Supervised Physiotherapy Improves Three-Dimensional (3D) Gait Parameters in Patients after Surgical Suturing of the Achilles Tendon Using an Open Method (SSATOM). J Clin Med 2022; 11:jcm11123335. [PMID: 35743407 PMCID: PMC9225029 DOI: 10.3390/jcm11123335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 06/01/2022] [Accepted: 06/06/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND The aim of this study was to assess the effectiveness of 38 supervised postoperative physiotherapy (SVPh) visits conducted between 1 and 20 weeks after SSATOM on the values of 3D gait parameters measured at 10 and 20 weeks after surgery. MATERIAL Group I comprised male patients (n = 22) after SSATOM (SVPh x = 38 visits) and Group II comprised male patients (n = 22) from the control group. METHODS A non-randomized, open-label, controlled clinical trial was performed in the two groups to obtain the following values: Step length (cm), stride length (cm), step width (cm), next stance phase (%), swing phase (%), double support (%), gait velocity (m/s), and walking frequency (step/min). The measurements were carried out using the BTS SMART system (Italy). RESULTS Orthopedic examination showed no pain, a negative result of Thompson and Matles tests, and proper healing of Achilles tendon (ultrasound image). In Group I, between 10 and 20 weeks after SSATOM, there was a statistically significant improvement in all tested gait parameter values (p ≤ 0.001 to 0.009). CONCLUSIONS Conducting 38 SVPh visits significantly improved the values of the analyzed kinematic and spatiotemporal gait parameters in patients in the twentieth week after SSATOM, which were mostly close to the non-operated side and the results of the control group. However, the gait speed and stride length were not close to the results of the control group.

Do the heel-rise test and isometric strength improve after Achilles tendon repair using Dresden technique? Foot Ankle Surg 2022; 28:37-43. [PMID: 33509663 DOI: 10.1016/j.fas.2021.01.007] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 01/11/2021] [Accepted: 01/16/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND Achilles' tendon ruptures result in impaired plantar flexion strength and endurance. It is interesting to know the plantar flexion strength, the number of heel-rise repetitions, and the maximal calf circumference following Achilles' tendon ruptures repair. METHODS Both the injured and non-injured legs of thirty male patients with Achilles' tendon ruptures treated with the percutaneous Dresden technique were compared with the ankle function of 30 healthy participants. Rehabilitation involved partial weight-bearing for three weeks and then increased to full weight-bearing and ankle exercises. RESULTS The injured legs had weaker plantar flexion strength (1.64 ± 0.17 Nm/kg) compared with the non-injured legs (1.91 ± 0.24 Nm/kg; p = 0.002) and the healthy participants' legs (1.93 ± 0.32 Nm/kg; p < 0.001). The non-injured leg had greater ability in doing heel-rise repetitions (39.4 ± 6.1 rep.) compared with the injured legs (37.2 ± 5.7 rep.; p < 0.023) and the healthy participants' legs (31.0 ± 13.0 rep.; p < 0.001). CONCLUSIONS The injured leg had not recovered full isometric strength but had improved heel-rise repetition.

[PMID: 32266518 DOI: 10.1007/s00402-020-03437-z] [Citation(s) in RCA: 36] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Indexed: 11/25/2022]
Abstract
INTRODUCTION Despite the presence of various different surgical procedures, the preferable technique for repair of acute Achilles tendon ruptures is unknown and, therefore, object of discussions. The purpose of this meta-analysis was to compare clinical outcomes and complication-rates between the minimally invasive and the standard open repair of acute Achilles tendon ruptures. MATERIALS AND METHODS This meta-analysis was performed according to the PRISMA guidelines. In September 2019 the main databases were accessed. All clinical trials of evidence level I to III comparing minimally invasive vs. open surgery of Achilles tendon rupture were included in the present study. Only articles reporting quantitative data under the outcomes of interest were included. Missing data under the outcomes of interest warranted the exclusion from the present work. For the statistical analysis we referred to the Review Manager Software Version 5.3. (The Nordic Cochrane Centre, Copenhagen). Continuous data were analysed through the inverse variance method. For the effect estimate the mean difference was used. Dichotomous data were analysed through the Mante-Haenszel method via odd ratio effect measure. The confidence interval was set at 95% in all the comparisons. Values of P < 0.05 were considered statistically significant. RESULTS A total of 25 articles were included for meta-analysis. The funnel plot revealed poor data dispersion, attesting to this study a low risk of publication bias. The quality of the methodological assessment was moderate. Data from 2223 (1055 open, 1168 minimally invasive) surgical procedures were extracted. The mean follow-up was of 24.29 ± 22.4 months. The open group reported a lower value of post-operative palpable knot at last follow-up and a lower rate of sural nerve palsy. In the minimally-invasive group a shorter surgery duration and a lower rate of post-operative wound necrosis and reduced risk of wound scarring and adhesions has been evidenced. The minimally-invasive cohort detected the lowest values of superficial and deep infections. In both groups no significant difference was shown in re-rupture rate. CONCLUSIONS Compared to the minimally-invasive Achilles tendon reconstruction, the open procedure evidenced a lower rate of sural nerve palsy and postoperative palpable knot, whereas in the minimally-invasive reconstruction group quicker surgery duration, a lower rate of post-operative wound necrosis, superficial and deep infections and less scar tissue adhesions could be observed. No relevant discrepancies were detected among the two techniques in terms of post-operative re-rupture.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17134642. [PMID: 32605170 PMCID: PMC7369810 DOI: 10.3390/ijerph17134642] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 06/23/2020] [Accepted: 06/24/2020] [Indexed: 11/16/2022]
Abstract
The purpose of this study was to compare the inter-limb joint kinematics, joint moments, muscle forces, and joint reaction forces in patients after an Achilles tendon rupture (ATR) via subject-specific musculoskeletal modeling. Six patients recovering from a surgically repaired unilateral ATR were included in this study. The bilateral Achilles tendon (AT) lengths were evaluated using ultrasound imaging. The three-dimensional marker trajectories, ground reaction forces, and surface electromyography (sEMG) were collected on both sides during self-selected speed during walking, jogging and running. Subject-specific musculoskeletal models were developed to compute joint kinematics, joint moments, muscle forces and joint reaction forces. AT lengths were significantly longer in the involved side. The side-to-side triceps surae muscle strength deficits were combined with decreased plantarflexion angles and moments in the injured leg during walking, jogging and running. However, the increased knee extensor femur muscle forces were associated with greater knee extension degrees and moments in the involved limb during all tasks. Greater knee joint moments and joint reaction forces versus decreased ankle joint moments and joint reaction forces in the involved side indicate elevated knee joint loads compared with reduced ankle joint loads that are present during normal activities after an ATR. In the frontal plane, increased subtalar eversion angles and eversion moments in the involved side were demonstrated only during jogging and running, which were regarded as an indicator for greater medial knee joint loading. It seems after an ATR, the elongated AT accompanied by decreased plantarflexion degrees and calf muscle strength deficits indicates ankle joint function impairment in the injured leg. In addition, increased knee extensor muscle strength and knee joint loads may be a possible compensatory mechanism for decreased ankle function. These data suggest patients after an ATR may suffer from increased knee overuse injury risk.

Abstract
The goal of treatment after Achilles tendon rupture (ATR) is to restore appropriate tension to the tendon, so that normal baseline strength and functional soft-tissue length can be achieved. The assessment of plantarflexion strength has shown widespread variability. The purpose of this study is to document variations in strength assessment after the treatment of ATR in the literature. A comprehensive literature review was performed. In total, 2758 articles were found on Achilles tendon rupture and Achilles tendon strength measurement. The full text of articles including strength as a functional outcome measurement in the abstract were assessed. All objective strength measurements performed were reviewed and recorded for comparison. One-hundred articles were included in our study. In 78 articles, a dynamometer was used to measure strength, whereas in 22 articles, an endurance test (n=14) or formal gait assessment (n=8) was applied. When a dynamometer was used, there was wide variability in the various methods used including the incorporation of both isokinetic (n = 65) and isometric (n = 29) exercises utilizing varying degrees of knee flexion and patient testing position. Furthermore, the number of measurements at certain angular velocities varied. This study illustrates that no general consensus exists regarding an optimal method for measuring strength after ATR. The variability creates difficulty and challenges medical professionals' ability to formulate consistent conclusions when determining functional performance outcomes. A more uniform way of measuring strength after ATR may allow for better comparisons between studies in the literature, potentially leading to a better understanding of strength. Levels of Evidence: Therapeutic, Level II.

Abstract
BACKGROUND For the treatment of acute Achilles tendon rupture, early rehabilitation after surgical repair is believed to be a useful method. The purpose of this study was to evaluate the outcome of open tenorrhaphy followed by early rehabilitation. METHODS A total of 112 patients who underwent open repair and early rehabilitation for acute Achilles tendon rupture from January 2003 to March 2015 were retrospectively reviewed. These 112 patients (80 men, 32 women) had an average age of 43.1 years (22-62 years), and the mean follow-up period was 91.8 months (12-171 months). A short leg cast was applied postoperatively for an average of 16.5 days (12-20 days). The mean duration of bracing was 6.9 weeks (6-8 weeks). Each patient was assessed based on range of motion, single heel raising test, calf circumference compared to the contralateral limb, ability to return to previous activity, the Arner-Lindholm scale, and the American orthopaedic foot and ankle society (AOFAS) hind foot scale. Isokinetic plantar flexion power was also checked. RESULTS All patients were fully satisfied (AOFAS ≥ 90) with the treatment results, and 96 patients were able to return to their previous athletic activities. As assessed by the Arner-Lindholm scale, 103 cases were rated as excellent and the other 9 cases were rated as good. At the 1-year follow-up period, single heel raise and hopping was possible in every patient. Compared to the contralateral side, 10 subjects (8.9%) had minor limitation of dorsiflexion motion, and an average of 1.6 cm calf circumference difference without functional disabilities. There were no major complications such as re-rupture, nerve injury, or infection. CONCLUSION For acute Achilles tendon ruptures, open surgical repair with optimal length restoration, followed by earlier rehabilitation results in good functional outcomes and a successful return to pre-injury levels of physical activity without major complications. LEVEL OF EVIDENCE Level IV.

Abstract
BACKGROUND Rupture of the Achilles tendon (AT) is frequent in young recreational athletes. Conservative management, open surgery and percutaneous/minimally invasive approaches are all advocated, and conflicting data are available. This study compared functional and anthropometric outcomes of patients who underwent open or percutaneous repair. METHODS A retrospective comparative study, in which 38 patients underwent open and percutaneous techniques to manage AT ruptures. For functional assessment, the calf circumference of both injured and uninjured legs was evaluated. Isokinetic testing included total plantar flexion work, peak plantar flexion torque, total dorsiflexion work peak and dorsiflexion torque. The Achilles Tendon Rupture Score (ATRS) and the American Orthopedic Foot and Ankle Score (AOFAS) were evaluated at a final minimum follow-up of 12months. RESULTS No major complications were observed. The average time to return to sport was 9months. AOFAS and ATRS values did not differ statistically between groups. Isokinetic variables and circumference were similar in the operated and non-operated limb in both groups, and did not differ either when comparing open and percutaneous repair. CONCLUSIONS Open and percutaneous repair of a torn Achilles tendon produced similar functional outcomes.

Abstract
BACKGROUND Open Achilles tendon repairs (OATR) are associated with high complication rates. Minimally invasive surgery (MIS) techniques like the Achillon Achilles tendon repair (AATR) were developed to reduce this. We performed a systematic review and meta-analysis to compare OATR with AATR. METHODS We performed an extensive literature search including all studies that compared the two techniques. Outcomes assessed included overall complication rate, re-rupture rate, sural nerve injury, wound length, The American Orthopaedic Foot and Ankle Scores (AOFAS) scores and return to sports. RESULTS Eight studies were suitable for inclusion totalling 210 patients in the AATR group vs 233 patients in the OATR group. Total complication rates were significantly reduced in the Achillon patients with odd ratio of 0.14 (CI 95%, 0.08-0.27, P<0.00001) in favour. There were no significant differences in re-rupture rate, sural nerve injury, return to sports and AOFAS scores following repair between the two groups. CONCLUSIONS AATR has fewer overall complications compared with OATR. It should be considered as an alternative to open surgical repair.

Abstract
BACKGROUND To assess the outcome of delayed repair of ruptured Achilles tendon using the Achillon mini-open technique. METHODS A review of all patients who underwent delayed repair (>10 days post injury) of ruptured Achilles tendon with mini invasive technique was compared to acute repairs carried out at the same unit. Leppilahti Score and Achilles Tendon Total Rupture Score (ATRS) were utilised. Complication rates including re-rupture were also reviewed. RESULTS 14 patients were identified as having delayed repair (11-31 days). The mean follow-up period was 71 months (range: 58-92). There were no statistically significant difference in the Leppilahti Score and ATRS compared to patients treated acutely (<10 days post injury) in the same time period. 79% of patients with delayed repair reported good to excellent, comparable to 80% of patients having undergone acute repair. CONCLUSIONS For those patients who would benefit from surgical repair, a mini-open technique using the Achillon suture-passing device remains a safe and reliable option for delayed presentation of 11-31 days.

Abstract
BACKGROUND Despite the increasing incidence of Achilles tendon (AT) ruptures, there is a lack of information on the possible risks associated with regular running and walking for exercise after an injury. There are some known kinematic gait changes after an AT rupture, especially at the knee. However, it is not clear whether runners with AT ruptures may be at risk for secondary knee injuries during shod or barefoot running/walking. PURPOSE/HYPOTHESIS The purpose of this study was to compare the kinematics and kinetics of barefoot walking and barefoot and shod running between athletes with a history of AT ruptures and a healthy control group. We hypothesized that there would be increased knee joint loads in the affected limb of the AT rupture group, especially during shod running. STUDY DESIGN Controlled laboratory study. METHODS Ten patients who had undergone surgical treatment of a unilateral acute AT rupture (6.1 ± 3.7 years postoperatively ) and 10 control participants were matched according to age, sex, physical activity, weight, height, and footfall type. The kinematics and kinetics of barefoot walking and barefoot and shod running were recorded using a high-speed motion capture system synchronized with force platforms. RESULTS The main outcome measures were lower extremity joint angles and moments during the stance phase of walking and running. After AT repair, athletes had increased internal knee abduction moments during shod and barefoot running compared with the healthy control group (P < .05, η2 > 0.14). There were no significant differences in kinematics and kinetics during walking between the AT rupture and healthy control groups (P ≥ .05). CONCLUSION After an AT rupture, athletes had increased internal knee abduction moments during running compared with the healthy control group. CLINICAL RELEVANCE The increased abduction loads on the knee in patients with an AT rupture could lead to further running-related injuries. However, barefoot walking may be used as a proprioceptive exercise without an increased risk of overuse injuries in these patients.

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

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

Abstract
The relationship between surgical technique and ankle biomechanical properties after surgery for acute rupture of the Achilles tendon (ATR) has not yet been fully investigated. Platelet-rich fibrin (PRF) matrices seem to play a central role in the complex processes of tendon healing. Our aim was to analyze the biomechanical characteristics, stiffness, and mechanical work of the ankle during walking in patients who had undergone surgery after ATR with and without PRF augmentation. We performed a retrospective review of all consecutive patients who had been treated with surgical repair after ATR. Of the 20 male subjects enrolled, 9 (45%) had undergone conventional open repair of the Achilles tendon using the Krackow technique (no-PRF) and 11 (55%) had undergone surgery with PRF augmentation. An additional 8 healthy subjects were included as a control group. A gait analysis evaluation was performed at 6 months after surgery. The percentage of the stance time of the operated leg, double-support time of the healthy leg, and net work of the ankle during the gait cycle showed statistically significant differences between the no-PRF and the healthy group (p < .005). No differences were found between the PRF and healthy groups. Treatment with suture and PRF augmentation could result in significant functional improvements in term of efficiency of motion.

Abstract
BACKGROUND Surgical management of Achilles tendon rupture is still controversial: open techniques have a higher rate of soft tissue complications but a lower incidence of re-rupture than percutaneous tenorrhaphies. The aim of our retrospective study was to analyze and compare clinical and functional results in patients treated with either the conventional open or minimally invasive suture treatment with the Achillon® system. METHODS A retrospective review of 140 patients was performed; 72 were treated with open tenorrhaphy, 68 with the minimally invasive Achillon® suture system. RESULTS With a comparable re-rupture rate, there was a statistically significant reduction in surgical time, incidence of minor complications, time required to return to sport activities and return to work in the minimally invasive group. CONCLUSIONS Achillon® mini-invasive suture system is a reliable tool for the Achilles tendon ruptures, able to reduce the incidence of soft tissues complications if compared to the classic open tenorrhaphy, while maintaining strength of the suture and leading to superimposed functional outcomes.

Abstract
BACKGROUND The intent of this study was to determine whether differences in function, walking characteristics, and plantar pressures exist in individuals after operative fixation of an intra-articular calcaneal fracture (HFX) compared with individuals with operative repair of an Achilles tendon rupture (ATR). METHODS Twenty patients (ten with HFXs and ten with ATRs) were recruited approximately 3.5 months after operative intervention. All of the participants completed the Lower Extremity Functional Scale and had their foot posture assessed using the Foot Posture Index. Walking velocity was assessed using a pressure mat system, and plantar pressures were measured using an in-shoe sensor. In addition to between-group comparisons, the involved foot was compared with the uninvolved foot for each participant. RESULTS There were no differences in age, height, weight, or number of days since surgery between the two groups. The HFX group had lower Lower Extremity Functional Scale scores, slower walking velocities, and different forefoot loading patterns compared with the ATR group. The involved limb of both groups was less pronated. CONCLUSIONS The results indicate that individuals with an HFX spend more time on their involved limb and walk slower than those with an ATR. Plantar pressures in the HFX group were higher in the lateral forefoot and lower in the medial forefoot and in the ATR group were symmetrically lower in the forefoot.

Abstract
PURPOSE The ideal treatment for Achilles tendon ruptures is still unknown. Biomechanical were correlated to radiological and clinical parameters to study outcomes. METHODS In this retrospective, assessor-blinded multi-centre cohort study, 52 patients with unilateral Achilles tendon rupture were assessed, each at least 3 years after injury. Patients underwent open surgery, percutaneous surgery or non-surgical treatment of Achilles tendon rupture. Both legs underwent plantar pressure distribution and isokinetic measures. Demographic parameters, maximum calf circumference (MCC) and clinical scores (American Orthopaedic Foot and Ankle Society, Achilles tendon rupture score, Hannover) were also evaluated. Complications were not assessed. RESULTS Peak plantar flexion torque (PPFT) was significantly weaker on the treated side compared to the untreated leg [80.4 ± 29.7 Nm (mean ± SD) vs. 92.1 ± 27.4 Nm, p < 0.0001]. PPFT and push-off force (POFF) were not different between treatment groups nor was there a leg difference in POFF alone. There was only a weak correlation of clinical scores and PPFT or POFF, respectively. MCC correlated significantly with both PPFT (R (2) = 0.21, p = 0.01) and POFF (R (2) = 0.29, p < 0.0001). POFF appeared to be a predictor of PPFT (R (2) = 0.31, p < 0.0001). Open surgery outperformed non-surgical treatment in terms of centre-of-pressure line (p = 0.007), torque per muscle volume (p = 0.04) and relative POFF per body weight (p = 0.02) and relative in side comparison (p = 0.03). CONCLUSIONS Clinical scores do not predict biomechanical outcomes. Clinically measured MCC is a good predictor of PPFT and POFF and can easily be used in clinical practice. Relative POFF in side comparison as well as per body weight favours surgical treatment.

Abstract
Achilles tendon rupture is a disabling injury that requires a long recovery time. We describe a unique case of a 46-year-old male who had undergone gait analysis as part of a personal physical examination and who, 16 months later, ruptured his left Achilles tendon while running. With gait kinematic and kinetic data available both before and after his injury, we determined the residual gait asymmetries on his uninjured side and compared the pre- and postinjury measurements. We analyzed his gait at 1, 4, and 7 weeks after his return to full weightbearing. Compared with the preinjury values, at 7 weeks he had almost complete range of motion in his left ankle (-2%) and a slight increase in gait velocity (+6%) and cadence (+3%). The peak power of his injured ankle was 90% of its preinjury value. In contrast, the unaffected ankle was at 118%. These observations suggest that measuring the asymmetries of the gait cycle, especially at the beginning of rehabilitation, can be used to improve treatment. We had the patient strengthen his ankle using a stationary bicycle before he returned to running. Kinetics also appears to be more powerful than kinematics in detecting functional asymmetries associated with reduced calf strength, even 15 weeks after surgery. Gait analysis could be used to predict the effectiveness of rehabilitation protocols and help calibrate and monitor the return to sports participation while preventing overloading muscle and tendon syndromes.

Abstract
INTRODUCTION This review provides a comprehensive description of clinical, functional outcomes, and complications after open and minimally invasive surgery for Achilles tendon ruptures. SOURCES OF DATA We systematically searched Medline (PubMED), EMBASE, CINHAL, Cochrane, Sports Discus and Google scholar databases using the combined keywords 'open repair', 'percutaneous surgery', 'minimally invasive surgery' 'Achilles tendon rupture', 'complications', 'infections', 'wound disorders' to identify articles published in English, Spanish, French and Italian. AREAS OF AGREEMENT Twelve studies fulfilled our inclusion criteria. Six studies were retrospective, five were randomized controlled trials and one was a prospective investigation. Of a total of 781 patients, 375 underwent open repair and 406 percutaneous surgery. Different procedures were performed for open and minimally invasive repair. AREAS OF CONTROVERSY The range of motion was significantly greater after percutaneous repair than open surgery. The number of complications that occurred after open surgery was higher than after minimally invasive surgery. GROWING POINTS Minimally invasive surgery is less expensive and less time demanding. AREAS TIMELY FOR DEVELOPING RESEARCH Minimally invasive and open surgery of the Achilles tendon are grossly equivalent. However, iatrogenic neurological complications are more frequent after percutaneous repair. Novel percutaneous repairs have been proposed to minimize the risk of sural nerve injury.

Abstract
BACKGROUND Minimally invasive Q3 repair has been proposed for acute Achilles tendon rupture with low rate of complications. However there are still controversies about optimal technique. In this study we aimed to describe Endobutton-assisted modified Bunnell configuration as a new Achilles tendon repair technique and evaluate its biomechanical properties comparing with native tendon and Krackow technique. METHODS 27 ovine Achilles tendons were obtained and randomly placed into 3 groups with 9 specimens ineach. The Achilles tendons were repaired with Endobutton-assisted modified Bunnell technique in group 1, Krackow suture technique in group 2 and group 3 was defined as the control group including native tendons. Unidirectional tensile loading to failure was performed at 25mm/min. Biomechanicalproperties such as peak force to failure (N), stress at peak (MPa), elongation at failure, and Young'smodulus (GPa) was measured for each group. All groups were compared with each other using one-wayANOVA followed by the Tukey HSD multiple comparison test (a=0.05). RESULTS The average peak force (N) to failure of group 1 and group 2 and control group was 415.6±57.6, 268.1±65.2 and 704.5±85.8, respectively. There was no statistically significant difference between native tendon and group 1 for the amount elongation at failure (p>0.05). CONCLUSIONS Regarding the results, we concluded that Endobutton-assisted modified Bunnell technique provides stronger fixation than conventional techniques. It may allow early range of motion and can be easily applied in minimally invasive and percutaneous methods particularly for cases with poor quality tendon at the distal part of 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.
