[PMID: 38796725 DOI: 10.1002/ksa.12240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 04/05/2024] [Accepted: 04/24/2024] [Indexed: 05/28/2024]
Abstract
PURPOSE The aim of the study was to examine the impact of a deep venous thrombosis (DVT) on patient outcomes 3 years after Achilles tendon rupture (ATR) repair and if there were continued improvements between 1 and 3 years after surgery. A secondary aim was to determine risk factors associated with impaired patient outcomes in the long term. METHODS This cohort study consisted of 181 ATR-repaired patients, from two large randomized clinical trials, who attended a 3-year follow-up evaluation. Patients were postoperatively randomized to two different weight-bearing interventions compared with immobilization in a below-knee plaster cast for 2 weeks. During immobilization, screening for DVT was performed with Doppler ultrasound. At 1 and 3 years postoperatively, functional- and patient-reported outcomes were evaluated by the validated heel-rise test and self-reported questionnaire, Achilles tendon Total Rupture Score (ATRS). RESULTS In total, 76 out of 181 (42%) patients exhibited a DVT at the 2- or 6-week screening after ATR surgery. Suffering from a DVT during immobilization resulted at 3 years in a worse limb symmetry index (LSI) of heel-rise total work compared to patients without DVT, adjusted for age (DVT mean LSI 68% vs. no DVT 78%, p = 0.027). At 3 years, patients with a DVT during immobilization displayed lower ATRS (DVT median 88 vs. no DVT 93, p = 0.046), which was not significant after adjustment for age. However, patients with DVT exhibited an improvement in ATRS, LSI total work, and LSI maximum height between 1 and 3 years, which was not seen among patients without DVT. Independent risk factors for reduced patient functional outcomes at 3 years were older age, greater calf muscle hypotrophy, and suffering a DVT. CONCLUSIONS DVT during immobilization affects patients' long-term functional outcomes 3 years after ATR repair. Clinicians should adequately address risk factors contributing to impaired patient outcomes in the long term, including calf muscle hypotrophy, DVT, and older age. LEVEL OF EVIDENCE Level Ⅲ.

Abstract
Background: Deep Vein Thrombosis (DVT) is a common disease, frequently afflicting the lower limb veins of bedridden patients. Intermittent Pneumatic Compression (IPC) is often employed as an effective solution for this problem. In our study, a random selection of 264 patients underwent IPC treatment for either one or 8 hours daily. The rate of severe venous thrombosis was substantially reduced in the IPC-treated group compared to the control group. However, real-time monitoring of blood flow during IPC operation periods remains a challenge, leading to rare awareness of IPC working mechanism on thrombosis prevention. Methods: Here, microfluidic chip methodology is used to create an in vitro vein-mimicking platform integrating venous valves in a deformable channel. Whole blood of patients after knee surgery was perfused into the venous channel at a controlled flow rate obtained from patients with IPC treatment clinically. Results: According to the numerical simulations results, both of an increase in compressive pressure and a decrease in time interval of IPC device can accelarete blood flow rate and the shear stress within the vein. The vein chip experiments also reveal that the fibrin accumulation can be greatly lowered in IPC treated group, indicating less thrombosis formation in future. A time interval of 24 seconds and a maximum contraction pressure of 40 mmHg were proved to be the most effective parameters for the IPC device adopted in our clinical trail. Conclusion: This vein chip presents a novel method for observing the functional mechanisms of IPC device for DVT prevention. It provides crucial data for further standardization and optimization of IPC devices in clinical usage.

Abstract
Introduction Dense connective tissues (DCTs) such as tendon, ligament, and cartilage are important stabilizers and force transmitters in the musculoskeletal system. The healing processes after DCT injuries are highly variable, often leading to degenerative changes and poor clinical outcome. Biomarkers in relation to repair quality for human DCTs, especially tendon are lacking. This study expands our previous findings and aimed to characterize the mechanisms by which a potential biomarker of good outcomes, complement factor D (CFD), regulates tendon healing. Methods Quantitative mass spectrometry (QMS) profiling of tissue biopsies from the inflammatory phase of healing (n = 40 patients) and microdialysates from the proliferative phase of healing (n = 28 patients) were used to identify specific biomarkers for tendon healing. Further bioinformatic and experimental investigations based on primary fibroblasts and fibroblast cell line were used to confirm the identified biomarkers. Results The QMS profiling of tissue biopsies from the inflammatory phase of healing identified 769 unique proteins, and microdialysates from the proliferative phase of healing identified 1423 unique proteins in Achilles tendon rupture patients. QMS-profiling showed that CFD expression was higher during the inflammatory- and lower during the proliferative healing phase in the good outcome patients. Further bioinformatic and experimental explorations based on both inflammatory and proliferative fibroblast models demonstrated that CFD potentially improved repair by regulating cell migration and modulating collagen type I (Col1a1) expression. Moreover, it was shown that the enhanced Col1a1 expression, through increased fibroblast migration, was correlated with the validated clinical outcome. Discussion The results of the current studies characterized underlying inflammatory- and proliferative healing mechanisms by which CFD potentially improved tendon repair. These findings may lead to improved individualized treatment options, as well the development of effective therapies to promote good long-term clinical outcomes after tendon and other DCT injuries.

Abstract
Osteoporosis screening, diagnosis, and treatment have gained much attention in the health care community over the past 2 decades. During this time, creation of multispecialty awareness programs (eg, "Own the Bone," American Orthopedic Association; "Capture the Fracture," International Osteoporosis Foundation) and improvements in diagnostic protocols have been evident. Significant advances in technology have elucidated elements of genetic predisposition for decreased bone mineral density in the aging population. Additionally, several novel drug therapies have entered the market and provide more options for primary care and osteoporosis specialists to medically manage patients at risk for fragility fractures. Despite this, adherence to osteoporosis screening and treatment protocols has been surprisingly low by health care practitioners, including orthopedic surgeons. Continued awareness and education of this skeletal disorder is crucial to effectively care for our aging population. [Orthopedics. 2023;46(1):e20-e26.].

Am J Sports Med 2022; 50:3856-3865.

Abstract
BACKGROUND Deficits in calf muscle function and heel-rise performance are common after an Achilles tendon rupture (ATR) and are related to tendon elongation and calf muscle atrophy. Whether early functional mobilization (EFM) can improve calf muscle function compared with standard treatment (ST) with 2 weeks of immobilization and unloading in a plaster cast is unknown. HYPOTHESIS EFM would lead to superior recovery of heel-rise performance, as demonstrated by more symmetrical side-to-side ankle and knee joint kinematics, compared with ST. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS In total, 47 patients with an ATR were prospectively included and treated with open surgical repair and randomized 2:1 postoperatively to either EFM or ST. Overall, 29 patients were treated with a dynamic orthosis (EFM), and 18 underwent ST. At 8 weeks and 6 months after ATR repair, 3-dimensional motion analysis of heel-rise performance was conducted. At 6 months, tendon length and muscle volume were assessed with ultrasound imaging, calf muscle function with the heel-rise test, and patient-reported outcomes with the Achilles tendon Total Rupture Score. RESULTS At 8 weeks and 6 months, there were no significant group differences between the EFM and ST groups in heel-rise performance, but significant side-to-side differences in ankle and knee kinematics were detected. At 8 weeks and 6 months, both the EFM and ST groups showed a significantly decreased peak ankle plantarflexion angle and increased knee flexion angle on the injured limb compared with the uninjured limb during bilateral heel raises. Linear regression demonstrated that greater atrophy of the medial gastrocnemius muscle (P = .008) and higher body weight (P < .001) were predictors of a decreased maximum peak ankle plantarflexion angle on the injured limb at 6 months. CONCLUSION EFM after an ATR repair did not lead to superior recovery of calf muscle function, as assessed by heel-rise performance, compared with ST. Increased knee flexion seemed to be a compensatory strategy for decreased ankle plantarflexion. Medial gastrocnemius atrophy and increased body weight were additional factors associated with a decreased ankle plantarflexion angle. REGISTRATION NCT02318472 (ClinicalTrials.gov identifier).

Abstract
Background and Objective: Acute Achilles tendon rupture (AATR) is a common injury with a significant impact on daily living. Although various systematic reviews and meta-analyses have been written on the topic, no actual consensus exists on the best treatment. We aimed to collect the highest quality of evidence on the subject and to produce a document to which to refer, from the diagnosis to the final treatment. Material and Methods: Inclusion criteria were systematic reviews discussing Achilles tendon rupture, concerning either diagnostic criteria, classification, or treatment; English language; clearly stated inclusion and exclusion criteria for patients’ selection. Results: Thirteen systematic reviews were included in the study. A strong consensus exists about the higher risk of re-rupture associated with non-operative treatment and a higher risk of complications associated with surgical repair. Conclusions: The combination of minimally invasive repair and accelerated functional rehabilitation seems to offer the best results in the treatment of Achilles tendon rupture.

Abstract
Background: The effect of surgeon experience on patient outcomes after surgical Achilles tendon rupture (ATR) repair has so far been unknown. Purpose: To examine whether patient-reported and functional outcomes as well as adverse events after surgical ATR repair differ between orthopaedic specialist surgeons and resident surgeons. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively analyzed data from 295 patients treated with surgical ATR repair with standardized techniques. The level of surgeon experience (specialist vs resident) and number of adverse events (rerupture, infection, and deep venous thrombosis) were recorded. Patient-reported and functional outcomes were assessed 12 months postoperatively using the validated Achilles tendon total rupture score (ATRS) and the heel-rise test, respectively. Analysis of covariance was used to compare differences in outcomes between specialist surgeons and resident surgeons. Pearson chi-square or Fisher exact test was used for analysis of adverse events. Results: The mean ATRS at 12 months for patients operated on by resident surgeons was significantly higher compared with specialist surgeons (85.9 [95% CI, 80.3-91.5] vs 77.8 [95% CI, 73.8-81.9]; P = .028). In addition, the lateral difference (operated vs unoperated side) in mean total concentric work and number of heel-rise repetitions at 12 months was smaller in patients operated on by resident surgeons (P = .011 and 0.015, respectively). The number of adverse events did not differ significantly between the 2 groups. Conclusion: Resident surgeons achieved patient-reported and functional outcomes at least as good as those of specialist surgeons in surgical ATR repair, with a similar risk of adverse events.

[PMID: 34689989 DOI: 10.1016/j.injury.2021.10.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 09/29/2021] [Accepted: 10/10/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The primary aim was to determine independent patient, injury and management-related factors associated with symptomatic venous thromboembolism (VTE) following acute Achilles tendon rupture (ATR). The secondary aim was to suggest a clinical VTE risk assessment tool for patients with acute ATR. METHODS From 2010-2018, 984 consecutive adults (median age 47yrs, 73% [n = 714/984] male) sustaining an acute ATR were retrospectively identified. Ninety-five percent (n = 939/984) were managed non-operatively in a below-knee cast (52%, n = 507/984) or walking boot (44%, n = 432/984), with 5% (n = 45/984) undergoing primary operative repair (<6wks post-injury). VTE was diagnosed using local medical records and national imaging archives, reviewed at a mean 5yrs (range 1-10) post-injury. Multivariate logistic regression was performed to determine independent factors associated with VTE. RESULTS The incidence of VTE within 90 days of ATR was 3.6% (n = 35/984; deep vein thrombosis 2.1% [n = 21/984], pulmonary embolism 1.9% [n = 19/984]), and the median time to VTE was 24 days (interquartile range 15-44). Age ≥50yrs (adjusted OR [aOR] 2.3, p = 0.027), personal history of VTE/thrombophilia (aOR 6.1, p = 0.009) and family history of VTE (aOR 20.9, p<0.001) were independently associated with VTE following ATR. These non-modifiable risk factors were incorporated into a VTE risk assessment tool. Only 23% of patients developing VTE (n = 8/35) had a relevant personal or family history, but incorporating age ≥50yrs into the VTE risk assessment tool (alongside personal and family history) identified 69% of patients with VTE (n = 24/35). Non weight-bearing for ≥2wks after ATR was also independently associated with VTE (aOR 3.2, p = 0.026). CONCLUSIONS Age ≥50 years, personal history of VTE/thrombophilia and a positive family history were independently associated with VTE following ATR. Incorporating age into our suggested VTE risk assessment tool enhanced its sensitivity in identifying at-risk patients. Early weight-bearing in an appropriate orthosis may be beneficial to all patients in VTE risk reduction.

Abstract
BACKGROUND An acute Achilles tendon rupture (AATR) is a common injury. The controversy that has surrounded the optimal treatment options for AATRs warrants an updated meta-analysis that is comprehensive, accounts for loss to follow-up, and utilizes the now greater number of available studies for data pooling. PURPOSE To meta-analyze the rates of all complications after the treatment of AATRs with a "best-case scenario" and "worst-case scenario" analysis for rerupture rates that assumes that all patients lost to follow-up did not or did experience a rerupture, respectively. STUDY DESIGN Systematic review and meta-analysis; Level of evidence, 1. METHODS Two authors performed a systematic review of the PubMed and Embase databases according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines on February 17, 2020. The included studies were assessed in terms of the level of evidence, quality of evidence, and quality of the literature. A meta-analysis by fixed-effects models was performed if heterogeneity was low (I2 < 25%) and by random-effects models if heterogeneity was moderate to high (I2≥ 25%). RESULTS Surgical treatment was significantly favored over nonsurgical treatment for reruptures. Nonsurgical treatment was significantly favored over surgical treatment for complications other than reruptures, notably infections. Minimally invasive surgery was significantly favored over open repair for complications other than reruptures (no difference for reruptures), in particular for minor complications. CONCLUSION This meta-analysis demonstrated that surgical treatment was superior to nonsurgical treatment in terms of reruptures. However, the number needed to treat analysis produced nonmeaningful values for all treatment options, except for surgical versus nonsurgical treatment and minimally invasive surgery versus open repair. No single treatment option was revealed to be profoundly favorable with respect to every complication. The results of this meta-analysis can guide clinicians and patients in their treatment decisions that should be made jointly and on a case-by-case basis.

Abstract
Venous thromboembolism (VTE) is a common complication for critically ill patients. Intermittent pneumatic compression (IPC) is recommended for patients with high risk of bleeding. We aim to evaluate the effectiveness of IPC for thromboprophylaxis in critically ill patients. We searched PubMed, Embase, and ClinicalTrials for randomized controlled trials (RCTs) and observational studies that evaluated IPC in critically ill patients. RevMan 5.3 software was used for the meta-analysis. A total of 10 studies were included. The IPC group significantly reduced the VTE incidence compared with no thromboprophylaxis group (risk ratio [RR]: 0.35, confidence interval [CI]: 0.18-0.68, P = .002) and the IPC group also showed lower VTE incidence than the graduated compression stockings (GCS) group (RR: 0.47, CI: 0.24-0.91, P = .03). There were no significant differences between using IPC and low-molecular-weight heparin (LMWH) for VTE incidence (RR: 1.26, CI: 0.72-2.22, P = .41), but LMWH showed significantly more bleeding events. Intermittent pneumatic compression as an adjunctive treatment did not further reduce VTE incidence (RR: 0.55, CI: 0.24-1.27, P = .16). Intermittent pneumatic compression can reduce the incidence of VTE for critically ill patients, which is better than GCS and similar to LMWH, but it has no significant advantage as an adjunct therapy for thromboprophylaxis.

Abstract
INTRODUCTION Leg immobilisation in a cast or an orthosis after lower limb injuries is associated with a high risk of complications of venous thromboembolism (VTE) and hampered healing. Current pharmacoprophylaxes of VTE are inefficient and associated with adverse events. Intermittent pneumatic compression (IPC) could represent a novel, efficient and safe VTE-prophylactic alternative that may enhance injury healing. The aim of STOP leg clots is to assess the efficacy of adjuvant IPC-therapy on reduction of VTE incidence and improvement of healing in lower leg immobilised outpatients. METHODS AND ANALYSIS STOP leg clots is a multicentre randomised controlled superiority trial. Eligible patients (700 patients/arm) with either an acute ankle fracture or Achilles tendon rupture will be randomised to either addition of IPC during lower-leg immobilisation or to treatment-as-usual. The primary outcome will be the total VTE incidence, that is, symptomatic and asymptomatic deep venous thrombosis (DVT) or symptomatic pulmonary embolism (PE), during the leg immobilisation period, approximately 6-8 weeks. DVT incidence will be assessed by screening whole leg compression duplex ultrasound at removal of leg immobilisation and/or clinically diagnosed within the time of immobilisation. Symptomatic PE will be verified by CT.Secondary outcomes will include patient-reported outcome using validated questionnaires, healing evaluated by measurements of tendon callus production and changes in VTE-prophylactic mechanisms assessed by blood flow and fibrinolysis. Data analyses will be blinded and based on the intention-to-treat. ETHICS AND DISSEMINATION Ethical approval was obtained by the ethical review board in Stockholm, Sweden, Dnr 2016/1573-31. The study will be conducted in accordance with the Helsinki declaration. The results of the study will be disseminated in peer-reviewed international journals. TRIAL REGISTRATION NCT03259204. TIME SCHEDULE 1 September 2018 to 31 December 2022.

Abstract
PURPOSE Healing outcome after Achilles Tendon Rupture (ATR) is variable and unsatisfactory. Many ATR patients still exhibit pain, functional deficits and limitations in walking one-year post-surgery. The present study was designed to investigate the association between the expression of healing biomarkers and patient outcome after ATR. METHODS Tendon biopsies were collected from 25 ATR patients during surgery. At 1-year post surgery, all patients completed questionnaires; Achilles tendon Total Rupture Score (ATRS) and Foot and Ankle Outcome Score (FAOS), and were tested for functional outcomes by heel-rise test. In biopsies, FGF, COL III, FN, COL I and MMP-9 mRNA levels were assessed by quantitative RT-PCR while protein expression was studied by immunohistochemistry (IHC). RESULTS Our analysis confirmed the presence of FGF, COL III, FN, COL I and MMP-9 at mRNA and protein levels in tendon biopsies. FGF gene expression associated positively with improved total ATRS and better functional outcomes. Additionally, FGF mRNA levels were associated with less pain, less running limitations and less loss in physical activity. In addition, higher COL III mRNA expression was associated with more tendon strength. CONCLUSION Our findings indicate that FGF gene expression is associated with improved patient-reported outcome. FGF expression in surgical biopsies could potentially be used to assist the prognostic evaluation of patient outcome and may be used as a predictor for healing. However, further studies are needed to evaluate the role of FGF in Achilles tendon healing. LEVEL OF EVIDENCE II.

Abstract
Background: The Achilles tendon is the strongest tendon in human and is frequently injured, mainly in the young to middle age active population. Increasing incidence of Achilles tendon rupture (ATR) is still reported in several studies. Surgical repair and conservative treatment are two major management strategies widely adopted in ATR patients, but the consensus of the optimal treatment strategy is still debated. We aimed at thoroughly reviewing the ATR topic with additional assessments and performed a most comprehensive meta-analysis of randomized controlled trials (RCTs). Method: We comprehensively searched PubMed, Embase, Cochrane, and ClinicalTrial.gov and retrieved all RCTs comparing surgical and conservative treatment on ATR for further analysis. Two independent reviewers performed data extraction and random effect model was adopted when I 2 > 50%, with data presentation of risk ratio, risk difference, or mean difference and 95% confidence interval. Results: A total of 13 RCTs were included in this meta-analysis. A significant difference was observed in re-rupture, complication rate, adhesion to the underlying tendon, sural nerve injury, and superficial infection. A substantial reduction in re-rupture rate could be observed for surgical treatment while the complication rate was higher compared with conservative treatment. Conclusion: Surgical treatment revealed significance in reducing the re-rupture rate but was associated with a higher complication rate, while conservative treatment showed similar outcomes with a lower complication rate. Collectively, we recommend conservative treatment if patients' status and expectations are suitable, but surgeon and physician discretion is also crucial in decision making.

Abstract
PURPOSE The primary aim of this study was to assess the relationship between the metabolites lactate and pyruvate in the healing tendon after Achilles tendon rupture (ATR) and patient-reported outcome at 6 and 12 months. A secondary aim was to evaluate which underlying factors regulate lactate and pyruvate concentrations. METHODS Lactate and pyruvate concentrations were measured two weeks post-operatively in both the healing- and healthy Achilles tendon in 109 patients (90 men, 19 women; mean age 40 ± 7.9 years). Patient demographics, degree of physical activity, timing of surgery, operation time, patient-reported loading and step counts were investigated in relation to metabolite concentrations. At 6 and 12 months, the Achilles tendon Total Rupture Score (ATRS) questionnaire was used to assess patient outcome. RESULTS The mean number of steps taken during the post-operative days 1-10 was the only factor significantly related to the mean concentration of lactate (R2 = 0.34, p = 0.038), and pyruvate (R2 = 0.46, p = 0.006). Pyruvate was demonstrated as the only factor significantly associated with ATRS at both 6 months (R2 = 0.32, p = 0.003) and at 12 months (R2 = 0.37, p = 0.004) using multiple linear regression. CONCLUSION The mean concentration of pyruvate during early ATR healing may predict patient outcome at 6 and 12 months post-operatively and possibly be used as a biomarker of healing. Early mobilization with an increased number of steps taken is an important clinical strategy to improve the metabolite concentrations during healing. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Early functional mobilization (EFM) may improve patient outcome after Achilles tendon rupture (ATR). However, whether EFM affects patient outcome via changes in tendon elongation, thickening, or calf muscle atrophy is unknown. PURPOSE To analyze differences in tendon and muscle morphology recovery over time between groups treated with EFM or standard treatment after ATR repair. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS This prospective cohort study included 86 patients (20 women) with ATR repair who had a mean (SD) age of 39.3 (8.2) years and were part of a larger prospective randomized controlled trial. Patients were postoperatively randomized to immediate postoperative weightbearing and ankle motion (EFM group) or to immobilization in a below-knee plaster cast for 2 weeks (control group). Patient-reported and functional outcomes were assessed at 6 and 12 months with the Achilles Tendon Total Rupture Score and the heel-rise test for endurance. At 2 and 6 weeks and 6 and 12 months postoperatively, B-mode ultrasound imaging was performed to assess the length and cross-sectional area (CSA) of the Achilles tendon, the gastrocnemius CSA, as well as the thickness of soleus. RESULTS The Achilles Tendon Total Rupture Score for the EFM and control groups were 65.8 (18.7) and 56.8 (20.1; P = .045), respectively, at 6 months and 79.6 (15.8) and 78.9 (17.2; P = .87), respectively, at 12 months. At 2 weeks, tendon elongation was significantly more pronounced in the EFM group as compared with the control group (mean side-to-side difference, 1.88 cm vs 0.71 cm; P = .005). Subsequently, tendon elongation increased in the control group while it decreased in the EFM group so that at 6 and 12 months no significant differences between groups were found. Mean Achilles tendon elongation at 1 year was 1.73 (1.07) cm for the EFM group (n = 55) and 1.67 (0.92) cm for the control group (n = 27), with a mean difference of 0.06 cm (95% CI, 0.54 to -0.42; P = .80). Achilles tendon CSA and calf muscle atrophy displayed no significant differences between the groups; however, significant changes were demonstrated over time (P ≤ .001) in both groups. CONCLUSION EFM results in more Achilles tendon elongation at early healing, but this difference subsides over time. EFM does not seem to affect patient outcome via changes in tendon elongation, thickening, or calf muscle atrophy. REGISTRATION NCT02318472 (ClinicalTrials.gov identifier).

Venous thromboembolism in trauma patients with lower limb cast immobilization, associated risk reduction and complication using rivaroxaban. Ir J Med Sci 2020; 190:169-175.

Abstract
INTRODUCTION Several studies have shown a reduction in the rate of thromboembolic events with LMWH thromboprophylaxis in patients immobilised in lower limb cast. However, the literature is limited on the use of rivaroxaban in this setting. Therefore the aim of this study was to assess the associated impact of rivaroxaban on the incidence of venous thromboembolism in trauma patients with lower limb cast immobilisation. METHOD Adult patients treated with lower limb cast immobilisation for different types of lower limb injuries were included in this study. One cohort of patients (n = 518) received rivaroxaban thromboprophylaxis. This was compared with a historical cohort (n = 486), who received no rivaroxaban for thromboprophylaxis. RESULTS The number of patients developing VTEs in the rivaroxaban group was zero, compared with 6 cases (1.2%) in the nonrivaroxaban group p = 0.013. There were no major or minor bleeding incidences; no wound complications reported in the rivaroxaban group. All the side effects reported in association with rivaroxaban use did not require further intervention. CONCLUSION This study has shown that rivaroxaban is associated with a significant reduction in the risk of VTEs in patients with lower limb cast immobilisation without increasing the risk of bleeding or associated untoward effect. Lower limb immobilisation is high risk factor for VTE per se. However, there is still limited data in the literature to make further recommendations.

Abstract
BACKGROUND While numerous clinical studies have compared the surgical and non-surgical treatment of acute Achilles tendon rupture (ATR), there are no studies that have performed a non-inferiority analysis between treatments. METHODS Data from patients who were included in five randomised controlled trials from two different centres in Sweden were used. Outcomes at 1 year after ATR consisted of the patient-reported Achilles tendon Total Rupture Score (ATRS) and the functional heel-rise tests reported as the limb symmetry index (LSI). The non-inferiority statistical 10% margin was calculated as a reflection of a clinically acceptable disadvantage in ATRS and heel-rise outcome when comparing treatments. RESULTS A total of 422 patients (350 males and 72 females) aged between 18 and 71 years, with a mean age of 40.6 (standard deviation 8.6), were included. A total of 363 (86%) patients were treated surgically. The ATRS (difference (Δ) = - 0.253 [95% confidence interval (CI); - 5.673;5.785] p = 0.36) and LSI of heel-rise height (difference = 1.43 [95% CI; - 2.43;5.59] p = 0.81), total work (difference = 0.686 [95% CI; - 4.520;6.253] p = 0.67), concentric power (difference = 2.93 [95% CI; - 6.38;11.90] p = 0.063) and repetitions (difference = - 1.30 [95% CI; - 6.32;4.13] p = 0.24) resulted in non-inferiority within a Δ - 10% margin for patients treated non-surgically. CONCLUSION The non-surgical treatment of Achilles tendon ruptures is not inferior compared with that of surgery in terms of 1-year patient-reported and functional outcomes.

Abstract
Background: Immobilization of the ankle joint has been suggested as a key element in the
pathogenesis leading to deep vein thrombosis (DVT). Purpose: To investigate whether early controlled ankle motion (ECM) could reduce the
incidence of DVT compared with immobilization (IM) in the treatment of acute
Achilles tendon rupture. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: Patients aged 18 to 70 years were eligible for inclusion, and treatment was
nonoperative. The ECM group performed movements of the ankle 5 times a day
from weeks 3 to 8 after rupture. The control group was immobilized for 8
weeks. The outcome measure was DVT diagnosed with color Doppler ultrasound
for above- and below-knee DVT at 2 and 8 weeks. The Achilles tendon Total
Rupture Score, the heel-rise work test, and the Copenhagen Achilles
ultrasonographic Length Measurement were performed at 4-, 6-, and 12-month
follow-up. Results: A total of 189 patients were assessed for eligibility from February 2014 to
December 2016. Of these, 130 were randomized: 68 patients were allocated to
the ECM group and 62 to the IM group. All patients participated in follow-up
at 8 weeks assessing for DVT. In total, 62 (47.7%) patients were diagnosed
with DVT: 33 of 68 (48.5%) in the ECM group and 28 of 61 (46.8%) in the IM
group (P = .84). DVT did not affect treatment outcomes at
4, 6, and 12 months. D-dimer had low sensitivity (71%) for detecting
DVT. Conclusion: We found that 1 in 2 patients presented with DVT in nonoperative treatment of
acute Achilles tendon rupture. The ECM protocol revealed no benefit versus
IM in reducing the incidence of DVT. DVT did not influence functional and
patient-reported outcomes the first year after rupture. D-dimer seems an
inappropriate test for detection of DVT in patients with acute Achilles
tendon rupture. Registration: NCT02015364 (ClinicalTrials.gov

Abstract
Understanding the links between the tendon healing process, inflammatory mechanisms, and tendon homeostasis/pain after tissue damage is crucial in developing novel therapeutics for human tendon disorders. The inflammatory mechanisms that are operative in response to tendon injury are not fully understood, but it has been suggested that inflammation occurring in response to nerve signaling, i.e., neurogenic inflammation, has a pathogenic role. The mechanisms driving such neurogenic inflammation are presently not clear. However, it has recently been demonstrated that mast cells present within the injured tendon can express glutamate receptors, raising the possibility that mast cells may be sensitive to glutamate signaling and thereby modulate neurogenic inflammation following tissue injury. In this review, we discuss the role of mast cells in the communication with peripheral nerves, and their emerging role in tendon healing and inflammation after injury.

Aufwerber S, Heijne A, Edman G, Silbernagel KG, Ackermann PW. Does Early Functional Mobilization Affect Long-Term Outcomes After an Achilles Tendon Rupture? A Randomized Clinical Trial. Orthop J Sports Med 2020; 8:2325967120906522. [PMID: 32206673 PMCID: PMC7076581 DOI: 10.1177/2325967120906522] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Accepted: 12/03/2019] [Indexed: 12/15/2022] Open
Abstract
Background: Functional deficits and health-related impairments are common after an Achilles tendon rupture (ATR). Rehabilitation protocols vary greatly, and few studies have allowed loading in combination with ankle motion immediately after surgery (ie, early functional mobilization [EFM]). It is unclear whether EFM may counteract the negative impact of ankle immobilization after an ATR. Purpose: The primary aim of this study was to assess the efficacy of EFM compared with standard treatment (ie, 2 weeks of unloading in a plaster cast followed by 4 weeks of weightbearing in an orthosis) regarding patient-reported and functional outcomes in patients with an ATR after acute operative repair. The secondary aim was to explore whether the occurrence of deep venous thrombosis (DVT) during the 2 postoperative treatments affected outcomes. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: A total of 135 patients who underwent ATR repair, randomized to either EFM, including immediate postoperative loading and ankle motion, or standard treatment, were evaluated with functional tests and 5 self-administered outcome questionnaires at 6 and 12 months postoperatively. Results: At 6 months, the EFM group scored higher on the RAND 36-Item Health Survey (RAND-36) questionnaire subscales of general health and vitality (P < .05) compared with the control group. No significant differences between the groups were found on disease-specific questionnaires (Achilles tendon Total Rupture Score [ATRS] and Foot and Ankle Outcome Score [FAOS]). At 12 months, no significant differences on any of the patient-reported outcome measures or the functional heel-rise test were seen between the groups. The RAND-36 subscale of general health, however, exhibited higher values in the EFM group (82.6 ± 16.9) than the control group (77.1 ± 17.0) (P = .051) at 12 months after the injury. Patients sustaining DVT postoperatively had lower self-reported outcomes on the ATRS, FAOS, and RAND-36 questionnaires at 6 and 12 months compared with patients not having sustained DVT (all P < .05). Conclusion: This study demonstrated that an accelerated postoperative protocol with immediate loading and ankle motion resulted in better general health and vitality at 6 months. However, there were no differences between the groups in the recovery of heel-rise function. Future studies should focus on the means to reduce the risk of DVT to improve patient outcomes after ATR.

Understanding limitations in sport 1 year after an Achilles tendon rupture: a multicentre analysis of 285 patients. Knee Surg Sports Traumatol Arthrosc 2020; 28:233-244. [PMID: 31250056 DOI: 10.1007/s00167-019-05586-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2019] [Accepted: 06/18/2019] [Indexed: 10/26/2022]
Abstract
PURPOSE The purpose of this study was to determine patient-related and treatment-related predictors of superior and inferior function in sport and recreational activities 1 year after an Achilles tendon rupture. METHODS This study is based on a multicentre cohort from 4 previous randomised controlled trials. All the patients who had responded to the Foot and Ankle Outcome Score (FAOS) at the 1-year follow-up were included. All the patients had a clinically verified Achilles tendon rupture and patients who underwent surgery were treated within 96 h of the time of rupture. Patients were excluded in the event of a previous Achilles tendon rupture or the presence of other lifestyle diseases. The primary outcomes of the study were reported in the 20th and 80th percentiles of the FAOS subscale, function in sports and recreational activities. RESULTS A total of 285 (84% men) patients with an average age of 40.0 (SD 8.4) years were included. Smoking increased the odds of superior self-reported FAOS sport and recreation [OR 4.59 (95% CI 1.58-13.32), p = 0.005] compared with non-smoking, while being female [OR 0.38 (95% CI 0.16-0.93), p = 0.035] and every increment of one unit in BMI [OR 0.89 (95% CI 0.81-0.99), p = 0.029] reduced the odds. No variable was statistically significant when attempting to predict which patients report inferior FAOS sport and recreation. The recovery of symmetry in heel-rise tests had no effect on 1-year FAOS sport and recreation. Patient-reported outcomes had a good-to-excellent explanatory capacity of superior and inferior 1-year function in sport and recreational activities (AUC = 0.87-0.93). CONCLUSION BMI is a modifiable risk factor, which, when lowered, may be associated with less impairment in sports 1 year after an Achilles tendon rupture. Females appear to perceive more limitations than males. Unexpectedly, smokers experience less limitations in foot and ankle function. Patients who report no functional limitation in sport are characterised by an overall perception of adequate foot, ankle and Achilles function, despite not having recovered symmetry in the heel-rise test.

Abstract
PURPOSE Achilles tendon rupture (ATR) is a common injury. The knowledge of seasonal factors´ impact is incomplete, but may provide means for preventive approaches for Achilles tendon related morbidity. The aim of this study was to investigate seasonal variations in ATR incidence in relation to injury mechanism, adverse events including risk of re-rupture, and patient-reported outcome in adults in Stockholm, Sweden. METHODS In total, 349 patients with unilateral acute Achilles tendon rupture, prospectively treated with standardized surgical techniques, were retrospectively assessed. Date of injury was assigned to one of the four internationally defined meteorological seasons in the northern hemisphere. Injury mechanism and the rate of adverse events; deep venous thrombosis, infection and re-rupture in relation to per-operative complications. Patient-reported outcome at 1 year was assessed with the validated Achilles tendon Total Rupture Score. RESULTS ATR incidence was significantly highest during winter and spring, and lowest during summer (p < 0.05). The most common sporting activities associated with ATR were badminton, floorball and soccer (> 50%). The rate of soccer-related ATR was highest during summer (p < 0.05). Patients sustaining an ATR during summer, compared to other seasons, exhibited more per-operative complications (p < 0.05), a significantly higher risk of re-rupture (p < 0.05) and a lower rate of good outcome (n.s.). The risk of other adverse events after ATR did not differ between the seasons. CONCLUSION Winter and spring are the high risk seasons for sports-related ATR and the risk sports are badminton, soccer and floorball. The reason for the higher risk of re-rupture after ATR repair during summer should be further investigated. LEVEL OF EVIDENCE III.

Abstract
PURPOSE The hypothesis was that early functional mobilization would reduce the incidence of deep venous thrombosis (DVT) during leg immobilization after Achilles tendon rupture surgery. A secondary aim was to evaluate if the amount of weightbearing and daily steps influenced the risk of sustaining a DVT. METHODS One-hundred and fifty patients with Achilles tendon rupture repair were randomized to treatment with early functional mobilization, encouraging full weightbearing and ankle motion in orthosis, or treatment-as-usual, i.e., 2 weeks of unloading in plaster cast followed by 4 weeks weightbearing in orthosis. At 2 and 6 weeks postoperatively, all patients were screened for DVT using compression duplex ultrasound. During the first 2 weeks postoperatively, patient-reported loading, pain and step counts were assessed. RESULTS At 2 weeks, 28/96 (29%) of the patients in early functional mobilization group and 15/49 (31%) in the control group (n.s) had sustained a DVT. At 6 weeks, the DVT rate was 35/94 (37%) in the early functional mobilization and 14/49 (29%) in the control group (n.s). During the first postoperative week, the early functional mobilization group reported low loading and higher experience of pain vs. the control group (p = 0.001). Low patient-reported loading ≤ 50% (OR = 4.3; 95% CI 1.28-14.3) was found to be an independent risk factor for DVT, in addition to high BMI and higher age. CONCLUSIONS Early functional mobilization does not prevent the high incidence of DVT during leg immobilization in patients with Achilles tendon rupture as compared to treatment-as-usual. The low efficacy of early functional mobilization is mainly explained by postoperative pain and subsequent low weightbearing. To minimize the risk of DVT, patients should be encouraged to load at least 50% of body weight on the injured leg 1 week after surgery. LEVEL OF EVIDENCE Therapeutic, level 1.

Abstract
PURPOSE The aim of this study was to investigate whether patient subjective and functional outcomes after Achilles tendon rupture (ATR) are related to deep venous thrombosis (DVT) during leg immobilization. METHODS A cohort study with prospectively collected randomized data was conducted between 2010 and 2017. Two-hundred and fifty-one Patients with an Achilles tendon rupture (mean age = 41 ± 8), treated with uniform surgical techniques, were retrospectively analyzed. DVT incidence at 2 and 6 weeks was assessed using compression duplex ultrasound. At 12 months patient-reported outcomes were assessed using the Achilles tendon Total Rupture Score (ATRS), Foot- and Ankle Outcome Score (FAOS), Physical Activity Scale (PAS) and functional outcome with the calf-muscle endurance test. ANOVA analyses were used and adjusted for assumed confounding factors (patient age, sex, BMI and rehabilitation). RESULTS The total DVT incidence was 122 out of 251 (49%). Patients suffering a DVT exhibited significantly lower ATRS at 1 year compared to patients without DVT (mean 76 vs 83, 95% CI 71-79 vs 80-87; p < 0.01). Sixty-seven percent (95% CI 57-77%) of the patients devoid of DVT reported a good outcome (ATRS > 80) compared to 51% (95% CI 41-61%) of the patients sustaining a DVT (p < 0.05). Quality of life displayed significantly better outcome in the non-DVT versus DVT patients (mean = 75 (95% CI 71-79) vs. mean = 68 (95% CI 64-72); p < 0.05). A significant difference in total concentric work was observed between non-DVT and DVT patients (median = 1.9 kJ (IQR = 0.9 kJ) vs. median = 1.6 kJ (IQR = 1.0 kJ); p < 0.01). CONCLUSION Sustaining a DVT during leg immobilization significantly impairs patient-reported outcome at 1 year after surgical repair of ATR. LEVEL OF EVIDENCE III.

Abstract
Background: Early functional rehabilitation is frequently discussed in treating Achilles tendon rupture. A consistent definition of what constitutes early functional rehabilitation has not been established across the literature, despite studies supporting its efficacy. A standardized definition would be helpful to pool data across studies, allow for between-study comparisons, and ultimately work toward developing clinical guidelines. Purpose: To define early functional rehabilitation (including when it is initiated and what it entails) when used to treat Achilles tendon rupture and to identify outcome measures for evaluating the effect of treatment. Study Design: Systematic review; Level of evidence, 4. Methods: Ovid MEDLINE, EMBASE, PEDro, CINAHL, and Cochrane databases were searched for relevant studies. Eligibility criteria for selecting studies consisted of randomized controlled trials, cohort studies, and case series (≥10 participants) including weightbearing or exercise-based interventions within 8 weeks after Achilles tendon rupture. Results: A total of 174 studies published between 1979 and 2018 were included. Studies were rated a median (interquartile range [IQR]) of 17 (15-20) on the Downs & Black checklist and included 9098 participants. Early functional rehabilitation incorporated weightbearing (95%), range of motion (73%), and isometric/strengthening exercises (50%). Weightbearing was initiated within the first week, whereas exercise (eg, ankle range of motion, strengthening, whole-body conditioning) was initiated in the second week. Initiation of exercises varied based on whether treatment was nonsurgical (mean, 3.0 weeks; IQR, 2.0-4.0 weeks) or simple (mean, 2.0 weeks; IQR, 0.0-2.3 weeks) or augmented surgical repair (mean, 0.5 weeks; IQR, 0.0-2.8 weeks) (P = .017). Functional outcomes including ankle range of motion (n = 84) and strength (n = 76) were reported in 130 studies. Other outcome domains included patient-reported outcomes (n = 89), survey-based functional outcomes (n = 50), and tendon properties (n = 53). Conclusion: Early functional rehabilitation includes weightbearing and a variety of exercise-based interventions initiated within the first 2 weeks after acute Achilles tendon rupture/repair. Because early functional rehabilitation has lacked a standardized definition, interventions and outcome measures are highly variable, and pooling data across studies should be done with attention paid to what was included in the intervention and how treatment was assessed.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a well-known complication of Achilles tendon rupture (ATR) and carries a high risk of morbidity and mortality. Although routine thromboprophylaxis for patients with ATR is not recommended, sparse knowledge is available regarding risk factors associated with VTE in patients with ATR. PURPOSE To use Danish nationwide registers to identify incidence rates for symptomatic VTE and risk factors associated with increased risk of developing VTE in patients with ATR. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS By crosslinking nationwide registers, we identified all patients with diagnosed ATR in Denmark from 1997 to 2015. We stratified patients into 4 groups by age and treatment modality (ie, operative vs nonoperative treatment). The main outcome was VTE within 180 days. We calculated crude incidence rates and considered age, sex, year, comorbidities, and medications as risk factors for VTE in Poisson regression models. RESULTS We identified 28,546 patients with ATR, of whom 389 (1.36%) were hospitalized with VTE during the follow-up period: 278 due to deep vein thromboses and 138 due to pulmonary embolism. Incidence rates were highest during the first month and ranged from 4.6 to 14.6 events per 100 person-years. VTEs were most frequent among nonoperatively treated patients aged ≥50 years. In Poisson regression analyses, having had VTE beforehand was associated with an increased risk of VTE, as was male sex in the nonoperative treatment group aged ≥50 years; among women <50 years of age, hormonal contraceptives led to a 4- to 6-fold higher risk of VTE compared with patients in the same group without the equivalent risk factor. CONCLUSION In this nationwide cohort of patients with ATR, 1.36% developed symptomatic VTE during follow-up. Hormonal contraception, previous VTE, older age group, and male sex increased the risk of VTE. Taken together, the results of the present study suggest that focus on risk stratification and initiatives to prevent VTE might be warranted. A randomized controlled trial could answer this question.

Abstract
Objective Many trauma patients are at risk of pulmonary embolism due to unrecognized deep vein thrombosis (DVT). Restricted ankle dorsiflexion (AD) range of motion during leg immobilization is known to cause reduced venous blood flow. The aim of the present study was to assess whether AD at plaster cast removal is related to the incidence of DVT and to patient outcome. Design Prospective observational cohort study. Setting Level 1 Trauma Center. Patients A total of 124 patients (97 men, 27 women; mean age 40.3 years) with plaster cast leg immobilization after surgical repair of Achilles tendon rupture were assessed. Main outcome measures At 2 weeks postoperatively, assessments of AD and the incidence of DVT using compression duplex ultrasound were performed with observers blinded to patient grouping. Patients were dichotomized into 2 groups; poor or good AD, according to the mean AD, -7°. At 3- and 12 months patient-reported outcome was examined using validated questionnaires (ATRS and FAOS), and functional outcome using the heel-rise test. Results Patients with poor AD sustained 42% DVTs, while patients with good AD exhibited a DVT-rate of 23% (P = .036). Logistic regression analysis corroborated this finding (OR = 2.62, P = .036; 95% CI = 1.06-6.44). AD was not linked to any long-term functional or patient-reported outcome. Conclusions Reduced AD after plaster cast removal is associated with a higher risk of DVT. The results of this observational study warrant further prospective studies to confirm the effects of ankle dorsiflexion on the risk of developing venous thromboses.Level of evidence: II.

Abstract
BACKGROUND Acute Achilles tendon rupture (ATR) is a frequently disabling injury, which exhibits unclear variability in long-term functional and patient-reported outcomes. Biomarkers from early healing, which have been shown to be prognostic of long-term outcome would facilitate the development of improved treatment methods. HYPOTHESIS/PURPOSE The aim of this study was to assess essential metabolites pyruvate and its product lactate, as early biomarkers in relation to long-term functional- and patient-reported outcome after ATR. STUDY DESIGN Prospective cohort study. METHODS A total of 124 patients (103 men, 21 women; mean age 40 ± 7 years) with ATR, treated with uniform anesthetic and surgical technique, were prospectively assessed. At two weeks post-injury pyruvate and lactate concentrations were assessed in both the injured and uninjured limbs using microdialysis followed by enzymatic quantification. The ratios of the concentration in the injured versus uninjured limb of pyruvate (pyruvate-r) and lactate (lactate-r) were calculated as well as the lactate/pyruvate ratios (L/P-r). At 12 months, patient-reported outcome was examined using self-reported questionnaires; Achilles tendon Total Rupture Score (ATRS), Foot and Ankle Outcome Score (FAOS), and physical activity score. At 12 months, functional outcome was studied using the validated heel-rise test. RESULTS Elevated pyruvate-r, at two weeks, was significantly associated with total ATRS (R = 0.254, P = 0.028), less loss in physical activity (R = 0.241, P = 0.039), less experience of pain in FAOS (R = 0.275, P = 0.032), and a higher number of heel-rise repetitions on injured side (R = 0.230, P = 0.040) at 12 months. Increased lactate-r was related with less strength limitations in the calf (R = 0.283, P = 0.011), while the elevated lactate-pyruvate ratio, notably, was related to more limitations in walking on uneven surface (R = -0,243, P = 0.027). The findings were verified by multiple linear regression taking confounding factors into consideration. CONCLUSION This study established that the metabolite pyruvate is a good potential biomarker, prognostic of patient outcome at the one-year follow-up after ATR surgery. These novel findings suggest that local biomarkers could be developed at an early-stage screen for new ATR treatments.

Abstract
OBJECTIVES To evaluate the effects of vibration on Achilles' tendon microcirculation and characteristics following surgical repair of Achilles' tendon rupture. DESIGN Cohort study with historical controls. SETTING A university institute. PARTICIPANTS Participants (N=32), including 19 (16 men, 3 women; median [range] age: 43.0 [25.0-57.0] years) and 13 (10 men, 3 women; 44.00 [29.0-60.0] years) in the vibration (application to the ball of the foot, 30Hz, 2mm amplitude, 4kg pressure, and self-administration) and control groups, respectively, who underwent unilateral Achilles' tendon repairs were recruited. INTERVENTION A 4-week vibration intervention in the vibration group. MAIN OUTCOME MEASUREMENTS The tendon microcirculation was measured after the first session of vibration. The participants were evaluated repeatedly with bilateral follow-up measurements of tendon stiffness, 3 functional outcome tests, and a questionnaire survey. RESULTS Acute effects of the vibration were observed immediately after the 5-minute vibration (P≤.001). Lower total hemoglobin and oxygen saturation were respectively observed (P=.043) in the repaired legs 3 and 6 months postsurgery in the vibration group as compared with the control group. The vibration group also showed greater tendon stiffness, heel raising height and hopping distance 3 or 6 months postoperation in both the repaired and noninjured legs (all P<.05). The microcirculatory characteristics 2 months postoperation were correlated with the outcomes at 6 months postoperation. CONCLUSIONS Differences in microcirculatory characteristics and better rehabilitation outcomes were observed in the legs with an Achilles repair that underwent the early vibration intervention.

Abstract
Objective In this study, we compared the effects of intermittent pneumatic compression along with conventional treatment with cold-pack treatment along with conventional treatment on clinical outcomes in patients with knee osteoarthritis. Methods Eighty-nine patients with knee osteoarthritis participated in this study. One group received ultrasound, transcutaneous electrical nerve stimulation, electrical stimulation, exercise, and cold packs. The second group received ultrasound, transcutaneous electrical nerve stimulation, electrical stimulation, exercise, and intermittent pneumatic compression. Range of motion, muscle strength, knee swelling, pain intensity, and functional status were measured at baseline and 4th week. Results We found significant improvements in range of motion, muscle strength, pain intensity, and functional status after the treatment in both groups (p < 0.05). When comparing the effects of these two treatment programs, it was observed that the intermittent pneumatic compression treatment group had a better outcome in terms of knee swelling (p=0.028). Conclusions According to the results, we could report that intermittent pneumatic compression therapy in addition to conventional treatment has significant positive effects on clinical outcomes in patients with knee osteoarthritis. We could also report that intermittent pneumatic compression therapy along with conventional treatment is superior to cold-pack therapy along with conventional treatment in terms of knee swelling in patients with knee osteoarthritis. This trial is registered with NCT03806322.

Abstract
BACKGROUND Mechanical loading is essential for tendon healing and may explain variability in patient outcomes after Achilles tendon rupture (ATR) repair. However, there is no consensus regarding the optimal postoperative regimen, and the actual amount of loading during orthosis immobilization is unknown. PURPOSE The primary aim of this study was to assess the number of steps and the amount of loading in a weightbearing orthosis during the first 6 weeks after surgical ATR repair. A secondary purpose was to investigate if the amount of loading was correlated to fear of movement and/or experience of pain. STUDY DESIGN Case series; Level of evidence, 4. METHODS Thirty-four patients (mean ± SD age, 38.8 ± 8.7 years) with ATR repair were included. Early functional mobilization was allowed postoperatively in an orthosis with adjustable ankle range of motion. During the first postoperative 2 weeks, patient-reported loading and pain were assessed with a visual analog scale and step counts with a pedometer. At the 2- and 6-week follow-up, a mobile force sensor was used for measuring plantar force loading, and the Tampa Scale for Kinesiophobia was used to examine fear of movement. RESULTS Between the first and second weeks, there was a significant increase in the mean number of daily steps taken (from 2025 to 2753, P < .001) as well as an increase in self-reported loading (from 20% to 53%, P < .001). Patient self-reported loading was significantly associated with the plantar force measurement (rho = 0.719, P < .001). At 6 weeks, loading was 88.2% on the injured limb versus the uninjured limb. Fear of movement was not correlated with pedometer data, subjective loading, pain, or force data. Patients with less pain during activity, however, reported significantly higher subjective load and took more steps ( P < .05). CONCLUSION This is the first study to demonstrate the actual loading patterns during postoperative functional mobilization among patients with surgically repaired ATR. The quick improvements in loading magnitude and frequency observed may reflect improved tendon loading essential for healing. Pain, rather than fear of movement, was associated with the high variability in loading parameters. The data of this study may be used to improve ATR rehabilitation protocols for future studies.

Abstract
Background There is limited evidence regarding the patient-related factors that influence treatment outcomes after an acute Achilles tendon rupture. Purpose/Hypothesis The purpose of this study was to determine the predictors of functional and patient-reported outcomes 1 year after an acute Achilles tendon rupture using a multicenter cohort and to determine patient characteristics for reporting within the top and bottom 10% of the Achilles tendon Total Rupture Score (ATRS) and heel-rise height outcomes. The hypothesis was that older age, greater body mass index (BMI), and female sex would lead to inferior outcomes. Study Design Cohort study; Level of evidence, 2. Methods Patients were selected by combining 5 randomized controlled trials from 2 different centers in Sweden. Functional outcomes were assessed using validated heel-rise tests (height, number of repetitions, total work, and concentric power) for muscular endurance and strength, and the relationship between injured and uninjured legs was calculated as the limb symmetry index (LSI). Patient-reported outcomes were measured using the ATRS. All outcomes were collected at the 1-year follow-up. Independent predictors included were patient sex, smoking, BMI, age, and surgical versus nonsurgical treatment. Results Of the 391 included patients, 307 (79%) were treated surgically. The LSI of heel-rise height at the 1-year follow-up decreased by approximately 4% for every 10-year increment in age (beta, -3.94 [95% CI, -6.19 to -1.69]; P = .0006). In addition, every 10-year increment in age resulted in a 1.79-fold increase in the odds of being in the lowest 10% of the LSI of heel-rise height. Moreover, a nonsignificant superior LSI of heel-rise height was found in patients treated surgically compared with nonsurgical treatment (beta, -4.49 [95% CI, -9.14 to 0.16]; P = .058). No significant predictor was related to the ATRS. Smoking, patient sex, and BMI did not significantly affect the 1-year results for the LSI of the heel-rise tests. Conclusion Older age at the time of injury negatively affected heel-rise height 1 year after an Achilles tendon rupture. Irrespective of age, a nonsignificant relationship toward the superior recovery of heel-rise height was seen in patients treated surgically. None of the factors studied affected patient-reported outcomes.

Abstract
BACKGROUND Patient outcome after an acute Achilles tendon rupture (ATR) continues to be suboptimal and heterogeneous. Thus, prognostic factors are called for to optimize evidence-based ATR treatment protocols; however, the influence of delayed time from injury to surgery (TTS) on patient outcome after ATR remains largely unknown. PURPOSE To determine whether patient outcomes and adverse events after surgical repair of acute ATR are related to delayed TTS. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Two hundred twenty-eight patients with ATR who were treated with uniform anesthetic and surgical techniques, within 10 days after injury, were retrospectively assessed. TTS depended on availability of the operating theater, and neither surgeon nor patient could influence the TTS. Patients were assigned to 1 of 3 groups: short TTS (<48 hours), intermediate TTS (48-72 hours), and long TTS (>72 hours). Patient-reported outcome at 1 year was assessed with the validated Achilles tendon Total Rupture Score, with scores higher than 80 on a 0- to 100-point scale indicating an overall good outcome. The incidences of adverse events (perioperative and postoperative) and deep venous thrombosis were assessed. RESULTS Short TTS was significantly associated with increased rate of good outcome and reduced risk of adverse events. Seventy-one percent (95% CI, 60%-83%) of the patients with short TTS attained a good outcome compared with 44% (95% CI, 33%-56%) of the patients with long TTS ( P = .002), with the intermediate TTS group in between, 63% (95% CI, 47%-78%). The incidence of adverse events was significantly reduced among patients with short TTS, 1.4% (95% CI, 1%-4%) compared with those with intermediate TTS, 11% (95% CI, 2%-21%) ( P = .035) and those with long TTS, 14.8% (95% CI, 7%-23%) ( P = .003). The risk of sustaining a deep venous thrombosis was not statistically significantly different among the 3 groups ( P = .15). CONCLUSION Patients with acute ATR undergoing operation within 48 hours after injury had better outcomes and a lower number of adverse events compared with patients undergoing operation after 72 hours. These results align with evidence-based recommendations from other surgical disciplines and should be used as guidelines for optimizing ATR treatment protocols.

Abstract
PURPOSE AND HYPOTHESIS Adjuvant intermittent pneumatic compression (IPC) during leg immobilization following Achilles tendon rupture (ATR) has been shown to reduce the risk of deep venous thrombosis. The purpose of this study was to investigate whether IPC can also promote tendon healing. METHODS One hundred and fifty patients with surgical repair of acute ATR were post-operatively leg immobilized and prospectively randomized. Patients were allocated for 2 weeks of either adjuvant IPC treatment (n = 74) or treatment-as-usual (n = 74) in a plaster cast without IPC. The IPC group received 6 h daily bilateral calf IPC applied under an orthosis on the injured side. At 2 weeks post-operatively, tendon healing was assessed using microdialysis followed by enzymatic quantification of tendon callus production, procollagen type I (PINP) and type III (PIIINP) N-terminal propeptide, and total protein content. 14 IPC and 19 cast patients (control group) consented to undergo microdialysis. During weeks 3-6, all subjects were leg-immobilized in an orthosis without IPC. At 3 and 12 months, patient-reported outcome was assessed using reliable questionnaires (ATRS and EQ-5D). At 12 months, functional outcome was measured using the validated heel-rise test. RESULTS At 2 weeks post-rupture, the IPC-treated patients exhibited 69% higher levels of PINP in the ruptured Achilles tendon (AT) compared to the control group (p = 0.001). Interestingly, the IPC-treated contralateral, intact AT also demonstrated 49% higher concentrations of PINP compared to the non-treated intact AT of the plaster cast group (p = 0.002). There were no adverse events observed associated with IPC. At 3 and 12 months, no significant (n.s.) differences between the two treatments were observed using patient-reported and functional outcome measures. CONCLUSIONS Adjuvant IPC during limb immobilization in patients with ATR seems to effectively enhance the early healing response by upregulation of collagen type I synthesis, without any adverse effects. Whether prolonged IPC application during the whole immobilization period can also lead to improved long-term clinical healing response should be further investigated. The healing process during leg immobilization in patients with Achilles tendon rupture can be improved through adjuvant IPC therapy, which additionally prevents deep venous thrombosis.

Abstract
PURPOSE The relationship between the duration of operative time (DOT), healing response and patient outcome has not been previously investigated. An enhanced healing response related to DOT may potentiate repair processes, especially in hypovascular and sparsely metabolized musculoskeletal tissues such as tendons. This study aimed to investigate the association between DOT and the metabolic healing response, patient-reported outcome and the rate of post-operative complications after acute Achilles tendon injury. METHODS Observational cohort, cross-sectional study with observers blinded to patient grouping. A total of two-hundred and fifty-six prospectively randomized patients (210 men, 46 women; mean age 41 years) with an acute total Achilles tendon rupture all operated on with uniform anaesthetic and surgical technique were retrospectively assessed. At 2 weeks post-operatively, six metabolites were quantified using microdialysis. At 3, 6 and 12 months, patient-reported pain, walking ability and physical activity were examined using self-reported questionnaires, Achilles tendon total rupture score, foot and ankle outcome score and physical activity scale. At 12 months, functional outcome was assessed using the heel-rise test. Complications, such as deep venous thrombosis, infections and re-operations, were recorded throughout the study. RESULTS Patients who underwent longer DOT exhibited higher levels of glutamate (p = 0.026) and glycerol (p = 0.023) at 2 weeks. At the 1-year follow-up, longer DOT was associated with significantly less loss in physical activity (p = 0.003), less pain (p = 0.009), less walking limitations (p = 0.022) and better functional outcome (p = 0.014). DOT did not significantly correlate with the rate of adverse events, such as deep venous thrombosis, infections or re-ruptures. Higher glutamate levels were associated with less loss in physical activity (p = 0.017). All correlations were confirmed by multiple linear regressions taking confounding factors into consideration. CONCLUSION The results from this study suggest a previously unknown mechanism, increased metabolic response associated with longer DOT, which may improve patient outcome after Achilles tendon rupture surgery. Allowing for a higher amount of traumatized tissue, as reflected by up-regulation of glycerol in patients with longer DOT, may prove to be an important surgical tip for stimulation of repair of hypometabolic soft tissue injuries, such as Achilles tendon ruptures.

Abstract
INTRODUCTION Patients with plaster cast immobilization of the lower limb have an estimated symptomatic venous thromboembolism rate of 5.5%. However, there is currently no practical physical prophylaxis for deep-vein thrombosis (DVT). The objective of this study was to examine the effects of forced deep breathing on peak blood velocity in the superficial femoral vein (PBVFV), which is a surrogate measure of the efficacy of thromboprophylaxis against DVT, in patients with plaster cast immobilization of the lower limb. MATERIALS AND METHODS Nine young males and 18 elderly males were recruited. We immobilized the right lower limb of each subject with a plaster splint and measured PBVFV during forced deep breathing in supine and sitting positions. RESULTS In all subjects, PBVFV during forced deep breathing in both positions was significantly higher than at rest. There was no significant difference in the PBVFV change ratio for three breathing rates in the sitting position for the young subjects (15breaths/min: 415%, 5breaths/min: 475%, 3breaths/min: 483%), whereas that for the elderly subjects at 3breaths/min (449%) was significantly higher than that at 15breaths/min (284%). CONCLUSIONS Forced deep breathing significantly increased PBVFV in patients with plaster cast immobilization of the lower limb in both supine and sitting positions. Testing the efficacy and adherence in clinical contexts, and following up with the incidence rate of DVT in future studies, is necessary for the development of a new physical prophylaxis for DVT.

Abstract
RATIONALE The operative procedure for Achilles tendon rupture is relatively simple, but venous thromboembolism is serious complication with a high incidence after Achilles tendon rupture. However, the guideline for thromboprophylaxis in Achilles tendon rupture is unclear. PATIENT CONCERNS The patient was 32-year-old male and underwent Achilles tendon open repair surgery. He was healthy and there are no abnormal findings other than Achilles tendon rupture. At 3 weeks after operation, the episode of loss of consciousness with convulsive movement occurred. The next day, suddenly cardiac arrest occurred. DIAGNOSES Extensive pulmonary thromboembolism in both pulmonary arteries was identified in chest computed tomography and thrombus was also identified at the left popliteal vein on ultrasonography. INTERVENTION Anticoagulant therapy with heparin sodium was performed to manage the pulmonary thromboembolism. OUTCOMES Brain swelling after ischemic brain damage, acute kidney injury, and pneumonia gradually occurred and aggravated. His condition became worse and he died about 2 weeks after the cardiac arrest episode. LESSONS Although the incidence of venous thromboembolism in Achilles tendon rupture is higher than that in lower leg injury patients, guideline for thromboprophylaxis is unclear. We suggest that thromboprophylaxis for Achilles tendon rupture should be considered and appropriate guidelines should be established.

Abstract
Objectives The length of the tourniquet time during total knee arthroplasty (TKA) is related to the incidence of post-operative deep vein thrombosis (DVT). Our aim in this study was to investigate the effect of the early release of the tourniquet on the incidence of DVT in patients undergoing TKA. Methods A total of 200 patients who underwent TKA between November 2015 and November 2016 were prospectively enrolled. The tourniquet was inflated before surgery and released immediately after the introduction of the components (early release group). This group was compared with a retrospective cohort of 200 primary TKAs, in which the tourniquet was released after the dressings had been applied (late release group). The presence of a DVT was detected using bilateral lower limb ultrasonography. Peri-operative clinical and follow-up data were collected for analysis. Results The incidence of DVT in the early release group (9 of 196, 4.6%) was significantly lower compared with the late release group (24 of 200, 12%; odds ratio (OR) 0.35, 95% confidence interval (CI) 0.16 to 0.78, p = 0.008). The incidence of proximal DVT in the early release group (1 of 196 (0.5%)) was significantly lower than in the late release group (8 of 196, 4%; OR 0.12, 95% CI 0.02 to 0.99, p = 0.020). Although the mean intra-operative blood loss was higher in the early release group, the mean post-operative drainage, total blood loss, transfusion requirements and complications were not significantly different in the two groups. Conclusion In patients who undergo TKA, releasing the tourniquet early is associated with a decreased incidence of DVT, without increasing the rate of complications.

Abstract
UNLABELLED Venous thromboembolism (VTE) is a well-known and feared complication following foot and ankle surgery, as it is a source of morbidity and mortality in the perioperative phase. The most recent CHEST guidelines recommended against the use of chemoprophylaxis and the majority of the literature has found a low incidence of VTE following foot and ankle surgery. Some authors prefer screening patients for risk factors and recommend the use of chemoprophylaxis on a case-by-case basis. Interestingly, studies that found high incidence of VTE were unable to determine a statistically significant difference between the prophylaxis and placebo groups. Major limitations of retrospective reviews is they are only able to study symptomatic VTE because no routine screening is typically performed. In a survey study, up to 98% of foot and ankle surgeons responded that they use prophylaxis in high-risk patients. Despite evidence-based recommendations, a significant number of foot and ankle surgeons are routinely using some form of VTE prophylaxis without taking risk factors into account.

Abstract
BACKGROUND The changing demographics of Achilles tendon rupture (ATR) patients have not fully been investigated. However, there has been a general suspicion that this injury is occurring in an increasingly older population, in terms of mean age. The aim of this study was to objectively show an increase in age in Achilles tendon rupture patients over time. METHODS Published literature on Achilles tendon ruptures was searched for descriptive statistics on the demographics of patients in the studies, specifically mean and median age of Achilles tendon rupture patients, gender ratio, percentage of athletics-related injuries, percentage of smokers, and BMI. Linear regression analyses were performed to determine the trend of patient demographics over time. A Welch one-way ANOVA was carried out to identify any possible differences in data obtained from different types of studies. RESULTS The patient demographics from 142 studies were recorded, with all ATR injuries occurring between the years 1953 and 2014. There was no significant difference in the mean age data reported by varying study types, i.e. randomized controlled trial, cohort study, case series, etc. (P=0.182). There was a statistically significant rise in mean age of ATR patients over time (P<0.0005). There was also a statistically significant drop in percentage of male ATR patients (P=0.02). There is no significant trend for percentage of athletics-related injuries, smoking or BMI. CONCLUSION Since 1953 to present day, the mean age at which ATR occurs has been increasing by at least 0.721 years every five years. In the same time period, the percentage of female study patients with ATR injuries has also been increasing by at least 0.6% every five years. LEVEL OF EVIDENCE Level III; Retrospective cohort study.

Abstract
Patients with acute Achilles tendon rupture (ATR) display an extended healing process with varying clinical outcome. Poor microcirculatory blood flow has been suggested to be a significant factor for the healing process. However, whether microcirculation may predict healing outcome has been mostly unknown. Therefore, we investigated whether blood flow in the Achilles tendon may be associated with patient-reported and functional outcomes after ATR. In vivo laser-Doppler flowmetry was used to assess microvascular blood flow bilateral in the Achilles tendons, during post-occlusive reactive hyperemia, of nine patients with acute total ATR at 2 weeks post-operatively. At 3 months post-operatively, patient-reported outcome was assessed using Achilles tendon Total Rupture Score (ATRS). At 1 year a uniform outcome score, Achilles Combined Outcome Score (ACOS), was obtained by combining validated, independent, patient-reported (ATRS), and functional outcome (heel-rise test) measures. An improved combined patient-reported and functional outcome, ACOS, at 1 year was significantly correlated with higher maximum blood flow (r=.777, P=.040) in the injured limb. Furthermore, enhanced patient-reported outcome, ATRS, at 3 months, was associated with an elevated ratio of maximum to resting blood flow (r=.809, P=.015) in the uninjured limb. Blood flow in early tendon healing is associated with long-term patient-reported and functional outcomes after ATR. The microcirculatory blood flow of both the healing and contralateral Achilles tendon seems to determine the healing potential after injury.

Abstract
AIMS Patients with an acute Achilles tendon rupture (ATR) take a long time to heal, have a high incidence of deep vein thrombosis (DVT) and widely variable functional outcomes. This variation in outcome may be explained by a lack of knowledge of adverse factors, and a subsequent shortage of appropriate interventions. PATIENTS AND METHODS A total of 111 patients (95 men, 16 women; mean age 40.3, standard deviation 8.4) with an acute total ATR were prospectively assessed. At one year post-operatively a uniform outcome score, Achilles Combined Outcome Score (ACOS), was obtained by combining three validated, independent, outcome measures: Achilles tendon Total Rupture Score, heel-rise height test, and limb symmetry heel-rise height. Predictors of ACOS included treatment; gender; age; smoking; body mass index; time to surgery; physical activity level pre- and post-injury; symptoms; quality of life and incidence of DVT. RESULTS There were three independent variables that correlated significantly with the dichotomised outcome score (ACOS), while there was no correlation with other factors. An age of less than 40 years old was the strongest independent predictor of a good outcome one year after ATR (odds ratio (OR) 0.20, 95% confidence interval (CI) 0.08 to 0.51), followed by female gender (OR) 4.18, 95% CI 1.01 to 17.24). Notably, patients who did not have a DVT while immobilised post-operatively had a better outcome (OR 0.31, 95% CI 0.12 to 0.80). CONCLUSION Over the age of 40 years, male gender and having a DVT while immobilised are independent negative predictors of outcome in patients with an acute ATR.

Abstract
In recent years, the plantaris tendon has been implicated in the development of chronic painful mid-portion Achilles tendinopathy. In some cases, a thickened plantaris tendon is closely associated with the Achilles tendon, and surgical excision of the plantaris tendon has been reported to be curative in patients who have not derived benefit following conservative treatment and surgical interventions. The aim of this review is to outline the basic aspects of, and the recent research findings, related to the plantaris tendon, covering anatomical and clinical studies including those dealing with histology, imaging and treatment.

Abstract
PURPOSE Functional weight-bearing mobilization may improve repair of Achilles tendon rupture (ATR), but the underlying mechanisms and outcome were unknown. We hypothesized that functional weight-bearing mobilization by means of increased metabolism could improve both early and long-term healing. METHODS In this prospective randomized controlled trial, patients with acute ATR were randomized to either direct post-operative functional weight-bearing mobilization (n = 27) in an orthosis or to non-weight-bearing (n = 29) plaster cast immobilization. During the first two post-operative weeks, 15°-30° of plantar flexion was allowed and encouraged in the functional weight-bearing mobilization group. At 2 weeks, patients in the non-weight-bearing cast immobilization group received a stiff orthosis, while the functional weight-bearing mobilization group continued with increased range of motion. At 6 weeks, all patients discontinued immobilization. At 2 weeks, healing metabolites and markers of procollagen type I (PINP) and III (PIIINP) were examined using microdialysis. At 6 and 12 months, functional outcome using heel-rise test was assessed. RESULTS Healing tendons of both groups exhibited increased levels of metabolites glutamate, lactate, pyruvate, and of PIIINP (all p < 0.05). Patients in functional weight-bearing mobilization group demonstrated significantly higher concentrations of glutamate compared to the non-weight-bearing cast immobilization group (p = 0.045).The upregulated glutamate levels were significantly correlated with the concentrations of PINP (r = 0.5, p = 0.002) as well as with improved functional outcome at 6 months (r = 0.4; p = 0.014). Heel-rise tests at 6 and 12 months did not display any differences between the two groups. CONCLUSIONS Functional weight-bearing mobilization enhanced the early healing response of ATR. In addition, early ankle range of motion was improved without the risk of Achilles tendon elongation and without altering long-term functional outcome. The relationship between functional weight-bearing mobilization-induced upregulation of glutamate and enhanced healing suggests novel opportunities to optimize post-operative rehabilitation.

Abstract
UNLABELLED The efficient and effective function of the Achilles tendon is essential for normal gait and sporting performance. The optimal technique for the operative repair of the Achilles midsubstance rupture remains controversial. Suboptimal outcomes are common even after successful Achilles repair. Factors contributing to poor outcomes include a tenuous soft tissue envelope (leading to wound complications, peritendinous adhesions, and poor tendon healing,) as well as failure to maintain appropriate musculotendinous length, even after successful repair.We present a new technique using the InternalBrace (IB) and a modification of the Percutaneous Achilles Repair System (PARS; Arthrex Inc, Naples, FL), the Achilles Mid-Substance Speed Bridge Repair. This IB approach is knotless, respects the soft tissue envelope, and allows the appropriate musculotendinous length to be set intraoperatively. The IB principle enables direct fixation to bone allowing early mobilization while minimizing the risk of knot slippage, accelerating recovery, and allowing for restoration of normal function.

Abstract
Objective Patients who sustain acute Achilles tendon rupture (ATR) exhibit variable and mostly impaired long-term functional, and patient-reported outcomes. However, there exists a lack of early predictive markers of long-term outcomes to facilitate the development of improved treatment methods. The aim of this study was to assess markers of tendon callus production in patients with ATR in terms of outcome, pain, and fatigue. Study design and setting Prospective cohort study; level of evidence 2. Outpatient orthopaedic/sports medicine department. Patients A total of 65 patients (57 men, 8 women; mean age 41±7 years) with ATR were prospectively assessed. Assessments Markers of tendon callus production, procollagen type I N-terminal propeptide (PINP) and procollagen type III N-terminal propeptide (PIIINP), were assessed 2 weeks postoperatively using microdialysis followed by enzymatic quantification. Normalised procollagen levels (n-PINP and n-PIIINP) were calculated as the ratio of procollagen to total protein content. Pain and fatigue were assessed at 1 year using reliable questionnaires Achilles tendon Total Rupture Score (ATRS). Results Patients exhibited fatigue (77.6%) and pain (44.1%) to some extent. Higher levels of n-PINP (R=0.38, p=0.016) and n-PIIINP (R=0.33, p=0.046) were significantly associated with less pain in the limb. Increased concentrations of PINP (R=−0.47, p=0.002) and PIIINP (R=−0.37, p=0.024) were related to more self-reported fatigue in the leg. The results were corroborated by multiple linear regression analyses. Conclusions Assessment of procollagen markers in early tendon healing can predict long-term patient-reported outcomes after ATR. These novel findings suggest that procollagen markers could be used to facilitate the development of improved treatment methods in patients who sustain ATR.
