• #1 Tendinosis – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK448174/

  Tendinopathy is a broad term that describes tendon pain and dysfunction without specifying the underlying pathology. […] The etiology of tendinosis is not well understood. Because it was previously thought to be the result of chronic tendinitis, it was hypothesized that chronic inflammation leads to structural tissue changes and tendon calcification. […] Multiple factors, including age, genetic predisposition, and comorbidities, can contribute to healing failure, increasing the risk of tendinosis. […] Tendinosis refers to a degenerative process within a tendon without histologic changes. Tendinopathy is a failure of the healing cascade in which micro injuries occur more quickly than tissue repair. […] Tendinopathy is commonly used as an umbrella term for acute and chronic tendinitis, tendon ruptures, and tenosynovitis, which is inflammation of the tendinous sheath and paratenon tissue.

• #1 Tendinopathy: What It Is, Symptoms, Causes & Treatment

  https://my.clevelandclinic.org/health/diseases/22289-tendinopathy

  Tendinopathy causes chronic pain and declining functionality in a tendon. It gets worse the more you try to use it. Tendinopathy is any condition that affects a tendon, making it painful to use and reducing its functionality. Most people injure their tendons by overusing them although other factors can contribute to weakening of your tendons. Tendinopathy can begin when a tendon injury cant heal. Eventually, destructive changes begin to occur. […] Its not always clear how tendinopathy develops, but it often starts with overusing your tendon. How much force your tendon can tolerate may differ from the next person. Athletes can strain their tendons by overtraining. People who arent regularly active can strain a tendon by suddenly increasing their activity. Any task repeated too often without enough rest in between can cause a repetitive strain injury.

• #1 Tendinopathy (Tendonitis) | Better Health Channel

  https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/tendonitis

  Tendinopathy is usually a type of overuse injury, where the tendon is repeatedly strained until tiny tears form. […] Some of the common causes of tendinopathy can include: overuse of the tendons by repetitive actions, calcium deposit along the tendon at the site of insertion (where it attaches to the bone), bone spurs on the heels, any sporting activity that requires lots of jumping and running, running on hard surfaces, poor sporting technique, such as holding a tennis racquet or golf club incorrectly, inappropriate sporting equipment, such as a tennis racquet that’s too heavy, lifting weights that are too heavy, lifting heavy weights without warming up properly, neglecting to warm up properly before doing sport or exercise, extreme and regular physical effort, such as an intensive sports training schedule, not taking enough time between training sessions to allow full recovery, exercising in cold temperatures, awkward positions that are maintained for a long time, being obese, which puts excessive pressure on the tendons of the legs.

• #1 Tendinopathy – Symptoms and causes – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/tendinopathy/symptoms-causes/syc-20580660

  Tendinopathy is a term for any condition that affects a tendon. Tendons are cords that attach muscle to bone. Tendinopathy, which can cause pain and tenderness, is common. It is often caused by overuse or repeated movement and tends to affect certain tendons in the arm or leg. […] Tendinopathy can be caused by wear and tear on a tendon. This can happen due to overuse or naturally over time as people age and their tendons become less flexible. Most people develop tendinopathy because their jobs or hobbies involve motions they repeat over and over. Jobs such as carpentry or house painting or sports such as baseball, tennis and golf require the same motions to be repeated. Over time, this puts stress on the tendons. Some tendinopathies also can be caused by sudden injury such as a fall or accident. […] How you move when doing your sport or activity can affect your risk of developing tendinopathy. Moving incorrectly can overload the tendon. Having proper form and technique is especially important when having to repeat movements for sports or a job.

  Factors that may contribute to straining your tendon include: High-intensity training, Poor ergonomics or equipment, Lack of flexibility, Lack of strength, Muscle imbalances, Posture or gait abnormalities, Too much weight on your tendon, Certain autoimmune diseases. […] When you strain your tendon, small tears in the fibers can form. Tendons are strong, but when they tear, theyre slow to heal. Acute inflammation (tendinitis) is your bodys way of starting the healing process. But if your tendon doesnt get the rest it needs to heal, chronic tendinopathy can set in. Tendinitis might continue long-term, or tendinosis might begin the process of remodeling your tendon.

• #1 Achilles Tendinitis – OrthoInfo – AAOS

  https://orthoinfo.aaos.org/en/diseases–conditions/achilles-tendinitis/

  Achilles tendinitis is typically not related to a specific injury. The problem results from repetitive stress to the tendon. This often happens when we push our bodies to do too much, too quickly. Other factors can also make a person more likely to develop Achilles tendinitis, including: […] A sudden increase in the amount or intensity of exercise activity. For example, increasing the distance you run every day by a few miles without giving your body a chance to adjust to the new distance may cause irritation and inflammation. […] Tight calf muscles. Calf muscle tightness puts extra stress on the Achilles tendon, especially where it inserts into the heel bone. […] Haglund’s deformity. This is a condition in which there is enlargement of the bone on the back of the heel. This can rub on the Achilles tendon and cause inflammation and pain.

• #1 Tendinitis – Symptoms and causes – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/tendinitis/symptoms-causes/syc-20378243

  Tendinitis can be caused by a sudden injury. But repeating the same movement over time is a much more likely cause. Most people develop tendinitis because their jobs or hobbies involve motions that they repeat, over and over. This puts stress on tendons. […] Moving correctly is especially important when having to repeat movements for sports or a job. Moving incorrectly can overload the tendon and lead to tendinitis. […] Risk factors for developing tendinitis include age, having jobs that involve doing the same motion over and over, doing physical activities with poor form, and taking certain medicines. […] Certain medical conditions, such as diabetes, can increase the risk of tendinitis. Medications that may increase risk include antibiotics known as fluoroquinolines, corticosteroids such as cortisone, and aromatase inhibitors, used to lower breast cancer risk.

• #1 Tendinopathy: Symptoms, causes, and treatment

• #1 6 Risk factors for tendinopathy you need to know

  https://www.physiotutors.com/risk-factors-for-tendinopathy/

  Tendinopathy has a multifactorial etiology that is not well understood. […] The most common cause for tendinopathy is training errors involving sudden changes in load. […] Higher Load duration, intensity, and frequency are associated with patellar pain and Achilles tendinopathy. […] Individual biomechanics, including movement kinetics and kinematics, foot posture, flexibility, neuromuscular capacity, and structural anatomy may influence tendinopathy risk. […] Multiple systemic factors have been linked with tendinopathy including age, high cholesterol, adiposity, and genetics. […] Systemic factors might also play a greater role in the case of bilateral involvement or in tendinopathy where load seems to play a smaller role such as in pes anserinus tendinopathy. […] The envelope of function is the load/frequency distribution that defines the safe or homeostatic range of load acceptance.

  https://www.merckmanuals.com/professional/musculoskeletal-and-connective-tissue-disorders/bursa-muscle-and-tendon-disorders/tendinitis-and-tenosynovitis

  Tendinopathy usually results from repeated small tears or degenerative changes (sometimes with calcium deposits) that occur over years in the tendon. […] The cause of tendinitis is often unknown. It usually occurs in people who are middle-aged or older as the vascularity of tendons decreases; repetitive microtrauma may contribute. Repeated or extreme trauma (short of rupture), strain, and excessive or unaccustomed exercise probably also contribute. Some fluoroquinolone antibiotics may increase the risk of tendinopathy and tendon rupture. […] Risk of tendinitis may be increased by certain systemic disorders most commonly rheumatoid arthritis, systemic sclerosis, gout, reactive arthritis, and diabetes or, very rarely, amyloidosis or markedly elevated blood cholesterol levels. […] Fluoroquinolone antibiotic use has been associated with tendinopathies, including tendon rupture.

• #1 The Basic Science of Tendinopathy

  https://pmc.ncbi.nlm.nih.gov/articles/PMC2505234/

  Tendinopathy is a common clinical problem with athletes and in many occupational settings. Tendinopathy can occur in any tendon, often near its insertion or enthesis where there is an area of stress concentration, and is directly related to the volume of repetitive load to which the tendon is exposed. Recent studies indicate tendinopathy is more likely to occur in situations that increase the dose of load to the tendon enthesis including increased activity, weight, advancing age, and genetic factors. […] Tendinopathy has an increased incidence with age and the male gender and with obesity. Excessive long-distance running, intensity, and hill work are risk factors for acute Achilles tendinopathy; distance and excessive time spent swimming are associated with supraspinatus tendinopathy. There is also an association between tendinopathy and hormone replacement therapy and oral contraceptives in women.

• #1 Tendinopathy and Tenosynovitis: Symptoms and Treatment

  https://patient.info/bones-joints-muscles/tendinopathy-and-tenosynovitis-tendinosis

  This is a rare cause. The infection may occur because a cut or puncture wound to the skin over a tendon may allow germs (bacteria) to get in to infect the tendon and/or tendon sheath. However, infection sometimes spreads from other parts of the body via the bloodstream to infect a tendon sheath. […] These problems are more common in middle-aged adults and particularly in people who are quite sporty. […] If your problem is work-related, your employer has a legal duty to try to prevent the development of tendinopathy or tenosynovitis by making the work environment comfortable and doing whatever is reasonable to achieve this. […] There is no proof that anything can prevent a bout of tenosynovitis or tendinopathy. However, the following are sensible suggestions that may help to prevent either coming back: Avoid a sudden increase in repetitive movements and overuse of the affected area. […] Physical therapy to strengthen the muscles around the affected tendon may help.

• #1 Tendinopathy – Wikipedia

  https://en.wikipedia.org/wiki/Tendinopathy

  Causes may include an injury or repetitive activities. […] Less common causes include infection, arthritis, gout, thyroid disease, and diabetes. […] Obesity, or more specifically, adiposity or fatness, has also been linked to an increasing incidence of tendinopathy. […] Quinolone antibiotics are associated with increased risk of tendinitis and tendon rupture. […] The most commonly accepted cause for this condition is seen to be an overuse syndrome in combination with intrinsic and extrinsic factors leading to what may be seen as a progressive interference or the failing of the innate healing response. […] Tendinopathy involves cellular apoptosis, matrix disorganization and neovascularization. […] Classic characteristics of „tendinosis” include degenerative changes in the collagenous matrix, hypercellularity, hypervascularity, and a lack of inflammatory cells which has challenged the original misnomer „tendinitis”.

• #1 Tendinosis – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK448174/

  A common theory suggests that an altered tendon environment disrupts proper cell recruitment and the healing cascade. […] Various systemic and lifestyle factors contribute to tendon injury risk, including body mass index, nutrition, body mechanics, muscle imbalances, and flexibility, all of which influence tendon loading and stress. […] Tendon ruptures have a 46-fold occurrence when concurrently exposed to fluoroquinolones and corticosteroids. […] The differential diagnoses for tendinosis include the following: Acute compartment syndrome, Ankle injury, Bursitis, Carpal tunnel syndrome (in emergency medicine), Gout and pseudogout, Hand infections, Reactive arthritis, Rheumatoid arthritis, Rotator cuff injuries, Soft tissue knee injury. […] Tendinosis healing can last 3 to 6 months, but therapy, rest, and medication can improve the outlook. If left untreated, tendinosis can result in tendon rupture.

  Tendonitis occurs when your tendons—tissue that connects your muscles to your bones—become inflamed and swollen. This can happen anywhere on your body, but is most commonly seen in joints: shoulders, elbows, knees, wrists, and heels. […] Most people get tendonitis by overusing or misusing the affected tendon. Common scenarios include: You overuse your tendon due to your occupation or favorite hobby, such as: Carpentry, Painting, Gardening/landscaping, Housecleaning, Playing a musical instrument, Playing certain sports (namely golf, baseball or tennis). […] You misuse your tendon by exercising improperly, such as: Exercising intensely but not frequently (like weekend warriors who do intense workouts, but only on the weekends), Not warming up before your workout or cooling down after your workout, Using improper form and bad posture, Wearing improper footwear, Taking on too much too soon.

  https://hartfordsportsorthopedics.com/what-causes-tendon-wear-and-tear-called-tendinopathy-south-windsor-enfield-glastonbury-ct/

  I am frequently asked about the cause of those wear and tear changes we see in the tendons of the rotator cuff and elsewhere in the body. In general, I explain it is a result of those age related changes that we all experience in life. […] Conventional thinking says that tendinopathy—defined as chronic tendon degeneration—is due to tendon overload, leading to microscopic collagen fiber failure and a failed healing response. […] But according to recent studies tendinopathy may be due to mechanical understimulation of tendon cells, rather than tendon overload, and that abnormal differentiation of tendon stem cells may play a role in the development of the condition. […] According recent studies have demonstrated that stress deprivation leads to increases of collagenase (which breaks down collagen in tendons) expression and a loss of tendon cells.

• #1 Tendinopathy – Wikipedia

  https://en.wikipedia.org/wiki/Tendinopathy

  Examination of pathologic tennis elbow tissue reveals noninflammatory tissue, so the term „angiofibroblastic tendinosis” is also used. […] Load-induced non-rupture tendinopathy in humans is associated with an increase in the ratio of collagen III:I proteins, a shift from large to small diameter collagen fibrils, buckling of the collagen fascicles in the tendon extracellular matrix, and buckling of the tenocyte cells and their nuclei.

  More than a decade of research has shown that microscopic collagen fiber failure may play an important role in the development of tendinopathy. […] Stem cells may also play a role in the development of tendinopathy. […] The expression of inflammatory mediators may occur in the early stages of tissue injury. […] Recent studies have found that mechanical understimulation of tendon cells, rather than tendon overload, may cause tendinopathy and that abnormal differentiation of tendon stem cells may play a role in its development. […] Research also indicates important interactions occur among load, inflammatory mediator expression, and MMP expression at the microscopic level. […] MMP inhibitors may have the potential to prevent ongoing tendon degeneration.

• #1 Sustained Exposure of Substance P Causes Tendinopathy

  https://www.mdpi.com/1422-0067/21/22/8633

  Sustained exposure to substance P may be involved in the development of tendinopathy. […] The effects of substance P on tendinopathy remain unclear. […] The underlying biological mechanism and advancement of disease is not clear. […] However, other studies state the contrary that substance P accounts for a critical component of tendon healing. […] In this study, we hypothesized that substance P may be the cause of tendinopathy. […] While brief exposure to substance P is closely related to tendon healing, repetitive long-term exposure is strongly linked to the development of tendinopathy. […] Our analyses indicate that long-term exposure to substance P is one of the causes of tendinopathy.

• #1 Tendinopathies of the Foot and Ankle | AAFP

  https://www.aafp.org/pubs/afp/issues/2009/1115/p1107.html

  Because our understanding of tendinopathy has evolved in recent years, the condition is now considered a degenerative process; this affects the approach to treatment. […] Achilles tendinopathy is often caused by overtraining, use of inappropriate training surfaces, and poor flexibility. […] Recent data have demonstrated that overuse tendon injuries are not caused by persistent inflammation. […] These overuse injuries are most likely to occur when the mode, intensity, or duration of physical activity or athletic training changes in some way. […] A normal response to tendon injury consists of inflammation (i.e., tendinitis) followed by deposition of collagen matrix within the tendon and remodeling (i.e., tendinosis). […] However, a failed healing response may occur because of ongoing mechanical forces on the tendon, poor blood supply, or both.

• #1 What causes tendonitis? | Top Doctors

  https://www.topdoctors.co.uk/medical-dictionary/tendonitis

  Tendonitis (also called tendinitis) refers to inflammation of a tendon. It is one of the major sub-types of tendinopathy (tendon disease), along with tendinosis and paratenonitis. […] There are two main direct causes of tendonitis: sudden injury and repetitive movements over time. These repetitive movements could be anything from movements made during activities like gardening, painting or cleaning to sports, such as tennis or golf. Bad posture and not warming up properly before exercise can also lead to tendonitis. […] Age, in fact, is the most common tendonitis-associated risk factor. As we age, our tendons lose their elasticity, and become less flexible and easier to injure or tear. Other risk factors include jobs involving repetitive movements, sport (particularly weekend warriors, who are relatively inactive during the week, but push themselves hard at the weekend), and certain health conditions, such as diabetes and rheumatoid arthritis, which seem to go hand-in-hand with a greater likelihood of developing tendonitis.

• #1 The Basic Science of Tendinopathy

  https://pmc.ncbi.nlm.nih.gov/articles/PMC2505234/

  These findings suggest there is a genetic predisposition to the development of tendinopathy. However, no specific causative gene has been linked to tendinopathy, suggesting that tendinopathy may be polygenic and may involve complex interaction between multiple genes. […] The aim of this review was to identify recent advances in the understanding of tendinopathy, particularly from a cell and molecular biology perspective. Our current hypothesis is that tendinopathy is induced when tendon cells experience a large volume of repetitive load. Tendons of certain anatomical locations are more susceptible as are individuals who are older, heavier and male in those genetically predisposed to tendinopathy. There is debate as to whether a loss of integrity of the matrix, or the cells in the tendon matrix, initiate the changes in tendinopathy.

  Tendinosis happens when collagen that forms a tendon breaks down and worsens over time. Overuse of a tendon is a common cause, and if the injury isnt allowed to heal, it can become chronic. […] Common causes of tendinosis include dealing with an acute injury, overuse of a tendon, or the way you position yourself when performing tasks such as typing at your keyboard. […] Tendinosis is most often caused by repetitive muscle movements, minor impact on the affected area, or a sudden, more serious injury. […] Other risk factors include poor posture, bone or joint abnormalities (such as length differences in your legs or arthritis in a joint) that can put stress on tendons. […] Occasionally, an infection can cause tendinosis, especially if its caused by a cat or dog bite to the hand or a finger.

  If tendonitis is not properly managed, it can become tendinosis. Tendinosis is a more serious, chronic condition that happens due to overuse and not enough time for the tendon to heal. Scar tissue can then develop, causing chronic pain and reduced function. This condition can take much longer to heal. Treatment can take several months. […] Tendonitis treatment starts with resting the area that hurts. Your child should stop any activity that causes pain. Physical therapy or home exercises may be recommended to help correct improper body movement. Ice and anti-inflammatory medication can help relieve pain and swelling while your child rests. In severe cases, if not treated, tendonitis can lead to tendon rupture, which may need surgery. […] While tendonitis is a common injury, you can help your child avoid it by: Encouraging a variety of activities to prevent overuse of specific tendons, Ensuring they warm up and cool down properly, Making sure your child uses proper equipment for their sport or activity, Promoting balanced nutrition and staying hydrated, Listening to your child if they complain of pain or discomfort.

  Tendinopathy is a catch-all term used to describe the conditions of tendonitis (or tendinitis) and tendonosis. Tendinopathies are injuries that occur in tendons, which are structures that attach muscle to bone. […] Most tendon injuries are caused by overuse of the specific muscle group. These injuries are common in athletes who do the same activity over and over again. Running and jumping, overhead hitting and throwing, commonly lead to overuse injuries. The injury can be made worse by poor conditioning, technique, and nutrition. External factors such as poor coaching, improper equipment, and sport environment can also contribute to tendinopathy. […] There is little information on the prevention of tendonitis and tendinosis. Focus should be placed on proper functional technique in sport, and balanced training of the entire body. Athletes with a propensity for tendon problems should also be aware that prolonged time off and rapid changes in training programs may predispose them to future injury.

  Tendinopathy has a multifactorial etiology that is not well understood. Risk factors are often separated into extrinsic (those acting on the body) and intrinsic groups (those acting from within the body). […] Too much load is clearly linked to tendinopathy, but there appears to be large variation in how much load individuals can endure before developing tendinopathy. […] These individual intrinsic factors are likely to reduce tolerance or capacity to withstand load. […] The most common cause for tendinopathy is described as training errors. This is an ambiguous term, but is normally considered to encompass any alterations in physical load on the tendon. […] The current body of evidence suggests the pathogenesis of tendinopathy involves a change in tissue homeostasis. […] Multiple systemic factors have been linked with tendinopathy including: age, lipid levels, adiposity and genetics. […] The exact mechanism by which systemic factors influence tendinopathy risk is largely unknown. […] We know that previous injury appears to be an important predictor of tendinopathy.

  https://aidyourtendon.com/strain-injuries/chronic-tendinitis.php

  You might say to yourself „How did I get chronic tendonitis”? It all started with an acute or overuse (repetitive movement) injury to your tendon. […] Chronic tendinitis can take more than 6 weeks to heal, and sometimes goes on for years, when it is left untreated. […] Tendinosis is caused by chronic degeneration (wearing away) of tendon fibers over time. […] Where tendonitis is damage or micro-tearing to your tendon, tenosynovitis is damage or micro-tearing to the sheath covering your tendon. […] Chronic means re-occurring, your pain and injury is coming back because you haven’t given it enough time to repair the tendon tissue. […] When the tendon gets inflamed it is known as tendonitis, and when the tendons are chronically overused, it may lead to microscopic tears in the collagen matrix and causes a gradual weakening of the tissues. […] Oral Medications can mask the pain but do not aid in the healing of tendonitis. Anti-inflammatories and pain killers can mask the pain and indirectly cause tendonitis to worsen.

  Tendonitis is most commonly caused by overuse (repetitive stress), but less often, it can also occur in areas where calcium deposits have developed. […] The confusion regarding these two spellings is complicated further by the fact that tendonitis is one of the two main types of tendinopathy, which refers more broadly to any painful condition in or around the tendons caused by overuse. […] A person who experiences recurring tendonitis problems may develop tendinosis, although the latter condition can also arise as a result of an acute injury or other cause. […] It is very important that you do not neglect persistent tendonitis, since recurring tendonitis can lead to degeneration of the tendon, known as tendinosis. […] In some cases, persistent tendon inflammation combined with overuse especially of the Achilles tendon or shoulder rotator cuff tendons may lead to weakening and subsequent rupture of the tendon.

  https://www.healthline.com/health/tendinopathy

  Tendinopathy is a condition in which a tendon becomes painful and has limited range of motion. More common than tendonitis, tendinopathy can be caused by many things, like aging, stress, or injury. […] Tendinopathy is a degeneration of the collagen protein that forms the tendon. […] Both tendinopathy and tendonitis are often caused by overuse of or sudden stress on a tendon. Aging and lack of muscle tone can also play a role in the development of tendinopathy. […] Doctors previously thought that tendinopathy was an eventual result of tendonitis. But after looking at samples of injured tendons under a microscope, many now believe it’s the other way around tendonitis is an eventual result of tendinopathy.

  https://www.mayoclinic.org/diseases-conditions/tendinopathy/symptoms-causes/syc-20580660

  Tendinopathy is a term for any condition that affects a tendon. Tendons are cords that attach muscle to bone. Tendinopathy, which can cause pain and tenderness, is common. It is often caused by overuse or repeated movement and tends to affect certain tendons in the arm or leg. […] Tendinopathy can be caused by wear and tear on a tendon. This can happen due to overuse or naturally over time as people age and their tendons become less flexible. Most people develop tendinopathy because their jobs or hobbies involve motions they repeat over and over. Jobs such as carpentry or house painting or sports such as baseball, tennis and golf require the same motions to be repeated. Over time, this puts stress on the tendons. Some tendinopathies also can be caused by sudden injury such as a fall or accident. […] How you move when doing your sport or activity can affect your risk of developing tendinopathy. Moving incorrectly can overload the tendon. Having proper form and technique is especially important when having to repeat movements for sports or a job.

  These findings suggest there is a genetic predisposition to the development of tendinopathy. However, no specific causative gene has been linked to tendinopathy, suggesting that tendinopathy may be polygenic and may involve complex interaction between multiple genes. […] The aim of this review was to identify recent advances in the understanding of tendinopathy, particularly from a cell and molecular biology perspective. Our current hypothesis is that tendinopathy is induced when tendon cells experience a large volume of repetitive load. Tendons of certain anatomical locations are more susceptible as are individuals who are older, heavier and male in those genetically predisposed to tendinopathy. There is debate as to whether a loss of integrity of the matrix, or the cells in the tendon matrix, initiate the changes in tendinopathy.

[…] Often, it is a combination of factors that leads to a tendon disorder, and every situation is unique. Causes can include overuse as well as age, injury, or disease-related changes in the tendon. Risk factors for tendon disorders can include excessive force, repetitive movements, frequent overhead reaching, vibration, and awkward postures.

  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. […] 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. […] Other factors such as age and tendon vascularity have been consistently correlated with these injuries although their overall importance remains difficult to assess. […] 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.

  Because our understanding of tendinopathy has evolved in recent years, the condition is now considered a degenerative process; this affects the approach to treatment. […] Achilles tendinopathy is often caused by overtraining, use of inappropriate training surfaces, and poor flexibility. […] Recent data have demonstrated that overuse tendon injuries are not caused by persistent inflammation. […] These overuse injuries are most likely to occur when the mode, intensity, or duration of physical activity or athletic training changes in some way. […] A normal response to tendon injury consists of inflammation (i.e., tendinitis) followed by deposition of collagen matrix within the tendon and remodeling (i.e., tendinosis). […] However, a failed healing response may occur because of ongoing mechanical forces on the tendon, poor blood supply, or both.

  Tendinopathy has a multifactorial etiology that is not well understood. Risk factors are often separated into extrinsic (those acting on the body) and intrinsic groups (those acting from within the body). […] Too much load is clearly linked to tendinopathy, but there appears to be large variation in how much load individuals can endure before developing tendinopathy. […] Less active people also suffer tendinopathy, suggesting that the effect of load is likely to be moderated by intrinsic factors. […] These individual intrinsic factors are likely to reduce tolerance or capacity to withstand load. […] The most common cause for tendinopathy is described as training errors. This is an ambiguous term, but is normally considered to encompass any alterations in physical load on the tendon.

  Achilles tendinopathy is a painful syndrome affecting the Achilles tendon (which attaches your calf muscles to your heel bone). […] In most cases, Achilles tendinopathy is an overuse injury. […] Some of the causes of Achilles tendonitis include: overuse injury this occurs when the Achilles tendon is stressed until it develops small tears and degeneration. Runners seem to be the most susceptible. People who play sports that involve jumping, such as basketball, are also at increased risk […] arthritis Achilles tendonitis can be a part of generalised inflammatory arthritis, such as ankylosing spondylitis or psoriatic arthritis. In these conditions, both tendons can be affected […] foot problems some people with flat feet or hyperpronated feet (feet that turn inward while walking) are prone to Achilles tendonitis. The flattened arch pulls on calf muscles and keeps the Achilles tendon under tight strain. This constant mechanical stress on the heel and tendon can cause inflammation, pain and swelling of the tendon. Being overweight can make the problem worse

  Tendinopathy usually results from repeated small tears or degenerative changes (sometimes with calcium deposits) that occur over years in the tendon. […] The cause of tendinitis is often unknown. It usually occurs in people who are middle-aged or older as the vascularity of tendons decreases; repetitive microtrauma may contribute. Repeated or extreme trauma (short of rupture), strain, and excessive or unaccustomed exercise probably also contribute. Some fluoroquinolone antibiotics may increase the risk of tendinopathy and tendon rupture. […] Risk of tendinitis may be increased by certain systemic disorders most commonly rheumatoid arthritis, systemic sclerosis, gout, reactive arthritis, and diabetes or, very rarely, amyloidosis or markedly elevated blood cholesterol levels. […] Fluoroquinolone antibiotic use has been associated with tendinopathies, including tendon rupture.
