Improved Patient-reported Outcomes in Patients Aged 16 and Younger at Two Years After Anterior Cruciate Ligament Reconstruction Despite Relatively High Rates of Reinjury and Repeat Surgery.

BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) in adolescent patients, particularly those aged 16 and under, are increasingly common procedure that lacks robust clinical and patient-reported outcome (PRO) data. The purpose of this study was to report 2-year PROs of patients receiving ACLR aged 16 or younger using the single assessment numerical evaluation (SANE) and knee injury and osteoarthritis outcome score (KOOS). Secondary aims included characterizing treatment characteristics, return to sport (RTS), and clinical outcomes. METHODS: The institutional PRO database was queried for patients receiving ACLR from 2009 to 2020. Patients aged older than 16, revision procedures, concomitant ligament repairs/reconstructions, and patients without full outcome data at 2 years were excluded. Outcomes over 2 years after ACLR included SANE, KOOS, reinjuries, reoperations, and time to RTS. RESULTS: A total of 98 patients were included with an average age of 15.0 years. Most patients were females (77.6%). Bone-tendon-bone autograft (69.4%) was the most used. Average RTS was 8.7 months (range: 4.8 to 24.0 mo), with 90% of patients eventually returning to sport. A total of 23 patients (23.5%) experienced a reinjury and 24.5% (n = 24) underwent reoperation. Timing to RTS was not associated with reinjury, but patients who returned between 9.5 and 13.7 months did not sustain reinjuries. Mean KOOS and SANE scores at 2 years were 87.1 and 89.1, respectively, with an average improvement of +18.4 and +22.9, respectively. Change in KOOS was negatively impacted by reinjury to the anterior cruciate ligament graft and reoperation (anterior cruciate ligament failure: +10.0 vs 19.3, P = 0.081, respectively; reoperation: +13.2 vs +20.1, P = 0.051, respectively), though these did not reach statistical significance. CONCLUSION: Patients experienced improved SANE and KOOS scores after ACLR. Rates of reinjury and reoperation were relatively high and negatively impacted PRO scores but were not associated with the timing of RTS. Adolescent patients should be counseled regarding the risk of subsequent ipsilateral and contralateral knee injury after ACLR. LEVEL OF EVIDENCE: Level IV-case series.

Measurement of value in rotator cuff repair: patient-level value analysis for the 1-year episode of care.

BACKGROUND: Rotator cuff repair (RCR) is one of the most common elective orthopedic procedures, with predictable indications, techniques, and outcomes. As a result, this surgical procedure is an ideal choice for studying value. The purpose of this study was to perform patient-level value analysis (PLVA) within the setting of RCR over the 1-year episode of care. METHODS: Included patients (N = 396) underwent RCR between 2009 and 2016 at a single outpatient orthopedic surgery center. The episode of care was defined as 1-year following surgery. The Western Ontario Rotator Cuff index was collected at both the initial preoperative baseline assessment and the 1-year postoperative mark. The total cost of care was determined using time-driven activity-based costing (TDABC). Both PLVA and provider-level value analysis were performed. RESULTS: The average TDABC cost of care was derived at $5413.78 ± $727.41 (95% confidence interval, $5341.92-$5485.64). At the patient level, arthroscopic isolated supraspinatus tears yielded the highest value coefficient (0.82; analysis-of-variance F test, P = .01). There was a poor correlation between the change in the 1-year Western Ontario Rotator Cuff score and the TDABC cost of care (r2 = 0.03). Provider-level value analysis demonstrated significant variation between the 8 providers evaluated (P < .01). CONCLUSION: RCR is one of the most common orthopedic procedures, yet the correlations between cost of care and patient outcomes are unknown. PLVA quantifies the ratio of functional improvement to the TDABC-estimated cost of care at the patient level. This is the first study to apply PLVA over the first-year episode of care. With health care transitioning toward value-based delivery, PLVA offers a quantitative tool to measure the value of individual patient care delivery over the entire episode of care.

Corridor-diameter-dependent angular tolerance for safe transiliosacral screw placement: an anatomic study of 433 pelves.

BACKGROUND: The purpose of this study was to determine the angular tolerance of the S1 and S2 segments to accommodate a transiliosacral screw across both sacroiliac joints. HYPOTHESIS: We hypothesized that the angular tolerance for transiliosacral screw placement would be more constrained than the angular tolerance for iliosacral fixation in pelves where a safe osseous corridor was measured. MATERIALS AND METHODS: The cortical boundaries of the S1 and S2 sacral segments in 433 pelvic CTs were digitally mapped. A straight-line path was placed within each osseous corridor and extended across both SI joints past the outer iliac cortices. The diameter of the path was increased until it breached the cortex, geometrically determining maximum diameter (Dmax). Angular tolerance for screw placement was calculated with trigonometric analysis of the Dmax value of the corridor, and the average distance from the termination of the osseous corridor to the site of percutaneous insertion. Gender, age, and BMI were evaluated as independent predictors using binomial logistic regression. RESULTS: The transiliosacral angular tolerance for the S1 and S2 osseous corridors was 1.53 ± 0.57 degrees and 1.02 ± 0.33 degrees, respectively. 68.9% of S1 corridors and 81.1% of S2 corridors had a safe zone (corridor diameter ≥ 10 mm) for transiliosacral placement, 48.3% of the pelves had a safe zone for both corridors, while 5.1% had no safe zones. Females had a less frequent Dmax ≥ 10 mm at S1, 52% vs 67% (p = 0.001), and at S2, 64% vs 86% (p < 0.001). DISCUSSION: In conclusion, the angular tolerance of 1.53 and 1.03 degrees for the S1 and S2 segments, respectively, creating a narrow interval for safe passage of the trans-iliac and trans-sacral, with approximately 31.1% of patients not having a viable corridor for screw passage. A correlation exist between S1 and S2 corridors with Dmax ≥ 10 mm and the resulting increase in angular tolerance for safe passage of a transilioscral screw.

Preoperative Function Affects Ability to Achieve One-Year Minimum Clinically Important Difference for Patients Undergoing Total Knee Arthroplasty.

Background: Minimum clinically important difference (MCID) values are commonly used to measure treatment success for total knee arthroplasty (TKA). MCID values vary according to calculation methodology, and prior studies have shown that patient factors are associated with failure to achieve MCID thresholds. The purpose of this study was to determine if anchor-based 1-year Knee Injury and Osteoarthritis Outcome Score Joint Replacement (KOOS-JR) MCID values varied among patients undergoing TKA based on patient-specific factors. Methods: This was a retrospective review of patients undergoing TKA from 2017-2018. Patients without baseline or 1-year KOOS-JR or Patient-Reported Outcome Measurement Information System Global Health data or that underwent procedures other than primary TKA were excluded. MCIDs were calculated and compared between patient groups according to preoperative characteristics. Results: Among the included 976 patients, 1-year KOOS-JR MCIDs were 26.6 for men, 28.2 for women, 30.7 for patients with a diagnosis of anxiety and/or depression, and 26.7 for patients without a diagnosis. One-year MCID values did not differ significantly according to gender (P = .379) or mental health diagnosis (P = .066), nor did they correlate with body mass index (ß = -0.034, P = .822). Preoperative KOOS-JR decile demonstrated an inverse relationship with 1-year MCID values and attainment of MCID. Conclusions: The proportion of patients attaining KOOS-JR MCID values demonstrated an inverse relationship with preoperative baseline function. Future investigation may identify patient factors that allow surgeons to better capture patient satisfaction with their procedure despite failure to attain a 1-year MCID.

Use of Social Media in Orthopaedic Surgery Training and Practice: A Systematic Review.

Background: Social media use has grown across healthcare delivery and practice, with dramatic changes occurring in response to the coronavirus (COVID-19) pandemic. The purpose of this study was to conduct a comprehensive systematic review to determine the current landscape of social media use by (1) orthopaedic surgery residencies/fellowship training programs and (2) individual orthopaedic surgeons and the change in use over time. Methods: We searched 3 electronic databases (PubMed, MEDLINE, and Embase) from their inception to April 2022 for all studies that analyzed the use of social media in orthopaedic surgery. Two reviewers independently determined study eligibility, rated study quality, and extracted data. Methodology was in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results: Twenty-eight studies were included, of which 11 analyzed social media use by orthopaedic surgery residency and fellowship training programs and 17 examined its use by individual orthopaedic surgeons. Among residency and fellowship programs, Instagram was identified as the most common platform used, with 42% to 88% of programs reporting program-specific Instagram accounts, followed by Twitter/X (20%-52%) and Facebook (10%-38%). Social media was most commonly used by programs for recruitment and information dissemination to prospective residency applicants (82% and 73% of included studies, respectively). After the start of the COVID-19 pandemic, there was a 620% and 177% increase in the number of training programs with Instagram and Twitter/X accounts, respectively. Individual use of social media ranged from 1.7% to 76% (Twitter/X), 10% to 73% (Facebook), 0% to 61% (Instagram), 22% to 61% (LinkedIn), and 6.5% to 56% (YouTube). Conclusions: Instagram, Twitter/X, and Facebook are the premier platforms that patients, residency applicants, and institutions frequent. With the continued growth of social media use anticipated, it will be critical for institutions and individuals to create and abide by guidelines outlining respectful and professional integration of social media into practice.

Cerebral desaturation events during shoulder arthroscopy in the beach chair position: patient risk factors and neurocognitive effects.

BACKGROUND: Patients undergoing shoulder surgery in the beach chair position may be at increased risk for serious neurocognitive complications due to cerebral ischemia. We sought to define the incidence, patient risk factors, and clinical sequelae of intraoperative cerebral desaturation events. METHODS: Regional cerebral tissue oxygen saturation (rSO2) was monitored intra-operatively using near-infrared spectroscopy (NIRS) on 50 consecutive patients. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was administered to each patient pre- and postoperatively. Intra-operative decreases in rSO2 of 20% or greater were defined as cerebral desaturation events (CDE). The association between intraoperative CDE and postoperative cognitive decline was assessed. RESULTS: The incidence of intraoperative CDE in our series was 18% (9/50). Increased body mass index (BMI) was found to have a statistically significant association with intraoperative CDE (mean BMI 37.32 vs 28.59, P < .0001). There was no statistical significance in pre- vs postoperative RBANS either in composite scores or any of the sub-indices in either group. CONCLUSION: The degree and duration of cerebral ischemia required to produce neurocognitive dysfunction in this patient population remains undefined; however, cerebral oximetry with NIRS allows prompt identification and treatment of decreased cerebral perfusion decreasing the risk of this event. Increased BMI was found to be a statistically significant patient risk factor for the development of intra-operative CDE. The transient intra-operative CDEs were not associated with postoperative cognitive dysfunction in our patient series. We believe protocols aimed at detecting and reversing CDE minimize the risk of neurocognitive dysfunction and improve patient safety.

Are Canadian orthopaedic surgeons and American orthopaedic surgeons on par? A Canadian practice survey of orthopaedic traumatologists.

Objectives: The purpose of this study was to obtain information on Canadian orthopaedic trauma surgeon practices and salary demographics. It was hypothesized that most of the practicing surgeons recognize specific practice aspects (compensation, call schedule, operating room availability, and provided support staff) as key factors in employment opportunity evaluation. Design: Cross-sectional survey study. Setting: Orthopaedic Trauma Association (OTA) practice surveys. Participants: All active Canadian members of the OTA were eligible to participate. Main Outcome Measurement: A 50-question survey was sent through email to OTA members assessing physician, practice, and compensation metrics of Canadian orthopaedic traumatologists. Results: Fifty-two of 113 Canadian OTA members participated giving a response rate of 46%. All surgeons worked in an academic practice, either for a university (83%) or community hospital (17%). Only 2% of surgeons have changed jobs in the last 5 years, and over 73% of surgeons maintain the same place of employment during their careers. Most had an available dedicated orthopaedic trauma operating room (73%). The majority indicated having residents (71%) and fellows (63%) as support staff. Many reported completing 300-500 cases per year (42%), which decreased during COVID-19 for 50% of surgeons. The most common reported compensation was between $400,000 and $600,000 US dollars (25%) with many working 4-6 call shifts a month (48%) and 51-70 hours a week (48%). Conclusion: This study demonstrated the varying practice and physician economic variables currently in Canada. The identification and continued surveillance of these employment variables will allow for transparency in job market evaluation by applicants. Level of Evidence: Level V.

Autograft patellar bone-tendon-bone use does not increase operative time in anterior cruciate ligament reconstruction.

Background: Anterior cruciate ligament reconstruction (ACLR) is a common procedure that has been shown to have relatively good outcomes amongst various graft types. Operative time in ACLR has been found to influence outcomes and cost. The purpose of this study was to evaluate the association of operative time in primary arthroscopically performed anterior cruciate ligament reconstruction (ACLR) and graft type while controlling for confounders that influence time. Methods: All patients who received ACLR between 2018 and 2022 were included in this retrospective cohort study. Exclusion criteria consisted of age (≤16 years), revisions, concomitant ligament reconstruction or tendon repairs, or other simultaneously performed procedures that could potentially add substantial variation in operative time. The primary outcome was operative time. Graft types included allograft, bone-tendon-bone (BTB) autograft, hamstring tendon (HS) autograft and quadriceps tendon (QT) autograft. Results: A total of 1813 primary ACLRs were included. The average operative time was 98.9 ± 33.0 min. Graft utilization varies considerably among surgeons. The most used graft type was BTB autograft (42.6%) followed by HS autograft (32.3%) and allograft (21.4%). Only 68 cases (3.8%) used a QT autograft. Seven of the 15 included surgeons primarily used BTB autograft. One surgeon predominately used QT autograft. No difference in operative time was observed among the autograft types (p = 0.342). Allograft ACLR was significantly faster by 27-33 min compared to using BTB autograft, HS autograft, or QT autograft (p < 0.001). Conclusion: Operative time did not vary by type of autograft selected. Allograft ACLR was performed approximately 30 min faster than autograft ACLR. Further studies examining the effect on patient outcomes of reduced operative time and minimizing graft harvest morbidity in ACLR is important to more accurately determine the cost-effectiveness of allograft ACLR.

Medial femoral circumflex artery pseudoaneurysm following intramedullary nailing for intertrochanteric fracture.

CASE: We present the case of a 92-year-old woman who developed a medial femoral circumflex artery (MFCA) pseudoaneurysm intraoperatively while obtaining reduction during intramedullary nailing (IMN) for intertrochanteric fracture. CONCLUSIONS: Pseudoaneurysms are rare vascular complications in hip fracture surgery. Early recognition of signs and symptoms of this phenomenon are essential for diagnosis and treatment. Close post-operative monitoring and serial hemoglobin should be considered for unexplained intra-operative bleeding. A low threshold for angiography should be entertained if active bleeding and clinical decompensation occur during instrumented percutaneous pertrochanteric fracture reduction. This patient underwent conventional angiography with successful coil embolization and exclusion of the MFCA pseudoaneurysm.

Evolving perceptions regarding receiving orthopaedic care during the Coronavirus 2019 (COVID-19) pandemic: a follow-up survey.

As the Coronavirus 2019 (COVID-19) pandemic evolves, it is critical to understand how patients' feelings and perceptions have changed. The aim of this study was to understand current feelings and concerns about seeking and receiving orthopaedic care 9 mo into the global pandemic. METHODS: Utilizing a survey developed to evaluate the attitudes and beliefs from healthcare respondents about receiving care during the COVID-19 pandemic, an updated and revised version, evaluating changes in perception of respondents 9 mo into the pandemic, was distributed to a group of panelists by email. RESULTS: Out of 1200 individuals, 197 (16%) completed the survey. A majority of respondents reported high level of comfort in the immediate or near-term receiving care in an orthopaedic clinic, urgent care clinic specifically for orthopaedics, or in an emergency room. Six percent of respondents reported a delay in seeking orthopaedic care despite COVID-19 concerns that occurred between studies. Respondents reported their primary reason for delaying care was because of concerns for risk of COVID-19 exposure from other patients (83%). More than 75% of respondents stated they are "extremely" or "very" likely to get the COVID-19 vaccine when it becomes available to the public. Respondents had a generally negative outlook on pandemic efforts locally to globally. CONCLUSIONS: Despite dismal overall perceptions regarding the outlook of the pandemic; consumers are becoming increasingly comfortable obtaining orthopaedic care. The ability of healthcare providers and practices to adherence to safety protocols will remain essential to maintaining consumer trust and confidence. LEVEL OF EVIDENCE: Level IV.

Standardizing Screw Head Orthopaedic Trauma Implants. Is There an Interest? An OTA Member Survey.

OBJECTIVE: To determine the level of interest in standardization of design for fracture fixation implants within the orthopaedic trauma community. METHODS: A survey regarding implant removal concerns and implant design preferences was electronically distributed to members of Orthopaedic Trauma Association (OTA). RESULTS: Three hundred thirty respondents participated in the survey (response rate of 19%) Only 2.4% of respondents indicated a consistent ability to identify the implant vendor and/or manufacturer of retained implants in the preoperative planning phase of care; >75% of respondents reported investing a minimum of an additional 30 minutes to their operative times to remove screw(s) to successfully extract a plate. More than 80% of respondents reported multiple occurrences requiring modification of their surgical plans because of implants that could not be removed, preventing the completion of the planned procedure. The majority of respondents expressed interest in the adoption of standardized locking head screws for mini, small, and large screw sizes sets (63.5%); 84.8% of respondents desire standardization of screw head and driver sizes across the industry. Also, 83.6% of respondents expressed interest in the adoption of a standardized locking screw head for each cannulated screw, regardless of manufacturer. CONCLUSIONS: Members of the orthopaedic community, as represented in the membership of the OTA, are interested in the adoption of universal standards in implant design. Establishing standard screw heads and drivers will optimize the delivery of operative care.

Creative bracing: A descriptive overview of an alternative technique for non-operative fracture management of frail older adults.

As the world population ages, a higher proportion of older and frailer patients will sustain fragility fractures. Considering their depleted physiologic reserve and potentially different goals of care at their stage in life, these patients; especially those enrolled in hospice care, with profound dementia, or at end-of-life care; may not benefit from traditional surgical methods of fracture care. Non-operative treatment using standard immobilization or casting techniques in older and frailer patients can still render them susceptible to complications and adverse events. Here we describe our alternative non-operative treatment method of creative bracing to address the needs of this specific population. Creative bracing can be done with simple supplies available in almost all healthcare settings. Through patient-specific pre-treatment assessment, a creative brace tailored to the patient's risk factors and goals of care can be designed to provide sufficient fracture immobilization and comfort. Creative bracing is a low-cost, low-technical demand modality for non-operative treatment of some fragility fractures. Its benefit can be appreciated to greatest effect in the frailest patients for whom standard, surgical treatment does not represent best care.

Low-energy suspiciously open proximal humerus fracture management in older adult patient: A case report.

Although fractures of the proximal humerus are common among older adults, open fractures following low-energy trauma are exceptionally rare. Prior studies have alluded to the existence of this injury, but there are no detailed reports on its presentation, management, or long-term follow-up. We present the case of a 78-year-old man that sustained a suspiciously open proximal humerus fracture of the dominant hand following a fall down a few stairs. Management consisted of early intravenous antibiotics followed by open reduction and internal fixation with irrigation and debridement. Intraoperative soft tissue assessment revealed a wound extending from bone to skin. The patient suffered no complications, regained full function of his arm, and is pain free. Considering the rarity of this injury and its potential for highly morbid complications, this case serves as a reminder that we should continue to have a low suspicion threshold for open fracture when punctures or lesions are present around proximal humerus fractures, even for low-energy injuries. Prompt and thorough examination, initiation of antibiotics, and surgical intervention are keys to providing best care for this uncommon injury.

Cost Variation in Temporizing External Fixation of Tibial Plateau and Pilon Fractures: Is There Room to Improve?

INTRODUCTION: External fixator costs have been shown to be highly variable. Current information on external fixator costs and cost drivers is limited. The aim of this study was to examine the cost variation as well as the patient-, injury-, and surgeon-related cost drivers associated with temporizing external fixation constructs in tibial plateau and pilon fracture management. MATERIALS AND METHODS: A retrospective review was conducted to identify isolated tibial plateau and pilon fractures treated with temporizing external fixation from 2006-2018 at a level 1 trauma center. Inclusion criteria were based on fractures managed with primary external fixation, skeletal maturity, and isolated ipsilateral fracture fixation. Fracture patterns were identified radiographically using Schatzker, Weber, and OTA classification systems. Implant costs were determined using direct purchase price from the institution. The primary outcome was the external fixator total construct cost. Clinical covariates and secondary outcomes, namely unplanned reoperations, were extracted. Factors associated with cost (i.e. cost drivers) were identified via multivariable regression analysis. RESULTS: A total of 319 patients were included in this study (121 tibial plateau and 198 pilon fractures). Mean plateau construct cost was $5,372.12 and mean pilon construct cost was $3,938.97. Implant cost correlated poorly with demographic (r2=0.01 & r2=0.01), injury-independent (r2<0.01 & r2=0.03), and fracture pattern classifications (r2=0.03 & r2=0.02). Traumatologists produced significantly cheaper implants for pilon fractures (p=0.05) but not for plateau fractures (p=0.85). There was no difference in construct cost or components between patients that underwent unplanned reoperation and those that did not for both tibial plateau (p>0.19) and pilon (p>0.06). Clamps contributed to 69.9% and 77.3% of construct costs for tibial plateau and pilon, respectively. The most cost-efficient fixation constructs for tibial plateau and pilon fractures were the following respectively: of 5 clamps, 2 bars, and 4 pins; and of 4 clamps, 2 bars, and 3 pins. CONCLUSIONS: There is large cost variation in temporizing external fixation management. Cost drivers included surgeon bias and implant preference as well as use of external fixator clamps. Introducing construct standardization will contain healthcare spending without sacrificing patient outcomes. LEVEL OF EVIDENCE: Level III. Retrospective Cohort.

Cost Reduction for Knee-Spanning External Fixation in the Staged Treatment of Tibial Plateau Fractures: A Practical Intervention.

OBJECTIVE: To determine whether an educational intervention affects surgeon implant decision making measured by total implant costs for temporizing a knee-spanning external fixation construct. DESIGN: A total of 24 cases were prospectively collected after an educational intervention and matched to 24 cases before intervention using Schatzker classification and by surgeon. SETTING: A single Level 1 trauma center. PATIENTS/PARTICIPANTS: Forty-eight patients with Schatzker II-VI tibial plateau fractures. INTERVENTION: Education session to create transparency with component pricing and to provide 3 clinical cases of Orthopaedic Trauma Association/AO 41-C3 (Schatzker VI) with accompanying images and fixator construct costs. Total implant costs displayed in the session ranged from $2354 to $11,696. OUTCOME MEASUREMENT: External fixator construct cost. RESULTS: The mean cost of constructs in the postintervention group was $4550.20 [95% confidence interval (CI) $3945.60-$5154.00], which was significantly different compared with the preintervention group cost of $6046.75 (95% CI = $5309.54-$6783.97, P = 0.003). After 1 year, the total implant costs of external fixation constructs were reduced by an average of almost $1500 per patient. CONCLUSION: An educational intervention created a reduction in the average total implant construction costs for temporary knee-spanning external fixation in the treatment of tibial plateau fractures. Surgical implant selection and cost variance remain an ideal area to improve value for patients and hospitals. Empowering surgeons with knowledge regarding implant prices is a critical part of working toward the cost reductions of external fixation constructs.

Cost and Cost Driver Analysis of Anterior Cruciate Ligament Reconstruction Using Time-Driven Activity-Based Costing: Bone-Tendon-Bone Autograft Versus Hamstring Autograft.

As health care transitions toward value-based care, orthopaedics has started to implement time-driven activity-based costing (TDABC) to understand costs and cost drivers. TDABC has not previously been used to study cost drivers in anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to use TDABC to (1) calculate bone-tendon-bone (BTB) and hamstring ACLR total costs of care and (2) evaluate the impact of graft choice and other factors on ACLR costs. Methods: Data were collected from electronic medical records for primary ACLR from the institutional patient-reported outcome registry between 2009 and 2016 in 1 ambulatory surgery center. Patients receiving allograft, revision ACLR, or concomitant meniscal repair or ligament reconstruction were excluded. The total cost of care was determined using TDABC. Multivariate regression analysis was conducted between ACLR cost and group characteristics. Results: A total of 328 patients were included; 211 (64.3%) received BTB autograft and 117 (35.7%) received hamstring autograft. The mean cost was $2,865.01 ± $263.45 (95% confidence interval: $2,829.26, $2,900.77) for BTB ACLR versus $3,377.44 ± $320.12 ($3,318.82, $3,436.05) for hamstring ACLR (p < 0.001). Operative time was 103.1 ± 25.1 (99.7, 106.5) minutes for BTB ACLR versus 113.1 ± 27.9 (108.0, 118.2) minutes for hamstring ACLR (p = 0.001). The total implant cost was $270.32 ± $97.08 ($257.15, $283.50) for BTB ACLR versus $587.36 ± $108.78 ($567.44, $607.28) for hamstring ACLR (p < 0.001). Hamstring graft (p = 0.006) and suspensory fixation on the femoral side (p = 0.011) were associated with increased costs. Conclusions: The mean cost of care and operative time for BTB autograft ACLR are less than those for hamstring autograft ACLR. Operative time, implant choice, and graft choice were identified as modifiable cost drivers that can empower surgeons to manage primary ACLR costs while maximizing the value of the procedure.

External Fixation Characteristics Drive Cost of Care for High-Energy Tibial Plateau Fractures.

OBJECTIVE: To determine the total cost for a 30-day episode of care for high-energy tibial plateau fractures and the aspects of care associated with total cost. DESIGN: Time-driven activity-based costing analysis. SETTING: One Level 1 adult trauma center. PATIENTS: One hundred twenty-one patients with isolated, bicondylar tibial plateau fractures undergoing staged treatment were reviewed. PRIMARY OUTCOME: Total cost. RESULTS: A total of 85 patients were included and most sustained Schatzker VI fractures (n = 66, 77%). All patients were treated with biplanar external fixation before definitive fixation. A total of 26 patients (31%) were discharged to skilled nursing facilities, and 37 patients (43%) were not discharged between procedures. Total cost for a 30-day episode of care was $22,113 ± 4056. External fixation components ($5952, 26.9%), length of hospital stay ($5606, 25.4%), discharge to skilled nursing facility (SNF) ($3061, 13.8%), and definitive fixation implants ($2968, 13.4%) contributed to the total cost. The following were associated with total cost: patient discharged to SNFs (P < 0.001), patient remaining inpatient after external fixation (P < 0.001), days of admission for open reduction internal fixation (ORIF) (P = 0.005), days spent with external fixation (P < 0.001), days in a SNF after ORIF (P < 0.001), and external fixation component cost (P < 0.001). CONCLUSIONS: External fixation component selection is the largest contributor to cost of a 30-day episode of care for high-energy bicondylar tibial plateau fractures. Reduction in cost variability may be possible through thoughtful use of external fixation components and care pathways. LEVEL OF EVIDENCE: Economic analyses Level IV.

Arthroscopically Assisted Percutaneous Screw Fixation of Tibial Plateau Fractures.

Tibial plateau fractures account for approximately 1% to 2% of fractures in adults1. These fractures exhibit a bimodal distribution as high-energy fractures in young patients and low-energy fragility fractures in elderly patients. The goal of operative treatment is restoration of joint stability, limb alignment, and articular surface congruity while minimizing complications such as stiffness, infection, and posttraumatic osteoarthritis. Open reduction and internal fixation with direct visualization of the articular reduction or indirect evaluation with fluoroscopy has traditionally been the standard treatment for displaced tibial plateau fractures. However, there has been concern regarding inadequate visualization of the articular surface with open tibial plateau fracture fixation, contributing to a fivefold increase in conversion to total knee arthroplasty2. In addition, the risk of wound complications and infection has been reported to be as high as 12%3,4. Knee arthroscopy with percutaneous, cannulated screw fixation provides a less invasive procedure with excellent visualization of the articular surface and allows for accurate reduction and fracture fixation compared with traditional open reduction and internal fixation techniques1. Recent studies of arthroscopically assisted percutaneous screw fixation of tibial plateau fractures have reported excellent early clinical and radiographic outcomes and low complication rates3,5,6. Description: This technique involves the use of both arthroscopy and fluoroscopy to facilitate reduction and fixation of the tibial plateau fracture. Through a minimally invasive technique, the depressed articular joint surface is targeted with use of preoperative computed tomography (CT) scans and intraoperative biplanar fluoroscopy. Reduction is then directly visualized with arthroscopy and fixation is performed with use of fluoroscopy. Lastly, restoration of the articular surface is confirmed with use of arthroscopy after definitive fixation. Modifications can be made as needed. Alternatives: The traditional method for fixation of displaced tibial plateau fractures is open reduction and internal fixation. Articular reduction can be visualized directly with an open submeniscal arthrotomy and an ipsilateral femoral distractor or indirectly with fluoroscopy. Rationale: Visualization of the articular surface is essential to achieve anatomic reduction of the joint line. Inspection of the posterior plateau is difficult with an open surgical approach. Arthroscopically assisted percutaneous screw fixation of a tibial plateau fracture may allow for improved restoration of articular surfaces through enhanced visualization. Less soft-tissue dissection is associated with lower morbidity and may result in less damage to the blood supply, lower rates of infection and wound complications, faster healing, and better mobility for patients. In our experience, this technique has been successful in patients with severe osteoporosis and comminution of depressed fragments. If total knee arthroplasty is required, we have also observed less damage to the blood supply and fewer surgical scars with use of this surgical technique. Expected Outcomes: Arthroscopically assisted percutaneous screw fixation of a tibial plateau fracture facilitates anatomical reduction through a less invasive approach. Patients undergoing this method of tibial plateau fracture fixation are able to engage earlier in rehabilitation2. Studies have shown early postoperative range of motion, excellent patient-reported outcomes, and minimal complications7,8. Important Tips: Arthroscopically assisted fixation can be applied to a variety of tibial plateau fractures; however, the minimally invasive approach is best suited for patients with isolated lateral tibial plateau fractures (Schatzker I to III) and a cortical envelope that can be easily restored. The cortical envelope refers to the outer rim of the tibial plateau. Fracture pattern and ligamentotaxis determine the cortical envelope, which can be evaluated on preoperative CT scans. In our experience, even depressed segments with a high degree of comminution may be treated with use of this technique with satisfactory results.Articular depression should be targeted with use of a preoperative CT scan and intraoperative fluoroscopy and arthroscopy.The surgeon should be careful not to "push up" in 1 small area; rather, a "joker" elevator or bone tamp should be utilized, moving anterior to posterior, which can be frequently assessed with arthroscopy.The intra-articular pressure of the arthroscopy irrigation fluid should be low (≤45 mm Hg or gravity flow), and the operative extremity should be monitored for compartment syndrome throughout the procedure. Acronyms and Abbreviations: ACL = anterior cruciate ligamentK-wires = Kirschner wiresORIF = open reduction and internal fixationAP = anteroposteriorCR = computed radiography.

Outcomes After Revision Fixation With Cement Augmentation for Failed Intertrochanteric Fracture Fixation in Older Adult Patients.

Introduction: Intertrochanteric (IT) fractures that fail fixation are traditionally treated with arthroplasty, introducing significant risk of morbidity and mortality in frail older adult patients. Revision fixation with cement augmentation is a relatively novel technique that has been reported in several small scale international studies. Here we report a clinical series of 22 patients that underwent revision fixation with cement augmentation for IT fracture fixation failure. Methods: This retrospective case series identified all patients that underwent revision intramedullary nailing from 2018 to 2021 at two institutions within a large metropolitan healthcare system. Demographics, injury characteristics, Charlson Comorbidity Index score, and surgical characteristics were extracted from the electronic medical record. Outcomes were extracted from the electronic medical record and included radiographic findings, pain, functional outcomes, complications, and mortality. Results: Average follow-up after revision surgery was 15.2 ± 10.6 months. Twenty patients (90.9%) reported improved pain and achieved union or progressive healing after surgery. Most of these patients regained some degree of independent ambulation (19 patients, 86.4%), with only 5 patients (22.7%) requiring increased assistance for their activities of daily living (ADLs). One-year mortality was 13.6% (3 patients). Of the 5 patients (22.7%) that experienced complications, 2 patients (9.1%) required revision hemiarthroplasty for subsequent fixation failure. The other 3 patients did well when complications resolved. Conclusions: Revision fixation with cement augmentation can be an effective, safe, cost-effective alternative to arthroplasty for the management of cases involving non-infected failed IT fracture fixation with implant cut-out or cut-through limited to the femoral head in older adult patients that have appropriate acetabular bone stock.

Unplanned Emergency and Urgent Care Visits After Outpatient Orthopaedic Surgery.

INTRODUCTION: This study sought to determine (1) incident risk, (2) chief report, (3) risk factors, and (4) total cost of unplanned healthcare visits to an emergency and/or urgent care (ED/UC) facility within 30 days of an outpatient orthopaedic procedure. METHODS: This was a retrospective database review of 5,550 outpatient surgical encounters from a large metropolitan healthcare system between 2012 and 2016. Statistical analysis consisted of measuring the ED/UC incident risk, respective to the procedures and anatomical region. Patient-specific risk factors were evaluated through multigroup comparative statistics. RESULTS: Of the 5,550 study patients, 297 (5.4%) presented to an ED/UC within 30 days of their index procedure, with 23 (0.4%) needing to be readmitted. Native English speakers, patients older than 45 years, and nonsmokers had significant reduced relative risk of unplanned ED or UC visit within 30 days of index procedure (P < 0.01). In addition, hand tendon repair/graft had the greatest risk incidence for ED/UC visit (11.0%). Unplanned ED/UC reimbursements totaled $146,357.34, averaging $575.65 per visit. DISCUSSION: This study provides an evaluation of outpatient orthopaedic procedures and their relationship to ED/UC visits. Specifically, this study identifies patient-related and procedural-related attributes that associate with an increased risk for unplanned healthcare utilization.
