RESUMO
PURPOSE: To evaluate outcomes and complications of isolated medial patellofemoral ligament reconstruction (MPFLR), tibial tubercle osteotomy (TTO), and trochleoplasty for management of patellar instability. METHODS: A query of Scopus, PubMed, Google Scholar, Cochrane CENTRAL Register of Controlled Trials, and the Cochrane Database of Systematic Reviews was performed in accordance with 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Included studies reported clinical outcome data after isolated MPFLR, TTO, or trochleoplasty for patellar instability with a minimum 12-month follow-up. Meta-analysis and data aggregation was not performed. RESULTS: Thirty-six studies (5 trochleoplasty, 14 TTO, and 18 MPFLR) consisting of 1,389 patients (114 trochleoplasty, 374 TTO, and 1,001 MPFLR) were included. Risk of bias was assessed with the Methodological Index for Non-Randomized Studies score, which ranged from 11 to 12 in trochleoplasty, 10 to 18 in TTO, and 8 to 18 in MPFLR studies. Patient-reported outcome measures, including Lysholm score (trochleoplasty: 51.1-71 to 71-95; TTO: 57-63.3 to 84-98; MPFLR: 37.4-59.1 to 74-92.5), Kujala score (trochleoplasty: 56-71 to 78-92; TTO: 48.6-68 to 78-92; MPFLR: 53.3-60 to 81.5-92), visual analog scale for pain (trochleoplasty: 52-25; TTO: 54-76 to 14-27; MPFLR: 29 to 17, out of 100), and Tegner score (TTO: 3-4 to 3-4; MPFLR: 2.5-6 to 4.9-5), improved after all surgeries. Failure rates ranged from 0% to 33.3% after MPFLR, 0% to 30.8% after TTO, and 5.3% to 40% after trochleoplasty. Complication rates ranged from 0% to 14.7% after MPFLR, 1.6% to 58.3% after TTO, and 8% to 26.3% after trochleoplasty. CONCLUSIONS: Isolated MPFLR, TTO, or trochleoplasty may be effective treatment options for patellar stabilization. Although failure rates were highest after isolated trochleoplasty and complication rates were highest after TTO, these procedures are not interchangeable as each addresses a specific pathology. LEVEL OF EVIDENCE: Level IV, systematic review of Level II to IV studies.
RESUMO
PURPOSE: To compare time to achievement of clinically significant outcomes (CSOs) between patients undergoing primary and revision hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS). METHODS: Patients undergoing primary and revision HA for FAIS with complete 6-month, 1-year, and 2-year Hip Outcome Score - Activities of Daily Living (HOS-ADL) and Sport Subscale (HOS-SS) were identified. Revision patients were propensity matched 1:4 to primary HA patients, controlling for age, sex, and body mass index (BMI). Time to achievement of minimal clinically important difference (MCID) and substantial clinical benefit (SCB) were compared alongside cumulative CSO achievement at 6, 12, and 24 months. Hazard ratios (HR) for predictors of earlier CSO achievement were identified with multivariate Cox regressions. RESULTS: Fifty revision HA patients were propensity-matched to 200 primary HA patients of similar age, sex, and BMI. Primary HA patients demonstrated a greater prevalence of regular preoperative physical activity (87% vs. 59%, p<0.001). Primary HA patients showed significantly greater SCB achievement for HOS-ADL at 6, 12, and 24 months (p<0.001) and significantly greater SCB achievement for HOS-SS at 12 and 24 months (p≤0.001) compared to revision HA patients. Primary HA patients achieved SCB for HOS-ADL (p<0.001) and HOS-SS (p=0.015) quicker than revision HA patients. Predictors of earlier CSO achievement included preoperative PRO score (HR: 0.98-1.02, p≤0.007), lower BMI (HR: 0.97, p=0.038), presence of physical activity (HR: 1.51, p=0.038), and absence of revision status (HR: 0.52-0.56, p≤0.019). CONCLUSIONS: Primary HA patients showed a quicker time to SCB achievement for HOS-ADL and HOS-SS compared to revision HA patients. Preoperative PRO score, lower BMI, regular physical activity, and primary HA status predicted earlier CSO achievement. LEVEL OF EVIDENCE: Level III, retrospective comparative series.
RESUMO
PURPOSE: To assess patient-reported outcomes (PROs), clinically significant outcomes (CSOs), and survivorship following staged hip arthroscopy with labral repair, femoroplasty, and capsular plication followed by periacetabular osteotomy (PAO) for the management of femoroacetabular impingement syndrome (FAIS) and hip dysplasia (lateral center edge angle ≤25°). METHODS: A prospectively maintained database was queried to retrospectively identify patients who underwent staged primary hip arthroscopy and PAO between 1/2018-10/2021 and had a minimum 2-year follow-up. PROs collected included, Hip Outcome Score Activities of Daily Living/Sports Subscale (HOS-ADL/SS), international Hip Outcome Tool-12 item questionnaire (iHOT-12), and Visual Analog Scale for Pain (VAS Pain). CSO achievement for minimal clinical important difference (MCID) and patient acceptable symptom state (PASS) were determined through cohort specific thresholds. Rates of reoperation, including, revision hip arthroscopy and conversion to total hip arthroplasty (THA) were evaluated to determine short-term survivorship. RESULTS: Thirty-nine hips met criteria for inclusion, of which 35 hips had minimum 2-year follow up (89.7% compliance). Mean age was 25±9.1 years and 91.7% of patients were female. Respective pre- and postoperative radiographic outcomes were: Alpha angle 59.8±5.9 to 39.7±2.6°, Tönnis angle 14.6±5.6° to -1.0±2.9°, lateral center-edge angle 16.6±5.5° to 36.6±4.6°, and anterior center-edge angle 15.6±9.1° to 36.1±3.8°, with statistically significant differences pre- to postoperatively for all (P<0.001). Patients demonstrated significant improvement in all PROs pre- to postoperatively (P ≤0.004). MCID and PASS achievement rates for any PRO were 93.9% and 78.8%, respectively. There were no revision hip surgeries or conversion to THA at a mean 2.7±1.0-year follow-up. Four patients (11.1%) underwent hardware removal. One patient (2.8%) experienced a postoperative infection treated with incision and drainage. CONCLUSIONS: Staged hip arthroscopy and PAO for the management of hip dysplasia demonstrated improvement in PROs, high CSO achievement rates, and 100% survivorship at minimum 2-year follow-up.
RESUMO
PURPOSE: To perform a meta-analysis of randomized controlled trials (RCTs) to compare the outcomes of arthroscopic rotator cuff repair (ARCR) with and without acellular collagen matrix patch (ACMP) augmentation. METHODS: A literature search of 3 databases was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RCTs comparing ACMP augmentation and a control for ARCR were included. Clinical outcomes were compared using Revman, and a P value < .05 was considered to be statistically significant. RESULTS: Five RCTs with 307 patients were included. Overall, 11% of patients treated with ACMP augmentation and 34% of patients in the control group had a re-tear (P = .0006). The mean Constant score was 90.1 with ACMP augmentation, and 87.3 in controls (P = .02). Additionally, there was a significant higher American Shoulder and Elbow Surgeons score with ACMP augmentation (87.7 vs 82.1, P = .01). CONCLUSIONS: The RCTs in the literature support the use of ACMP augment as a modality to reduce re-tear rates and improve outcomes after ARCR. LEVEL OF EVIDENCE: Level II, Meta-Analysis of Level II Studies meta-analysis of Level II studies.

PURPOSE: To evaluate patient-reported outcomes (PROs) and survivorship at mid-term follow-up after hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS) in patients with and without preoperative lower back pain (LBP). METHODS: Patients with self-endorsed preoperative LBP who underwent HA for FAIS with mid-term follow-up were identified and propensity matched 1:1 to patients without back pain by age, sex, and body mass index (BMI). PROs collected preoperatively and at postoperative years 1, 2, and 5 included Hip Outcome Score-Activities of Daily Living (HOS-ADL) and Hip Outcome Score-Sports Subscale (HOS-SS), 12-item International Hip Outcome Tool (iHOT-12), modified Harris Hip Score (mHHS), and Visual Analog Scale (VAS) for Pain. Achievement of minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) were compared. Survivorship was compared with Kaplan-Meier analysis. RESULTS: In total, 119 patients with LBP were matched to 119 patients without LBP. Group demographic factors were as follows: age (37.4 ± 11.9 vs 37.6 ± 12.6 years, P = .880), sex (64.4% vs 67.7% female, P = .796), and BMI (25.3 ± 5.1 vs 25.3 ± 5.4, P = .930). Average follow-up duration was 6.0 ± 1.9 years. LBP patients showed similar preoperative PROs, yet lower 1-year scores for all PROs (P ≤ .044). At final follow-up, similar PROs were shown between groups (P ≥ .196). LBP and non-LBP patients had similar MCID achievement for HOS-ADL (59.3% vs 63.1%, P = .640), HOS-SS (73.9% vs 70.8%, P = .710), mHHS (66.7% vs 73.4%, P = .544), iHOT-12 (85.1% vs 79.4%, P = .500), and VAS Pain (75.6% vs 69.9%, P = .490). Groups also had similar PASS achievement for HOS-ADL (63.5% vs 61.3%, P = .777), HOS-SS (57.0% vs 62.5%, P = .461), mHHS (81.9% vs 79.1%, P = .692), iHOT-12 (54.6% vs 61.2%, P = .570), and VAS Pain (51.0% vs 55.4%, P = .570). Additionally, achievement of MCID ≥ 1 PRO (P ≥ .490) and PASS ≥ 1 PRO (P ≥ .370) was similar across groups. Conversion to total hip arthroplasty occurred in 3.4% of hips with LBP and 0.8% of hips without LBP (P = .370). Back pain patients demonstrated inferior time-dependent survivorship compared with patients without back pain on Kaplan-Meier survival analysis (P = .023). CONCLUSIONS: Patients undergoing primary hip arthroscopy for FAIS with LBP achieve comparable PROs and clinically significant outcomes to patients without back pain at mid-term, despite lower 1-year PRO scores. LBP patients show inferior reoperation-free time-dependent survivorship compared with those without LBP. LEVEL OF EVIDENCE: Level III, retrospective comparative case series.
RESUMO
PURPOSE: To analyze the quality and readability of information regarding shoulder stabilization surgery available using an online AI software (ChatGPT), using standardized scoring systems, as well as to report on the given answers by the AI. METHODS: An open AI model (ChatGPT) was used to answer 23 commonly asked questions from patients on shoulder stabilization surgery. These answers were evaluated for medical accuracy, quality, and readability using The JAMA Benchmark criteria, DISCERN score, Flesch-Kincaid Reading Ease Score (FRES) & Grade Level (FKGL). RESULTS: The JAMA Benchmark criteria score was 0, which is the lowest score, indicating no reliable resources cited. The DISCERN score was 60, which is considered a good score. The areas that open AI model did not achieve full marks were also related to the lack of available source material used to compile the answers, and finally some shortcomings with information not fully supported by the literature. The FRES was 26.2, and the FKGL was considered to be that of a college graduate. CONCLUSIONS: There was generally high quality in the answers given on questions relating to shoulder stabilization surgery, but there was a high reading level required to comprehend the information presented. However, it is unclear where the answers came from with no source material cited. It is important to note that the ChatGPT software repeatedly references the need to discuss these questions with an orthopaedic surgeon and the importance of shared discussion making, as well as compliance with surgeon treatment recommendations. CLINICAL RELEVANCE: As shoulder instability is an injury that predominantly affects younger individuals who may use the Internet for information, this study shows what information patients may be getting online.

PURPOSE: To systematically review the current evidence in the literature to compare return to play following arthroscopic Bankart repair versus open Latarjet procedure for the treatment of anterior shoulder instability. METHODS: A literature search was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Comparative studies reporting return to play following arthroscopic Bankart repair versus open Latarjet procedure were included. Return to play was compared, with all statistical analysis performed using Review Manager, Version 5.3. RESULTS: Nine studies with 1,242 patients (mean age: 15-30 years) were included. The rate of return to play was 61% to 94.1% among those undergoing arthroscopic Bankart repair and 72% to 96.8% in those undergoing an open Latarjet procedure. Two studies (Bessiere et al. and Zimmerman et al.) found a significant difference in favor of the Latarjet procedure (P < .05 for both, I2 = 37%). The rate of return to play at preinjury level was 9% to 83.8% among those undergoing arthroscopic Bankart repair and 19.4% to 80.6% in those undergoing an open Latarjet procedure, with no study finding a significant difference (P > .05 for all, I2 = 0%). The mean time of return to play was 5.4 to 7.3 months among those undergoing arthroscopic Bankart repair and 5.5 to 6.2 months in those undergoing an open Latarjet procedure, with no study finding a significant difference (P > .05 for all, I2 = 39%). CONCLUSIONS: Overall, the majority of studies showed no significant difference in rates of return to play or timing following arthroscopic Bankart repair or open Latarjet procedure. Furthermore, no study has found a significant difference in rate of return to play at pre-injury level, or rate of return to play among collision athletes. LEVEL OF EVIDENCE: Level III, systematic review of Level I-III studies.

Platelet-rich plasma (PRP) is an autologous blood product containing a high concentration of platelets, growth factors, and cytokines, which basic science studies have shown may improve tendinopathy. However, there is controversy over its clinical efficacy with randomized controlled trials and subsequent meta-analysis finding mixed results when treating shoulder rotator cuff tendinopathy. The effect of leukocyte concentration on PRP has been shown to be paramount, with different concentrations being favored for different pathologies. In those with tendinopathy, it is unclear whether leukocyte-rich or leukocyte-poor PRP is superior. Recent research shows that PRP injections produced a significant improvement in most patients with rotator cuff tendinopathy. However, improvement in symptoms and functional outcomes is worse in patients who have a partial-thickness rotator cuff tear compared with isolated tendinopathy without a partial tear. PRP may be more advantageous than corticosteroids. Both function as anti-inflammatories, but PRP may be potentially anabolic, whereas as corticosteroids have a catabolic effect on tendons, which may reduce repairability if patients proceed with surgery. Additionally, there are higher infection rates if patients ultimately go on to surgery within 3 months after corticosteroid injections. Ultimately, we must refine the indications for best use for PRP shoulder injections and determine the 5 R's: right patient, right drug, right dose, right route, and right time. Finally, we must remember that patients can first try conservative management, including physical therapy.

Effective analgesia is essential after anterior cruciate ligament (ACL) reconstruction to control pain while minimizing opioid consumption and allowing early rehabilitation. Orthopaedic surgeons write the third-largest number of opioid prescriptions, which are responsible for 1/10th of all opioid prescriptions, and one-third of patients with ACL injury use opioids preoperatively, a risk factor for postoperative abuse. Pain management after ACL reconstruction using variety of analgesic regimens including various permutations of nerve blocks, nerve block adjuncts, intra-articular injections, intravenous and oral medications, cryotherapy, compression stockings, and transcutaneous electrical nerve stimulation units, based on multidisciplinary collaboration between surgeons and anesthesiologists, can minimize opioid consumption. A recent meta-analysis shows that combined femoral-sciatic nerve block may be a top-ranked analgesic technique. Femoral and adductor canal nerve blocks are also effective alternatives and most common. Femoral and femoral sciatic nerve blocks may risk quadriceps strength deficits, whereas an advantage of adductor canal nerve is that the saphenous nerve is purely sensory. We recommend longer-acting nerve blockade (72 hours) using continuous anesthetic delivery via a pump/catheter with ropivacaine or the use of a slow-release preparation such as bupivacaine liposome injectable suspension.

BACKGROUND: Orthopaedic surgeons prescribe more opioid narcotics than any other surgical specialty. Proximal humerus fractures (PHF) often occur in the high-risk elderly population. The opioid epidemic has led to public policy aimed at reductions in opioid prescription. This study aimed to evaluate the impact that new legislation has had on opioid prescription patterns in patients who sustained proximal humerus fractures. METHODS: A retrospective review of all patients who sustained PHF at a single academic institution from 1/1/2015-12/31/2019 was performed. A total of 762 proximal humerus fractures were identified and final analysis included 383 patients. Collected data included basic demographics and opioid prescriptions obtained through review of the electronic medical record. The North Carolina Strengthen Opioid Misuse Prevention act legislation that went into effect on July 1, 2017. RESULTS: There was no difference in the number of pre- or postoperative opioid prescriptions provided with the new legislation. Our data showed a significant reduction in MeQs prescribed preoperatively pre-STOP act (188.1 MeQs) and post-STOP act (99.4 MeQs). There was also a significant difference in the amount of postoperative narcotics prescribed in the pre-STOP (972.6 MeQs) and post-STOP act (508.6 MeQs) groups (p < 0.01). CONCLUSIONS: With the enactment of the STOP act in North Carolina, we have seen a significant reduction in the amount of narcotic prescribed after sustaining a proximal humerus fracture preoperatively and postoperatively. This data demonstrates the impact that implementation of state-wide regulatory changes in opioid prescribing policy has had for a common orthopedic condition.

PURPOSE: To assess the national trends in arthroscopic and open rotator cuff repair surgery and the associated demographics, complications, and risk factors specific to each procedure. METHODS: A retrospective cohort study was performed using the National Surgical Quality Improvement Program (NSQIP) dataset between the years 2007 and 2018. Patients were identified using Common Procedural Terminology codes for open and arthroscopic rotator cuff repair. Variables collected including basic demographics, procedural, and outcome specific variables as available through the NSQIP repository. Appropriate statistical measures were used to compare the groups, with the χ2 test used for categorical variables and t test for continuous variables. RESULTS: The arthroscopic cohort comprised 39,013 patients; the open group consisted of 8,664. Reported arthroscopic and open cases increased significantly between 2007 and 2018 from 135 to 7,269 and 65 to 1,168, respectively. Average operative time for arthroscopic procedure was 89 minutes and 76 minutes for open. The open group consisted of a slightly greater percentage of smokers, 18.3% versus 15.2%, and patients with diabetes, 18.2% versus 15.9%, both of which were statistically significant (P < .001). Open cases had an odds ratio of 3.05 for superficial infections and 7.40 for deep infections, both of which were statistically significant (P < .001). The open cohort also had an odds ratio of 1.71 for unplanned readmissions when compared with the arthroscopic cohort, which was also statistically significant (P < .001). CONCLUSIONS: According to the NSQIP database, the increase in arthroscopic procedures is significantly outpacing the increase in open procedures during this study period, which matches the trends seen in previous studies. Patients with diabetes and who smoke also represent a greater risk group for postoperative complications when undergoing open surgery. These findings suggest that perhaps the decision to pursue one technique over the other may be influenced both by provider preference and patient-related factors. LEVEL OF EVIDENCE: III, retrospective comparative trial.

Orthoregeneration is defined as a solution for orthopaedic conditions that harnesses the benefits of biology to improve healing, reduce pain, improve function, and optimally, provide an environment for tissue regeneration. Options include drugs, surgical intervention, scaffolds, biologics as a product of cells, and physical and electromagnetic stimuli. The goal of regenerative medicine is to enhance the healing of tissue after musculoskeletal injuries as both isolated treatment and adjunct to surgical management, using novel therapies to improve recovery and outcomes. Various orthopaedic biologics (orthobiologics) have been investigated for the treatment of pathology involving the foot and ankle (including acute traumatic injuries and fractures, tumor, infection, osteochondral lesions, arthritis, and tendinopathy) and procedures, including osteotomy or fusion. Promising and established treatment modalities include 1) bone-based therapies (such as cancellous or cortical autograft from the iliac crest, proximal tibia, and/or calcaneus, fresh-frozen or freeze-dried cortical or cancellous allograft, including demineralized bone matrix putty or powder combined with growth factors, and synthetic bone graft substitutes, such as calcium sulfate, calcium phosphate, tricalcium phosphate, bioactive glasses (often in combination with bone marrow aspirate), and polymers; proteins such as bone morphogenic proteins; and platelet-derived growth factors; 2) cartilage-based therapies such as debridement, bone marrow stimulation (such as microfracture or drilling), scaffold-based techniques (such as autologous chondrocyte implantation [ACI] and matrix-induced ACI, autologous matrix-induced chondrogenesis, matrix-associated stem cell transplantation, particulated juvenile cartilage allograft transplantation, and minced local cartilage cells mixed with fibrin and platelet rich plasma [PRP]); and 3) blood, cell-based, and injectable therapies such as PRP, platelet-poor plasma biomatrix loaded with mesenchymal stromal cells, concentrated bone marrow aspirate, hyaluronic acid, and stem or stromal cell therapy, including mesenchymal stem cell allografts, and adipose tissue-derived stem cells, and micronized adipose tissue injections.

The optimal management of chronic Achilles tendon injuries continues to be debated. The tension-length relationship and intrinsic viscoelasticity of the native tendon that allows efficient propulsion during ambulation are difficult to restore once the tendon has been injured. Missed or misdiagnosed injuries or failure of surgical or nonsurgical management of acute Achilles tendon ruptures can lead to the tendon healing in an elongated position or lack of healing altogether. This condition results in persistent weakness, pain, and functional debilitation for the patient. Understanding the tendon and muscle properties will inform the choice of treatment. Nonsurgical treatment options are primarily bracing treatment and physical therapy. Surgical treatment options involve direct repair, reconstruction with local tissue, allograft or autograft, and tendon transfer. Various options and techniques for reconstruction are described to assist in optimizing management of this challenging clinical problem.

Proximal humerus fractures (PHF) are common in elderly and osteoporotic patients, and these fractures are often described using the Neer classification. As reverse shoulder arthroplasty (RSA) for PHF becomes more common, it is helpful to identify the utility of Neer classification in predicting postoperative outcomes for patients undergoing RSA. The medical records of patients undergoing primary RSA for PHF at a single academic institution from 2013-2019 were identified using medical billing codes. A multivariable logistic regression analysis identified independent factors associated with all cause 90-day readmissions, reoperation, and length of stay (LOS) greater than three days. Fifty-five patients (average age of 72.3 ± 8.6 years) were included. No statistically significant differences among two-, three-, and four-part fractures with regard to LOS, discharge location, 90-day readmission, revision surgery, postoperative dislocation, or deep infection were detected. These findings suggest that Neer classification for PHF is not predictive of short-term complications after RSA. (Journal of Surgical Orthopaedic Advances 31(2):104-108, 2022).

BACKGROUND: It has been theorized that tibialis posterior tendon dysfunction (TPTD) is a degenerative process unrelated to inflammation. The purpose of this study was to determine if inflammatory cytokines, matrix metalloproteases (MMPs), and glutamate were elevated in diseased tibialis posterior tendons (TPTs). METHODS: Matched diseased TPT, TPT insertion, and flexor digitorum longus (FDL) samples were collected from 21 patients. The samples were individually incubated in media, which was analyzed for inflammatory cytokines, MMPs, and glutamate. Histology and statistical analyses were performed. RESULTS: Diseased TPT and TPT insertion were significantly elevated compared to transferred FDL in eight inflammatory markers (p < 0.005). Only the diseased TPT was significantly elevated compared to the transferred FDL tendons for glutamate (p < 0.01). Histologic grading correlated with inflammatory cytokine levels. CONCLUSION: Diseased TPT and TPT insertion demonstrated significantly elevated levels of inflammatory markers compared to the transferred tendons used as controls, suggesting a role for inflammation in the disease process. The amount of inflammation correlated with increased tendon degradation. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Ankle fractures are common orthopedic injuries with complication rates fixation of up to 40%. Limited evidence exists in the literature regarding complications in the elderly population, and moreover, these studies frequently define elderly arbitrarily at 60-65 years old. The purpose of the present study was to utilize a large, validated database to evaluate whether there is an inflection point of age when postoperative complications after an ankle fracture significantly increase. METHODS: A retrospective review of all patients in the American College of Surgeons National Surgical Quality Improvement Program database who underwent fixation of an ankle fracture between 2012 and 2018 was performed. Patients were identified within the database using the Current Procedural Terminology codes. Appropriate statistical analysis was performed with p value less than 0.05 considered statistically significant. RESULTS: A total of 27,633 fractures were including and comprised of 221 posterior malleolar, 1567 medial malleolar, 8495 lateral malleolar, 10,175 bimalleolar, and 7175 trimalleolar. A total of 1545 complications were encountered (5.6%). There was a statistically significant association between increasing age and complications (OR = 1.03; p < 0.001). Further analysis shows the largest spike in complications within the age 78 + bracket. There were no overall interaction effects between age and fracture subtype (p = 0.223). CONCLUSION: ORIF of ankle fractures is a common orthopedic procedure performed on patients of all ages, with complications ranging in severity. In order to best counsel patients on their individual postoperative risks, large datasets are often necessary to prognosticate. This study found that postoperative complications increase with advanced age. The incidence of complications did not spike for patients around the age of 65, but rather followed an incremental linear pattern with the largest increase in odds ratio occurring at age 78 and above. Complication rate was not associated with specific fracture type based off of ICD codes.

BACKGROUND: In young athletes, an association exists between an increased posterior tibial slope (PTS) and the risk of primary anterior cruciate ligament (ACL) injury, ACL graft rupture, contralateral ACL injury, and inferior patient reported outcomes after ACL reconstruction. In spite of this, there is no consensus on the optimal measurement method for PTS in pediatric patients. The purpose of this study was to evaluate the reliability of previously described radiographic PTS measurement techniques. METHODS: A retrospective review was performed on 130 patients with uninjured knees between the ages of 6 and 18 years. The medial PTS was measured on lateral knee radiographs by four blinded reviewers using three previously described methods: the anterior tibial cortex (ATC), posterior tibial cortex (PTC), and the proximal tibia anatomic axis (PTAA). The radiographs were graded by each reviewer twice, performed 2 weeks apart. The intrarater and inter-rater reliability were assessed using the intraclass correlation coefficient (ICC). Subgroup analyses were then performed stratifying by patient age and sex. RESULTS: The mean PTS were significantly different based on measurement method: 12.5 degrees [confidence interval (CI): 12.2-12.9 degrees] for ATC, 7.6 degrees (CI: 7.3-7.9 degrees) for PTC, and 9.3 degrees (CI: 9.0-9.6 degrees) for PTAA (P<0.0001). Measures of intrarater reliability was excellent among all reviewers across all 3 methods of measuring the PTS with a mean ICC of 0.87 (range: 0.82 to 0.92) for ATC, 0.83 (range: 0.82 to 0.87) for PTC, and 0.88 (range: 0.79 to 0.92) for PTAA. The inter-rater reliability was good with a mean ICC of 0.69 (range: 0.62 to 0.83) for the ATC, 0.63 (range: 0.52 to 0.83) for the PTC, and 0.62 (range: 0.37 to 0.84) for the PTAA. Using PTAA referencing, the PTS was greater for older patients: 9.9 degrees (CI: 7.7-9.4 degrees) vs 8.5 degrees (CI: 9.2-10.7 degrees) (P=0.0157) and unaffected by sex: 9.5 degrees (CI: 8.8-10.1 degrees) for females and 9.0 degrees (CI: 8.0-10.0) for males (P=0.4199). There were no major differences in intrarater or inter-rater reliability based on age or sex. CONCLUSIONS: While the absolute PTS value varies by measurement technique, all methods demonstrated an intrarater reliability of 0.83 to 0.88 and inter-rater reliability of 0.61 to 0.69. However, this study highlights the need to identify PTS metrics in children with increased inter-rater reliability. LEVEL OF EVIDENCE: IV, Case series.

BACKGROUND: Shoulder periprosthetic joint infection (PJI) is a significant complication after arthroplasty with high morbidity. An evidence-based algorithm for the treatment of shoulder PJI is lacking in current practice. The purpose of this systematic review and meta-analysis was to understand and compare the role of single- and 2-stage shoulder arthroplasty revision for PJI. METHODS: A comprehensive literature review was performed to identify all studies related to shoulder arthroplasty for PJI in PubMed, Scopus, and EMBASE. Inclusion criteria for this systematic review were studies that reported on single- or 2-stage revision, with infection eradication and a minimum follow-up of 12 months and a minimum of 5 patients for analysis. A random-effects meta-analysis was performed, and heterogeneity was assessed with Cochrane Q and I2. RESULTS: A total of 13 studies reporting on single-stage revision and 30 studies reporting on 2-stage revision were included in final analysis. The majority of positive cultures from single-stage revision for PJI resulted in Cutibacterium acnes with 113 of 232 (48.7%) reported cases compared with 190 of 566 (33.7%) reported cases for 2-stage revision. However, there was a lower percentage of methicillin-resistant Staphylococcus aureus positive cultures, with 2.5% for single-stage compared with 9.7% for 2-stage revision. The overall pooled random-effect reinfection incidence was 0.05 (95% confidence interval: 0.02-0.08), with moderate heterogeneity (I2 = 34%, P = .02). The reinfection rate was 6.3% for single-stage and 10.1% for 2-stage revision, but this was not significant (Q = 0.9 and P = .40). CONCLUSION: Based on a systematic review with meta-analysis, single-stage revision for shoulder PJI is an effective treatment. Indeed, our analysis showed single-stage to be more effective than 2-stage, but this is likely confounded by a treatment bias given the higher propensity of virulent and drug-resistant bacteria treated with 2-stage in the published literature. This implies that shoulder surgeons treating PJI can be reassured of a low recurrence rate (6.3%) when using single-stage treatment for C acnes or other sensitive, low-virulence organisms.
