[PMID: 38296758 DOI: 10.1016/j.fas.2024.01.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 09/06/2023] [Accepted: 01/13/2024] [Indexed: 02/02/2024]
Abstract
BACKGROUND Injections around the Achilles tendon (AT) are commonly performed in clinical practice to manage non-insertional Achilles tendinopathy, but the presence/distribution of the injectate with relation to its sheath has not been assessed specifically. Accordingly, the aim of this cadaveric investigation was to demonstrate the feasibility of Achilles paratenon injection under ultrasound guidance - by confirming the exact needle positioning as well as the dye distribution inside the paratenon lumen. METHODS A descriptive laboratory study with three human cadaveric specimens (one fresh cadaver and two cadavers embalmed using the Fix for Life (F4L) method) was performed in a tertiary-care academic institution. The interventional technique and the related anatomical findings were illustrated. During the injection, the needle was advanced inside the Achilles paratenon under ultrasound guidance i.e. in-plane medial-to-lateral approach. With the objective to confirm its correct placement, the needle was kept in situ on the right AT of the fresh cadaver. Likewise, to demonstrate the location of the dye inside the lumen of Achilles paratenon, the other five ATs - four on the embalmed cadavers and one on the fresh cadaver - were injected with 5 mL of green color dye. After removal of the needle, a layer-by-layer anatomical dissection was performed on all three cadavers. RESULTS On the right AT of the fresh cadaver, the position of the needle's tip within the Achilles paratenon was confirmed. Accurate placement of the dye inside the paratenon lumen was confirmed in four (80%) ATs, one of the fresh and three of the embalmed cadavers. No spread inside the crural fascia compartment or between the AT and the Kager's fat pad was observed. Herewith, unintentional spilling of the dye within the superficial soft tissues of the posterior leg was reported in the left AT of one of the two embalmed cadavers (20%). CONCLUSIONS Ultrasound-guided injection using the in-plane, medial-to-lateral approach can accurately target the lumen of Achilles paratenon.

Abstract
PURPOSE This study was aimed to review the short-term results of endoscopic percutaneous longitudinal tenotomy for noninsertional Achilles tendinopathy using the Centerline Endoscopic Carpal Tunnel Release instrument (Arthrex). This method simplifies the operation technique, allows a good endoscopic visualisation of the Achilles tendon with very promising results. METHODS We performed multiple percutaneous longitudinal tenotomies under local anesthesia in 24 patients (25 tendons) with Achilles tendinopathy or peritendinitis that had failed conservative treatment between January 2013 and September 2016. All ambulatory procedures consisted of paratenon release and longitudinal tenotomies. The results were reviewed in 22 patients (23 tendons) at an average follow-up period of 22.5 months (range 10-36 months). Patients' satisfaction and functional outcomes were evaluated using the Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire, the pain visual analog scale (VAS), and the functional foot index. RESULTS Initial results are very promising with excellent results in 12 patients, good results in 9 patients, and fair result in 1 patient. One patient developed a postoperative thrombosis of the operated limb. Another patient developed a hypertrophic painful scar of the incision wound. The VAS for pain decreased drastically after the index procedure and averaged to 0.2 (SD 0.447). The VISA-A questionnaire score had improved from 42 ± 7.2 points preoperatively to 96.8 ± 14.3 points postoperatively (P = .004). The functional foot index decreased from 84 (SD 30.517) to 33.4 (SD 6.452) on the follow-up examination. CONCLUSIONS The endoscopic-assisted longitudinal tenotomies procedure of the Achilles tendon is easily feasible and can be performed on an outpatient basis, produces minimal complications and shows excellent results. The described technique is recommended for all surgeons especially for those familiar with endoscopy of the Achilles tendon. LEVELS OF EVIDENCE Therapeutic, Level IV: Case Series.

Abstract
Due to the increasing age of our society and a rise in engagement of young people in extreme and/or competitive sports, both tendinopathies and tendon ruptures present a clinical and financial challenge. Tendon has limited natural healing capacity and often responds poorly to treatments, hence it requires prolonged rehabilitation in most cases. Till today, none of the therapeutic options has provided successful long-term solutions, meaning that repaired tendons do not recover their complete strength and functionality. Our understanding of tendon biology and healing increases only slowly and the development of new treatment options is insufficient. In this review, following discussion on tendon structure, healing and the clinical relevance of tendon injury, we aim to elucidate the role of stem cells in tendon healing and discuss new possibilities to enhance stem cell treatment of injured tendon. To date, studies mainly apply stem cells, often in combination with scaffolds or growth factors, to surgically created tendon defects. Deeper understanding of how stem cells and vasculature in the healing tendon react to growth factors, common drugs used to treat injured tendons and promising cellular boosters could help to develop new and more efficient ways to manage tendon injuries.

Abstract
Achilles tendinopathy is a common clinical condition. The aetiology of Achilles tendinopathy remains unclear, but is probably multifactorial resulting from a combination of intrinsic and extrinsic factors. Excessive loading of the tendon during vigorous training activities is regarded as the main pathological stimulus. The Achilles tendon may respond to repetitive overload beyond physiological threshold by either inflammation of its sheath, degeneration of its body, or a combination of both. Conservative management, including relative rest, anti-inflammatory drugs, physiotherapy and orthoses may be beneficial. Surgery is generally recommended after exhausting conservative management, usually after at least three to six months. Long-standing Achilles tendinopathy is associated with poor postoperative results, with a greater rate of reoperation before reaching an acceptable outcome.

Abstract
Ultrasonography was performed on the Achilles tendon of the dominant limb of 18 male elderly athletes and 11 sedentary men, aged 70 to 80 years. The tendons were examined with a real-time linear array scanner using a 7.5 MHz transducer. Both longitudinal and transverse images were taken. The mean width of the Achilles tendon was significantly larger in the athletes than in the control subjects. The tendon thickness and cross-sectional area did not differ significantly between the groups, but the figures may indicate a tendency for larger cross-sectional area in the athletes. The results suggest tendon hypertrophy following long-term training.

Abstract
Synopsis Tendinopathy has become the accepted term to describe a spectrum of changes that occur in damaged and/or diseased tendons. Over the past 2 decades, there have been new insights into tendon pathophysiology of relevance to clinicians, including (1) better characterization of the overuse injury process and the resultant structural and functional disruption in chronically painful tendons, (2) improved understanding of the pathomechanics associated with chronic tendon injury, and (3) greater knowledge about the influence of lifestyle factors and drugs on tendon pathology. The implications of these new insights are discussed. J Orthop Sports Phys Ther 2015;45(11):833-841. Epub 21 Sep 2015. doi:10.2519/jospt.2015.5884.

Abstract
Abstract
Disorders of the Achilles tendon, the largest tendon in the human body, are common and occur in both active and sedentary persons. A thorough history and physical examination allow primary care physicians to make an accurate diagnosis and to initiate appropriate management. Mismanaged or neglected injuries markedly decrease a patient’s quality of life. A growing body of related literature is the basis for current therapeutic regimens, which use a multimodal conservative approach, including osteopathic manipulative treatment. Although primary care physicians can manage most cases of Achilles tendon disorders, specialty care may be needed in certain instances. Procedural intervention should consider any comorbid conditions in addition to patients’ lifestyle to help guide decision making. When appropriately managed, Achilles tendon disorders generally carry a favorable prognosis.

Abstract
OBJECTIVE Glucocorticoid injections are used by rheumatologists to treat chronic tendinopathy. Surprisingly, the mechanisms by which corticosteroids induce pain relief in this condition have not been investigated. Previous studies have shown local substance P (SP) levels to be correlated with tendon pain and tissue pathology. The objective of this study was to determine whether SP production in human tenocytes is modulated by exposure to dexamethasone. METHODS Human tendon fibroblasts were cultured in the presence or absence of dexamethasone (1-400 nM), an inhibitor of the glucocorticoid receptor, RU486, recombinant TGF-β (2.5 or 5.0 ng/ml) or an inhibitor of the TGF-β receptor (A83.01), recombinant human IL-1β and IL-6. Expression levels of the genes encoding for SP (TAC1) and its preferred receptor (NK1R), IL-1α, IL-1β and IL-6 were determined with quantitative PCR and protein levels of SP were examined by EIA and western blot. RESULTS Exposure of human tendon cells to dexamethasone resulted in a time-dependent reduction of mRNA for SP in both hamstrings and Achilles tenocytes, whereas NK1R was unaffected. The reduction of SP mRNA was dependent on signalling through the glucocorticoid receptor. SP protein was substantially decreased by dexamethasone. Dexamethasone also prevented induction of SP by IL-1β and by cyclic mechanical loading. CONCLUSION This study demonstrates that dexamethasone treatment of human tendon fibroblasts reduces the expression of SP through a glucocorticoid receptor-dependent pathway. Drugs interfering with SP signalling could be a future target in the treatment of tendinopathy.

Abstract
Achilles tendon disorders include tendinosis, paratenonitis, insertional tendinitis, retrocalcaneal bursitis, and frank rupture. Patients present with pain and swelling in the posterior aspect of the ankle. Magnetic resonance imaging and ultrasound are helpful in confirming the diagnosis and guiding treatment. Nonsurgical management of Achilles tendon disorders includes nonsteroidal anti-inflammatory drugs, physical therapy, bracing, and footwear modification. Surgical treatment includes debridement of the diseased area of the tendon with direct repair. Tendon transfer may be necessary to augment the strength of the Achilles tendon.

Abstract
BACKGROUND Multiple percutaneous longitudinal tenotomies have been successfully undertaken in runners with isolated midportion Achilles tendinopathy (nodular lesions <2.5 cm) without any sign of paratendinopathy. HYPOTHESIS In the long term, minimally invasive multiple tenotomies allow the patient to remain involved in middle- and long-distance running. Clinical and ultrasound (US) evidence of paratendinopathy is a negative prognostic factor. STUDY DESIGN Case series study; Level of evidence, 4. METHODS A total of 39 patients were reviewed at an average follow-up of 17 years (range, 15-22 years) after US-guided multiple percutaneous longitudinal tenotomies for chronic Achilles tendinopathy. The Victorian Institute of Sports Assessment-Achilles (VISA-A) questionnaire was completed by each patient, maximum calf circumference and isometric plantarflexion strength of the gastrocsoleus complex were measured in both the affected and contralateral legs, and functional assessment was scored by the 4-point Boyden scale. Achilles tendon changes were also assessed according to the grayscale US grading system. RESULTS At the final follow-up, the maximum calf circumference and the strength in the operated leg were not significantly different than those measured preoperatively, but they were significantly lower than those on the contralateral side. This did not affect patients' daily or sports activities. All patients had returned to their preinjury working occupation; 20 patients were still active in middle- and long-distance running, with an average current level of sport and function that was 60% ± 13% compared with baseline status (before onset of symptoms). Thirty of 39 patients (77%) reported good or excellent outcomes according to the Boyden assessment. On US assessment, the tendon was generally thicker than the contralateral asymptomatic tendon (average, 7.0 vs 8.7 mm, respectively; P = .003). There was no significant difference (P > .05) when comparing patients with good or excellent Boyden results versus those with fair or poor outcomes. The mean VISA-A score was 78.5, with no significant difference between patients with and without paratendinopathy on US assessment (P > .05). All of the patients who did not return to running or who gave up sports activities had signs of paratendinopathy. CONCLUSION This approach to the management of midportion Achilles tendinopathy is safe, has a low cost, and is effective in the long term.

Abstract
This is a prospective analysis on 30 physically active individuals with a mean age of 48.9 years (35 to 64) with chronic insertional tendinopathy of the tendo Achillis. Using a transverse incision, the tendon was debrided and an osteotomy of the posterosuperior corner of the calcaneus was performed in all patients. At a minimum post-operative follow-up of three years, the Victorian Institute of Sports Assessment scale – Achilles tendon scores were significantly improved compared to the baseline status. In two patients a superficial infection of the wound developed which resolved on antibiotics. There were no other wound complications, no nerve related complications, and no secondary avulsions of the tendo Achillis. In all, 26 patients had returned to their pre-injury level of activity and the remaining four modified their sporting activity. At the last appointment, the mean pain threshold and the mean post-operative tenderness were also significantly improved from the baseline (p < 0.001). In patients with insertional tendo Achillis a transverse incision allows a wide exposure and adequate debridement of the tendo Achillis insertion, less soft-tissue injury from aggressive retraction and a safe osteotomy of the posterosuperior corner of the calcaneum.

Abstract
BACKGROUND Non-insertional Achilles tendinopathy is an increasing, perhaps secondary to an increase in sporting activities. Traditional open surgical procedures have been associated with a significant rate of complications. We describe a minimally invasive technique involving the release of the adherent paratenon with a peritendinous infusion of corticosteroids and present the results in a cohort of patients. MATERIALS AND METHODS Twenty-nine tendons (26 patients) with non-insertional Achilles tendinopathy were treated with the above technique. Assessments were made prospectively using an adapted classification of Achilles tendon disability and a visual analogue scale for pain. Patients were interviewed in person or by telephone at an average of 14 (range, 6 to 30) months after surgery. RESULTS The average pain score (VAS) improved from 8.7 to 2.4 (p < 0.001) and the average Puddu level of disability improved from 4.9 to 1.7 (p < 0.001). Seventy-five percent of patients had a good or excellent outcome with 20% having sufficient improvement not to pursue further medical attention for their tendinopathy. There was a 7% rate of minor complications due to delayed wound healing which resolved spontaneously and did not affect the rehabilitation or the recovery of the patients. CONCLUSION A minimally invasive circumferential paratenon release and peritendinous steroid infusion was a simple method to treat non-insertional Achilles tendinopathy and had low morbidity in our series. This technique has become our preferred primary surgical intervention for this condition.

Abstract
Chronic Achilles tendon disorders range from overuse syndromes to frank ruptures. Numerous forms of treatment have been used, depending on the nature of the disorder or injury. Ultrasonography and magnetic resonance imaging are commonly used for evaluation. The spectrum of disease comprises paratenonitis, tendinosis, paratenonitis with tendinosis, retrocalcaneal bursitis, insertional tendinosis, and chronic rupture. However, there is no clear consensus on what defines a chronic Achilles disorder. Nonsurgical therapy is the mainstay of treatment for most patients with overuse syndromes. Surgical techniques for overuse syndromes or chronic rupture include débridement, local tissue transfer, augmentation, and synthetic grafts. Local tissue transfer most commonly employs either the flexor hallucis longus or flexor digitorum longus tendon to treat a chronic rupture. Reports on long-term outcomes are needed before useful generalizations can be made regarding treatment.

Abstract
Overuse tendinopathy remains a major clinical burden for sports medicine and general practitioners. Recent studies have highlighted the role of sensory and autonomic nerves in generating or perpetuating the symptoms and tissue abnormalities associated with tendinopathy. We outline the neuroanatomy and potential roles of nerves and associated neuropeptides in tendinopathy. In addition, intriguing new data is reviewed which suggests that there may be a substantial intrinsic source of neuropeptides within tendons - namely, the tenocytes themselves. The potential roles of Substance P and mast cells are highlighted in particular. We discuss the implications for conservative management including sclerosing injections and exercise training.

Abstract
Background About 10% of patients not responding to 3–6 months of conservative management for insertional Achilles tendinopathy undergo surgery. Traditionally, surgery of the Achilles tendon is performed through longitudinal extensile incisions. Such surgery is prone to the complications of wound healing, wound breakdown and iatrogenic nerve injury. Methods We describe our current method of exposure of the Achilles tendon insertion and debridement of the peritendinous and tendon tissue with osteotomy of the calcaneum through a transverse skin incision at the level of the Achilles insertion. Results This method has been used since 2002 on over 40 patients for exposure of the Achilles tendon insertion and the distal Achilles tendon. Conclusion The Cincinnati incision allows adequate exposure, has minimal risk of symptomatic iatrogenic nerve injury, and has minimal problems related to the scar.

Abstract
Because most Achilles tendon injuries take place in sports and there has been a general increase in the popularity of sporting activities, the number and incidence of Achilles tendon overuse injuries have increased in the industrialized countries during the last few decades. The term "Achilles paratendinopathy" is used in clinical practice to describe activity-related Achilles pain combined with tenderness on palpation, providing that there is no suspicion of intratendinous pathology on the basis of patient history, clinical examination, or imaging examinations. This article discusses Achilles paratendinopathy.

Abstract
Fibronectin is a large fibril-forming extracellular glycoprotein that seems to be involved in joint diseases. The objective of this study was to investigate the expression of fibronectin in human temporomandibular joint disks obtained from patients with internal derangement and varying extents of disk tissue degeneration/regeneration with that of temporomandibular joint disks free of significant morphological alterations by means of immunohistochemical methods. Twelve adult human temporomandibular joint disks (10 diseased disks and 2 normal disks) were used in this study. Temporomandibular joint disks were fixed in 10% buffered formalin. Sections were then immunohistochemically processed using a monoclonal antibody specific to human fibronectin and streptavidin-biotin detection methods. Positive reactions to fibronectin were found in normal and diseased disk tissues but to a different extent. Normal disk tissues revealed weak fibronectin expression, which was mainly located along the collagen bundles. Temporomandibular joint disks with internal derangement exhibited a higher immunoreactivity. Distinct reticular fibronectin structures were found inside the diseased disk, particularly nearby the newly formed blood vessels, tears, and clefts. In the covering layer of the disk surface, fibronectin was expressed in a fascicular pattern running parallel to the disk surface. The findings suggest that temporomandibular joint disk tissue can express fibronectin and that the expression is more pronounced in disk specimens of patients with internal derangement of the temporomandibular joint, supporting a role of this glycoprotein in the degeneration/regeneration processes of human temporomandibular joint disk tissue.

Abstract
The extracellular matrix (ECM), and especially the connective tissue with its collagen, links tissues of the body together and plays an important role in the force transmission and tissue structure maintenance especially in tendons, ligaments, bone, and muscle. The ECM turnover is influenced by physical activity, and both collagen synthesis and degrading metalloprotease enzymes increase with mechanical loading. Both transcription and posttranslational modifications, as well as local and systemic release of growth factors, are enhanced following exercise. For tendons, metabolic activity, circulatory responses, and collagen turnover are demonstrated to be more pronounced in humans than hitherto thought. Conversely, inactivity markedly decreases collagen turnover in both tendon and muscle. Chronic loading in the form of physical training leads both to increased collagen turnover as well as, dependent on the type of collagen in question, some degree of net collagen synthesis. These changes will modify the mechanical properties and the viscoelastic characteristics of the tissue, decrease its stress, and likely make it more load resistant. Cross-linking in connective tissue involves an intimate, enzymatical interplay between collagen synthesis and ECM proteoglycan components during growth and maturation and influences the collagen-derived functional properties of the tissue. With aging, glycation contributes to additional cross-linking which modifies tissue stiffness. Physiological signaling pathways from mechanical loading to changes in ECM most likely involve feedback signaling that results in rapid alterations in the mechanical properties of the ECM. In developing skeletal muscle, an important interplay between muscle cells and the ECM is present, and some evidence from adult human muscle suggests common signaling pathways to stimulate contractile and ECM components. Unaccostumed overloading responses suggest an important role of ECM in the adaptation of myofibrillar structures in adult muscle. Development of overuse injury in tendons involve morphological and biochemical changes including altered collagen typing and fibril size, hypervascularization zones, accumulation of nociceptive substances, and impaired collagen degradation activity. Counteracting these phenomena requires adjusted loading rather than absence of loading in the form of immobilization. Full understanding of these physiological processes will provide the physiological basis for understanding of tissue overloading and injury seen in both tendons and muscle with repetitive work and leisure time physical activity.

Abstract
BACKGROUND Recalcitrant calcific insertional Achilles tendinopathy is difficult to treat. HYPOTHESIS Bursectomy, excision of the distal paratenon, disinsertion of the tendon, removal of the calcific deposit, and reinsertion of the Achilles tendon with bone anchors is safe and effective. STUDY DESIGN Longitudinal study. METHODS Twenty-one patients (six women) (21 feet) (average age 46.9 +/- 6.4 years) with recalcitrant calcific insertional Achilles tendinopathy were treated surgically with removal of the calcific deposit; the Achilles tendon was reinserted with bone anchors. RESULTS At an average follow-up of 48.4 months, one patient necessitated a further operation. Eleven patients reported an excellent result, and five a good result. The remaining five patients could not return to their normal levels of sporting activity and kept fit by alternative means. The results of the VISA-A questionnaire were markedly improved in all patients, from an average of 62.4% to 88.1%. CONCLUSIONS We recommend disinsertion of the Achilles tendon to excise the calcific deposit fully and reinsertion of the Achilles tendon in the calcaneus with suture anchors. No patient experienced a traumatic disinsertion of the reattached tendon. However, five patients were not able to return to their original level of physical activity.

Abstract
Tendon conditions cause a great deal of morbidity in both elite and recreational athletes, and outcome of treatment is often unsatisfactory. Evidence that the common clinical conditions (e.g., Achilles, patellar, elbow and rotator cuff tendinopathies) are due to tendinosis has been present for many years, yet the misnomer "tendinitis" is still widely used for these conditions in clinical practice. Clinical practice remains very different from evidence-based recommendations [8], but this is a common challenge in medical practice. Thus, in addition to further research in an area of medicine rife for such endeavor, there must be attention to knowledge translation--ensuring that the patient benefits from what is already known.

Abstract
Objective:Tendons have biomechanical properties based on collaborative remodeling of all their cells through normal lysis and synthesis. This review assesses factors that affect the healing response and presents solutions for rehabilitating acute and chronic tendon injuries.Data Sources:MEDLINE (1970–2002) and SPORTDiscus (1970–2002). Key words searched weretendon, tendinitis, tendinosis, tendinopathy, rehabilitation, ultrasound, NSAIDs, exercise, mobilization, aging, immobilization,andhealing.Data Synthesis:The biomechanical roles tendons play change throughout one’s lifetime and are influenced by maturation and aging, injury and healing, immobilization, exercise, medications, and therapeutic modalities. Suggestions from animal, case, and clinical studies are varied but provide solutions in the treatment of acute and chronic tendon injuries.Conclusions and Recommendations:All factors that affect the tendon structure should be considered in a rehabilitation program. Therapeutic exercise, medications, or therapeutic modalities should never be used as a stand-alone therapy.

Abstract
This study was designed to investigate human surgical specimens from patients with impingement (n = 16), ruptured supraspinatus tendons (n = 7), frozen shoulder (n = 2) and controls (n = 9) with respect to histological changes and the presence of fibronectin and Matrix metalloprotease-1 (MMP-1). The biopsy of the middle part of the supraspinatus tendons was analyzed microscopically after staining with hematoxyline eosin, Van Giesons hematoxyline and Phospho Tungstic Acid Hematoxyline for visualization of fibrin. Immunofluorescent stainings for fibronectin and MMP-1 were performed. Histology and immunofluorescence were assessed blindly. Necrotic tendinous tissue and fibrin were found only in some specimens from ruptures. The staining for fibronectin was significantly increased among patients with a rupture. MMP-1 was, however, only infrequently found in specimens from patients with impingement and ruptures. Fibrosis and thinning of fascicles seemed to be a more non-specific finding, appearing in control, impingement and rupture specimens. In conclusion, necrotic tendinous tissue, fibrin and fibronectin appear to be signs of tendon degeneration, whereas fibrosis and thinning of fascicles were found also in controls.

Abstract
Achilles tendinopathy is prevalent and potentially incapacitating in athletes involved in running sports. It is a degenerative, not an inflammatory, condition. Most patients respond to conservative measures if the condition is recognised early. Surgery usually involves removal of adhesions and degenerated areas and decompression of the tendon by tenotomy or measures that influence the local circulation.

Abstract
This study was designed to investigate the histologic expression of the rat's supra- and infraspinatus tendons in carrageenan-induced subacromial bursitis. Thirty-two rats received subacromial injections with carrageenan (n = 28) or saline (n = 4). The tendons were analysed microscopically after staining with hematoxyline eosin, Van Giesons hematoxyline and immunofluorescent staining of fibronectin and fibrinogen. In the controls (saline x 10) and group A (carrageenan x 5) there were no changes in the tendons. In group B (carrageenan x 10) 3/8 rats showed macrophages between the collagen fibres and an increased staining of fibronectin. In group C (double dosis carrageenan) all rats had signs of fibrocartilaginous metaplasia in the supraspinatus tendon. In eight of these specimens even bony metaplasia was seen. The infraspinatus tendon showed fibrosis but no fibrocartilaginous metaplasia. The results showed that iatrogenic bursitis after carrageenan subacromial injections was associated with marked changes of the supraspinatus tendon.

Abstract
We report the outcome of 14 athletes with chronic recalcitrant achillodynia and central core degeneration of the Achilles tendon. The patients underwent surgery after an average time from onset of symptoms to surgery of 87 months. All patients had undergone conservative management, including physical therapy treatment, orthoses, nonsteroidal antiinflammatory drugs, and steroid injections. At an average follow-up of 35 months (range, 27 to 52), only 5 patients had an excellent or good result, despite reexploration in 6 of the 14 patients. In athletes with long-standing pain and central core degeneration of the Achilles tendon, prognosis is poor, and even reexploration is not successful. If the referral pattern allows, surgery should probably be undertaken earlier.

Abstract
Tendonitis is a common diagnosis in sports medicine. The traditional view of tendonitis is a tendon injury resulting from repetitive mechanical load with a subsequent inflammatory response. The English literature from 1966 to the present on the etiology, diagnosis, and treatment of tendonitis was evaluated. There is some scientific support in the literature for the diagnosis of tenosynovitis and tendinosis as a pathologic entity. Actual inflammation of tendon tissue consistent with tendonitis has not been seen clearly in patho-anatomic studies. Conclusive evidence confirming that repetitive mechanical load is a major etiologic factor could not be found. Similarly, strength deficits, inflexibility, and improper equipment have not been studied in a controlled prospective manner. Other factors such as age and tendon vascularity have been consistently correlated with these injuries although their overall importance remains difficult to assess. There are no controlled studies on treatment through physical therapy aimed at flexibility and/or strengthening. Treatment with anti-inflammatory drugs has been studied extensively. However, only nine of 32 studies are prospective and placebo controlled. Some pain relief was found in five of the nine controlled studies, but healing of the tendon problem was not studied in these short follow-up studies. Twenty-three studies on steroid injections were found. Eight were prospective and placebo controlled studies, with three showing beneficial effects of the injection at follow-up. It was concluded that much of the pathology and etiology of tendonitis remains unclear. The possibility must be considered that current treatment methods may not significantly affect the natural history.

Abstract
From August 1989 to January 1995 we performed multiple percutaneous longitudinal tenotomies under local anesthetic on 52 middle- and long-distance runners with unilateral Achilles tendinitis or peritendinitis that had failed conservative treatment. Forty-eight patients were reviewed at an average of 22.1 months (SD, 6.5) after surgery. Results were rated as excellent in 25 patients, good in 12, fair in 7, and poor in 4. Four patients developed subcutaneous hematomas. One patient developed a superficial infection at one of the incision sites, which was managed by oral antibiotics with full recovery. Three patients complained of over-sensitivity to the incisions; this was resolved by rubbing hand cream over the incisions several times a day. One patient developed hypertrophic painful scars on three of the five incisions, but corticosteroid injections yielded good functional and cosmetic results. Isometric strength and endurance of the gastrocsoleus complex was measured just before the procedure, and at 6 weeks and 6 months later. Both were within 10% of the normal contralateral limb by the 6th postoperative month. Percutaneous longitudinal tenotomy is simple, can be performed on an outpatient basis, requires minimal follow-up care, and, in our experience, has produced no significant complications. We use this procedure as the operative treatment of choice for cases of chronic tendinitis that have failed conservative treatment.

Abstract
Although Achilles tendon injuries are common overuse injuries in sports, the exact incidence is unknown, primarily as a result of varying definitions and diagnoses of the underlying pathological changes. Despite numerous studies of treatment of the Achilles tendon injuries, the long-term results are not well known. The results after surgical treatment of chronic partial Achilles tendon ruptures in 64 patients with a follow-up of 6 (1.5-11) years were evaluated in a retrospective study. The ruptures were divided into three groups: (I) proximal (more than 3 cm above the calcaneus), (II) distal and (III) combined (proximal and distal). All patients underwent an operation involving the excision of the devitalized tendon tissue and, in groups (II) and (III), also the excision of the deep Achilles bursa and removal of the dorsal corner of the calcaneus. The functional results were satisfactory in 43 (67%) patients and unsatisfactory in 21 (33%). The results were better in patients with proximal ruptures than in patients with either distal or combined ruptures. Males experienced better results than females. Post-operative immobilization in a plaster cast had no significant influence on the final result. Nine (14%) patients with either a distal or a combined rupture were re-operated on and in seven of them the final result was satisfactory. The conclusion of this study is that partial Achilles tendon ruptures are often difficult to treat and only two out of three patients can be expected to obtain satisfactory results after surgical treatment.

Abstract
Tendon injuries and other tendon disorders represent a common diagnostic and therapeutic challenge in sports medicine, resulting in chronic and long-lasting problems. Tissue degeneration is a common finding in many sports-related tendon complaints. In the great majority of spontaneous tendon ruptures, chronic degenerative changes are seen at the rupture site of the tendon (1). Systemic diseases and diseases specifically deteriorating the normal structure of the tendon (i.e. foreign bodies, and metabolic, inherited and infectious tendon diseases) are only rarely the cause of tendon pathology. Inherited diseases, such as various hereditary diseases with disturbed collagen metabolism and characteristic pathological structural alterations (Ehlers-Danlos syndrome, Marfani syndrome, homocystinuria (ochronosis)), represent approximately 1% of the causes of chronic tendon complaints (2), whereas foreign bodies are somewhat more common and are found in less than 10% of all chronic tendon problems (1). Rheumatoid arthritis and sarcoidosis are typical systemic diseases that cause chronic inflammation in tendon and peritendinous tissues. Altogether, these 'specific' disorders represented less than 2% of the pathological alterations found in the histological analysis of more than 1000 spontaneously ruptured tendons (1, 3, 4). In this material, degenerative changes were seen in a great majority of the tendons, indicating that a spontaneous tendon rupture is a typical clinical end-state manifestation of a degenerative process in the tendon tissue. The role of overuse in the pathogenesis of chronic tendon injuries and disorders is not completely understood. It has been speculated that when tendon is overused it becomes fatigued and loses its basal reparative ability, the repetitive microtraumatic processes thus overwhelming the ability of the tendon cells to repair the fiber damage. The intensive repetitive activity, which often is eccentric by nature, may lead to cumulative microtrauma which further weakens the collagen cross-linking, non-collagenous matrix, and vascular elements of the tendon. Overuse has also been speculated to cause chronic tendon problems, by disturbing the micro- and macrovasculature of the tendon and resulting in insufficiency in the local blood circulation. Decreased blood flow simultaneous with an increased activity may result in local tissue hypoxia, impaired nutrition and energy metabolism, and together these factors are likely to play an important role in the sequence of events leading to tendon degeneration (4). A sedentary lifestyle has been proposed as a main reason for poor basal circulation of the tendon, and presumably is at least partly responsible for the high number of tendon problems in people with a sedentary lifestyle who occasionally take part in high physical activity sports events.

Abstract
Two-thirds of Achilles tendon injuries in competitive athletes are paratenonitis and one-fifth are insertional complaints (bursitis and insertion tendinitis). The remaining afflictions consist of pain syndromes of the myotendineal junction and tendinopathies. The majority of Achilles tendon injuries from sport occur in males, mainly because of their higher rates of participation in sport, but also with tendinopathies a gender difference is probably indicated. Athletes in running sports have a high incidence of Achilles tendon overuse injuries. About 75% of total and the majority of partial tendon ruptures are related to sports activities usually involving abrupt repetitive jumping and sprinting movements. Mechanical factors and a sedentary lifestyle play a role in the pathology of these injuries. Achilles tendon overuse injuries occur at a higher rate in older athletes than most other typical overuse injuries. Recreational athletes with a complete Achilles tendon rupture are about 15 years younger than those with other spontaneous tendon ruptures. Following surgery, about 70 to 90% of athletes have a successful comeback after Achilles tendon injury. Surgery is required in about 25% of athletes with Achilles tendon overuse injuries and the frequency of surgery increases with patient age and duration of symptoms as well as occurrence of tendinopathic changes. However, about 20% of injured athletes require a re-operation for Achilles tendon overuse injuries, and about 3 to 5% are compelled to abandon their sports career because of these injuries. Myotendineal junction pain should be treated conservatively. Partial Achilles tendon ruptures are primarily treated conservatively, although the best treatment method of chronic partial rupture seems to be surgery. Complete Achilles tendon ruptures of athletes are treated surgically, because this increases the likelihood of athletes reaching preinjury activity levels and minimises the risk of re-ruptures. Marked forefoot varus is found in athletes with Achilles tendon overuse injuries, reflecting the predisposing role of ankle joint overpronation. Athletes with the major stress in lower extremities have often a limited range of motion in the passive dorsiflexion of the ankle joint and total subtalar joint mobility, which seems to be predisposing factor for these injuries. Various predisposing transient factors are found in about one-third of athletes with Achilles tendon overuse injuries; of these, traumatic factors (mostly minor injuries) predominate. The typical histological features of chronically inflamed paratendineal tissue of the Achilles tendon are profound proliferation of loose, immature connective tissue and marked obliterative and degenerative alterations in the blood vessels. These changes cause continuing leakage of plasma proteins, which may have an important role in the pathophysiology of these injuries. The chronically inflamed paratendineal tissues of the Achilles tendon do not seem to have enough capacity to form mature connective tissue.

Abstract
Forty-nine patients with Achilles peritendinitis (APT) (11 bilateral) and 31 patients with retrocalcanear bursitis (RCB) (5 bilateral) were treated surgically (altogether 96 heels). There were 37 men and 12 women in the APT group, with a mean age of 38.4 years, and 26 men and 5 women in the RCB group, with a mean age of 32.3 years. Forty-five patients in the APT group and 30 patients in the RCB group were active in sports. All patients had been treated conservatively for at least 6 months (range 6 months to 13 years) without relief of symptoms. The operative method was bilateral longitudinal incision of fascia cruris and trimming of the adhesions to fascia and base of Kager's triangle in APT group, and ablation of the posterior upper corner of os calcaneus in RCB group. In order to assess the ability to return to sports, the healing results were evaluated by questionnaire in 42 patients (47 operations) in the APT group and 25 patients (28 operations) in the RCB group 2-11 years postoperatively. The results were excellent in 27, good in 11, fair in 7 and poor in 2 in the APT group, and excellent in 13, good in 10, fair in 2 and poor in 3 in the RCB group, respectively. Operative treatment of APT and RCB in patients whose symptoms persist after conservative treatment seems to give favourable results in the majority of cases.

Abstract
Achillodynia (Achilles tendon pain) is a significant source of disability to many people taking part in sports. Papers in the English language published since 1986 are reviewed here, grouped into specific subject areas including biomechanics, pathology, general clinical presentations, experimental treatments, steroids, podiatry and surgery. While there has been no dramatic breakthrough in the field, there have been various interesting advances with particular reference to imaging and conservative management, which will hopefully stimulate further studies. Many problems of Achilles tendon lesions in athletes remain unsolved, however, and much is yet to be done to provide adequate and generally effective methods of prevention and conservative treatment.

Abstract
Achilles paratenonitis and medial tibial syndrome are the most common specific overuse injuries among athletes in Finland, and they are a problem especially in endurance sports, such as long-distance running and jogging. Conservative treatment is often successful, but if it fails operative treatment is necessary. The surgical methods developed in Finland, which are widely used in the treatment of Achilles paratenonitis and medial tibial syndrome, are presented with clinical follow-up results in this paper. The patients operated on for Achilles paratenonitis were some years older than the patients operated on for retrocalcaneal bursitis (mean 38.4 versus 32.3 years). Results after operation were excellent or good in 92.4% of 291 patients operated on for Achilles paratenonitis, 84.2% of the 63 operated on for retrocalcaneal bursitis and 79% of the 47 operated on for medial tibial syndrome. All the patients treated operatively were patients in whom conservative treatment had failed. In conclusion, operative treatment of Achilles paratenonitis or medial tibial syndrome in athletes is indicated when these complaints do not respond to any type of conservative treatment.

Abstract
Achilles tendon injuries are common in runners. The aim of the present study was to analyse the training programme, any Achilles tendon problems, muscle tightness and range of motion of the ankle joint, and concentric and eccentric muscle torques of the calf muscles in middle-distance runners with and without Achilles tendon problems. Eighty-three middle-distance runners answered a questionnaire on their sports background, training habits and any injuries. Thirty-four percent had suffered from some type of problem relating to the Achilles tendon. Ten of the athletes who had suffered from Achilles tendon problems and ten who had never had any Achilles tendon trouble were randomly selected. These 20 runners underwent a clinical examination. The range of motion of the ankle joint was recorded objectively by a hydraulic and computerised isokinetic dynamometer by measuring resistance to passive motion. Concentric and eccentric muscle torques of the gastrocnemius-soleus complex were recorded. The runners with Achilles tendon problems had trained for significantly more years and covered significantly longer distances per week than runners without Achilles tendon problems. There were no significant differences in other training methods or in best results over 800 m and 1500 m. Runners with Achilles tendon problems had a significantly lower range of motion of the ankle joint. They also had significantly lower eccentric torques of the gastrocnemius-soleus complex, but no differences in concentric torques were found between the groups.

Abstract
Overuse injuries represent a significant percentage of injuries seen in a sports medicine setting. Sports medicine health professionals evaluate and treat patients with the overuse injury of chronic Achilles peritendinitis. This paper reviews the anatomy of the Achilles tendon and presents recent literature concerning the etiology, pathophysiology, and rehabilitation of chronic Achilles peritendinitis. A rehabilitation program is outlined addressing the specific demands of the chronically injured Achilles tendon. J Orthop Sports Phys Ther 1991;13(4):171-176.

Abstract
Ten intact and 22 ruptured Achilles tendons were studied by immunohistochemical techniques. In intact tendons, both fibronectin and laminin were found in vascular walls, myotendineal junction, and endomysium, but not in the connective tissue of the tendons. In ruptured tendons the distribution of laminin was not changed. Fibronectin deposits, on the contrary, could be detected on the tear surface and in the collagen fibers of the ruptured tendons.
