Achilles tendinosis is primarily managed nonoperatively with activity modification and physiotherapy, although surgery can be required. This has classically involved surgical decompression of the Achilles tendon, although the use of radiofrequency microdebridement has been suggested as a novel minimally invasive alternative. We present a randomized controlled trial comparing radiofrequency microdebridement using the Topaz® microdebrider wand and traditional surgical decompression. All patients with Achilles tendinosis referred to a single surgeon and meeting the inclusion criteria were invited to participate in our single-blinded, randomized controlled study...

BACKGROUND: Limited ankle dorsiflexion has been implicated as a contributing factor to plantar ulceration of the forefoot in diabetes mellitus. The purpose of this study was to compare outcomes for patients with diabetes mellitus and a neuropathic plantar ulcer treated with a total-contact cast with and without an Achilles tendon lengthening. Our primary hypothesis was that the Achilles tendon lengthening would lead to a lower rate of ulcer recurrence. METHODS: Sixty-four subjects were randomized into two treatment groups, immobilization in a total-contact cast alone or combined with percutaneous Achilles tendon lengthening, with measurements made before and after treatment, at the seven-month follow-up examination, and at the final follow-up evaluation (a mean [and standard deviation] of 2...

The purpose of the present study was to investigate the long-term effect of deep infection, sural nerve injury, and repeat rupture in the treatment of acute Achilles tendon rupture. A total of 324 patients had made a claim to the Danish Patient Insurance Association from 1992 to 2010 for a complication after acute Achilles tendon rupture. Of the 324 patients, 119 (36.7%) (77 [64.7%] males and 42 [35.3%] females) returned the Achilles tendon total rupture score and the 36-item short-form survey questionnaires...

Percutaneous Achilles tendon lengthening can result in Achilles tendon rupture. This complication has been controversially linked to torsion effects in the Achilles tendon. Routine percutaneous triple-hemisection techniques (group A), rotary triple-hemisection (group B), distal double-hemisection (group C), and proximal double-hemisection (group D) were compared in cadaveric specimens to provide insights into the mechanism of uneven incision lengthening and inadvertent Achilles tendon rupture. The degree of Achilles tendon torsion on various planes was measured in 20 lower limb pairs from fresh cadavers...

Repair of chronic Achilles tendon rupture is a surgical challenge. We describe the use of a free turndown tendon flap augmentation raised from the proximal gastrocnemius aponeurosis. To control optimal tension or the reconstructed Achilles tendon length, we used an original method by referring to the gravity planter flexion ankle angle of the contralateral limb. Key aspects of the technique are described. A retrospective analysis of the short-term outcomes achieved in a case series (n = 56) is presented. The postoperative anthropometric findings are also presented to indicate the successful outcomes achieved with this technique...

PURPOSE: The purpose of this study was to establish a relationship between the lengthening of the Achilles tendon post-rupture and surgical repair to muscle activation patterns during walking in order to serve as a reference for post-surgical assessment. METHOD: The Achilles tendon lengths were collected from 4 patients with an Achilles tendon rupture 6 and 12 months post-surgery along with 5 healthy controls via ultrasound. EMG was collected from the triceps surae muscles and tibialis anterior during overground walking...

A large number of tendon repair techniques have been described for acute tendon injury. However, after reviewing the literature, it was noted that there were limited descriptions of specific suture techniques that address repair processes of chronic tendon pathology. Generally, in chronic tendinopathy, others have described a process known as tendon tubularization, which consists of a running stitch using a nonabsorbable suture material along the external surface of the tendon. We believe that leaving a nonabsorbable suture on the exterior surface of the tendon in this manner has the potential to disrupt the optimal gliding function...

BACKGROUND: To date, studies directly comparing the rerupture rate in patients with an Achilles tendon rupture who are treated with surgical repair with the rate in patients treated nonoperatively have been inconclusive but the pooled relative risk of rerupture favored surgical repair. In all but one study, the limb was immobilized for six to eight weeks. Published studies of animals and humans have shown a benefit of early functional stimulus to healing tendons. The purpose of the present study was to compare the outcomes of patients with an acute Achilles tendon rupture treated with operative repair and accelerated functional rehabilitation with the outcomes of similar patients treated with accelerated functional rehabilitation alone...

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...

BACKGROUND: Dynamic rehabilitation has been suggested to be an important part of nonoperative treatment of acute Achilles tendon rupture that results in functional outcome and rerupture rates comparable with those of operative treatment. However, the optimal role of weight-bearing during early rehabilitation remains unclear. The purpose of this study was to compare immediate weight-bearing with non-weight-bearing in a nonoperative dynamic treatment protocol for Achilles tendon rupture...

Increased tendon stiffness in response to mechanical loading is well established in young animals. Given that tendons stiffen with aging, we aimed to determine the effect of increased loading on tendons of old animals. We subjected 28-month-old mice to 10 weeks of uphill treadmill running; sedentary 8- and 28-month-old mice served as controls. Following training, plantaris tendon stiffness and modulus were reduced by approximately half, such that the values were not different from those of tendons from adult sedentary animals...

PURPOSE: The purpose of this study was to compare outcomes of different minimally invasive techniques for reconstruction of Achilles tendon re-ruptures. METHODS: We prospectively enrolled 21 patients undergoing minimally invasive reconstruction using a transfer of the ipsilateral peroneus brevis (PB) (five patients) or the free ipsilateral semitendinosus tendon (ST) graft with or without interference screw fixation (ten and six patients, respectively). We assessed the maximum calf circumference and isometric plantar flexion strength before surgery and at the last follow up...

BACKGROUND: Whether the human Achilles tendon undergoes hypertrophic changes as measured by an increase in cross-sectional area, in response to endurance training exercise remains in question. We investigated the hypothesis that transition from civilian life through 6 months of elite infantry training would induce adaptive Achilles tendon hypertrophy. METHODS: Seventy-two new elite infantry recruits had the cross-sectional area of their Achilles tendons measured at a point 2...

Early motion of a repaired Achilles tendon has been accepted to improve both clinical and biomechanical outcomes. It has been postulated that augmenting a primary Achilles tendon repair with a collagen ribbon will improve the repair construct's initial strength, thereby facilitating early motion. The purpose of the present study was to compare the failure load of Achilles tendon defects repaired with suture, with or without augmentation with a collagen ribbon. Ten matched pairs of cadaveric feet and tibiae underwent simulated Achilles tendon tear in the watershed area and were then repaired with 4-strand Krackow sutures only or were sutured and augmented with a box weave collagen ribbon xenograft...

The Achilles tendon is the strongest tendon in the human body and, as such, has its share of problems. Although many conditions affecting this tendon can be treated nonoperatively, surgical intervention is often necessary. Local, regional, distant, and allograft tendon can be used to supplement or enhance reconstruction or repair of the Achilles tendon. Specific techniques are explored and described and the published results from the literature summarized. This article explores the use of tendon transfers and supplementation in the treatment of insertional and noninsertional Achilles tendinosis as well as in cases of neglected or chronic ruptures of the tendoachilles...

PURPOSE: Recent studies using ultrasonography have demonstrated that training-induced changes in the mechanical properties of tendons in plantar flexors (i.e., Achilles tendon) are lower than those in knee extensors (i.e., patellar tendon). However, the mechanisms for these phenomena are unknown. The purpose of this study was to compare changes in blood circulation of patellar and Achilles tendons by repeated muscle contractions and heating. METHODS: Eleven healthy males participated in this study...

BACKGROUND: Chronic tears of the Achilles tendon can result in substantial loss of function. Those tears with a tendon gap of up to 6.5 cm can be treated surgically with use of an autologous peroneus brevis tendon graft. METHODS: At an average follow-up period of 15.5 years after the surgery, we examined sixteen of twenty-two patients who had undergone peroneus brevis tendon graft reconstruction for a chronic Achilles tendon tear. Clinical and functional assessment was performed...

PURPOSE: Achilles and patellar tendinopathy cause significant morbidity in professional and recreational athletes. Both the Achilles and patellar tendons are weight-bearing tendons that lack a true tendon sheath but are surrounded by paratenon. METHOD: A review of the literature to outline the characteristics of tendinopathy in these two tendons, and to discuss current concepts of pathophysiology, use of imaging in the diagnosis and aid to clinical management strategies in tendinopathy...
