Abstract
BACKGROUND At present, it is unclear which is the best management for Achilles tendon rupture. PURPOSE We assess the clinical, functional and imaging outcomes of active patients undergoing 3 different types of management for acute subcutaneous rupture of the Achilles tendon, including conservative cast immobilization, traditional open surgery and percutaneous repair. METHODS 26 active patients were managed for a rupture of the Achilles Tendon from January 2007 to March 2008. Anthropometric measurements, Functional assessment, Isometric strength, Ultrasonographic assessment, Patient satisfaction, Working life, Physical activity, Functional score and Complications were recorded retrospectively. RESULTS All 23 (21 men, 2 women) patients were reviewed at a minimum follow-up of 24 months (average 25.7, range 24 to 32 months, SD: 6.3) from the index injury. Thermann scores and patient satisfaction were significantly higher following surgery than conservative management with no significance between open and minimally invasive operated patients. Sensitive disturbances occur in up to 12% of open repairs and 1.8% of patients managed nonsurgically. CONCLUSIONS Clinical and functional outcomes following surgical repair, percutaneous and open, of the Achilles tendon are significantly improved than following conservative management. LEVEL OF EVIDENCE Level III.

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.

Biological strategies to enhance healing of the avascular area of the meniscus. Stem Cells Int 2011; 2012:528359. [PMID: 22220179 PMCID: PMC3246301 DOI: 10.1155/2012/528359] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2011] [Accepted: 11/01/2011] [Indexed: 12/15/2022] Open
Abstract
Meniscal injuries in the vascularized peripheral part of the meniscus have a better healing potential than tears in the central avascular zone because meniscal healing principally depends on its vascular supply. Several biological strategies have been proposed to enhance healing of the avascular area of the meniscus: abrasion therapy, fibrin clot, organ culture, cell therapy, and applications of growth factors. However, data are too heterogeneous to achieve definitive conclusions on the use of these techniques for routine management of meniscal lesions. Although most preclinical and clinical studies are very promising, they are still at an experimental stage. More prospective randomised controlled trials are needed to compare the different techniques for clinical results, applicability, and cost-effectiveness.

Abstract
Tissue engineering techniques using novel scaffold materials offer potential alternatives for managing tendon disorders. Tissue engineering strategies to improve tendon repair healing include the use of scaffolds, growth factors, cell seeding, or a combination of these approaches. Scaffolds have been the most common strategy investigated to date. Available scaffolds for tendon repair include both biological scaffolds, obtained from mammalian tissues, and synthetic scaffolds, manufactured from chemical compounds. Preliminary studies support the idea that scaffolds can provide an alternative for tendon augmentation with an enormous therapeutic potential. However, available data are lacking to allow definitive conclusion on the use of scaffolds for tendon augmentation. We review the current basic science and clinical understanding in the field of scaffolds and tissue engineering for tendon repair.

Abstract
Skeletal muscle injuries are common in athletes, occurring with direct and indirect mechanisms and marked residual effects, such as severe long-term pain and physical disability. Current therapy consists of conservative management including RICE protocol (rest, ice, compression and elevation), nonsteroidal anti-inflammatory drugs, and intramuscular corticosteroids. However, current management of muscle injuries often does not provide optimal restoration to preinjury status. New biological therapies, such as injection of platelet-rich plasma and stem-cell-based therapy, are appealing. Although some studies support PRP application in muscle-injury management, reasons for concern persist, and further research is required for a standardized and safe use of PRP in clinical practice. The role of stem cells needs to be confirmed, as studies are still limited and inconsistent. Further research is needed to identify mechanisms involved in muscle regeneration and in survival, proliferation, and differentiation of stem cells.

Tissue engineering for rotator cuff repair: an evidence-based systematic review. Stem Cells Int 2011; 2012:418086.

Abstract
The purpose of this systematic review was to address the treatment of rotator cuff tears by applying tissue engineering approaches to improve tendon healing, specifically platelet rich plasma (PRP) augmentation, stem cells, and scaffolds. Our systematic search was performed using the combination of the following terms: “rotator cuff”, “shoulder”, “PRP”, “platelet rich plasma”, “stemcells”, “scaffold”, “growth factors”, and “tissue engineering”. No level I or II studies were found on the use of scaffolds and stem cells for rotator cuff repair. Three studies compared rotator cuff repair with or without PRP augmentation. All authors performed arthroscopic rotator cuff repair with different techniques of suture anchor fixation and different PRP augmentation. The three studies found no difference in clinical rating scales and functional outcomes between PRP and control groups. Only one study showed clinical statistically significant difference between the two groups at the 3-month follow up. Any statistically significant difference in the rates of tendon rerupture between the control group and the PRP group was found using the magnetic resonance imaging. The current literature on tissue engineering application for rotator cuff repair is scanty. Comparative studies included in this review suggest that PRP augmented repair of a rotator cuff does not yield improved functional and clinical outcome compared with non-augmented repair at a medium and long-term followup.

Abstract
A laboratory study was performed to evaluate the histopathological features of the macroscopically intact portion of the Achilles tendon in patients undergoing surgery for an acute rupture of the Achilles tendon. Tendon samples were harvested from 29 individuals (21 men, 8 women; mean age: 46 ± 12) who underwent repair of an Achilles tendon tear tear, and from 11 male patients who died of cardiovascular events (mean age: 61). Three pieces of tendon were harvested: at the rupture site, 4 cm proximal to the site of rupture, 1 cm proximal to the insertion of the Achilles tendon on the calcaneum. Slides were assessed using a semiquantitative grading scale assessing fiber structure and arrangement, rounding of the nuclei, regional variations in cellularity, increased vascularity, decreased collagen stainability, and hyalinization. Intra-observer reliability of the subscore readings was calculated. The pathological features were significantly more pronounced in the samples taken from the site of rupture than in the samples taken proximally and distal to it (0.008 < P < 0.01). There were no significant differences in the mean pathologic sum-scores in the samples taken proximally and distal to the site of rupture. Unruptured Achilles tendons, even at an advanced age, and ruptured Achilles tendons are clearly part of two distinct populations, with the latter demonstrating histopathological evidence of failed healing response even in areas macroscopically normal.

Abstract
IMPORTANCE OF THE FIELD Tendon disorders are frequent and are responsible for much morbidity, both in sport and the workplace. Although several therapeutic options are routinely used, very few well-conducted randomised prospective, placebo, controlled trials have been performed to assist in choosing the best evidence-based management. AREAS COVERED IN THIS REVIEW We performed a comprehensive search of PubMed, Medline, Cochrane, CINAHL, and Embase databases over the years 1966 - 2010 to review the best evidence-based options for the management of patients with tendinopathy. WHAT THE READER WILL GAIN The reader will obtain information on the available medical and surgical therapies used to manage tendinopathy-related symptoms. The effectiveness of therapies, the length of management and the adverse effects are examined. TAKE-HOME MESSAGE Management of tendinopathy is often anecdotic and lacking well-researched scientific evidence. Teaching patients to control the symptoms may be more beneficial than leading them to believe that tendinopathy is fully curable.

Abstract
INTRODUCTION Tendon injuries give rise to significant morbidity. In the last few decades, several techniques have been increasingly used to optimize tendon healing. SOURCES OF DATA We performed a comprehensive search of PubMed, Medline, Cochrane, CINAHL and Embase databases using various combinations of the commercial names of each scaffold and the keywords 'tendon', 'rotator cuff', 'supraspinatus tendon', 'Achilles tendon', 'growth factors', 'cytokines', 'gene therapy', 'tissue engineering', 'mesenchymal' and 'stem cells' over the years 1966-2009. All articles relevant to the subject were retrieved, and their bibliographies were hand searched for further references in the context to tissue-engineered biological augmentation for tendon healing. AREAS OF AGREEMENT Several new techniques are available for tissue-engineered biological augmentation for tendon healing, growth factors, gene therapy and mesenchimal stem cells. AREAS OF CONTROVERSY Data are lacking to allow definitive conclusions on the use of these techniques for routine management of tendon ailments. GROWING POINTS The emerging field of tissue engineering holds the promise to use new techniques for tendon augmentation and repair. Preliminary studies support the idea that these techniques can provide an alternative for tendon augmentation with great therapeutic potential. AREAS TIMELY FOR DEVELOPING RESEARCH The optimization strategies discussed in this article are currently at an early stage of development. Although these emerging technologies may develop into substantial clinical treatment options, their full impact needs to be critically evaluated in a scientific fashion.

Abstract
Minimally invasive techniques for hallux valgus correction include arthroscopy, percutaneous and minimum incision surgery. In the last few decades, several techniques have been increasingly used. We performed a comprehensive search of CINAHL, Embase, Medline, HealthSTAR and the Cochrane Central Registry of Controlled Trials, from inception of the database to 4 January 2010, using various combinations of the keywords terms 'Bosch', 'PDO', 'percutaneous distal osteotomy', 'SERI', 'percutaneous', 'minimal incision', 'minimum incision', 'minimally invasive', 'less invasive', 'mini-invasive', 'hallux valgus', 'bunion', 'surgery', 'arthroscopy', 'metatarsal' 'forefoot'. Only articles published in peer reviewed journals were included in this systematic review. Several new techniques are available for minimally invasive correction of the hallux valgus. Minimally invasive correction of the hallux valgus may provide better outcome for patients who would not recover well from traditional open approaches, because of decreasing recovery and rehabilitation times, as surgical exposure and deep tissue dissection are smaller and gentler to the soft tissues. Data are lacking to allow definitive conclusions on the use of these techniques for routine management of patients with hallux valgus. Given the limitations of the current case series, especially the extensive clinical heterogeneity, it is not possible to determine clear recommendations regarding the systematic use of minimally invasive surgery for hallux valgus correction, even though preliminary results are encouraging. Studies of higher levels of evidence, concentrating on large adequately powered randomized trials, should be conducted to help answer these questions.

Abstract
BACKGROUND The management of Achilles tendon (AT) ruptures in elite athletes can be challenging. We performed a retrospective review of prospectively collected data study to evaluate the results of percutaneous repair of an acute AT rupture in elite athletes. MATERIALS AND METHODS Seventeen elite athletes with prodromal tendinous problems sustained an acute tear of the AT and underwent percutaneous surgical repair. We performed preoperative evaluations the day of surgery, and report the results of postoperative evaluation at a final followup at an average of 72 months from the procedure. Each patient was evaluated for limb dominance, trauma history, duration and type of preoperative symptoms, and postoperative AT Total Rupture Score (ATRS). RESULTS All patients were able to fully weightbear on the operated limb by the end of the 8th postoperative week. The average time to return to full sport participation was 4.8±0.9 months. Two of the 15 elite athletes on whom we have full data suffered from a superficial infection of the surgical wound. CONCLUSION Our study suggests that percutaneous repair of the AT is a good option for elite athletes, allowing a safe and prompt return to sport activities.

Abstract
Minimally invasive trauma and orthopedic surgery is increasingly common, though technically demanding. Its use for pathologies of the Achilles tendon (AT) hold the promise to allow faster recovery times, shorter hospital stays, and improved functional outcomes when compared to traditional open procedures, which can lead to difficulty with wound healing because of the tenuous blood supply and increased chance of wound breakdown and infection. We present the recent advances in the field of minimally invasive AT surgery for tendinopathy, acute ruptures, chronic tears, and chronic avulsions of the AT. In our hands, minimally invasive surgery has provided similar results to those obtained with open surgery, with decreased perioperative morbidity, decreased duration of hospital stay, and reduced costs. So far, the studies on minimally invasive orthopedic techniques are of moderate scientific quality with short follow-up periods. Multicenter studies with longer follow-up are needed to justify the long-term advantages of these techniques over traditional ones.
