Abstract
BACKGROUND The purpose of the study was to present the results of a new minimally invasive operative method for Achilles tendon (AT) ruptures that could reduce nerve injuries and add no extra cost. METHODS Thirteen patients with acute AT ruptures who were treated with minimally invasive surgery and followed for a minimum of 12 months were included. At the latest follow-up, American Orthopaedic Foot & Ankle Society (AOFAS) score, calf diameters, ability to walk on tiptoe, and ultrasound examination were evaluated. The average age was 42.8 years (range, 31-62 years). Average follow up was 24.5 months (range, 12-34 months). RESULTS AOFAS score was 92.5 (range, 85-100). Average calf diameters on the operated and nonoperated extremities were 38.9 cm (range, 36-44 cm) and 38.9 cm (range, 36-41 cm), respectively. On ultrasound examination, the site of the rupture was found to be 46.2 mm proximal from the calcaneal insertion, and the operated side was found to be significantly thicker than the nonoperated side (P = .008). There was 1 deep vein thrombosis, which recovered without sequelae. There were no wound problems, reruptures, or nerve injuries. CONCLUSIONS This new minimally invasive operative method was successful, showing good functional results and low complication rates. In our experience, the use of 3 continuous polyester sutures was less irritable with 3 knots. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
BACKGROUND Weightbearing in a fixed brace after acute Achilles tendon ruptures does not necessarily lead to mechanical tension in the tendon. Early motion has a positive effect on the clinical outcome, but it is not clear if this is because of effects on tendon strength or unspecific effects. The aim of this study was to examine if tensional loading leads to an improvement in the mechanical properties of the healing Achilles tendon. HYPOTHESIS The elastic modulus of the tendon callus is increased by early tensional loading. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS Thirty-five patients with an acute Achilles tendon rupture were recruited consecutively. They underwent surgery with a single suture and received metal markers in the distal and proximal parts of the tendon. After surgery, the patients were randomized to either cast immobilization for 7 weeks or tensional loading. The latter group wore a cast for 2 weeks and then a removable foam walker boot for 5 weeks. They were instructed to remove the boot twice daily and push a special training pedal to produce a predetermined, gradually increasing tensional load on the healing tendon. At 7, 19, and 52 weeks postoperatively, the patients were investigated with roentgen stereophotogrammetric analysis under different loading conditions and computed tomography. The collected data allowed calculation of the modulus of elasticity. At 52 weeks, the clinical outcome was also examined using the Achilles tendon Total Rupture Score (ATRS) and the heel-raise index. RESULTS The elastic modulus at 19 and 52 weeks was higher in the tensional loading group. There was no significant difference in the ATRS or heel-raise index at 52 weeks. As in previous studies, there was a significant correlation between the modulus at 7 weeks and the heel-raise index at 52 weeks. There were no signs of tendon elongation. CONCLUSION Early tensional loading improves the mechanical properties of the healing Achilles tendon.

Abstract
OBJECTIVES Acute Achilles tendon ruptures are common among highly active people. Recently published studies have provided increasing evidence to support non-surgical treatment. This study aimed to assess the incidence trends of surgically treated, acute Achilles tendon ruptures. Our hypothesis, based on the recent literature showing no difference in functional results between surgical and non-surgical treatment, was that the incidence of surgery would be declining. METHODS We conducted a nationwide hospital register-based study. All patients 18 years of age or older with a diagnosis of acute Achilles tendon injury, and treated with Achilles tendon repair from 1987 to 2011 in Finland were included in the study. RESULTS During the 25-year study period in Finland, a total of 15,252 patients received surgical treatment for an acute Achilles tendon rupture. The incidence of surgical treatment of acute Achilles tendon rupture in men was 11.1/100,000 person-years in 1987 and 20.5/100,000 person-years in 2011. The corresponding figures in women were 2.5/100,000 person-years in 1987 and 4.2/100,000 person-years in 2011. The highest rates occurred in 2008 in men and 2007 in women, and since then the decrease has been 42% in men and 55% in women. CONCLUSIONS During the past few years, the rate of surgically treated acute Achilles tendon ruptures has declined remarkably. The findings of the present study indicate that orthopaedic surgeons have chosen more often non-surgical treatment option for acute Achilles ruptures. This can be considered as an example, how high-quality scientific evidence can lead to a rapid change in clinical practice.

Abstract
Background: Precise long-term assessment of movement and physical function following Achilles tendon rupture is required for the development and evaluation of treatment, including different regimens of physical therapy. Purpose: To assess intermediate-term (<10 years by conventional thinking) objective measures of physical function following Achilles tendon rupture treated nonsurgically and to compare these with self-reported measures of physical function. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Two to 5 years after Achilles tendon rupture, 9 women and 43 men (mean age, 49.2 years; range, 26-68 years) were assessed by physical examination, performance of 1-legged jumps, and 3-dimensional gait analysis (including calculation of muscle work). Self-reported scores for foot function (Achilles tendon rupture score) and level of physical activity were collected. Twenty age- and sex-matched controls were assessed in the same manner. Results: Physical examination of patients with the knee extended revealed 11.1° of dorsiflexion on the injured side and 9.2° on the uninjured side (P = .020), indicating gastrocnemius muscle lengthening. The 1-legged jump distance was shorter on the injured side (89.5 vs 96.2 cm; P < .001). Gait analysis showed higher peak dorsiflexion (14.3° vs 13.3°; P = .016) and lower concentric (positive) plantar flexor work (16.6 vs 19.9 J/kg; P = .001) in the ankle on the uninjured side. At the same time, eccentric (negative) dorsiflexor work was higher on the injured side (13.2 vs 11.9 J/kg; P = .010). Self-perceived foot function and physical activity were lower in patients than in healthy controls (mean Achilles tendon rupture score, 78.6 and 99.8, respectively). Conclusion: Nonsurgically treated patients with Achilles tendon rupture showed signs of both anatomic and functional lengthening of the tendon. Attenuated muscle strength and function were present during walking as long as 2 to 5 years after rupture, as determined by 3-dimensional gait analysis. More extensive future studies involving patients having both surgical and nonsurgical treatment could provide additional valuable information.

Abstract
The best treatment of acute Achilles tendon rupture remains debated. Patient-reported outcome measures have become cornerstones in treatment evaluations. The Achilles tendon total rupture score (ATRS) has been developed for this purpose but requires additional validation. The purpose of the present study was to validate a Danish translation of the ATRS. The ATRS was translated into Danish according to internationally adopted standards. Of 142 patients, 90 with previous rupture of the Achilles tendon participated in the validity study and 52 in the reliability study. The ATRS showed moderately strong correlations with the physical subscores of the Medical Outcomes Study 36-item Short-Form Health Survey (r = .70 to .75; p < .0001) and Victorian Institute of Sports Assessment-Achilles questionnaire (r = .71; p < .0001). Test-retest of the ATRS showed no significant difference in the mean (2.41; p = .07). The limits of agreement were ±18.53. A strong correlation was found between test and retest (intercorrelation coefficient .908); the standard error of measurement was 6.7, and the minimal detectable change was 18.5. The Danish version of the ATRS showed moderately strong criterion validity. For study and follow-up purposes, the ATRS seems reliable for comparisons of groups of patients. Its usability is limited for repeated assessment of individual patients. The development of analysis guidelines would be desirable.

Abstract
Background: Randomized studies have so far failed to show a difference in outcome between operative and nonoperative management of Achilles tendon rupture, provided that no rerupture occurs. Percutaneous Achilles repair has been suggested to result in superior patient satisfaction compared with open repair in patients with an acute Achilles tendon rupture, but there are no outcome data available with validated methods describing the progression of recovery during the first year. Purpose: To evaluate the outcome of patients with a ruptured Achilles tendon, managed by percutaneous repair, during the first year following repair with a valid, reliable, and responsive outcome measure. Furthermore, the effects of time between injury and surgery, age, and complications on outcome were also evaluated. Study design: Case series. Methods: A total of 73 patients (60 males and 13 females) with a mean age of 45.5 years were included. Patient age, length of time between injury and surgery, and complications were documented. Patients were evaluated using the Achilles tendon Total Rupture Score (ATRS) at 3, 6, 9, and 12 months following repair. Results: The median ATRS results at 3, 6, 9, and 12 months were 42.5, 73, 83, and 89, respectively. The number of patients who reported excellent or good scores (ATRS >84) at 3, 6, 9, and 12 months were 3%, 36%, 57%, and 69%, respectively. There were no significant differences in outcome at each time point for those patients undergoing early (≤48 hours) compared with late surgery or between those <65 and those >65 years of age. The complication rate was 13.5%. Patients who had a complication had a lower ATRS result at 3 months following surgery, but there were no differences after that time point. Conclusion: The patients in the present study reported marked improvement in function between 3 and 6 months following surgery, with continuing but less steep improvement up to 1 year following surgery. The presence of a complication other than rerupture did not affect the end-stage outcome but did affect that at 3 months following surgery. Clinical Relevance: This study demonstrates improving scores with time over the first year following surgery, against which other treatment methods can be compared.

Abstract
PURPOSE The Achilles tendon Total Rupture Score (ATRS) was developed because of the need for a reliable, valid and sensitive instrument to evaluate symptoms and their effects on physical activity in patients following either conservative or surgical management of an Achilles tendon rupture. Prior to using the score in larger randomized trial in an English-speaking population, we decided to perform reliability, validity and responsiveness evaluations of the English version of the ATRS. Even though the score was published in English, the actual English version has not be validated and compared to the results of the Swedish version. METHODS From 2009 to 2010, all patients who received treatment for Achilles tendon rupture were followed up using the English version of the ATRS. Patients were asked to complete the score at 3, 6 and 12 months following treatment for Achilles tendon rupture. The ATRS was completed on arrival in the outpatient clinic and again following consultation. RESULTS The outcomes of 49 (13 female and 36 male) patients were assessed. The mean (SD) age was 49 (12) years, and 27 patients had treatment for a left-sided rupture, 22 the right. All patients received treatment for ruptured Achilles tendons: 38 acute percutaneous repair, 1 open repair, 5 an Achilles tendon reconstruction using a Peroneus Brevis tendon transfer for delayed presentation, 1 gracilis augmented repair for re-rupture and 4 non-operative treatment for mid-portion rupture. The English version of ATRS was shown to have overall excellent reliability (ICC = 0.986). There was no significant difference between the results with the English version and the Swedish version when compared at the 6-month- or 12-month (n.s.) follow-up appointments. The effect size was 0.93. The minimal detectable change was 6.75 points. CONCLUSIONS The ATRS was culturally adapted to English and shown to be a reliable, valid and responsive method of testing functional outcome following an Achilles tendon rupture.

Abstract
PURPOSE Recent meta-analyses have shown reduced re-rupture rates for the surgical management of Achilles ruptures. However, percutaneous repair has been demonstrated to lead to improved function and patient satisfaction but greater complications than open repair. In the current economic climate, it is reasonable to consider the financial cost of rupture management for both the patient and the provider. The cost-effectiveness of operative treatment of ruptures of the Achilles tendon was determined based upon theatre occupancy, clinic attendance and cast changes, operative complications and functional assessment score. METHODS The cost-effectiveness of the surgical management of Achilles tendon ruptures between 2005 and 2011 in our unit was audited by comparing 49 patients receiving percutaneous repair to 35 patients whom had open repairs. RESULTS There was no significant difference in complications between the two surgical techniques: (Open vs. Percutaneous) overall rates 14.3 versus 10.4 %: infection; 2.7 versus 2.0 %, transient sural nerve damage: 5.6 versus 8.1 %, wound breakdown: 2.8 versus 0.0 %, re-rupture: 2.8 versus 2.0 %. Achilles Total Rupture Scores (ATRS) were comparable [Open 89 (65-100) at 49 months vs. Percutaneous 88.8 (33-100) at 12 months (n.s.)]. Theatre occupancy (P < 0.00) and hospital stay (P < 0.00) were significantly longer with open repair [43 min (26-70) and 2.9 days (0-4)] compared to percutaneous repair [15 min (12-43) and 1.2 days (0-2)]. Excluding the costs of running the operating theatre, we have estimated the costs of surgery for open repair to be £ 935 and percutaneous repair to be £ 574. CONCLUSIONS This study suggests that percutaneous repair of the Achilles tendon resulted in reduced costs and yet had comparable outcome and complications rates to open repair in surgical management of the Achilles tendon. Percutaneous repair should be considered as the primary method of cost-effective surgical management of Achilles tendon rupture.

Abstract
The best treatment of acute Achilles tendon rupture has been discussed for decades. During the past half decade, evidence has increased in favor of nonoperative treatment and dynamic and weightbearing rehabilitation. We hypothesized that the treatment strategies would show great variation and that adherence to evidence-based recommendations would not be as good as desired. The purpose of the present study was to investigate how acute Achilles tendon rupture is treated in Scandinavia. A questionnaire was distributed to all orthopedic departments treating acute Achilles tendon ruptures in Denmark, Sweden, Norway, and Finland. The questionnaire was returned by 138 of 148 departments (response rate 93%). Two-way tables with Fisher's exact test were used for statistical analysis. In Denmark, Norway, Sweden, and Finland, 19 of 23 (83%), 44 of 48 (92%), 26 of 40 (65%), and 8 of 27 (30%) departments recommended surgical treatment (p < .001). Dynamic rehabilitation was used significantly less often in Denmark (5 of 23 [22%]), Norway (17 of 45 [38%]), and Sweden (11 of 40 [28%]) than in Finland (15 of 26 [58%]; p = .015). A significant difference was found among the countries in the educational level of the performing surgeons (p < .001). Surgical treatment was the treatment of choice in Danish, Norwegian, and Swedish hospitals regardless of the increasing evidence favoring nonoperative treatment. Although increasing evidence has favored dynamic rehabilitation, it has gained limited use across Scandinavia. Weightbearing was used in most hospitals. Surgery was performed by junior surgeons in most hospitals across Scandinavia. Treatment algorithms showed considerable variation and often did not adhere to the clinical evidence.

Abstract
Whether Achilles tendon rupture benefits from surgery or conservative treatment remains controversial. Moreover, the outcome can be influenced by the rehabilitation protocol. The goal of the present meta-analysis was to compare the rerupture rate after surgical repair of the Achilles tendon followed by weightbearing within 4 weeks versus conservative treatment with weightbearing within 4 weeks. In addition, a secondary analysis was performed to compare the rerupture rates in patients who started weightbearing after 4 weeks. Seven randomized controlled trials published from 2001 to 2012, with 576 adult patients, were included. The primary outcome measure was the rerupture rate. The secondary outcomes were minor and major complications other than rerupture. In the early weightbearing group, 7 of 182 operatively treated patients (4%) experienced rerupture versus 21 of 176 of the conservatively treated patients (12%). A secondary analysis of the patients treated with late weightbearing showed a rerupture rate of 6% (7 of 108) for operatively treated patients versus 10% (11 of 110) for conservatively treated patients. The differences concerning the rerupture rate in both groups were not statistically significant. No differences were found in the occurrence of minor or major complications after early weightbearing in both patient groups. In conclusion, we found no difference in the rerupture rate between the surgically and nonsurgically treated patients followed by early weightbearing. Weightbearing after 4 weeks also resulted in no differences in the rupture rate in the surgical versus conservatively treated patients. However, surgical treatment was associated with a twofold greater complication rate than conservative treatment.

Abstract
The Achilles tendon (AT) is the most frequently ruptured tendon in the human body yet the aetiology remains poorly understood. Despite the extensively published literature, controversy still surrounds the optimum treatment of complete rupture. Both non-operative management and percutaneous repair are attractive alternatives to open surgery, which carries the highest complication and cost profile. However, the lack of a universally accepted scoring system has limited any evaluation of treatment options. A typical UK district general hospital treats approximately 3 cases of AT rupture a month. It is therefore important for orthopaedic surgeons to correctly diagnose and treat these injuries with respect to the best current evidence-based practice. In this review article, we discuss the relevant pathophysiology and diagnosis of the ruptured AT and summarize the current evidence for treatment.

Abstract
BACKGROUND Surgical repair is a common method of treatment of acute Achilles rupture in North America because, despite a higher risk of overall complications, it has been believed to offer a reduced risk of rerupture. However, more recent trials, particularly those using functional bracing with early range of motion, have challenged this belief. The aim of this meta-analysis was to compare surgical treatment and conservative treatment with regard to the rerupture rate, the overall rate of other complications, return to work, calf circumference, and functional outcomes, as well as to examine the effects of early range of motion on the rerupture rate. METHODS A literature search, data extraction, and quality assessment were conducted by two independent reviewers. Publication bias was assessed with use of the Egger and Begg tests. Heterogeneity was assessed with use of the I2 test, and fixed or random-effect models were used accordingly. Pooled results were expressed as risk ratios, risk differences, and weighted or standardized mean differences, as appropriate. Meta-regression was employed to identify causes of heterogeneity. Subgroup analysis was performed to assess the effect of early range of motion. RESULTS Ten studies met the inclusion criteria. If functional rehabilitation with early range of motion was employed, rerupture rates were equal for surgical and nonsurgical patients (risk difference = 1.7%, p = 0.45). If such early range of motion was not employed, the absolute risk reduction achieved by surgery was 8.8% (p = 0.001 in favor of surgery). Surgery was associated with an absolute risk increase of 15.8% (p = 0.016 in favor of nonoperative management) for complications other than rerupture. Surgical patients returned to work 19.16 days sooner (p = 0.0014). There was no significant difference between the two treatments with regard to calf circumference (p = 0.357), strength (p = 0.806), or functional outcomes (p = 0.226). CONCLUSIONS The results of the meta-analysis demonstrate that conservative treatment should be considered at centers using functional rehabilitation. This resulted in rerupture rates similar to those for surgical treatment while offering the advantage of a decrease in other complications. Surgical repair should be preferred at centers that do not employ early-range-of-motion protocols as it decreased the rerupture risk in such patients.

Abstract
BACKGROUND Despite several randomized controlled trials comparing operative to nonoperative management of Achilles tendon ruptures, the optimal management of this condition remains the subject of significant debate. Rerupture is a known complication, but most level I studies have not shown a significant difference in the incidence of reruptures when comparing operative to nonoperative management. PURPOSE The goal of this systematic review was to identify all randomized controlled trials comparing operative and nonoperative management of Achilles tendon ruptures and to meta-analyze the data with reruptures being the primary outcome. Secondary outcomes including strength, time to return to work, and other complications were analyzed as well. STUDY DESIGN Meta-analysis. METHODS We searched multiple online databases to identify English-language, prospective randomized controlled trials comparing open surgical repair of acute Achilles tendon ruptures to nonoperative management. Rerupture was our primary outcome. Secondary outcomes included strength, time to return to work, deep infections, sural nerve sensory disturbances, noncosmetic scar complaints, and deep venous thrombosis. Coleman methodology scores were calculated for each included study. Data were extracted from all qualifying articles and, when appropriate, pooled and meta-analyzed. RESULTS Seven level I trials involving 677 patients met inclusion criteria. Coleman scores were 95, 95, 95, 89, 78, 97, and 92. Open repair was associated with a significantly lower rerupture rate compared with nonoperative treatment (3.6% vs 8.8%; odds ratio, 0.425; 95% confidence interval, 0.222-0.815). The incidence of deep infections was significantly higher for patients treated with surgery (P = .0113). The incidences of noncosmetic scar complaints and sural nerve sensory disturbances were also significantly higher in patients treated with surgery (P < .001 for each). Strength measurements were not standardized and therefore could not be meta-analyzed. CONCLUSION Open surgical repair of acute Achilles tendon ruptures significantly reduces the risk of reruptures when compared with nonoperative management. Several other complications, which are clearly avoided with nonoperative treatment, occur with a significantly higher incidence when surgical repair is performed. The available literature makes it difficult to compare the return of strength in the involved lower extremity after operative or nonoperative management. Future studies may focus on testing strength in a more functional and reproducible manner than isokinetic testing.

Abstract
The real-time estimation of muscle forces could be a very valuable tool for rehabilitation. By seeing how much muscle force is being produced during rehabilitation, therapists know whether they are working within safe limits in their therapies and patients know if they are producing enough force to expect improvement. This is especially true for rehabilitation of Achilles tendon ruptures where, out of fear of overloading and causing a re-rupture, minimal therapy is typically done for eight weeks post-surgery despite animal studies that show that low-level loading is beneficial. To address this need, we have developed a biomechanical model that allows for the real-time estimation of forces in the triceps surae muscle and Achilles tendon. Forces are estimated using a Hill-type muscle model. To account for differences in neuromuscular control of each subject, the model used EMGs as input. To make this clinically useful, joint angles were measured using electrogoniometers. A dynamometer was used to measure joint moments during the model calibration stage, but was not required during real-time studies. The model accounts for the force-length and force-velocity properties of muscles, and other parameters such as tendon slack length and optimal fiber length. Additional parameters, such as pennation angle and moment arm of each muscle in the model, vary as functions of joint angle. In this paper, the model is presented and it application is demonstrated in two subjects: one with a healthy Achilles tendon and a second six months post Achilles tendon rupture and repair.

Abstract
BACKGROUND Whether an Achilles tendon rupture is treated surgically or not, complications such as muscle weakness, decrease in heel-rise height, and gait abnormalities persist after injury. PURPOSE The purpose of this study was to evaluate if side-to-side differences in maximal heel-rise height can be explained by differences in Achilles tendon length. STUDY DESIGN Case series; level of evidence, 4. METHOD Eight patients (mean [SD] age of 46 [13] years) with acute Achilles tendon rupture and 10 healthy subjects (mean [SD] age of 28 [8] years) were included in the study. Heel-rise height, Achilles tendon length, and patient-reported outcome were measured 3, 6, and 12 months after injury. Achilles tendon length was evaluated using motion analysis and ultrasound imaging. RESULTS The Achilles tendon length test-retest reliability (intraclass correlation coefficient = 0.97) was excellent. For the healthy subjects, there were no side-to-side differences in tendon length and heel-rise height. Patients with Achilles tendon ruptures had significant differences between the injured and uninjured side for both tendon length (mean [SD] difference, 2.6-3.1 [1.2-1.4] cm, P = .017-.028) and heel-rise height (mean [SD] difference, -4.1 to -6.1 [1.7-1.8] cm, P = .012-.028). There were significant negative correlations (r = -0.943, P = .002, and r = -0.738, P = .037) between the side-to-side difference in heel-rise height and Achilles tendon length at the 6- and 12-month evaluations, respectively. CONCLUSION The side-to-side difference found in maximal heel-rise height can be explained by a difference in Achilles tendon length in patients recovering from an Achilles tendon rupture. Minimizing tendon elongation appears to be an important treatment goal when aiming for full return of function.

Abstract
This study evaluated the short-term recovery of function after an acute Achilles tendon rupture, measured by a single-legged heel-rise test, with main emphasis on the relation to the patient-reported outcomes and fear of physical activity and movement (kinesiophobia). Eighty-one patients treated surgically or non-surgically with early active rehabilitation after Achilles tendon rupture were included in the study. Patient's ability to perform a single-legged heel-rise, physical activity level, patient-reported symptoms, general health, and kinesiophobia was evaluated 12 weeks after the injury. The heel-rise test showed that 40 out of 81 (49%) patients were unable to perform a single heel-rise 12 weeks after the injury. We found that patients who were able to perform a heel-rise were significantly younger, more often of male gender, reported a lesser degree of symptoms, and also had a higher degree of physical activity at 12 weeks. There was also a significant negative correlation between kinesiophobia and all the patient-reported outcomes and the physical activity level. The heel-rise ability appears to be an important early achievement and reflects the general level of healing, which influences patient-reported outcome and physical activity. Future treatment protocols focusing on regaining strength early after the injury therefore seem to be of great importance. Kinesiophobia needs to be addressed early during the rehabilitation process.

Abstract
STUDY DESIGN Case report. BACKGROUND The Achilles tendon is the most frequently ruptured tendon, and the incidence of Achilles tendon rupture has increased in the last decade. The rupture generally occurs without any preceding warning signs, and therefore preinjury data are seldom available. This case represents a unique opportunity to compare preinjury running mechanics with postinjury evaluation in a patient with an Achilles tendon rupture. CASE DESCRIPTION A 23-year-old female sustained a right complete Achilles tendon rupture while playing soccer. Running mechanics data were collected preinjury, as she was a healthy participant in a study on running analysis. In addition, patient-reported symptoms, physical activity level, strength, ankle range of motion, heel-rise ability, Achilles tendon length, and running kinetics were evaluated 1 year after surgical repair. OUTCOMES During running, greater ankle dorsiflexion and eversion and rearfoot abduction were noted on the involved side postinjury when compared to preinjury data. In addition, postinjury, the magnitude of all kinetics data was lower on the involved limb when compared to the uninvolved limb. The involved side displayed differences in strength, ankle range of motion, heel rise, and tendon length when compared to the uninvolved side 1 year after injury. DISCUSSION Despite a return to normal running routine and reports of only minor limitations with running, considerable changes were noted in running biomechanics 1 year after injury. Calf muscle weakness and Achilles tendon elongation were also found when comparing the involved and uninvolved sides.

Abstract
Minimally invasive repair of acute traumatic ruptures of the tendo Achillis may produce lower complications compared to open repair. Twenty-three active patients underwent percutaneous repair of an acute rupture of the tendo Achillis. Post-operatively, the ATRS score was administered to assess the functional status. The maximum calf circumference, isometric plantar flexion strength of the gastrocsoleus muscle complex, ankle dorsiflexion, and return to sport activity were assessed in all patients at an average post-operative follow-up of 25.7 months. At the last follow-up, the mean Achilles tendon total rupture score (ATRS) score was 84 (range: 53-99). Ankle dorsiflexion and maximum calf circumference on the operated limb were not significantly different compared to the uninjured side. The isometric strength on the operated limb was significantly lower (P=0.04) compared to the contralateral side. Of the 21 (90%) patients participating in sports activities, 16 (80%) had returned to their pre-operative sport, 2 changed to lower activity, and 1 increased his performance. This percutaneous technique provides satisfactory outcome in terms of strength and return to pre-operative level of sport activity.

Abstract
PURPOSE The aim of this study was to evaluate, in a meta-analysis, the clinical effectiveness of operative treatment for acute Achilles tendon rupture (AATR) compared with nonoperative treatment. METHODS We systematically searched six electronic databases (Medline, Embase, Clinical Ovid, BIOSIS and Cochrane registry of controlled clinical trials) to identify randomised controlled trials (RCTs) in which operative treatment was compared with nonoperative treatment for AATR from 1980 to 2011. Trial quality was assessed using the modified Jadad scale. The data was using fixed-effects and random-effects models with mean differences and risk ratios for continuous and dichotomous variables, respectively. RESULTS Ten RCTs with a total of 894 patients were screened. The results showed that operative was superior to nonoperative treatment regarding lower risk of re-rupture (P = 0.002) and shorter time for sick leave (P = 0.009) but inferior to nonoperative treatment regarding complication risks (P = 0.004). No significant difference was identified between the two methods regarding the number of patients who successfully returned to pre-injury sports (P = 0.30). Subgroup analyses revealed significant differences in relation to scar adhesion (P < 0.00001), superficial infection (P = 0.05), and sensibility disturbance (P = 0.0003). However, no significant differences were found between the two interventions in relation to deep infection (P = 0.22), deep vein thrombosis (DVT) (P = 0.14), and extreme Achilles tendon lengthening (P = 0.31). Little consensus was obtained in the functional recovery from current trials as a result of an inconsistent assessment system. CONCLUSIONS Compared with conservative treatment, operative treatment can effectively reduce the risk of re-rupture but increase the probability of complications. The increased complication risk may be associated with open repair surgery. However, no sufficient evidence is available from current studies to support the belief that operation may lead to better functional recovery.

Abstract
Rupture of the Achilles tendon is a considerable cause of morbidity with reduced function following injury. Recent studies have shown little difference in outcome between the techniques of open and non-operative treatment using an early active rehabilitation programme. Meta-analyses have shown that non-operative management has increased risk of re-rupture whereas surgical intervention has risks of complications related to the wound and iatrogenic nerve injury. Minimally invasive surgery has been adopted as a way of reducing infections rates and wound breakdown however avoiding iatrogenic nerve injury must be considered. We discuss the techniques and outcomes of percutaneous and minimally invasive repairs of the Achilles tendon.

Abstract
A total of 80 patients with an acute rupture of tendo Achillis were randomised to operative repair using an open technique (39 patients) or non-operative treatment in a cast (41 patients). Patients were followed up for one year. Outcome measures included clinical complications, range of movement of the ankle, the Short Musculoskeletal Function Assessment (SMFA), and muscle function dynamometry evaluating dorsiflexion and plantar flexion of the ankle. The primary outcome measure was muscle dynamometry. Re-rupture occurred in two of 37 patients (5%) in the operative group and four of 39 (10%) in the non-operative group, which was not statistically significant (p = 0.68). There was a slightly greater range of plantar flexion and dorsiflexion of the ankle in the operative group at three months which was not statistically significant, but at four and six months the range of dorsiflexion was better in the non-operative group, although this did not reach statistically significance either. After 12 weeks the peak torque difference of plantar flexion compared with the normal side was less in the operative than the non-operative group (47% vs 61%, respectively, p < 0.005). The difference declined to 26% and 30% at 26 weeks and 20% and 25% at 52 weeks, respectively. The difference in dorsiflexion peak torque from the normal side was less than 10% by 26 weeks in both groups, with no significant differences. The mean SMFA scores were significantly better in the operative group than the non-operative group at three months (15 vs 20, respectively, p < 0.03). No significant differences were observed after this, and at one year the scores were similar in both groups. We were unable to show a convincing functional benefit from surgery for patients with an acute rupture of the tendo Achillis compared with conservative treatment in plaster.

Abstract
PURPOSE Treatment of acute subcutaneous Achilles tendon rupture remains challenging. Whereas the results of conservative and operative treatment are inconsistent, early mobilisation treatment seems to be beneficial. Besides suture repair, operative treatment using adhesives reveals promising results. Our hypothesis was that a gluing technique provides initial stability comparable to sutures. METHODS In a biomechanical study, 18 fresh frozen sheep Achilles tendons were used to compare the biomechanical properties of suture repair using PDS® II and Bunnell's technique to tendon gluing using BioGlue® and Tissucol®. Load to failure testing was performed. RESULTS Ultimate failure loads of sutures (146.2 ± 30.8 N) are significantly superior to the techniques using BioGlue® (38.4 ± 18.3 N; p <0.0001) or Tissucol® (4.7 ± 2.5 N; p <0.0001). Interestingly, no significant differences in stiffness were found between the application of BioGlue® and PDS® II. CONCLUSIONS Suture repair provides significantly superior biomechanical properties compared to the use of both tested adhesives BioGlue® and Tissucol®. Based on the presented data we recommend the use of suture material for open Achilles tendon repair.

Abstract
Achilles tendon rupture is a common sports-related injury, with the incidence of acute ruptures continuing to increase. Achilles ruptures can be missed, or presentation may be delayed. Clinical tests assist diagnosis, with the Thompson and Matles tests being the most sensitive and specific. Ultrasound provides a valuable adjunct for diagnosing acute Achilles tendon ruptures. Traditionally, operative management has led to lower re-rupture rates than conservative treatment, but surgery increases the risk of complications such as adhesions and wound infection. More recently, however, non-operative treatment consisting of early mobilisation and rehabilitation, produces comparable re-rupture rates and functional outcomes to surgery. Percutaneous surgery may reduce the risk of operative complications, but needs to be more widely practised. In the present review we discuss the anatomy, aetiology, mechanism of injury, clinical assessment and investigations for diagnosing acute Achilles tendon ruptures. The debate regarding operative versus non-operative management is also considered.

Abstract
PURPOSE The purpose of this prospective randomized controlled study was to evaluate the long-term results after an acute Achilles tendon rupture in patients treated surgically or non-surgically. The focus was to evaluate whether any improvements occurred between the one and 2-year evaluation. METHOD Eighty-one patients (67 men, 14 women) with a mean (SD) age of 42 (9.1) were included in this study. Forty-two patients were treated surgically, and 39 treated non-surgically otherwise the treatment was identical for the two groups. All patients were evaluated using the Achilles tendon Total Rupture Score (ATRS), the Physical Activity Scale (PAS) and validated functional tests one and 2 years after injury. RESULTS There were significant functional deficits on the injured side compared with the contralateral side 2 years after Achilles tendon rupture, regardless of treatment. Only minor improvements, even though statistically significant, occurred between the 1- and 2-year evaluations. The physical activity level remained significantly reduced as compared with prior to injury, but the ATRS mean was relatively high in both groups (89 and 90). CONCLUSION This long-term follow-up indicates that the majority of patients with an Achilles tendon rupture have not fully recovered (in regards to symptoms, physical activity level and function) 2 years after injury regardless of surgical or non-surgical treatment. Furthermore, only minor improvements occur between the 1- and 2-year evaluations. This indicates that to enhance the final outcome the focus should be on improvements in treatment within the first year. The patients appear to have adjusted to their impairments since the patient-reported outcome is relatively high in spite of functional deficits and lower activity level compared with pre-injury. LEVEL OF EVIDENCE Prospective randomized study, Level I.

Abstract
BACKGROUND The primary aim of this study was to provide an estimate of effect size for the functional outcome of operative versus non-operative treatment for patients with an acute rupture of the Achilles tendon using accelerated rehabilitation for both groups of patients. The secondary aim was to assess the use of a comprehensive cohort research design (i.e. a parallel patient-preference group alongside a randomised group) in improving the accuracy of this estimate within an orthopaedic trauma setting. METHODS Pragmatic randomised controlled trial and comprehensive cohort study within a level 1 trauma centre. Twenty randomised participants (10 operative and 10 non-operative) and 29 preference participants (3 operative and 26 non-operative). The ge range was 22-72 years and 37 of the 52 patients were men. All participants had an acute rupture of their Achilles tendon and no other injuries. All of the patients in the operative group had a simple end-to-end repair of the tendon with no augmentation. Both groups then followed the same eight-week immediate weight-bearing rehabilitation programme using an off-the-shelf orthotic. The disability rating index (DRI; primary outcome), EQ-5D, Achilles Total Rupture Score and complications were assessed ed at two weeks, six weeks, three months, six months and nine months after initial injury. RESULTS At nine months, there was no significant difference in DRI between patients randomised to operative or non-operative management. There was no difference in DRI between the randomised group and the parallel patient preference group. The use of a comprehensive cohort of patients did not provide useful additional information as to the treatment effect size because the majority of patients chose non-operative management. CONCLUSIONS Recruitment to clinical trials that compare operative and non-operative interventions is notoriously difficult; especially within the trauma setting. Including a parallel patient preference group to create a comprehensive cohort of patients has been suggested as a way of increasing the power of such trials. In our study, the comprehensive cohort model doubled the number of patients involved in the study. However, a strong preference for non-operative treatment meant that the increased number of patients did not significantly increase the ability of the trial to detect a difference between the two interventions.
