Minimum 24-Month Outcomes of Minimally Invasive Paratenon Protection Repair vs Open Giftbox Repair of Ruptured Achilles Tendon.

The paratenon has been shown to promote Achilles tendon healing, but the evidence supporting the role of paratenon protection technique in Achilles tendon repair is sparse. We retrospectively assessed the results of a paratenon-sparing repair technique vs an open giftbox repair of Achilles tendon ruptures. Patients with Achilles tendon rupture who underwent surgical treatment at our hospital between January 2015 and August 2021 were retrospectively reviewed. Among them, 61 patients underwent surgical repair using the minimally invasive paratenon protection technique (MI group) and 67 patients using the open repair giftbox technique (OR group). The postoperative rehabilitation protocol was identical in both groups. The operation time, complication rate, length and cross-sectional area (CSA) of Achilles tendon, shear wave elastography (SWE), CSA of the calf triceps muscle, isokinetic strength, Achilles tendon Total Rupture Score (ATRS), and the Victorian Institute of Sports Assessment-Achilles (VISA-A) score were compared between the 2 groups. The average follow-up time was 40.0 ± 10.2 months. The operation time and complication rate in the MI group were significantly lower than in the OR group (P < .001, P = .031). The ATRS score (P = .015), VISA-A score (P = .002), isokinetic strength (60 degrees/second: P = .006; 180 degrees/second: P = .036), SWE values (P = .007), and CSA of Achilles tendon (P = .043) in the MI group were significantly higher than the OR group. SWE values were significantly positively correlated with the ATRS score (r = 0.294, P < .001) and the VISA-A score (r = 0.304, P < .001). And a significant negative correlation was found between Achilles tendon extension length and peak torque (60 degrees/second: r = -0.309, P < .001; 180 degrees/second: r = -0.218, P = .013). Compared with the open repair giftbox technique, the minimally invasive paratenon protection technique was associated with likely marginally clinically significant improved clinical outcome scores, greater isokinetic strength, and better mechanical properties of the Achilles tendon.

Is Platelet-rich Plasma Effective in Treating Achilles Tendinopathy? A Meta-analysis of Randomized Clinical Trials.

Several meta-analyses have evaluated the use of platelet-rich plasma (PRP) in the treatment of Achilles tendinopathy. Although they generally did not find PRP to be effective, an updated meta-analysis containing all the available, high-quality randomized trial evidence that addresses the methodological shortcomings identified in earlier meta-analyses needs to be performed. This systematic review and meta-analysis aimed to evaluate the efficacy of PRP in improving (1) pain and function as assessed using the Victorian Institute of Sports Assessment-Achilles (VISA-A) score 3 months, 6 months, and 1 year after treatment and (2) VAS pain scores 3 months after treatment in patients with chronic Achilles tendinopathy. We conducted a systematic search of PubMed, Scopus, Embase, and Cochrane CENTRAL from their inception until June 2024, focusing on randomized clinical trials (RCTs) comparing PRP with placebo or other treatments for Achilles tendinopathy. Our search identified 1289 studies, of which 1262 were excluded after removing duplicates and screening titles and abstracts, leaving 27 studies for detailed review. Six RCTs met the inclusion criteria, encompassing 422 patients, with a predominance of participants who were men. Publication bias was suggested by funnel plot asymmetry, which suggested that, if anything, the results may have overstated the apparent benefit of PRP treatment. Risk of bias was evaluated using the Cochrane Risk of Bias tool for randomized trials, revealing an overall low or unclear risk of bias. The primary outcomes were pain relief and functional improvement, assessed using the VAS, scored 0 to 10, with higher scores representing more severe pain, and VISA-A score, scored 0 to 100, with higher scores representing better pain and function. Heterogeneity was assessed using the Cochran Q test and I2 statistics, and a random-effects model was applied due to substantial heterogeneity. Statistical analyses were performed using Review Manager 5.4 and RStudio, version 764. We found no benefit in terms of VISA-A scores favoring PRP over placebo at 3 months (mean difference 1.7 [95% confidence interval (CI) -1.8 to 5.2]; p = 0.34), 6 months (mean difference 0.5 [95% CI [-8.5 to 9.3]; p = 0.92), or 1 year (mean difference -7.9 [95% CI -27.3 to 11.6]; p = 0.43). PRP did not improve VAS pain scores at 3 months (mean difference -0.22 [95% CI -0.56 to 0.12]; p = 0.21). Sensitivity analyses confirmed these findings. PRP showed no difference compared with stromal vascular fraction and was less effective in the short term compared with high-volume injection. Until future high-quality RCTs show a clear clinical benefit, PRP should not be used to treat Achilles tendinopathy. Our analysis found that PRP does not improve pain or function compared with placebo, and potential publication bias suggests that the apparent benefits may be inflated. Surgeons should be cautious when considering PRP for this condition, and future research should focus on larger trials with standardized protocols to provide more definitive guidance.

Effect of Platelet-Rich Plasma Injection on the Treatment of Achilles Tendinopathy: A Systematic Review and Meta-analysis.

Achilles tendinopathy is a common condition without a reproducible and timely treatment modality. Platelet-rich plasma (PRP) injection has been proposed as an enticing treatment option, but there is no consensus regarding its effectiveness. To pool the available data and evaluate the evidence of the effect of PRP injections on Achilles tendinopathy. Systematic review; Level of evidence, 1. This review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. CINAHL via EBSCOhost, Cochrane Library, and PubMed databases were searched for randomized controlled trials comparing PRP injection with nonoperative treatment, with the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire score or maximal Achilles tendon (AT) thickness on ultrasound as outcome measures. Risk-of-bias assessment was performed of the included studies, and meta-analyses compared differences in outcome measures between PRP injection and control at the short-term (3-month), intermediate-term (6-month), and long-term (12-month) follow-ups. Of 409 publications, 6 publications (N = 422 patients with chronic midportion Achilles tendinopathy) were identified from the literature search. Risk-of-bias assessment revealed 2 studies were low risk, 1 was of some concern, and 3 were high risk of bias. Meta-analysis revealed no significant differences between PRP injection and control at any time point for both VISA-A score (short term: P = .29; intermediate term: P = .42; long term: P = .57) and maximal AT thickness (short term: P = .60; intermediate term: P = .20; long term: P = .55). Our review demonstrated that although recent trends have shown an increasing popularity of PRP injection, no solid evidence has been established. The heterogenicity of the tendinopathy pathology and the PRP injection content and methodology should be controlled by better-designed clinical trials. Further research is needed before it should be recommended as a standard treatment.

Ultrasonographic measurements of gastro-soleus fascia thickness in midportion Achilles tendinopathy: A case-control study

BackgroundThe Achilles tendon is one of the thickest, largest, and strongest tendons in the human body. Biomechanically, the AT represents the conjoint tendon of the triceps surae muscle, placed in series with the plantar fascia (PF) to ensure force transmission from the triceps surae toward the toes during walking, running, and jumping. Commonly encountered in the diagnostic evaluation of heel pain, Achilles tendinopathy (AT) refers to a combination of pathological changes affecting the tendon itself often resulting from excessive repetitive stress and overuse. Nevertheless, increasing evidence demonstrates that structural alterations due to overuse or abnormal patterns of skeletal muscle activity are not necessarily restricted to the muscles or tendons but can also affect the fascial tissue. At the same time, there has been recent discussion regarding the role of the fascial tissue as a potential contributor to the pathophysiological mechanisms of the development of several musculoskeletal disorders including tendinopathies. To the best of our knowledge, ultrasound (US) imaging studies on the fascial structures related to the triceps surae complex, as well as their possible correlation with Achillodynia have never been presented in the current literature. MethodsIn the present study, a comparative US imaging evaluation of textural features of the suro-Achilleo-plantar complex was performed in 14 healthy controls and 14 symptomatic subjects complaining of midportion AT. The thickness of the Achilles tendon, paratenon, intermuscular fascia, and PF has been assessed with US. In addition, both groups underwent the Victorian Institute of Sport Assessment-Achilles (VISA-A), a disease-specific questionnaire that measures the severity of symptoms of AT. Correlations between quantitative ultrasound measures and VISA-A scores were determined through Pearson or Spearman's rho correlations. ResultsOur ultrasonographic findings revealed statistically significant differences (p<0.05) in Achilles tendon and paratenon thicknesses between AT patients and controls. No significant differences were observed between groups in PF at the calcaneal insertion as all mean measures were within the expected range of a normal PF on US imaging. In contrast, in tendinopathic subjects, the deep intermuscular fascia between medial gastrocnemius (MG) and soleus (SOL) muscles is significantly (p<0.01) and considerably thickened compared to those of healthy subjects. Moderate correlations exist between tendon and paratenon thicknesses (r= 0.54, p= 0.04) and between MG-SOL fascia and tendon thicknesses (r= 0.58, p= 0.03). Regarding symptom severity and US morphological findings, the Spearman ρ test showed no correlation. ConclusionsOur data demonstrate that, in symptomatic subjects, US alterations are not restricted to paratenon and intratendinous areas, but also affect upstream structures along the myofascial chain, resulting in thickening of the fascia interposed between MG and SOL muscles. Moreover, positive correlations were found between MG-SOL fascia thickening and abnormalities in AT, paratenon, and symptom severity. Thus, US alterations in the fascial system should be interpreted within the clinical context of patients with AT as they may in turn represent important predictors of subsequent clinical outcomes and could help healthcare professionals and clinicians to refine non-operative treatment strategies and rehabilitation protocols for this disease.

Efficacy of shock wave therapy and ultrasound therapy in non-insertional Achilles tendinopathy: a randomised clinical trial.

Physiotherapists and physicians continue to seek effective conservative treatments for Achilles tendinopathy. This study aimed to subjectively and objectively determine the therapeutic efficacy of radial shock wave therapy (RSWT) and ultrasound therapy in non-insertional Achilles tendinopathy. Thirty-nine patients with non-insertional Achilles tendinopathy were randomly assigned to three experimental groups, i.e., RSWT (group A), ultrasound therapy (group B), and placebo ultrasound (group C) groups. Before the intervention and at weeks 1 and 6 after the treatment, the patients were assessed using the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire and posturographic measurements of step initiation performed on the force platforms under two different conditions (non-perturbed transit and perturbed transit). Six weeks after therapy, all groups exhibited significantly increased VISA-A scores against the measurement at week 1 after therapy. The post-therapy percentage changes in VISA-A scores were significantly greater in group A compared to group B. The three-way ANOVA demonstrated that treatment type affected sway range in the frontal plane and mean velocity of the centre of foot pressure displacements in the sagittal and frontal planes during quiet standing before step initiation. The Bonferroni post-hoc test showed that the means of all those variables were significantly smaller for group A than for group B patients. The three-way ANOVA revealed an effect of the platform arrangement on transit time and double-support period. The Bonferroni post-hoc test revealed statistically longer transit time for the perturbed vs. non-perturbed trials; a reverse relationship was observed for the double-support period. The VISA-A showed that RSWT was significantly more effective than sonotherapy for alleviation of pain intensity as well as function and activity improvement in patients with non-insertional Achilles tendinopathy. Therefore, RSWT therapy can be used in clinical practice by physiotherapists to alleviate the symptoms of non-insertional Achilles tendinopathy. Objective data registered by force platforms during quiet standing before and after step initiation did not prove useful for monitoring the progress of treatment applied to patients with non-insertional Achilles tendinopathy between consecutive therapy interventions.Clinical trial registration:https://anzctr.org.au/Trial/Registration/TrialReview.aspx?ACTRN=12617000860369, identifier (ACTRN12617000860369).

Role of platelet-rich plasma in insertion tendinitis

Background: Platelet-rich plasma (PRP) helps in the treatment of various insertion tendinitis, and the recurrence rate will be low. In this study, we used intralesional injections of autologous PRP for the treatment of insertion tendinitis. Aims and Objectives: Assessment of pain relief following PRP treatment for insertion tendinitis and ascertaining the efficacy of PRP as a treatment option for insertion tendinitis. Materials and Methods: The study was done at Maharani Laxmi Bai Medical College, Jhansi, between January 2021 and June 2022, including 100 patients were applied for the treatment of PRP. We assessed patients before treatment and at three follow-up time points: 2, 4, and 6 months after the end of treatment. During each evaluation, three parameters were noted: Victorian Institute of Sports Assessment- Achilles (VISA-A) score, the Visual Analog Scale, and patient satisfaction according to the roles and Maudsley score. Results: This was a prospective trial by study design conducted on 100 patients, which included 44 patients with plantar fasciitis and 56 patients with tennis elbow. The response to PRP injection in patients with plantar fasciitis was assessed by the VISA-A score. The pre-injection VISA-A score of patients with plantar fasciitis was 56.82 (mean with SD of 18.015), which improved to 65.45 in the 2nd month (mean with SD −18.857), 4th month with 69.77 (mean with SD–19.823), and at 6 months 71.82 (mean with SD–20.829). Statistical analysis with an analysis of variance test gave a P=0.001. In our study, the patients had gradual sequential improvement in VISA-A score throughout the follow-up, with maximum improvement from the pre-injection score were observed in 2 months (65.45 with SD 18.85). Conclusion: Autologous PRP injection is a safe and useful modality of treatment in the treatment of insertion tendinitis.

Endoscopic calcaneal SpeedBridge technique: Decreased postoperative complication rate in insertional achilles tendinopathy

BackgroundAn endoscopic calcaneal SpeedBridge technique was described recently. The primary objective of this study was to report the postoperative complications seen with calcaneal SpeedBridge repair. The secondary objective was to report short- and medium-term functional outcomes. HypothesisPostoperative complications are less common with endoscopic vs. open SpeedBridge suturing. Material and methodsThe endoscopic SpeedBridge technique was used in 9 patients who had insertional Achilles tendinopathy refractory to conservative management. The patients were evaluated at least 24 months after the procedure. Infectious and wound-healing complications were recorded. Visual analogue scale (VAS) scores for pain and patient satisfaction, shoeing difficulties, the European Foot and Ankle Society (EFAS) score, and the Victorian Institute of Sport Assessment-Achilles (VISA-A) score were assessed. ResultsDuring the mean follow-up of 25.3 months, no complications were recorded. The EFAS and VISA-A scores were 37/40 and 91/100, respectively. The mean VAS scores for pain and satisfaction were 1.7/10 and 9.3/10, respectively. No patients reported shoeing difficulties. ConclusionEndoscopic calcaneal SpeedBridge suturing is associated with a lower complication rate compared to the open variant. Clinical outcomes are highly satisfactory in the short and middle terms. Level of evidenceIV; retrospective observational cohort study.

Comparison of Lateral and Central Achilles Tendon-Splitting Approaches in the Treatment of Haglund Deformity.

This study aimed to compare the complications and outcomes of lateral and central Achilles tendon-splitting approaches for the treatment of Haglund syndrome. Patients who underwent surgery for Haglund syndrome between June 2012 and June 2022 were included in the study. Patients undergoing lateral approach surgery were included in group 1, whereas patients undergoing central Achilles tendon-splitting approach surgery were included in group 2. Surgical outcomes of the patients were evaluated using the American Orthopaedic Foot & Ankle Society (AOFAS) ankle hindfoot scale, visual analog pain scale (VAS), and Victorian Institute of Sport Assessment-Achilles (VISAA) scores. In addition, preoperative and final follow-up scores were compared. The study included 66 patients: 32 (14 females, 18 males) underwent surgery using the lateral approach in group 1, whereas in group 2, 34 patients (18 females, 16 males) underwent surgery using the central Achilles tendon-splitting approach. There was a significant statistical difference in the AOFAS, VISAA, and VAS scores between preoperative and final follow-up for both group 1 and group 2 (P < .001, P < .001, P < .001, P < .001, respectively). Group 1 had a small (0.76) relative increase in VAS score compared with group 2 (P = .033). There was no significant difference between the complication rates of group 1 and group 2. In our study, we found the lateral approach and central Achilles tendon-splitting approaches to be safe and effective in the surgical treatment of Haglund syndrome without clinically meaningful differences in outcomes or complication rates.

A Systematic Review Evaluating Diagnosis Methods and Treatment Protocols for Achilles Tendinopathy

Purpose: Diagnosis and treatment protocols for Achilles tendinopathy can be categorized into various groups. However, their effectiveness varies depending on managing and reducing pain. Therefore, this systematic review analyzes and evaluates the diagnosis methods and compares treatment protocols' effectiveness for Achilles tendinopathy. Methods: A systematic review was performed by searching six electronic databases: PubMed, Cochrane Library, Web of Science, Embase, MEDLINE Ovid, and ProQuest, which were searched for articles on the diagnosis and treatment protocols for Achilles tendinopathy. The studies that met the inclusion criteria were evaluated, and appropriate data was extracted. Results: The ten articles that met the inclusion criteria were included in the study. Evidence from the review showed that the Alfredson protocol had a higher pain nd function improvement compared to the Stanish protocol, with a higher VISA-A score in the Alfredson than the Stanish protocol. The findings showed that combining the Alfredson eccentric exercise and Stanish Stretching exercises would significantly improve pain and function for patients with Midportion Achilles tendinopathy. This result showed that both protocols significantly improve pain and function in Achilles tendinopathy patients. Similarly, HSR and ECC showed no significant statistical difference in the VISA-A (Victorian Institute of Sport Assessment-Achilles) scores. Conclusions: HSR is more favorable than ECC, while Alfredson is superior to the Stanish protocol. The VISA-A scores in Alfredson versus Silbernagel and ECC versus HSR did not provide any significant statistical difference between the groups. Alfredson and Silbernagel protocols and ECC and HSR show similar results in reducing pain.

A pilot study exploring the use of hyaluronic acid in treating insertional achilles tendinopathy.

This study explores the use of ultrasound-guided Hyaluronic Acid (HA) injections for Insertional Achilles Tendinopathy (IAT). A cohort of 15 ankles diagnosed with IAT received three weekly ultrasound-guided HA injections. The Victorian Institute of Sport Assessment - Achilles (VISA-A) questionnaire scored the severity of symptoms and functional impairment before treatment, and at one and six months post-treatment. Significant improvement was observed in VISA-A scores post-treatment, rising from an average baseline of 34.8 ± 15.2 (11-63) to 53.6 ± 20.9 (15-77) after one month, and then to 50.7 ± 18.6 (20-75) after six months. No adverse reactions were noted, underscoring the safety of the intervention. The pilot study presents HA injections as a potentially effective treatment for IAT, while interpretation of these findings must take into account the variability in results, indicating a range of patient responses. It encourages further research to confirm these findings and to explore HA's full potential in managing IAT, despite the limitations of a small sample size and lack of control group.

Paper 68: Outcomes following Extracorporeal Shockwave Therapy for chronic Achilles tendinopathy at short to mid-term follow-up

Objectives: The purpose of this retrospective clinical study was to evaluate outcomes following extracorporeal shockwave therapy (ESWT) for the treatment of Achilles tendinopathy. Subgroup analysis was conducted to identify predictors of poor outcomes. Methods: This retrospective cohort study included existing clinical data from 74 patients from a single academic institution. Patients greater than 16 years of old who underwent ESWT for Achilles tendinopathy in the office setting between 3/3/2017 to 8/2/2022 were included. Data collected included: patient demographics, co-morbidities, treatment characteristics, Victorian institute of sports assessment – Achilles (VISA-A) scoring tool, visual analog scale (VAS), magnetic resonance imaging data, return to play (RTP) data and failures were recorded. Failure was defined as no improvement in VISA-A nor VAS scores or surgical intervention. For these data, mean and standard deviation were calculated, and paired samples T-tests and Welch’s T-tests were performed on clinical outcome scores. Results: In total, 74 patients (91 heels) with a mean age of 54.1 ± 14.0 years and BMI of 27.3 ± 4.5 kg/m2 underwent ESWT for Achilles tendinopathy at a mean follow-up of 25.7 ± 15.0 months. Eighteen patients were in the non-insertional Achilles tendinopathy (NAT) cohort and 56 patients were in the insertional Achilles tendinopathy (IAT) cohort. Both NAT and IAT cohorts had a similar improvement in VISA-A score (p=0.365) and VAS scores (p=0.65). A shorter return to play time was found in the NAT cohort (1.1 ± 0.9 months) compared to the IAT cohort (2.6 ± 5.7 months) but this was not statistically significant (p=0.34). There was a higher failure rate in the the IAT cohort (50.0%) than the NAT cohort (38.9%). Patients who received platelet-rich plasma (PRP) had a higher failure rate (61.2%) than those who did not receive PRP (39.6%). In the NAT cohort, the failure rate in females was 0.0%. In the IAT cohort, the failure rate in females was 61.9%. Linear regression analysis found that elevated BMI and MRI severity were associated with worse post-ESWT outcomes. Conclusions: This retrospective study demonstrated a high failure rate at short-term follow-up in patients who underwent ESWT for Achilles tendinopathy. Higher failure rates were found in patients with IAT and those who received intratendinous PRP. Predictors of poor outcomes included elevated BMI and MRI severity. Further studies with larger patient cohorts and a longer follow-up are necessary to determine the role of ESWT in the treatment of Achilles tendinopathy.

Comparison of efficacy of platelet-rich plasma and extracorporeal shock wave for the treatment of chronic insertional Achilles tendinopathy

To compare clinical efficacy of platelet-rich plasma (PRP) and extracorporeal shock wave in treating chronic insertional Achilles tendinopathy. From February 2019 to August 2021, 42 patients with chronic insertional Achilles tendinopathy were selected and divided into PRP group(20 patients, 28 feet) and shock wave group (22 patients, 29 feet). In PRP group, there were 12 males and 8 females, aged 47.00(28.00, 50.75) years old, and the courses of disease ranged 7.00(6.00, 7.00) months;PRP injection was performed in the Achilles tendon stop area of the affected side. In shock wave group, there were 16 males and 6 females, aged 42.00(35.75, 47.25) years old;and the courses of disease was 7.00(6.00, 8.00) months;shock wave was performed in Achilles tendon stop area of the affected side and triceps surae area. Visual analogue scale (VAS) and Victorian Institute of Sport Assessment-Achilles (VISA-A) were applied to evaluate clnical effect before treatment, 1, 3 and 6 months after treatment, and satisfaction of patients was investigated. VAS and VISA-A score in both groups were significantly improved at 1, 3 and 6 months after treatment than before treatment (P<0.05), VAS and VISA-A score in PRP group at 6 months after treatment were significantly higher than those at 1 and 3 months after treatment, and VAS and VISA-A score in shock wave group were lower than those at 1 and 3 months after treatment (P<0.05). There was no significant difference in VAS and VISA-A score between two groups before treatment, 1 and 3 months after treatment(P>0.05), while VAS and VISA-A score in PRP group were better than those in shock wave group at 6 months after treatment(P<0.05), and the satisfaction survey in PRP group was better than that in shock wave group(P<0.05). PRP injection has a good clinical effect on chronic insertional Achilles tendinopathy with high patient satisfaction, and medium-and long-term effect of PRP injection for the treatment of chronic insertional Achilles tendinopathy is better than that of extracorporeal divergent shock wave.

Comparison between primary repair and augmented repair with gastrocnemius turn-down flap for acute Achilles tendon rupture: a retrospective study with minimum 2-year follow-up

BackgroundTo 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.MethodsFrom 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.ResultsIn 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).ConclusionsAugmented 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 evidenceCohort study; Level of evidence, 3.

Evidence-Based High-Loading Tendon Exercise for 12 Weeks Leads to Increased Tendon Stiffness and Cross-Sectional Area in Achilles Tendinopathy: A Controlled Clinical Trial

BackgroundAssuming that the mechanisms inducing adaptation in healthy tendons yield similar responses in tendinopathic tendons, we hypothesized that a high-loading exercise protocol that increases tendon stiffness and cross-sectional area in male healthy Achilles tendons may also induce comparable beneficial adaptations in male tendinopathic Achilles tendons in addition to improving pain and function.ObjectivesWe investigated the effectiveness of high-loading exercise in Achilles tendinopathy in terms of inducing mechanical (tendon stiffness, maximum strain), material (Young’s modulus), morphological (tendon cross-sectional area (CSA)), maximum voluntary isometric plantar flexor strength (MVC) as well as clinical adaptations (Victorian Institute of Sports Assessment—Achilles (VISA-A) score and pain (numerical rating scale (NRS))) as the primary outcomes. As secondary outcomes, drop (DJ) and counter-movement jump (CMJ) height and intratendinous vascularity were assessed.MethodsWe conducted a controlled clinical trial with a 3-month intervention phase. Eligibility criteria were assessed by researchers and medical doctors. Inclusion criteria were male sex, aged between 20 and 55 years, chronic Achilles tendinopathy confirmed by a medical doctor via ultrasound-assisted assessment, and a severity level of less than 80 points on the VISA-A score. Thirty-nine patients were assigned by sequential allocation to one of three parallel arms: a high-loading intervention (training at ~ 90% of the MVC) (n = 15), eccentric exercise (according to the Alfredson protocol) as the standard therapy (n = 15) and passive therapy (n = 14). Parameters were assessed pre- and-post-intervention. Data analysis was blinded.ResultsPrimary outcomes: Plantar flexor MVC, tendon stiffness, mean CSA and maximum tendon strain improved only in the high-loading intervention group by 7.2 ± 9.9% (p = 0.045), 20.1 ± 20.5% (p = 0.049), 8.98 ± 5.8% (p < 0.001) and −12.4 ± 10.3% (p = 0.001), respectively. Stiffness decreased in the passive therapy group (−7.7 ± 21.2%; p = 0.042). There was no change in Young’s modulus in either group (p > 0.05). The VISA-A score increased in all groups on average by 19.8 ± 15.3 points (p < 0.001), while pain (NRS) dropped by −0.55 ± 0.9 points (p < 0.001). Secondary outcomes: CMJ height decreased for all groups (−0.63 ± 4.07 cm; p = 0.005). There was no change in DJ height and vascularity (p > 0.05) in either group.ConclusionDespite an overall clinical improvement, it was exclusively the high-loading intervention that induced significant mechanical and morphological adaptations of the plantar flexor muscle–tendon unit. This might contribute to protecting the tendon from strain-induced injury. Thus, we recommend the high-loading intervention as an effective (alternative) therapeutic protocol in Achilles tendinopathy rehabilitation management in males.Clinical Trials Registration Number: NCT02732782.

The effect of combined Action Observation Therapy with eccentric exercises in the treatment of mid-portion Achilles-tendinopathy: a feasibility pilot randomised controlled trial

BackgroundMid-portion Achilles Tendinopathy (AT) is a common musculoskeletal condition with varying rehabilitation success rates. Despite the prevalence of this condition, a considerable proportion of individuals experience persisting pain and functional deficits. Current treatment approaches bias the biomedical model which emphasises physically treating and loading the tendon. Overall, there is a lack of consideration for the central nervous system that is commonly implicated in chronic injuries. The aim of this pilot study was to explore the feasibility of combining Action Observation Therapy (AOT), a treatment technique which targets central changes and influences motor learning, with eccentric exercises in the treatment of mid-portion AT. AOT involves the observation of movements and is commonly followed by the physical performance of these same movements.MethodologyThis was a double-blinded randomised controlled pilot feasibility study. All participants underwent the 12-week Alfredson eccentric training protocol. The intervention group watched videos of the exercises prior to performing these exercises, whilst the control group watched nature videos before performing the same exercises. Study feasibility was the primary outcome measure, with the Victorian Institute of Sports Assessment- Achilles (VISA-A) selected as the primary clinical outcome measure.ResultsThirty participants were recruited, reflecting a 75% eligibility rate and 100% of eligible participants enrolled in the study. The retention rate at week 12 was 80%. At week six the mean VISA-A score improved by 18.1 (95% CI 10.2–26.0) in the intervention group and 7.7 (95% CI 0.3–14.9) in the control group, and 75% and 33% of participants in the intervention and control group respectively exceeded the minimal clinically important difference (MCID). At week 12 the mean VISA-A score from baseline improved by 22.25 (95% CI 12.52–31.98) in the intervention group and 16.5-(95% CI 8.47–24.53) in the control group, equating to 75% and 58% in each group respectively exceeding the MCID.ConclusionThe positive feasibility outcomes and exploratory data from the clinical outcome measures suggest that a larger scaled RCT is warranted to further investigate the impact of AOT in the rehabilitation of mid-portion AT.Trial registration ISRCTN58161116, first registered on the 23/12/2020.

Clinical Outcomes of Extracorporeal Shock Wave Therapy for Achilles Tendinopathy: an Analysis of Injury Location, Age, and Body Mass Index

Category: Sports; Other Introduction/Purpose: Extracorporeal Shock Wave Therapy (ESWT) is one of the major advances in orthopedics over the last 20 years as a method for orthopedic surgeons to conservatively treat tendon pathologies such as Achilles tendinopathy (AT). Unfortunately, previous studies involve only a small number of cases, relatively short duration of symptoms, and simple measures of pain. The purpose of this study is to evaluate the impact of age, body mass index (BMI), and location of AT (Insertional (IAT) or Non-Insertional (nIAT)) on clinical outcomes and return to sport (RTS) time after ESWT. Methods: This is a retrospective cohort study that included existing clinical data from 40 patients from a single academic institution. Patients greater than 18 years of age who underwent ESWT for Achilles tendinopathy in the office setting between 8/1/2019 to 8/30/2021 were included. Clinical outcomes of patients were evaluated through the self-reported Visual Analogue Scale (VAS) and Victorian Institute of Sport Assessment-Achilles (VISA-A) scores for assessing pain and functional outcomes of Achilles Tendinopathy. Descriptive statistics were used to provide an overview of the patient characteristics, including sex, age, laterality of injury, BMI, duration of symptoms, RTS time, and follow-up. For these data, mean and standard deviation were calculated, and paired samples T-tests and Welch's T-tests were performed on clinical outcome scores. Results: This study included 48 patients (62 heels), with an average age of 50.8+-14.2 years, BMI of 27.3+-5.3, follow-up of 6.41+- 6.9 months, and RTP time of 5.39+-5.3 weeks. Patients with a BMI &lt;25.0 had significantly higher post-operative VISA-A scores (p=0.007) compared to those with a BMI &gt;25.0, and post-operative VAS scores displayed this trend without significance (p=0.07). Patients &lt;=50 years old had significantly higher post-operative VISA-A scores (p=0.02) compared to those &gt;50 years old, and post-operative VAS scores displayed this trend without significance (p=0.1). Pre- and post-operative VISA-A scores, and post- operative VAS scores, were not significantly different between IAT and nIAT cohorts, except for pre-operative VAS scores where nIAT was higher (p=0.03). Additionally, we found significant improvements in pre-operative to post-operative scores for VAS scores for IAT and nIAT cohorts (p&lt;0.0001), as well for VISA-A for the IAT cohort (p=0.008), but no significant improvement in VISA for the nIAT cohort (p=0.119). Conclusion: Increased BMI and age are determinant factors that significantly adversely affect functional scores (VISA-A) in patients with AT treated with ESWT, but no significant differences were found for these risk factors in terms of pain improvement (VAS). Additionally, we found that the nIAT cohort had significantly higher pre-operative pain than IAT, and no significant improvement in VISA-A scores (though there was a trend of functional improvement). This aligns with the fact that the mid- substance of the Achilles tendon is a watershed area with relatively low vascularity compared to the insertional portion, where lower perfusion weakens the healing benefits of ESWT.
