RESUMEN
BACKGROUND: Total hip arthroplasty (THA) has become a common intervention for human immunodeficiency virus (HIV)-positive patients who have osteonecrosis of the femoral head. This paper provides a systematic review to assess survivorships, patient-reported outcomes (PROMs), infection rates, other complications, and immune competence for patients who had THAs who did and did not have HIV. METHODS: A comprehensive and systematic review of published studies investigating the outcomes of THA in HIV-positive patients (osteonecrosis and non-osteonecrosis patients) was performed adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 10 studies with 9,534 HIV-positive patients fulfilled the inclusion and exclusion criteria. Manuscript quality was assessed on 2 scales: the Coleman Methodology Score and the level of evidence derived from Center for Evidence-Based Medicine criteria. Data were extracted from studies in the 5 key areas of interest: survivorships, PROMs, infection rates, complications, and clusters of differentiation-4 (CD4+) counts and viral loads. RESULTS: Implant survivorship was between 95% and 100%. Postoperative Harris Hip Scores were significantly improved from preoperative values in HIV-positive patients. Postoperative PROMs and infections did not appear to be different between HIV-positive and HIV-negative patients. Many of the cohort studies demonstrate comparable complication rates to matched controls. Where described (7 reports), mean CD4+ counts ranged from 425 to 646 cells/mm3, with low viral loads (3 reports) and variations not found to influence outcomes. CONCLUSIONS: THA is an effective treatment for HIV-positive patients, many of whom suffer from osteonecrosis of the femoral head. The results demonstrate excellent implant survivorship, improved quality of life, and a low risk of infections and complications.

PURPOSE: To provide an update of recent literature with a specialized focus on clinical outcomes following arthroscopic revision Bankart repair (ARBR) by performing a systematic review of all available literature published between 2013 and 2020. METHODS: A literature search reporting clinical outcomes after ARBR was performed. Criteria for inclusion consisted of original studies; Level of Evidence of I-IV; studies focusing on clinical outcomes after ARBR published between January 1, 2013, and January 4, 2021; studies reporting recurrent dislocation or instability rate after ARBR; reoperation/revision following ARBR, return to sport rates following ARBR; and patient-reported outcomes. The primary outcomes of interest were failure defined as recurrent instability or dislocation, return to sport rates, and patient-reported outcomes at follow-up. RESULTS: A large proportion of patients undergoing arthroscopic revision Bankart repair were male, ranging between 67.7% and 93.8%. Failure rate and return to sports rate ranged between 6.1% and 46.8% and 25.9% and 88.3%, respectively, when patients with significant or greater than 20% glenoid bone loss was excluded. Patient-reported outcome scores, which included American Shoulder and Elbow Surgeons, Simple Shoulder Test, and visual analog scale, saw significant improvement over mean follow-up of ranging 21.64 to 60 months. CONCLUSIONS: Both the failure rate and RTS rates after ARBR had a wide range, given the heterogeneity of the studies included, which varied in patient selection criteria pertaining to patients with greater than 20% glenoid bone. Although there have been advancements in arthroscopic techniques and a trend favoring arthroscopic stabilization procedures, there is a lack of consensus in recent literature for careful patient selection criteria that would minimize failure rates and maximize RTS rates after ARBR. LEVEL OF EVIDENCE: Level IV, a systematic review of Level III-IV studies.

INTRODUCTION: A novel technique using an adjustable-loop cortical suspension toggle device for reduction of a fibular head avulsion fracture (arcuate fracture) in posterolateral corner (PLC) reconstruction is described. Results of clinical follow-up are presented. MATERIALS AND METHODS: 9 patients were retrospectively identified who underwent posterolateral corner reconstruction using an adjustable-loop cortical suspension toggle device. Radiographic examination was used to evaluate the successful healing of the avulsed fibular head fragments post-operatively. RESULTS: 7 patients reported satisfactory results with their clinical outcome with no feelings of knee instability or objective instability on exam at final follow-up. Post-operative radiographs obtained > 6 months following reconstruction demonstrated well reduced and healed fracture in 5 of 6 patients, with 1 patient demonstrating maintained reduction but incomplete fracture union at 6 months. CONCLUSION: This novel surgical technique for PLC reconstruction with an avulsed fibular head fracture is a viable alternative to previously described methods. The majority of patients report subjective satisfaction with a stable knee post-operatively. LEVEL OF EVIDENCE: IV.

PURPOSE: We sought to determine the rate of intraoperative and early postoperative (90-day) complications of multiligamentous knee reconstruction surgeries, both medical and surgical, and associated variables from the 15-year experience of a single academic institution. METHODS: Patients treated at a single academic institution between 2005 and 2019 who underwent multiligament knee surgery were identified. Inclusion criteria included intervention with 2+ ligament reconstructions performed concurrently, and more than 90 days postoperative follow-up. Exclusion criteria included revision ligamentous knee surgery. Patient demographics, mechanism of injury, and associated injuries of patients with intraoperative and postoperative complications, time from injury to multiligamentous knee reconstruction, and surgical data, including tourniquet time, procedure time, and type of procedures performed were retrospectively recorded. RESULTS: 301 knees in 296 patients met the eligibility criteria. There were 11 intraoperative complications in 9 knees (rate of 3%) and 136 postoperative complications in 90 knees (rate of 30%). Shorter time from injury to date of surgery was associated with arthrofibrosis (P = .001) and superficial wound infections (P = .015). Concurrent head injuries were associated with less complications (P = .029). Procedural time >300 minutes was associated with intraoperative blood transfusions (P > .05), deep infections (P = .003) and arthrofibrosis (P = .012). Inside-out meniscal repair was associated with superficial and deep infections (P = .006 and .0004). Tibial-based posterolateral corner (PLC) reconstruction was associated with symptomatic hardware (P = .037) and arthrofibrosis (P = .019) in comparison with fibular-based PLC reconstruction. Posterior cruciate ligament (PCL) reconstruction was associated with deep infections (P = .015), arthrofibrosis (P = .003), and postoperative blood transfusions (P = .018). CONCLUSION: Our 15-year data reveal there is a low intraoperative complication rate and high early postoperative complication rate with multiligamentous knee surgery. Surgeons should be wary of the increased intraoperative and postoperative complications associated with longer procedure times, inside-out meniscal repair, tibia-based PLC reconstruction, PCL reconstruction, and shorter time to surgery. LEVEL OF EVIDENCE: Case series: IV.

PURPOSE: To determine the reoperation rate, risk factors for reoperation, and patient-reported outcomes after isolated or combined tibial tubercle transfer and medial patellofemoral ligament reconstruction, for patellofemoral instability surgery. METHODS: Patient's records who underwent medial patellofemoral ligament reconstruction and/or tibial tubercle transfer for patellar instability by 35 surgeons from 2002 to 2018 at a single academic institution were retrospectively reviewed using CPT codes. Four-hundred-and-eighty-six patients were identified. Radiographic measurements, demographic parameters, and subsequent revision procedures and their indications were identified. A modified anterior knee pain survey was conducted by mail and with follow-up phone survey. RESULTS: The overall rate of reoperation was 120/486 (24.7%). The most common cause for reoperation was removal of hardware 42/486 (8.6%). The rate of reoperation for isolated medial patellofemoral ligament reconstruction 43/226 (19%) was lower than that of isolated tibial tubercle transfer 45/133 (33.8%) or a combined procedure 32/127 (25.2%) (P = 0.007). Woman had a higher rate of reoperation (29.4%) compared to men (15.9%) (P = 0.002). Patients at risk for a revision stabilization procedure included those with severe trochlear morphology (C or D) (6.1%) and those with Caton-Deschamps index > 1.3 (7.3%). Patients who underwent reoperation of any kind had poorer patient-reported outcomes. CONCLUSION: The overall reoperation rate after patellofemoral instability surgery remains high, and any reoperation portends worse patient-reported outcomes. Re-operations for instability are more likely in patients with trochlear dysplasia and patella alta and may benefit from more aggressive initial treatment, such as medial patellofemoral ligament reconstruction and tibial tubercle transfer in combination. Using the results of this study, surgeons will be able to engage in meaningful discussion with patients to counsel patients on expectations postoperatively. LEVEL OF EVIDENCE: IV.

The benefits of denosumab as an antiresorptive therapy and in reducing fragility fractures are well documented. However, its association with atypical femur fractures (AFFs), especially in the absence of prior bisphosphonate use, remains poorly understood and warrants further investigation. This case report presents a rare instance of bilateral AFFs in a 78-year-old bisphosphonate-naïve patient with a history of long-term denosumab therapy for previous metastatic breast cancer. Management involved intramedullary nail fixation after initial presentation with a unilateral AFF and a recommendation to cease denosumab therapy. However, the patient subsequently experienced a contralateral periprosthetic AFF below a total hip implant 5 months thereafter and was treated with open reduction internal fixation. This case report highlights the critical need for orthopedic surgeons to maintain a high level of suspicion and vigilance in screening for impending AFFs, especially in patients with a prolonged history of denosumab therapy without prior bisphosphonate use. Furthermore, the growing report of such cases emphasizes the urgent need for comprehensive research aimed at refining treatment protocols that balance the therapeutic benefits of denosumab and its associated risks of AFFs.
RESUMEN
Background: Total knee arthroplasty (TKA) has become a common surgical intervention for human immunodeficiency virus (HIV)-positive patients who develop osteonecrosis of the knee. This paper summarized existing literature regarding the outcomes of HIV-positive patients undergoing TKA in 4 subsections: (1) complications; (2) survivorship analyses; (3) patient-reported outcomes; and (4) infections. Methods: A review of PubMed was performed, searching for articles focused on HIV-positive patients undergoing TKA. There were 6 reports selected, containing 4765 HIV-positive patients, and data regarding the various domains was tabulated and analyzed. To ensure article quality, a methodology score and level of evidence were determined for selected studies. Results: Complication rates for HIV-positive patients were low, with a larger study reporting that 7.8% of HIV-positive patients developed a complication in comparison to 8% of HIV-negative patients. Survivorship analyses showed similar results, with a study reporting implant survivorship of 98% for HIV-positive and 99% for HIV-negative patients. There were no differences in patient-reported outcomes; HIV-positive patients improved from baseline with respect to the mean Knee Society objective and mean Knee Society functional scores, and the University of California, Los Angeles self-reported activity levels. The infection rate for HIV-positive patients was low, with a larger database study reporting that 0.6% of HIV-positive patients developed a wound infection in comparison to 0.4% of HIV-negative patients. Conclusions: A TKA is an effective treatment for HIV-positive patients who develop osteonecrosis of the knee. Results showed similar patient-reported outcomes, implant survivorships, revisions, and complication rates when compared to non-HIV patients.
RESUMEN
OBJECTIVES: To compare acute outcomes between patients undergoing fix and replace (FaR) versus open-reduction and internal fixation (ORIF) alone in the treatment of geriatric acetabular fractures. DESIGN: Retrospective Cohort Study. SETTING: Single Level 2 Trauma Center. PATIENT SELECTION CRITERIA: Consecutive acetabular fracture patients ≥ 55 years of age treated by two orthopaedic trauma surgeons at one tertiary care center from January 2017 to April 2022 with FaR versus ORIF were identified. Included were those with complete datasets within the 180-day global period. Excluded were patients with previous ORIF of the acetabulum or femur, or revision total hip arthroplasty. OUTCOME MEASURES AND COMPARISONS: The primary outcomes were length of hospital stay (LOS), postoperative weight-bearing status, postoperative disposition, time to postoperative mobilization, and 90-day readmission rates. Secondary outcomes compared included demographic information, injury mechanism, surgical time, complications, revisions, and preoperative and postoperative Hip Disability and Osteoarthritis Outcomes Score for Joint Replacement (HOOS Jr.) scores. These were compared between FaR and ORIF groups. RESULTS: Seventeen FaR patients (average age 74.5 ± 9.0 years) and 11 ORIF patients (average age 69.4 ± 9.6 years) met inclusion criteria. Mean follow-up was 26.4 months (range: 6-75.6 months). More FaR group patients were ordered immediate weight-bearing as tolerated or partial weight-bearing compared with ORIF alone (70% vs. 9.0%, P = 0.03). More patients in the FaR group had pre-existing hip osteoarthritis compared with ORIF alone (71% vs. 27%, P = 0.05). Fracture classification ( P = 0.03) and Charlson Comorbidity Index ( P = 0.02) differed between the 2 groups. There were no other differences in demographics, LOS ( P = 0.99), postoperative disposition ( P = 0.54), time to postoperative mobilization ( P = 0.38), 90-day readmission rates ( P = 0.51), operative time ( P = 0.06), radiographic union ( P = 0.35), time to union ( P = 0.63), pre- ( P = 0.32) or postoperative HOOS Jr. scores ( P = 0.80), delta HOOS Jr. scores ( P = 0.28), or reoperation rates between groups ( P = 0.15). CONCLUSIONS: FaR and ORIF seem to be sound treatment options in the management of geriatric acetabular fractures. Patients in the FaR group achieved immediate or partial weight-bearing earlier than the ORIF group; however, time to postoperative mobilization did not differ between the two groups. The remainder of acute postoperative outcomes (LOS, postoperative disposition, and 90-day readmission rates) did not differ between the two groups. LEVEL OF EVIDENCE: Therapeutic Level III.

BACKGROUND: Rehabilitation after anterior cruciate ligament ACL reconstruction (ACLR) is crucial for safe return to play (RTP) and reducing the chances of a reinjury. Yet, there is no consensus on the ideal functional tests to assess rehabilitation progress in soccer players after ACLR. PURPOSE: The primary objective was to highlight the existing gap in the literature concerning the most effective standardized rehabilitation protocols and testing for facilitating successful RTP among soccer players. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic review using PubMed, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL) was conducted. Inclusion criteria encompassed original studies (level of evidence 1-4) that examined rehabilitation protocols, metrics of knee rehabilitation, and clinical outcomes after ACLR in soccer players. RESULTS: This review incorporated 23 studies, predominantly retrospective case series, with a total number of 874 soccer players who underwent ACLR and rehabiliation. 5 (21.7%) studies utilized an accelerated rehabilitation protocol, while 7 (30.4%) of studies utilized a criterion-based rehabilitation. A wide heterogeneity of data was extracted including functional tests of rehabilitation and RTP such as strength test batteries, hop test batteries, and movement quality assessments. Of the 23 selected studies, 2 (8.7%) used all 3 test batteries, 8 (34.8%) used 2 test batteries, 12 (52.2%) used 1 test battery, and 1 (4.3%) used 0 of the test batteries. The mean time between surgery and RTP ranged from 3 to 8 months with only 2 (8.7%) studies reporting complications after ACLR. Lastly, out of the total studies examined, 9 (39.1%) assessed patient-reported outcome measures (PROMs), all of which demonstrated significant improvement from the initial assessment to the final follow up. CONCLUSION: Soccer-specific rehabilitation after ACLR lacks standardization. Even though many studies have assessed protocols for optimal RTP and reduced secondary ACL injuries, there is a gap in the literature regarding the most effective protocols and RTP testing. The methodology reported by Kyritsis et al could serve as a foundation for future prospective randomized multicenter studies to establish a standard rehabilitation protocol and enable a successful return to soccer.
RESUMEN
Background: Periprosthetic joint infection after total knee arthroplasty is commonly treated via 2-stage revision utilizing either articulating or static antibiotic cement spacers. While recent literature exhibits a slight functional advantage in favor of articulating spacers, those patients with a history of recurrent infection/multiple revision procedures are frequently excluded from these studies. The purpose of this study was to report infection eradication rates and efficacy of utilizing antibiotic-loaded locked intramedullary nail for infection for the multiply revised, infected total knee arthroplasty. Methods: A retrospective review was performed of all consecutive patients receiving static spacers between 2017 and 2020 at an academic medical center. Surgical techniques for all patients included irrigation and debridement using a reamer-irrigator-aspirator, injection of antibiotic-loaded calcium sulfate into the intramedullary canal, and nail placement. Antibiotic-loaded cement is then used to create a spacer block in the joint space. A Cox proportional hazard regression was run to identify risk factors for reinfection. Results: Forty-two knees in 39 patients were identified meeting inclusion criteria. Overall, there was an 68.8% infection eradication rate at an average of 46.9 months following spacer placement. The only risk factors identified on cox regression were increasing number of previous spacers, a surrogate for previous infections (hazards ratio = 14.818, P value = .021), and increasing operative time during spacer placement (hazards ratio = 1.014, P value = .039). Conclusions: Use of static spacers, in conjunction with reamer-irrigator-aspirator and antibiotic-loaded calcium sulfate, can be effective in treating chronic, complex periprosthetic joint infections in the setting of bone loss and or soft-tissue compromise and produced similar results to more simple infection scenarios.
RESUMEN
Introduction: Delay to surgery >24 hours has been shown to correlate with mortality rates in patients with hip fracture when left untreated. Many of these patients have multiple comorbidities, including aortic stenosis (AS), and undergo workup for operative clearance, which may delay time to surgery. The purpose of this study was to examine whether preoperative echocardiogram workup affects time to surgery, complications, and mortality after operative fixation for hip fracture. Methods: Our institutional hip fracture registry was retrospectively reviewed for inclusion over a 3-year period. Patients who had a preoperative echocardiogram (yECHO) for operative clearance were compared with those who did not (nECHO). Demographic data, time to surgery, overall complication rate, and mortality at 30 days, 90 days, and 1 year were collected. Results: Two cohorts consisted of 136 yECHO patients (45.8%) and 161 nECHO patients (54.2%). Thirty-two yECHO patients (23.5%) had AS. Patients in the yECHO cohort were more likely to have a complication for any cause compared with nECHO patients (25.7% vs. 10.6%, P = 0.01) and have a higher mortality rate at 1 year (38.9% vs. 17.4%, P = 0.001). There was no association found between AS and all-cause complication (P = 0.54) or 30-day (P = 0.13) or 90-day mortality rates (P = 0.79). However, patients with AS had a significantly higher mortality rate at 1 year (45.8% vs. 25.1%, P = 0.03). Conclusion: This study reinforces the benefits of ensuring less than a 24-hour time to surgery in the setting of a hip fracture and identifies an area of preoperative management that can be further optimized to prevent unnecessary prolongation in time to surgery. Patients with known aortic stenosis are not associated with increased 30-day or 90-day mortality or all-cause complications. Surgical delays in the yECHO cohort were attributed to preoperative medical assessments, including echocardiograms and the management of comorbidities. Therefore, the selective utilization of preoperative echocardiograms is needed and should be reserved to ensure they have a definitive role in guiding the perioperative care of patients with hip fracture. Level of Evidence: III.
RESUMEN
INTRODUCTION: To analyze recent literature comparing clinical outcomes of displaced intra-articular calcaneal fractures (DIACF) treated with open reduction and internal fixation using the extensile lateral approach (ELA) vs the minimally invasive sinus tarsi approach (STA), with a focus on wound complications. MATERIALS AND METHODS: A comprehensive literature search was conducted utilizing PubMed, EMBASE, and Cochrane Library databases following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies published between 2013 and 2022, level of evidence (LOE) I-III, head-to-head comparative studies reporting on clinical outcomes after DIACFs treated with ORIF using ELA versus STA, and literature with full-text written in English were included. Data collection included: publication year, study design, number of surgeons, number of participants, demographic data (mean age at time of surgery, percent male, body mass index, medical co-morbidities), preoperative data (mechanism of injury, Sanders classification, time from injury to surgical fixation), intraoperative data, and postoperative clinical and radiographic outcomes (Böhler angle, angle of Gissane, calcaneal height/length/width). RESULTS: A total of 21 articles (4 randomized control trials, 17 cohort studies) comprising of 2086 patients with calcaneal fractures, treated with either ELA (n = 1129) or STA (n = 957) met inclusion criteria. The risk of postoperative wound-related complications (RR 2.82, 95 % CI: 2.00-3.98, I2=27 %) and the risk of reoperation (RR 1.85, 95 % CI: 0.69-5.00, I2=67 %) was higher in ELA patients comparted to STA patients. However, the increased risk of postoperative wound-related complications with an ELA vs. STA was shown to be trending downward in recent publications. The ELA group also experienced longer time to surgery, extended operative times, and prolonged hospital stays when compared to the STA group. Radiographic measurements at final follow-up, including Böhler angle, angle of Gissane, as well as calcaneal height, length, and width, showed no statistically significant differences between the two groups. CONCLUSION: Surgical treatment of calcaneal fractures utilizing the ELA continues to have an increased rate of complications and reoperation when compared to the less invasive STA, yet recent trends in the literature show that this rate is decreasing. Operative treatment of calcaneal fractures via either an ELA or STA can both achieve comparable postoperative radiographic outcomes. LEVEL OF EVIDENCE: Therapeutic Level III.

During acetabular cup positioning, intraoperative measurements of cup anteversion were taken using both fluoroscopy and navigation system. With the C-arm introduced at 40°, an anteroposterior view of the pelvis is taken. The C-arm is then centered over the hip, showing an anteverted cup with an approximate inclination of 40°. The axial C-arm is tilted away until the cup opening is visualized as a straight line, indicating that the beam of the fluoroscopy is aligned with the cup's anteversion. The tilt angle on the C-arm and anteversion reading on the navigation workstation were recorded. The high degree of agreement between fluoroscopic and navigation measurement of acetabular cup anteversion supports the use of fluoroscopy in settings with limited access to navigation systems in direct anterior total hip arthroplasty.
RESUMEN
Background: A novel hybrid transtibial (HTT) approach to femoral tunnel drilling in anterior cruciate ligament reconstruction (ACLR) has been developed that circumvents the need for knee hyperflexion and orients the graft in the most anatomic position without sacrificing the tunnel length or aperture. Hypothesis: Patients who underwent ACLR utilizing the HTT technique would achieve excellent patient-reported outcome scores and experience low rates of graft failure and reoperations. Study Design: Case series; Level of evidence, 4. Methods: Patients who underwent primary ACLR at a single institution between 2005 and 2020 were retrospectively reviewed. Patients treated with the HTT, anteromedial portal (AMP), and transtibial (TT) approaches were matched based on age, sex, and body mass index ±3 kg/m2. Demographic and surgical data as well as femoral tunnel angle measurements on anteroposterior and lateral radiographs were collected for the 3 groups. However, clinical outcomes were only reported for the HTT group because of concerns of graft heterogeneity. Results: A total of 170 patients (median age, 26.5 years [interquartile range (IQR), 18.0-35.0 years]) who underwent ACLR using the HTT approach were included. The median coronal- and sagittal-plane femoral tunnel angles were 47° (IQR, 42°-53°) and 40° (IQR, 34°-46°), respectively. The sagittal-plane femoral tunnel angles in the HTT group were significantly more horizontal compared with those in the TT group (P < .0001), whereas the coronal-plane femoral tunnel angles in the HTT group were found to be significantly more vertical compared with those in the AMP group (P = .001) and more horizontal compared with those in the TT group (P < .0001). The graft failure and reoperation rates in the HTT group at a minimum 2-year follow-up were 1.8% (3/170) and 4.7% (8/170), respectively. The complication rate was 6.5% (11/170), with the most common complication being subjective stiffness in 7 patients. The median Lysholm score was 89.5 (IQR, 79.0-98.0); the median International Knee Documentation Committee score was 83.9 (IQR, 65.5-90.8); and the median Veterans RAND 12-Item Health Survey physical and mental component summary scores were 55.0 (IQR, 52.6-55.9) and 56.2 (IQR, 49.1-59.3), respectively. Conclusion: ACLR using the HTT technique was associated with low graft retear and revision surgery rates and good patient-reported outcome scores at medium-term follow-up and demonstrated femoral tunnel obliquity on postoperative radiographs that correlated with optimal parameters previously reported in cadaveric and biomechanical studies.
RESUMEN
INTRODUCTION: The purpose of this systematic review and meta-analysis was to provide an update of the recent literature comparing clinical outcomes of surgically treated fibular fractures using intramedullary nailing (IMN) with open reduction and internal plate fixation (ORIF). METHODS: A literature search reporting clinical outcomes after IMN or ORIF of the distal fibula was conducted on PubMed. Inclusion criteria consisted of original studies; studies focusing on clinical outcomes after IMN or IMN and ORIF published before May 11, 2022; studies with at least 5 patients; and studies reporting union rates, complication rates, and patient-reported outcomes such as American Orthopaedic Foot and Ankle Society (AOFAS) and Olerud-Molander scores. RESULTS: Of 2,394 studies identified, a total of 29 studies (4 LOE-I, 2 LOE-II, 6 LOE-III, 17 LOE-IV) were included consisting of 1,850 IMN patients and 514 plate patients. The pooled mean age of IMN patients was 58 years (95% confidence interval [CI], 54 to 62, I2 = 42%) versus 57 years (95% CI, 53 to 62, I2 = 49%) in ORIF. Union rates for IMN patients revealed a 99% union rate (95% CI, 0.98 to 1.00, I2 = 20%) versus 97% union rate for ORIF patients (95% CI, 0.94 to 0.99, I2 = 0%). Studies that compared IMN with ORIF revealed no difference in union rates (risk ratio [RR] = 0.99, 95% CI, 0.96 to 1.02, I2 = 0%). IMN patients showed a 15% complication rate (95% CI, 0.09 to 0.23, I2 = 89%), whereas plate patients had a complication rate of 30% (95% CI, 0.18 to 0.46, I2 = 63%). When comparing studies with both treatments, IMN patients had a significantly lower risk of complications (RR = 0.49, 95% CI, 0.29 to 0.82, I2 = 50%). The IMN group trended toward a higher mean AOFAS and Olerud-Molander score than the plate group by 4.53 (95% CI, -14.58 to 23.65, I2 = 85%) and 3.54 (95% CI, -2.32 to 9.41, I2 = 76%) points, respectively. CONCLUSION: Current literature reveals near equivalence in union rates and a markedly lower risk of complications when comparing IMN with plate fixation. While IMN patients had higher AOFAS and Olerud-Molander scores, these differences were not statistically significant. Notably, subgroup analyses indicated that rates of symptomatic implant and removal of implant were comparable between IMN and ORIF, which may indicate that wound-related complications were reduced in the minimally invasive IMN technique. While the high cost of IMN implants remains a barrier to their widespread adoption, the long-term benefits of reducing complications, specifically associated with wound complications in high-risk populations, may greatly improve quality of care for patients with distal fibula fractures. Additional research and cost-effectiveness analyses are warranted to fully assess the long-term benefits and economic feasibility of using IMN fixation for distal fibula fractures. LEVEL OF EVIDENCE: Therapeutic Level IV.

OBJECTIVES: To determine if a multidisciplinary institutional protocol can optimize the time to antibiotic (Abx) administration for open fractures (openFx) and improve compliance with the administration of Abx prophylaxis during trauma activation. DESIGN: Retrospective pre-post study design. SETTING: Single Level II Trauma Center. PATIENT SELECTION CRITERIA: All patients who triggered a trauma activation with suspected openFx and were treated according to the institutional single antibiotic regimen were eligible for inclusion. Patients were excluded if fractures did not involve the appendicular skeleton. Patients treated before implementation of a standardized institutional protocol where premixed IV bags of antibiotics were stocked in automated dispensing systems within ED trauma bays (January 2021-October 2022) were defined as the "pre" group and those treated following implementation the "post" group. OUTCOME MEASURES AND COMPARISONS: The primary outcome was time from trauma bay arrival to antibiotic aministration, measured in minutes, with comparisons made between preprotocol and postprotocol implementation. Secondary outcomes for comparison included rates (%) of time to Abx <60 minutes, allergic reactions, acute kidney injury, ototoxicity, surgical site infection, multi-drug-resistant organisms identified in blood or biopsy cultures in cases requiring reoperation, and Clostridium difficile infection in the gastrointestinal system, confirmed by stool test results, within 30 days. RESULTS: Twenty-four patients (mean age 39.5 ± 16.3 years) met the criteria after protocol implementation compared with 72 patients (mean age 34.3 ± 14.8 years) before implementation. Implementation of the institutional protocol resulted in a significant reduction in the time to Abx administration for openFx from 87.9 ± 104.6 minutes to 22.2 ± 12.8 minutes in the postprotocol group ( P < 0.001). In addition, only 53% in the preprotocol group received Abx within 60 minutes compared with 96% in postprotocol group ( P < 0.001). Post hoc power analysis revealed that the study was powered at 92% (effect size = 0.72) to detect a significant difference between the preprotocol and postprotocol groups. CONCLUSION: This study provides evidence that a multidisciplinary institutional protocol for the administration of Abx prophylaxis can be an effective strategy for optimizing the time to Abx administration in cases of suspected openFx. This protocol may be implemented in other trauma centers to optimize time to Abx administration for openFx. LEVEL OF EVIDENCE: Therapeutic Level III.

This study aimed to describe the demographics, clinical outcomes, and radiologic outcomes of patients who underwent meniscal root repair at a single, large academic institution. Patients who underwent meniscal root repair between January 2011 and April 2015 were identified. Patient demographics, injury characteristics, and intraoperative findings of medial femoral condyle chondromalacia and other concomitant pathology were retrospectively recorded. Enrolled patients returned to clinic for prospectively collected International Knee Documentation Committee (IKDC) subjective and objective forms, knee radiographs, and magnetic resonance imaging (MRI). A total of 25 root injuries (23 patients) were included in the final analysis. Majority of root injuries were medial menisci (68%) and repaired using transosseous pull-out technique (80%). Most patients (65%) were male, relatively young (median age = 37 years), overweight (median body mass index [BMI] = 26 kg/m2), and reported a traumatic event associated with their injury (60%). Also, 36% (9/25) of root repairs were performed concomitantly with an anterior cruciate ligament (ACL) reconstruction; 100% (8/8) lateral meniscal root injuries were associated with a concomitant ACL injury compared with 6% (1/17) of medial root injuries. Overall, 53% (9/17) of medial meniscal root repairs were performed in the setting of high-grade (Outerbridge's grade III/IV) chondral pathology of the ipsilateral femoral condyle. Median follow-up was 16 months. The Kellgren-Lawrence radiographic scale progressed in two knees that underwent meniscal root repair based on comparison of preoperative to follow-up radiographs. MRI showed 88% (22/25) of meniscal roots had completely healed, 6% (1/17) of the medial root repairs showed evidence of extrusion, and 44% (11/25) of repairs were associated with progressive chondromalacia. All patients had normal or near normal IKDC objective scores at time of follow-up. Surgeons should have a high suspicion for concomitant ACL injuries in the setting of lateral meniscal root tears, and be wary of concomitant high-grade chondral damage in the setting of medial meniscal root tears. Most meniscal root repairs appeared completely healed with low rates of medial meniscal extrusion on MRI at short-term follow-up, despite a high rate of chondromalacia progression. Present study is a large case series with prospective follow-up and reflects level of evidence IV.

BACKGROUND: Traction tables have long been utilized in the management of fractures by orthopaedic surgeons. The purpose of this study was to systematically review the literature to determine the complications inherent to the use of a perineal post when treating femur fractures using a traction table. METHODS: A systematic review was conducted using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) using PubMed, EMBASE, and Cochrane Library. The search phrase used was "fracture" AND "perineal" AND "post" AND ("femur" OR "femoral" OR "intertrochanteric" OR "subtrochanteric"). Inclusion criteria for this review were: level of evidence (LOE) of I - IV, studies reporting on patients surgically treated for femur fractures, studies reporting on patients treated on a fracture table with a perineal post, and studies that reported the presence or absence of perineal post-related complications. The rate and duration of pudendal nerve palsy were analyzed. RESULTS: Ten studies (2 prospective and 8 retrospective studies; 2 LOE III and 8 LOE IV) were included consisting of 351 patients of which 293 (83.5%) were femoral shaft fractures and 58 (16.5%) were hip fractures. Complications associated with pudendal nerve palsies were reported in 8 studies and the mean duration of symptoms ranged between 10 and 639 days. Three studies reported a total of 11 patients (3.0%) with perineal soft tissue injury including 8 patients with scrotal necrosis and 3 patients with vulvar necrosis. All patients that developed perineal skin necrosis healed through secondary intention. No permanent complications relating to pudendal neurapraxia or soft tissue injuries were reported at final follow-up timepoints. CONCLUSION: The use of a perineal post when treating femur fractures on a fracture table poses risks for pudendal neurapraxia and perineal soft tissue injury. Post padding is mandatory and supplemental padding may also be required. Appropriate perineal skin examination prior to use is also important. Occurring at a higher rate than previously thought, appropriate post-operative examination for any genitoperineal soft tissue complications and sensory disturbances should not be ignored.
RESUMEN
INTRODUCTION: Indications for reverse total shoulder arthroplasty (rTSA) has expanded to encompass complex proximal humerus fractures (PHFs) in recent years. The purpose of this study was to report and assess whether PHF patients treated with rTSA could achieve similar functional outcomes and short-term survivorship to patients who underwent rTSA for rotator cuff arthropathy (RTCA). METHODS: All consecutive patients with a preoperative diagnosis of PHF or RTCA, 18 years or older, treated with rTSA at a single academic institution between 2018 and 2020 with a minimum 2-year follow-up were retrospectively reviewed. Primary outcomes were survivorship defined as revision surgery or implant failure analyzed using the Kaplan-Meier survival curve, and functional outcomes, which included Quick Disabilities of the Arm, Shoulder, and Hand, and range of motion (ROM) were compared at multiple follow-up time points up to 2 years. Secondary outcomes were patient demographics, comorbidities, surgical data, length of hospital stay, and discharge disposition. RESULTS: A total of 48 patients were included: 21 patients (44%) were diagnosed with PHF and 27 patients (56%) had RTCA. The Kaplan-Meier survival rate estimates at 3 years were 90.5% in the PHF group and 85.2% in the RTCA group. No differences in revision surgery rates between the two groups (P = 0.68) or survivorship (P = 0.63) were found. ROM was significantly lower at subsequent follow-up time points in multiple planes (P < 0.05). A greater proportion of patients in the PHF group received cement for humeral implant fixation compared with the RTCA group (48% versus 7%, P = 0.002). The mean length of hospital stay was longer in PHF patients compared with RTCA patients (2.9 ± 3.8 days versus 1.6 ± 1.8 days, P = 0.13), and a significantly lower proportion of PHF patients were discharged home (67% versus 96%, P = 0.015). CONCLUSION: The rTSA implant survivorship at 3 years for both PHF and RTCA patients show comparable results. At the 2-year follow-up, RTCA patients treated with rTSA were found to have better ROM compared with PHF patients.

BACKGROUND: Focal cartilage lesions of the knee remain a difficult entity to treat. Current treatment options include arthroscopic debridement, microfracture, autograft or allograft osteochondral transplantation, and cell-based therapies such as autologous chondrocyte transplantation. Osteochondral transplantation techniques restore the normal topography of the condyles and provide mature hyaline cartilage in a single-stage procedure. However, clinical outcomes comparing autograft versus allograft techniques are scarce. PURPOSE: To perform a comprehensive systematic review and meta-analysis of high-quality studies to evaluate the results of osteochondral autograft and allograft transplantation for the treatment of symptomatic cartilage defects of the knee. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 2. METHODS: A comprehensive search of the literature was conducted using various databases. Inclusion criteria were level 1 or 2 original studies, studies with patients reporting knee cartilage injuries and chondral defects, mean follow-up ≥2 years, and studies focusing on osteochondral transplant techniques. Exclusion criteria were studies with nonknee chondral defects, studies reporting clinical outcomes of osteochondral autograft or allograft combined with other procedures, animal studies, cadaveric studies, non-English language studies, case reports, and reviews or editorials. Primary outcomes included patient-reported outcomes and failure rates associated with both techniques, and factors such as lesion size, age, sex, and the number of plugs transplanted were assessed. Metaregression using a mixed-effects model was utilized for meta-analyses. RESULTS: The search resulted in 20 included studies with 364 cases of osteochondral autograft and 272 cases of osteochondral allograft. Mean postoperative survival was 88.2% in the osteochondral autograft cohort as compared with 87.2% in the osteochondral allograft cohort at 5.4 and 5.2 years, respectively (P = .6605). Patient-reported outcomes improved by an average of 65.1% and 81.1% after osteochondral autograft and allograft, respectively (P = .0001). However, meta-analysis revealed no significant difference in patient-reported outcome percentage change between osteochondral autograft and allograft (P = .97) and a coefficient of 0.033 (95% CI, -1.91 to 1.98). Meta-analysis of the relative risk of graft failure after osteochondral autograft versus allograft showed no significant differences (P = .66) and a coefficient of 0.114 (95% CI, -0.46 to 0.69). Furthermore, the regression did not find other predictors (mean age, percentage of female patients, lesion size, number of plugs/grafts used, and treatment location) that may have significantly affected patient-reported outcome percentage change or postoperative failure between osteochondral autograft versus allograft. CONCLUSION: Osteochondral autograft and allograft result in favorable patient-reported outcomes and graft survival rates at medium-term follow-up. While predictors for outcomes such as mean age, percentage of female patients, lesion size, number of plugs/grafts used, and treatment location did not affect the comparison of the 2 cohorts, proper patient selection for either procedure remains paramount to the success and potentially long-term viability of the graft.
