RESUMEN
BACKGROUND: Approximately 20% to 50% of patients develop persistent pain after traumatic orthopaedic injuries. Psychosocial factors are an important predictor of persistent pain; however, there are no evidence-based, mind-body interventions to prevent persistent pain for this patient population. QUESTIONS/PURPOSES: (1) Does the Toolkit for Optimal Recovery after Injury (TOR) achieve a priori feasibility benchmarks in a multisite randomized control trial (RCT)? (2) Does TOR demonstrate a preliminary effect in improving pain, as well as physical and emotional function? METHODS: This pilot RCT of TOR versus a minimally enhanced usual care comparison group (MEUC) was conducted among 195 adults with an acute orthopaedic traumatic injury at risk for persistent pain at four geographically diverse Level 1 trauma centers between October 2021 to August 2023. Fifty percent (97 of 195) of participants were randomized to TOR (mean age 43 ± 17 years; 67% [65 of 97] women) and 50% (98) to MEUC (mean age 45 ± 16 years; 67% [66 of 98] women). In TOR, 24% (23 of 97) of patients were lost to follow-up, whereas in the MEUC, 17% (17 of 98) were lost. At 4 weeks, 78% (76 of 97) of patients in TOR and 95% (93 of 98) in the MEUC completed the assessments; by 12 weeks, 76% (74 of 97) of patients in TOR and 83% (81 of 98) in the MEUC completed the assessments (all participants were still included in the analysis consistent with an intention-to-treat approach). The TOR has four weekly video-administered sessions that teach pain coping skills. The MEUC is an educational pamphlet. Both were delivered in addition to usual care. Primary outcomes were feasibility of recruitment (the percentage of patients who met study criteria and enrolled) and data collection, appropriateness of treatment (the percent of participants in TOR who score above the midpoint on the Credibility and Expectancy Scale), acceptability (the percentage of patients in TOR who attend at least three of four sessions), and treatment satisfaction (the percent of participants in TOR who score above the midpoint on the Client Satisfaction Scale). Secondary outcomes included additional feasibility (including collecting data on narcotics and rescue medications and adverse events), fidelity (whether the intervention was delivered as planned) and acceptability metrics (patients and staff), pain (numeric rating scale), physical function (Short Musculoskeletal Function Assessment questionnaire [SMFA], PROMIS), emotional function (PTSD [PTSD Checklist], depression [Center for Epidemiologic Study of Depression]), and intervention targets (pain catastrophizing, pain anxiety, coping, and mindfulness). Assessments occurred at baseline, 4 and 12 weeks. RESULTS: Several outcomes exceeded a priori benchmarks: feasibility of recruitment (89% [210 of 235] of eligible participants consented), appropriateness (TOR: 73% [66 of 90] scored > midpoint on the Credibility and Expectancy Scale), data collection (79% [154 of 195] completed all surveys), satisfaction (TOR: 99% [75 of 76] > midpoint on the Client Satisfaction Scale), and acceptability (TOR: 73% [71 of 97] attended all four sessions). Participation in TOR, compared with the MEUC, was associated with improvement from baseline to postintervention and from baseline to follow-up in physical function (SMFA, baseline to post: -7 [95% CI -11 to -4]; p < 0.001; baseline to follow-up: -6 [95% CI -11 to -1]; p = 0.02), PROMIS (PROMIS-PF, baseline to follow-up: 2 [95% CI 0 to 4]; p = 0.045), pain at rest (baseline to post: -1.2 [95% CI -1.7 to -0.6]; p < 0.001; baseline to follow-up: -1 [95% CI -1.7 to -0.3]; p = 0.003), activity (baseline to post: -0.7 [95% CI -1.3 to -0.1]; p = 0.03; baseline to follow-up: -0.8 [95% CI -1.6 to -0.1]; p = 0.04), depressive symptoms (baseline to post: -6 [95% CI -9 to -3]; p < 0.001; baseline to follow-up: -5 [95% CI -9 to -2]; p < 0.002), and posttraumatic symptoms (baseline to post: -4 [95% CI -7 to 0]; p = 0.03; baseline to follow-up: -5 [95% CI -9 to -1]; p = 0.01). Improvements were generally clinically important and sustained or continued through the 3 months of follow-up (that is, above the minimum clinically important different [MCID] of 7 for the SMFA, the MCID of 3.6 for PROMIS, the MCID of 2 for pain at rest and pain during activity, the MCID of more than 10% change in depressive symptoms, and the MCID of 10 for posttraumatic symptoms). There were treatment-dependent improvements in pain catastrophizing, pain anxiety, coping, and mindfulness. CONCLUSION: TOR was feasible and potentially efficacious in preventing persistent pain among patients with an acute orthopaedic traumatic injury. Using TOR in clinical practice may prevent persistent pain after orthopaedic traumatic injury. LEVEL OF EVIDENCE: Level I, therapeutic study.
RESUMEN
BACKGROUND: Multiple patient-reported outcome measures (PROMs) have been used to assess shoulder function, but it is unknown which are the most effective. PURPOSE/HYPOTHESIS: The purpose of this study was to report the multiple PROMs used after rotator cuff repair (RCR) and to compare the responsiveness between them. It was hypothesized that the Western Ontario Rotator Cuff PROM would be the most responsive and commonly used in patients undergoing RCR. STUDY DESIGN: Meta-analysis; Level of evidence, 4. METHODS: A systematic review was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and PRISMA-Searching extension guidelines via PubMed/MEDLINE, Embase (Elsevier), and Web of Science (Clarivate). Patient and study characteristics were extracted. From the studies that met inclusion criteria for responsiveness analysis (≥2 PROMs reported, 1-year minimum follow-up, and pre- and postoperative PROM means and standard deviations reported), the authors compared the responsiveness between PROM instruments using effect size and relative efficiency (RE) if a PROM could be compared with another in ≥10 articles. RESULTS: A total of 252 studies met inclusion criteria (32,072 patients; mean age, 59.6 years; mean body mass index, 28.7; mean follow-up time, 27.8 months). Range of motion was reported in 131 (52%) studies and imaging findings were reported in 123 (49%) studies. There were 67 PROM instruments identified; the most commonly used were the American Shoulder and Elbow Surgeon (ASES) (n = 183; 73%), Visual Analog Scale (VAS) (n = 163; 65%), and Constant (n = 118; 47%) scores. The 3 PROMs with the highest effect sizes were the University of California, Los Angeles (UCLA) (2.51), Western Ontario Rotator Cuff (2.42), and ASES (2.00) scores. Overall, UCLA and ASES scores were the most responsive PROMs. The ASES PROM was more responsive than the VAS (RE, 1.70), Constant (RE, 2.76), Simple Shoulder Test (RE, 1.67), and Single Assessment Numeric Evaluation (RE, 2.14) scores. The UCLA PROM was more responsive than the ASES (RE, 1.03), VAS (RE, 3.66), Constant (RE, 1.72), and Simple Shoulder Test (RE, 1.66) scores. CONCLUSION: ASES and UCLA scores were the most responsive PROMs after RCR. The authors recommend widespread adoption of ASES and UCLA scores for clinical and research standardization; however, the UCLA PROM requires in-person range of motion and strength testing, which is a practical limitation and barrier to long-term follow-up.
RESUMEN
OBJECTIVE: Compare the incidence of total knee arthroplasty (TKA) within the first 5 years after knee OA diagnoses between matched groups of individuals with or without comorbid diagnoses of obesity and/or depression. We hypothesized that the greatest incidence of TKA within 5 years of OA diagnosis would be in the cohort of individuals with combined obesity and depression. METHODS: The PearlDiver Mariner Ortho157 database was used to identify four cohorts of individuals with knee OA based on diagnosis codes that were matched by age, sex, and Charlson Comorbidity Index: a group without diagnoses associated with depression or obesity (Control), those with obesity but not depression (Obesity), those with depression but not obesity (Depression), and those with diagnoses of both obesity and depression (Depression+Obesity). The incidence of subsequent TKA within the first 5 years after the index OA diagnosis were compared between the four matched cohorts. RESULTS: Each cohort was comprised of 274,403 unique individuals (180,563 females, 93,840 males; age=55±7 y). The incidence of TKA was greatest for the Depression+Obesity group (11.9%) when compared to the Control group (8.3%, p<0.0001, RR=1.43 [95%CI:1.41,1.45]), the Obesity group (10.2%, p<0.0001, RR=1.13 [95%CI:1.11,1.14], p<0.0001) or Depression (7.8%, p<0.0001, RR=1.53 [95%CI:1.50,1.55], p<0.0001). CONCLUSION: The incidence of subsequent TKA was greatest for those with the combination of obesity and depression when compared to the Control group and those with individual diagnosis of obesity or depression.
RESUMEN
PURPOSE: To determine whether the utilization of psychological treatments changes after arthroscopic rotator cuff repair (RCR) for patients with preoperative depression and/or anxiety. METHODS: The Truven Healthcare Marketscan database was used to identify patients who underwent arthroscopic RCR between January 2009 and December 2016. We included all patients with diagnosis codes associated with either depression or anxiety before RCR. Patients were excluded if they did not have complete insurance coverage for 1 year before or after surgery, or if they had arthroscopic RCR in the year before the index surgical procedure. We compared the proportion of patients with preoperative depression or anxiety who filled a prescription and had psychotherapy procedural codes in the year before and the year after arthroscopic RCR. RESULTS: A total of 170,406 patients who underwent RCR were identified, of which depression and/or anxiety was found in 46,737 patients (43.7% male). Of the 46,737 patients, 19.6% filled a prescription for a depression/anxiety medication at least once in the year before surgery. Of this subset of patients, 41.5% did not fill a prescription for depression or anxiety medication after surgery, whereas 32.6% continued medication use but demonstrated a median 30-day reduction in the number of days' worth of medication. Similarly, 13.1% of patients were attending psychotherapy sessions preoperatively, but 76.6% of those patients either stopped or reduced the amount of psychotherapy sessions in the year following RCR. CONCLUSIONS: The number of prescriptions and psychotherapy sessions decreased in the year after RCR for patients with preoperative diagnoses of depression and/or anxiety. LEVEL OF EVIDENCE: Level IV, case series.

Introduction The progression to posttraumatic osteoarthritis (PTOA) after an anterior cruciate ligament (ACL) injury is likely multifactorial, involving biological, mechanical, and psychosocial factors. Following acute joint trauma, there appears to be a subset of patients that demonstrate a dysregulated inflammatory response. This pro-inflammatory phenotype, or "Inflamma-type," is characterized by an amplified pro-inflammatory response combined with a lack of attendant anti-inflammatory response and has been observed following both an ACL injury and an intra-articular fracture. The aims of this study were to: 1) compare magnetic resonance imaging (MRI)-measured effusion synovitis between those with vs. without a dysregulated inflammatory response, and 2) assess the correlations between effusion synovitis and synovial fluid concentrations of proinflammatory cytokines, degradative enzymes, and synovial fluid biomarkers of cartilage degradation. Methods A cluster analysis was previously performed with synovial fluid concentrations of biomarkers of inflammation and cartilage degradation from 35 patients with acute ACL injuries. Patients were then categorized into two groups: a pro-inflammatory phenotype ("Inflamma-type") and those with a more normal inflammatory response to injury (NORM). Effusion synovitis measured from each patient's preoperative clinical MRI scan was compared between the Inflamma-type and NORM groups using an independent, two-tailed t-test. In addition, Spearman's rho non-parametric correlations were calculated to evaluate the relationship between effusion synovitis and each of the synovial fluid concentrations of pro-inflammatory cytokines, degradative enzymes, and biomarkers of cartilage degradation and bony remodeling. Results Effusion synovitis was significantly greater for the Inflamma-type (10.9±3.8 mm) than the NORM group (7.4±4.4 mm, p=0.04, Cohen's d=0.82). Effusion synovitis significantly correlated with matrix metalloproteinase-3 (rho=0.63, p<0.001), matrix metalloproteinase-1 (rho=0.50, p=0.003), and sulfated glycosaminoglycan (rho=0.42, p=0.01). No other significant correlations were present. Conclusion Effusion synovitis was significantly greater for those that demonstrated a dysregulated inflammatory response after acute ACL injury than those with a more normal response to injury. Effusion synovitis was also found to significantly correlate with synovial fluid concentrations of degradative enzymes and a biomarker of early cartilage degradation. Future work is needed to determine if non-invasive methods, such as MRI or ultrasound, may accurately identify patients within this pro-inflammatory phenotype and whether this subset is more prone to more rapid PTOA changes after injury.
RESUMEN
BACKGROUND: The incidence of subsequent posttraumatic osteoarthritis (OA) diagnosis after surgery and the associated risk factors have been well reported after single-ligament anterior cruciate ligament (ACL) reconstruction; however, to date, the incidence of posttraumatic OA for those who have experienced multiligament knee injury (MLKI) has been reported only in relatively small, single-center studies. PURPOSE: To compare the incidence of OA diagnoses between patients with ACL injury versus patients with MLKI and to identify risk factors for OA diagnosis after MLKI. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: This study used the PearlDiver Mariner database, which contains insurance claims information on >151 million orthopaedic patients. We identified 2 cohorts for this study by using Current Procedural Terminology codes. The cohorts included patients between the ages of 16 and 60 who underwent either isolated ACL reconstruction (n = 114,282) or MLKI reconstruction (n = 3325) between July 1, 2010, and August 30, 2016. MLKI reconstruction was operationally defined as ACL reconstruction plus concurrent surgical treatment of ≥1 additional ligaments. Demographic factors, concomitant meniscal and cartilage procedures, and subsequent reoperation to restore motion were recorded, as was the incidence of knee OA diagnosis within 5 years of the index surgical procedure. OA incidence and demographic and surgical factors were compared (1) between ACL and MLKI groups and (2) between patients with MLKI either with or without OA diagnosis. RESULTS: A significantly greater proportion of patients with MLKI were diagnosed with knee OA within 5 years of surgery (MLKI = 299/3325 [9.0%] vs ACL = 6955/114,282 [6.1%]; P < .0001) (odds ratio [OR], 1.52; 95% CI, 1.35-1.72; P < .001). Factors associated with increased odds of OA diagnosis after MLKI included age ≥30 years (OR, 5.90), reoperation to restore motion (OR, 2.54), obesity (OR, 1.96), mood disorder diagnoses (OR, 1.85), partial meniscectomy (OR, 1.85), and tobacco use (OR, 1.72). Concomitant meniscal repair was protective against OA diagnosis (OR, 0.06). CONCLUSION: OA incidence was greater after MLKI reconstruction than after isolated ACL reconstruction. Potentially modifiable risk factors for OA after MLKI were identified and include obesity, tobacco use, depression, and the need for motion-restoring surgery.

Objective: Given overlapping pathophysiology, this study sought to assess the association between osteoarthritis (OA), functional impairment, and cognitive impairment in the aging population. Methods: The National Health and Nutrition Examination Survey was used to identify participants >60 years of age. We analyzed multivariable associations of grouped participants that underwent cognitive function testing using linear and logistic regression, adjusting for sex, age, race, and ethnicity. Results: Of 2776 identified participants representing a population of 50,242,917, 40% did not report OA or functional limitations; 21% had OA but not functional limitations; 15% did not have OA but had functional limitations; 17% had OA and related functional limitations; and 7% had OA and non-arthritic functional limitations. OA was not independently associated with cognitive impairment. Contrarily, functional limitations were associated with cognitive impairment regardless of OA diagnosis. Discussion: Cognitive impairment is not associated with OA, but rather functional limitations, potentially guiding future intervention.

Objective and design: The purpose of this study was to compare synovial concentrations of pro- and anti-inflammatory cytokines between multiple-ligament knee injured (MLKI) and anterior cruciate ligament (ACL)-injured patients. Subjects: 14 patients with MLKI and 10 patients with isolated ACL injury. Methods: Synovial fluid was aspirated from the operative knee at the time of surgery and the concentrations of pro- and anti-inflammatory markers in the synovial fluid were determined. Structures injured, the time between injury and surgery, and demographic factors were collected. Linear regressions were used to determine the association between injury pattern and synovial inflammatory markers when controlling for age, BMI, and time between injury and surgery. Results: When adjusting for group differences in age, BMI and the time between injury and surgery, no group differences were detected (interferon gamma (p = 0.11), interleukin-1beta (IL-1b, p = 0.35), IL-2 (p = 0.28), IL-4 (p = 0.64), IL-6 (p = 0.37), IL-8 (p = 0.54), IL-10 (p = 0.25), IL-12p70 (p = 0.81), IL-13 (p = 0.31), and tumor necrosis factor-alpha (p = 0.90)). Conclusion: Synovial fluid inflammatory markers did not differ between MLKI and isolated ACL injuries. MLKIs have a greater prevalence of postoperative arthrofibrosis when compared to isolated ACL injuries; however, this may be due in part to factors other than the inflammatory status of the joint.
RESUMEN
BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) results in persistent altered knee biomechanics, but contributing factors such as pain or patient function, leading to the altered loading, are unknown. HYPOTHESIS: Individuals with worse self-reported pain after ACLR would have poorer biomechanics during running, and poor loading mechanics would be present in the ACLR limb compared with contralateral and control limbs. STUDY DESIGN: Cohort pilot study. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 20 patients after ACLR (age, 18.4 ± 2.7 years; height, 1.7 ± 0.1 m; mass, 84.2 ± 19.4 kg) completed visual analog scale and Knee Injury and Osteoarthritis Outcomes Score (KOOS) at 1 and 6 months postsurgery. At 6 months postsurgery, patients underwent biomechanical testing during running. A total of 20 control individuals also completed running biomechanical analyses. Associations between patient outcomes and biomechanics were conducted, and differences in running biomechanics between groups were analyzed. RESULTS: KOOS pain score 1 month after surgery was associated with peak ACLR knee abduction moment (R2 = 0.35;P = 0.01). At 6-months, KOOS sport score was related to peak abduction moment in the ACLR limb (R2 = 0.23; P = 0.05). For change scores, the improvement in pain scores related to ACLR limb peak knee abduction moment (R2 = 0.55; P = 0.001). The ACLR limb had lower knee excursion, extension moments, and ground-reaction forces compared with the uninvolved and control limb. The uninvolved limb also had higher ground-reaction forces compared with the ACLR limb and control limb. CONCLUSION: These results suggest that patient-reported outcomes 1 and 6 months after surgery are associated with running mechanics 6 months after ACLR. Further, the underloading present in the ACLR limb and overloading in the uninvolved limb indicates greater need for running rehabilitation after ACLR. CLINICAL RELEVANCE: Understanding pain and how it may be linked to movement dysfunction is important for improving long-term outcomes.
RESUMEN
OBJECTIVE AND DESIGN: The purpose of this study was to explore pathological processes during the first 4 weeks after anterior cruciate ligament reconstruction (ACLR). SUBJECTS: Sixteen ACL-injured patients (8 females/8 males, mean age = 19.1, mean BMI = 28.6). METHODS: Arthrocentesis was performed 1 and 4 weeks after ACLR. Proteins in the synovial fluid were identified using nanoLC-ESI-MS/MS. Differentially up- or down-regulated proteins were identified and quantified, and a pathway analysis was performed. All identified proteins were mapped into a protein-protein interaction (PPI) network, and networks of PPIs with a combined score > 0.9 were then visualized. RESULTS: Seven pathways were upregulated after ACLR: PI3K-AKT signaling pathway, extracellular matrix (ECM)-receptor interaction, focal adhesion, protein digestion and absorption, ameobiasis, and platelet activation. Network analyses identified 8 proteins that were differentially upregulated with strong PPI interactions (periostin and 7 collagen-related proteins). Increases in periostin moderately correlated with increases in a synovial fluid biomarker of type II cartilage degradation (ρ = 0.51, p = 0.06). CONCLUSION: Pro-inflammatory pathways and periostin were upregulated after ACLR. Periostin demonstrated strong network connections with markers of collagen breakdown, and future work is needed to determine whether periostin may offer a biomarker of early cartilage degradation after ACLR and/or play an active role in early post-traumatic osteoarthritis (PTOA) progression.

Anterior cruciate ligament (ACL) injury initiates a biochemical cascade thought to contribute to the onset and progression of posttraumatic osteoarthritis (PTOA). Interleukin-1ß (IL-1ß), IL-6, and C-telopeptide fragments of type II collagen (CTX-II) are implicated in joint inflammation and cartilage degradation following ACL injury; however, their association with pain is still being explored. The purpose of this study was to evaluate the associations between synovial fluid concentrations of IL-1ß, IL-6, and CTX-II with pain following ACL injury and reconstruction. We hypothesized that greater IL-1ß, IL-6, and CTX-II would correlate with greater Pain Visual Analogue Scale (VAS) scores. This was a secondary analysis of 23 patients (mean age = 18.4 years, BMI = 27.4, 13 females/10 males) with acute ACL tears who participated in a pilot randomized trial. Synovial fluid and VAS scores were collected on the day of initial presentation, at ACL reconstruction, and 1 and 4 weeks after surgery. Synovial fluid concentrations of IL-1ß, IL-6, and CTX-II were assessed using enzyme-linked immunoabsorbent assays, and repeated measures correlations were used to assess the relationships between pain and synovial IL-1ß, IL-6, or CTX-II after ACL injury and reconstruction. Pain was positively correlated with synovial fluid IL-6 concentrations (r = 0.52, p < 0.001); however, pain was inversely correlated with CTX-II (r = -0.39, p = 0.002). IL-1ß had no significant correlation with pain. Statement of clinical relevance: PTOA has been described as a "silent killer" and these results suggest that early PTOA may have pro-inflammatory pathways that are not primarily associated with pain but still lead to progressive cartilage loss.

OBJECTIVE: To identify the prevalence of mood disorder diagnoses in patients undergoing cartilage transplantation procedures and determine the relationship between mood disorders, opioid usage, and postoperative health care costs. DESIGN: Patients with current procedural terminology (CPT) codes for osteochondral autograft transplantation (OAT), osteochondral allograft transplantation (OCA), and autologous chondrocyte implantation (ACI) were identified in the Truven Health Marketscan database (January 2009-September 2014). Patients were grouped based on having a preoperative mood disorder diagnosis (preMDD). Preoperative opioids, postoperative opioids ≥90 days, and health care costs within the year postoperative were compared for those with and without mood disorders. Costs were analyzed, adjusting for preoperative cost, sex, age, and opioid usage, for those with and without mood disorders. RESULTS: A total of 3,682 patients were analyzed (ACI: 690, OAT: 1,294, OCA: 1,698). A quarter of patients had preMDD (ACI: 25.4%, OAT: 20.6%, OCA: 22.7%). Postoperative opioid use was more prevalent in preMDD patients (OAT: 37.1% vs. 24.1%, P < 0.001; OCA: 30.4% vs. 24.8%, P = 0.032; ACI: 33.7% vs. 26.2%, P = 0.070) (odds ratio [OR] ranged from 1.29 to 1.86). First-year postoperative log-transformed costs were significantly greater for preMDD patients (ACI: $7,733 vs. $5,689*, P = 0.012; OAT: $5,221 vs. $3,823*, P < 0.001; OCA: $6,973 vs. $3,992*, P < 0.001; *medians reported). The estimated adjusted first postoperative year cost increase for preMDD OCA patients was 41.7% (P < 0.001) and 28.0% for OAT patients (P = 0.034). There was no statistical difference for ACI patients (P = 0.654). CONCLUSION: Cartilage transplantation patients have a high prevalence of preoperative mood disorders. Opioid use and health care costs were significantly greater for patients with preoperative mood disorder diagnoses. LEVEL OF EVIDENCE: Level III, retrospective therapeutic study.

BACKGROUND: After anterior cruciate ligament (ACL) reconstruction, patient-reported outcomes are improved 10 years post-surgery; however, cytokine concentrations remain elevated years after surgery with over 80% of those with combined ACL and meniscus injuries having posttraumatic osteoarthritis (PTOA) within 10-15 years. The purpose of this multicenter, randomized, placebo-controlled trial is to assess whether a 6-month course of oral montelukast after ACL reconstruction reduces systemic markers of inflammation and biochemical and imaging biomarkers of cartilage degradation. METHODS: We will enroll 30 individuals undergoing primary ACL reconstruction to participate in this IRB-approved multicenter clinical trial. This trial will target those at greatest risk of a more rapid PTOA onset (age range 25-50 with concomitant meniscus injury). Patients will be randomly assigned to a group instructed to take 10 mg of montelukast daily for 6 months following ACL reconstruction or placebo. Patients will be assessed prior to surgery and 1, 6, and 12 months following surgery. To determine if montelukast alters systemic inflammation following surgery, we will compare systemic concentrations of prostaglandin E2, monocyte chemoattractant protein-1, and pro-inflammatory cytokines between groups. We will also compare degradative changes on magnetic resonance imaging (MRI) collected 1 and 12 months following surgery between groups with reductions in early biomarkers of cartilage degradation assessed with urinary biomarkers of type II collagen breakdown and bony remodeling. DISCUSSION: There is a complex interplay between the pro-inflammatory intra-articular environment, underlying bone remodeling, and progressive cartilage degradation. PTOA affects multiple tissues and appears to be more similar to rheumatoid arthritis than osteoarthritis with respect to inflammation. There is currently no treatment to delay or prevent PTOA after ACL injury. Since there is a larger and more persistent inflammatory response after ACL reconstruction than the initial insult of injury, treatment may need to be initiated after surgery, sustained over a period of time, and target multiple mechanisms in order to successfully alter the disease process. This study will assess whether a 6-month postoperative course of oral montelukast affects multiple PTOA mechanisms. Because montelukast administration can be safely sustained for long durations and offers a low-cost treatment option, should it be proven effective in the current trial, these results can be immediately incorporated into clinical practice.

BACKGROUND AND AIMS: The purpose of the review was to synthesize the current literature regarding tetracyclines in the treatment of osteoarthritis. METHODS: Using multiple databases, a systematic review was performed with customized search terms crafted to identify studies examining doxycycline or minocycline in the treatment of osteoarthritis. Results were classified into basic science mechanistic studies, in vivo animal studies, and human clinical trials. A total of 1446 potentially relevant studies were reviewed, and after exclusion criteria were applied, 23 investigations were included in the final analysis. RESULTS: From 12 basic science mechanistic studies, we report on three main mechanisms by which tetracyclines may exert benefit in osteoarthritis progression: matrix metalloproteinase inhibition, immunomodulation, and nitric oxide synthase inhibition. Seven animal studies showed generally encouraging results. Four articles reported human clinical studies, showing mixed results in the treatment of osteoarthritis, potentially related to the choice of patient population, primary outcomes, and timing of treatment. CONCLUSION: Tetracyclines have the potential to benefit osteoarthritis patients via multiple mechanisms.

CONTEXT: Postoperative quadriceps strength weakness after knee surgery is a persistent issue patients and health care providers encounter. OBJECTIVE: To investigate the effect of neuromuscular electrical stimulation (NMES) parameters on quadriceps strength after knee surgery. DATA SOURCES: CINAHL, MEDLINE, SPORTDiscus, and PubMed were systematically searched in December 2018. STUDY SELECTION: Studies were excluded if they did not assess quadriceps strength or if they failed to report the NMES parameters or quadriceps strength values. Additionally, studies that applied NMES to numerous muscle groups or simultaneously with other modalities/treatments were excluded. Study quality was assessed with the Physiotherapy Evidence Database (PEDro) scale for randomized controlled trials. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 1. DATA EXTRACTION: Treatment parameters for each NMES treatment was extracted for comparison. Quadriceps strength means and standard deviations were extracted and utilized to calculate Hedge g effect sizes with 95% CIs. RESULTS: Eight RCTs were included with an average Physiotherapy Evidence Database scale score of 5 ± 2. Hedge g effect sizes ranged from small (-0.37; 95% CI, -1.00 to 0.25) to large (1.13; 95% CI, 0.49 to 1.77). Based on the Strength of Recommendation Taxonomy Quality of Evidence table, the majority of the studies included were low quality RCTs categorized as level 2: limited quality patient-oriented evidence. CONCLUSION: Because of inconsistent evidence among studies, grade B evidence exists to support the use of NMES to aid in the recovery of quadriceps strength after knee surgery. Based on the parameters utilized by studies demonstrating optimal treatment effects, it is recommended to implement NMES treatment during the first 2 postoperative weeks at a frequency of ≥50 Hz, at maximum tolerable intensity, with a biphasic current, with large electrodes and a duty cycle ratio of 1:2 to 1:3 (2- to 3-second ramp).

Anterior cruciate ligament (ACL) injury leads to a sustained increase in synovial fluid concentrations of inflammatory cytokines and biomarkers of cartilage breakdown. While this has been documented post-injury, it remains unclear whether ACL reconstruction surgery contributes to the inflammatory process and/or cartilage breakdown. This study is a secondary analysis of 14 patients (nine males/five females, mean age = 9, mean BMI = 28) enrolled in an IRB-approved randomized clinical trial. Arthrocentesis was performed at initial presentation (mean = 6 days post-injury), immediately prior to surgery (mean = 23 days post-injury), 1-week post-surgery, and 1-month post-surgery. Enzyme-linked immunosorbant assay kits were used to determine concentrations of carboxy-terminal telopeptides of type II collagen (CTXII), interleukin-6 (IL-6), and IL-1ß in the synovial fluid. The log-transformed IL-1ß was not normally distributed; therefore, changes between time points were evaluated using a non-parametric Kruskal-Wallis one-way ANOVA. IL-1ß concentrations significantly increased from the day of surgery to the first postoperative time point (P ≤ .001) and significantly decreased at the 4-week postoperative visit (P = .03). IL-1ß concentrations at the 4-week postoperative visit remained significantly greater than both preoperative time points (P > .05). IL-6 concentrations at 1-week post-surgery were significantly higher than at initial presentation (P = .013), the day of surgery (P < .001), and 4 weeks after surgery (P = .002). CTX-II concentrations did not differ between the first three-time points (P > .99) but significantly increased at 4 weeks post-surgery (P < .01). ACL reconstruction appears to reinitiate an inflammatory response followed by an increase in markers for cartilage degradation. ACL reconstruction appears to initiate a second "inflammatory hit" resulting in increased chondral breakdown suggesting that post-operative chondroprotection may be needed.

PURPOSE: To determine if opioid use and health care costs in the year before and following hip arthroscopy for femoroacetabular impingement (FAI) differ between those with or without depression or anxiety. METHODS: Using the Truven Health Marketscan database, FAI patients who underwent hip arthroscopy between October 2010 and December 2015 were identified (Current Procedural Terminology codes 29914 [femoroplasty], 29915 [acetabuloplasty], and/or 29916 [labral repair]). Patients were excluded if they had incomplete coverage for 1 year either before or following surgery. The number of patients with 1 or more claims related to depression or anxiety during the year before surgery was quantified (International Statistical Classification Diseases and Related Health-9 codes 296, 298, 300, 309, 311). Health care costs in the year before and following hip arthroscopy were compared between those with or without depression or anxiety. We also compared the number of patients in each group who filled a narcotic pain prescription within 180 days before surgery as well as >60 or >90 days after hip arthroscopy. RESULTS: Depression or anxiety claims were seen in 5,208/14,830 patients (35.1%) before surgery. A significantly greater proportion of those with preoperative depression or anxiety filled opioid-related prescriptions in the 6 months before surgery (36.2% vs 25.6%, P < .0001) and both >60 days (31.3% vs 24.7%, P < .0001) and >90 days after surgery (29.5% vs 23.4%, P < .0001). The group with preoperative depression or anxiety had significantly greater health care costs both before ($8,775 vs $5,674, P < .0001) and following surgery ($5,287 vs $3,908, P < .0001). CONCLUSIONS: Both before and following hip arthroscopy, opioid use and health care costs were significantly greater for FAI patients with comorbid depression or anxiety. LEVEL OF EVIDENCE: Level III, retrospective comparative therapeutic study.

PURPOSE: Elevated synovial fluid (SF) concentrations of proinflammatory cytokines, degradative enzymes, and cartilage breakdown markers at the time of anterior cruciate ligament (ACL) reconstruction are associated with worse postoperative patient-reported outcomes and cartilage quality. However, it remains unclear if this is due to a more robust or dysregulated inflammatory response or is a function of a more severe injury. The objective of this study was to evaluate the association of the molecular composition of the SF, patient demographics, and injury characteristics to cartilage degradation after acute ACL injury. METHODS: We performed a cluster analysis of SF concentrations of proinflammatory and anti-inflammatory cytokines, and biomarkers of cartilage degradation, bony remodeling, and hemarthrosis. We evaluated the association of biomarker clusters with patient demographics, days between injury, Visual Analogue Scale pain, SF aspirate volumes, and bone bruise volumes measured on magnetic resonance imaging. RESULTS: Two clusters were identified from the 35 patients included in this analysis, dysregulated inflammation and low inflammation. The dysregulated inflammation cluster consisted of 10 patients and demonstrated significantly greater concentrations of biomarkers of cartilage degradation (P < 0.05) as well as a lower ratio of anti-inflammatory to proinflammatory cytokines (P = 0.053) when compared with the low inflammation cluster. Patient demographics, bone bruise volumes, SF aspirate volumes, pain, and concomitant injuries did not differ between clusters. CONCLUSIONS: A subset of patients exhibited dysregulation of the inflammatory response after acute ACL injury which may increase the risk of posttraumatic osteoarthritis. This response does not appear to be a function of injury severity.

BACKGROUND: The majority of patients develop posttraumatic osteoarthritis within 15 years of anterior cruciate ligament (ACL) injury. Inflammatory and chondrodegenerative biomarkers have been associated with both pain and the progression of osteoarthritis; however, it remains unclear if preoperative biomarkers differ for patients with inferior postoperative outcomes. HYPOTHESIS/PURPOSE: The purpose of this pilot study was to compare biomarkers collected on the day of ACL reconstruction between patients with "good" or "poor" 2-year postoperative outcomes. We hypothesized that inflammatory cytokines and chondrodegenerative biomarker concentrations would be significantly greater in patients with poorer outcomes. STUDY DESIGN: Prospective cohort design. METHODS: 22 patients (9 females, 13 males; age = 19.5 ± 4.1 years; BMI = 24.1 ± 3.6 kg/m2) previously enrolled in a randomized trial evaluating early anti-inflammatory treatment after ACL injury. Biomarkers of chondrodegeneration and inflammation were assessed from synovial fluid (sf) samples collected on the day of ACL reconstruction. Participants completed Knee Injury and Osteoarthritis Outcome Score (KOOS) and International Knee Documentation Committee (IKDC) questionnaires two years following surgery. Patients were then categorized based on whether their KOOS Quality of Life (QOL) score surpassed the Patient Acceptable Symptom State (PASS) threshold of 62.5 points or the IKDC PASS threshold of 75.9 points. RESULTS: Patients that failed to reach the QOL PASS threshold after surgery (n = 6, 27%) had significantly greater sf interleukin-1 alpha (IL-1α; p = 0.004), IL-1 receptor antagonist (IL-1ra; p = 0.03), and matrix metalloproteinase-9 (MMP-9; p = 0.01) concentrations on the day of surgery. Patients that failed to reach the IKDC PASS threshold (n = 9, 41%) had significantly greater sf IL-1α (p = 0.02). CONCLUSION: These pilot data suggest that initial biochemical changes after injury may be an indicator of poor outcomes that are not mitigated by surgical stabilization alone. Biological adjuvant treatment in addition to ACL reconstruction may be beneficial; however, these data should be used for hypothesis generation and more definitive randomized clinical trials are necessary.
