Six-Month Outcomes Correlate with 10-Year Outcomes Following Hip Arthroscopy for Femoroacetabular Impingement Syndrome.

PURPOSE: To identify whether 6-month outcomes following hip arthroscopy for FAIS correlate with outcomes at minimum 10-year follow-up. METHODS: Patients who underwent primary hip arthroscopy for FAIS from 2012-2013 were reviewed and included if they had 6-month and minimum 10-year follow-up. Patient-reported outcome (PRO) measures included Hip Outcome Score Activities of Daily Living (HOS-ADL) and Sports-Specific (HOS-SS) subscales, modified Harris Hip Score (mHHS), and Visual Analog Scales for Pain (VAS-P) and Satisfaction (VAS-S). Six-month and 10-year outcome scores were compared and the relationships between 6-month and 1-, 2-, 5-, and 10-year outcome scores were analyzed using Pearson correlation coefficients (r). 6-month scores and clinically significant outcome (CSO) achievement were then compared to 10-year CSO achievement and reoperations, including revision hip arthroscopy and total hip arthroplasty (THA) conversion, using logistic regressions and Fisher's exact tests. RESULTS: Sixty patients (60.0% female, age: 36.0±12.2 years) were included. mHHS, VAS-P, and VAS-S significantly improved from 6-month to 10-year follow-up (p≤0.021), while HOS-ADL and HOS-SS did not (p≥0.072). There were significant correlations between 6-month and 10-year scores for HOS-ADL (r=0.505), HOS-SS (r=0.592), and mHHS (r=0.362, p≤0.022 for all), as well as significant correlations between 6-month and 1-, 2-, and 5-year scores (p<0.014, for all). 6-month HOS-ADL, HOS-SS, and mHHS were all significantly associated with their respective 10-year PASS achievement (p≤0.044). Furthermore, 6-month HOS-ADL and mHHS were significantly associated with THA conversion (p≤0.041). Comparable 6-month and 10-year minimal clinically important difference (96.5% vs. 97.8%, p=1.000) and patient acceptable symptom state (85.2% vs. 87.5%, p=1.000) achievement for any PRO was observed. CONCLUSION: Following hip arthroscopy for FAIS, patients' 6-month HOS-ADL and mHHS scores were significantly associated with their 10-year PROs, PASS achievement, and THA conversion; although, correlation strengths decreased with increasing time from surgery. LEVEL OF EVIDENCE: IV, case series.

Cartilage Defects Are Negatively Associated With Long-Term Hip Survivorship Following Contemporary Hip Arthroscopy for Femoroacetabular Impingement Syndrome: A Propensity-Matched Analysis at Minimum 10-Year Follow-Up.

PURPOSE: To identify the timing and risk factors associated with secondary surgery following primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) at 10-year minimum follow-up. METHODS: A prospectively collected clinical repository was evaluated for cases of primary hip arthroscopy for FAIS between January 2012 and February 2013 with minimum 10-year follow-up. Patients who underwent secondary surgery were propensity matched 1:4 to patients who did not undergo secondary surgery, controlling for age, sex, and body mass index (BMI). The groups were compared on demographics, radiographs, intraoperative findings, operative procedures, and patient-reported outcomes. A Kaplan-Meier survivorship curve was generated. Among the reoperation-free survivors, minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) achievement were recorded for Hip Outcome Score-Activities of Daily Living (HOS-ADL), Hip Outcome Score-Sports Specific (HOS-SS) subscales, modified Harris Hip Score (mHHS), 12-item international Hip Outcome Tool (iHOT-12), and Visual Analog Scale for Pain (VAS Pain). RESULTS: Twenty-four reoperation patients (67% female; age 40.1 ± 14.3 years; BMI 27.2 ± 5.5) were matched to 96 reoperation-free patients (62% female; age 37.0 ± 10.8 years; BMI 25.2 ± 4.7, P ≥ .111). Mean follow-up was 10.3 ± 0.2 years. No preoperative demographic differences were found between groups. The reoperation group showed more high-grade cartilage defects on the acetabulum and femoral head (33% vs 8%, P = .004; 29% vs 7%, P = .007). A bimodal distribution of time to reoperation was evidenced independent of the secondary surgery performed. Among the reoperation-free survivors, MCID and PASS achievement was as follows: HOS-ADL (69.1%, 62.1%), HOS-SS (69.9%, 74.4%), mHHS (73.3%, 58.1%), iHOT-12 (n/a, 63.8%), and VAS-Pain (80.2%, 62.6%). CONCLUSIONS: Patients requiring reoperation following primary hip arthroscopy for FAIS demonstrated more severe cartilage defects and a bimodal distribution of time to reoperation. LEVEL OF EVIDENCE: Level III, retrospective comparative case series.

The Promising 2-Year Performance of the Patient-Reported Outcomes Measurement Information System in Primary Hip Arthroscopy for Femoroacetabular Impingement Syndrome.

BACKGROUND: Minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) thresholds have been previously defined for the Patient-Reported Outcomes Measurement Information System (PROMIS) at 1-year follow-up in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome; however, the MCID and PASS thresholds are yet to be defined for the PROMIS at 2-year follow-up. PURPOSE: (1) To establish MCID and PASS thresholds for the PROMIS Pain Interference (PROMIS-PI) and PROMIS Physical Function (PROMIS-PF) at 2-year follow-up and (2) to correlate PROMIS scores with hip-specific patient-reported outcome measure (PROM) scores. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 3. METHODS: Patients undergoing primary hip arthroscopy for femoroacetabular impingement syndrome between August and November 2020 with preoperative and minimum 2-year postoperative data were identified. Collected scores included those for the PROMIS-PI, PROMIS-PF, Hip Outcome Score-Activities of Daily Living (HOS-ADL), Hip Outcome Score-Sports Subscale (HOS-SS), International Hip Outcome Tool-12 (iHOT-12), and visual analog scale (VAS) for pain. MCID thresholds were calculated using the distribution-based method and PASS thresholds using the anchor-based method. Pearson correlation coefficients were used to compare scores between PROMs. RESULTS: A total of 65 patients met the criteria for inclusion (72.3% female; mean age, 36.9 ± 13.5 years; mean body mass index, 26.2 ± 6.0). The mean follow-up was 25.3 ± 3.3 months. Significant preoperative to postoperative improvements were observed for all PROMs (P < .001). MCID thresholds and achievement rates were as follows: HOS-ADL, 10.1 and 75%, respectively; HOS-SS, 13.8 and 79%, respectively; iHOT-12, 14.0 and 67%, respectively; VAS pain, -13.8 and 78%, respectively; PROMIS-PI, -4.7 and 65%, respectively; and PROMIS-PF, 5.8 and 60%, respectively. PASS thresholds and achievement rates were as follows: HOS-ADL, 78.7 and 67%, respectively; HOS-SS, 76.4 and 62%, respectively; iHOT-12, 67.4 and 60%, respectively; VAS pain, 25.5 and 61%, respectively; PROMIS-PI, 57.0 and 65%, respectively; and PROMIS-PF, 45.6 and 58%, respectively. PROMIS-PI scores correlated most strongly with HOS-ADL (r = -0.836), HOS-SS (r = -0.767), and iHOT-12 (r = -0.719) scores and exhibited at least moderate correlations (r≥-0.595) with the other PROM scores. PROMIS-PF demonstrated moderate correlations with all the other PROM scores (r≥-0.586). Strong correlations were seen between the hip-specific PROM scores (r≥-0.745). CONCLUSION: This study defined 2-year MCID and PASS thresholds for the PROMIS-PI and PROMIS-PF and demonstrated moderate to strong correlations between PROMIS scores and hip-specific PROM scores.

Patients Aged 40 Years and Older Demonstrate Durable and Comparable Results to Patients Aged Less Than 40 Years After Primary Hip Arthroscopy for Femoroacetabular Impingement Syndrome: A Propensity Matched Study at Minimum 10-Year Follow-Up.

PURPOSE: The purpose of the present study was to compare clinical outcomes and rates of secondary surgery, including revision hip arthroscopy and conversion to total hip arthroplasty (THA), after primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) in patients ≥40 years of age at minimum 10-year follow-up compared with a propensity-matched control group of patients <40 years. METHODS: A retrospective cohort study was performed for patients who underwent primary hip arthroscopy for FAIS between January 2012 and February 2013. Patients ≥40 years old were propensity matched in a 1:1 ratio by sex and body mass index to patients <40 years old. Patient-reported outcomes (PROs) including Hip Outcome Score for Activities of Daily Living and Sports-Specific subscales, modified Harris Hip, International Hip Outcome Tool-12, and Visual Analog Scale for Pain and Satisfaction were collected. Rates of minimal clinically important difference (MCID) and patient-acceptable symptomatic state (PASS) achievement at 10 years were evaluated and compared between groups. Rates of secondary surgery including revision hip arthroscopy and conversion to THA were evaluated. Gross survivorship between cohorts was evaluated using a Kaplan-Meier curve. RESULTS: Fifty-three patients aged ≥40 (age 48.3 ± 5.8 years) were successfully matched to 53 patients aged <40 (age: 28.9 ± 7.2, <0.001). There were no other preoperative group differences regarding patient demographics, characteristics, or radiographic findings. Both groups demonstrated significant improvement regarding all PROs at a minimum of 10 years' follow-up (P < .001 for all). No significant difference was noted between cohorts regarding any delta (preoperative to 10-year postoperative) scores (P > .05 for all). High rates of MCID and PASS achievement were achieved in both cohorts, with no significant differences in any PRO measure (P > .05 for all). No significant differences in rates of complications (age ≥40: 2.0%, age <40: 7.7%, P = .363), rates of revision (age ≥40: 7.5%, age <40: 9.4%, P = .999), or conversion to THA (age ≥40: 13.2%, age <40: 3.8%, P = .161) were identified. On Kaplan-Meier analysis, no significant difference (P = .321) was demonstrated in overall gross survivorship between cohorts. CONCLUSION: Patients with age ≥40 with FAIS undergoing primary hip arthroscopy demonstrated durable and comparable 10-year PRO and rates of MCID and PASS achievement compared with a propensity-matched cohort of age <40 counterparts. LEVEL OF EVIDENCE: Level III, retrospective comparative prognostic trial.

Acetabular Rim Disorders: Epidemiology, Etiology, Management, and Outcomes.

¼ Anatomic disorders of the acetabular rim are a common, correctable source of hip pain in younger patients.¼ Some common conditions of involving abnormal acetabular rim morphology include developmental dysplasia of the hip, pincer-type femoroacetabular impingement, acetabular protrusion, and acetabular retroversion.¼ Treatment option for these conditions were historically limited to open osteotomy and osteoplasty procedures; however, there is increasing use of arthroscopic intervention for these patients.¼ Arthroscopic intervention has demonstrated short-term success in a variety of focal acetabular rim disorders; however, further research is needed to determine the long-term outcomes of these procedures and their utility in more global pathology.

Editorial Commentary: Combined Anterior Cruciate Ligament Reconstruction and Medial Meniscal Transplantation Improve Functional Outcomes When Properly Indicated.

The anterior cruciate ligament (ACL) and medial meniscus both contribute to anteroposterior translation of the tibia. Biomechanical studies have found increased translation at both 30° and 90° when transecting the posterior horn of the medial meniscus, and clinically, medial meniscal deficiency has been shown to have a 46% increase in ACL graft strain at 90°. Medial meniscal deficiency is a risk factor for failure after ACL reconstruction, with a hazard ratio of 15.1. The combination of meniscal allograft transplantation and ACL reconstruction is technically demanding but results in mid- to long-term clinical improvement in well-indicated patients. Patients with medial meniscal deficiency and failed ACL reconstruction or with ACL deficiency and medial-sided knee pain due to meniscal deficiency are candidates for combined procedures. On the basis of our experience, acute meniscal injury is not an indication for primary meniscal transplantation in any setting. Surgeons should repair the meniscus if reparable or perform partial meniscectomy and see how the patient responds. There is insufficient evidence to show that early meniscal transplantation will be chondroprotective. We reserve this procedure for the indications previously described. Severe osteoarthritis (Kellgren-Lawrence grades III and IV) and Outerbridge grade IV focal chondral defects of the tibiofemoral compartment that are not amenable to cartilage repair are absolute contraindications to the combined procedure.

Epidemiology of Hand and Wrist Injuries in Collegiate-Level Athletes in the United States.

PURPOSE: Hand and wrist injuries are common among competitive athletes and can have a substantial impact on playing time and future participation. The purpose of this study was to provide epidemiological data from the National Collegiate Athletic Association Injury Surveillance Program to correlate injury diagnosis with the need for surgery and time loss. METHODS: Using the National Collegiate Athletic Association Injury Surveillance Program, this retrospective study extracted data of hand and wrist injuries for all 25 National Collegiate Athletic Association sports from the academic years 2004-2005 to 2013-2014. The "severe" category was defined as injuries resulting in the following: (1) surgery, (2) season-ending status, or (3) more than 30 days of playing time loss. The epidemiologic data included injury rate per 100,000 athlete exposures (defined as 1 athlete participating in 1 practice or competition) based on diagnoses and demographic information such as sports and sex. We used a Poisson regression model to estimate the incidence rate and 95% confidence interval. RESULTS: Overall, 4,851 hand injuries were identified, with an injury rate of 41.2 per 100,000 athlete exposures. The most common diagnoses were metacarpal or phalangeal fractures (19.9%), lacerations or contusions (15.4%), and wrist sprains (14.7%). The surgical rate was 9.6%, and the season-ending rate was 5.8%. Severe injuries occurred in 17.5% of the hand and wrist injuries; within this subset, the most common diagnoses included metacarpal or phalangeal fractures (43.8%), scaphoid fractures (12.8%), and thumb ulnar collateral ligament tears (8.7%). Scaphoid fractures and metacarpal or phalangeal fractures had the highest surgical rate and season-ending rate among all the injuries. CONCLUSIONS: The injury rate of hand and wrist injuries is comparable with those of other common sports injuries. Approximately one fifth of the injuries were considered severe, which led to a high surgical rate, and these had a considerable impact on the athletes' ability to finish the season. TYPE OF STUDY/LEVEL OF EVIDENCE: Outcome research level II.

The Outcomes of Intra-Articular Distal Humerus Open Reduction and Internal Fixation Using Parallel Precontoured Plates in the Elderly.

PURPOSE: Inconsistent outcomes have been reported in several prior studies of elderly patients with distal humerus fractures treated with open reduction and internal fixation (ORIF). We evaluated the outcomes of ORIF using modern precontoured plates exclusively in a parallel orientation. METHODS: A retrospective review was performed to identify the patients aged over 65 years who sustained an isolated distal humerus fracture between 2015 and 2019. We identified 22 patients who underwent distal humerus ORIF using parallel, precontoured locking plates. Electronic medical records were reviewed for demographic characteristics, physical examination findings, and radiographic data. Outcomes were assessed with Quick Disabilities of the Arm, Shoulder, and Hand scores and Mayo Elbow Performance scores. Complications were evaluated by a review of the patient's medical record and postoperative radiographs. RESULTS: Of the included patients, 18 were women and 4 were men; the average age was 78 years (SD, 8.5 years), and the patients were followed for an average of 33 months. The sample consisted of 19 AO type C, 1 type B, and 2 type A fractures. At the final follow-up, the mean arc of total elbow flexion was 107° (SD, 18.9°; range 40° to 130°), with mean elbow flexion of 129° (SD, 11.7°; range, 120° to 140°) and mean extension of 22° (SD, 12.9°; range 0° to 90°). The mean Quick Disabilities of the Arm, Shoulder, and Hand score was 19 (SD, 14.4), and the mean Mayo Elbow Performance score was 86 (SD, 10.2). Complications occurred in 5 (23%) patients, requiring 4 subsequent surgeries, of which 1 was a conversion to total elbow arthroplasty. CONCLUSIONS: Older patients who underwent ORIF of the distal humerus using a parallel construct demonstrated good functional outcomes and similar complications to those in previously reported studies. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Association of Drain Use in Ankle Arthrodesis With Increased Blood Transfusion Risk: A National Observational Study.

Background: Closed wound drainage has been extensively studied in the hip and knee arthroplasty literature with equivocal results on its clinical benefits. Although also used in orthopaedic surgeries like ankle arthrodesis and ankle arthroplasty, large-scale data are currently lacking on utilization patterns and real-world effectiveness. We, therefore, aimed to address this research gap in this distinct surgical cohort using national claims data. Methods: Using the Premier Healthcare claims database from 2006 to 2016, ankle arthrodesis (n=10,085) and ankle arthroplasty (n=4,977) procedures were included. The main effect was drain use, defined by detailed billing descriptions. Outcomes included blood transfusion, 90-day readmission, and length and cost of hospitalization. Mixed-effects models measured associations between drain use and outcomes. Odds ratios (OR, or % change), 95% CIs, and P values are reported. Results: Overall, drains were used in 11% (n=1,074) and 15% (n=755) of ankle arthrodesis and ankle arthroplasty procedures, respectively. Drain use dramatically decreased over the years in both surgery types: from 14% to 6% and 24% to 7% between 2006 and 2016, for arthrodesis and ankle arthroplasty procedures, respectively. After adjustment for relevant covariates, drain use was associated with increased odds of blood transfusion in ankle arthrodesis surgery (OR 1.4, CI 1.1-1.8, P = .0168), whereas differences that were statistically but not clinically significant were seen in cost and length of stay. In total ankle arthroplasty, no statistically significant associations were observed between drain use and the selected outcomes. Conclusion: This is the first national study on drain use in ankle surgery. We found a decrease in use over time. Drain use was associated with higher odds of blood transfusion in ankle arthrodesis patients. Although this negative effect may be mitigated by the rapidly decreasing use of drains, future studies are needed to discern drivers of drain use in this distinct surgical population. Level of Evidence: Level III, retrospective cohort study.

Economic impact of Comorbidities in Total Ankle Arthroplasty and Ankle Arthrodesis.

BACKGROUND: The demand for total ankle arthroplasty (TAA) and ankle arthrodesis surgery is increasing. Findings from other orthopaedic populations suggest an increasing comorbidity burden among those planned for surgery, however, data on TAA and ankle arthrodesis is limited. The goal of this study is to study the comorbidity burden for TAA and ankle arthrodesis. HYPOTHESIS: Comorbidity burden is associated with higher resource utilization for both TAA and ankle arthrodesis. PATIENTS AND METHODS: This retrospective cohort study utilized data from the nationwide Premier Healthcare Database (2006-2016) which contains inpatient claims on n=10,085 ankle arthrodesis and n=4,977 TAA procedures. Patients were categorized into Deyo-Charlson comorbidity index (DCCI) groups. Outcomes were cost of hospitalization, length of stay (LOS), total opioid utilization, discharge to a skilled nursing facility (SNF), and 30-day readmission. Mixed-effects models estimated associations between DCCI and outcomes. We report odds ratios (OR, or % change for continuous outcomes) and 95% confidence intervals (CI). RESULTS: In the TAA group, 67.9% of patients were in DCCI category 0 while 22.4%, 6.6%, and 3.1% were in the 1, 2, and >2 DCCI categories, respectively. This was 61.3%, 18.1%, 9.8% and 10.9% in the ankle arthrodesis group. The most common comorbidities were obesity, diabetes mellitus, and chronic pulmonary disease. Particularly in the ankle arthrodesis group, the proportion of patients with comorbidities has increased over time. After adjustment for relevant covariates, patients in the DCCI group >2 (compared to '0') were associated with stepwise effects of up to 77.1% (CI 70.9%; 83.6%) longer length of stay and up to 48.5% (CI 44.0%; 53.2%) higher cost of hospitalization. DISCUSSIONS: Comorbidity burden is increasing among patients undergoing ankle arthrodesis where it is associated with significantly increased resource utilization. Our data demonstrate the potential impact of patient selection, which may be crucial in optimizing preoperative status. LEVEL OF EVIDENCE: III.

Peripheral nerve block use in ankle arthroplasty and ankle arthrodesis: utilization patterns and impact on outcomes.

PURPOSE: Ankle arthrodesis and total ankle arthroplasty (TAA) are often associated with significant postoperative pain. While this may be mitigated by the use of peripheral nerve blocks (PNB), large-scale data are lacking. Using national data, we aimed to evaluate PNB utilization pattern and its impact on outcomes. METHODS: This retrospective cohort study utilized data from the nationwide database (2006-2016) on TAA (n = 5,290) and ankle arthrodesis (n = 14,709) procedures. PNB use was defined from billing; outcomes included opioid utilization, length and cost of stay, discharge to a skilled nurse facility, and opioid-related complications. Mixed-effects models estimated the association between PNB use and outcomes, separate by procedure type and inpatient/outpatient setting. We report odds ratios and 95% confidence intervals (CI). RESULTS: Overall, PNB was utilized in 8.7% of TAA and 9.9% of ankle arthrodesis procedures, with increased utilization from 2006 to 2016 of 2.6% to 11.3% and 5.2% to 12.0%, respectively. After adjustment for relevant covariates, PNB use was significantly associated with decreased total opioid utilization specifically in the inpatient setting in TAA ( - 16.9% CI  - 23.9%;  - 9.1%) and ankle arthrodesis procedures ( - 18.9% CI  - 24.4;  - 13.0%), this was particularly driven by a decrease in opioid utilization on the day of surgery. No clinically relevant effects were observed for other outcomes. CONCLUSION: PNB utilization is associated with substantial reductions in opioid utilization, particularly in the inpatient setting. Our study is in support of a wider use of this analgesic technique, which may translate into more benefits in terms of clinical outcomes and resource utilization. LEVEL OF EVIDENCE: III.

Surgical Management of Complex Adult Monteggia Fractures.

Monteggia fractures classically involve a proximal ulna fracture with an associated radial head dislocation. The presence of radial head/neck fracture and comminution of the proximal ulna with coronoid involvement elevates the complexity of surgical reconstruction considerably. The Jupiter classification captures this injury pattern as a subgroup of Bado posterior Monteggia lesions. Access to the critical coronoid fragment can be problematic from the posterior approach and may result in tenuous reduction and fixation, directly affecting the functional outcome. Multiple operative techniques have been described to address the broad spectrum of injuries seen in Monteggia fractures. This article will cover commonly used fixation techniques for Monteggia fractures with a comprehensive literature review, including technical tips, outcomes, and complications.

Epidemiology of Severe Foot Injuries in US Collegiate Athletes.

BACKGROUND: The effects of foot injuries on collegiate athletes in the United States are of interest because of the short 5-year eligibility period in the National Collegiate Athletic Association (NCAA). PURPOSE: To discuss the epidemiology of severe NCAA foot injuries sustained over 10 years in 25 sports. STUDY DESIGN: Descriptive epidemiology study. METHODS: We utilized the NCAA Injury Surveillance System, which prospectively collects deidentified injury data for collegiate athletes. Severe injuries were classified as season- or career-ending injuries, injuries with >30-day time loss, or injuries requiring operative treatment. Injury rates (IRs) were analyzed per 100,000 athlete-exposures. RESULTS: Of 3607 total foot injuries, 18.71% (n = 675) were classified as severe, with an IR of 5.73 per 100,000 athletic-exposures. For all severe injuries, the operative rate was 24.3%, the season-ending rate 37.0%, and the career-ending rate 4.4%. The proportion of recurrent injuries was 13.9%. Men's sports with the highest severe foot IRs were basketball (IR = 10.71), indoor track (IR = 7.16), and football (IR = 7.08). Women's sports with the highest severe foot IRs were cross-country (IR = 17.15), gymnastics (IR = 14.76), and outdoor track (IR = 14.65). Among all severe foot injuries, the most common was a fifth metatarsal fracture. The highest contact/noncontact injury ratios were phalangeal fracture, turf toe, and Lisfranc injury. The severe injuries with the highest operative rates were Lisfranc injuries, fifth metatarsal fractures, and midfoot fractures. The severe injuries associated with the highest season-ending IRs were Lisfranc injury, midfoot fracture, and general metatarsal fractures. Severe flexor/extensor injuries had the highest career-ending IRs, followed by turf toe. Severe injuries with the highest median time loss were sesamoidal fractures, calcaneal fractures, and plantar fascial injuries. CONCLUSION: Of all collegiate foot injuries sustained over a 10-year period, 18.7% were characterized as severe, and 24.3% of severe injuries required surgery. Basketball was the men's sport with the highest severe IR, and cross-country was the women's sport with the highest severe IR. Overall, female athletes experienced slightly higher severe foot IRs as compared with male athletes.

Enhanced Recovery After Surgery Protocols in Lower Extremity Joint Arthroplasty: Using Observational Data to Identify the Optimal Combination of Components.

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols are increasingly used in orthopedic surgery. Data are lacking on which combinations of ERAS components are (1) the most commonly used and (2) the most effective in terms of outcomes. METHODS: This retrospective cohort study utilized claims data (Premier Healthcare, n = 1,539,432 total joint arthroplasties, 2006-2016). Eight ERAS components were defined: (A) regional anesthesia, (B) multimodal analgesia, (C) tranexamic acid, (D) antiemetics on day of surgery, (E) early physical therapy, and avoidance of (F) urinary catheters, (G) patient-controlled analgesia, and (H) drains. Outcomes were length of stay, "any complication," and hospitalization cost. Mixed-effects models measured associations between the most common ERAS combinations and outcomes. Odds ratios (ORs) and 95% confidence intervals (CIs) are reported. RESULTS: In 2006-2012 and 2013-2016, the most common ERAS combinations were B/D/E/F/G/H (20%, n = 172,397) and B/C/D/E/F/G/H (17%, n = 120,266), respectively. The only difference between the most commonly used ERAS combinations over the years is the addition of C (addition of tranexamic acid to the protocol). The most pronounced beneficial effects in 2006-2012 were seen for combination A/B/D/E/F/G/H (6% of cases vs less prevalent ERAS combinations) for the outcome of "any complication" (OR 0.87, CI 0.83-0.91, P < .0001). In 2013-2016, the strongest effects were seen for combination B/C/D/E/F/G/H (17% of cases) also for the outcome of "any complication" (OR 0.86, CI 0.83-0.89, P < .0001). Relatively minor differences existed between ERAS protocols for the other outcomes. CONCLUSION: Despite varying ERAS protocols, maximum benefits in terms of complication reduction differed minimally. Further study may elucidate the balance between an increasing number of ERAS components and incremental benefits realized. LEVEL OF EVIDENCE: III.

Impact of COVID-19 Pandemic on Patients' Perceptions of Safety and Need for Elective Foot and Ankle Surgery in the United States.

BACKGROUND: With the development of the COVID-19 pandemic, elective foot and ankle surgeries were delayed throughout the United States to divert health care resources and limit exposure. Little is known about the impact of COVID-19 on patient's willingness to proceed with elective procedures once restrictions are lifted and factors contributing to such decision. METHODS: Patients across 6 US orthopedic institutions who had their elective foot and ankle surgeries cancelled secondary to the pandemic were given a questionnaire. Specifically, patients were asked about their willingness to move forward with surgery once restrictions were lifted and if not why. Pain-level and pain medication use were also assessed. Univariate analysis was used to identify factors that contribute to patient's decisions. RESULTS: A total of 150 patients participated in this study. Twenty-one (14%) opted not to proceed with surgery once restrictions were lifted. Forty-three percent (n = 9) listed concern for COVID infection as the reason; however, 14% of them would proceed if procedures were performed in surgery center. Twenty-nine (19% of the total cohort) patients had increased pain and 11% of patients were taking more pain meds because of the delay to their procedure. Patients who decided not to proceed with surgery reported pain reduction (3% vs 14%) and lower increase in pain medication used (5% vs 12%). CONCLUSION: COVID-19 has made a significant impact on the health care system. Delay of elective foot and ankle procedures impact patient quality of life and outcomes. Access to surgery centers may provide a partial solution during the pandemic. LEVEL OF EVIDENCE: Level III.

Peripheral nerve block use in inpatient and outpatient shoulder arthroplasty: a population-based study evaluating utilization and outcomes.

BACKGROUND: Peripheral nerve block (PNB) is an effective pain management option after shoulder arthroplasty with increasing popularity over the past decade. Large-scale US data in shoulder arthroplasties are lacking, especially regarding impacts on opioid utilization. This population-based study aimed to evaluate PNB utilization patterns and their effect on outcomes after inpatient and outpatient shoulder arthroplasty. METHODS: This retrospective cohort study used data from the nationwide Premier Healthcare claims database (2006-2016). This study includes n=94 787 and n=3293 inpatient and outpatient (total, reverse and partial) shoulder arthroplasty procedures. Multivariable mixed-effects models estimated associations between PNB use and opioid utilization in oral morphine equivalents and cost of hospitalization/stay. For the inpatient group, additional outcome measures were length of stay (LOS), admission to a skilled nurse facility, 30-day readmission, combined complications and naloxone use (as a proxy for opioid-related complications). We report OR (or % change for continuous variables) and 95% CIs. RESULTS: Overall, PNB was used in 19.1% (n=18 144) and 20.8% (n=685) of inpatient and outpatient shoulder arthroplasties, respectively, with an increasing trend for inpatient procedures. PNB utilization was consistently associated with lower (up to -14.0%, 95% CI -15.4% to -12.5% decrease, with median 100 and 90 oral morphine equivalents for inpatient and outpatient procedures) opioid utilization on the day of surgery with more potent effects seen for inpatient shoulder arthroplasties. Other outcomes were minimally impacted. DISCUSSION: In this first national study on PNB use in shoulder arthroplasty, we found increasing PNB use among specifically, inpatient procedures, resulting in particularly reduced opioid use on the day of surgery. While our findings may support PNB use in shoulder arthroplasty, its current low utilization and trends towards more outpatient procedures necessitate continuous monitoring of more extensive benefits.

DVT and Pulmonary Embolism Following Knee Arthroscopy: The Role of Genetic Predisposition and Autoimmune Antibodies: A Report of 3 Cases.

Deep vein thrombosis (DVT) after arthroscopy has been considered a rare event; however, recent studies using ultrasound and venography have shown that the incidence of DVTs is underestimated. CASES:: This report describes 3 patients with DVT and/or PE after knee arthroscopy who were attributed to a genetic predisposition of hypercoagulability unknown to the patient and surgeon. CONCLUSIONS:: Genetic predisposition and autoimmune antibodies may play a role in the development of DVT after knee arthroscopy. We recommend focused questions regarding family history be added to the standard DVT/PE preoperative questionnaire.

Opioid Consumption and Time to Return to Work After Percutaneous Osteotomy in Foot Surgery.

Surgeries involving the foot and ankle are painful procedures, with many patients unwilling to discontinue prescribed narcotics at 3 months postoperatively. Percutaneous techniques allow for smaller incisions and minimal soft tissue disruption. Fifty consecutive patients underwent outpatient percutaneous foot surgery. Data were collected on pain medication taken and time to return to work. A mean of 3.3 tablets of oxycodone were consumed during the first 2 weeks. No patient was taking narcotics after 2 weeks. Mean time to return to work was 18.9 days. Percutaneous foot and ankle surgery led to a significant reduction in narcotic consumption. [Orthopedics. 2020;43(4):e334-e337.].

Factors influencing treatment recommendations for base of 5th metatarsal fractures in orthopaedic residency programs.

BACKGROUND: Management of proximal 5th metatarsal fractures remains a controversial topic in orthopaedic surgery. Both operative and non-operative approaches have been described in the clinical setting. This confusion has led to non-standardized treatment recommendations for proximal 5th metatarsal fractures. This study was designed to analyze concordance rate of treatment recommendations between orthopaedic trainees and orthopaedic foot and ankle experts. METHODS: An online survey containing 14 cases of proximal 5th metatarsal fractures were distributed to 92 orthopaedic residents in two ACGME-accredited programs. Relevant weight-bearing radiographs, patient's age and gender were provided, and two questions regarding treatment recommendations were surveyed. Resident's recommended treatment was then matched against ultimate treatment by orthopaedic foot and ankle experts. ANOVA and T-test are used for associations between the rate of concordant treatment with PGY and trainee foot and ankle experience. Fleiss' kappa was used to assess the inter-observer agreement. RESULTS: Seventy-two residents returned the survey. The overall concordance rate was 43.98% with no correlation between agreement rate and PGY-years. No difference in agreement rate was observed between residents who had completed their foot and ankle rotation versus those who had not. There was a slight inter-observer agreement in recommending treatment among all residents (κ=0.117, 95% CI: 0.071-0.184). CONCLUSIONS: Our data demonstrated no significant concordance between resident level in training regarding proximal 5th metatarsal fracture treatment decisions, nor between residents and subspecialty-trained foot and ankle surgeons. Increased rotations with foot and ankle fellowship-trained surgeons throughout residency may be desirable to improve the quality of residency training. LEVEL OF EVIDENCE: III.

Percutaneous Zadek osteotomy for the treatment of insertional Achilles tendinopathy.

BACKGROUND: Insertional Achilles tendinopathy (IAT) is a challenging common lower extremity disorder, despite several treatment options described in literature. Open dorsal closing wedge calcaneal osteotomy or Zadek Osteotomy (ZO), for the treatment of the IAT has good clinical results but a high rate of postoperative complications. The purpose of this study is to describe percutaneous ZO for the treatment of the IAT and to evaluate its impact on the clinical and functional postoperative outcomes. METHODS: Twenty-six consecutive patients presenting with unilateral IAT refractory to nonoperative measures were treated with percutaneous ZO. Visual Analogue Scale (VAS) and Foot Function Index Score (FFI) were recorded preoperatively and at final follow-up visit (12±3) months. Postoperative complications, satisfaction, and relief of the pain were also recorded. RESULTS: The percutaneous ZO showed a significant improvement (p<0.0001) in preoperative to postoperative FFI (from 65±9 to 8±12) and VAS (from 9±1 to 1±2). Two postoperative complications (8%) were observed: a case of symptomatic non-union and hardware pain, both in healthy patients. The overall rate of satisfaction after surgery was (92%). The relief from pain was achieved after an average period of 12 weeks. CONCLUSIONS: ZO is a safe and effective procedure for the treatment of IAT. The use of a minimally invasive surgical approach is associated with excellent pain reduction (VAS score) and improved clinical function (FFI score). When compared to the open surgical approach, the percutaneous ZO may decrease recovery time and postoperative complications. LEVEL OF EVIDENCE: III, retrospective case series.
