Abstract
BACKGROUND Achilles tendon rupture (ATR) is a significant injury that can require surgery and can have the risk of re-rupture even after successful treatment. Consequently, to minimize this risk, it is important to have a thorough understanding of the rehabilitation protocol and the impact of different rehabilitation approaches on preventing re-rupture. MATERIALS AND METHODS Two independent team members searched several databases (PubMed, EMBASE, Web of Science, Cochrane Library, and CINAHL) to identify randomized controlled trials (RCTs) on operative treatment of ATR. We included articles that covered open or minimally invasive surgery for ATR, with a detailed rehabilitation protocol and reports of re-rupture. The study protocol has been registered at PROSPERO and has been reported in the line with PRISMA Guidelines, Supplemental Digital Content 1, http://links.lww.com/JS9/C85 , Supplemental Digital Content 2, http://links.lww.com/JS9/C86 and assessed using AMSTAR Tool, Supplemental Digital Content 3, http://links.lww.com/JS9/C87 . RESULTS A total of 43 RCTs were eligible for the meta-analysis, encompassing a combined cohort of 2553 patients. Overall, the postoperative incidence of ATR patients developing re-rupture was 3.15% (95% CI: 2.26-4.17; I2 =44.48%). Early immobilization group patients who had ATR had a 4.07% (95% CI: 1.76-7.27; I2 =51.20%) postoperative incidence of re-rupture; Early immobilization + active range of motion (AROM) group had an incidence of 5.95% (95% CI: 2.91-9.99; I2 =0.00%); Early immobilization + weight-bearing group had an incidence of 3.49% (95% CI: 1.96-5.43; I2 =20.06%); Early weight-bearing + AROM group had an incidence of 3.61% (95% CI: 1.00-7.73; I2 =64.60%); Accelerated rehabilitation (immobilization) group had an incidence of 2.18% (95% CI: 1.11-3.59; I2 =21.56%); Accelerated rehabilitation (non-immobilization) group had a rate of 1.36% (95% CI: 0.12-3.90; I2 =0.00%). Additionally, patients in the immediate AROM group had a postoperative re-rupture incidence of 3.92% (95% CI: 1.76-6.89; I2 =33.24%); Non-immediate AROM group had an incidence of 2.45% (95% CI: 1.25-4.03; I2 =22.09%). CONCLUSIONS This meta-analysis suggests the use of accelerated rehabilitation intervention in early postoperative rehabilitation of the Achilles tendon. However, for early ankle joint mobilization, it is recommended to apply after one to two weeks of immobilization.

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
INTRODUCTION An acute Achilles tendon rupture represents a common tendon injury, and its operative methods have been developed over the years. This study aimed to quantify the learning curve for the minimally invasive acute Achilles tendon rupture repair. METHODS From May 2020 to June 2022, sixty-seven patient cases who received minimally invasive tendon repair were reviewed. Baseline data and operative details were collected. The cumulative summation (CUSUM) control chart was used for the learning curve analyses. Achilles tendon rupture score (ATRS), American Orthopedic Foot and Ankle Society (AOFAS) ankle/hindfoot score, and visual analog scale (VAS) at 3/6/9/12 months were calculated to assess the clinical outcomes. RESULTS Thirty-six cases underwent at least a year of follow up and were enrolled in this study. The gender ratio and average age were 80.5% and 32.5 years. The linear equation fitted well (R2 = 0.95), and CUSUM for operative time peaked in the 12th case, which was divided into the learning phase (n = 12) and master phase (n = 24). No significant difference was detected between the two groups in clinical variables, except for the operative time (71.1 ± 13.2 min vs 45.8 ± 7.2 min, p = 0.004). Moreover, we detected one case with a suture reaction and treated it properly. CONCLUSION Minimally invasive Achilles repair provides an opportunity for early rehabilitation. Notably, the learning curve showed that the "lumbar puncture needle and oval forceps" technique was accessible to surgeons.

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 Long-term strength deficits are common after Achilles tendon ruptures. Early use of progressive resistance exercises may help reduce strength deficits, but the feasibility of this approach is unknown. The aim was to investigate the feasibility of early progressive resistance exercises regarding patient acceptability and compliance with the intervention. METHODS We recruited patients with an acute Achilles tendon rupture treated non-surgically. During 9 weeks of immobilisation with a walking boot, participants attended weekly supervised physiotherapy sessions of progressive resistance exercises and performed home exercises, consisting of isometric ankle plantarflexion, seated heel-rise, and elastic band exercises. Acceptability was evaluated using a 7-point Likert scale (1 = very unacceptable and 7 = very acceptable) with feasibility threshold at 80% of the participants rating ≥ 4. Adherence to the exercises was defined as 80% of the participants performing at least 50% of the home exercises. During the intervention, tendon healing and adverse events were monitored. RESULTS Sixteen participants (mean age 46 (range 28-61), male/female = 13/3) completed the intervention. Pre-injury Achilles tendon total rupture score was 98 (SD 8). All participants rated the acceptability of the exercises ≥ 5 (moderate acceptable to very acceptable) at 9- and 13-week follow-up and 9/16 rated 7 points (very acceptable). Participants performed 74% (range 4-117) of the total prescribed home exercises and 15/16 performed > 50%. One participant was not compliant with the home exercises due to feeling uncomfortable performing these independently. There were no re-ruptures, but one case of deep venous thrombosis. CONCLUSIONS The early progressive resistance exercise program for treatment of non-surgically treated Achilles tendon rupture was feasible. Future studies should investigate the efficacy of the progressive intervention. TRIAL REGISTRATION The study was registered at Clinical Trials (NCT04121377) on 29 September 2019.

Abstract
BACKGROUND Achilles tendon ruptures often result in long-term functional deficits despite accelerated (standard) rehabilitation. PURPOSE/HYPOTHESIS The purpose of this study was to investigate if delayed loading would influence functional, clinical, and structural outcomes of the muscles and tendon 1 year after a surgical repair. It was hypothesized that delaying the loading would reduce the heel-rise height deficit 1 year after Achilles tendon rupture. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS In total, 48 patients with a surgically repaired Achilles tendon rupture were randomized to 2 groups: the standard group received the currently accepted rehabilitation, and the delayed group received the same rehabilitation except that initial loading was delayed by 6 weeks. The primary outcome was the heel-rise height difference between the injured and uninjured sides at 1 year. The secondary outcomes were (1) tendon length measured with magnetic resonance imaging, (2) muscle fascicle length and pennation angle of the gastrocnemius medialis muscle, (3) Doppler activity measured with ultrasonography, (4) Achilles tendon Total Rupture Score (ATRS), and (5) isometric muscle strength. RESULTS The mean heel-rise height deficits for the standard and delayed groups were -2.2 cm and -2.1 cm, respectively (P = .719). The soleus part of the tendon was already elongated 1 week after surgery in both groups without a between-group difference (side-to-side difference: standard, 16.3 mm; delayed, 17.5 mm; P = .997) and did not change over 52 weeks. The gastrocnemius tendon length was unchanged at 1 week but elongated over time without a between-group difference (side-to-side difference at 52 weeks: standard, 10.5 mm; delayed, 13.0 mm; P = .899). The delayed group had less Doppler activity at 12 weeks (P = .006) and a better ATRS (standard, 60 points; delayed, 72 points; P = .032) at 52 weeks. CONCLUSION Delayed loading was not superior to standard loading in reducing the heel-rise height difference at 1 year. The data indirectly suggested reduced inflammation in the initial months and a better patient-reported outcome at 1 year in the delayed group. The soleus part of the tendon was already markedly elongated (35%) 1 week after surgery, while the length of the gastrocnemius tendon was unchanged at 1 week but was 6% elongated at 1 year. Together, these data indirectly suggest that the delayed group fared better, although this finding needs to be confirmed in future investigations.

Abstract
BACKGROUND Rotator cuff (RC) tendinopathy is the most reported shoulder disorder in the general population with highest prevalence in overhead athletes and adult working-age population. A growing body of evidence support exercise therapy as an effective intervention, but to date there are no prospective randomized controlled trials addressing pain as an intervention variable. METHODS A single-site, prospective, pragmatic, assessor-blinded randomized controlled superiority trial. Eighty-four patients aged 18-55 years with chronic (symptom duration over 3 months) RC tendinopathy are randomized 1:1 to receive shoulder exercise during which pain is either allowed or avoided. The intervention period lasts 26 weeks. During that period, participants in both groups are offered 8 individual on-site sessions with an assigned sports physiotherapist. Participants perform home exercises and are provided with a pain and exercise logbook and asked to report completed home-based exercise sessions and reasons for not completing sessions (pain or other reasons). Patients are also asked to report load and the number of sets and repetitions per sets for each exercise session. The logbooks are collected continuously throughout the intervention period. The primary and secondary outcomes are obtained at baseline, 6 weeks, 26 weeks, and 1 year after baseline. The primary outcome is patient-reported pain and disability using the Shoulder PAin and Disability Index (SPADI). Secondary outcomes are patient-reported pain and disability using Disability Arm Shoulder and Hand short-form (Quick DASH), and shoulder pain using Numeric Pain Rating Scale. Objective outcomes are shoulder range of motion, isometric shoulder muscle strength, pain sensitivity, working ability, and structural changes in the supraspinatus tendon and muscle using ultrasound. DISCUSSION The results of this study will contribute knowledge about the treatment strategies for patients with RC tendinopathy and help physiotherapists in clinical decision-making. This is the first randomized controlled trial comparing the effects of allowing pain versus avoiding pain during shoulder exercises in patients with chronic RC tendinopathy. If tolerating pain during and after exercise proves to be effective, it will potentially expand our understanding of "exercising into pain" for this patient group, as there is currently no consensus.

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
BACKGROUND A number of studies have reported that calf muscle atrophy is a common long-term problem after Achilles tendon repair; however, there is still a lack of data concerning early postoperative morphological changes in the calf muscle after surgery. PURPOSE To investigate changes over time in calf muscle volume and fatty degeneration during 1 year after Achilles tendon repair. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS A prospective 1-year serial magnetic resonance imaging study was carried out with 20 patients who underwent tendon repair for unilateral acute Achilles tendon rupture. The magnetic resonance imaging assessment in addition to clinical and functional evaluations was performed at 1, 3, 6, and 12 months after surgery. The muscle volume of the medial and lateral gastrocnemius, soleus, and flexor hallucis longus (FHL) and fatty degeneration of the medial and lateral gastrocnemius and soleus were measured for the calf muscles, and the relative volume and fatty degeneration changes in the affected leg compared with the healthy contralateral leg were calculated as a percentage ([injured/healthy control] × 100) to assess structural changes over time. RESULTS Muscle volumes of the medial gastrocnemius, lateral gastrocnemius, soleus, and FHL were 92.3%, 92.8%, 84.6%, and 95.9% at 12 months after surgery, respectively. Medial and lateral gastrocnemius and FHL muscle volumes improved over time and recovered to almost equal to that of the healthy side at 12 months after surgery. The soleus muscle volume did not recover significantly over time and was statistically significantly smaller than that of the healthy side at 12 months (P = .029). Fatty degeneration rates of the medial gastrocnemius, lateral gastrocnemius, and soleus were 118.2%, 113.9% and 121.1% at 12 months after surgery, respectively. Fatty degeneration of the medial and lateral gastrocnemius did not change significantly, but there was a statistically significant increase in fatty degeneration of the soleus over time (P < .001). CONCLUSION Within the triceps surae muscle, the soleus was the most negatively affected by injury and repair for both muscle volume and fatty degeneration. Postoperative management to recover the soleus muscle function before a return to sporting activities should be considered in the future.

Abstract
PURPOSE Differential elongation of the gastrocnemius after Achilles tendon rupture (ATR) may compromise the ability of athletes to return to competition. Recognition of this differential elongation of the gastrocnemius relative to the soleus is vital to treat patients with weakness in push-off. This paper describes a novel technique performed for selective shortening of the gastrocnemius to treat push-off weakness. METHODS Three patients with differential proximal retraction of the gastrocnemius greater than 20 mm after treatment for ATR with inability to run and jump underwent surgical correction with this novel technique and were followed-up for 2 years. A novel selective shortening of the gastrocnemius with autologous hamstring graft was performed in these patients. The Achilles Tendon Total Rupture Score (ATRS) and American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score were recorded preoperatively and at the final follow-up. RESULTS All three patients were able to return to running and jumping at final follow-up. The ATRS improved significantly in the strength, fatigue, running and jumping domains but there appeared to be a less notable improvement in activities of daily living domain. The AOFAS score showed improvement with the greatest margin in the domain of activity limitation. CONCLUSION This procedure is the first described selective shortening method of the gastrocnemius tendons after differential elongation following ATR. It is a safe and reliable technique providing improved ATRS and AOFAS scores in three patients who were all able to return to running and jumping sports at 2-year follow-up. LEVEL OF EVIDENCE IV.

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).

Abstract
OBJECTIVE When the endoscopic Achilles tendon repair technique is utilized, direct stitching of the ruptured site is challenging due to the frayed tendon stumps. To explore whether undesirable coaptation of the tendon stumps influences the generation of the tendons. METHODS This study is a retrospective analysis of 46 patients who underwent a modified endoscopic Achilles tendon rupture repair from October 2018 to June 2020. Patients were divided into two groups according to the coaptation of tendon stumps on postoperative ultrasonography. Group 1 included 17 cases with undesirable coaptation (<50%), and Group 2 included 29 cases with appropriate coaptation (≥50%). Magnetic resonance imaging (MRI) was obtained postoperatively at 3, 6, and 12 months to evaluate the tendon morphological construction. Clinical evaluations were performed using the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hind foot score, the Achilles Tendon Total Rupture Score (ATRS), muscle power, and the Achilles tendon resting angle at the final follow-up. Complications were also encountered. The Student's t-test and the Mann-Whitney U-test were used to assess differences among both groups. RESULTS The mean follow-up time was 37.5 ± 10.6 months in Group 1 and 39.0 ± 11.6 months in Group 2, respectively. The average age in Group 1 is slightly older than in Group 2 (37.3 ± 6.1 vs. 32.7 ± 6.3, p = 0.021). The tendon cross-section areas and thickness increased initially and decreased later on postoperative MRI evaluation. It also showed a significantly higher signal/noise quotient (SNQ) in Group 1 at postoperative 3 months. At postoperative 6 and 12 months, the SNQ between both groups was similar. The AOFAS score (95.9 ± 5.1 vs. 96.2 ± 4.9, p = 0.832), ATRS score (97.0 ± 3.6 vs. 97.7 ± 3.3, p = 0.527), and muscle power (21.38 vs. 24.74, p = 0.287) were not significantly different between both groups. However, the resting angle of Group 1 was significantly larger than that of Group 2 (4.6 ± 2.4 vs. 2.4 ± 2.3, p = 0.004). There was no difference in the complications (p = 0.628). CONCLUSION Although complete regeneration can be finally achieved, the early stage of tendon stump regeneration can be prolonged due to undesirable coaptation when endoscopic Achilles tendon repair technique is applied. The prolonged high signal duration on MRI indicates the less-than-ideal regeneration of the tendon, which might lead to elongation of the tendon.

J Appl Physiol (1985) 2023; 135:326-333.

Abstract
Permanent loss of muscle function seen after an Achilles tendon rupture may partly be explained by tendon elongation and accompanying shortening of the muscle. Muscle fascicle length shortens, serial sarcomere number is reduced, and the sarcomere length is unchanged after Achilles tendon transection (ATT), and these changes are mitigated with suturing. The method involved in this study was a controlled laboratory study. Two groups of rats underwent ATT on one side with a contralateral control (CTRL): A) ATT with 3 mm removal of the Achilles tendon and no suturing (substantial tendon elongation), and B) ATT with suture repair (minimal tendon elongation). The operated limb was immobilized for 2 wk to reduce load. Four weeks after surgery the rats were euthanized, and hindlimbs were analyzed for tendon length, gastrocnemius medialis (GM) muscle mass, length, fascicle length, sarcomere number and length. No differences were observed between the groups, and in both groups the Achilles tendon length was longer (15.2%, P < 0.001), GM muscle mass was smaller (17.5%, P < 0.001), and muscle length was shorter (8.2%, P < 0.001) on the ATT compared with CTRL side. GM fascicle length was shorter (11.2%, P < 0.001), and sarcomere number was lower (13.8%, P < 0.001) on the ATT side in all regions. Sarcomere length was greater in the proximal (5.8%, P < 0.001) and mid (4.2%, P = 0.003), but not distal region on the ATT side. In this animal model, regardless of suturing, ATT resulted in tendon elongation, loss of muscle mass and length, and reduced serial sarcomere number, which resulted in an "overshoot" lengthening of the sarcomeres.NEW & NOTEWORTHY Following acute Achilles tendon rupture, patients are often left with functional deficits. The specific reason remains largely unknown. The shortened muscle leads to reduced fascicle length, in turn leading to adaptation by reduced serial sarcomere numbers. Surprisingly, this adaptation appears to "overshoot" and lead to increased sarcomere length. The present animal model advances understanding of how muscle sarcomeres, which are difficult to measure in humans, are affected when undue elongation takes place after tendon rupture.

Abstract
BACKGROUND Optimum treatment for acute Achilles tendon rupture results in high mechanical strength, low risk of complications, and return to preinjury activity level. Percutaneous knotless repair is a minimally invasive technique with promising results in biomechanical studies, but few comparison clinical studies exist. Our study purpose was to compare functional outcomes and revision rates following acute Achilles tendon rupture treated between percutaneous knotless repair and open repair techniques. METHODS Patients 18 years or older with an acute Achilles tendon rupture, treated by a single surgeon with either open repair or percutaneous knotless repair, and more than 2 years after surgery were assessed for eligibility. Prospective clinical data were obtained from the data registry and standard electronic medical record. Additionally, the patients were contacted to obtain current follow-up questionnaires. Primary outcome measure was Foot and Ankle Ability Measure (FAAM) activities of daily living (ADL). Secondary outcome measures were FAAM sports, 12-Item Short Form Health Survey (SF-12), Tegner activity scale, patient satisfaction with outcome, complications, and revisions. Postoperative follow-up closest to 5 years was used in this study. RESULTS In total, 61 patients were included in the study. Twenty-four of 29 patients (83%) in the open repair group and 28 of 32 patients (88%) in the percutaneous knotless repair group completed the questionnaires with average follow-up of 5.8 years and 4.2 years, respectively. We found no significant differences in patient-reported outcomes or patient satisfaction between groups (FAAM ADL: 99 vs 99 points, P = .99). Operative time was slightly longer in the percutaneous knotless repair group (46 vs 52 minutes, P = .02). Two patients in the open group required revision surgery compared to no patients in the percutaneous group. CONCLUSION In our study, we did not find significant differences in patient-reported outcomes or patient satisfaction by treating Achilles tendon midsubstance ruptures with percutaneous knotless vs open repair.

Abstract
The Achilles tendon (AT) is the strongest tendon in humans, yet it often suffers from injury. The mechanical properties of the AT afford efficient movement, power amplification and power attenuation during locomotor tasks. The properties and the unique structure of the AT as a common tendon for three muscles have been studied frequently in humans using in vivo methods since 1990's. As a part of the celebration of 50 years history of the International Society of Biomechanics, this paper reviews the history of the AT research focusing on its mechanical properties in humans. The questions addressed are: What are the most important mechanical properties of the Achilles tendon, how are they studied, what is their significance to human movement, and how do they adapt? We foresee that the ongoing developments in experimental methods and modeling can provide ways to advance knowledge of the complex three-dimensional structure and properties of the Achilles tendon in vivo, and to enable monitoring of the loading and recovery for optimizing individual adaptations.

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
Effective countermeasures for tendon injury remains unsatisfactory. Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs)-based therapy via regulation of Mφ-mediated angiogenesis has emerged as a promising strategy for tissue regeneration. Still, approaches to tailor the functions of EVs to treat tendon injuries have been limited. We reported a novel strategy by applying MSC-EVs boosted with bioactive glasses (BG). BG-elicited EVs (EVB) showed up-regulation of medicinal miRNAs, including miR-199b-3p and miR-125a-5p, which play a pivotal role in M2 Mφ-mediated angiogenesis. EVB accelerated angiogenesis via the reprogrammed anti-inflammatory M2 Mφs compared with naïve MSC-EVs (EVN). In rodent Achilles tendon rupture model, EVB local administration activated anti-inflammatory responses via M2 polarization and led to a spatial correlation between M2 Mφs and newly formed blood vessels. Our results showed that EVB outperformed EVN in promoting tenogenesis and in reducing detrimental morphological changes without causing heterotopic ossification. Biomechanical test revealed that EVB significantly improved ultimate load, stiffness, and tensile modulus of the repaired tendon, along with a positive correlation between M2/M1 ratio and biomechanical properties. On the basis of the boosted nature to reprogram regenerative microenvironment, EVB holds considerable potential to be developed as a next-generation therapeutic modality for enhancing functional regeneration to achieve satisfying tendon regeneration.

Achilles tendon gait dynamics after rupture: A three-armed randomized controlled trial comparing an individualized treatment algorithm vs. operative or non-operative treatment. Foot Ankle Surg 2023; 29:143-150. [PMID: 36528540 DOI: 10.1016/j.fas.2022.12.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 12/06/2022] [Accepted: 12/12/2022] [Indexed: 12/15/2022]
Abstract
BACKGROUND Individual treatment selection has been proposed as the key to optimized treatment. The purpose was to investigate if treatment selection using the individualized treatment algorithm Copenhagen Achilles Rupture Treatment Algorithm (CARTA) differs between patients treated as usual regarding gait dynamics and tendon elongation. METHODS The patients were randomized to one of three parallel groups: 1) intervention group: participants treated according to CARTA, 2) control group: participants treated non-operatively, 3) control group: participants treated operatively. The primary outcome was ankle peak power during push off during walking at 12 months. RESULTS 156 patients were assessed for eligibility. 21 were allocated to the intervention group, and 20 and 19 to the control groups. The results indicated no statistically significant differences between the intervention group and the control groups. CONCLUSIONS Individualized treatment selection based on CARTA did not demonstrate less affected gait dynamics or less tendon elongation than patients treated as usual.

Abstract
Tendon injuries suffer from a slow healing, often ending up in fibrovascular scar formation, leading to inferior mechanical properties and even re-rupture upon resumption of daily work or sports. Strategies including the application of growth factors have been under view for decades. Insulin-like growth factor-1 (IGF-1) is one of the used growth factors and has been applied to tenocyte in vitro cultures as well as in animal preclinical models and to human patients due to its anabolic and matrix stimulating effects. In this narrative review, we cover the current literature on IGF-1, its mechanism of action, in vitro cell cultures (tenocytes and mesenchymal stem cells), as well as in vivo experiments. We conclude from this overview that IGF-1 is a potent stimulus for improving tendon healing due to its inherent support of cell proliferation, DNA and matrix synthesis, particularly collagen I, which is the main component of tendon tissue. Nevertheless, more in vivo studies have to be performed in order to pave the way for an IGF-1 application in orthopedic clinics.

Abstract
BACKGROUND The best choice of orthosis in the treatment of acute Achilles tendon rupture is still under debate. OBJECTIVE To investigate if choice of orthosis in the first 3 weeks of treatment affected patient reported outcome (Achilles tendon Total Rupture Score (ATRS)), tendon elongation (Achilles Tendon Resting Angle (ATRA) and Heel Rise Height (HRH)) and re-rupture. METHODS Registry study in the Danish Achilles tendon Database. Patients treated with cast and patients treated with walker in the first 3 weeks of treatment were compared using a linear mixed-effects model adjusted for potential confounders. RESULTS 1304 patients were included in the study. No clinically relevant difference was found: Adjusted mean difference (using walker the whole period as reference)(95% CI) ATRS after 1 year = 0.1(-3.0; 4.1), ATRS after 6 months = 2.0(-4.5; 5.8), ATRS after 2 years = 3.0(-0.7; 7.0), HRH difference = 0.6(-6.6; 8.2), ATRA difference = 0.03°(-1.5; 1.6), re-rupture(odds ratio) = 0.812(0.4; 1.61). CONCLUSION Patients treated with cast the first 3 weeks after acute Achilles tendon rupture did not have better treatment outcome than patients treated with walker.

Primary augmentation of percutaneous repair with flexor hallucis longus tendon for Achilles tendon ruptures reduces tendon elongation and may improve functional outcome. Knee Surg Sports Traumatol Arthrosc 2023; 31:94-101.

Abstract
PURPOSE Achilles tendon ruptures (ATR) result in loss of strength and function of the gastrosoleus-Achilles tendon complex, probably because of gradual tendon elongation and calf muscle atrophy, even after surgical repair. Flexor hallucis longus (FHL) augmentation not only reinforces the repair and provides new blood supply to the tendon, but also protects the repair, internally splinting the repaired Achilles tendon, maintaining optimal tension. We prospectively compared the clinical outcomes of patients with acute ATR, managed with either percutaneous repair only or percutaneous repair and FHL augmentation. METHODS Patients with acute ATR undergoing operative management were divided into two groups. Thirty patients underwent percutaneous repair under local anesthesia, and 32 patients underwent percutaneous repair augmented by FHL tendon, harvested through a 3 cm longitudinal posteromedial incision, and transferred to the calcaneus, under epidural anesthesia. All patients were treated by a single surgeon between 2015 and 2019 and were followed prospectively for 24 months. RESULTS The percutaneous only group was younger than the augmented one (35.4 ± 8.0 vs 40.4 ± 6.6 years, p = 0.01). In the augmented group, 25 patients stayed overnight and only 5 were day cases, whereas in the percutaneous only group 4 patients stayed overnight and 28 of them were day cases (p < 0.001). The duration of the procedure was significantly longer in the augmented group (38.9 ± 5.2 vs 13.2 ± 2.2 min, p < 0.001). At 24 months after repair, the Achilles tendon resting angle (ATRA) was better in the augmented group (-0.5 ± 1.7 vs -4.0 ± 2.7, p < 0.001), as was Achilles tendon rupture score (ATRS) (91.7 ± 2.2 vs 89.9 ± 2.4, p = 0.004). Calf circumference of the injured and the non-injured leg did not differ between the groups, as did the time interval to single toe raise and the time interval to walking in tiptoes. Although plantarflexion strength of the operated leg was significantly weaker than the non-operated leg in both groups, the difference in isometric strength of the operated leg between the groups was not significant at 24 months (435 ± 37.9 vs 436 ± 39.7 N, n.s.). CONCLUSION Percutaneous repair and FHL tendon augmentation may have a place in the management of acute Achilles tendon ruptures, reducing tendon elongation and improving functional outcome.

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 Early tensile loading improves material properties of healing Achilles tendon ruptures in animal models and in surgically treated human ruptures. However, the effect of such rehabilitation in patients who are nonsurgically treated remains unknown. HYPOTHESIS In nonsurgically treated Achilles tendon ruptures, early tensile loading would lead to higher elastic modulus 19 weeks after the injury compared with controls. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS Between October 2015 and November 2018, a total of 40 nonsurgically treated patients with acute Achilles tendon rupture were randomized to an early tensile loading (loaded group) or control group. Tantalum bead markers were inserted percutaneously into the tendon stumps 2 weeks after the injury to allow high-precision measurements of callus deformation under mechanical testing. The loaded group used a training pedal twice daily to produce a gradual increase in tensile load during the following 5 weeks. Both groups were allowed full weightbearing in an ankle orthosis and unloaded range of motion exercises. Patients were followed clinically and via roentgen stereophotogrammetric analysis and computed tomography at 7, 19, and 52 weeks after the injury. RESULTS The mean ± standard deviation elastic modulus at 19 weeks was 95.6 ± 38.2 MPa in the loaded group and 108 ± 45.2 MPa in controls (P = .37). The elastic modulus increased in both groups, although it was lower in the loaded group at all time points. Tendon cross-sectional area increased from 7 weeks to 19 weeks, from 231 ± 99.5 to 388 ± 142 mm2 in the loaded group and from 188 ± 65.4 to 335 ± 87.2 mm2 in controls (P < .001 for the effect of time). Cross-sectional area for the loaded group versus controls at 52 weeks was 302 ± 62.4 mm2 versus 252 ± 49.2 mm2, respectively (P = .03). Gap elongation was 7.35 ± 13.9 mm in the loaded group versus 2.86 ± 5.52 mm in controls (P = .27). CONCLUSION Early tensile loading in nonsurgically treated Achilles tendon ruptures did not lead to higher elastic modulus in the healing tendon but altered the structural properties of the tendon via an increased tendon thickness.

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.

Abstract
PURPOSE OF REVIEW Achilles tendon ruptures (ATR) are detrimental to sports performance, and optimal treatment strategy and guidelines on return to play (RTP) remain controversial. This current review investigates the recent literature surrounding nonoperative versus operative management of ATR, clinical outcomes, and operative techniques to allow the athlete a successful return to their respective sport. RECENT FINDINGS The Achilles tendon (AT) is crucial to the athlete, as it is essential for explosive activities such as running and jumping. Athletes that sustain an ATR play in fewer games and perform at a lower level of play compared to age-matched controls. Recent studies also theorize that ATRs occur due to elongation of the tendon with fatigue failure. Biomechanical studies have focused on comparing modes of fixation under dynamic loading to recreate this mechanism. ATRs can be career-ending injuries. Fortunately, the recent incorporation of early weight-bearing and functional rehabilitation programming for non-operative and operative patients alike proves to be beneficial. Especially for those treated nonoperatively, with the incorporation of functional rehabilitation, the risk of re-rupture among non-operative patients is beginning to approach the historical lower risk of re-rupture observed among patients treated operatively. Despite this progress in decreasing risk of re-rupture particularly among non-operative patients, operative managements are associated with unique benefits that may be of particular interest for athletes and active individuals. Recent studies demonstrate that operative intervention improves strength and functional outcomes with more efficacy compared to nonoperative management with rehabilitation. The current literature supports operative intervention in elite athletes to improve performance and shorten the duration to RTP. However, we acknowledge that surgical intervention does have inherent risks. Ultimately, most if not all young and/or high-level athletes with an ATR benefit from surgical repair, but it is crucial to take a stepwise algorithmic approach and consider other factors, which may lead towards nonoperative intervention. These factors include age, chronicity of injury, gap of ATR, social factors, and medical history amongst others in this review.

Current Consensus for Rehabilitation Protocols of the Surgically Repaired Acute Mid-Substance Achilles Rupture: A Systematic Review and Recommendations From the "GAIT" Study Group. J Foot Ankle Surg 2022; 61:855-861. [PMID: 35120805 DOI: 10.1053/j.jfas.2021.12.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/01/2020] [Revised: 07/01/2021] [Accepted: 12/01/2021] [Indexed: 02/03/2023]
Abstract
Surgical repair of acute mid-substance Achilles tendon ruptures is performed in active patients, but the postoperative rehabilitation program is often based on the experience of the surgeon or therapist, rather than on evidence-based protocols. The aim of the study is to establish an evidence-based protocol for rehabilitation. This study is a consensus statement. The "GAIT" study group (German, American, and Italian Tendon), an informal collection of 4 experienced foot and ankle surgeons, met to address the question of what items they felt were important relative to rehabilitate a surgically repaired Achilles tendon acute rupture. Thirty-three statements were formulated. A value of 100% agreement by all the members was set to produce a proposed consensus statement. A value of 80% consensus was set to produce "strong recommendation." A systematic review of the literature was also performed. The GAIT group reach 100% agreement on the average postoperative non-weightbearing for 2.3 weeks, the foot in plantarflexion for the first 4 weeks, avoiding ROM exercises beyond neutral, and both stretching and eccentric exercise, not started before 12 weeks. Concentric bilateral heel raises should be performed after 6 weeks, and the average return to initiate sports, was 24.4 weeks. The use of a 1/8th-1/4th inch heel cushions in daily shoes after 8 weeks, the use of an antigravity treadmill for rehabilitation, and the return to sports based on heel raise repetitions is strongly recommended. Given lack of established verified protocols, the recommendations by our experienced panel should be considered. These proposed consensus statements could be used as a basis for larger controlled trials, and develop best practices.

Abstract
Tendon healing is a complex process involving inflammation, proliferation, and remodeling, eventually achieving a state of hypocellularity and hypovascularity. Currently, few treatments can satisfactorily restore the structure and function of native tendon. Bioactive glass (BG) has been shown to possess immunomodulatory and angiogenic properties. In this study, we investigated whether an injectable hydrogel fabricated of BG and sodium alginate (SA) could be applied to enhance tenogenesis following suture repair of injured tendon. We demonstrated that BG/SA hydrogel significantly accelerated tenogenesis without inducing heterotopic ossification based on histological analysis. The therapeutic effect could attribute to increased angiogenesis and M1 to M2 phenotypic switch of macrophages within 7 days post-surgery. Morphological characterization demonstrated that BG/SA hydrogel partially reverted the pathological changes of Achilles tendon, including increased length and cross-sectional area (CSA). Finally, biomechanical test showed that BG/SA hydrogel significantly improved ultimate load, failure stress, and tensile modulus of the repaired tendon. In conclusion, administration of an injectable BG/SA hydrogel can be a novel and promising therapeutic approach to augment Achilles tendon healing in conjunction with surgical intervention.

Abstract
PURPOSE Operative repair of Achilles tendon rupture may lead to complications, which influence outcome adversely. The aim of this study was to determine the incidence, impact and response to treatment of post-operative adhesions. METHODS From February 2009 to 2021, 248 patients operated on with percutaneous or minimally invasive surgical repair have been prospectively evaluated using the Achilles tendon Total Rupture Score (ATRS) and Heel-Rise Height Index (HRHI), following acute Achilles tendon rupture. RESULTS Fourteen (5.6%) patients were identified as having adhesions. Four patients reported superficial adhesions and ten patients reported a deeper tightness of the tendon. At a mean (SD) of 10.5 (2.3) months following repair, the overall ATRS was at a median (IQR) 65 (44.5-78) points and (HRHI) was mean (SD) 81.5 (13.5)%. Of those deemed to have deep adhesions the antero-posterior diameter of the tendon was at mean (SD) 15.6 (4.6) mm. Open release of superficial adhesions resulted in improved ATRS in all patients. Endoscopic debridement anterior to the Achilles tendon led to alleviation of symptoms of tightness and discomfort from deep adhesions and improved outcome in terms of the ATRS score. At a mean (SD) of 15.9 (3.3)-month follow-up from initial rupture and repair, the patients reported at median (IQR) ATRS scores of 85 (64.8-92.8) points, Tegner level 5 (3-9) and mean (SD) HRHI 86.2 (9.5)%. Patients significantly improved both ATRS and HRHI following release at median (IQR) of 16.5 (- 1.8-29.3) points (p = 0.041) and mean (SD) 5.6 (8.3)% (p = 0.043). CONCLUSIONS The incidence of patient-reported adhesions following minimally invasive repair of Achilles tendon rupture was estimated to be 5.6%. The occurrence of superficial adhesions was associated with a lower outcome scores as well as symptoms of anterior tendon tightness and stiffness were associated with a lower score in most patients. Surgical release of adhesions led to a significant improvement in outcome.

Achilles tendon resting angle is able to detect deficits after an Achilles tendon rupture, but it is not a surrogate for direct measurements of tendon elongation, function or symptoms. Knee Surg Sports Traumatol Arthrosc 2022; 30:4250-4257. [PMID: 36087127 PMCID: PMC9463053 DOI: 10.1007/s00167-022-07142-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Accepted: 08/23/2022] [Indexed: 11/27/2022]
Abstract
PURPOSE The aim of this study was to investigate how the Achilles tendon resting angle (ATRA), an indirect measurement of tendon elongation, correlates with ultrasonography (US) measurements of the Achilles tendon length 6 and 12 months after an acute ATR and relates to other clinical outcome measurements such as heel-rise height, jumping ability and patient-reported outcome measurements (PROMs). METHODS Patients were included following acute Achilles tendon rupture (ATR). Achilles tendon length, ATRA, heel-rise height (HRH), drop countermovement jump (Drop CMJ) and PROMs (Achilles tendon total rupture score (ATRS) and physical activity scale (PAS)) were evaluated 6 and 12 months after injury. Achilles tendon length was evaluated using US, while the ATRA was measured with a goniometer. RESULTS Sixty patients (13 women, 47 men), mean (SD) age 43 (9) years, with an acute ATR undergoing either surgical (35%) or non-surgical (65%) treatment were evaluated. A negative correlation (r = - 0.356, p = 0.010) between relative ATRA and tendon elongation was seen at 12 months after ATR. There were also significant positive correlations at 6 and 12 months between relative ATRA and HRH (r = 0.330, p = 0.011 and r = 0.379, p = 0.004). There were no correlations between ATRA and ATRS or ATRA and Drop CMJ, at either 6 or 12 months after the injury. CONCLUSION In combination with other clinical evaluations such as HRH and US, ATRA could be a clinical tool for indirect measurements of tendon elongation. However, ATRA cannot be recommended as a direct surrogate for US for determining Achilles tendon length. LEVEL OF EVIDENCE III.

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
OBJECTIVES Muscle atrophy is one of the most common problems after Achilles tendon repair. The aim of this study was to evaluate the effect of gastrosoleus muscle atrophy and fatty infiltration on clinical, and functional outcomes after Achilles tendon repair. MATERIAL AND METHODS A total of 46 patients (mean age = 39.3 ± 7.4 years) who underwent open Achilles tendon repair were included in the study. During the clinical evaluation of muscle atrophy, ipsilateral and contralateral calf circumference (CC), maximum heel rise (HR), and ankle range of motion measurements were recorded. Functional outcomes were assessed via The Achilles tendon Total Rupture Score (ATRS), the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, and the Leppilahti score. Muscle volume (MV), cross-sectional area (CSA), and percent of fatty infiltration (FI) were measured via magnetic image resonance. RESULTS The functional outcome scores were excellent: ATRS = 98.1 ± 2.2; AOFAS = 97.3 ± 4.1; Leppilahti score = 95.8 ± 5.1. There were significant differences detected between injured and non-injured legs regarding CC, HR, MV, CSA, and FI. Additionally, there were significant negative correlations between CSA and MV loss with all functional outcome scores. FI was correlated with only the AOFAS ankle-hindfoot score. CONCLUSIONS Significant muscle atrophy was measured after a mean follow-up period of 7.4 (range 2.0-12.6) years post-surgery and negatively correlated with clinical outcomes. CC is an easy and cost-effective measurement method to predict MV during the follow-up of Achilles tendon repairs.

Abstract
Background: Achilles tendon rupture (ATR) is a potentially career-ending injury in professional athletes. Limited information exists regarding return to play (RTP) in professional soccer players after this injury. Purpose: To determine the RTP rate and time in professional soccer players after ATR and to evaluate player performance relative to matched controls. Study Design: Cohort study; Level of evidence, 3. Methods: We evaluated 132 professional soccer players who suffered an ATR between 1999 and 2018. These athletes were matched 2:1 to uninjured controls by position, age, season of injury, seasons played, and height. We collected information on the date of injury, the date of RTP, and player performance metrics (minutes played, games played, goals scored, assists made, and points per game) from official team websites, public injury reports, and press releases. Changes in performance metrics for the 4 years after the season of injury were compared with metrics 1 season before injury. Univariate comparisons were performed using independent-sample, 2-group t tests and Wilcoxon rank-sum tests when normality of distributions was violated. Results: The mean age at ATR was 27.49 ± 4.06 years, and the mean time to RTP was 5.07 ± 2.61 months (18.19 ± 10.96 games). The RTP rate was 71% for the season after injury and 78% for return at any timepoint. Overall, 9% of the injured players experienced a rerupture during the study period. Compared with controls, the injured players played significantly less (-6.77 vs -1.81 games [P < .001] and -560.17 vs -171.17 minutes [P < .05]) and recorded fewer goals (-1.06 vs -0.29 [P < .05]) and assists (-0.76 vs -0.02 [P < .05]) during the season of their Achilles rupture. With the exception of midfielders, there were no significant differences in play time or performance metrics between injured and uninjured players at any postinjury timepoint. Conclusion: Soccer players who suffered an ATR had a 78% RTP rate, with a mean RTP time of 5 months. Injured players played less and demonstrated inferior performance during the season of injury. With the exception of midfielders, players displayed no significant differences in play time or performance during any of the 4 postinjury seasons.

Abstract
PURPOSE To determine the benefits associated with using the fanned out plantaris tendon as a membrane to cover and augment the acute Achilles tendon midportion end-to-end suture repair. METHODS Between 2014 and 2018, 31 (67.4%) patients had plantaris augmented reconstruction and 15 simple end-to-end suture. The clinician filled out the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scale and the patient the Achilles tendon total rupture score (ATRS). Examination included clinical examination, limb symmetry index (LSI) using the heel rise test, and ultrasound determination of cross-sectional area (CSA). RESULTS 80.4% were males, mean age 41 (SD 6.7, range 29-57), of which 82.6% were sports accidents. 39/46 were operated in less than two weeks from injury. 82.6% were available at the two year follow-up. Duration of surgery (62.3 min vs 58, p = 0.45), AOFAS (89.6 vs 88.4, p = 0.61 and 97.2 vs 96.8, p = 0.72), ATRS (86.3 vs 83.8, p = 0.33 and 95.6 vs 93.6, p = 0.12), LSI (60.8% vs 58.75, p = 0.24 and 80.5 vs 79, p = 0.29), CSA (3.39cm2 vs 3.36, p = 0.82 and 2.57 vs 2.59, p = 0.87), return to sport (80% vs 57, p = 0.15 and 84.6 vs 85.7, p = 1.00), and complications at six months and two years were comparable between the two techniques. CONCLUSION Fanned out plantaris augmentation of acute Achilles tendon tears yields excellent and comparable clinical and ultrasonographic results to end-to-end suture at mid-term follow-up.

Abstract
BACKGROUND Elongation of the Achilles tendon after rupture is a frequent complication. The Achilles Tendon Length Measure (ATLM) and the Achilles Tendon Resting Angle (ATRA) are indirect length measures using the resting angle of the ankle. Copenhagen Achilles Length Measure (CALM) is a direct ultrasound measure. The purpose of this study was to examine the construct validity of ATLM and ATRA using CALM as gold standard. METHODS As the three measurements measure slightly different constructs and have different scales a direct comparison was not possible. Instead a mixed linear regression model was performed investigating the three models: CALM-ATRA, CALMATLM and ATRA-ATLM. RESULTS 130 patients were available for analysis. All three regression models demonstrated a statistically significant (p < 0.01) linear relationship and acceptable certainty of the estimates. CONCLUSION ATRA and ATLM were found to have acceptable construct validity when using CALM as gold standard for assessing tendon elongation after an Achilles tendon rupture.

Abstract
The optimal postoperative management of Achilles tendon (AT) rupture remains unknown. The past 2 decades have witnessed a trend toward less rigid immobilization, earlier weightbearing, and accelerated functional rehabilitation postoperatively. The objective of this study was to identify all high-quality studies pertaining to rehabilitation after AT repair and characterize the various rehabilitation protocols that have been described. A systematic review of the English-language literature was performed according to PRISMA guidelines. All included studies represented level 1, 2, or 3 evidence and examined postoperative rehabilitation protocols following the repair of an acute AT rupture. A total of 1187 subjects were included. Surgical technique, rehabilitation protocol, and outcome assessment varied widely between studies. Early postoperative weightbearing with less rigid immobilization appears to accelerate short-term functional recovery. An aggressive rehabilitation program may also be advantageous in the short term, but further studies are needed to determine the long-term effects of these accelerated physical therapy and return-to-play protocols.

Abstract
AIMS The aim of this meta-analysis was to assess the prognosis after early functional rehabilitation or traditional immobilization in patients who underwent operative or nonoperative treatment for rupture of the Achilles tendon. METHODS PubMed, Embase, Web of Science, and Cochrane Library were searched for randomized controlled trials (RCTs) from their inception to 3 June 2020, using keywords related to rupture of the Achilles tendon and rehabilitation. Data extraction was undertaken by independent reviewers and subgroup analyses were performed based on the form of treatment. Risk ratios (RRs) and weighted mean differences (WMDs) (with 95% confidence intervals (CIs)) were used as summary association measures. RESULTS We included 19 trials with a total of 1,758 patients. There was no difference between the re-rupture rate (RR 0.84 (95% CI 0.56 to 1.28); p = 0.423), time to return to work (WMD -1.29 (95% CI -2.63 to 0.05); p = 0.060), and sporting activity (WMD -1.50 (95% CI -4.36 to 1.37); p = 0.306) between the early functional rehabilitation and the traditional immobilization treatment strategies. Early rehabilitation up to 12 weeks yielded significantly better Achilles tendon Total Rupture Scores ((ATRS) WMD 5.11 (95% CI 2.10 to 8.12); p < 0.001). Patients who underwent functional rehabilitation had significantly lower limb symmetry index of heel-rise work ((HRW) WMD -4.19 (95% CI -8.20 to 0.17); p = 0.041) at one year. CONCLUSION Early functional rehabilitation is safe and provides better early function and the same functional outcome in the longer term. Cite this article: Bone Joint J 2021;103-B(6):1021-1030.

Abstract
BACKGROUND The aim of this study was to describe the differences in structural and mechanical properties between operated and non-injured Achilles tendons in senior badminton players who had had Achilles tendon surgery and had returned to play. METHODS Eighteen players (age = 48.9(10.0)years), assigned to the unilateral Achilles tendon rupture group and 177 non-injured players (age = 55.4(9.4)years), assigned to the control group. A Logiq®S8 ultrasound was used to study tendon structure and elastography index values and a Myoton®PRO hand-held myotonometer was used to record the stiffness of the Achilles tendon. FINDINGS In Achilles tendon rupture group, operated tendons showed higher values than non-injured ones in thickness (Operated = 9.03(2.67)mm vs. non-injured = 5.88(0.88)mm; P < 0.001), width (Operated = 18.44(3.20)mm vs. non-injured = 16.80(1.97)mm; P = 0.039), cross sectional area (Operated = 140.33(60.29)mm2 vs. non-injured = 74.40(17.09)mm2; P < 0.001) and elastography index (Operated = 2.05(1.35)A.U. vs. non-injured = 1.47(0.62)A.U.; P = 0.025). The bilateral differences shown by the Achilles tendon rupture group were greater than the bilateral differences shown by the control group for thickness (P < 0.001), width (P = 0.001), cross sectional area (P < 0.001), tone (P = 0.006) and dynamic stiffness (Achilles tendon rupture group = 10.85(23.90)N∙m-1. vs. control group = 0.18(18.83)N∙m-1; P = 0.031). INTERPRETATION Surgery on the Achilles tendon and adaptation to the mobilisation and strength training during rehabilitation could provoke structural and mechanical differences compared to the non-injured tendon. Furthermore, the differences between both Achilles tendons in the Achilles tendon rupture group was higher than the asymmetry observed between dominant and non-dominant Achilles tendons in the control group. In addition, the higher logarithmic decrement values showed by non-injured tendons in the Achilles tendon rupture group could be a tendinous injury risk factor.

Abstract
PURPOSE The purpose of this study was to evaluate concurrent validity of the heel-rise work test performed with use of the heel as a surrogate for the center of body mass. METHODS The study was a validity study performed on a prospective cohort of consecutive patients. Forty-five patients were included in the study. The heel-rise work test estimates the total work performed by repeated heel-rises until fatigue. In this study, the heel-rise work was assessed by the linear encoder and a motion capture system simultaneously for validation. The linear encoder was attached to the patient's heel and reflective marker was attached to the pelvis and heel. Student's paired t-test, linear regression analysis and Bland Altman plots were used to estimate the measurement error of the linear encoder. RESULTS The heel-rise work test overestimated the total work with 21.0% on the injured leg and 24.7% on the non-injured leg. Student's paired t-test showed no difference in measurement error between the limbs (n.s.). The linear regression analysis showed no difference in limb symmetry index between the two methods of heel-rise work estimation (a (slope) = 1.00, R = 0.94, p < 0.0001). CONCLUSION The heel-rise work test performed using the heel as a surrogate for center of body mass overestimates the total work with 21.0-24.7% compared to a gold standard but was able to precisely detect the relative difference between the limbs. The heel marker can be considered a valid measurement device for assessing relative differences between the limbs. CLINICAL RELEVANCE Clinical testing of injuries to the lower body using the heel-rise work test is valid when using the relative difference between the limbs. LEVEL OF EVIDENCE I.

No clinically relevant difference between operative and non-operative treatment in tendon elongation measured with the Achilles tendon resting angle (ATRA) 1 year after acute Achilles tendon rupture.

Abstract
PURPOSE Studies have shown that elongation of the injured Achilles tendon after acute Achilles tendon rupture (ATR) is negatively associated with clinical outcomes. The difference between operative and non-operative treatment on the length of the Achilles tendon is only sparsely investigated. The aim of the study was to investigate if the operative and non-operative treatment of ATR had different effects on tendon elongation. METHODS The study was performed as a registry study in the Danish Achilles tendon database (DADB). The primary outcome of the study was an indirect measure of Achilles tendon length: the Achilles tendon resting angle (ATRA) at 1-year follow-up. The variable of interest was treatment (operative or non-operative). RESULTS From August 2015 to January 2019, 438 patients (154 operatively treated and 284 non-operatively treated) were registered with full baseline data and had their ATRA correctly registered at 1-year follow-up in DADB. The analysis did not show a clinically relevant nor statistically significant difference in ATRA between operative and non-operatively treated patients at 1-year follow-up (mean difference - 1.2°; 95% CI - 2.5; 0.1; n.s) after adjustment for potential confounders. CONCLUSION There were neither clinically relevant nor statistically significant differences in terms of the ATRA at 1-year follow-up between the operative and non-operatively treated patients. This finding suggests that operative treatment does not lead to a clinically relevant reduction in tendon elongation compared to non-operative treatment and it should therefore not be used as an argument in the choice of treatment.

Abstract
The abnormalities on MRI should be correlated with the clinical findings. Higher signal of the Achilles tendon is a common postoperative finding. The fluid signal within the Achilles tendon graft indicates a rupture. Postoperative complications of Haglund’s syndrome should be assessed on MRI. Elongation of the Achilles tendon is seen after surgical or conservative treatment.
The most common disorder affecting the Achilles tendon is midportion tendinopathy. A focal fluid signal indicates microtears, which may progress to partial and complete rupture. Assessment of Achilles tendon healing should be based on tendon morphology and tension rather than structural signal. After nonoperative management or surgical repair of the Achilles tendon, areas of fluid signal is pathologic because it indicates re-rupture. A higher signal in the postoperative Achilles tendon is a common finding and is present for a prolonged period following surgical intervention and needs to be interpreted alongside the clinical appearance.

Abstract
» Surgical decision-making should consider factors to help optimize return to play for athletes with foot and ankle injuries, including injuries to the syndesmosis, the Achilles tendon, the fifth metatarsal, and the Lisfranc complex. Understanding influential factors on return to play may help orthopaedic surgeons counsel athletes and coaches on expectations for a timeline to return to play and performance metrics. » Outcomes after rigid and flexible fixation for syndesmotic injuries are generally favorable. Some data support an earlier return to sport and higher functional scores with flexible fixation, in addition to lower rates of reoperation and a decreased incidence of malreduction, particularly with deltoid repair, if indicated. » Minimally invasive techniques for Achilles tendon repair have been shown to have a decreased risk of wound complications. Athletes undergoing Achilles repair should expect to miss a full season of play to recover. » Athletes with fifth metatarsal fractures have better return-to-play outcomes with surgical management and can expect a high return-to-play rate within approximately 3 months of surgery. » Percutaneous treatment of Lisfranc injuries may expedite return to play relative to open procedures.

Abstract
OBJECTIVES To compare re-rupture rate, functional and quality-of-life outcomes, return to sports and work, complications, and resource use in patients treated non-surgically with different rehabilitation regimens for Achilles tendon rupture. DESIGN Systematic review and meta-analysis. METHODS We performed a systematic literature search in PubMed, Embase, Scopus and the Cochrane Library through May 2020 to identify randomized controlled trials (RCTs) that included patients treated non-surgically for Achilles tendon rupture. All analyses were stratified according to rehabilitation protocols. RESULTS Eight RCTs with a total of 978 patients were included. There was no significant difference about re-rupture rate (P=0.38), return to sports (P=0.85) and work (P=0.33), functional outcome (P=0.34), quality of life (P=0.50), and complication rate (P=0.29) between early weight bearing with functional ankle motion and traditional ankle immobilisation with non-weight bearing. Similarly, no significant difference in re-rupture rate (P=0.88), return to sports (P=0.45) and work (P=0.20), functional outcome (P=0.26), and complication rate (P=0.49) was seen between ankle immobilisation with non-weight bearing and early weight bearing without functional ankle motion. CONCLUSIONS Traditional ankle immobilisation with non-weight bearing was not found to be superior to early weight bearing with or without functional ankle motion for patients treated non-surgically for Achilles tendon rupture. Clinicians may consider early weight bearing in functional brace as a safe and cost-effective alternative to non-weight bearing with plaster casting.

Abstract
Tendon elongation after Achilles tendon (AT) repair is associated with the clinical outcome. Reliable suture techniques are essential to reduce gap formations and to allow early mobilization. Cyclic loading conditions represent the repetitive loading in rehabilitation. The aim of this study was to compare the Kessler stitch and double loop knot stitch (DLKS) in a cyclic loading program focussing on gap formation. Sixteen human cadaveric ATs were transected and sutured using either the Kessler stitch or DLKS (eight matched pairs). The suture-tendon configurations were subjected to cyclic loading and additional ultimate load to failure testing using the Zwick 1446 universal testing machine. Each AT survived cyclic loading, with a mean gap formation less than 5 mm after 1000 cycles. The mechanical properties of the Kessler stitch and DLKS were not significantly different after cyclic loading with a mean displacement of 4.57 mm (± 1.16) for the Kessler stitch and 4.85 mm (± 1.14) for the DLKS (P = .76). There were no significant differences in the ultimate load testing (P = .85). Both bioprotective techniques prevent excessive gaping in cyclic testing when tendon loading is moderate. Our data and those from literature of gap formation in cyclic and ultimate loading allow the conclusion, that early aggressive AT loading after repair (e.g. full weightbearing) overstrain simple as well as complex suture configurations. Initial intraoperative tightening of the knots (preloading) before locking is important to decrease postoperative elongation.

Abstract
OBJECTIVES To (1) describe which resistance exercises are used in the first 8 weeks of treatment for acute Achilles tendon rupture and (2) assess the completeness of reporting of the exercise descriptions. DESIGN Scoping review. LITERATURE SEARCH We searched the MEDLINE, Embase, CINAHL, Cochrane Library, and Physiotherapy Evidence Database (PEDro) databases. STUDY SELECTION CRITERIA Randomized controlled trials, cohort studies, and case series (10 or more participants) that reported using resistance exercise in the immobilization period in the first 8 weeks of treatment for acute Achilles tendon rupture were included. DATA SYNTHESIS Completeness of exercise description was assessed with the Consensus on Exercise Reporting Template (CERT) and the Toigo and Boutellier exercise descriptor framework. RESULTS Thirty-eight studies were included. Fifty-one resistance exercises were extracted and categorized as isometric exercises (n = 20), heel raises (n = 6), strengthening with external resistance (n = 13), or unspecified (n = 12). A median of 8 (interquartile range, 6-10) of a possible 19 CERT items was reported. The amount of items described of the 13 Toigo and and Boutellier exercise descriptors ranged from 0 to 11. CONCLUSION A variety of resistance exercises targeted at the ankle plantar flexors were used as part of early functional rehabilitation after Achilles tendon rupture. However, most studies provided inadequate description of resistance exercise interventions. J Orthop Sports Phys Ther 2020;50(12):681-691. Epub 23 Oct 2020. doi:10.2519/jospt.2020.9463.

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).

Repair within the first 48 h in the treatment of acute Achilles tendon ruptures achieves the best biomechanical and histological outcomes. Knee Surg Sports Traumatol Arthrosc 2020; 28:2788-2797. [PMID: 31119340 DOI: 10.1007/s00167-019-05536-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2019] [Accepted: 05/07/2019] [Indexed: 12/16/2022]
Abstract
PURPOSE To compare the biomechanical and histological properties of Achilles tendons repaired at different time points during the acute injury period. METHODS Thirty-six skeletally mature Sprague-Dawley rats underwent bilateral mid-substance Achilles tenotomy. The Achilles tendons were repaired either in the first 24 h (group 1), 24-48 h (group 2), 48-72 h (group 3), or > 72 h (mean: 120 ± 5.2 h) (group 4) after tenotomy. Six weeks after repair, nine tendons per group were assessed biomechanically and histologically. The Stoll histological scoring system was used for histological examination. The groups were compared with each other and native tendons (control group). The correlations between biomechanical and histological results were analysed. RESULTS There were no significant differences between groups 1, 2 and 3 regarding the mean load to failure; it was significantly lower in group 4. Healed tendons in groups 1, 2 and 3 had significantly greater stiffness than native tendons and group 4 tendons. All healed tendons had a larger cross-sectional area than native tendons. There was no significant difference in tendon length between the groups. There was no significant difference in Young's modulus between the groups; Young's modulus was lower in all the groups than in the control group. Group 1 had significantly higher extracellular matrix organization, cell alignment, cell distribution and nucleus morphology scores and total scores than group 4. Group 1 had significantly higher extracellular matrix organization, cell distribution, vascularization and inflammation scores and total scores than group 3. A significant positive correlation was detected between the maximum load to failure and total histological score. CONCLUSION Repair of acute Achilles tendon rupture within 48 h, and especially in the first 24 h, provides better biomechanical and histological outcomes. In the clinical practice, the data could be used to decrease re-rupture rates, to achieve more anatomical tendon healing and to implement more effective post-operative rehabilitation programme.
