The Effect of Greater Area Deprivation and Medicaid Insurance Status on Timing of Care and Rate of Reinjury After Anterior Cruciate Ligament Reconstruction.

Background: Lower socioeconomic status and public insurance lead to a longer delay to surgery and a higher likelihood of concomitant pathology before undergoing anterior cruciate ligament reconstruction (ACLR). However, few studies have examined the influence of community deprivation on ACLR timing and outcomes. Purpose/Hypothesis: The primary aim of this study was to define the effect of the area deprivation index (ADI) and insurance classification on access to orthopaedic care after an ACL rupture, and the secondary aim was to determine whether these variables were associated with a second ACL injury after primary ACLR. It was hypothesized that patients with a greater national ADI percentile and Medicaid insurance would experience longer delays to care and an increased risk of reinjury after ACLR. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective study was performed to evaluate patients undergoing primary ACLR between 2016 and 2019. The national ADI percentile was obtained utilizing the Neighborhood Atlas website. The relationship between national ADI percentile and care characteristics (eg, time to specialized care) was investigated using the Spearman rho correlation coefficient (r). The association between patient and care characteristics and second ACL injury after the index procedure (ie, graft rerupture or contralateral ACL rupture) was investigated using binary logistic regression. Results: A total of 197 patients met the inclusion criteria. Longer times from injury to surgery (r = 0.238; P < .001) and from specialized care to surgery (r = 0.217; P = .002) were associated with a greater national ADI percentile. The second injury group reported significantly greater national ADI (P = .026) and included a greater percentage of patients with Medicaid insurance (31.3%) compared with the no second injury group. Patients experienced 5.1% greater odds of a second ACL injury for each additional month between evaluation and surgery. Conclusion: Greater national ADI percentile and Medicaid insurance status were associated with adverse ACLR timing and outcomes. Patients with a greater national ADI percentile took significantly longer to obtain surgery after ACL injury. Those who sustained a second ACL injury after ACLR had an overall higher mean national ADI percentile and included a greater proportion of patients with Medicaid compared with those who did not sustain a second ACL injury. Future studies should critically investigate the underlying factors of these associations to reach equity in orthopaedic care.

A Research and Clinical Framework for Understanding Achilles Injury in Female Collegiate Gymnasts.

ABSTRACT: Gymnastics is a popular sport with a high injury rate, particularly at the collegiate level. Achilles tendon rupture is a catastrophic injury with career-changing impact. Over the last decade, there has been a growing incidence of Achilles tendon ruptures, especially in female gymnasts. Currently, neither the effects of contributing risk factors on Achilles tendon rupture nor the research frameworks to guide future intervention strategies have been well described. This article reviews the functional anatomy and mechanical properties of the Achilles tendon, provides precollegiate and collegiate intrinsic and extrinsic risk factors for Achilles tendon rupture, and proposes a research framework to address this injury from a systemic perspective. Potential clinical interventions to mitigate Achilles tendon injury are proposed based on currently available peer-reviewed evidence.

Orthobiologic Treatment of Throwing Related Injuries in Sport: A Focused Review of the Published Literature.

ABSTRACT: Because of the growth and development of orthobiologics, in particular platelet-rich plasma, as a potential treatment modality in sports related injuries, it is imperative that providers are aware of the up-to-date published data on the usage of this treatment. While some data are promising, prospective studies are needed to determine the effectiveness of platelet-rich plasma treatment for throwing related injuries. There are limitations with all of the published data that include their retrospective nature, heterogeneity between study designs, and platelet-rich plasma characteristics if reported. While platelet-rich plasma may be used as a likely safe adjuvant to conservative and surgical treatments, prospective randomized controlled studies using appropriately reported platelet-rich plasma concentrations and characteristics will help physicians make more definitive recommendations in regard to platelet-rich plasma treatment. Based on the currently available published data, this treatment may be trialed in the right setting and based on severity and location of injury.

Link Between the Female Athlete Triad and Gymnastics-Related Injury in Retired Collegiate Gymnasts.

OBJECTIVES: To compare gymnastics-related injuries between former collegiate gymnasts who did and did not report components of the female athlete triad (Triad) during college, including disordered eating or menstrual irregularity. We hypothesized that athletes reporting these 2 triad symptoms would have higher rates of time loss injury and injuries requiring surgery. DESIGN: Retrospective case-control. SETTING: Online survey. PATIENTS: Four hundred seventy former collegiate gymnasts. INTERVENTIONS: Athletes completed online survey distributed through social media. MAIN OUTCOME MEASURES: Participants were grouped based on self-reported menstrual irregularity and disordered eating during college. We compared time loss injuries, injuries resulting in surgery, and injury locations between the groups using χ2 analyses. RESULTS: Seventy percent (n = 328) of participants in this study reported a time loss college injury without surgery, and 42% (n = 199) reported an injury during college that required surgical treatment. A significantly greater proportion of gymnasts with only disordered eating reported a time loss gymnastics injury (without surgery) compared with those who reported only menstrual irregularity during college (79% vs 64%; P =0 .03). A significantly greater proportion of the disordered eating-only group reported a spine injury compared with the menstrual irregularity-only group (P = 0.007) and the group who reported neither menstrual irregularity nor disordered eating (P = 0.006). CONCLUSIONS: College gymnasts who experienced disordered eating were more likely to experience a nonsurgical time loss injury while in college, as well as spine injury compared with those with menstrual irregularity. Sports medicine providers should be aware of the association between injuries and individual components of Triad in gymnasts beyond bone stress injuries.

Operative vs. nonoperative treatment of distal biceps ruptures: a systematic review and meta-analysis.

BACKGROUND AND HYPOTHESIS: Ruptures of the distal biceps tendon are most commonly due to traumatic eccentric loading in the middle-aged male population and can result in functional deficits. Although surgical repair has been demonstrated to result in excellent outcomes, there are few comparative studies that show clear functional benefits over nonoperative management. The aim of this systematic review and meta-analysis is to compare the functional outcomes of operative and nonoperative management for these injuries. We hypothesized that operative treatment would be associated with significantly superior outcomes. METHODS: According to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of the literature was performed using MEDLINE, SPORTDiscus, CINAHL (Cumulative Index to Nursing and Allied Health Literature), CENTRAL (Cochrane Central Registry of Controlled Trials), Embase, and Web of Science databases. Outcomes of interest included range of motion (ROM), strength, endurance, and patient-reported outcomes including Disabilities of the Arm, Shoulder and Hand (DASH), Mayo Elbow Performance Score (MEPS), and visual analog scale (VAS) for pain scores. Summary effect estimates of the mean difference between operative and nonoperative management for each outcome were estimated in mixed effects models. RESULTS: Of an initially identified 6478 studies, 62 reported outcomes for a total of 2481 cases (2402 operative, 79 nonoperative), with an overall average age of 47.4 years (47.3 for operative, 50.3 for nonoperative). There were 2273 (98.5%) males and 35 (1.5%) females among operative cases, whereas all 79 (100%) nonoperative cases were males. Operative management was associated with a significantly higher flexion strength (mean difference, 25.67%; P < .0001), supination strength (mean difference, 27.56%; P < .0001), flexion endurance (mean difference, 11.12%; P = .0268), and supination endurance (mean difference, 33.86%; P < .0001). Patient-reported DASH and MEPS were also significantly superior in patients who underwent surgical repair, with mean differences of -7.81 (P < .0001) and 7.41 (P = .0224), respectively. Comparative analyses for ROM and pain VAS were not performed because of limited reporting in the literature for nonoperative management. CONCLUSION: This study represents the first systematic review and meta-analysis to compare functional and clinical outcomes following operative and nonoperative treatment of distal biceps tendon ruptures. Operative treatment resulted in superior elbow and forearm strength and endurance, as well as superior DASH and MEPS.

No Difference in Complications Between Elbow Ulnar Collateral Ligament Reconstruction With the Docking and Modified Jobe Techniques: A Systematic Review and Meta-analysis.

BACKGROUND: The most commonly used techniques for elbow ulnar collateral ligament reconstruction (UCLR) are the docking and modified Jobe figure-of-8 techniques. Previous literature has suggested that UCLR with the docking technique is associated with fewer complications; however, these studies included results from the original classic Jobe technique without controlling for the effects of flexor pronator mass (FPM) detachment and routine submuscular ulnar nerve transposition (UNT). PURPOSE/HYPOTHESIS: This study sought to compare the rates of complications and subsequent unplanned surgical procedures between the docking and figure-of-8 techniques. We hypothesized that there would be no significant difference in the rates of complications or subsequent unplanned surgical procedures between the techniques when the FPM was preserved and no routine submuscular UNT was performed. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 4. METHODS: This study was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A series of mixed-effects multivariate metaregression models were implemented using the restricted maximum likelihood method. Complications and subsequent unplanned surgical procedures were modeled as Freeman-Tukey transformed incidence rates for variance stabilization, and nerve-specific complications were assessed as the Freeman-Tukey transformed proportion of cases, with back-transformation to estimate summary effects. RESULTS: There were 19 studies eligible for qualitative analysis, consisting of 1788 cases of UCLR (303 docking, 1485 figure-of-8), 18 of which were suitable for quantitative analysis (1769 cases; 291 docking, 1478 figure-of-8). A total of 338 complications were reported (17 for docking, 321 for figure-of-8), the majority of which were nerve related. Additionally, a total of 75 subsequent unplanned surgical procedures were related to the index UCLR procedure. There was no significant difference in the rate of complications (P = .146) or proportion of cases with nerve-specific complications (P = .127) between the docking and figure-of-8 techniques when controlling for FPM preservation versus detachment with submuscular UNT. FPM detachment with submuscular UNT was independently associated with a significantly higher proportion of postoperative nerve-related complications (P = .004). There was also no significant difference in the rates of subsequent unplanned surgical procedures between the docking and figure-of-8 techniques (P = .961), although FPM detachment with routine submuscular UNT was independently associated with a significantly higher incidence of subsequent unplanned surgical procedures. CONCLUSION: The results of this study demonstrate no significant difference in the rates of complications or subsequent unplanned surgical procedures between the figure-of-8 and docking techniques for UCLR when controlling for FPM preservation versus detachment with submuscular UNT. With modern muscle-sparing approaches and avoiding submuscular UNT, the modified Jobe technique does not differ significantly from the docking technique in terms of complication rates, proportions of cases with nerve-specific complications, or rates of subsequent unplanned surgical procedures.

Modified Jobe Versus Docking Technique for Elbow Ulnar Collateral Ligament Reconstruction: A Systematic Review and Meta-analysis of Clinical Outcomes.

BACKGROUND: The modified Jobe and docking techniques are the most common techniques used for elbow ulnar collateral ligament (UCL) reconstruction. Previous systematic reviews have suggested that the docking technique results in superior outcomes as compared with the Jobe (figure-of-8) technique. However, these included results from earlier studies in which the flexor-pronator mass (FPM) was detached and an obligatory submuscular ulnar nerve transposition was performed. PURPOSE/HYPOTHESIS: The purpose was to compare the outcomes and return-to-play (RTP) time between the docking and figure-of-8 techniques for UCL reconstruction. We hypothesized that there would be no significant difference in the proportion of excellent outcomes between techniques when the FPM was preserved and no obligatory submuscular ulnar nerve transposition was performed. We also hypothesized that there would be no significant difference in RTP time between techniques. STUDY DESIGN: Systematic review and meta-analysis. METHODS: This study was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. In the primary analysis, techniques were compared in random effects models by using the restricted maximum likelihood method, with weighted effect sizes calculated as the Freeman-Tukey double-arcsine transformed proportion of excellent outcomes for variance stabilization and with summary effects estimated from the inverse double-arcsine transformation per the harmonic mean of the sample sizes. Mean RTP times for techniques were compared in a separate model. RESULTS: There were 21 eligible articles identified, with results for 1842 UCL reconstructions (n = 320, docking; n = 1466, figure-of-8). Without controlling for the effects of flexor-pronator detachment and submuscular ulnar nerve transposition, a significantly larger proportion of excellent outcomes was observed with docking reconstruction (86.58%; 95% CI, 80.42%-91.85%) than with figure-of-8 reconstruction (76.76%; 95% CI, 69.65%-83.25%; P = .031); however, there was no significant difference between techniques when controlling for FPM preservation or detachment with submuscular nerve transposition (P = .139). There was no significant difference between techniques in time to return to sports (P = .729), although no reconstructions with FPM detachment and submuscular ulnar nerve transposition were available for RTP time analysis. CONCLUSION: There was no significant difference in the proportion of excellent Conway Scale outcomes or RTP time between the docking and modified Jobe techniques for UCL reconstruction when the FPM was preserved and routine submuscular ulnar nerve transposition was not performed.

Treatment of Pectoralis Major Tendon Tears: A Systematic Review and Meta-analysis of Repair Timing and Fixation Methods.

BACKGROUND: Repair of torn pectoralis major tendons is generally considered superior to nonoperative management, but there is a paucity of comparative data to demonstrate ideal repair timing and fixation methods. PURPOSE/HYPOTHESIS: The purpose was to compare the outcomes between acute and chronic repair and among the various methods of fixation (transosseous tunnels, cortical buttons, suture anchors, screws with washers, and direct repair). It was hypothesized that acute repair would have superior outcomes and there would be similar outcomes among the various methods of fixation. STUDY DESIGN: Meta-analysis. METHODS: In accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic review of the literature was completed through MEDLINE, SPORTDiscus, CINAHL, Cochrane, Embase, and Web of Science databases. English-language studies were included with a minimum of 6 months' mean follow-up and 5 cases per study. MINORS (Methodological Index for Nonrandomized Studies) was utilized to assess the quality of the existing literature. Analysis of mechanisms of injury and meta-analysis of pooled outcomes were completed. Pooled effect sizes were calculated from random effects models. Continuous variables were assessed via mixed model analysis, with the individual study designated as a random effect and the desired treatment for comparison as a fixed effect. Bivariate frequency data were transformed through Freeman-Tukey log-linear transformation for variance stabilization and then assessed through a mixed model with a study-level random effect and subsequently back-transformed. Significance was set at P < .05. RESULTS: Twenty articles with 384 injuries met the inclusion criteria for comparison. All patients were male, with 61.9% of injuries occurring during weight training, at a mean age of 31.53 years, and with a mean follow-up of 30.12 months. Included studies scored a mean (SD) 15.53 ± 4.26 (range, 7.0-23.3) by MINORS criteria. Acute repair was significantly superior to chronic repair, with a relative improvement of functional outcome by 0.85 (P = .004) and satisfaction with cosmesis by 20.50% (P = .003). There was a trend toward acute repair having a higher proportion of patients who were pain-free (34.47%, P = .064). There were no significant differences among the methods of fixation for repair. CONCLUSION: Acute repair of pectoralis major tendon tears resulted in significantly superior functional outcomes and cosmesis satisfaction with a trend toward a higher proportion of patients who were pain-free. There were no significant differences among the methods of fixation for repair.

Treatment of Pectoralis Major Tendon Tears: A Systematic Review and Meta-analysis of Operative and Nonoperative Treatment.

BACKGROUND: The incidence of pectoralis major tendon tears is increasing, and repair is generally considered; however, a paucity of comparative data are available to demonstrate the superiority of operative treatment. PURPOSE/HYPOTHESIS: The purpose of this study is to compare the outcomes of operative and nonoperative treatment of pectoralis major tendon tears. We hypothesized that repair would result in superior outcomes compared with nonoperative treatment. METHODS: In accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic review of the literature was completed by use of MEDLINE, SPORTDiscus, CINAHL, Cochrane, EMBASE, and Web of Science databases. We included English-language studies that had a minimum of 6 months of average follow-up and 5 cases per study. The MINORS (Methodological Index for Non-Randomized Studies) was used to assess the quality of the existing literature. Meta-analysis of pooled mechanisms of injury and outcomes was completed. Pooled effect sizes were calculated from random-effects models. Continuous variables were assessed by use of mixed-model analysis, with the individual study designated as a random effect and the desired treatment for comparison as a fixed effect. Bivariate frequency data were transformed via the Freeman-Tukey log-linear transformation for variance stabilization and then assessed through use of a mixed model with a study level random effect and subsequently back-transformed. Significance was set at P < .05. RESULTS: A total of 23 articles with 664 injuries met the inclusion criteria for comparison. All patients were male, with an average age of 31.48 years; 63.2% of injuries occurred during weight training, and the average follow-up was 37.02 months. Included studies had moderately high methodological quality. Operative treatment was significantly superior to nonoperative treatment, with relative improvements of functional outcome by 23.33% (0.70 improvement by Bak criteria which is scored 1-4; P = .027), full isometric strength 77.07% (P < .001), isokinetic strength 28.86% (P < .001) compared with the uninjured arm, cosmesis satisfaction 13.79% (P = .037), and resting deformity 98.85% (P < .001). The overall complication rate for operative treatment was 14.21%, including a 3.08% rate of rerupture. CONCLUSION: Pectoralis major tendon repair resulted in significantly superior outcomes compared with nonoperative treatment, with an associated 14.21% complication rate. Statistically significant improvements were noted in functional outcome, isokinetic strength, isometric strength, cosmesis, and resting deformity.
