Int J Sports Phys Ther 2024; 19:670-680. [PMID: 38835984 PMCID: PMC11144663 DOI: 10.26603/001c.117549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 04/03/2024] [Indexed: 06/06/2024] Open
Abstract
Background While controversy remains as to the relative benefit of operative (OM) versus non-operative management (NOM) of Achilles tendon (AT) ruptures (ATR), few studies have examined the effect on high impact maneuvers such as jumping and hopping. Hypothesis/Purpose The purpose of this study was to determine if functional performance including strength, jumping, and hopping outcomes differed between OM and NOM of acute ATR. The secondary objective was to assess the degree of association between AT morphology and performance outcomes. Study Design Retrospective cohort with a single prospective evaluation. Methods All patients were treated at an institutional secondary care center. Eligible participants (n=12 OM; 12 NOM) who were treated with OM or NOM of ATR within three weeks of injury were evaluated a minimum 20 months following ATR. AT length, thickness and gastrocnemius muscle thickness were assessed with B-mode ultrasound. Isokinetic plantar flexor strength, hop tests and countermovement and drop jumps were completed. Two-way ANOVAS were completed on all tests with unilateral values, independent t-tests were used for bilateral outcomes, and linear regressions were completed to assess the relationship between normalized AT length and performance. Results Affected limb AT was elongated and thickened (p\<0.01), gastrocnemius was atrophied (p\< 0.01) and angle-specific plantar flexor torque was reduced at 120°/s when measured at 20° plantar flexion (p = 0.028). Single leg drop vertical jump was higher in OM (p = 0.015) with no difference for hop and jump tests. AT length was related to plantar flexor torque but had no relationship with hopping performance. Conclusions Hop test performance was maintained despite plantarflexion weakness, gastrocnemius atrophy, and AT elongation. This may be the result of compensatory movement patterns. AT length holds limited explanatory power in plantar flexor strength, although this relationship should be evaluated further. Level of Evidence Level III.

Abstract
Return to play (RTP) and functional outcomes are critical to treatment success for acute Achilles tendon rupture (AATR). This systematic review and meta-analysis explored treatment superiority essential in optimal treatment selection concerning individual patients and their expectations regarding RTP and functional outcomes. This study was in accordance with the preferred reporting items for systematic reviews and meta-analyses guidelines. The included studies were assessed regarding the level and quality of evidence. Fixed-effects models were employed for I2 < 25% and random-effects models for I2 ≥ 25%. The RTP rate meta-analysis of surgical vs conservative treatment revealed no significant difference. This was similar to the subgroup analysis of open repair and conservative treatment. The RTP rate and Achilles Tendon Total Rupture Score (ATRS) meta-analysis of open repair + earlier rehabilitation (ER) vs + later rehabilitation (LR) also revealed no significant differences. The mean time to RTP meta-analysis of open repair + ER vs + LR showed that open repair + ER was significantly favored (-4.19 weeks; p = .002). The ATRS meta-analysis of conservative treatment with ER vs with LR revealed no significant difference. This meta-analysis has revealed that the RTP rates following treatment of AATR are high. Therefore, the decision for surgical vs conservative treatment or open repair + ER vs + LR for AATR should not be selected based on the expectation of RTP. However, open repair + ER can be advocated over + LR for reduced mean time to RTP.

Abstract
Background There are many surgical techniques when repairing pectoralis major tears. However, there is no clear consensus on which repair technique is biomechanically superior. Our purpose was to perform a systematic review and meta-regression to evaluate the most biomechanically superior pectoralis major repair technique. Methods We performed a systematic review and meta-regression of six human cadaveric biomechanical studies evaluating fixation techniques for pectoralis major repairs. The primary outcome was the ultimate failure load. Covariates included cadaveric age, bone mineral density, implants, suture, and stitch method. Meta-regression accounted for differences in variables. Results Compared with Krackow/Bunnell stitch method, the modified Mason-Allen stitch demonstrated a decrease in ultimate failure load by 220.6 N (95% CI, -273.0 to -168.2; p = <0.001). No differences were found between Krackow/Bunnell and whipstitch. There was an increase in ultimate failure load when utilizing suture tape by 206.6 N (95% CI, 139.5-273.7, p < 0.001). Suture anchors had a decrease in ultimate failure load by 88.1 N (95% CI, -153.4 to -22.8, p = 0.008) when compared to transosseous sutures. No differences were found between transosseous sutures and unicortical buttons. Discussion We found the combination of suture tape in a whipstitch or Krackow/Bunnell stitch utilizing transosseous sutures or unicortical buttons is the most biomechanically superior construct for pectoralis major repairs.

Socioeconomic Status and Race Are Rarely Reported in Randomized Controlled Trials for Achilles Tendon Pathology in the Top 10 Orthopaedic Journals: A Systematic Review. FOOT & ANKLE ORTHOPAEDICS 2024; 9:24730114231225454. [PMID: 38288287 PMCID: PMC10823864 DOI: 10.1177/24730114231225454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/31/2024] Open
Abstract
Background Randomized controlled trials (RCTs) are crucial in comparative research, and a careful approach to randomization methodology helps minimize bias. However, confounding variables like socioeconomic status (SES) and race are often underreported in orthopaedic RCTs, potentially affecting the generalizability of results. This study aimed to analyze the reporting trends of SES and race in RCTs pertaining to Achilles tendon pathology, considering 4 decades of data from top-tier orthopaedic journals. Methods This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and used PubMed to search 10 high-impact factor orthopaedic journals for RCTs related to the management of Achilles tendon pathology. The search encompassed all articles from the inception of each journal until July 11, 2023. Data extraction included year of publication, study type, reporting of SES and race, primary study location, and intervention details. Results Of the 88 RCTs identified, 68 met the inclusion criteria. Based on decade of publication, 6 articles (8.8%) reported on SES, whereas only 2 articles (2.9%) reported on race. No RCTs reported SES in the pre-1999 period, but the frequency of reporting increased in subsequent decades. Meanwhile, all RCTs reporting race were published in the current decade (2020-2030), with a frequency of 20%. When considering the study location, RCTs conducted outside the United States were more likely to report SES compared with those within the USA. Conclusion This review revealed a concerning underreporting of SES and race in Achilles tendon pathology RCTs. The reporting percentage remains low for both SES and race, indicating a need for comprehensive reporting practices in orthopaedic research. Understanding the impact of SES and race on treatment outcomes is critical for informed clinical decision making and ensuring equitable patient care. Future studies should prioritize the inclusion of these variables to enhance the generalizability and validity of RCT results.

Abstract
PURPOSE Acute Achilles tendon tears in young active individuals are often treated surgically with prolonged rehabilitation, with the leg initially immobilized in plantar flexion in serial non-weight bearing casts and gradually progressing to full weight bearing. This study aimed to evaluate the safety of an early functional unsupervised rehabilitation protocol. METHODS The medical records of 25 patients treated with open repair were available for follow-up. In 10 patients, an early functional unsupervised rehabilitation protocol was used with a removable cast, active range of motion exercises of the ankle from the first postoperative day, and full weight bearing in a walking boot with the foot plantigrade after the second week. Another 15 patients who followed the classic rehabilitation protocol were used as controls. The patients were evaluated with the Victorian Institute of Sports Assessment-Achilles (VISA-A) and an ultrasound examination-based score. A Wilcoxon test was used to compare the scores between the groups. RESULTS The mean VISA-A score was 90.1 (SD = 9.87) for the early functional rehabilitation protocol group, while it was 83.8 (SD = 17.06, p = 0.624) for the control group. The mean ultrasound score was 7.75 (SD = 1.71) for the early functional rehabilitation protocol group, while it was 7.60 (SD = 3.05, p = 0.414) for the control group. There were no intra- or early postoperative complications in the groups, and all patients were satisfied with the results of their operation. CONCLUSIONS An early unsupervised functional rehabilitation protocol after open Achilles repair may allow for safe early mobilization and minimize the need for physiotherapy. The small number of participants is a limitation of this study, and further evaluation with more patients is necessary to document the efficacy.

Portable device for measuring isometric plantar-flexion force after open Achilles repair: Retrospective cohort of 30 recreational athletes with one-year minimum follow-up. Orthop Traumatol Surg Res 2023:103791. [PMID: 38072309 DOI: 10.1016/j.otsr.2023.103791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Revised: 02/25/2023] [Accepted: 08/21/2023] [Indexed: 12/17/2023]
Abstract
BACKGROUND Plantar flexion force in recreational athletes after repair of Achilles tendon tears has rarely been reported, due to the lack of a widely available and fast measurement method. Knowledge of this parameter would allow optimisation of muscular and sports recovery. The main objective of this study was to measure the isometric force of the triceps surae at least 1 year after unilateral Achilles-tendon repair, comparatively to the unaffected side, using a portable device. The secondary objectives were to compare Achilles tendon and calf-muscle trophicity, dorsiflexion, and the single-leg heel-rise test versus the normal side and to assess functional scores at last follow-up. HYPOTHESES (i) Plantar flexion force does not differ significantly between the operated and contralateral sides. (ii) Calf-muscle trophicity, dorsiflexion, and the single-leg heel-rise test do not differ significantly between the operated and contralateral sides. PATIENTS AND METHODS This single-centre retrospective study included patients aged 18 to 65 years with a history of open repair of an acute unilateral Achilles tear at least 1 year earlier. Plantar flexion force, calf-muscle trophicity, dorsiflexion, and the heel-to-floor distance were measured on both sides and compared. The ATRS, VISA-A score, and EFAS score were determined. All complications were recorded. RESULTS The study included 30 patients with a mean follow-up of 20.3 months (range, 12-28 months). The operated side had significantly lower values for isometric triceps surae force, calf circumference, and heel-to-floor distance compared to the contralateral side (p<0.0001). Tendon width was significantly greater on the operated side (p<0.0001). Dorsiflexion did not differ significantly between sides (p=0.106). Mean functional score values were 91.5±6 for the ATRS (maximum, 100), 85±12 for the VISA-A score (maximum, 100), and 19.5±4 for the EFAS score (maximum, 24). DISCUSSION Isometric triceps-surae force measured using a portable device at least 1 year after open surgical Achilles-tendon repair was significantly decreased compared to the contralateral side. Calf circumference and heel-to-floor distance were also significantly lower. These data indicate a need for improved monitoring of triceps surae recovery to optimise rehabilitation and sports resumption. LEVEL OF EVIDENCE IV, retrospective comparative cohort study.

Abstract
Background Patient outcome after acute Achilles tendon rupture (ATR) varies and is difficult to predict. Whether early variations in healing, visualized with ultrasonography, can predict long-term patient outcome is unclear. Purpose To (1) examine the associations of Achilles tendon cross-sectional area (CSA) and elongation (TE) during healing of ATR repair with patient outcomes at 12 months postoperatively and (2) investigate the predictive or diagnostic capacity of the morphological biomarkers. Study Design Cohort study; Level of evidence, 2. Methods This study was based on previously collected data from 86 patients who underwent acute standardized ATR repair between 2013 and 2018 and who were included in a prior randomized trial investigating early functional mobilization (EFM). In the EFM group, loading was allowed immediately after surgery, while in the comparison group, loading was allowed first at 2 weeks postoperatively. Achilles tendon CSA and length were measured with ultrasound at 6 weeks, 6 months, and 12 months postoperatively. CSA ratio and absolute difference in the length of the healthy and injured tendons were calculated. Patient-reported outcome was registered with the validated Achilles tendon Total Rupture Score and functional outcome with the heel-rise endurance test at 12 months postoperatively. The limb symmetry index (LSI) was calculated for maximum heel-rise height (HRHmax) and total concentric work. Multiple linear regression adjusted for age was used, and the area under the receiver operating characteristic curve (AUC) was calculated to evaluate predictive capacity. Results A larger CSA ratio at 6 weeks was associated with higher LSI HRHmax at 12 months (R2, 0.35; P < .001) and exhibited good predictive capacity (AUC, 0.82). More TE at 12 months was associated with lower LSI total concentric work at 12 months (R2, 0.21; P = .001) and exhibited acceptable predictive capacity (AUC, 0.71). Conclusion Greater Achilles tendon CSA seen on ultrasound 6 weeks after surgical repair had good clinical prediction for long-term functional outcome. TE at 12 months was predictive of inferior functional outcome. Registration NCT02318472 (ClinicalTrials.gov identifier).

Case study: The influence of Achilles tendon rupture on knee joint stress during counter-movement jump - Combining musculoskeletal modeling and finite element analysis. Heliyon 2023; 9:e18410. [PMID: 37560628 PMCID: PMC10407047 DOI: 10.1016/j.heliyon.2023.e18410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 07/15/2023] [Accepted: 07/17/2023] [Indexed: 08/11/2023] Open
Abstract
BACKGROUND Presently, the current research concerning Achilles tendon rupture repair (ATR) is predominantly centered on the ankle joint, with a paucity of evidence regarding its impact on the knee joint. ATR has the potential to significantly impede athletic performance and increase tibiofemoral contact forces in athletes. The purpose of this study was to prognosticate the distribution of stress within the knee joint during a countermovement jump through the use of a simulation method that amalgamated a musculoskeletal model of a patient who underwent Achilles tendon rupture repair with a finite element model of the knee joint. METHODS A male elite badminton player who had suffered an acute Achilles tendon rupture in his right leg one year prior was selected as our study subject. In order to analyze his biomechanical data, we employed both the OpenSim musculoskeletal model and finite element model to compute various parameters such as joint angles, joint moments, joint contact forces, and the distribution of knee joint stress. RESULTS During the jumping phase, a significantly lower knee extension angle (p < 0.001), ankle dorsiflexion angle (p = 0.002), peak vertical ground reaction force (p < 0.001), and peak tibiofemoral contact force (p = 0.009) were observed on the injured side than on the uninjured side. During the landing phase, the ankle range of motion (ROM) was significantly lower on the injured side than on the uninjured side (p = 0.009), and higher peak vertical ground reaction forces were observed (p = 0.012). Additionally, it is logical that an injured person will put higher load on the uninjured limb, but the finite element analysis indicated that the stresses on the injured side of medial meniscus and medial cartilage were significantly greater than the uninjured side. CONCLUSIONS An Achilles tendon rupture can limit ankle range of motion and lead to greater joint stress on the affected area during countermovement jumps, especially during the landing phase. This increased joint stress may also transfer more stress to the soft tissues of the medial knee, thereby increasing the risk of knee injury. It is worth noting that this study only involves the average knee flexion angle and load after ATR in one athlete. Caution should be exercised when applying the conclusions, and in the future, more participants should be recruited to establish personalized knee finite element models to validate the results.

Abstract
BACKGROUND Patient Reported Outcome Measures (PROMs) are utilized in level 1 randomized controlled trials involving Achilles tendon ruptures. However, the characteristics of these PROMs and current practices has not yet been reported. We hypothesize that there will be heterogeneous PROM usage in this context. METHODS A PubMed and Embase systematic review was performed including all dates up to July 27th, 2022, assessing Achilles tendon ruptures in level 1 studies using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines where applicable. Inclusion criteria were all randomized controlled clinical studies involving Achilles tendon injuries. Studies that: (1) were not level 1 evidence (including editorial, commentary, review, or technique articles), (2) omitted outcome data or PROMs, (3) included injuries aside from Achilles tendon ruptures, (4) involved non-human or cadaveric subjects, (5) were not written in English, and (6) were duplicates were excluded. Demographics and outcome measures were assessed in the studies included for final review. RESULTS Out of 18,980 initial results, 46 studies were included for final review. The average number of patients per study was 65.5. Mean follow up was 25 months. The most common study design involved comparing two different rehabilitation interventions (48 %). Twenty different outcome measures were reported including the Achilles tendon rupture score (ATRS) (48 %), followed by the American Orthopedic Foot and Ankle score Ankle-Hindfoot score (AOFAS-AH) (46 %), the Leppilahti score (20 %), and the RAND-36/Short Form (SF) - 36/SF-12 scores (20 %). An average of 1.4 measures were reported per study. CONCLUSION Significant heterogeneity exists in PROM usage among level 1 studies involving Achilles tendon ruptures, which prevents meaningful interpretation of these data across multiple studies. We advocate for usage of at least the disease-specific Achilles Tendon Rupture score and a global, quality of life (QOL) survey such as the SF-36/12/RAND-36. Future literature should provide more evidence-based guidelines for PROM usage in this context. LEVEL OF EVIDENCE Level IV; Systematic Review.

Abstract
BACKGROUND To explore and compare the clinical outcomes in patients undergoing primary repair versus augmented repair with a gastrocnemius turn-down flap for acute Achilles tendon rupture. METHODS From 2012 to 2018, the clinical data of 113 patients with acute Achilles tendon rupture who were treated with primary repair or augmented repair with a gastrocnemius turn-down flap by the same surgeon were retrospectively reviewed. The patients' preoperative and postoperative scores on the visual analog scale (VAS), American Orthopaedic Foot and Ankle Society Ankle⁃Hindfoot (AOFAS) score, the Victorian Institute of Sport Assessment⁃Achilles (VISA-A), the Achilles tendon total rupture score (ATRS), and the Tegner Activity Scale were examined and compared. The postoperative calf circumference was measured. A Biodex isokinetic dynamometer was used to evaluate the plantarflexion strength on both sides. The time to return to life and exercise as well as the strength deficits in both groups were recorded. Finally, the correlation analyses between patient characteristics and treatment details with clinical outcomes were conducted. RESULTS In total, 68 patients were included and completed the follow-up. The 42 and 26 patients who were treated with primary repair and augmented repair were assigned to group A and B, respectively. No serious postoperative complications were reported. No significant between-group differences in any outcomes were observed. It was found that female sex was correlated with poorer VISA-A score (P = 0.009), complete seal of paratenon was correlated with higher AOFAS score (P = 0.031), and short leg cast was correlated with higher ATRS score (P = 0.006). CONCLUSIONS Augmented repair with a gastrocnemius turn-down flap provided no advantage over primary repair for the treatment of acute Achilles tendon rupture. After surgical treatment, females tended to had poorer outcomes, while complete seal of paratenon and short leg cast contributed to better results. LEVEL OF EVIDENCE Cohort study; Level of evidence, 3.

The Acute Achilles Tendon Rupture: An Evidence-Based Approach from the Diagnosis to the Treatment. Medicina (B Aires) 2022; 58:medicina58091195. [PMID: 36143872 PMCID: PMC9500605 DOI: 10.3390/medicina58091195] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 08/26/2022] [Accepted: 08/29/2022] [Indexed: 11/16/2022] Open
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
Persistent muscle weakness, tendon elongation, and incomplete return to preinjury level are frequent sequelae after acute Achilles tendon rupture, and evidence-based knowledge of how to best rehabilitate the injury is largely absent in the literature. The objective of this review is to illuminate and discuss to what extent an Achilles tendon rupture affects muscle, tendon, and function when assessed with the Achilles tendon total rupture score (ATRS), muscle strength, muscle cross-sectional area, tendon length, and the heel-rise test. The patient-reported outcome measures (PROM) data in the literature suggest that the recovery takes longer than 6 months (ATRS, 70 out of 100), that one-year postinjury, the ATRS only reaches 82, and that this does not appear to noticeably improve thereafter. Loss of muscle mass, strength, and function can in some cases be permanent. Over the first 6 months postinjury, the tendon undergoes elongation, which appears to be negatively correlated to heel-rise function. More recently, there has been some interest in how muscle length and excursion is related to the reduced function. The available literature indicates that further research is highly warranted and that efforts to restore normal tendon length may improve the likelihood of returning to preinjury level after an Achilles tendon rupture.

Functional outcome of early weight bearing for acute Achilles tendon rupture treated conservatively in a weight-bearing orthosis. Foot Ankle Surg 2022; 28:595-602. [PMID: 34301483 DOI: 10.1016/j.fas.2021.06.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Revised: 06/07/2021] [Accepted: 06/28/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND The optimal management for Achilles tendon (AT) ruptures is controversial and still continues to encourage debate. Conventionally, operative repair was favoured secondary to its lower rates of re-rupture, however in more recent years, we have seen promising results and a reduction in complications with conservative management. One reason for this improvement may be due to the introduction of a functional weight-bearing orthosis, however, results for complete AT ruptures is still unclear. This study aims to evaluate the functional outcomes of early weight bearing in a functional orthosis for conservatively managed, complete AT ruptures. METHODOLOGY This study was done at East Kent Hospital University Foundation Trust in between 2019-2020. In this prospective study, we have analysed data from 41 patients with US diagnosed compete AT ruptures, with a gap less than 5 cm. Every patient was treated in a functional weight-bearing orthosis (VACOped®) for 8 weeks with early weight-bearing following a specific treatment protocol, followed by rehabilitation with a trained physiotherapist. All patients received a final follow-up at 1 year post injury, where we recorded the following functional outcome measurements on each leg: calf girth, single leg heel raise height, single leg heel raise repetitions and the ATRS score. RESULT Our study population was predominantly male with an average age of 50 (range 22-79). The majority of the cohort were physically active, with more than 75% involved in a form of sporting activity pre-injury and 15% involved in higher level activity and competitive sport. The mean ATRS score was 82.1, with a re-rupture rate of only 2%. The average calf bulk difference was 1.6 cm, average heel raise height difference was 1.8 cm and a heel raise repetition difference of 6. There was a statistically significant correlation between ATRS score and calf muscle girth (p = 0.02). However, there was no significant correlation between ATRS score and heel raise height or single heel raise repetitions. CONCLUSION Early weight-bearing in a functional orthosis provides excellent functional outcomes for conservatively managed, complete AT ruptures, and is associated with very low re-rupture rates. However, a multidisciplinary approach with a guided rehabilitation programme is essential for optimising functional outcome.

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
Injuries to the Achilles tendon are a challenge to the foot and ankle surgeon. In recent years, research has led to a relative change in the way that many surgeons view acute Achilles tendon rupture. In an effort to fully evaluate these trends, as well as to evaluate all aspects of care for acute Achilles tendon rupture, the American College of Foot and Ankle Surgeons convened a panel of experts to create a clinical consensus statement to address selected aspects of care of the acute Achilles tendon injury.

Abstract
Background. The purpose of this study is to evaluate the treatment considerations and surgical techniques utilized by fellowship-trained orthopaedic sports medicine and foot and ankle specialists in the management of Achilles tendon ruptures. Methods. A blinded electronic survey was distributed to 2062 fellowship-trained sports medicine and 1319 fellowship-trained foot and ankle orthopaedic surgeons. The total number of acute Achilles tendon ruptures managed per year, patient-specific factors associated with surgical decision making and surgical techniques were evaluated. Results. Of the 3381 surveys distributed, 524 responses were included for analysis. Only 9% of respondents manage more than 20 acute Achilles tendon ruptures per year with the majority (75%) managing less than 10 per year. Operative management is the treatment of choice for 76% of total respondents with only 8% managing acute ruptures nonoperatively. Activity level and patient age were the single most important factors for 60.8% and 29.3% of surgeons, respectively, with regard to operative versus nonoperative decision making. Socioeconomic status and workers compensation were the least important patient factors. Conclusion. Surgical repair in the young and active patient is the preferred treatment for the majority of fellowship-trained subspecialists who most commonly encounter this pathology.Levels of Evidence: Therapeutic, Level V: Consensus of Expert Analysis.

Abstract
The Achilles tendon is the thickest, strongest and largest tendon in the human body, but despite its size and tensile strength, it frequently gets injured. Achilles tendon ruptures (ATRs) mainly occur during sports activities, and their incidence has increased over the last few decades. Achilles tendon tears necessitate a prolonged recovery time, sometimes leaving long-term functional limitations. Treatment options include conservative treatment and surgical repair. There is no consensus on which is the best treatment for ATRs, and their management is still controversial. Limited scientific evidence is available for optimized rehabilitation regimen and on the course of recovery after ATRs. Furthermore, there are no universally accepted outcomes regarding the return to play (RTP) process. Therefore, the aim of this narrative review is to give an insight into the mechanism of injuries of an ATR, related principles of rehabilitation, and RTP.

Abstract
In this report, we describe a rare case of open rerupture of an Achilles tendon following primary surgical repair. The rerupture occurred 12 weeks postoperatively and was associated with a transverse open wound perpendicular to the original surgical incision. This complication was successfully managed utilizing the preexisting transverse wound and a minimally invasive repair technique, minimizing further risk to the soft tissues overlying the tendon. This rare complication has only been described a few times in the literature and is likely associated with adhesions between the tendon repair and the subcutaneous tissues.

Abstract
PURPOSE Rupture of the Achilles tendon (AT) is a common injury. Strength deficits may persist over the long term, possibly owing to elongation of the tendon or inferior mechanical properties. This study aimed to provide a systematic review of the literature on the prevalence and consequences of tendon elongation in patients after acute AT rupture treatment. It was hypothesized that an elongated tendon would be associated with a worse clinical outcome. METHODS The databases for MEDLINE, CENTRAL and Web of Science were searched. Clinical studies related to AT rupture reporting tendon elongation and clinical or functional outcomes, with a minimum follow-up of 6 months, were eligible for inclusion. Only studies testing for statistical correlations (SCs) between AT elongation and other outcomes were eligible, with the exception of biomechanical studies in which statistically significant AT elongation was found to be a generalized finding in the study group. For these studies to be eligible, the study group had to be compared with a healthy control group, or the injured limb compared with the uninjured limb, regarding biomechanical parameters. RESULTS Twenty-eight papers were selected for inclusion. Mean AT elongation measured with imaging techniques ranged from 0.15 to 3.1 cm (n = 17). Ten studies investigated SCs with Patient Reported Outcome Measures (PROMs), in which two found SCs with tendon elongation. Five studies reported strength and power evaluations and their correlation with AT elongation, with two having found SCs between decreased strength and tendon elongation. In ten studies reporting data on biomechanical tests, nine found influence of tendon elongation. In this group, four out of five studies found SCs with biomechanical parameters. CONCLUSION Fair evidence of the influence of tendon elongation in biomechanical parameters was found. In a general population, evidence of a detrimental effect of tendon elongation on PROMs or functional strength at follow-up was not found in this review. LEVEL OF EVIDENCE Level IV.

Abstract
Heel-rises are commonly used in the rehabilitation of individuals following Achilles tendon rupture, however, the impact of tendon elongation on triceps surae activation in seated versus standing positions has not been investigated. The purpose of this study was to investigate changes in triceps surae activation during seated compared to standing heel-rises in individuals with Achilles tendon rupture and its relationship to tendon elongation. Ten individuals with a history of Achilles tendon rupture were included in this study. Muscle activity using electromyography was examined during a heel-rise task in seated (unilateral) and standing (bilateral) positions. Soleus activity was not significantly different between sitting and standing on both the ruptured and uninjured side. On the ruptured, side there were no differences in medial or lateral gastrocnemius activity between sitting and standing; however, on the uninjured side medial and lateral gastrocnemius activity was lower in sitting compared to standing. The results of this study suggest that neuromuscular changes in triceps surae activation occur following Achilles tendon rupture. The seated heel-rise position can be used to strengthen all muscles of the triceps surae and is useful when the patient is unable to perform a standing heel-rise.

Abstract
BACKGROUND In the presence of a large gap where end-to-end repair of the torn Achilles tendon is difficult and V-Y advancement would likely be insufficient, augmentation is sometimes required. At our institute we have used primarily the hamstring autograft augmentation technique for the past two decades. The aim of this study was to analyze the complications after surgical treatment of Achilles tendon rupture with semitendinous tendon augmentation. METHODS We retrospectively analyzed 58 consecutive patients treated with semitendinous tendon autograft augmentation at the Helsinki University Hospital between January 1, 2006, and January 1, 2016. RESULTS During the study period, 58 patients were operated on by six different surgeons. Of 14 observed complications (24%), seven were major and seven were minor. Most of the complications were infections (n = 10 [71%]) The infections were noted within a mean of 62 days postoperatively (range, 22-180 days). Seven patients with a complication underwent repeated operation because of skin edge necrosis and deep infection (five patients), hematoma formation (one patient), and a repeated rupture (one patient). CONCLUSIONS In light of the experience we have had with autologous semitendinous tendon graft augmentation, we cannot recommend this technique, and, hence, we should abandon reconstruction of Achilles tendon ruptures with autologous semitendinous tendon grafts at our institute. Instead, other augmentation techniques, such as flexor hallucis longus tendon transfer, should be used.

Abstract
BACKGROUND Little data exist regarding the adverse effects of Achilles tendon (AT) elongation after rupture repair on plantarflexion strength. This study aimed to investigate the effect of AT elongation measured using AT resting angle (ATRA) on the plantarflexion strength in patients with surgically treated acute AT rupture. METHODS A retrospective chart review was performed on 40 patients (15 female and 25 female) who underwent open operative repair due to an acute AT rupture. At the final follow-up, AT elongation was assessed using ATRA. Plantarflexion strength (peak torques and angle-specific torques) was measured using an isokinetic dynamometer. All variables were obtained from the operated and unoperated contralateral ankles of the patients. RESULTS The mean ATRA was greater in the operated ankles (mean, 57 degrees; range, 39-71 degrees) compared with the unoperated ones (mean, 52 degrees; range, 36-66 degrees; P = .009). Except the plantarflexion torque at 20 degrees of plantarflexion (P = .246), all the other angle-specific torques were lower in the operated ankles (P < .05). Peak flexion torque at 30 degrees/s was lower in the operated ankle (P = .002). A negative correlation was found between operated/unoperated (O/N) ATRA and O/N plantarflexion torque ratios at 0 degrees (r = -0.404; P = .01), 10 degrees (r = -0.399; P= .011), and 20 degrees (r = -0.387; P = .014). CONCLUSION Postoperative AT elongation measured using ATRA may have a deleterious effect on the plantarflexion strength in patients with surgically treated acute AT rupture.

Abstract
PURPOSE Achilles tendon rupture leads to long-term plantar flexor deficits, but some patients recover functional performance better than others. Early indicators of tendon healing could be helpful in establishing patient prognosis and making individualized decisions regarding rehabilitation progression. The purpose of this study was to investigate relationships between early tendon morphology and mechanical properties to long-term heel-rise and jumping function in individuals after Achilles tendon rupture. METHODS Individuals after Achilles tendon rupture were assessed at 4, 8, 12, 24, and 52 weeks post-injury. Tendon cross-sectional area, length, and mechanical properties were measured using ultrasound. Heel-rise and jump tests were performed at 24 and 52 weeks. Correlation and regression analysis were used to identify relationships between tendon structural variables in the first 12 weeks to functional outcomes at 52 weeks, and determine whether the addition of tendon structural characteristics at 24 weeks strengthened relationships between functional performance at 24 and 52 weeks. Functional outcomes of individuals with < 3 cm of elongation were compared to those with > 3 cm of elongation using a Mann-Whitney U test. RESULTS Twenty-two participants [mean (SD) age = 40 (11) years, 17 male] were included. Tendon cross-sectional area at 12 weeks was the strongest predictor of heel-rise height (R2 = 0.280, p = 0.014) and work symmetry (R2 = 0.316, p = 0.008) at 52 weeks. Jumping performance at 52 weeks was not significantly related to any of the tendon structural measures in the first 12 weeks. Performance of all functional tasks at 24 weeks was positively related to performance on the same task at 52 weeks (r = 0.456-0.708, p < 0.05). The addition of tendon cross-sectional area improved the model for height LSI (R2 = 0.519, p = 0.001). Tendon elongation > 3 cm significantly reduced jumping symmetry (p < 0.05). CONCLUSION Tendon cross-sectional area and excessive elongation related to plantar flexor performance on functional testing after Achilles tendon rupture. Once an individual is able to perform function-based testing, tendon structural measures may inform long-term prognosis. Ultrasound-based measures of tendon structure early in recovery seem to relate to later performance on functional testing. Clinically, assessing tendon structure has the potential to be used as a biomarker of tendon healing early in recovery and better predict patients at risk of negative functional outcome.

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 The common calcanean tendon (Achilles tendon) is the strongest and largest tendon and is one of the most commonly affected by spontaneous rupture. Different suture techniques are used to repair the tendon rupture. We compare the biomechanical properties of three different modalities of suture pattern in a mechanical experiment in rabbits with the purpose of evaluating the use of polypropylene mesh augmentation for Achilles tendon repair to find out the best surgical option. Methods The study tests single cycle to failure tensile strength characteristics of three different combinations of the 3-loop pulley (3-LP) suture technique with polypropylene mesh, and statistically compares the biomechanical properties as the maximum load at failure for all 3-LP repair. Results The normal Achilles tendon—control group—failed at a mean load of 25.5 + 13.6; the experimental groups failed at a significantly lower load (p < 0.001), with the group of 3-LP suture with polypropylene mesh included in the suture being the more similar to controls, but all the groups exhibited statistically significant differences with regard to normal tendons (p < 0.001). The distance at which each group failed was also significant between control and experimental groups (p < 0.001) with the exception of the suture-only group and the group with the mesh over the suture (p = 0.15). Conclusion Results from this study suggest that incorporating the mesh within the suture provides benefit to the Achilles tendon repair by improving strength and resistance to pull through. However, further in vivo studies will be necessary to confirm these results and incorporate this technique to the routine human and veterinary surgery.

Abstract
BACKGROUND Electromyography signal amplitude is influenced by a variety of factors. Normalization strategies aimed at decreasing signal variability include using peak electromyography signal during a maximum voluntary contraction and peak-to-peak M-wave amplitude. However, whether these normalization methods are comparable has not been investigated in injured populations. This study investigated the relationship between peak signal during maximum voluntary contraction and M-wave amplitude in individuals with a unilateral Achilles tendon rupture. Secondarily, we observed whether the two normalizations strategies would yield similar results when evaluating between limb differences in muscle activity during a jump task. METHODS Eleven individuals 1-3 years after a unilateral Achilles tendon rupture were included in this study. Surface electromyography was used on the medial and lateral gastrocnemii bilaterally. Peak maximum voluntary contraction, M-wave amplitude, and electromyography during a jumping task were collected. FINDINGS A strong relationship was observed between peak maximum voluntary contraction and M-wave amplitude on the uninjured (r = 0.71-0.88, P < 0.05) but not on the ruptured side (r = 0.41-0.44, P > 0.05). The two normalization techniques did not produce different results when comparing the uninjured and ruptured sides. INTERPRETATION The findings of this study suggest that M-wave normalization yields similar results as peak maximum voluntary contraction-normalized electromyography in uninjured conditions. M-wave normalization may be a useful strategy in an injured population where a maximal muscle contraction is unsafe or impaired.

Abstract
PURPOSE Optimizing tendon structural recovery during the first 12 weeks after Achilles tendon rupture is a prime target to improve patient outcomes, but a comprehensive understanding of biomarkers is needed to track early healing. The purpose of this study was to observe healing of tendon structure over time using ultrasound-based, tendon-specific measures and to identify relationships between tendon structural characteristics and clinical measures of gait and strength. METHODS Twenty-seven participants (21 males, mean (SD) age 39 (11) years) were assessed at 4, 8, 12, and 24 weeks after injury or surgery using ultrasound imaging techniques. Gait analysis and strength testing were added at the later time points. RESULTS Ruptured tendons had significantly lower dynamic shear modulus (p < 0.001), greater tendon cross-sectional area (p < 0.001), and greater length (p < 0.001) than the uninjured side. Dynamic shear modulus, cross-sectional area, and length were found to increase over time (p < 0.01). Tendon structure at 4 weeks post-injury [cross-sectional area symmetry (r = 0.737, p = 0.002) and dynamic shear modulus (r = 0.518, p = 0.040)] related to stance phase walking symmetry at 24 weeks. CONCLUSIONS Tendon structure assessed by ultrasound imaging changes over the first 24 weeks of healing after Achilles tendon rupture, suggesting it could be used as a biomarker to track tendon healing early in recovery. Additionally, tendon structure within the first 12 weeks relates to later walking gait and heel-rise symmetry, which may indicate that tendon structure could have prognostic value in the care of these patients. This study's clinical relevance is in its support for using ultrasound imaging to assess early patient healing and prognosticate later patient outcomes after Achilles tendon rupture. LEVEL OF EVIDENCE Level 2, prospective cohort prognostic study.

Abstract
BACKGROUND Acute Achilles tendon rupture (ATR) has increased in the past decade, and many new treatments and rehabilitation regimens have been introduced. But major complications in ATR management remain an unsolved problem. PURPOSE To compare the risk of major complications of acute ATR after different combinations of treatments and rehabilitation regimens. STUDY DESIGN Systematic review and network meta-analysis. METHOD The authors searched 4 databases (PubMed, Medline, Embase, and the Cochrane Library) from the date of inception until February 2018 for articles in English. The authors considered randomized controlled trials comparing interventions and rehabilitation protocols for acute ATR and restricted (1) interventions to nonoperative treatment, minimally invasive surgery, and open surgery and (2) rehabilitation protocols to accelerated rehabilitation and early immobilization. Major complications were assessed-namely, rerupture, deep infection, and deep vein thrombosis (DVT). Only patients with primary acute ATR were considered. Quality assessment was performed with the Cochrane "risk of bias" tool. A series of additional tests were conducted to ensure the validity of the results. RESULTS Twenty-nine randomized controlled trials with 2060 patients were included in this Bayesian network meta-analysis. The mean incidence of overall major complications from all managements was 9.13% (median, 6.67%). The mean incidence rates of rerupture, deep infection, and DVT from all managements were 5%, 1.50%, and 2.67%, respectively. According to relative risk, nonoperative treatment combined with early immobilization was significantly associated with a higher risk of major complications. According to the surface under the cumulative ranking curve, minimally invasive surgery with accelerated rehabilitation had the highest possibility (79.7%) of being the best management with regard to minimizing major complications. CONCLUSION For treating acute ATR, management combining minimally invasive surgery with accelerated rehabilitation had the highest possibility of being superior in terms of major complication risks, according to the surface under the cumulative ranking curve. Management combining nonoperative treatment with early immobilization was statistically associated with a higher risk of complications as compared with the other methods of management.

Abstract
BACKGROUND Orthopaedic boots with wedging are commonly used in the treatment of individuals with Achilles tendon rupture to immobilize the foot in plantar flexion and approximate tendon ends. RESEARCH QUESTION To describe changes in muscle activity of the triceps surae and gait mechanics with the use of wedges in an orthopaedic boot immediately and after an accommodation period. METHODS Muscle activity of the triceps surae and gait parameters (vertical ground reaction force, knee extension power, gait speed) were collected using surface electromyography and motion capture in 12 healthy individuals. Participants walked in an instrumented orthopaedic boot with 0, 3, and 5 wedges tested in random order. Participants were provided a one hour accommodation period where time spent walking was collected. This was followed by a repeat assessment of triceps surae activity and gait. RESULTS Peak and integrated EMG in the medial gastrocnemius (p = 0.001, p < 0.001) and soleus (p = 0.010, p < 0.001) significantly decreased with increasing number of wedges. Peak and integrated EMG had a slight but non-significant decrease with increasing number of wedges in the lateral gastrocnemius (p = 0.151, p = 0.077). Vertical ground reaction force decreased (p = 0.019) and peak knee extension power increased (p = 0.003) with increasing number of wedges. There were no statistically significant differences in gait speed with wedges (p = 0.450). There were no significant changes in EMG or gait parameters from pre- to post-accommodation period. SIGNIFICANCE A combination of factors yield decreased triceps surae activity in individuals wearing an orthopaedic boot with wedges - decreasing loading on the immobilized limb and shifting power generation proximally.

Abstract
The purpose of this study was to characterize the short-term effects of Achilles tendon ruptures on medial gastrocnemius. We hypothesized that the fascicles of the medial gastrocnemius muscle of the injured Achilles tendon would be shorter and more pennate immediately following the injury and would persist throughout 4 weeks post-injury. B-mode longitudinal ultrasound images of the medial gastrocnemius were acquired in 10 adults who suffered acute Achilles tendon ruptures and were treated non-operatively. Ultrasound images were acquired during the initial clinical visit following injury as well as 2 and 4 weeks following this initial clinical visit. Resting muscle structure was characterized by measuring fascicle length, pennation angle, muscle thickness, and muscle echo intensity in both the injured and contralateral (control) limbs. Fascicle length was 15% shorter (P < 0.001) and pennation angle was 21% greater (P < 0.001) in the injured muscle compared to the uninjured (control) muscle at the presentation of injury (week 0). These differences in fascicle length persisted through 4 weeks after injury (P < 0.002) and pennation angle returned to pre-injury levels. Muscle thickness changes were not detected at any of the post-injury visits (difference < 4%, P > 0.026). Echo intensity of the injured limb was 8% lower at the presentation of the injury but was not different compared to the contralateral muscle at 2 and 4 weeks post-injury. Our results suggest that Achilles tendon ruptures elicit rapid changes in the configuration of the medial gastrocnemius, which may explain long-term functional deficits.

Abstract
Achilles tendon rupture leads to long term plantar flexor deficits. The purpose of this study was to describe changes in jumping biomechanics along with triceps surae structure and activation in individuals after Achilles repair. Eleven individuals 1-3 years following Achilles repair and 10 healthy controls were included. Kinetics and kinematics, analyzed using a constituent lower extremity work (CLEW) approach, and muscle activity using surface electromyography (EMG) were collected during a unilateral hopping task. Triceps surae myotendinous structure was assessed using ultrasound imaging. There were no differences in jump height, absolute limb work, or cost of transport between groups. During takeoff, the knee did more (p < 0.001) and ankle did less concentric work (p < 0.001), and lateral gastrocnemius rate of rise was higher (p = 0.02) on the ruptured side. During landing, the knee did more eccentric work (p = 0.033) and lateral gastrocnemius (p = 0.003) and soleus (p = 0.02) activation amplitude prior to landing was higher on the ruptured side. Individuals after Achilles tendon repair shift work toward the knee and alter muscle recruitment. Differences in lateral gastrocnemius activity may indicate that it is well-situated to generate power during takeoff and assist in landing with the soleus. The lack of change in muscle activity and decreased cross sectional area of the medial gastrocnemius may suggest that this muscle atrophies and does not accommodate to the hopping task. Clinical Significance: Proximal lower extremity strengthening along with emphasizing medial gastrocnemius and soleus activation during the recovery of patients with Achilles tendon repair may be rehabilitative targets for improved jumping performance. © 2019 Orthopaedic Research Society.

Abstract
Objectives The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits. Methods A PubMed search about the management of acute Achilles tendon rupture was performed. The search was open for original manuscripts and review papers limited to publication from January 2006 to July 2017. A total of 489 papers were identified initially and finally 323 articles were suitable for this review. Results The treatments of acute Achilles tendon rupture include operative and nonoperative treatments. Operative treatments mainly consist of open repair, percutaneous repair, mini-open repair, and augmentative repair. Traditional open repair has lower re-rupture rates with higher risks of complications. Percutaneous repair and mini-open repair show similar re-rupture rates but lower overall complication rates when compared with open repair. Percutaneous repair requires vigilance against nerve damage. Functional rehabilitation combining protected weight-bearing and early controlled motion can effectively reduce re-rupture rates with satisfactory outcomes. Biological adjuncts help accelerating tendon healing by adhering rupture ends or releasing highly complex pools of signalling factors. Conclusion The optimum treatment for complete rupture remains controversial. Both mini-open repair and functional protocols are attractive alternatives, while biotherapy is a potential future development. Cite this article: X. Yang, H. Meng, Q. Quan, J. Peng, S. Lu, A. Wang.

Abstract
Surgical repair of tendons of the foot and ankle is performed utilizing various methods, including autografts, allografts, and synthetic grafts. Artelon is a synthetic biomaterial that is fabricated from wet-spun fibers of PCL-based polyurethane urea, and has, optimal mechanical properties compared with other grafting options. Because of excellent results of Artelon in ACL reconstruction, its use was explored in 3 foot and ankle cases: repair of Achilles, posterior tibial, and peroneal tendons. Artelon has proven to be a successful alternative for tendon repairs, with all 3 cases returning to full function within 8 to 16 weeks and with no complications related to the graft.

Abstract
BACKGROUND Although simple end-to-end repair of the Achilles tendon is common, many augmented repair protocols have been implemented for acute Achilles tendon rupture. However, whether augmented repair is better than nonaugmented repair of an acute Achilles tendon rupture is still unknown. PURPOSE To conduct a meta-analysis to determine whether augmented surgical repair of an acute Achilles tendon rupture improved subjective patient satisfaction without an increase in rerupture rates. Secondary outcomes assessed included infections, ankle range of motion, calf muscle strength, and minor complications. STUDY DESIGN Meta-analysis. METHODS A systematic literature search of peer-reviewed articles was conducted to identify all randomized controlled trials (RCTs) comparing augmented repair and nonaugmented repair for acute Achilles tendon rupture from January 1980 to August 2016 in the electronic databases of PubMed, Web of Science (SCI-E/SSCI/A&HCI), and EMBASE. The keywords (Achilles tendon rupture) AND (surg* OR operat* OR repair* OR augment* OR non-augment* OR end-to-end OR sutur*) were combined, and results were limited to human RCTs and controlled clinical trials published in the English language. Four RCTs involving 169 participants were eligible for inclusion; 83 participants were treated with augmented repair and 86 were treated with nonaugmented repair. RESULTS Augmented repair led to similar responses when compared with nonaugmented repair for acute Achilles tendon rupture (93% vs 90%, respectively; P = .53). The rerupture rates showed no significant difference for augmented versus nonaugmented repair (7.2% vs 9.3%, respectively; P = .69). No differences in superficial and deep infections occurred in augmented (7 infections) and nonaugmented (8 infections) repair groups during postoperative follow-up ( P = .89). The average incisional infection rate was 8.4% with augmented repair and 9.3% with nonaugmented repair. No significant differences in other complications were found between augmented (7.2%) and nonaugmented (8.1%) repair ( P = .80). CONCLUSION Augmented repair, when compared with nonaugmented repair, was not found to improve patient satisfaction or reduce rerupture rate or infection rate. These conclusions are based on 4 trials with small sample sizes, and larger randomized trials are required to confirm these results.

Abstract
Background Disproportionate end-range plantar flexion weakness, decreased passive stiffness, and inability to perform a heel rise on a decline after Achilles tendon repair are thought to reflect increased tendon compliance or tendon lengthening. Since this was first noted, we have performed stronger repairs and avoided stretching into dorsiflexion for the first 12 weeks after surgery. Hypothesis Using stronger repairs and avoiding stretching into dorsiflexion would eliminate end-range plantar flexion weakness and normalize passive stiffness. Study Design Case series; Level of evidence, 4. Methods Achilles repairs with epitendinous augmentation were performed on 18 patients. Plantar flexion torque, dorsiflexion range of motion (ROM), passive joint stiffness, and standing single-legged heel rise on a decline were assessed at 43 ± 24 months after surgery (range, 9 months to 8 years). Maximum isometric plantar flexion torque was measured at 20° and 10° of dorsiflexion, neutral position, and 10° and 20° of plantar flexion. Passive dorsiflexion ROM was measured with a goniometer. Passive joint stiffness was computed from the increase in passive torque from 10° to 20° of dorsiflexion. Tendon thickness was measured by use of digital calipers. Plantar flexion electromyographic (EMG) data were recorded during strength and functional tests. Analysis of variance and chi-square tests were used to assess weakness and function. Results Marked weakness was evident on the involved side at 20° of plantar flexion (deficit, 26% ± 18%; P < .001), with no weakness at 20° of dorsiflexion (deficit, 6% ± 17%; P = .390). Dorsiflexion ROM was decreased 5.5° ± 8° (P = .015), and tendon width was 8 ± 3 mm greater on the involved side (P < .001). Passive joint stiffness was similar between the involved and noninvolved sides. Only 2 of 18 patients could perform a decline heel rise on the involved side compared with 18 of 18 on the noninvolved side (P = .01). No difference in EMG amplitude was found between the involved and noninvolved sides during the strength or heel rise tests. Conclusion The use of stronger repair techniques and attempts to limit tendon elongation by avoiding dorsiflexion stretching did not eliminate weakness in end-range plantar flexion. EMG data confirmed that end-range weakness was not due to neural inhibition. Physiological changes that alter the force transmission capability of the healing tendon may be responsible for this continued impairment. This weakness has implications for high-demand jumping and sprinting after Achilles tendon repair.

Abstract
BACKGROUND This study compared outcomes after treatment of acute Achilles tendon (AT) rupture via percutaneous suturing, with those after chronic AT rupture treated via open reconstruction. METHODS This retrospective study included 30 patients who underwent either percutaneous suturing for acute AT rupture (group AR, n=16) or open reconstruction for chronic AT rupture (group CR, n=14). Function was evaluated by calf muscle circumference, and endurance through isokinetic measurement and single-leg heel-rise test. Score evaluation included AT Total Rupture Score, Victorian Institute of Sports Assessment-Achilles questionnaire, and visual analogue scale pain score. Postoperative tendon thickness was measured using ultrasonography and MRI. RESULTS Follow-up was conducted 4.97±1.79 years postoperatively. The groups were similar in age and body mass index. There was no significant difference between groups in calf circumference, isokinetic measurement, heel-rise test, and score evaluation. There was significantly less mediolateral tendon thickening in group AR compared with group CR on ultrasonography (p=0.01) and MRI (p=0.001). CONCLUSIONS Open reconstruction for chronic AT rupture may result in comparable clinical and functional outcomes, but a thicker tendon compared with percutaneous suturing after acute AT rupture.

Abstract
Participation in sports activity has increased significantly during the last several decades. This phenomenon has exposed orthopedic sports medicine surgeons to new challenges regarding the diagnosis and management of common sport-related injuries. Arthroscopy is becoming more commonly used in many of the surgical procedures for these injuries and carries the risk of complications. Wound and nerve complications make up the bulk of complications in most procedures. This article describes these complications associated with the common surgical procedures related to foot and ankle sport-related injuries and how to address and prevent them.

Abstract
BACKGROUND Following Achilles tendon rupture, tendon elongation leads to long term deficits in calf function. A surrogate measure of Achilles tendon length, Achilles tendon resting angle (ATRA), has been described but has not been validated against length measured using ultrasound. Therefore, the purpose of this study was to validate the ATRA against ultrasound. Secondarily, this study aimed to identify the relationship of other factors (tendon mechanical properties, heel-rise test performance) to the ATRA. METHODS Individuals following unilateral Achilles tendon rupture were included. ATRA was measured in knee flexed and extended positions. Tendon elongation was measured using extended field of view ultrasound imaging. Continuous shear wave elastography quantified tendon mechanical properties. The relationship between variables was tested using Spearman's ρ. Subgroup analysis was used to compare subjects with less then or greater than 1 year following rupture. A total of 42 participants (with a mean of 18.2 months following rupture [SD = 35.9]) were included. RESULTS Tendon elongation related with relative ATRA with knee flexed (ρ = .491, P = .001) and knee extended (ρ = 0.501, P = .001) positions. In individuals greater than 1 year following rupture, relative ATRA with the knee flexed related to shear modulus (ρ = .800, P = .01) and total work on the heel-rise test (ρ = -.782, P = .008) relative to the uninjured side. CONCLUSION Relative ATRA in both knee flexed and knee extended positions has a moderate relationship to tendon elongation within the first year following rupture. After 1 year, the relative ATRA with knee flexed may be a better indicator of tendon elongation and also related to tendon mechanical properties and heel-rise test performance.

Abstract
Chronic Achilles tendon ruptures are debilitating injuries and are often associated with large tendon gaps that can be challenging for the foot and ankle surgeon to treat. Preoperative evaluation should include the patient's functional goals, medical comorbidities, MRI assessment of gastrocsoleus muscle viability, condition of adjacent flexor tendons, and size of the tendon defect. Although several surgical techniques have been described, the surgeon must formulate an individualized treatment plan for the patient. This article reviews the principles of diagnosis, treatment options, and clinical outcomes, and outlines the authors' preferred techniques.

Abstract
BACKGROUND AND AIM OF THE WORK Achilles tendon rupture is frequent and can result in a disabling condition. The ideal method of management remains a matter of debate. We aimed to compare the clinical outcome of patients who underwent surgical repair of Achilles tendon rupture with Silfverskiöld augmentation technique with gastrocnemius fascia flap versus Krackow end-to-end stitching technique. METHODS We retrospectively studied all patients that were surgically treated for Achilles tendon rupture at our institution, between January 2000 and December 2015, using either Silfverskiöld or Krackow technique. We excluded all patients deceased or untreaceble, and those refusing the follow up interview. Disability, Quality-of-Life and functional restriction were evaluated using the Achilles-Tendon-total-Rupture-Score (ATRS) and Foot-and-Ankle-Disability-Index (FADI); means were compared by the Mann-Whitney test and correlations by the Spearman coefficient. RESULTS A total of 90 patients were included, with a mean age of 45.3±12.6 years. The augmented repair group-A included 33 patients and the simple repair group-B 57 patients. Follow-up averaged 8 years (1 to 16). FADI was 103.7±1.6 for group-A versus 100.3±15.6 for group-B. ATRS was 2.0±7.1 and 5.7±18.8, respecitvely. Differences were not significant. Age showed a low linear correlation with ATRS (R=0.41) and FADI (R=-0.40), indicating that clinical outcomes minimally tend to worsen in older patients. CONCLUSIONS We didn't find significative differences in the clinical outcomes between the two groups of patients. Acute uncomplicated Achilles tendon ruptures can be successfully treated with a direct suture technique. Augmentation with a fascial flap should be reserved to chronic or neglected cases with severe tendinosis or tissue defect.

Abstract
BACKGROUND In this prospective study, we used magnetic resonance imaging (MRI) to assess long-term Achilles tendon length, calf muscle volume, and muscle fatty degeneration after surgery for acute Achilles tendon rupture. METHODS From 1998 to 2001, 60 patients at our center underwent surgery for acute Achilles tendon rupture followed by early functional postoperative rehabilitation. Fifty-five patients were reexamined after a minimum duration of follow-up of 13 years (mean, 14 years), and 52 of them were included in the present study. Outcome measures included Achilles tendon length, calf muscle volume, and fatty degeneration measured with MRI of both the affected and the uninjured leg. The isokinetic plantar flexion strength of both calves was measured and was correlated with the structural findings. RESULTS The Achilles tendon was, on average, 12 mm (95% confidence interval [CI] = 8.6 to 15.6 mm; p < 0.001) longer (6% longer) in the affected leg than in the uninjured leg. The mean volumes of the soleus and medial and lateral gastrocnemius muscles were 63 cm (13%; p < 0.001), 30 cm (13%; p < 0.001), and 16 cm (11%; p < 0.001) lower in the affected leg than in the uninjured leg, whereas the mean volume of the flexor hallucis longus (FHL) was 5 cm (5%; p = 0.002) greater in the affected leg, indicating FHL compensatory hypertrophy. The median plantar flexion strength for the whole range of motion ranged from 12% to 18% less than that on the uninjured side. Finally, the side-to-side difference in Achilles tendon length correlated substantially with the strength deficit (ρ = 0.51, p < 0.001) and with medial gastrocnemius (ρ = 0.46, p = 0.001) and soleus (ρ = 0.42, p = 0.002) muscle atrophy. CONCLUSIONS Increased Achilles tendon length is associated with smaller calf muscle volumes and persistent plantar flexion strength deficits after surgical repair of Achilles tendon rupture. Strength deficits and muscle volume deficits are partly compensated for by FHL hypertrophy, but 11% to 13% deficits in soleus and gastrocnemius muscle volumes and 12% to 18% deficits in plantar flexion strength persist even after long-term follow-up.

Abstract
Background: The aim of management of Achilles tendon rupture is to reduce tendon lengthening and maximize function while reducing the rerupture rate and minimizing other complications. Purpose: To determine changes in Achilles tendon resting angle (ATRA), heel-rise height, patient-reported outcomes, return to play, and occurrence of complications after minimally invasive repair of Achilles tendon ruptures using nonabsorbable sutures. Study Design: Cohort study; Level of evidence, 3. Methods: Between March 2013 and August 2015, a total of 70 patients (58 males, 12 females) with a mean age of 42 ± 8 years were included and evaluated at 6 weeks and 3, 6, 9, and 12 months after repair of an Achilles tendon rupture. Surgical repair was performed using either 4-strand or 6-strand nonabsorbable sutures. After surgery, patients were mobilized, fully weightbearing using a functional brace. Early active movement was permitted starting at 2 weeks. Results: There were no significant differences in the ATRA, Achilles Tendon Total Rupture Score (ATRS), and Heel-Rise Height Index (HRHI) between the 4- and 6-strand repairs. The mean (SD) relative ATRA was –13.1° (6.6°) (dorsiflexion) following injury; this was reduced to 7.6° (4.8°) (plantar flexion) directly after surgery. During initial rehabilitation at 6 weeks, the relative ATRA was 0.6° (7.4°) (neutral) and –7.0° (5.3°) (dorsiflexion) at 3 months, after which ATRA improved significantly with time to 12 months (P = .005). At 12 months, the median ATRS was 93 (range, 35-100), and the mean (SD) HRHI and Heel-Rise Repetition Index were 81% (0.22%) and 82.9% (0.17%), respectively. The relative ATRA at 3 and 12 months correlated with HRHI (r = 0.617, P < .001 and r = 0.535, P < .001, respectively). Conclusion: Increasing the number of suture strands from 4 to 6 does not alter the ATRA or HRHI after minimally invasive Achilles tendon repair. The use of a nonabsorbable suture during minimally invasive repair when used together with accelerated rehabilitation did not prevent the development of an increased relative ATRA. The ATRA at 3 months after surgery correlated with heel-rise height at 12 months.

Abstract
Background Rupture of the Achilles tendon often leads to long-term morbidity, particularly calf weakness associated with tendon elongation. Operative repair of Achilles tendon ruptures leads to reduced tendon elongation. Tendon lengthening is a key problem in the restoration of function following Achilles tendon rupture. A study was performed to determine differences in initial separation, strength and failure characteristics of differing sutures and numbers of core strands in a percutaneous Achilles tendon repair model in response to initial loading. Methods Nineteen bovine Achilles tendons were repaired using a percutaneous/minimally invasive technique with a combination of a modified Bunnell suture proximally and a Kessler suture distally, using non-absorbable 4-strand 6-strand repairs and absorbable 8-strand sutures. Specimens were then cyclically loaded using phases of 10 cycles of 100 N, 100 cycles of 100 N, 100 cycles of 190 N consistent with early range of motion training and weight-bearing, before being loaded to failure. Results Pre-conditioning of 10 cycles of 100 N resulted in separations of 4 mm for 6-strand, 5.9 mm for 4-strand, but 11.5 mm in 8-strand repairs, this comprised 48.5, 68.6 and 72.7% of the separation that occurred after 100 cycles of 100 N. The tendon separation after the third phase of 100 cycles of 190 N was 17.4 mm for 4-strand repairs, 16.6 mm for 6-strand repairs and 26.6 mm for 8-strand repairs. There were significant differences between the groups (p < 0.0001). Four and six strand non-absorbable repairs had significantly less separation than 8-strand absorbable repairs (p = 0.017 and p = 0.04 respectively). The mean (SEM) ultimate tensile strengths were 4-strand 464.8 N (27.4), 6-strand 543.5 N (49.6) and 8-strand 422.1 N (80.5). Regression analysis reveals no significant difference between the overall strength of the 3 repair models (p = 0.32) (4 vs. 6: p = 0.30, 4 vs. 8: p = 0.87; 6 vs. 8: p = 0.39). The most common mode of failure was pull out of the Kessler suture from the distal stump in 41.7% of specimens. Conclusion The use of a non-absorbable suture resulted in less end-to-end separation when compared to absorbable sutures when an Achilles tendon repair model was subject to cyclical loading. Ultimate failure occurred more commonly at the distal Kessler suture end although this occurred with separations in excess of clinical failure. The effect of early movement and loading on the Achilles tendon is not fully understood and requires more research.

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
BACKGROUND It remains controversial whether nonsurgical or surgical treatment provides better calf muscle strength recovery after an acute Achilles tendon rupture (ATR). Recent evidence has suggested that surgery might surpass nonsurgical treatment in restoring strength after an ATR. PURPOSE To assess whether magnetic resonance imaging (MRI) findings could explain calf muscle strength deficits and the difference between nonsurgical and surgical treatments in restoring calf muscle strength. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS From 2009 to 2013, 60 patients with acute ATRs were randomized to surgery or nonsurgical treatment with an identical rehabilitation protocol. The primary outcome measure was the volume of calf muscles assessed using MRI at 3 and 18 months. The secondary outcome measures included fatty degeneration of the calf muscles and length of the affected Achilles tendon. Additionally, isokinetic plantarflexion strength was measured in both legs. RESULTS At 3 months, the study groups showed no differences in muscle volumes or fatty degeneration. However, at 18 months, the mean differences between affected and healthy soleus muscle volumes were 83.2 cm3 (17.7%) after surgery and 115.5 cm3 (24.8%) after nonsurgical treatment (difference between means, 33.1 cm3; 95% CI, 1.3-65.0; P = .042). The study groups were not substantially different in the volumes or fatty degeneration of other muscles. From 3 to 18 months, compensatory hypertrophy was detected in the flexor hallucis longus (FHL) and deep flexors in both groups. In the nonsurgical treatment group, the mean difference between affected and healthy FHL muscle volumes was -9.3 cm3 (12%) and in the surgical treatment group was -8.4 cm3 (10%) ( P ≤ .001). At 18 months, Achilles tendons were, on average, 19 mm longer in patients treated nonsurgically compared with patients treated surgically ( P < .001). At 18 months, surgically treated patients demonstrated 10% to 18% greater strength results ( P = .037). Calf muscle isokinetic strength deficits for the entire range of ankle motion correlated with soleus atrophy (ρ = 0.449-0.611; P < .001). CONCLUSION Treating ATRs nonsurgically with a functional rehabilitation protocol resulted in greater soleus muscle atrophy compared with surgical treatment. The mean Achilles tendon length was 19 mm longer after nonsurgical treatment than after the surgical treatment of ATRs. These structural changes partly explained the 10% to 18% greater calf muscle strength observed in patients treated with surgery compared with those treated nonsurgically.

Abstract
BACKGROUND The optimal treatment of acute Achilles tendon ruptures for active patients is under debate. PURPOSE To compare clinical outcomes and calf muscle strength recovery after the nonsurgical treatment and open surgical repair of acute Achilles tendon ruptures with identical accelerated rehabilitation programs. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS From 2009 to 2013, a total of 60 patients with an acute Achilles tendon rupture were randomized to surgery or nonsurgical treatment. Nonsurgical treatment included first a week of cast immobilization, followed by a functional orthosis for 6 weeks, allowing full weightbearing after week 1 and active plantar flexion after week 5. Surgery was simple end-to-end open repair, and postoperative treatment was identical to nonsurgical treatment. Outcome measures included the Leppilahti Achilles tendon performance score, isokinetic calf muscle strength, and RAND 36-Item Health Survey at 18-month follow-up. RESULTS At 18-month follow-up, the mean Leppilahti score was 79.5 and 75.7 for the surgically and nonsurgically treated groups, respectively (mean difference, 3.8; 95% CI, -1.9 to 9.5; P = .19). Angle-specific peak torque results of affected legs showed that surgery resulted in faster and better recovery of calf muscle strength over the entire range of motion of the ankle joint: at 6 months, the difference varied from 16% to 24% (P = .016), favoring the surgically treated group, whereas at 18 months, surgically treated patients had 10% to 18% greater strength results (P = .037). At 18 months, a 14% difference in the peak torque of the affected leg favored the surgical group versus the nonsurgical group (mean peak torque, 110.3 vs 96.5 N·m, respectively; mean difference, 13.6 N·m; 95% CI, 2.0-25.1 N·m; P = .022). The RAND 36-Item Health Survey indicated better results in the domains of physical functioning (P = .006) and bodily pain (P = .037) for surgically treated patients. CONCLUSION Surgical and nonsurgical treatments of acute Achilles tendon ruptures have similar results in terms of the Achilles tendon performance score, but surgery restores calf muscle strength earlier over the entire range of motion of the ankle joint, with a 10% to 18% strength difference favoring surgery at 18 months. Surgery may also result in better health-related quality of life in the domains of physical functioning and bodily pain compared with nonsurgical treatment.
