Abstract
SYNOPSIS: Two recent randomized-controlled trials showed promising results of local corticosteroid injections combined with exercise therapy for Achilles tendinopathy and plantar fasciopathy. Should clinicians go back to using corticosteroid injections to treat tendinopathy? Are corticosteroids back (baby)? In this viewpoint we critically appraise the new evidence and humbly share our clinical reasoning when advising athletes about corticosteroid injections in practice. Our goal is to help clinicians decide what to do and what to recommend to patients. We prioritize the risk for higher recurrence rates and tendon rupture when weighing the reasonable treatment options for tendinopathy, and recommend against using corticosteroid injections. The best systematic review evidence shows that local corticosteroid injections are not effective for tendinopathies after the first few weeks, and produce worse long-term outcomes compared to other treatments. For now, we consider corticosteroid injections remain terminated. J Orthop Sports Phys Ther 2023;53(11):1-4. Epub: 28 July 2023. doi:10.2519/jospt.2023.11875.

Abstract
Achilles' tendon (AT) injuries such as ruptures and tendinopathies have experienced a dramatic rise in the mid- to older-aged population. Given that the AT plays a key role at all stages of locomotion, unsuccessful rehabilitation after injury often leads to long-term, deleterious health consequences. Understanding healthy in vivo strains as well as the complex muscle-tendon unit interactions will improve access to the underlying aetiology of injuries and how their functionality can be effectively restored post-injury. The goals of this survey of the literature with a systematic search were to provide a benchmark of healthy AT strains measured in vivo during functional activities and identify the sources of variability observed in the results. Two databases were searched, and all articles that provided measured in vivo peak strains or the change in strain with respect to time were included. In total, 107 articles that reported subjects over the age of 18 years with no prior AT injury and measured while performing functional activities such as voluntary contractions, walking, running, jumping, or jump landing were included in this review. In general, unclear anatomical definitions of the sub-tendon and aponeurosis structures have led to considerable confusion in the literature. MRI, ultrasound, and motion capture were the predominant approaches, sometimes coupled with modelling. The measured peak strains increased from 4% to over 10% from contractions, to walking, running, and jumping, in that order. Importantly, measured AT strains were heavily dependent on measurement location, measurement method, measurement protocol, individual AT geometry, and mechanical properties, as well as instantaneous kinematics and kinetics of the studied activity. Through a comprehensive review of approaches and results, this survey of the literature therefore converges to a united terminology of the structures and their common underlying characteristics and presents the state-of-knowledge on their functional strain patterns.

Abstract
Background There continues to be controversy regarding treatment options for Achilles tendon ruptures (ATR). The aim of our study is to compare outcomes between operatively and nonoperatively managed Achilles ruptures in young adults (age 18-30 years), which has not been previously evaluated. Methods At a single institution, all patients aged 18-30 years at time of injury who underwent treatment for an acute ATR from 2014 to 2021 were evaluated. Medical records were reviewed to collect demographics, dates of injury and treatment, smoking status, body mass index (BMI), Charlson Comorbidity Index (CCI), rate of deep venous thrombosis (DVT) after treatment, and rate of rerupture. Patients then completed Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) and pain interference (PI) questionnaires. Mann-Whitney nonparametric testing was used to evaluate for any statistical differences in PROMIS scores. Results Sixty-six operative patients qualified and 28 (42%) participated. Thirty-seven nonoperative patients qualified and 14 (38%) participated. All patients had a CCI of 0. One patient in the operative cohort and 2 in the nonoperative reported active smoking. In the operative and nonoperative cohorts, respectively, the average age was 24.4 and 27.8 years; average BMI 26.5 (SD = 4.8) and 27.3 (SD = 4.3, P = .52); DVT rates 4 (6.1%) and 2 (5.4%); and rerupture rates 2 (3.0%) and 1 (2.7%), respectively. PROMIS scores did not differ in the operative and nonoperative groups: PROMIS PF mean of 60.4 (SD = 9.8) and 62.9 (SD = 9.1), respectively (P = .33); as well as PROMIS PI mean of 44.6 (SD = 5.9) and 43.9 (SD = 6.5), respectively (P = .59). Conclusion This study should be interpreted with the understanding that we had a considerable loss to follow-up rate. In the study cohort, we found that young adults with ATR may be considered for either operative or nonoperative management. Rates of DVT, rates of rerupture, and PROMIS scores were not dissimilar between the 2 cohorts. Level of Evidence Level III, retrospective cohort study.

Abstract
Background No consensus exists regarding the superiority of operative versus nonoperative management for Achilles tendon ruptures, as multiple randomized controlled trials conducted since the advent of early mobilization protocols have found outcomes for these 2 interventions to be more similar than were previously held. Purpose To use a large national database to (1) compare reoperation and complication rates between operative and nonoperative treatment of acute Achilles tendon ruptures and (2) evaluate trends in treatment and cost over time. Study Design Cohort study; Level of evidence, 3. Methods The MarketScan Commercial Claims and Encounters database was used to identify an unmatched cohort of 31,515 patients who sustained primary Achilles tendon ruptures between 2007 and 2015. Patients were stratified into operative and nonoperative treatment groups, and a propensity score-a matching algorithm-was used to establish a matched cohort of 17,996 patients (n = 8993 per treatment group). Reoperation rates, complications, and aggregate treatment costs were compared between groups with an alpha level of .05. A number needed to harm (NNH) was calculated from the absolute risk difference in complications between cohorts. Results The operative cohort experienced a significantly larger total number of complications within 30 days of injury (1026 vs 917; P = .0088). The absolute increase in cumulative risk was 1.2% with operative treatment, which resulted in an NNH of 83. Neither 1-year (1.1% [operative] vs 1.3% [nonoperative]; P = .1201) nor 2-year reoperation rates (1.9% [operative] vs 2% [nonoperative]; P = .2810) were significantly different. Operative care was more expensive than nonoperative care at 9 months and 2 years after injury; however, there was no difference in cost between treatments at 5 years. Before matching, the rate of surgical repair for Achilles tendon rupture remained stable, from 69.7% to 71.7% between 2007 and 2015, indicating little change in practice in the United States. Conclusion Results indicated no differences in reoperation rates between operative and nonoperative management of Achilles tendon ruptures. Operative management was associated with an increased risk of complications and higher initial costs, which dissipated over time. Between 2007 and 2015 the proportion of Achilles tendon ruptures managed operatively remained similar despite increasing evidence that nonoperative management of Achilles tendon rupture may provide equivalent outcomes.

Abstract
BACKGROUND Recent literature suggests that functional treatment of acute non-insertional Achilles tendon ruptures yields outcomes (re-rupture and function) similar to those of surgery, but does not address the unique issues in treating high performance athletes or other high demand patients. METHODS Decision analysis was used to develop an estimate of outcome utility for both types of treatment using published Costs and Quality-Adjusted Life Years (QALYs) values. The expected value for either treatment was then calculated for high, intermediate, and normal demand patients, using the specific functional needs of the patients. RESULTS Nonoperative treatment is the preferred management for normal demand patients, while high and intermediate demand patients are more likely to experience better expected functional outcomes from surgery. CONCLUSION The combination of a decision analysis and expected value analysis provides evidence-based support for the existing intuitive recommendations that favor surgical treatment in elite athletes and other high demand patients.

Early analysis shows that endoscopic flexor hallucis longus transfer has a promising cost-effectiveness profile in the treatment of acute Achilles tendon ruptures.

Abstract
PURPOSE Current options for treating an Achilles tendon rupture (ATR) include conservative and surgical approaches. Endoscopic flexor hallucis longus (FHL) transfer has been recently proposed to treat acute ruptures, but its cost-effectiveness potential remains to be evaluated. Therefore, the objective of this study was to perform an early cost-effectiveness analysis of endoscopic FHL transfer for acute ATRs, comparing the costs and benefits of current treatments from a societal perspective. METHODS A conceptual model was created, with a decision tree, to outline the main health events during the treatment of an acute ATR. The model was parameterized using secondary data. A systematic review of the literature was conducted to gather information on the outcomes of current treatments. Data related to outcomes of endoscopic FHL transfers in acute Achilles ruptures was obtained from a single prospective study. Analysis was limited to the two first years. The incremental cost-effectiveness ratio was the main outcome used to determine the preferred strategy. A willingness-to-pay threshold of $100,000 per quality-adjusted life-year was used. Sensitivity analyses were performed to determine whether changes in input parameters would cause significant deviation from the reference case results. Specifically, a probability sensitivity analysis was conducted using Monte Carlo simulations, and a one-way sensitivity analysis was conducted by sequentially varying each model parameter within a given range. RESULTS For the reference case, incremental cost-effectiveness ratios exceeded the willingness-to-pay threshold for all the surgical approaches. Overall, primary treatment was the main cost driver. Conservative treatment showed the highest direct costs related to the treatment of complications. In the probabilistic sensitivity analysis, at a willingness-to-pay threshold of $100,000, open surgery was cost-effective in 50.9%, minimally invasive surgery in 55.8%, and endoscopic FHL transfer in 72% of the iterations. The model was most sensitive to parameters related to treatment utilities, followed by the costs of primary treatments. CONCLUSION Surgical treatments have a moderate likelihood of being cost-effective at a willingness-to-pay threshold of $100,000, with endoscopic FHL transfer showing the highest likelihood. Following injury, interventions to improve health-related quality of life may be better suited for improved cost-effectiveness. LEVEL OF EVIDENCE Level III.

Abstract
Approved therapies for tendon diseases have not yet changed the clinical practice of symptomatic pain treatment and physiotherapy. This review article summarizes advances in the development of novel drugs, biologic products, and biomaterial therapies for tendon diseases with perspectives for translation of integrated therapies. Shifting from targeting symptom relief toward disease modification and prevention of disease progression may open new avenues for therapies. Deep evidence-based clinical, cellular, and molecular characterization of the underlying pathology of tendon diseases, as well as therapeutic delivery optimization and establishment of multidiscipline interorganizational collaboration platforms, may accelerate the discovery and translation of transformative therapies for tendon diseases.

Abstract
BACKGROUND There is no current consensus on whether to use an open or minimally invasive (MIS) approach for Achilles tendon repair after acute rupture. We hypothesized that patients in both open and MIS groups would have improved patient-reported outcome scores using the PROMIS system postoperatively, but that there would be minimal differences in these scores and complication rates between operative techniques. METHODS A total of 185 patients who underwent surgery for an acute, unilateral Achilles tendon rupture between January 2016 and June 2019, with minimum 1-year follow-up were included in the cohort studied. The minimally invasive group was defined by use of a commercially available minimally invasive device through a smaller surgical incision (n=118). The open repair group did not use the device, and suture repair was performed through larger surgical incisions (n=67). Postoperative protocols were similar between groups. Preoperative and postoperative PROMIS scores were collected prospectively through our institution's registry. Demographics and complications were recorded. RESULTS PROMIS scores overall improved in both study groups after operative repair. No significant differences in postoperative PROMIS scores were observed between the open and MIS repair groups. There were also no significant differences in complication rates between groups. Overall, 19.5% of patients in the MIS group had at least 1 postoperative complication (8.5% deep vein thrombosis [DVT], 3.3% rerupture, 1.7% sural nerve injury, 2.5% infection), compared to 16.4% in the open group (9.0% DVT, 1.5% rerupture, 1.5% sural nerve injury, 0% infection). CONCLUSION Patients undergoing either minimally invasive or open Achilles tendon repair after acute rupture have similar PROMIS outcomes and complication types and incidences.

Abstract
BACKGROUND Patellar tendinopathy is common. The success of traditional management, including isometric or eccentric exercises combined with shockwave therapy and even surgery, is limited. Therefore, it is important to determine whether biological treatments such as ultrasound-guided intratendinous and peritendinous injections of autologous expanded bone marrow mesenchymal stem cells (BM-MSCs) or leukocyte-poor platelet-rich plasma (Lp-PRP) improve clinical outcomes in athletic patients with patellar tendinopathy. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS A prospective, double-blinded, randomized, 2-arm parallel group, active controlled, phase 1/2 single-center clinical study was performed in patients who had proximal patellar tendinopathy with a lesion >3 mm. A total of 20 participants (age 18-48 years) with pain for >4 months (mean, 23.6 months) and unresponsive to nonoperative treatments were randomized into 2 groups. Of these, 10 participants were treated with BM-MSC (20 × 106 cells) and 10 with Lp-PRP. Both groups performed the same postintervention rehabilitation protocol. Outcomes included the Victorian Institute of Sport Assessment for pain (VISA-P), self-reported tendon pain during activity (visual analog scale [VAS]), muscle function by dynamometry, tendon thickness and intratendinous vascularity by ultrasonographic imaging and Doppler signal, ultrasound tissue characterization (UTC) echo type changes, and magnetic resonance imaging (MRI) T2-weighted mapping changes. Participants were followed longitudinally for 6 months. RESULTS The average VAS scores improved in both groups at all time points, and there was a significant reduction in pain during sporting activities (P < .05). In both groups, the average mean VISA-P scores at 6 months were significantly increased compared with baseline (66 BM-MSC group and 72.90 Lp-PRP group), with no significant differences in VAS or VISA-P scores between the groups. There were statistically significant greater improvements in tendon structure on 2-dimensional ultrasound and UTC in the BM-MSC group compared with the Lp-PRP group at 6 months. Similarly, the BM-MSC group demonstrated significant evidence of restoration of tendon structure on MRI compared with the Lp-PRP group at 6 months. Only the participants in the BM-MSC group showed evidence of normalization of tendon structure, with statistically significant differences between the groups on T2-weighted, fat-saturated sagittal and coronal scans and hypersignal in T2-weighted on spin-echo T2-weighted coronal MRI scan. Both treatments were safe, and no significant adverse events were reported in either group. CONCLUSION Treatment with BM-MSC or Lp-PRP in combination with rehabilitation in chronic patellar tendinopathy is effective in reducing pain and improving activity levels in active participants. Participants who received BM-MSC treatment demonstrated greater improvement in tendon structure compared with those who received Lp-PRP.

Abstract
OBJECTIVE Musculoskeletal conditions of the foot and ankle are common, yet the cost-effectiveness of the variety of treatments available is not well defined. The aim of this systematic review was therefore to identify, appraise and synthesise the literature pertaining to the cost-effectiveness of interventions for musculoskeletal foot and ankle conditions. METHODS Electronic databases were searched for studies presenting economic evaluations of non-surgical and surgical treatments for acute or chronic musculoskeletal conditions of the foot and ankle. Data on cost, incremental cost-effectiveness and quality-adjusted life years for each intervention and comparison were extracted. Risk of bias was assessed using the Drummond checklist for economic studies (range 0-35). RESULTS Thirty-six studies were identified reporting non-surgical interventions (n=10), non-surgical versus surgical interventions (n=14) and surgical interventions (n=12). The most common conditions were osteoarthritis, ankle fracture and Achilles tendon rupture. The strongest economic evaluations were for interventions managing end-stage ankle osteoarthritis, ankle sprain, ankle fracture, calcaneal fracture, and Achilles tendon rupture. Total ankle replacement and ankle arthrodesis for end-stage ankle osteoarthritis, in particular, have been demonstrated through high-quality studies to be cost-effective compared to the non-surgical alternative. CONCLUSION Selected interventions for musculoskeletal foot and ankle conditions dominate comparators, whereas others require thoughtful consideration as they provide better clinical improvements, but at an increased cost. Researchers should consider measuring and reporting costs alongside clinical outcome to provide context when determining the appropriateness of interventions for other foot and ankle complaints to best inform future clinical practice guidelines.
