeking primary TJA.
RESUMO
Venous thromboembolism is a well-established complication of total hip and knee arthroplasty and hip fracture surgery. Clinical practice guidelines have been proposed to help clinicians provide prophylaxis against this risk. However, most guidelines reference data that are becoming outdated because of new advances in perioperative protocols. Recent data would suggest that aspirin may be appropriate for most patients after total hip and knee replacement and a more potent chemoprophylaxis for higher risk patients. Low-molecular-weight heparin remains the recommended choice after hip fracture surgery, although there is a paucity of recent literature in this patient population. There are randomized trials currently underway in the arthroplasty population that may guide clinicians in the appropriate choice of chemoprophylaxis. These studies should inform updates to the current clinical practice guidelines.
RESUMO
BACKGROUND: The effect of non-steroidal anti-inflammatory medications (NSAIDs) on fracture healing is a topic of debate. The purpose of this study was to systematically review the effect of NSAID medications on spinal fracture healing rates. METHODS: We searched the Cochrane Library, PubMed, Medline Ovid, and SCOPUS databases from inception until April 2021, and additionally searched the NIH Clinical Trials Database. Eligible studies included those which reported on spinal fracture healing rates in patients taking NSAIDs. Two reviewers independently assessed all potential studies for eligibility and extracted data. Risk of bias was assessed with validated tools by two reviewers. The primary outcome of interest was healing rates of spinal fractures in patients taking NSAIDs. Secondary outcomes of interest included healing rates stratified by NSAID selectivity. RESULTS: A total of 1,715 studies were initially screened. After inclusion criteria were applied, three studies (214 patients) were included which discussed spinal fracture healing rates in patients taking NSAIDs. These studies showed acceptable reliability for inclusion. The 3 studies reported heterogeneous results, with one study reporting a 96% healing rate, and another study reporting over 90% non-union rate. The types of fracture, NSAID type, and dosage/duration of NSAID use varied widely amongst studies. DISCUSSION: This systematic review identified a significant paucity in the literature on the effect of NSAID medications on spinal fracture healing rates. Given the limited number of studies, as well as the heterogeneous results and methods from these studies, no consensus statement can be made on the safety profile of NSAIDs in the context of spinal fractures. Further studies are needed to better address this question.
RESUMO
Sacroiliac joint (SIJ) pathology is a common cause of significant pain and disability, and operative treatment consisting of SIJ fusion can be performed in cases where non-operative measures fail to provide sustained relief. Through the years, SIJ fusion has evolved from an open invasive procedure, to more recently, being performed through minimally invasive techniques. Intraoperative navigation systems and robotic guidance are becoming popularized for SIJ fusion, as well as other routine and complex spinal cases. The utility of navigation and robotics is the enhanced ability of the surgeon to place instrumentation more accurately, with less dissection, blood less, and overall operative time. We present a technique guide for robotic instrumented SIJ fusion with intraoperative navigation that we have put into practice at our institution and found to be very beneficial to patients for the above reasons. We describe the setup and utilization of these technologies intraoperatively, and provide specific case examples to highlight our technique. The described methods have been found to be effective and reproducible, allowing for minimally invasive SIJ screw placement with high accuracy and safety. We emphasize that utilizing intraoperative navigation and robotics is not meant to substitute for surgeon knowledge of case steps or anatomy, but rather to enhance safety and efficacy. To our knowledge, robotic SIJ fusion has not been previously described in the literature.
RESUMO
CASE: Evidence-based surgical strategies to reconstruct the collateral ligament complex of the first metatarsophalangeal (MTP) joint are not available. We report a case of first MTP lateral collateral ligament insufficiency in a young, female gymnast with varus laxity and subsequent satisfactory mid-term and long-term outcomes. CONCLUSION: This case report describes an efficient suture anchor technique for restoring stability of the first MTP joint because of chronic varus laxity with acceptable results both clinically and with patient-reported outcome scores at mid-term and long-term follow-ups. We suggest that our strategy is a viable option for addressing chronic varus laxity of the first MTP joint. LEVEL OF EVIDENCE: Level IV, case report.

RESUMO
OBJECTIVES: This study aims to systematically assess the existing literature and to derive a pooled estimate of the prevalence of depression and posttraumatic stress disorder (PTSD) in adult patients after acute orthopaedic trauma. DATA SOURCES: A comprehensive search of databases, including MEDLINE, Embase, PsycINFO, and Cochrane Central Register of Controlled Trials databases was conducted through June 2015. STUDY SELECTION: We included studies that assessed the prevalence of depression or PTSD in patients who experienced acute orthopaedic trauma to the appendicular skeleton or pelvis. Studies with a sample size of ≤10 were excluded. DATA EXTRACTION: Two authors independently extracted data from the selected studies and the data collected were compared with verify agreement. DATA SYNTHESIS: Twenty-seven studies and 7109 subjects were included in the analysis. Using a random-effects model, the weighted pooled prevalence of depression was 32.6% (95% CI, 25.0%-41.2%) and the weighted pooled prevalence of PTSD was 26.6% (95% CI, 19.0%-35.9%). Six studies evaluated the prevalence of both depression and PTSD in patients with acute orthopaedic injuries. The weighted pooled prevalence of both depression and PTSD for those patients was 16.8% (95% CI, 9.0%-29.4%). CONCLUSIONS: Nearly one-third of patients suffer from depression and more than one-quarter of patients suffer from PTSD after an acute orthopaedic injury suggesting that strategies to address both the mental and physical rehabilitation after an orthopaedic injury should be considered to optimize patient recovery. LEVEL OF EVIDENCE: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

The benefits of high-pressure pulsatile lavage for open fracture irrigation have been controversial based on conflicting experimental animal research. Recently published data definitively demonstrated that irrigation pressure does not affect the incidence of reoperation for the treatment of open fractures. However, proponents of pulsatile lavage argue a faster irrigation time is an important benefit of the high-pressure treatment. The purpose of this study was to determine the difference in irrigation time between gravity and high-pressure lavage. The experimental setup was designed to mimic clinical practice and compared mean irrigation flow times for high-pressure pulsatile lavage and gravity flow with 2 commonly used tube diameters. Each irrigation setup was tested 5 times at 3 different irrigation bag heights. Analysis of variance and Student's t tests were used to compare the mean flow times of 3 irrigation methods at each height and among the 3 heights for each irrigation method. The mean irrigation flow time in the various experimental models ranged from 161 to 243 seconds. Gravity irrigation with wide tubing was significantly faster than pulsatile lavage or gravity with narrow tubing (P<.001). Increasing irrigation bag height had only a marginal effect on the overall flow times (<9% difference). The difference in mean flow time among the testing techniques was slightly longer than 1 minute, which is unlikely to have a material impact on procedural costs, operating times, and subsequent gains in patient safety.
