In this report we aimed to present clinical features of a case of bilateral spontaneous achilles tendon rupture and tried to investigate potential etiologic factors. A 54 year old man was admitted to our emergency department as complaining bilateral ankle pain at the retrocalcaneal region. He had no trauma, any comorbidities or any drug consumption history. Painful achilles tendon gaps proximal to his ankles had been palpated and bilateral Thompson’s test positivity had been noted (Figures 1 and 2). He was unable to rise upon his toes however he was able to walk. American Orthopedic Foot and Ankle Society Hindfoot Scoring was calculated as 78 points. The rupture had been verified with a magnetic resonance imaging and his laboratory findings were all within normal limits (Figures 3 and 4).The patient did not approve an operation so conservative treatment with dorsiflexion limiting brace was applied and strengthening and stretching exercises of gastrosoleus was suggested. Atraumatic and bilateral cases with achilles rupture should be well investigated whether any systemic factors are coexistent. Besides well known corticosteroids or fluoroquinolone exposure, endocrinologic and rheumatological diseases, hypercholesterolaemia should be evaluated in terms of predisposing causes. Patients who have to use corticosteroids or fluoroquinolone, should be informed about achilles tendon rupture and be suggested do regular physical exercises in order to reduce the rupture risk. Despite predisposing factors, sometimes nothing can be associated with achilles tendon rupture as in our case. Genetic predisposition or a degenerative process of a tendon due to age may be underlying cause like in rotator cuff tears.展开更多

New Zealand rabbits, aged 14 weeks, underwent tenotomy followed immediately byAchilles tendon microsurgery to repair the Achilles tendon rupture. The tendon was then immobilized or subjected to postoperative early motion treatment (kinesitherapy). Mass spectrography results showed that after 14 days of motion treatment, 18 protein spots were differentially expressed, among which, 12 were up-regulated, consisting of gelsolin isoform b and neurite growth-related protein collapsing response mediator protein 2. Western blot analysis showed that gelsolin isoform b was up-regulated at days 7-21 of motion treatment. These findings suggest that active Achilles tendon kinesitherapy promotes the neurite regeneration of a ruptured Achilles tendon and gelsolin isoform b can be used as a biomarker for Achilles tendon healing after kinesitherapy.展开更多

Methods: We conducted a case-control study. Between 2009 and 2014, we performed surgical revisions of closed acute Achilles tendon ruptures in our hospital in 146 patients, of which 71 patients (2012-2014) received percutaneous suturing using Dresden instruments, and 75 patients (2009-2012) underwent open suturing. After a minimum period of 1 year post surgery, we performed clinical follow-up in 25 patients of each of the groups using the AOFAS hind foot score and the SF-12 questionnaire. Furthermore, we implemented a clinical questionnaire with a reference population of 200 healthy individuals. Results: Mean age in the total population of 146 patients was 47 years (range 21 to 83 years) at the time of surgery. The duration of the surgical procedure with percutaneous suturing was significantly shorter (24 versus 43 minutes, p < 0.0001), the complication rate was significantly lower (2.81% versus 10.7%, p < 0.0001), and the time of hospitalisation was significantly shorter (3 versus 4 days, p < 0.0001) when compared to open suturing. During follow-up, no significant differences between the two groups were observed in terms of descriptive parameters. Furthermore, ultrasound examinations of both follow-up populations did not show any significant difference. From a clinical perspective, the good to very good results achieved with open suturing (as measured with the AOFAS hind foot score and the SF-12 questionnaire) have not been significantly improved with percutaneous suturing. The additional use of a new clinical score (with the reference population) demonstrated good to very good consistency with the established scores. Conclusion: In our population, percutaneous Achilles tendon suturing showed significantly lower complication rates and significantly shorter procedure times when compared to open suturing. However, percutaneous suturing did not show clinical improvements of the good to very good results that were achieved with open suturing (as measured with the AOFAS back foot score and the SF-12 questionnaire). The implementation of a new and simple score for the clinical evaluation of Achilles tendon injuries resulted in good to very good consistency with the established questionnaires and, thus, offered a straightforward and rapid alternative when compared to the more elaborate scores.展开更多

The occurrence of compartment syndrome is not recognized as a potential complication after Achilles tendon rupture, and only a small number of such cases have been reported. We report the case of a 16-year-old girl with rupture of the right Achilles tendon. On postoperative day 4, she experienced severe anterior ankle pain. A blood test revealed a creatine kinase level of 7976 IU/L;the pressure in the distal anterior compartment was 90 mmHg and proximal compartment was 40 mmHg (needle manometer method). Magnetic resonance imaging (MRI) revealed a signal change in the anterior compartment. Anterior compartment syndrome was diagnosed on the basis of clinical findings, pressure measurements, and MRI findings. Emergency surgery was performed, and the anterior fascia was released. However, the dysfunction in the form of limited range of ankle motion remained. The cause of the compartment syndrome after Achilles tendon rupture was unclear. The patient’s involvement in basketball and positioning of the ankle in plantar flexion with a cast might have been contributing factors in our case. We need to consider the possibility that compartment syndrome may occur after Achilles tendon rupture.展开更多

The aim of this experimental study was to evaluate the effect of a non-steroidal anti-inflammatory drug (NSAID) and of aerobic exercise, in an isolated fashion and combined, on cell proliferation and on the biomechanical aspects of the Achilles tendon during healing process after a complete tenotomy in 156 male Wistar rats. Half of the animals received an intra-muscular injection of tenoxicam for 7 days and exercise was initiated on the 8th day for half the animals of each group. Animals were sacrificed at 1, 2, 4 and 8 weeks after the tenotomy and cell proliferation was evaluated by immunohistochemistry for PCNA, biomechanical evaluation was performed with ultimate load and gait cycle analysis was also carried out. Animals were divided into four treatment groups: A) no NSAID and no exercise (control group);B) NSAID plus exercise;C) no NSAID, with exercise;D) NSAID and no exercise. We used the test of two-way analysis of variance with equal cells number, Kruskal-Wallis test and also, Bonferroni method, in the R Project program 3.5.0. The highest intensity of PCNA immunostaining was found at 2 weeks in all groups except for group A (control) that had the highest intensity at 1 week. Animals submitted to exercise had significantly higher (P = 0.02) ultimate loads when compared to animals that were not submitted to exercise at 8 weeks after injury. The animals that received NSAID presented with a more stable gait cycle than the animals that did not receive NSAID. Aerobic exercise, initiated early after a complete Achilles tendon tenotomy, was beneficial to the biomechanical aspects of the tendon that occur during tendon regeneration and the combined use of NSAID improved the gait’s characteristics which could be protective against re-ruptures.展开更多

Surgical procedures...Rupture of the Achilles tendon is one of the most frequent tendon injuries in humans. However, there is no standard surgical technique thus far to reproduce complete rupture of this tendon in rats. Surgical procedures were performed in Wistar rats under light microscopy, with posterior longitudinal incision and preservation of the plantaris tendon. The animals were sacrificed on 2nd and 8th postoperative week and we used hematoxilin and eosin, picrosirius-red and Weigert’s resorcin-fuchsin to observe general tendon healing. The mean operative time was one minute and 24 seconds. Histological studies showed cellular proliferation and fibrillogenesis at two weeks, with decreased amounts of cellularity and elastic fibers at the 8th week, besides changes in structural organization of collagen fibers. The complete Achilles tenotomy in rats, was improved under light microscopy and sparing the plantaris tendon. This surgical technique was simple and quick, showed signs of normal healing process, could be easily reproducible, and triggered translational researches in this area.展开更多

Therefore, prevention of peritendinous adhesion after surgical repair of tendon is a major challenge. The aim of this study was to explore the possible application of a collagen membrane for the prevention or attenuation of peritendinous adhesions. Methods Sprague-Dawley (SD) rat Achilles tendon was cut and sutured by a modified Kessler's technique with or without the collagen membrane wrapped. Macroscopic, morphological and biomechanical evaluations were applied to examine the recovery of the injured tendon at 4 and 8 weeks after surgery. Results The surgery group wrapped by collagen membranes had a better outcome than the group with surgery repair only. In the collagen membrane-treated group, less adhesion appeared, stronger tensile strength was detected, and more tendon fibers and collagen I expression were observed morphologically. Conclusion Wrapping the tendon with a collagen membrane may be an efficient approach for tendon repair and preventing tendon adhesion after its ruptures.展开更多

Methods: We conducted a case-control study. Between 2009 and 2014, we performed surgical revisions of closed acute Achilles tendon ruptures in our hospital in 146 patients, of which 71 patients (2012-2014) received percutaneous suturing using Dresden instruments, and 75 patients (2009-2012) underwent open suturing. After a minimum period of 1 year post surgery, we performed clinical follow-up in 25 patients of each of the groups using the AOFAS hind foot score and the SF-12 questionnaire. Furthermore, we implemented a clinical questionnaire with a reference population of 200 healthy individuals. Results: Mean age in the total population of 146 patients was 47 years (range 21 to 83 years) at the time of surgery. The duration of the surgical procedure with percutaneous suturing was significantly shorter (24 versus 43 minutes, p < 0.0001), the complication rate was significantly lower (2.81% versus 10.7%, p < 0.0001), and the time of hospitalisation was significantly shorter (3 versus 4 days, p < 0.0001) when compared to open suturing. During follow-up, no significant differences between the two groups were observed in terms of descriptive parameters. Furthermore, ultrasound examinations of both follow-up populations did not show any significant difference. From a clinical perspective, the good to very good results achieved with open suturing (as measured with the AOFAS hind foot score and the SF-12 questionnaire) have not been significantly improved with percutaneous suturing. The additional use of a new clinical score (with the reference population) demonstrated good to very good consistency with the established scores. Conclusion: In our population, percutaneous Achilles tendon suturing showed significantly lower complication rates and significantly shorter procedure times when compared to open suturing. However, percutaneous suturing did not show clinical improvements of the good to very good results that were achieved with open suturing (as measured with the AOFAS back foot score and the SF-12 questionnaire). The implementation of a new and simple score for the clinical evaluation of Achilles tendon injuries resulted in good to very good consistency with the established questionnaires and, thus, offered a straightforward and rapid alternative when compared to the more elaborate scores.
文摘Compartment syndrome may cause irreversible dysfunction if not treated correctly. The occurrence of compartment syndrome is not recognized as a potential complication after Achilles tendon rupture, and only a small number of such cases have been reported. We report the case of a 16-year-old girl with rupture of the right Achilles tendon. On postoperative day 4, she experienced severe anterior ankle pain. A blood test revealed a creatine kinase level of 7976 IU/L;the pressure in the distal anterior compartment was 90 mmHg and proximal compartment was 40 mmHg (needle manometer method). Magnetic resonance imaging (MRI) revealed a signal change in the anterior compartment. Anterior compartment syndrome was diagnosed on the basis of clinical findings, pressure measurements, and MRI findings. Emergency surgery was performed, and the anterior fascia was released. However, the dysfunction in the form of limited range of ankle motion remained. The cause of the compartment syndrome after Achilles tendon rupture was unclear. The patient’s involvement in basketball and positioning of the ankle in plantar flexion with a cast might have been contributing factors in our case. We need to consider the possibility that compartment syndrome may occur after Achilles tendon rupture.

文摘Achilles tendon rupture is one of the most frequent tendon injuries. The aim of this experimental study was to evaluate the effect of a non-steroidal anti-inflammatory drug (NSAID) and of aerobic exercise, in an isolated fashion and combined, on cell proliferation and on the biomechanical aspects of the Achilles tendon during healing process after a complete tenotomy in 156 male Wistar rats. Half of the animals received an intra-muscular injection of tenoxicam for 7 days and exercise was initiated on the 8th day for half the animals of each group. Animals were sacrificed at 1, 2, 4 and 8 weeks after the tenotomy and cell proliferation was evaluated by immunohistochemistry for PCNA, biomechanical evaluation was performed with ultimate load and gait cycle analysis was also carried out. Animals were divided into four treatment groups: A) no NSAID and no exercise (control group);B) NSAID plus exercise;C) no NSAID, with exercise;D) NSAID and no exercise. We used the test of two-way analysis of variance with equal cells number, Kruskal-Wallis test and also, Bonferroni method, in the R Project program 3.5.0. The highest intensity of PCNA immunostaining was found at 2 weeks in all groups except for group A (control) that had the highest intensity at 1 week. Animals submitted to exercise had significantly higher (P = 0.02) ultimate loads when compared to animals that were not submitted to exercise at 8 weeks after injury. The animals that received NSAID presented with a more stable gait cycle than the animals that did not receive NSAID. Aerobic exercise, initiated early after a complete Achilles tendon tenotomy, was beneficial to the biomechanical aspects of the tendon that occur during tendon regeneration and the combined use of NSAID improved the gait’s characteristics which could be protective against re-ruptures.

文摘Purpose:Previous studies have confirmed that Achilles tendon occurs Achilles thickening after repair surgery of the rupture.Although this mechanism has been elucidated in the laboratory,there are few reports on its impact on clinical function.We designed a retrospective study to investigate the Achilles thickening after Achilles tendon rupture repair and its correlation between the elasticity and postoperative function.Methods:In this retrospective analysis,patients who underwent surgical treatment for acute Achilles tendon rupture from April 2016 to April 2020 were included.All the patients were regularly followed up at 3 months,1 year,and 2 years after surgery.American Orthopaedic Foot Ankle Surgeon(AOFAS)scale and Leppilahti score were used to evaluate functional outcomes.Achilles elasticity was measured by ultrasound shear wave of elasticity.Achilles thickening was calculated as maximal transverse and longitudinal diameter in cross-sectional plane of magnetic resonance scan.Sample t-tests was used for different follow-up periods.Correlation between Achilles thickening and other factors were analyzed using Pearson's method.p<0.05 indicates a statistically significant difference.Results:AOFAS scale and Leppilahti score at 1 year were significantly higher than at 3 months postoperatively(both p<0.001).These functional scales were also improved at 2-year follow-up significantly(both p<0.001).The dorsiflexion difference showed gradually recovery in each follow-up period(t=-17.907,p<0.001).The elasticity of the Achilles appeared to continuously decreases during the postoperative follow-up period in all position sets(p<0.001).In thickening evaluation,the cross-sectional area of the thickest plane of Achilles was significantly higher at 1 year postoperatively(310.5±25.2)mm^(2)than that at 3 months postoperatively((278.0±26.2)mm^(2),t=-8.219,p<0.001)and became thinner in 2-year magnetic resonance scan((256.1±15.1)mm^(2),t=16.769,p<0.001).The correlations between Achilles thickening,elasticity,and functional outcome did not show statistical significance(p>0.05)in every follow-up period.Conclusion:Achilles tendon thickens after surgery in the 1st year,but begins to gradually return to thinning about 2 years after surgery.There was no significant correlation between the increase and decrease of thickening and the patients'clinical function scores,Achilles elasticity,and bilateral ankle dorsiflexion difference.

文摘Rupture of the Achilles tendon is one of the most frequent tendon injuries in humans. However, there is no standard surgical technique thus far to reproduce complete rupture of this tendon in rats. Surgical procedures were performed in Wistar rats under light microscopy, with posterior longitudinal incision and preservation of the plantaris tendon. The animals were sacrificed on 2nd and 8th postoperative week and we used hematoxilin and eosin, picrosirius-red and Weigert’s resorcin-fuchsin to observe general tendon healing. The mean operative time was one minute and 24 seconds. Histological studies showed cellular proliferation and fibrillogenesis at two weeks, with decreased amounts of cellularity and elastic fibers at the 8th week, besides changes in structural organization of collagen fibers. The complete Achilles tenotomy in rats, was improved under light microscopy and sparing the plantaris tendon. This surgical technique was simple and quick, showed signs of normal healing process, could be easily reproducible, and triggered translational researches in this area.
文摘Background Tendon adhesion is one of the most common causes of disability following tendon surgery. Therefore, prevention of peritendinous adhesion after surgical repair of tendon is a major challenge. The aim of this study was to explore the possible application of a collagen membrane for the prevention or attenuation of peritendinous adhesions. Methods Sprague-Dawley (SD) rat Achilles tendon was cut and sutured by a modified Kessler's technique with or without the collagen membrane wrapped. Macroscopic, morphological and biomechanical evaluations were applied to examine the recovery of the injured tendon at 4 and 8 weeks after surgery. Results The surgery group wrapped by collagen membranes had a better outcome than the group with surgery repair only. In the collagen membrane-treated group, less adhesion appeared, stronger tensile strength was detected, and more tendon fibers and collagen I expression were observed morphologically. Conclusion Wrapping the tendon with a collagen membrane may be an efficient approach for tendon repair and preventing tendon adhesion after its ruptures.
