Çetin Işık, Mesut Tahta
PURPOSE: We aimed to present our novel technique in the surgical treatment of Achilles tendon avulsions and compare the clinical results of such technique with the repair method using suture anchors. METHODS: A retrospective study was made of patients with Achilles tendon sleeve avulsion and patients where distal portion of the tear prohibited primary repair, surgically treated between January 2009 and January 2013. Twenty-one patients who met the criteria were examined and called for final examination: 9 patients were treated with the novel technique (group 1) and 12 patients were treated with suture anchor repair (group 2)...

BACKGROUND: To study a hypothesis that the cost-effective 1.5cm medial incision Achilles tendon repair technique will provide good functional outcomes which are maintained for over 5 years. METHOD: Prospective study of 12 consecutive cases with a minimal 5-year follow-up were recruited from April 2008 to November 2010. Cases whom were mentally incompetent or those which required concomitant procedures were excluded. Outcomes measures included the numeric pain rating scale, motor power strength, range of motion, functional scoring using the AOFAS hindfoot score and patient's self-assessment using the Foot and Ankle Outcome Score (FAOS)...

We describe the diagnosis, treatment, rehabilitation, and complications of a 27-year-old male paraskiier who sustained a closed high-velocity knee dislocation after colliding with a tree at a speed of 45 mph and falling 40 feet to the ground. Extensive surgery to repair and reconstruct the knee included open lateral capsular repair, open anatomical posterolateral corner reconstruction with split Achilles tendon allograft, open iliotibial band reconstruction with Achilles tendon allograft, arthroscopic anterior cruciate ligament reconstruction with bone-patellar tendon-bone autograft, and double-bundle posterior cruciate ligament reconstruction with Achilles tendon allograft for the anterolateral bundle and tibialis anterior tendon allograft for the posteromedial bundle...

Tendon injuries are major musculoskeletal disorders. Polydeoxyribonucleotide activates the adenosine receptor subtype A2A, resulting in tissue growth and neogenesis. This experimental study confirms that polydeoxyribonucleotide can improve secretion of various growth factors, promote collagen synthesis, and restore tensile strength of the Achilles tendon in a rat model with Achilles tendon injury. Thirty-six male Sprague-Dawley rats, aged 7 weeks, were divided into two groups, and the Achilles tendon was transected and repaired using the modified Kessler's method...

INTRODUCTION: Numerous publications are dealing with acute Achilles tendon rupture. To our knowledge, no systematic trial has been published analyzing the incidence, risk factors and the potential clinical impact of postoperative tendon calcifications (PTC) after percutaneous Achilles tendon repair. Therefore, the aim of this study was to analyze these relevant aspects. MATERIALS AND METHODS: Between March 2003 and November 2010, a total of 126 patients with an acute, complete Achilles tendon rupture were treated with a percutaneous technique according to Ma and Griffith at a single university-based trauma department...

BACKGROUND AND AIM OF THE WORK: Achilles tendon rupture is frequent and can result in a disabling condition. The ideal method of management remains a matter of debate. We aimed to compare the clinical outcome of patients who underwent surgical repair of Achilles tendon rupture with Silfverskiöld augmentation technique with gastrocnemius fascia flap versus Krackow end-to-end stitching technique. METHODS: We retrospectively studied all patients that were surgically treated for Achilles tendon rupture at our institution, between January 2000 and December 2015, using either Silfverskiöld or Krackow technique...

BACKGROUND: The Achilles tendon, the largest and strongest tendon in the human body, is nevertheless one of the tendons which most commonly undergoes a complete subcutaneous tear. Achilles tendon ruptures are especially common in middle aged men who occasionally participate in sport. Even though Achilles tendon ruptures are frequent, up to 25% of acute injuries are misdiagnosed, and present as chronic injuries. METHODS: This is a review article about diagnosis and management of chronic Achilles tendon ruptures...

REVIEW
Rachel J Shakked, Steven M Raikin
Insertional Achilles tendinopathy is a degenerative enthesopathy associated with pain and dysfunction. Nonsurgical management is first attempted for a period of 3 to 6 months and may consist of physical therapy with eccentric training and other modalities. Surgical treatment can be successful with a variety of approaches. A thorough debridement through a midline tendon-splitting approach is associated with high satisfaction rates. Flexor hallucis longus transfer to augment the repair is considered in older, heavier patients or if more than 50% of the tendon was debrided...

REVIEW
Oliver Schipper, Bruce Cohen
Achilles tendon rupture is a common lower extremity injury seen in the active population. Although reruptures rates have improved with nonoperative functional management, surgical treatment is still preferred by the authors. Minimally invasive techniques allow optimal Achilles tendon rupture apposition and tensioning, with a reduced risk of soft tissue complications associated with the traditional open repair.

INTRODUCTION: Rupture of the Achilles' tendon is a common injury occurring particularly in middle-aged men due to sports trauma. Operative treatment is preferred generally due to lower risk of re-rupture. Possible complications of the operation include suture granulomas. Suture granulomas might represent a foreign body reaction, which itself is the end-stage response of the inflammatory wound-healing process to biomaterials. It may occur with both absorbable and non-absorbable suture materials such as silk in our case...

BACKGROUND: The Dresden technique preserves the paratenon during Achilles tendon repair and may improve the plantarflexor mechanism when combined with mobilization during early rehabilitation. However, the surgical repair design for Achilles tendon ruptures can affect rates of re-rupture or lengthening. Therefore, the aim of this study was to determine the biomechanical properties of the Krackow, Double-Kessler, Double-Dresden, and Triple-Dresden techniques used for repairing mid-substance Achilles tendon ruptures during cyclical and maximum traction...

Stem cells have been widely used in tendon tissue engineering. The lack of refined and controlled differentiation strategy hampers the tendon repair and regeneration. This study aims to find new effective differentiation factors for stepwise tenogenic differentiation. By microarray screening, the transcript factor Fos was found to be expressed in significantly higher amounts in postnatal Achilles tendon tissue derived from 1 day as compared with 7-days-old rats. It was further confirmed that expression of Fos decreased with time in postnatal rat Achilles tendon, which was accompanied with the decreased expression of multiply tendon markers...

Cell-based therapy hold great promise for tendon disorders, a widespread debilitating musculoskeletal condition. Even if the cell line remains to be defined, preliminary evidences have proven that amniotic-derived cells possess in vitro and in vivo a great tenogenic potential. The present study investigated the efficacy of transplanted human amniotic epithelial cells (hAECs) by testing their early regenerative properties and mechanisms involved on a validated ovine Achilles tendon partial defect performed on 29 animals...

Tenomodulin (Tnmd) is the best-known mature marker for tendon and ligament lineage cells. It is important for tendon maturation, running performance and has key implications for the resident tendon stem/progenitor cells (TSPCs). However, its exact functions during the tendon repair process still remain elusive. Here, we established an Achilles tendon injury model in a Tnmd knockout (Tnmd(-/-)) mouse line. Detailed analyses showed not only a very different scar organization with a clearly reduced cell proliferation and expression of certain tendon-related genes, but also increased cell apoptosis, adipocyte and blood vessel accumulation in the early phase of tendon healing compared with their wild-type (WT) littermates...

Tendon pathologies are a group of musculoskeletal conditions frequently seen in clinical practice. They can be broadly classified into traumatic, degenerative and overuse-related tendinopathies. Rotator cuff tears, Achilles tendinopathy and tennis elbow are common examples of these conditions. Conventional treatments have shown inconsistent outcomes and might fail to provide satisfactory clinical improvement. With the growing trend towards the use of mesenchymal stem cells (MSCs) in other branches of medicine, there is an increasing interest in treating tendon pathologies using the bone marrow MSC...

Achilles tendon tear is common and increasingly frequent. Magnetic resonance imaging (MRI) is the modality of choice for radiological evaluation. It is accurate to assess the status and integrity of the tendon with well documented features. In this article, the MR findings of a normal Achilles tendon as well as common diseases like insertional and noninsertional tendinosis, chronic tendinosis with marked lengthening, tendon rupture are illustrated. After a torn Achilles tendon receives surgical repair, it undergoes different stages of healing process including inflammatory, reparative and remodeling phases...

The retro-calcaneal bursa presents a synovial and a non-synovial osseous part of variable dimensions. Studies objectively measuring the variability of the size of this osseous bursal surface cannot be found in literature. The objective of this study was to investigate (i) the dimension variability of the bony part of the bursa and (ii) the relationship of this surface to other articulating areas of the calcaneus. A digital planimeter was used to measure the bursae (n=86) and other articular surface areas of the calcaneus and statistically compared with ANOVA and correlation estimations...

Poor tendon repair is often a clinical challenge due to the lack of ideal biomaterials. Electrospun aligned fibers, resembling the ultrastructure of tendon, have been previously reported to promote tenogenesis. However, the underlying mechanism is unclear and the aligned fibers alone are not capable enough to commit teno-differentiation of stem cells. Here, based on our observation of reduced expression of histone deacetylases (HDACs) in tendon stem/progenitor cells (TSPCs) cultured on aligned fibers, we proposed a strategy to enhance the tenogenesis effect of aligned fibers by using a small molecule Trichostatin A (TSA), an HDAC inhibitor...

BACKGROUND: Several single-nucleotide polymorphisms (SNPs) in the TNC gene have recently been found to be associated with degenerative rotator cuff tears. HYPOTHESIS: Exonic SNPs in the TNC gene are related to the risk for a failure to heal after rotator cuff repair. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: A total of 302 patients from the Vienna area and European Caucasian ancestry underwent mini-open rotator cuff repair for a full-thickness superior or posterosuperior tear and were assessed for the integrity of the repair 1 year postoperatively with a real-time 7...
